Answer:
genotypes : BB, Bb, bb
heterozygote: Bb
homozygotes: BB (dominant), bb (recessive)
phenotype: B-black fur, b-white fur
Explanation:
- The term genotype refers to expression of two alleles in the same locus of two nonsister chromosome. Which denoted as BB,Bb, bb.
- The term heterozygote refers to expression of two different allele. That is Bb.
- The term homozygote refers to expression of two same allele. Which are either dominant( express in phenotype both in homozygote or heterozygote condition, that is B-black fur) or recessive(express in phenotype only in homozygote condition, that is b-white fur).
Domes resemble anticlines, but the beds dip uniformly in all directions away from the center of the structure. Domes are caused by compression and uplift. <span>Basins resemble synclines, but the beds dip uniformly in all directions toward the center of the structure. Basins are caused by compression and downwarping.</span>
Invasive species can either replace an organism from the ecosystem food web or replace it.
Explanation:
- Invasive species are non-native species which can be animals, plants, micro-organisms, fish, etc. they are very much threatening to the native species and ecosystem food web.
- Invasive species are spread by humans mostly, it happens unintentionally when people travel and all. Even climate change could be a reason for its spread.
- So, it becomes threatening to native species because when you introduce it into a new ecosystem, it does not have a predator or control. It grows aggressively and takes over the resources for the native species.
Salinity refers to an increase in the dissolved salt content of a body of water. Salinity has great impacts on the type of organisms that live inside the water. In the question given above, the salinity occurs as a result of non natural influence; since most of the organisms living inside the water before probably have specific optimal salinity range, if the salinity exceed the range they can cope with, they will probably migrate away from the water, those that refuse to migrate will probably die out and new species which can cope with the salinity level will emerge.
Answer:
Thymine and uracil or adenine have two hydrogen bonds between them, whereas guanine and cytosine have three.
