In the leaf cells of a plant, enzymes control the rate at which carbon dioxide is converted into glucose. Which environmental factor would MOST affect the action of the enzyme?
Answer: The environmental factor that would most affect the action of enzymes in the conversion of carbon dioxide into glucose (photosynthesis ) is the light.
PHOTOSYNTHESIS - Photosynthesis is a process by which plants and other organisms convert light energy into chemical energy, which is then released to fuel the organism's metabolic activities through cellular respiration. Carbohydrate molecules, such as sugars, store this chemical energy, which is created from carbon dioxide and water.
The first photosynthetic species most likely arose early in the evolution of life and used reducing agents such as hydrogen or hydrogen sulfide as electron sources rather than water. In the process of carbon fixation, carbon dioxide is transformed into sugars; photosynthesis uses energy from the sun to turn carbon dioxide into carbohydrate. Carbon fixation is a redox reaction that is endothermic. Photosynthesis is the oxidation of carbohydrate or other nutrients to carbon dioxide, while cellular respiration is the reduction of carbon dioxide to carbohydrate. Carbohydrates, amino acids, and fatty acids are nutrients involved in cellular respiration.
Overgrazing of land by livestock contributes to a major problem. Which of the following is most directly related to overgrazing
A. depletion of ground water
B. increased pollution
C.erosion of soil
D.acid rain
Overgrazing should be directly related to increased the population when it has the major problem. Hence, the correct answer is option B. increased pollution.
What is overgrazing?It should be arise at the time when the plants should be exposed to intensive grazing for expanding the period of time or it should be without considering the recovery period i.e. enough.
Also, it should be leaded via livestock that should be not managed properly with respect to the agricultural applications, natural reserves.
Hence, the correct answer is option B. increased pollution.

Cells typically respond to DNA damage in three ways: by ceasing to grow and divide until the damage is repaired, by permanently ceasing to grow and divide, or by dying. In 2010 a group of scientists reported that a certain kind of immune reaction can cause DNA damage that leads to a fourth response. DNA damage can turn off genes involved in cell-signaling pathways. Turning off these genes can cause less-mature cells to divide too rapidly, often leading to the development of- a. tumors c. hemophilia b. allergies d. cardiovascular disease
It can lead to the development of A. Tumors
Turning off these genes can cause less-mature cells to divide too rapidly, often leading to the development of (A) tumors.
What is the most common cause of tumor?
When cells reach their end of life cycle or get damaged, they pass away and are replaced by new ones. This normally well-regulated process can, on occasion, become disorganized, allowing aberrant or damaged cells to proliferate and reproduce when they should not. These cells have the potential to develop tumors, which are mass accumulations of tissue.
There are primarily three different kinds of tumors:
Benign: These tumors do not have any cancer-causing properties. They do not penetrate the tissue that is close by and they do not spread to other areas of the body.Tumors that are premalignant have cells that are not currently cancerous but have the capability of developing into cancerous cells in the future.Malignant: Malignant tumors are malignant.Learn more about tumors, here:

Cellular differentiation progressively restricts cell fate because the unexpressed genes in the cell:Select all that apply become more densely packed with nucleosomes accumulate both point mutations and deletions accumulate point mutations undergo irreversible repression accumulate deletions.
Answer:
undergo irreversible repression
Explanation:
Cellular differentiation refers to the process by which one cell and/or cell population divides and differentiates into more specialized cells. During cell fate differentiation, epigenetic marks modify chromatin structure in order to hamper the accessibility of the transcriptional machinery and transcriptional factors to different genes, which are irreversibly repressed. These epigenetic marks include DNA methylation and histone modifications (e.g., histone acetylation, histone methylation, etc). For example, it has been shown that DNA methylation and histone H3 lysine 27 tri‐methylation (H3K27me3) are epigenetic repressive marks on genomic regions that play a major role in gene expression programs during cell fate differentiation.

The chromosomes is divided into small sections called The genes consist of a long strand of The DNA contains the blueprint for how the organism and functions (traits)
Answer:
Traits.
Explanation:
Traits in an organism are controlled by the genes. These genes are made up of DNA that is responsible for the unique appearance of the organisms. Some organisms are different from one another because of the DNA that helps the to perform different functions. In the DNA, all information is present about form and structure of the organisms so that's why we can say that traits or characteristics are controlled by genes.

In a species of Drosophila, developing larva have special proteins in their epithelial cells. These proteins bind to a certain repressor in the larva's cells, which ultimately causes a dark pigment to be produced. What would you expect if scientists purposely injected a developing larva with an excess of these proteins?
Answer:
The larva gets dark pigment.
Explanation:
If scientists purposely injected an excess concentration of these proteins in the larva, the larva gets deep dark colour because this protein is responsible for the pigment colour in the larva of Drosophila. By increasing the protein concentration the pigment will also have a very dark colour. So we can conclude from this that increasing the amount of protein causes increase in the pigment colour.

Answer:

Explanation:
have you pooped today?
The option which describes the function of RNA polymerase is that it forms an RNA strand using a DNA strand as a template. Thus, the correct option for this question is D.
What is RNA polymerase?RNA polymerase may be defined as a multi-unit enzyme that synthesizes RNA molecules from a template of DNA through a process called transcription. This enzyme is responsible for copying a DNA sequence into an RNA sequence, during the process of transcription.
RNA polymerase binds to DNA, separates the strands, then uses one of the strands as a template from which to assemble nucleotides into a complementary RNA strand.
It uses a single-stranded DNA template to synthesize a complementary strand of RNA. Specifically, RNA polymerase builds an RNA strand in the 5' to 3' direction, adding each new nucleotide to the 3' end of the strand.
Therefore, the option which describes the function of RNA polymerase is that it forms an RNA strand using a DNA strand as a template. Thus, the correct option for this question is D.
