Answer: Only Options A, C and E are correct
A) Sympatric speciation is best described as a random event that disrupts the allele frequencies in a population
C) Sympatric speciation does not require geographic isolation.
E) Sympatric speciation can be due to sexual(mate) selection
Explanation:
Sympatric speciation is a random or naturally occurring event whereby organisms of the same species:
> live in the same territory or nearby territories ( i.e not living in isolation)
> DO NOT interbreed, but select a sexual mate from a much diverse territory which results in an uneven gene flow or disruption of alleles among the population of same species of the parents organisms.
Answer option:
1. duplicate themselves
2. convert energy
3. selectively exchange materials
4. all of the above
Answer:
4. all of the above
Explanation:
Cells carry out many functions. They are able to replicate their DNA and divide into two identical daughter cells in order to proliferate.
They can convert glucose into cellular energy (ATP) through respiration in the mitochondria
They can exchange materials with the outside environment via the selectively permeable cell membrane, endocytosis and exocytosis and active transport via membrane proteins.
Therefore, all of the above is correct.
To protect them from ultraviolet rays from the sun.
