The answer in here is Na+. We know this because <span>a cell membrane is non-polar which means that polar molecules or charged particles (ions) will not be able to go through without a channel. Likewise, small non-polar molecules will be able to diffuse without a channel - straight through the membrane. That is why the best option is Na+</span>

Agata [3.3K]

Answer:

The question is incomplete, it lacks the main questions, those questions are:

a. What is the genotype for black chickens?

b. What is the genotype for white chickens?

c. What is the genotype for erminette chickens?

Explanation:

This question involves a gene coding for feather colour in some birds, in which the black allele (B) and white allele (W) is involved. According to the question, the gene coding for feather colour exhibits co-dominance i.e. both the black (B) and white (W) allele are expressed in a heterozygous state (BW) to form an erminette phenotype.

Hence, if the neither alleles is dominant or recessive over the other. The black phenotype will only be expressed when the genotype is BB.

The white phenotype will only be expressed when the genotype is WW

The combination of both alleles which results in the simultaneous expression of both in the erminette phenotype, will be BW genotype.

Question 1 (Multiple Choice)
choli [55]
1. A forensic pathologist would most likely perform a forensic autospy. Forensic pathologists focus on cause of death by examining a bod or corpse. They perform postmortem examinations. 

2. Insect activity will begin immediately if a body is left in the open. That is why insect activity can help investigations with determining certain things such as time of death, where the person died and the like. 

3. A light meal will digest in about 1-2 hours. Digestion rates can give useful information about when a person had died. Medium meals take about 3-4 hours to digest and heavier meals take about 6 hours. 

4. Indicative acts are actions or behaviors that may or may not have taken place before someone dies. Indicative is suggestive, so it may or may have happened. When you say indicative acts you are referring to what may have happened (or may not) based on certain circumstances, observations or evidence.
