Answer:
Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are perhaps the most important molecules in cell biology, responsible for the storage and reading of genetic information that underpins all life. They are both linear polymers, consisting of sugars, phosphates and bases, but there are some key differences which separate the two1. These distinctions enable the two molecules to work together and fulfil their essential roles. Here, we look at 5 key differences between DNA and RNA. Before we delve into the differences, we take a look at these two nucleic acids side-by-side.
Explanation:
The molecule will enter the cell using a channel protein.
Answer:
Genotype: Bb (heterozygous)
Phenotype: brown fur
Explanation:
Since allele B is dominant to allele b, as long as genotype has allele B in it, its effect of phenotype will be expressed instead, regardless of whether allele b is present.
As mouse genotype is stated as Bb, on the chromosome from its parents, allele B comes from one parent while allele b is inherited from the other parent.
Phenotype is the expressed trait. In this case, as genotype has allele B, the phenotype will be brown fur as its effect is expressed.
Answer: analysis the similarities and differences between organisms of the same species
Explanation:
Comparative morphology is analysis of the patterns of the locus of structures within the body plan of an organism, and forms the basis of taxonomical categorization. Functional morphology is the study of the relationship between the structure and function of morphological features.
Answer:
Selection that acts, over evolutionary time, to enhance traits that increase an individual's ability to mate frequently or with quality partners is known as <u>sexual selection.</u>
Explanation:
Sexual selection : The process through which males and females attempt to maximise their chances of reproductive success is called sexual selection. It is a form of natural selection. Charles Darwin suggested sexual selection. Animals compete with others of the same species for the chance to mate.
<u>For example:</u> Male widow-bird grows exceptional long tail feathers, females lack tail feathers.
