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.

Explanation:
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.

Considering the Principles of Trace Evidence, what would investigators be looking for to prove that someone entered from outside the facility?
Muddy or wet footprints in the carpet

O AO BO
The Punnett square shows that 50% of their children will have the AO genotype and 50% will have the BO genotype. Neither of these genotypes give the child type O blood, so it is impossible for the child to have type O blood. The child would need two O alleles.

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.
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:

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.

Answer:
1. Mitotic cell division
Explanation:
Embryonic development is the formation of organisms that starts from the process of fertilization. The stages of development represent mitosis.
What is mitosis?Mitosis is a part of the cell cycle, that produces two identical nuclei and daughter cells from the division of the cell and replication of the parent cell.
From the diploid parent cell, two diploid daughter cells are produced in mitosis. This process is the first and the initial stage of embryonic development that initiates the growth and development of the embryo from the parent cell.
Therefore, option 1. mitosis is the process of embryonic development.

Marianne is conducting an experiment on homeostasis in paramecium which is a type of single celled organism. Which of these observation
Answer:
Contractile vacuole is responsible for maintaining the homeostasis in paramecium.
Explanation:
The observation of this experiment is that contractile vacuole is responsible for maintaining the homeostasis in paramecium because the contractile vacuole regulates the quantity of water inside a cell. Contractile vacuole controls the water balance in the body by absorbing and removing the excess amount of water out of the cell. This function of contractile vacuole allows the cells to survive under hypotonic stress that is present in the pond water or any other stressful environment.
