Answer:
The correct answer is: 25 %
Explanation:
According to Mandel's law of inheritance, the dominant allele masks the expression of the recessive allele if present together. If a couple has 3 children with brown eyes. In a monohybrid cross, the ideal phenotypic ratio of the offsprings is 3: 1 or in other words, the dominant character chances to appear is 75% in phenotype.
So, by the law of dominance of monohybrid cross the chances of the fourth child to develop blue eyes is 25%.
Thus, the correct answer is : 25 %.
The correct answer is option C. Single celled organisms and soft, bone less animals. The Precambrian ear was believed to be before evolution. Meaning more plants and complex animals. Therefore, organisms were single celled during that time.

Answer:
P⁵³ gene called as tumor suppressor gene is responsible for apoptosis.
Explanation:
The protein which encodes the gene belongs to a family of protein that have 3 members P⁵³,P⁶³ and P⁷³.
P⁵³ is known as tumor suppressor protein that is responsible for apoptosis of cells.
This protein is encoded by TP53 gene.This is important and play a crucial role in cell cycle an thus functions as tumor suppressor which involved in preventing cancer.Thus it is called called as "Guardian angel gene".
It not only function as anti cancer but also participate a crucial role in apoptosis,genomic stability and inhibition of angiogenesis.
It can also activate certain proteins that are which helps in DNA repair process.
Subduction zone
Explanation:
The feature created at the convergent of two oceanic crust having the same density is a subduction zone.
A subduction zone is covergent margin in which two plates pulls together and one goes under the other.
- Oceanic crusts are denser than the mantle below,
- When convergent occurs between them, one of the two plates will simply go into the mantle.
- This results in the formation of a subduction zone.
