Epithelial tissue as she scrapes the top few layers of skin
Julli [10]3 years ago

Answer: Epithelial tissue.

Explanation:

<u>Epithelial tissue is one of the four basic types of tissues</u>, along with nervous tissue, muscle tissue and connective tissue.

Epithelial tissues form the covering of all surfaces, line body cavities and hollow organs. Therefore they are widespread throughout the body.

This type of tissue serves several important functions, such as:

  • Barrier: it prevents foreign materials from entering the body
  • Protection: it protects structures or tissues deeper in the body.
  • Sensation: Sensory nerve endings embedded in this tissue transmit sensations from the outside.

<u>An example of epithelial tissue is the epidermis, which is the outermost layer of the skin</u>. When Elaine fell off the bike, the most exposed tissue is the epithelium (skin) of her hands, and it's the tissue that was damaged.

If two organisms show a developmental homology you would also definently expect them to?
san4es73 [151]

If two organisms show a developmental homology you would also definitely expect them to share genetic homologies.

Homology is the similarity between two organisms. This similarity can be of body structures, physiology, etc. This homology is generally due to shared ancestral history between two organisms. For example, the wings of a bird and bats are homologous structures, this is because they have a common anatomy.

Genetic homology refers to the arrival from the same gene from a common ancestor. The same gene is shared between two organisms who may not be related in any other matter. Genetic homology can even be depicted by the sequences of a protein.

If the frequency of an allele is 0.75, how many copies of this allele should be in a population of 300 diploid individuals?
Ray Of Light [21]

I have provided the options below:

a. 150

b. 225

c. 300

d. 450

e. 75

Answer:

150

Explanation:

Hardy-Weinberg law states, the allelic frequencies of a gene that is, q and p follow the relationship p^2+q^2+2pq = 1, if the population is in equilibrium.

Therefore p^2+q^2+2pq = 1, can be used to calculate the percentage of the allelic frequencies i.e. p^2 and q^2

Allelic frequency = 0.75.

Therefore, the percentage of the allele in the population would be given by

0.75^2 = 0.5625 = 56%.

And the total number of individuals with this allele in the population:

number of individuals = 56×300÷100

= 168 or

150 nearest figure.
