The answer is 4. Mitochondria
Answer:
A) They have low-maintenance and are easy to keep track of for mutations.
B) The deduction can be "Single Gene Mutation"
Explanation:
After examining the example given in the question on Neurospora crassa and the details about how they reproduce, the following points can be made regarding the questions;
A) It is stated that they form a colony in time and that they are asexual spores and the first reason to choose them would be because they contain somatic cells (which refer to the cells other than reproductive cells) and non-motile gonidia which can multiply by dividing themselves and these properties make the colony's maintenance easy. And since they multiply by division, it is easier to keep track of the occuring mutations.
B) Given the information in the question that the mating is between an albino strain and a wild type, and then between two albino strains which have the same genotype. The results indicate that the strains have gone through single gene mutation during the process.
I hope this answer helps.
Isaac Newton published a comprehensive theory of gravity in 1687. Though others had thought about it before him, Newton was the first to create a theory that applied to all objects, large and small, using mathematics that was ahead of its time.
Explanation:
Renewable and Nonrenewable resources are types of natural resources.
Renewable resources are those resources that can be replaced and renewed naturally such as air, wind whereas nonrenewable resources are those resources that cannot be replaced naturally such as coal, natural gas.
- Human behavior has affected the natural resources and its quality.
- burning of fossil fuels by the human has affected the natural resources by releasing chemicals and toxic substances in the environment.
- Deforestation, land construction and mining activities have disturbed the ecosystem and natural resources.
- A large number of factories and vehicle used by the human has affected the natural resources as it affects the natural quality and increase in the demand for fossil fuels has resulted in depletion of the limited resources.
