Answer:

Photosynthesis.

Explanation:

Endosymbiotic theory may be defined as the theory that explain the evolution of the chloroplast and the mitochondria. The chloroplast is limited to the plant cells only.

The development of chloroplast proves to be beneficial for the plant cells. This makes the plant cells, autotrophic organism. The main site of the photosynthesis is chloroplast in plant cells. Chloroplast helps in the capture of sunlight and convert into the chemical energy.

Thus, the correct answer is option (B).

As a character of all living things, homeostasis relates most directly to which of the following biological themes
Novosadov [1.4K]

Explanation:

As a characteristic of all living things, homeostasis relates most directly to which of the following biological themes?

A.) Interacting systems.

B.) Stability.

C.) Evolution.

D.) Scale and structure.

Correct: B.) Stability.

During homeostasis the body maintains a constant internal balance (stability) in pH, temperature, blood pressure etc. Cells in a multicellular organism become specialized for particular tasks and communicate with one another in order to maintain homeostasis.

Within the human body these are known as hormone cascades, where several complex steps occur- the tissues signal to one another with the use of hormones released by the endocrine system. The regulation (increase and decrease) of these secretions is achieved by negative feedback loops, where the release of certain substances during a cascade in turn halts the secretion of hormones at earlier stages.

In 1998, scientists discovered that the expansion of the universe has been accelerating.
KengaRu [80]

Answer:

Option A (dark energy) is the right answer.

Explanation:

  • A hypothetical supplier of power that creates a force that contradicts gravity, which is assumed to have been the catalyst of accelerated universe development.
  • Hypothetically, dark energy counteracts the kinetic energy including its beginning of the globe, meaning that perhaps the multiverse does not have intrinsic curvature, although observational measurements presently indicate.

Some other three choices have no relation to the particular situation. Thus option A would be the right solution.
