Answer;
-Allele frequencies
The hardy-weinberg principle states that allele frequencies in a population do not change unless outside factors affect the gene pool.
Explanation;
Hardy-Weinberg principle is a mathematical model that describes how genotype frequencies are established in sexually reproducing organisms.
The Hardy-Weinberg equilibrium is a principle stating that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors. The Hardy-Weinberg equilibrium can be disturbed by a number of forces, including mutations, natural selection, nonrandom mating, genetic drift, and gene flow.
It is A. meiosis im pretty sure :)
Explanation: Survivorship curves fit three types. A Type I curve shows a low death rate in early and middle life but the death rate increases steeply in old age. A Type II curve shows a death rate is more constant throughout the lifetime of the species.
Answer:
B) a nonsense mutation; this is because a nonsense mutation results in the change of a regular amino acid codon into a stop codon, which ceases translation. This fits with the problem's description of the protein that causes the symptoms as too short, as translation is the process by which proteins/polypeptides are created. A missense mutation would not be the answer because it still codes for an amino acid, which would not shorten the protein. A duplication of the gene would probably just lengthen the protein or not affect its length at all.
Answer:
A. is palisade mesophyll
B. is spongy mesophyll
EXPLANATION OF PALISADE MESOPHYLL
- Palisade cells are found in the mesophyll of a leaf and their main function is the absorption of light so that photosynthesis can take place.
- The palisade mesophyll consists of chloroplasts with chlorophyll that absorb the light energy
- The mesophyll layer is made up of the palisade cell and spongy parts. #answerwithquality #BAL
