<h3><u>Answer;</u></h3>
The above statement is <u>False </u>
<h3><u>Explanation;</u></h3>
- Speciation is an evolutionary process in which new species arise. There are three types of speciation, namely; sympatric, parapatric and allopatric speciation.
- <em><u>Sympatric speciation is a pattern in which speciation occurs in the absence of a physical barrier to gene flow; ex. polyploidy arising in flowers.</u></em>
- In an Allopatric speciation on the other hand, a physical barrier arises and separates two populations, ending gene flow between them and allowing reproductive isolating mechanisms to evolve so that later if the two groups come back into contact they will no longer be able to reproduce together, therefore making them different species.
B that our early ancestors were tailed primates
Answer:
The rapid decolorization with ethanol or acetone
and counterstaining with safranin
When a decolorizer such as alcohol or acetone is added, it interacts with the lipids of the cell membrane. A gram-negative cell loses its outer lipopolysaccharide membrane, and the inner peptidoglycan layer is left exposed: when safranin is added they will turn red. Conversely, gram-positives retain the Cristal violet and will color in purple
Answer:
Heredity is the study of how traits are passed from parents to offsprings through reproduction. Off springs cells acquire the genetic information from their parents. DNA bases (A,G,C,T) determine the nucleotides that will constitute the mRNA, the mRNA nucleotides determines the codons which codes for certain amino acids. The amino acids join during translation and form peptides that then join to form proteins. These proteins include enzymes that catalyses chemical reactions for example pigments of skin and hair color are produced by enzymes. Hence, proteins highly determine the traits acquired by a given organisms and therefore, variation in a gene in terms of the bases greatly affect the proteins formed hence influencing the traits of the organisms.

Hope this helped Mark BRAINLIEST!!!!
Same genus is more closely related. The farther down the list Phylum-Class-Order-Family-Genus-Species you go, the more closely related are the species in that taxon.
