Answer:

Gas exchange is the physical process by which gases move passively by diffusion across a surface. For example, this surface might be the air/water interface of a water body, the surface of a gas

Gas exchange is the process of absorbing inhaled atmospheric oxygen molecules into the bloodstream and offloading carbon dioxide from the bloodstream into the atmosphere. This process is completed in the lungs through the diffusion of gases from areas of high concentration to areas of low concentration.

Describe how C. parvum obtains the glucose it needs for glycolysis after it has infected another cell. Explain the role of lacta
ch4aika [34]

Answer:

C. parvum takes energy from glucose which is present in the digestive tract after the process of glycolysis.

Lactate dehydrogenase which is responsible for the conversion of lactate into pyruvate molecule.

Explanation:

C. parvum is a protozoa that lives as a parasite in the digestive tract of animals. They take nutrients from the cell which are present in the form of glucose. C. parvum uses a specific type of enzyme i. e. lactate dehydrogenase which is responsible for the conversion of lactate into pyruvate and also helps in the production of ATP through glycolysis process. In this process, the glucose molecule is broken down into two molecules of pyruvate, two molecules of ATP, two molecules of NADH, and two molecules of water. So C. parvum takes ATP from that way from the host cells.

Which of the following are examples of positive feedback loops? (Choose all that apply)
aleksley [76]

The examples of positive feedback loops are as follows:

  1. contractions during the process of giving birth
  2. Blood clotting

<h3>WHAT IS POSITIVE FEEDBACK LOOP:</h3>
  • Positive feedback loop is that in which a change in a given direction causes additional change in that same direction.

  • The contractions during the process of giving birth is an example of positive feedback loop because the contractions further stretch the walls and continues until birthing occurs.

  • Also, the clotting of blood causes the stoppage of blood flow.

Therefore, the examples of positive feedback loops are as follows:

  1. contractions during the process of giving birth
  2. Blood clotting

How many sperm cells are formed from an original cell in a Drosophila fruit fly at the conclusion of meiosis?
julsineya [31]

Answer:

C. Four Haploid Sperm Cells

Explanation:

Meiosis is a cell division measure that creates four haploid cells (gametes) from a solitary diploid germline cell. In males, meiosis is essential for spermatogenesis, the cycle to produce sperm. Sperm are the haploid cells that are produced in meiosis.  

Meiosis is a profoundly moderated cell division measure in eukaryotes that produces 4 cells (gametes) from a solitary cell (mother). Nonetheless, Nondisjunction in the male of Drosophila causes much of the time sperm with an addition or loss of chromosomes.
