How is an ectotherm most likely to maintain homeostasis during hot weather? O A. By burrowing underground O B. By shivering O C. By sweating O D. By sitting on a warm surface
Answers
An ectotherm is most likely to maintain homeostasis during hot weather by burrowing underground. Thus, the correct option is A.
What is Homeostasis?Homeostasis may be defined as the process that involves a condition of balance among all the body systems required for the body to survive and operate correctly.
Ectotherms are those organisms that can not be able to maintain their internal body temperature with respect to the external one.
They follow different strategies like hibernation during winters and aestivation during summers.
During hot weather, they usually undergo summer sleep by burrowing underground.
Therefore, the correct option for this question is A.

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.

Answers
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.

In the tundra, what is the difference between the biotic and abiotic factors you saw in the image?
Answers
Answer:
Abiotic factors refer to non-living physical and chemical elements in the ecosystem. ... Examples of abiotic factors are water, air, soil, sunlight, and minerals. Biotic factors are living or once-living organisms in the ecosystem. These are obtained from the biosphere and are capable of reproduction.
Explanation:
Biotic is living part whereas abiotic is non-living part of an environment.
The main difference between biotic and abiotic factors is that biotic factors refer to the living part or component of environment such as plants, animals etc whereas abiotic factors refer to non-living part of the environment such as temperature, humidity and light etc. Both biotic and abiotic factors depends on each other for their survival so we can conclude that biotic is living part whereas abiotic is non-living part.

that is what I put
Explanation:
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
Answers
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:
