Answer:

Estrogen.

Explanation:

Plasma membrane is made of lipids and proteins. The lipids are arranged in bilayers and proteins are embedded or may span the lipid bilayer. The carbohydrates are attached on the surface of the membrane.

The molecules that are lipophillic in nature can easily diffuse through the plasma membrane. Among the molecules listed in the question, estrogen is highly lipophillic in nature and can easily cross the lipid bilayer of the plasma membrane.

Thus, the correct answer is option (d).

I will have to use motivation as a way of enhancing change in the life of Sally. From this question, she seems to be a lonely lady, with low self-esteem and no physical activity. The first thing I would do is to help to get her out of monotony by motivating her.

Once motivated, I would help plan her diet and add combinations of physical activities. These activities may include walking and running. With time an expert would take over her physical training.

She has to make time for other activities such as yoga or community work. The purpose for this is so she can meet and connect with other people, this would give her a sense of belonging. And would help boost her self image.

In conclusion, Sally needs a combination of physical and emotional therapy in order to change her lifestyle.

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.
