A stands out most to me, CO comes from the air and air is basically oxygen we breath. When we exhale CO comes out (of course). I would say A is correct.
Darwin lived in a time where natural selection was a strange theory among scientists and researchers. This was especially true when other researcher Lamarck argued that organisms passed on helpful traits to their offspring, that they magically could form a new trait to adapt to their environment and then pass it onto their offspring. For example, if a giraffe was too short to reach food, it would grow a larger neck in its lifetime and then pass that trait onto its offspring. Darwin argued that, through the process of survival of the fittest, that short giraffe would die off and never receive the chance to pass on its shortness to future populations. Thus, taller giraffes would survive— they can reach food, shorter giraffes can’t— and the short genes would disappear. The fact that Darwin was introducing a new theory that nobody was used to at the time was peculiar, so he had few people on his side until long after his observations.
Another problem Darwin had was the lack of technology. To travel, Darwin would have to use boats to reach far away places, and of course, this took time.
The final problem Darwin had was the extra time it took for evolution, a process that can take up to millions of years. Evolution didn’t occur over night— it took time for Darwin to conduct experiments, observe, conduct them again, come to a conclusion, and so on.
Hope this helped a little!
The best answer to fill in the blank would be B) Small intestine or the second option.
Inhibin inhibits the secretion of FSH only.
<h3>What is the role of inhibin?</h3>
- Inhibin is a protein mainly produced by the gonads.
- In men it is produced by the Sertoli cells and it is produced by the granulose cells in women.
- It negatively regulates the secretion of Follicle Stimulating hormone (FSH) from the pituitary gland.
- FSH itself induces the production of inhibin for negative feedback.
- Pituitary is a pea shaped endocrine gland present at the base of the brain. It is the major endocrine gland and controls growth, development and functions of other endocrine glands.
- Hormone activin has opposite effect to inhibin. It enhances FSH biosynthesis and secretion.

#SPJ4
Explanation:
A. Shine-Dalgarno Sequence:
- This is a binding site found in the messenger RNA (mRNA) in prokaryotic organisms. It is found upstream of the start codon AUG and aids in the initiation of protein synthesis
B. SRP:
- Signal Recognition Protein (SRP). This acts by binding to the bacterial ribosome, which as a result restricts protein synthesis.
C. NLS:
- Nuclear Localisation Signal is a short amino acid sequence, which is responsible for transporting proteins from the cell cytoplasm into the nucleus. The NLS is also responsible for the development of the nuclear envelope of the cell.
D. Ubiquitin:
- Found predominately in Eukaryota, the ubiquitin is a protein that aids in the control of other proteins within the organism.
E. Specificity Factor:
- Also known as the sigma factor, is responsible for the initiation of bacterial transcription. It is recycled during the transcription process and is only required at the initiation of transcription.
F. CRP:
- cAMP Receptor Protein (CRP) is involved in catabolite (glucose) repression and serves as an inducer in the process.
