Scientist claims that Elysia chlorotica, a species of Sea slug, is capable of photosynthesis. which of the following observation
joja [24]

Answer:

The correct answer is - B) Elysia Chlorotica grows when exposed to light in the absence of other food sources

Explanation:

If placing Elysia Chlorotica in presence of the food sources in the presence or absence of light it still grows as normal. However, if placing in the light in absence of the food sources it should not grow if it is not able to perform photosynthesis but it does which means there is a photosynthesis process also involve in the Elysia.

Photosynthesis is the process that involves the production of energy and nutrition in presence of light with water and atmospheric carbon dioxide.

How do substrate concentration and pH affect enzyme-controlled reactions
Dima020 [189]
For example, pH can have an effect of the state of ionization of acidic or basic amino acids. Acidic amino acids have carboxyl functional groups in their side chains. Basic amino acids have amine functional groups in their side chains. If the state of ionization of amino acids in a protein is altered then the ionic bonds that help to determine the 3-D shape of the protein can be altered. This can lead to altered protein recognition or an enzyme might become inactive.

Changes in pH may not only affect the shape of an enzyme but it may also change the shape or charge properties of the substrate so that either the substrate connot bind to the active site or it cannot undergo catalysis.

In geneal enzyme have a pH optimum. However the optimum is not the same for each enzyme.

Which of these statements about trophoblast is false?
lukranit [14]

Answer:

The statement C that says ''is derived from the inner cell mass'' is false.

Explanation:

The trophoblast is a structure composed of a set of cells (cytotrophoblast and syncytiotrophoblast), which are shaping the outer layer surrounding a blastocyst, during the earliest stages of embryonic development that mammals pass.

The trophoblast provides nutritive molecules to the developing embryo and facilitates its implantation to the uterine wall due to its ability to erode the tissues of the uterus, that is, it is responsible for making it possible for the embryo to be implanted in the uterine endometrium. Thus, the blast can join the cavity formed by the uterine wall, where it will absorb nutrients from the fluid from the mother.

During the third week, embryonic development includes the development of the trophoblast. At the beginning, the primary villi are formed by the internal cytotrophoblast which is surrounded by the outer layer of syncytiotrophoblast. Then, the cells found in the embryonic mesoderm are directed to the primary villous in the third week of gestation and when it ends, the mesodermal cells begin to be singled out to form blood vessel cells.
