Answer:
The answer to your question is below
Explanation:
Mitosis is a kind of sexual reproduction where a mother cell gives rise to two identical cells in which the initial number of chromosomes maintains the same.
So in this question, the products will be 2 daughter cells in which each cell will have 12 chromosomes.
Hormones can be divided into three classes. lipid-derived, amino acid-derived, and peptide (peptide and proteins) hormones. Cholesterol is a fat and fats are lipids. They fall into the protein and lipid category.
The collision theory<span> is based on the assumption that for a reaction to occur it is necessary for the reacting species atoms or molecules to come together or </span>collide<span> with one another.\</span>
Answer/Explanation:
Types of reproductive isolation include: temporal, ecological, mechanical, and behavioural.
A snail with a flat disc-like shell will not be able to mate with a snail having a conical shell - this is an example of mechanical isolation, where the animals are physically unable to mate due to incompatible body shapes and sizes.
The reproductive organs of male bush babies do not match with the reproductive organs of females of other bush baby species. - this is another example of mechanical isolation, as the sexual organs will physically not allow reproduction between these species
The mating call of a cricket is not recognized by a cricket of other species - this is an example of behavioural isolation, which results from incompatible mating rituals. I.e. the animals do not respond to each others mating behaviours
The signals sent by a male firefly are not recognized by the female firefly of other species. - this is also an example of behavioural isolation.
Temporal isolation is where species cannot interact because they do not have the same mating seasons or are not active at the same type of day. ?Ecological isolation occurs when two species do not come into physical contact to one another because they access different areas of the habitat. E.g. mating zones, food sources or nesting sites.
The answer is; E
This shows that these organelles were once free-living organisms with their own mechanisms for reproduction which they have retained even after years of symbiotic relationship with the higher organisms. During their duplication, they also replicate their own DNA. Their DNA does not have histones (as opposed to the DNA in the nucleus of their host eukaryotic cell) similar to that of simple organisms such as bacteria.
