The abiotic factors of a stream ecosystem involves salt, water, rocks, sediments and trash. This includes the temperature of the water, how much oxygen it contains, how acidic or basic it is, how fast or slowly, and how much sunlight penetrates the surface. A stream ecosystem is the ecosystem of a river viewed as a system operating in its natural environment, including biotic factors and abiotic factors.

The structure of a typical antibody molecule

Antibodies are the secreted form of the B-cell receptor. An antibody is identical to the B-cell receptor of the cell that secretes it except for a small portion of the C-terminus of the heavy-chain constant region. In the case of the B-cell receptor the C-terminus is a hydrophobic membrane-anchoring sequence, and in the case of antibody it is a hydrophilic sequence that allows secretion. Since they are soluble, and secreted in large quantities, antibodies are easily obtainable and easily studied. For this reason, most of what we know about the B-cell receptor comes from the study of antibodies.

Antibody molecules are roughly Y-shaped molecules consisting of three equal-sized portions, loosely connected by a flexible tether. Three schematic representations of antibody structure, which has been determined by X-ray crystallography, are shown in Fig. 3.1. The aim of this part of the chapter is to explain how this structure is formed and how it allows antibody molecules to carry out their dual tasks—binding on the one hand to a wide variety of antigens, and on the other hand to a limited number of effector molecules and cells. As we will see, each of these tasks is carried out by separable parts of the molecule. The two arms of the Y end in regions that vary between different antibody molecules, the V regions. These are involved in antigen binding, whereas the stem of the Y, or the C region, is far less variable and is the part that interacts with effector cells and molecules.

If carbon dioxide is completely removed from a plants environment , what would you expect to happen to the plants production of
Zigmanuir [339]
The plant's production of high-energy sugars would reduce significantly. I'm not going to say that the plant would completely stop producing the sugars because it has to respire, and one product of respiration would be carbon dioxide. This carbon dioxide would be recycled so that the plant can photosynthesize and produce sugars.

Which of the following best describes how cleaning products like chlorine, hydrogen peroxide, and soap influence the infectious
torisob [31]

Answer:

These cleaning products break apart the capsules of the viruses causing them to no longer be capable of infecting an individual.

Explanation:

Bleach oxidises organic molecules. This causes proteins to become denatured, or lose their shape. The viral capsule containing the DNA is a coat made up of proteins that is required for the virus to become infectious. Therefore, following bleach treatment, the viral protein capsule become oxidised, cause them to loses their shape, meaning the virus can no longer infect individuals.

Polycystic ovary syndrome is an endocrine disorder and a common cause of chronic anovulation. In addition to the clinical manife
Scilla [17]

Answer:

1. Insulin resistance and diabetes

2. Metformin

Explanation:

Metformin can be used to treat polycystic ovary syndrome, especially for insulin-resistant women (insulin is a hormone that transports sugar into cells).

People with insulin resistance have high levels of this hormone in their blood and excess circulating insulin can aggravate manifestations of polycystic ovary syndrome, and also increase the risk of diabetes.

The main benefits of metformin in the treatment of polycystic ovaries is the normalization of menstrual irregularity and the restoration of ovulatory cycles.

Since most women with polycystic ovary syndrome are insulin resistant, metformin is a good treatment option in some cases.

However, the treatment of polycystic ovary syndrome should be individualized for each woman, depending on the symptoms presented and the goal to be achieved with the treatment.
