Answer:

he relationship between environment, variation and selection lay the foundation for natural selection and evolution.

Genetic variations are present among species due to number of reasons like recombination or crossing over during meiosis, mutations, random fertilization etc. These factors bring changes among the members of a species. Some of the species become better adapted to survive in a particular environment whereas some are not better adapted and become extinct over a period of time. The environment selects the organisms that are best adapted to survive and hence lead to variations.

4. Describe the cell cycle and cell division and explain their importance to an organism.

Marianna [84]

The main reasons why cell division is important in organisms are reproduction, repair and growth. Cell division is necessary in order for life to continue.

The length of the cell cycle is important because it determines how quickly an organism can multiply. For single-celled organisms, this rate determines how quickly the organism can reproduce new, independent organisms. Most of the differences in cell cycle duration between species and cells are found in the duration of specific cell cycle phases. DNA replication, for example, generally proceeds faster the simpler the organisms. One reason for this trend is simply that prokaryotic have smaller genomes and not as much DNA to be replicated.

Two principal types of connective tissue in a muscle are

Nesterboy [21]

Answer:

Connective tissue that are found in muscle are of 3 types-Endomysium,Perimysium and epimysium.

Explanation:

Endomysium is called as areolar connective tissue that have nerve and capillaries.

It attaches with epimysium and perimysium and form collagen fibers of tendons.

Perimysium is a sheath of connective tissue that transmit lateral contractile movement.

Epimysium is the layer that is formed by irregular connective tissue .

This layer covers the muscle and provide protection from friction against muscle and bone.

This layer contain fascia and other connective tissue.
