What is a point mutation and how does it affect the resulting protein?

1 answer:

8 0

Point mutations can have several effects on the behavior and reproduction of a protein depending on where the mutation occurs in the amino acid sequence of the protein. If the mutation occurs in the region of the gene that is responsible for coding for the protein, the amino acid may be altered.

Members of the phyla Cnidaria and Bryozoa both have a circle of tentacles, which they use for feeding. Besides the difference in

Sophie [7]

Answer:

C. Cnidarian tentacles have stinging cells, but Bryozoan tentacles are covered with cilia.

Explanation:

Cnidaria and Bryozoan, both teh phylum are classified under kingdom Animalia that contain aquatic animals found both in freshwater and marine environments.

They both use tentacles for feeding but there is diffference between there tentacles and feeding process.

Cnidarians tentacles are conist of stinging cells in the tips, which are called cnidocytes and a coiled thread-like stinger, called nematocyst. These stinging cells and nematocyst helps to capture and subdue prey. They feed over plankton or animals larger then them.

Bryozoan tentacles are covered with cilia and form an "O" or "U" shaped fold called lophophore, which helps to feed by sweeping the surrounding water. They generally feed on plankton, nudibranchs (sea slugs) and sea spiders.

Hence, the correct option is C.

Butoxors [25]

Answer:

The correct answer would be - predective ecology for ecological model evaluation.

Explanation:

Predective ecology involves the knowledge and data to predict the environmental issues and patterns in future. This method involves the knolwedge of ecology, physiology and physics to ccurately predict the changes will be seen in cosystem or ecology and its biotic and abiotic factor.

Model evaluation is also a method that alow ability to use the known data and model developed on this basis to predicts problems and patterns.

Consider the clinical scenario: Semen is very low in volume and the sperm cells have difficulty with motility because there isn'

zlopas [31]

Answer:

Seminal vesicle

Explanation:

Seminal vesicle secretes an alkaline and viscous fluid that constitutes about 60% of the volume of semen. The fluid secreted by seminal vesicle contains fructose which is a monosaccharide sugar, prostaglandins, and clotting proteins. The alkaline nature of the seminal fluid neutralizes the acidic environment of the male urethra and the female reproductive tract. This is required as the acidic conditions inactivate and kill sperm.

The fructose sugar serves a fuel for ATP production by sperm. Prostaglandins are responsible for sperm motility and viability as they stimulate smooth muscle contractions within the female reproductive tract. Therefore, a malfunctioning seminal vesicle would result in low semen volume and reduced motility due to the scarcity of energy.
