Duckweeds will block the sunlight entering the water and thereby decrease the population of submerged plants.
Option B
<h3><u>Explanation:</u></h3>
Duckweeds are a deadly weed that grows on the surface of water bodies like lakes and ponds. The population of these plants increase to a huge extent because of the fertilizers that drain into these water bodies from the nearby agricultural fields.This is called eutrophication.
Now these plants form a layer covering the surface of the water bodies. This leads to blocking the sunlight from entering inside the water. This leads to sunlight deficiency inside the water body. Thus the plants that are growing on the bottom of these water bodies cannot get sunlight and thus dies.
Answer:
e. natural selection
Explanation:
The theory of natural selection was coined by Charles Darwin. It is based on the fitness of certain phenotypes to survive changing environments. The difference in phenotypes arises from mutations in the genome due to pressure from the environment [can refer to the cell, interacting cells, population or ecosystem]. These mutations are heritable and become phenotype traits that are common in a surviving population.
Option A is correct. For skeletal muscle, there are 37 molecules of ATP produced from one Glucose-6-phosphate derived from glycogen, assuming the presence of the glycerol-3-phosphate shuttle.
<h3>How does skeletal muscle use ATP for the duration of exercise?</h3>
1. Contracting skeletal muscle is capable to use a quantity of intra- and extramuscular substrates to generate ATP at some point of exercise. These include creatine phosphate (CP), muscle glycogen, blood-borne glucose, lactate and free fatty acids (FFA), derived from either adipose tissue or intramuscular triglyceride stores.
<h3>What produces the most ATP for muscle contraction?</h3>
Aerobic respiratory produces giant amounts of ATP and is an environment friendly capability of making ATP. Up to 38 ATP molecules can be made for every glucose molecule that is damaged down. It is the desired approach of ATP production by body cells.
