Answer:
a. most genes encode one polypeptide and can be operationally defined by the complementation test
Explanation:
Genes are the stretch of DNA that code for specific polypeptides. In general, one gene codes for the only polypeptide.
Genes are defined by complementation tests which in turn tell if two mutations have occurred in the alleles of the same gene or different gene.
For the purpose, an organism with the homozygous genotype for one recessive mutation is crossed with an organism having the homozygous recessive genotype for another mutation.
If the two mutations are in the same gene, the progeny would show the mutant phenotype. On the other hand, if two mutations are in different genes, the progeny would exhibit normal phenotype.
Answer:
Yes, it is usually an inherited trait
Explanation:
Answer:
D:) sunlight
Explanation:
Sunlight is one of the resources that are available in limited quantity in water bodies as compared to the land habitats since sunlight can penetrate up to a certain depth in water. However, land habitats have ample of sunlight available for plants. During early colonization of land habitats, dense forests were not present on land which in turn made even more sunlight available to the land plants of all height. Sunlight is one of the required factors to support plant growth and development.
Answer:
Anaphase of meiosis II
Explanation:
During Anaphase II, the spindle fibers pull the sister chromatids apart, toward the opposite poles of the cell. I recommend searching Anaphase II up and looking at a picture. It will give you a better visual understanding.
I think the answer is, Echocardiograph :)
