Answer:

(Amino acids are the building blocks of proteins.) A type of RNA called transfer RNA (tRNA) assembles the protein, one amino acid at a time.

Explanation:

Amino acids are small organic molecules that are the building blocks of proteins. They have an alpha (central) carbon atom linked to an amino group, a carboxyl group, a hydrogen atom, and a variable part called a side chain.

Proteins are big biomolecules and macromolecules that are composed of one or more long chains of amino acid residues. Proteins can be classified as either macromolecules or biomolecules.

Amino acids are the fundamental components of proteins. They are tiny chemical compounds that contain an alpha (central) carbon atom that is coupled to an amino group, a carboxyl group, a hydrogen atom, and a variable component that is referred to as a side chain.

They are responsible for the majority of the work that occurs within cells and are necessary for the structure, function, and control of the organs and tissues found throughout the body.

Respiration

Explanation:

Respiration is the process by which cells obtain chemical energy

Answer: Cell biology encompasses both prokaryotic and eukaryotic cells and can be divided into many sub-topics which may include the study of cell metabolism, cell communication, cell cycle, biochemistry, and cell composition. Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes, but a eukaryotic cell is typically larger than a prokaryotic cell, has a true nucleus (meaning its DNA is surrounded by a membrane), and has other membrane-bound organelles that allow for compartmentalization of functions. The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. ... The nucleus is only one of many membrane-bound organelles in eukaryotes. Prokaryotes, on the other hand, have no membrane-bound organelles.

Answer and Explanation

Explain why populations tend not to continue to increase exponentially in an environment: The exponential growth model is based on unlimited resource availability which means that there is no effect depending on density. There is no competition for resources. Natality and mortality rate do not depend on density. There is a constant growth rate per capita and it is proportional to the population size. A population that exhibits exponential growth model increases in proportion to its size. In the Logistic growth model, the population growth depends on density, the natality and mortality rate depends on the population size, which means that there is no independence between population growth and population density.

When a population grows in a limited space, density rises gradually and eventually affects the multiplication rate. The population's per capita growth rate decreases as population size increases. The population reaches a maximum point delimited by available resources, such as food or space. This point is known as the carrying capacity, K.

Explain what is meant by environmental resistance: It refers to the limiting factors. There are factors and conditions that regulate the population growth, that might be biotic or abiotic, and that avoid the over-growth of a population in a certain space. It results in a natural equilibrium of its biotic potential.  

Explain what is meant by carrying capacity: The carrying capacity K is the maximum point delimited by available resources, such as food or space.

K is a constant that coincides with the size of the population at the equilibrium point when the natality rate and the mortality rate get qual to each other.

Explain the importance of carrying capacity to the growth and maintenance of population numbers: If the population size, N, is inferior to K (N<K) the population can still grow. When N approximates to K, the population´s growth speed decreases. When N=K, the population reaches equilibrium, and when N is superior to K (N>K) the population must decrease in size because there are not enough resources to maintain that size.  

Explain why a newly introduced consumer (e.g. rabbit) would initially exhibit a period of exponential population growth: The example of the rabbit is a case of invasion. Biologic Invasions refer to new species that disperse and establish in a new area far or out of their original distribution range. Once established, these species expand their distribution from the first invaded spot and overgrows. Once stablished, they expand. In the new area, they have less environmental pressure and better conditions than in their origin area -fewer predators, more resources, better nitches-, and these factors favor their overgrowth and consequently uncontrolled expansion. At this point, the population is exhibiting exponential growth. They have enough food available, they might not have predators, they do not have enough competitors for food or space, and if they do they are adapted to live under harder conditions so they are able to compete. The new species is not suffering from the effects of limiting factors yet.  

Describe a likely outcome for a rabbit population after the initial rapid increase had slowed: There are some typical steps in an invasion process:

1) Introduction or dispersion to the new area,

2) Naturalization. The new species establishes in the new area. It can grow, reproduce and make use of resources.

3) Overgrowth and uncontrolled expansion.  Exponential growth

4) Interaction with other species.  At this point, they compete for limiting factors such as food or space. Their population is big enough to be affected by resource availability and by other species that interact with them. The invasive species reach the point in the curve where they stabilize.

5) Stabilization. They reach an equilibrium point.  

Describe the effect that introduced grazing species might have on the carrying capacity. The introduced species expand fast and consume too many resources. Available resources, such as food or space, decrease.

The populations tend not to continue to increase exponentially in an environment due to various environmental factors which restricts or limits its growth.

Environmental resistance refers to environmental factors that restrict the biotic potential of an organism or limit the increase in population. Carrying capacity refers to average population of specie's size in a particular habitat. The importance of carrying capacity to the growth and maintenance of population number because carrying capacity provides resources to a specific population of organisms.

Newly introduced consumer (e.g. rabbit) would initially exhibit a period of exponential population growth because of no predator present in the environment. The introduction of predators which feeds on rabbit is the outcome for a rabbit population after the initial rapid increase had slowed

There is a great effect of introduced grazing species might have on the carrying capacity because more introduced grazing species removes all the vegetation present in that environment which leads to imbalance of ecosystem.

Answer:

The correct answer is - The neuron's intracellular charge must get more positive to meet a certain  thresh hold in order to depolarize. If the neuron does not hit that threshold, then the  neuron will not fire

Explanation:

In neuroscience, the depolarization of neurons shows the all or none law which is also called as all or nothing response. It states that all action potentials have the same size and the potential or strength of a nerve cell does not depend on the stimulus strength as all are the same size.

