C. Sedimentary Layers, sedimentary rocks are created as a result of high pressure :)
I hope this helped!
<h3>Question from alternative source</h3>
Many different types of mutations can occur within the body. Cystic fibrosis is a genetic disorder that is caused by different mutations within the CFTR gene. One mutation in the CFTR gene that leads to cystic fibrosis causes translation to end earlier in the gene sequence. Which type of mutation causes this translation error that leads to cystic fibrosis?
- silent
- missense
- nonsense
- deletion
Answer:
Nonsense
Explanation:
Nonsense mutations describe mutations that produce a premature stop codon. The stop codons are UAG, UAA, and UGA. A way in which this could arise is, for example, if there was a substution of a nucleotide in the mRNA codon UAC (which codes for the amino acid Tyrosine) to the nucleotide UAG (which codes for a stop codon).
The translation machinery would reach this codon, which signals that translation should be terminated. This would mean that the mRNA would be released, and a truncated (shortened) version of the amino acid would be produced. This is likely to be non-functional, and may even be marked for destruction by the cell.
Answer:
false
Explanation:
The parathyroid gland refers to the four small endocrine glands located in the neck region behind the thyroid. It secretes the parathyroid hormone or parathormone which regulates the calcium levels in our bodies. It comprises two types of cells which are:
a. The oxyphil cells appear at the onset of puberty and they have no known functions. They appear pink or orange when stained with hematoxylin and eosin stain.
b. The chief cells are more abundant compared to the oxyphil cells and stain dark purple by the action of hematoxylin and eosin stain. Their major function is to produce parathyroid hormone which regulates the amount of calcium in the body.
No diagram shown, but it would be the fish/any other organisms near or in the shallow part/any part of a pond/lake.
Working in a lab means working under controlled environment. If in the generation 1 and generation 3, the number of bird’s increases or decreases in number, the possible conditions for this would
- The amount of food increased or decreased
- If a flock’s beak type made it easier to pick up the available food, the flock grows and vice versa
Justification: if the beak type for generation 1 makes the food intake easier, it will grow which ultimately decreases the food for the generation 3 which has un-supportive beak type.
