Your "Digestive System" breaks down food into molecules that are then absorbed into your body.
Answer:
Lack of diversity = higher chance of extinction
high levels of diversity = higher chance of survival
Explanation:
The probable reasons behind the extinction of some Caminalcules are:
The ratio of males and females were not equal so that there were natural fight between male Caminalcules to get a female. This was one of the cause for lowering the population leading to extinction.
The excessive short-life of these Caminalcules was one of the main reason for their extinction as it is more difficult to real organisms because there would be an inherent bias against observing these species in fossil aseemblegs.
5. The two vestigial structures of Caminalcules were ear muscles and tail bones.
Answer:
A
Explanation:
the point of difference in isotopes is the number of neutrons. since they have the same number of neutrons, they are the same isotope.
Changing environments and competition for survival are the answer so D is the correct answer
Answer:
recombination and independent segregation of chromosomes during meiosis
Explanation:
Recombination and independent segregation of chromosomes represent the two most important meiotic mechanisms by which sisters from the same parents can inherit different gene variants and therefore look very different from each other:
1- Independent assortment (segregation) of chromosomes: during meiosis, homologous chromosomes are randomly distributed in daughter cells (which will give rise to the gametes), and therefore separate independently of each other. It is for that reason that gametes have unique combinations of chromosomes, which increases genetic variation.
2- Recombination, also known as crossing over, refers to the exchange of chromosome segments between non-sister chromatids during meiosis. This mechanism is well-known to produce new gene variants (alleles) in the daughter cells. In consequence, recombination also increases the genetic variation of the resulting gametes that will produce offspring (in this case, different sisters).
