In an experiment two potted plants, labeled Plant 1 and Plant 2, are placed in transparent plastic bags and left in the open. So

dium hydrogen carbonate is added to the bag covering Plant 1. This compound decomposes slowly to produce carbon dioxide. Soda lime is added to the bag covering Plant 2. This compound absorbs carbon dioxide. Both plants are watered regularly with the same amount of water. After several days, starch test results indicate starch in leaf 1 but an absence of starch in leaf 2.
This experimental data confirms the _________________________
A) role of water in photosynthesis.
B) role of sunlight in photosynthesis.
C) role of nutrients in photosynthesis.
D) role of carbon dioxide in photosynthesis.

Phoenix [80]

Allergic responses to inhaled antigens occur when an individual is first sensitized to the antigen (i.e., the allergen), inducing an immune response and then has a subsequent exposure to the same antigen. The sensitization phase is characterized by <u>Induction of a CD4 T cell type II immune response</u>.

The process by which your body becomes sensitive to a particular substance is called sensitization. When your immune system becomes sensitized to an allergen, you can develop certain symptoms.

Antigens that can induce an allergic response are called allergens, and they are often derived from non-infectious or non-microbial sources.

Human and sperm whale myoglobin have very similar primary structures. Which of the following statements are correct? a. The two
Mandarinka [93]

Question is incomplete ,complete question is as follows :

Human and sperm whale myoglobin have very similar primary structures. Which of the following statements are correct?

1) The two proteins are very likely related evolutionarily.

2) The differences in the sequences in many instances represent a conservative change (such L for I).

3) The differences in the sequences in many instances represent a nonconservative change (such as D for A).

4) There is no correlation between the two proteins since they originate from very different species.

Human and sperm whale myoglobin have very similar primary structures. Which of the following statements are correct?

A) Statements 1 and 2 are correct.

B) Statements 1, 2, and 4 are correct.

C) Statements 1, 2, and 3 are correct.

D) All of the listed statements are correct.

Answer:

A) Statements 1 and 2 are correct.

Explanation:

As the Human and sperm whale myoglobin  are very likely related evolutionarily hence option a is correct.

The differences in the sequences in many instances represent a conservative change (such as L for I) hence option b is also correct.

While all the other options are not correct.
