Write your question here (Keep it simple and clear to get the best answer). Define the tearm physicology?
Correct question: Write your question here (Keep it simple and clear to get the best answer). Define the term physiology?
Answer: physiology is the study of how the systems of the body works, and the ways in which their integrated cooperation maintains life and health of the individual.
Explanation:
The goal of physiology is to explain the physical and chemical factors that are responsible for the origin, development and progression of life. Each type of life, from the simple virus to the largest tree or the complicated human being, has its own functional characteristics.
In the study of the human physiology, we attempt to explain the specific characteristics and mechanisms of the human body that make it a living being. The very fact that we remain alive is almost beyond our control, for hunger makes us seek food and dear makes us seek refuge. Sensation of cold make us look for warmth.
Therefore in a simple term, PHYSIOLOGY is the study of how the systems of the body works, and the ways in which their integrated cooperation maintains life and health of the individual.
How does Genetic Variation relate to Selection?
Genetic variation is a measure of the genetic differences that exist within a population. Genetic variation is essential for natural selection because natural selection can only increase or decrease frequency of alleles that already exist in the population. Genetic variation is caused by: mutation.
Answer: Genetic variation is important to the processes of natural selection and biological evolution. The genetic variations that arise in a population happen by chance, but the process of natural selection does not. Natural selection is the result of the interactions between genetic variations in a population and the environment.
What will happen to the speed of a wagon rolling to the right if the direction of the net force is in the opposite direction to the left?
Answer:
the speed of a wagon rolling to the right if the direction of the net force is in the opposite direction to the left would decrease the speed of the wagon
Explanation:
Answer:
The wagon's speed increases to the left. ... The acceleration of an object moving along a curved path is constantly changing even if the speed is constant, because the direction of the object constantly changes.

d) Polar bonds
What sort of evidence would support at least one of the components of cell theory ? a Rocks and other non-living things are not composed of cells b A microscope is necessary to make observations of nearly all cells c Cells are observed converting one form of energy into another d The origin of all cells can be traced to previous or pre existing cells
Answer:
D
Explanation:
The correct answer would be that the origin of all cells can be traced to previous or pre-existing cells.
According to the cell theory which is made up of three parts;
The cell represents the basic unit of all life.All living organisms are made up of cells.Cells do not arise spontaneously, but only from pre-existing cells.Hence, the discovery that the origin of all cells is traceable to previously existing cells supports the latter part of the cell theory.
The correct option is, therefore, D.

How does the size of the soil particles impact
the soil's permeability (movement of water)?
Answer:
Water moves by gravity into the open pore spaces in the soil, and the size of the soil particles and their spacing determines how much water can flow in. Wide pore spacing at the soil surface increases the rate of water infiltration, so coarse soils have a higher infiltration rate than fine soils.
How does soil particle size affect permeability?
But permeability is a different thing. It increases as particle size increases. By definition, permeability is a MEASURE OF EASE with which fluids will flow though a porous rock, soil or sediment. ... That means capillarity increase as particle sizes decreases.
When organisms
they increase in size.
Answer:
The increase in size and changes in shape of a developing organism depend on the increase in the number and size of cells that make up the individual. Increase in cell number occurs by a precise cellular reproductive mechanism called mitosis.
Explanation:
define and understand the following terms:(1)Phylum (2)Class (3)Family (4)Order (5)Genus
Explanation:
phyllum: group group of related classes
classes: group of related order
family: a group of related genera (genus)
order: group of related families
genus: group of related species
Answer:
(i) Phylum
The phylum is second highest unit of classification after Kingdom. It includes one or more related classes of animals. In plants, instead of phylum, the term ‘division’ is used.
(ii) Class
The class is a taxonomic group consisting of one or more related orders. For example, the class, Mammalia, includes many orders like Primata (Man), Carnivora (tiger) etc.
(iii) Family
Family is a taxonomic group containing one or more related genera, eg., Family hominidae contains apes, monkeys and man. In plants, families are categorized on the basis of vegetative and reproductive features.
(iv) Order
Order is a taxonomic group containing one or more families. For example, the order, carnivora, includes many families.
(v) Genus
Genus is a taxonomic group including closely related species. For example, the genus, Solanum, includes many species such as nigrum, melongena, tuberosum, etc.

Answer:
The mushroom is composed of two parts, the above ground part, and the underground part. Each part has its unique function and purpose in the life cycle of a mushroom.
Spores
It is usually released into the air and falls on the ground to start the life cycle of the mushroom. Seeds that acts as the mushrooms reproductive system.
Stem
A soft branch is supporting the mushroom’s cap.
Gill
Located under the cap, it produces the spore of the mushroom.
Mycelium
This part of the mushroom serves as the breeding ground of smaller mushrooms to grow.
Hypha
The microscopic filament that draws water and the organic matter necessary for mushroom development.
Volva
The remnant of a membrane that completely covers the immature mushroom.
Ring
A covering located under the cap surrounding the stem.
Cap
The upper part of the mushroom that protects the gills. It usually resembles a headdress, hence its name.

