Describe the location and cellular composition of the olfactory epithelium

Biology
1 answer:
Stolb23 [73]2 years ago
6 0
The olfactory epithelium occupies an area of about 5 cm2 in the roof of the nasal cavity. The specialized receptor cells in the olfactory epithelium are surrounded by supporting cells, non-sensory epithelial cells. The olfactory receptor cells are bipolar neurons whose olfactory cilia extend outward from the epithelium.

Why can’t nucleic acids be formed by sugars alone?
Fofino [41]

Answer:

Nucleic acids

Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are made up of nucleic acids found in the nuclei of living cells. They are the vehicles of genetic inheritance.

Nucleic acids are condensation polymers of nucleotides. To understand their functions you will find it helpful to look at how their molecules are built up and the structures of these molecules.

The following DNA is being replicated and the origin of replication is in the middle of the sequence and marked with three stars
xxTIMURxx [149]

Answer:

5'GATCGTAA3'

5'ATTCTAGA3'

Explanation:

As requested in the question above, the primers were presented with 8 nucleotides, with the nitrogenous bases of the DNA, and in the 5'-3 'direction.

Primers are small fragments of DNA that are used by DNA polymerase to form new strands. The primes attach to pieces on the ribbon, through the complementarity of the nitrogenous bases, serving as a template for the DNA polymerase to create the new ribbon.

DNA polymerase uses primers at the origin of replication, and can follow the path from the right or from the left, depending on the primers used, for this reason, this question has two answers.

Which of the following is a true statement?
FrozenT [24]

Answer:

a. Anabolic pathways build molecules, require energy, and are endergonic.

Explanation:

<em>Anabolic pathway </em>describes the metabolic reactions that<em> </em><em>build up</em><em> complex molecules from simpler ones</em>, typically via condensation (monomers covalently joined producing water as a by-product).<em> It </em><em>requires energy </em><em>to construct new bonds, this means is </em><em>endergonic</em><em>.</em>

The catabolic pathway, on the other hand, describes metabolic reactions that<em> </em><em>break complex molecules down </em><em>into simple ones</em>, typically via hydrolysis (consumption of water to break bonds within the polymer). <em>It </em><em>releases energy </em><em>when these bonds are broken, this means it is </em><em>exergonic</em><em>.</em>

Considering this information we can conclude that the correct answer is a. Anabolic pathways build molecules, require energy, and are endergonic.

I hope you find this information useful and interesting! Good luck!
