<h2>
The correct answer is explained below:</h2>
Explanation:
- According to the given question,
- For eye color, let the black color be represented by B allele and orange color be represented by b allele. Black is dominant over orange.
- For skin color, let the green skin be represented by G allele and white skin be represented by g allele. Green is dominant over white.
- The phenotype of Sam is black eyes and green skin so his genotype can be BBGG or BbGg. It is also said that one of his parents has phenotype orange eyes and white skin. That parent's genotype must be bbgg.
- Hence, the genotype of Sam must be BbGg.
- Carole has the phenotype of orange eyes and white skin. Her genotype would bbgg.
- The gametes produced by Sam are: BG, Bg, bG, bg.
- The gametes produced by Carole are: bg.
- Mating them we get,
BG Bg bG bg
bg BbGg Bbgg bbGg bbgg
(Black/ Green) (Black/ White) (Orange/Green) (Orange/ White)
- The genotypes and phenotypes (Eye color/ Skin color) obtained are represented above.
- The phenotypes (Eye color/ Skin color) obtained are in the following ratio:
(Black/ Green) : (Black/ White) : (Orange/Green) : (Orange/ White) = 1 : 1 : 1 : 1
Well your body is made up of mostly water and can damage your body because of dehydration
What on earth, please repeat the question clearer
Survivorship curve = so, first of all, it's a curve, as in a graph.
It describes "survivorship" - the rate of survival, in other words: out of 100 organisms that are born, how many survive. This rate is different among species, for example, most humans live out to most of their life span, and almost all can survive well beyond a reproductive age.
However, in frogs for example, many many individuals are born, but only few can survive to adulthood: most die very young, before reproductive age.
So if you hear about a new species: let's say dogs, and you want to know how long they would live, you would look at their sirvivorship curve (and in some breeds of dogs, those that are likely not to be in shelters, but in homes, the survivorship curve would be similar as in humans: almost all individuals born can live long.
Answer:
Soil erosion causes siltation in rivers, dams, etc. In some areas, huge river deltas are formed (such as River Nile delta) because of soil erosion. Such places are good for agriculture but not good for urbanization. However, some people do not care about it, they just want to construct buildings on alluvium type soils.
