Answer:
Mendel's law of independent assortment
Explanation:
Gregor Mendel is a really important figure in genetics, his work on pea plants provided us with many of the fundamentals of genetics that we still have today!
Mendel proposed 3 laws:
1. The law of dominance - this law states that where there are two different alleles (heterozygous) the organism will always express the dominant trait over the recessive trait
2. The law of segregation - this law states that offspring will inherit one allele from each parent, because allele pairs separate in the process of meiosis, such that each gamete contains 1 allele of each trait. When the zygote is formed, it contains an allele from each parent.
3. The law of independent assortment - this law states that traits are independent from one another at the time of gamete formation. The genes are segregated separately from one another, as the presence of one does not impact the presence of another.
This example shows that all combinations of the height and color allele are possible, and therefore nicely demonstrates the law of independent assortment
Answer: A Fixed Action Pattern
Explanation:
A fixed action pattern is an ethological term and off course a natural activity pattern that causes animals to act in a specific behavior pattern distinctive to their species. It is a pattern that is relatively unchangeable within the species and usually ends even when it is interrupted. You can say that, it is innate releasing mechanism or network where sign stimulus exists, once released from neural network; fixed action pattern leads to completion as well.
Answer: Sudden loss of habitat
Explanation:
Endangered species are animal or plant species that are in danger of going extinct.
This usually results from them suddenly losing their habitat and thus being exposed to unfamiliar conditions or threats that could end their existence. For instance, elephants losing their forest habitats in India and thus encroaching on farmland only to get shot for damaging farms.
Answer:
Phase of the cell cycle in which cells grow, duplicate organelles, and synthesize DNA.
S phase
Explanation:
DNA replication occurs in synthesis or in the S phase of the cell cycle. Each chromosome is copied with high fidelity in a process that involves a large number of enzymes. In this process the double strand of DNA breaks down and each individual strand is used as a template for the production of the complementary one. The result is the production of two identical copies of the genetic material.
