Grapes growing on a vine are observed to shrink slightly during the day and increase in size at night. This is because: a. developing fruits, such as grapes, transpire a lot of water to stay cool. b. photosynthesis to produce sugar occurs in the light, but respiration and, therefore, the growth of new cells occurs mostly in the dark. c. in leaves, phloem flow to growing sinks only occurs when the stomata are closed, because the transport capacity of the xylem is too small to supply water for both transpiration and phloem flow. d. during the day, transpiration pulls on the water in the whole plant, causing the grapes to shrink slightly.

Consider the food chain grass → grasshopper → mouse → snake → hawk. How much of the chemical energy fixed by photosynthesis of the grass (100%) is available to the hawk?

Answers

Answer:

0.01%

Explanation:

According to the ten percent rule of energy transfer, whenever energy is transferred from one trophic level to a higher trophic level only 10% of total energy available at the lower level gets transferred to a higher one.

Therefore, when the energy is transferred along with the food chain:

grass → grasshopper → mouse → snake → hawk, from grass to hawk there is a loss of 10% of energy at each level.

Therefore, the hawk only gets 0.01% of the energy from the grass.

Answer:

The best answer is Grass. The grass is photosynthetic, which means grasses make their energy from the sun. About 10% of this total energy is available to other organisms in the food chain.

Explanation:

Glucose is stored as which molecule within the liver and skeletal muscle tissue? a. Starch
b. Phospholipids
c. Glycogen
d. Glucagon

Answers

Answer:

C. Glycogen

Explanation:

When the food made of carbohydrates is broken in the organism, it creates glucose, which is a type of sugar that the body uses as a form of energy. The amount that is not used gets stored in various tissues of the body, but the places where the glycogen is stored in larger amounts are the liver and skeletal muscle.

Answer:

Glycogen

Explanation:

Glucose is used primarily as a source of energy and as such it has to go inside the cell. Excess glucose that is not immediately needed as a source of energy is combined into long strands of clucose units called glycogen and it is stored in the liver and skeletal muscle tissue. Glycogen is later broken dowin into its constituent glucose units and used as a source of energy when needed.
