Cause mammals are the only species that are well developed before birth unlike marsupial and monotremes
Cytokinesis is the point at which a cell with duplicated genetic material becomes two daughter cells with identical DNA.
Answer:
answer from google: ( see explanation )
Explanation: During the first stage of meiosis, the HOMOLOGUES (1-23) are segregated into different cells, resulting in 2 cells that each have 1 copy of each of the 23 chromosomes (still duplicated from DNA replication).
Answer: how a virus differs from a cell...
It doesn’t contain any kind of cytoplasm, cell wall, cell membrane, ribosome or mitochondrion.
It doesn’t have any sort of metabolic enzyme of its own. So, no nutrition system is seen.
It can’t reproduce itself, without any help of the host living cell.
It can be crystallized, centrifuged or diffused.
It doesn’t have any sort of somatic development.
Chemically, its just a fusion of protein and nucleic acid. So, this characters differ a Virus from a living cell.
Explanation:
The mechanism in which organisms best suited for their environment survive
and reproduce <u>NATURAL SELECTION.</u>
<u></u>
Explanation:
When individuals in a population compete for resources or live in their environment, the individuals with the slightest advantage over the others have an increased chance of reaching maturity and reproducing to passing down their genes to the next generations.
Natural selection works on the variations of the population to ‘select’ the best alleles of genes in the population that offer an advantage in ‘survival for the fittest’. This how natural selection fits a population to its environment. The greater the variation within a population, the higher its capacity to adapt to changes in the environment.