If a stimulus reaches a particular threshold cell or fiber will fire so either it will fire or not cross the threshold this is all or nothing response or law and depolarization is an example of it.

Answer:

Soil in this text is a natural body comprised of solids

(minerals and organic matter), liquid, and gases that occurs

on the land surface, occupies space, and is characterized by

one or both of the following: horizons, or layers, that are

distinguishable from the initial material as a result of additions,

losses, transfers, and transformations of energy and matter or

the ability to support rooted plants in a natural environment

(Soil Survey Staff, 1999). This definition is expanded from the

previous version of Soil Taxonomy (Soil Survey Staff, 1975) to

include soils in areas of Antarctica where pedogenesis occurs

but where the climate is too harsh to support the higher plant

forms.

The upper limit of soil is the boundary between soil and

either air, shallow water, live plants, or plant materials that

have not begun to decompose. Areas are not considered to have

soil if the surface is permanently covered by water too deep

(typically more than about 2.5 m) for the growth of rooted

plants. The horizontal boundaries of soil are areas where the soil

grades to deep water, barren areas, rock, or ice. In some places

the separation between soil and non soil is so gradual that clear

distinctions cannot be made.

The lower boundary that separates soil from the non soil

underneath is most difficult to define. Soil consists of the

horizons near the earth’s surface that, in contrast to the

underlying parent material, have been altered by the interactions

of climate, relief, and living organisms over time. Commonly,

soil grades at its lower boundary to hard rock or to earthy

materials virtually devoid of animals, roots, or other marks

of biological activity. The lowest depth of biological activity,

however, is difficult to discern and is often gradual. For

the practicality of soil survey, the lower boundary of soil is

arbitrarily set at 200 cm. In soils where either biological activity

or current pedogenic processes extend to depths greater than

200 cm, the lower limit of the soil for classification purposes

is still 200 cm. In some instances the more weakly cemented

bedrocks (paralithic materials, defined later) and uncemented

bedrocks (some densic materials, defined later) have been

described below the lower boundary of soil and used to

differentiate soil series (series control section, defined in chapter

17). This is permissible even though the paralithic materials

below a paralithic contact are not considered soil in the true

sense. In areas where soil has thin, pedagogically cemented

horizons that are impermeable to roots, the soil extends as

deep as the deepest cemented horizon, but not below 200 cm.

For certain management goals, layers deeper than the lower

boundary of the soil that is classified (200 cm) must also be

described if they affect the content and movement of water and

air or other interpretative concerns.

In the humid tropics, earthy materials may extend to a depth

of many meters with no obvious changes below the upper 1 or

2 m, except for an occasional stone line. In many wet soils,

gleyed soil material may begin a few centimeters below the

surface and, in some areas, continue down for several meters

apparently unchanged with increasing depth. The latter

condition can arise through the gradual filling of a wet basin

in which the A horizon is gradually added to the surface and

becomes gleyed beneath. Finally, the A horizon rests on a thick

mass of gleyed material that may be relatively uniform. In both

of these situations, there is no alternative but to set the lower

limit of soil at the arbitrary limit of 200 cm.

Soil, as defined in this text, does not need to have discernible

genetic horizons, although the presence or absence of genetic

horizons and their nature are of extreme importance in soil

classification. Plants can be grown under glass in pots filled

with earthy materials, such as peat or sand, or even in water.

Under proper conditions all these media are productive for

plants, but they are non soil here in the sense that they cannot

be classified in the same system that is used for the soils of a

survey area, county, or even nation. Plants even grow on trees

or in cracks of exposed bedrock (i.e., rock outcrop), but trees

and rock outcrop are regarded as non soil.

Soil has many temporal properties that fluctuate hourly,

daily, and seasonally. It may be alternately cold, warm, dry,

or moist. Biological activity is slowed or stopped if the soil

becomes too cold or too dry. The soil receives additions of

fresh, undecomposed organic matter when leaves fall or grasses

die. Soil is not static. The pH, soluble salts, amount of organic

matter and carbon-nitrogen ratio, numbers of microorganisms,

soil fauna, temperature, and moisture status all change with

the seasons as well as with more extended periods of time.

Soil must be viewed from both the short-term and long-term

perspective.

An ecosystem does!

Explanation:

An ecosystem holds the others! it includes everything to make a home for organisms

Answer:

1. False

2. True

3. False

4. False

5. False

6. True

Explanation:

1. Remember, the term Genetic diseases implies that they are diseases inherited genetically. Thus, environmental conditions have no direct influence on the spread of genetic diseases.

2. We can make this conclusion because research has shown that genetic disorders are more common in families with one affected member as compared to the general population. In other words, the family's medical history is part of the determinant factor.

3. Some recent studies have shown that both members of identical and fraternal twin pairs do not have the same likelihood of expressing the same genetic disease.

4. Genetic diseases do not occur at the same rate in all human populations.  Researchers often make reference to findings discovered from surviving victims of the Hiroshima nuclear bomb which is said to be the cause of some genetic diseases. Also, the sickle cell genetic disease rate of occurrence is believed to be high in Africa than in North America.

5. Scientists believe that there is no specific age of onset of genetic disease. That is to say, they may appear within an age range but not a specific age.

6. Indeed, many human and animal genetic disorders share similar characteristics . A good example is the albino genetic order in humans has been discovered to share similar characteristics that is found in animals.
