Answer:
Negative feedback results in the inhibition of an enzyme in a biochemical pathway, reducing the activity of earlier enzymes, and stopping the pathway. Positive feedback results in the activation of more enzymes, thus increasing its production of the product.

When would a point mutation occur?
O It can occur before and after cell division
O Before the cell divides
O After the cell divides
Before DNA replication
Answer:
Point mutations usually take place during DNA replication. DNA replication occurs when one double-stranded DNA molecule creates two single strands of DNA, each of which is a template for the creation of the complementary strand. A single point mutation can change the whole DNA sequence.
Explanation:
DNA replication occurs when one double-stranded DNA molecule creates two single strands of DNA, each of which is a template for the creation of the complementary strand. A single point mutation can change the whole DNA sequence.
Point mutation is the genetic maturation where the single nuclide base is changed s inserted or deleted from the DNS or the RNA.
The impacts can range from nor effects to dangerous effects with regards to protein production composition and function. The point mutation can take place during the DNA replication. Occurring when the double-stranded DNA created town strands.Hence the after the cells divide is correct option C

in the olfactory organs, the olfactory receptor cells are located within which type of epithelium
Answer:
In the apical layer of the pseudostratified ciliated columnar epithelium.
Explanation:
The sustentacular cells work as metabolic and material assistance for the olfactory epithelium. Analogous to neural glial cells, maintaining non-neural cells in the olfactory epithelium that are found in the apical zone of the pseudostratified ciliated columnar epithelium. The olfactory epithelium, located inside the nasal cavity, consists of olfactory receptor cells, which possess functional cilia expansions. The cilia trap odor molecules as they cross beyond the epithelial exterior. Data regarding the molecules are then forwarded from the receptors to the olfactory bulb in the brain. There exist two types of maintaining cells in the olfactory epithelium: sustentacular cells and microvillar cells.

Explain the relationship between urea cycle and citric acid cycle?
Answer:
one of its nitrogens through transamination of oxalacetate to form asparate and returns fumarate to that cycle.
Explanation:
The urea cycle is linked to the citric acid cycle by fumarate and by aspartate, which can be con- verted to malate by transamination (see Figure 23.22). ... Aspartate and arginosuccinate are the amino acids that link the two pathways. Aspartate is made by transamination of OxaloacetatA.
