What factors determine if a species is fit to survive?

Biology

Answer: variation, reproduction, and heritability.

Explanation:  Genetic variation is an important force in evolution as it allows natural selection to increase or decrease frequency of alleles already in the population. Genetic variation is advantageous to a population because it enables some individuals to adapt to the environment while maintaining the survival of the population.  

All species must reproduce to survive. Organisms cannot live forever, so they must reproduce to allow their species to continue to live on. Reproduction is nature's way of allowing a species to survive.

Higher heritability means the trait evolves faster; fewer generations are required for the trait to increase to the same degree as a trait with lower heritability. For this reason, genetic correlation and heritability show how a trait might change from one generation to the next and into the future.

A specialized structure within a cell that has its own specific function is known as a/an _______.
vichka [17]

Answer:

Organnelle

Ribosomes

Nucleus

Archaeabacteria

Phospholipid bilayer

Lipases

Explanation:

1. Organnelles are specialized structures in a cell designed to perform a particular function that will make the cell normal e.g. ribosome, Chloroplast, mitochondrion are examples of organnelles.

2. The Rough Endoplasmic Reticulum (RER) is one of the two endomembranous systems in the cell. It is characterized by its rough appearance which occurs as a result of ribosomes attached to its surface. This attachment of ribosomes makes its function related to protein synthesis.

3. Nucleus is a membrane bound organnelle found only in EUKARYOTIC cells. It houses the genetic material (DNA) of a cell and acts as the brain by directing all of the cellular activity of that cell.

4. Archaeabacteria is one of the six kingdoms in the hierarchical classification of living organisms. They contain unicellular and prokaryotic organisms that are uniquely characterized by their ability to survive extreme conditions e.g high temperature.

5. The plasma membrane is an outer covering that bounds the cells of both Prokaryotic and eukaryotic organisms. According to the fluid mosaic model that describes the structure of the cell membrane, it contains a phospholipid layer that confines its selective permeability upon it i.e. ability to control what goes in and out of the cell. This is due to the amphipathic nature of the phospholipid i.e. contains an hydrophobic and hydrophilic region.

6. Lipases are enzymes that are involved specifically in the breakdown of lipids and fat molecules into fatty acids and glycerol.
