In photosynthetic cells, synthesis of atp by the chemiosmotic mechanism occurs during _________.

1 answer:

5 0

In photosynthetic cells, synthesis of ATP by the chemi-osmotic mechanism occurs during photosynthesis and respiration. Plants can only achieve photosynthesis during the day and then respire during the night because photosynthesis requires the sun's energy to perform the necessary reaction to produce oxygen.

Aleks04 [339]

The abiotic factors of a stream ecosystem involves salt, water, rocks, sediments and trash. This includes the temperature of the water, how much oxygen it contains, how acidic or basic it is, how fast or slowly, and how much sunlight penetrates the surface. A stream ecosystem is the ecosystem of a river viewed as a system operating in its natural environment, including biotic factors and abiotic factors.

Svetradugi [14.3K]

Answer:

1) Wax belong to lipids.

2) <u>Animals</u>: Water and cold isolation and protection from pathogenic microorganisms.

<u>Plants</u>: It controls evaporation and maintains hydration.

Explanation:

1) Wax belong to the biomolecules of lipids.

2) In animals, such as birds, the uropygial gland secrets sebum or wax, spreading it throughout the animal's feathers to prevent water from penetrating as it serves as an isolating compound for animals that live in cold areas. It also provides protection from bacteria and fungi. In coloquial terms, it would be like a water-proof coat that protects them from water and extreme climate.

In plants, the secretion of wax through the cuticle has been developed as an adaptation to control evaporation and maintain hydration.
