Explain why populations tend not to continue to increase exponentially in an environment: 2. Explain what is meant by environmental resistance: 3. (a) Explain what is meant by carrying capacity: (b) Explain the importance of carrying capacity to the growth and maintenance of population numbers: 4. Species that expand into a new area, such as rabbits did in areas of Australia, typically show a period of rapid population growth followed by a slowing of population growth as density dependent factors become more important and the population settles around a level that can be supported by the carrying capacity of the environment. (a) Explain why a newly introduced consumer (e.g. rabbit) would initially exhibit a period of exponential population growth: (b) Describe a likely outcome for a rabbit population after the initial rapid increase had slowed: 5. Describe the effect that introduced grazing species might have on the carrying capacity
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.

Explanation:
In neuroscience, depolarization is an "all or nothing" response; what does that
mean?
The neuron's intracellular charge must get more negative to meet a certain
threshhold in order to depolarize. If the neuron does not hit that threshold, then the
neuron will not fire
The neuron will either accept all signals, or none of the signals received. If the
neuron is ready to receive signals, then it automatically depolarizes and sends the
signals to the next neuron.
The neuron's intracellular charge must get more positive to meet a certain
threshhold in order to depolarize. If the neuron does not hit that threshold, then the
neuron will not fire
The neuron decides how much of the electochemical signals to send to the next
neuron; all or nothing
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.

What molecule was the director of the entire protein building?
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.
What are proteins?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.

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.

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.
