Answer:

<u>Option-(C,A):</u>Archaea must undergo meiosis prior to cell division, and Each chromosome in a polyploid organism has distinct genetic information.

Explanation:

  • <u> Archaea are polyploid:</u>

Archea are prehistoric organisms who can be also termed as the prokaryotic living cells, as they developed from a less developed form to a more complex shape or system. As the feature of being a polyploid makes it easy for any archea to survive in the most severe conditions. As the polyploids contain a number of genetic materials in pair, as each pair is very distinctive in features or more independent in regulating a function then the other. Giving it a more diversity of genetic sequence its genome.

Along, with that the process of meiosis occurs prior to the process or event of cell division. Which is for production of the copies of the parent cell, which posses the same genetic material as that of the parent cells.

Which of the following is not a sign of possible pest infestation?
Brrunno [24]

The right answer is smelly garbage.

Infestation is the penetration into the body of a parasite whose nature is not microbial.

smelly garbage is not synonymous of infestation, because the olfactory system only detected smelly metabolites of these microorganisms. This does not necessarily mean that the microorganism has managed to penetrate the body.

By cons other proposals are signs and tools for infestation (torn packaging with food leaking out, dead insect bodysuits, feathers, and fur).

Which structure is at work when the body deals with reflex actions?
Ne4ueva [31]

Answer:

spinal cord

Explanation:

Reflex actions are the involuntary action of the body in response to a signal or stimulus. The reflex action of body is controlled by spinal cord.

Reflex arc acts as a neural pathways that transmit impulse to the brain via spinal cord. Sensory neurons pass through synapse in the spinal cord which activate spinal motor neuron to act immediately without any delay.

Immediate taking off hand from hot oven is an example of reflex action, which is regulated by spinal cord.  

Hence, the correct option is spinal cord.
