Answer:
Explanation:
Hardy weinberg principle state that in a large random mating population in the absence of migration,mutation and selection the gene frequency remain at equilibrium.
The frequency of allele A and A will remain constant from generation to generation if hardy weinberg principle is in place.
2. Random mating- The population must have equal chance of been mated to by any member of the population.
Answer:
Viruses replicate only inside host cells.
Explanation:
<u>Viruses are not used as evidence to support the cell theory because they are not considered a cell and cannot carry out vital life processes without getting into host cells. </u>
According to the cell theory, the cell is the basic unit of life, all living organisms are made up of cells and cells arose from preexisting cells. A virus that is not in a host cell is just a piece of DNA/RNA surrounded by a protein coat and is not capable of carrying out any life process for it to be considered living.
<em>Viruses are only able to reproduce and multiply when they get access to a living host. They use the genetic mechanisms of the host to replicate their DNA/RNA using the lytic or lysogenic cycle. Hence, they are not used to support the cell theory. </em>
Evolution means that populations of organisms change over time.
Explanation:
Evolution refers to the phenomena by which a population develops new traits and becomes more and more fit to survive in a given environment.
Evolution can be studied in two different ways- as a pattern of evolutionary changes and as a process of evolution.
Study of Evolution help us to understand the history of life.
Evidences of evolution support the view that species evolved from common ancestors rather than created separately..
These evidences are contributions of various fields of biology and geology.
This is an example of an experiment because a scientific procedure undertaken to make a discovery, test a hypothesis, or demonstrate a known fact is an experiment. She is investigating the movement and analogy between the earthworm using the box and flashlight.
Answer:
Explained
Explanation:
Due to lack of of Triose phosphate isomerase cell will be unable to interconvert Dihydroxyacetone to glyceraldehyde 3 phosphate.
And the cells will be able to complete the glycolysis only in the presence of glyceraldehyde 3 phosphate which will generate 2 ATP and hence the net ATP gain during whole process in anaerobic condition will be Zero. This will lead to the dath of the mutant yeast.
a) While in case of aerobic condition, only one molecule of pyruvate will also be able to produce more ATP compared to anaerobic condition by further oxidation which is sufficient for yeast to survive.
b) the cells will be able to complete the glycolysis only in the presence of glyceraldehyde 3 phosphate which will generate 2 ATP and hence the net ATP gain during whole process in anaerobic condition will be Zero. This will lead to the death of the mutant yeast.
