A stalked, sessile marine organism has several feathery feeding structures surrounding an opening through which food enters. The

organism could potentially be a cnidarian, a lophophorate, a tube-dwelling worm, a crustacean, or an echinoderm. Which of the following traits, if found in this organism, would allow the greatest certainty of identification?
Select one:a. a nervous systemb. the presence of what seems to be radial symmetryc. a digestive system with mouth and anus separate from each otherd. a hard covering made partly of calcium carbonatee. a water vascular system

Answer:

        The right answer to this question is water vascular system.

Explanation:

        Through this system it's possible to identify it easily an echinoderm, that's why we can use it as a method of checking the information. But be careful, because for example, the radial symmetry, is not present in all the kinds of animals said on the question, shrimps are good examples, shrimps are part of the crustaceans. In this way, as you first see the organism, you are going to guess what it is by its appearance, and then you're going to analyse it properly after. Once you check it has a water vascular system, it's most probably to be an echinoderm.

What description best explains why viruses can become more pathogenic to host that were not affected by the virus before?
ANEK [815]

Answer:

New cells are naive to the infectious cells who attack it or they are not well prepared to deal with the different scenarios. But, the cells who are attacked before has the set or sequence of the viral or bacterial genome strand been identified by them, which leads to more safety or protection from these foreign bodies.

Explanation:

  • Mechanism To attack a host cell:

The viruses and other infectious material enters and attacks the host cell, by breaching its membrane wall and installing or leaving a gene of its own inside the cell. Which then combines with the genome of the cell and it goes through the process of replication, translation etc,along with the host cell machinery. Which then spreads the specific gene strand more in the environment

  • <u>Camouflage obtained by the infectious cell to hide it self:</u>

After the genome enters the host cell at first it does not recognizes the strands or foreign cells, as they cover there body with a camouflage sort of membrane and they look more like the body cells.

  • <u>Reactions by the host cell and as a whole the body:</u>

The organisms detects the genome of the infections cells or strand, as they store the data about it in its server or database. As if the next time they were under attack then precautions will be there by the host cell to deal with it.

As for the cell who are never attacked before will be less safe to deal with these foreign bodies.

What influences other than humans affect genetic drift in populations?
Lelu [443]

Answer:

Every population experiences genetic drift, but small populations feel its effects more strongly. Genetic drift does not take into account an allele's adaptive value to a population, and it may result in loss of a beneficial allele or fixation (rise to 100% frequency) of a harmful allele in a population.