Please Helppp!!! What could lead to different populations of the same species living in different environments?
Answer: Migration, because species move to other places for food or a better or more suitable habitat and sometimes their is other species there.
Different ecological and biogeographical causes lead to different populations of the same species living in different environments. Ecological factors include intraspecific competition, migration, resource searching, habitat destruction, among others. Biogeographical dispersion involves wider areas and time factor. Human action is also a cause of dispersion.
-----------------------------------
Dispersion can be defined as the dissemination and distancing process of some individuals from others. It refers to the change in an organism's range or distribution area.
Different ecological and biogeographical processes might be involved in organisms' dispersion.
Ecological processes involve intraspecific competition for resources, habitat destruction, lack of resources -food or water-, among others. This is an intra-area, moderate dispersion that reduces competition and increases niche findings. It involves daily and seasonal migration and territoriality. Biogeographical processes refer to bigger changes that involve wider areas and time. It includes the historical factor, besides migration. This is an extra-area dispersion process.→ Jumping dispersion refers to a few individuals, in a short time, that can cross a barrier and occupy a new area. In this situation, the establishment is not always for sure. They must reproduce and start a new population of a certain size that can survive the new conditions.
→ Diffusion refers to populations that, through many generations, explores and expands in new regions with favorable conditions.
→ Secular migration is the diffusion through thousands of generations.
Dispersion is also caused by human actions, following different interests and goals.When two populations of the same species migrate to new areas and adapt to different environmental pressures, they will probably suffer from the speciation process with time, becoming two different species.

B cells can divide to form plasma cells. Each plasma cell contains many mitochondria
and an extensive endoplasmic reticulum. Referring to the function of plasma cells in your answer, explain why these features are important adaptations.
Answer:
Explanation:
The presence of mitochondria and an extensive endoplasmic reticulum are the features that are important for adaptations of the plasma cell because plasma cells (white blood cells) secrete immune proteins also called antibodies which only formed due to the presence of endoplasmic reticulum whose function is to formed proteins for the cell so that's why plasma cells have large sized endoplasmic reticulum.

Protein are digested and transported by fellow protein. Give vivid examples to support the statement
Answer and Explanation:
The transport and digestion of proteins is done by other proteins called enzymes. An example of this occurs in the biochemical digestion of proteins, where the enzyme pepsin promotes digestion, the breakdown of proteins into smaller pieces, through hydrolysis which is the breakdown of molecules with the use of water. These pieces of the protein are transported to the duodenum where they are digested again by the enzyme enterokinase.

in which Domain & Kingdom would scientists classify an organism, whose cells contain a nucleus, has cell walls made of chitin, and does not have chloroplasts?
Answer:
The correct answer is -
Domain: eukarya
kingdom: fungi
Explanation:
A cell with a nucleus and cell wall made up of the chitin and does not have chloroplast, are all the characteristic features of an organism of kingdom fungi which is a group of eukaryotic organisms.
The cells with the nucleus are grouped in the domain eukarya while the prokaryotic organism does not carry a nucleus in their cell and divided into Archaea and bacteria. The chitinous cell wall without any chloroplast in the cell is one of determining features of the fungi kingdom.
You do a serial dilution in the same manner as the one in the video. A plate with a sample volume of 10-6 mL produced 43 colonies. What was the original cell density (CFU)?
Answer: 43 x 10^6 CFU.
Explanation:
Plate count is a method used to determine the number of viable microorganisms in a sample. When the bacterial concentration is high, serial dilutions are carried out in a 1:10 sequence. Then, the dilutions are successive dilutions keeping the dilution factor constant at each step. Small aliquots of these dilutions are seeded in medium contained in a Petri dish where the bacteria grow forming colonies. Then the plates are incubated and colonies develop both within the agar and on the surface.
If the concentration of the seeded aliquot is too high, the bacteria will grow too much and it will not be possible to distinguish the colonies. However, if the concentration is very low, the number of colony forming units (CFU) may be very low and thus can be counted.
Colony forming units are calculated:
CFU = Number of colonies / (volume seeded on the plate * dilution).
The dilution is 10^-6, the number of colonies counted is 43, and usually the volume plated is 0.1 mL, so we replace that in the equation:
CFU= 43 / (0.1 mL * 10^-6)
CFU= 43000000 = 43 x 10^6
