Biology
1 answer:
Advocard [28]3 years ago
8 0

Answer:

Natural selection needs some starting material, and that starting material is heritable variation. For natural selection to act on a feature, there must already be variation (differences among individuals) for that feature. Also, the differences have to be heritable, determined by the organisms' genes.

Name two factors that confine living things to the biosphere
Ipatiy [6.2K]

Answer:

The two factors are: moderate temperature and energy source.

Explanation:

A biosphere is that portion of the earth where life occurs which means it consists of water, underground, land, and air. On earth, life can be seen at the bottom of the ocean to 9 km above the earth.

The two major factors that confine living thing to the biosphere is the energy source and moderate temperature. Energy is required by all the organisms present on the earth. Every organism has its own way to gain energy like some gain energy from the sun and some from consuming others.

Moderate and constant temperature is important for the survival of the organisms and to maintain homeostasis in them.
