The correct answer is a substitution mutation.  

A mutation, which substitute’s one base for another, that is, a change in a solitary chemical letter like switching an A to a G is known as a substitution mutation. This kind of substitution can modify a codon to something, which encrypts a distinct amino acid and leads to a small modification in the generated protein.

kotykmax [81]

Answer:

basale - spinosum - granulosum - lucidum - corneum.  

Explanation:

The order of strata in the epidermis:

  • Basale: it is the deepest stratum. It has one layer of cells called keratinocytes, which are stem cells for the epidermis.
  • Spinosum: The keratinocytes in this layer have spiny shapes. They synthesize cytokeratin and lipids. In this layer, we can also find macrophages.
  • Granulosum: The keratinocytes of the previous layer ascend and synthesize keratohyalin, which is in granules. The keratohyalin helps to join keratin filaments. Also, the cells release the lipids synthesized in the previous layer, and they form a barrier that stops dehydration.
  • Lucidum: it is only on thick skin, like the one in the sole of the feet. The keratinocytes in this layer have expelled the nucleus and now are dead cells. The keratinocytes have a flat shape and form a thin layer.
  • Corneum: it is the most superficial layer. It is made of dead keratinocytes filled with keratin in their cytoplasm. It is a thick layer that suffers desquamation when new dead cells filled with keratin ascend from the previous layer.

6. species Closely related of orchids never mate in the wild because they bloom at different times. This is an example of ______
Dimas [21]

Answer:

temporal reproductive isolation

Explanation:

The correct answer would be temporal reproductive isolation.

<u>Reproductive isolation</u> generally refers to series of biological mechanisms or processes that prevent members of different species from mating/fertilization or prevent the product of their mating to be invalid.

Some reproductive isolation processes prevent members of different species from mating or prevent fertilization as a result of mating. These processes are known as pre-zygotic reproductive isolation mechanisms.

Some other processes ensure that the product of fertilization (when it occurs) is invalid. These are known as post-zygotic isolation mechanisms.

<em>A good example of the pre-zygotic reproductive isolation process is </em><em>when closely related by different species bloom at different times</em><em>. This will prevent mating or cross-pollination to happen between the different species. This is known as temporal reproductive isolation.</em>
