In cells such as animal cells that lack cell walls, cytokinesis follows the onset of anaphase. A contractile ring composed of actin filaments forms just inside the plasma membrane at the former metaphase plate. The actin filaments pull the equator of the cell inward, forming a fissure. This fissure, or “crack,” is called the cleavage furrow. The furrow deepens as the actin ring contracts, and eventually the membrane is cleaved in two (Figure 1).

Suppose your friend investigated the color of pea pods and concluded that green pods (G) were dominant over yellow pods (g). What experimental evidence would be needed to support this conclusion?
Answers
This information can be confirmed by obtaining the observed phenotypic frequency in the second generation (F2) of a genetic cross between pure lines.
The observed phenotypic frequency is the number of individuals that have a specific observable trait (in this case, green pods or yellow pods).A dominant trait produces a 3:1 phenotypic rate in the second generation (F2) of a genetic cross between two pure lines.In conclusion, this information can be confirmed by obtaining the observed phenotypic frequency in the second generation (F2) of a genetic cross between pure lines..

A single-celled organism can be a living organism. In the single-celled organisms, all the functions are performed by a single cell. Thus, the given statement is true.
What are the single-celled organisms?A unicellular organism is also known as a single-celled organism. The unicellular organism is an organism which consists of a single cell only, unlike the multicellular organism which consists of multiple cells and tissues. These organisms fall into two major categories, which are the prokaryotic organisms and the eukaryotic organisms.
The two categories of organisms are classified on the basis of the membrane-bound organelles and a well-defined nucleus present in the cell. Some examples of the single-celled organisms include Escherichia coli, Diatoms, Protozoa, Protista, Pneumococci, and Dinoflagellates.

What is Sickle cell anemia?
Sickle cell anemia is a hereditary disease which provides less oxygen to cells due to a change in the shape of red blood cells which fails to carry oxygen to cells.
In sickle cell anemia, the effected or mutated part is the beta gene that normally makes hemoglobin but due to the mutation in the amino acid, the protein formed is defected and fails to perform its normal function.
As mentioned above, it is a heredity diseases and pass from generations to generations.If Mary has a child with someone who does not have a mutated sickle cell allele, there is a 25% probability that the child will be a carrier.
Therefore, The statement is true about Mary is If Mary has a child with someone who has sickle cell disease, there is a 50% probability their child would have the disease. Thus, option A is correct.

Regulation of body temperature in humans is most closely associated with the
A) production of gametes
B) evaporation of sweat
C) absorption of carbon dioxide
D) production of hydrolytic enzymes
Answers
Answer:
b
Explanation:
Regulation of body temperature in humans is most closely associated with the evaporation of sweat that is present in option B, as the higher the body temperature, the more sweat is needed to maintain homeostasis.
What is the need for homeostasis in the body?The body maintains a particular internal temperature irrespective of changes in the external environment, and this is possible because of the homeostasis in the body, which is important because many of the body's processes are temperature and pH sensitive, such as the enzymatic function, the alkalinity of blood, etc.
Hence, regulation of body temperature in humans is most closely associated with the evaporation of sweat that is present in option B, as the higher the body temperature, the more sweat is needed to maintain homeostasis.

Use the model here to describe the transfer of matter and flow of energy from one trophic level to another within an ecosystem.
Answers
Answer:
Thanks to light energy or chemical energy, the producers, which are on the base of the pyramid, produce their food. Then, the primary consumers eat the producers. The secondary consumers eat the primary consumers. Lastly, the tertiary consumers eat the secondary consumers. The producers process the residues from all the levels obtaining their food and starting the cycle again. Each level in the pyramid has the matter that the animals in the next level will consume. The animals digest the food and break it down into small components that the body uses as energy and for its structure.
The flow of energy from one level to the other is not efficient. Part of it is lost as heat or due to not good digestion. As a result, the energy transferring as we ascend in the pyramid is lower, making it impossible to continue the pyramid since there is not enough energy to nourish another level.
Explanation:
There is a loss of matter from one level to another since some are lost as fecal matter because it could not be processed. The same process happens with the energy from one level to the other. The energy decreases since a part is lost as heat, and the animal uses a part of it to stay alive. As a consequence of this decrease in energy, the higher levels receive less energy than the ones in the lower part of the pyramid.
The flow of energy from one trophic level to another within an ecosystem. Part of it is lost as heat or due to not good digestion.

Which health factor is an individual unable to change?
A-nutrition
B-environment
C-inherited genes
D-cholesterol levels
Answers
Answer:
C-inherited genes
Explanation:
The health factor that an individual is unable to change is inherited genes, which is in Option C, as inherited genes are passed down from parents to their offspring and can influence an individual's health.
What are inherited genes?Inherited genes are a fundamental aspect of an individual's biology that they are born with and cannot change. These genes provide the blueprint for the development and functioning of various systems in the body, including the immune system, cardiovascular system, and nervous system. Some genetic traits can increase an individual's risk of developing certain diseases or conditions, while others may protect against certain health problems. While individuals cannot change their inherited genes, they can take steps to manage their health based on their genetic risk factors.
Hence, a health factor that an individual is unable to change is inherited genes, which is in Option C.
