The following statement is true about photosynthesis and cellular respiration: the relationship between them enables life as one knows it to survive, that is the first option.

What are photosynthesis and cellular respiration?

Photosynthesis is the process by which green plants, algae, and some bacteria convert sunlight, water, and carbon dioxide into energy-rich organic compounds, such as glucose, and release oxygen into the atmosphere as a byproduct. During photosynthesis, light energy is absorbed by pigments called chlorophyll, and cellular respiration is the process by which all living organisms, including plants, animals, and humans, convert energy-rich organic compounds, such as glucose, into energy that can be used by the cells. During cellular respiration, glucose and oxygen are broken down in the cells to release energy in the form of adenosine triphosphate (ATP), which is the energy currency of the cells.

Hence, the following statement is true about photosynthesis and cellular respiration: the relationship between them enables life to survive as one know it. That is the first option.

b) Without insulin, what happens to the glucose transporter (GLUT 4) on the cell surface?

Answers

GLUT4 is a glucose transporter protein that is detained intracellularly without insulin in different vesicles that contain proteins such as aminopeptidase.

What is the GLUT4?

It is the skeletal muscle-specific glucose transporter, found mainly in insulin-sensitive tissues, such as muscle and adipocytes.

The lack of insulin affects the migration of Glut-4 towards the plasmatic membrane, being stopped intracellularly in different vesicles and therefore producing a decrease in the transport of glucose into the cell.

Therefore, we can conclude that GLUT4 is a glucose transporter protein that is detained intracellularly without insulin in different vesicles that contain proteins such as aminopeptidase.

Answer:

30 units of energy will be available to primary predators.

Explanation:

Using 10 % law i.e at each step 10 % of energy is transferred to the next trophic level at the rest of either consumed or lost to environment..

so plants have = 3000 units

herbivores = 10% of 3000 = 10/100 × 3000

= 300 units

so primary predators will have = 10% of 300

= 10/100 × 300 = 30 units

What happens when you drink to much salt water

Answers

Answer:

when you drink to much salt water you dehydrate quickly

Explanation:

Consuming very salty water, like the kind in the ocean, may introduce more salt to your body than it's capable of processing. Your body attempts to flush the excess by inducing urination, pushing your kidneys into overdrive. Because you must excrete more water than you consume to get rid of the extra salt, you may dehydrate quickly.
