The right answer is B and C.
For proposal C, I will give you an example, that of an autosomal recessive disease. If a parent is heterozygous for an allele causing an autosomal recessive disease (due to a mutation), it may be that it transmits the allele to its descendence, as it may not be able to transmit it (since in one heterozygous subject, not all of its gametes carry the mutated allele) and thus the mutation will no longer be copied through the generaitons.
Each individual is genetically unique. Its genes are distributed along chromosomes contained in the nucleus. Mutations can lead to the appearance of different versions of genes: alleles. A diploid individual has two copies of each gene, which may be identical or different alleles. Mixing during sexual reproduction partly explains the genetic diversity of individuals.
Answer: Carbon dioxide becomes a poisonous gas when there is too much of it in the air you breathe. Besides the effects it can have on the planet and the atmosphere, carbon dioxide poisoning can lead to central nervous system damage and respiratory deterioration in humans and other breathing creatures.
Explanation:
I dont see any answer choices, but my answer would be, Laws are descriptions; theories are explanations.
hope this was one, and hope this helped.
Answer:
The sample treated with RNase
Explanation:
According to this question, a novel virus was found which was capable of killing mice when injected into them and capable of making a nonvirulent virus to be virulent by transforming them.
After heat killing the novel virus, different samples were treated with either an RNase, a DNase, or a Proteinase. If the novel virus uses double-stranded RNA as its genetic material, the sample treated with RNase will no longer be capable of transforming the non-virulent strain. This is because RNase is a catalytic enzyme that degrades RNA, hence, the RNA will no longer be present to transform.
Surface tension<span> is the property of the surface of a liquid which allows it to resist an external force. It is due to the cohesive nature (stickiness and clumpability) of the water molecules. </span>Since water has a strong surface tension:
<span>1) </span>The surface tension of water provides the necessary wall tension for the formation of bubbles with water
<span>2) </span>It is responsible for the shape of liquid droplets, too
<span>3) </span>Small objects will "float" on the surface of a fluid, as long as the object cannot break through and separate the top layer of water molecules
If surface tension is weak, the reverse happens. Bubbles will come from round to spherical, small objects will not float, w<span>ater will fall as it is, without forming spherical droplets and will not immediately spread. </span>
