Answer:
The main reasons are the following:
1. protect species still not described
2. discover new sources of biodiversity
Explanation:
Biodiversity can be defined as the variety of species in a given area/ecosystem. The loss of biodiversity due to the extinction of species or decline in the genetic diversity of the wild populations may potentially lead to a breakdown of the functioning of a given ecosystem. Therefore, the discovery of species still not described is fundamental in order to protect them and thus ensure the correct functioning of each ecosystem. Moreover, and since new species also represent new sources of biodiversity, they can potentially contain beneficial unknown compounds that can be used to develop new medicines for treating diseases and injuries.
Answer:
Mental illness is common. About 1 in 5 adults has a mental illness in any given year. Mental illness can begin at any age, from childhood through later adult years, but most cases begin earlier in life.
Explanation:
Answer:
Mr. Smith is not justified, Mrs. Smith can not be blamed necessarily for being unfaithful
Explanation:
Widow's peak is a dominant trait which means that it will be expressed both in homozygous and heterozygous condition. If "A" is the dominant allele and "a" is the recessive allele, the trait can be represented as AA or Aa.
Both Mr. Smith and Mrs. smith expressed the trait so they can either have AA or Aa genotype. If even one of them had AA genotype all the offspring would have the trait. But if both of them are heterozygous for it:
A a
A AA Aa
a Aa aa
There is 75 % probability of the child to have the trait (AA or Aa) but there is also 25% probability that the child does not express the trait (aa). Their second child belongs to this category and hence Mrs. Smith can not be blamed for being unfaithful.
