In the DESERT Biome , which of the following could be an example of commensalism?
A. A gopher snake occupies a burrow made by the desert rat.
B. A chipmunk takes shelter in an oak tree and is protected from predators and in return, disperses seeds around the area.
C. Wasps lay eggs in the case of eggs laid by the praying mantis. When the wasp eggs hatch, the larvae feeds on the eggs of the praying mantis.
D. A tapeworm gets into a moose and causes harm
E. A fox follows a caribou that removes the snow covering to get to the lichens under the soil. The fox then hunts the animals that have been uncovered.
<u>F. A desert coyote eats fruit and in return disperses the seeds of the fruit around through its scat (poop).

Answer:
A) stratum basale.
Explanation:
The epidermal layer consists of five layers. This is not having any blood vessels and known as avascular. The four-layer starting from stratum basale to stratum corneum is referred to as thin skin. But the skins of foot and palm has another layer called stratum lucidum. This layer forms the five layers of the epidermis.
The stratum basale is the deep layer of the epidermis. Below this layer dermis is present. This layer consists of basal cells which are precursors of keratinocyte cells. The stratum basale is a single layer cell and it undergoes continual mitosis. So that this cell produces new cells and these new cells replace the other older cells above it.
As the basal cells are precursors of keratinocytes, they produce all keratinocytes of the epidermis.
Two other types of cells are produced from this layer - Merkel cell, and melanocyte. Merkel cells act as touch receptors and melanocytes produce melanin pigments.
The sequence of nucleotides in the template strand of DNA could code for the polypeptide sequence Phe-Ser-Gln is AAG, AGG, and GUU.
<h3>What are Nucleotides?</h3>
Nucleotides may be defined as a molecule that consists of a nitrogen-containing base, a phosphate group, and a pentose sugar.
The codons that codes for the given amino acids are as follows:
- Phe = UUC
- Ser = UCC
- Gln = CAA.
Therefore, The sequence of nucleotides in the template strand of DNA could code for the polypeptide sequence Phe-Ser-Gln is AAG, AGG, and GUU.

Answer:RNA polymerase synthesizes an RNA transcript complementary to the DNA template strand in the 5' to 3' direction. It moves forward along the template strand in the 3' to 5' direction, opening the DNA double helix as it goes.
