Which of the following is not a possible effect of rising carbon dioxide levels on plants?a.
increased photosynthesis
b.
increased plant mortality
c.
increased crop productivity
d.
increased plant growth

Answers

Answer 1

Answer: I think the correct answer from the choices listed above is option B. Plant mortality is not a possible effect of rising carbon dioxide levels on plants. This value is a fixed value and cannot be affected by changes in the carbon dioxide level.

Answer 2

Answer:

Answer:

increased plant mortality

Explanation:

The rise of carbon dioxide in the atmosphere will definitely bring about increased in photosynthesis.

Photosynthesis in plants is a process whereby green plant produces nutrient in the present of sunlight from carbon dioxide and water. Photosynthesis is a necessity for plants to supply nutrient to the plants . The chemical equation for photosynthesis can be represented as follows:

6CO2 + 6H2O sunlight → C6H1206 + 6O2

Photosynthesis converts light energy into chemical energy. Green plants in the presence of sunlight uses CO2 and H2O to produce food. Increase carbon dioxide will definitely increase crop productivity and plant growth. The more the carbon dioxide and water in the presence of sunlight nutrient are added to the plant.

Plant will definitely not die because of rise in CO2.

Hormone therapy reduces the interaction of hormones with __________.a. 6y cells
b. antigens
c. vaccines
d. cancer cells

Answers

The answer is d. cancer cells.

In hormone therapy for cancer cells, exogenous hormones are injected. These hormones are called anti-hormones and their purpose is to reduce the interaction of body's hormones with cancer cells. They can reduce the level or inhibit the activity of some hormones that help cancer cells to grow. This way, anti-hormones reduce the ability of cancer cells to use body's hormones and their growth is affected.

Which structural characteristic is seen in RNA but not in DNA? double strands a single strand chains of nucleotides a helical shape

Answers

The structural characteristic seen in RNA but not in DNA is a single strand. RNA and DNA are macromolecules made up of nucleotides organised in chains. DNA has double strands organised in a helical shape. RNA usually consists of a single strand which is not characteristic for DNA.

The answer is single strand

After you eat, insulin is secreted by pancreatic Beta cells into the bloodstream, where it diffuses throughout the body to bind to receptors on target cells, telling them to take up glucose. This mode of signaling is referred to as _____________.

Answers

Endocrine Signaling

Explanation:

Signal from the cells which are distantly located are called Endocrine signals.
This signaling begin from endocrine cells.

These kinds of signals produce a more slow reaction yet have a more drawn out enduring impact. The ligands discharged in endocrine signaling are called hormones, signaling molecules that are delivered in one piece of the body however influence other body areas some distance away.
