jeka57 [31]

Answer:

The correct answer will be option-A.

Inverted repeats are the sequence of the nucleotide in a nucleic acid which is identical but arranged in the opposite orientation. The inverted repeat may be separated by some sequence or they may lie adjacent to each other. They can be read the same from the backwards or forward direction.

In the given question since four bases when read from the forward direction is same as reading the sequence from the backward direction like CGAC can be read the same both backward and forward.

If an area is in the 50+ dBZ range, what atmospheric pressure conditions could the area be experiencing?
monitta

The atmospheric pressure conditions for a 50+ dBZ range differs from small to heavy hails.

Explanation:

dBZ refers to decibel relative to Z used in weather radar most of the times, in order to compare the reflection factor (Z) of a weather radar signal reflected off a remote object  to the return of a droplet of rain with a diameter of 1 mm.

dBZ is a logarithmic dimensionless technical unit, at 55 dBZ and above, most storms have hail which can throw off the rainfall rate because hail has a higher reflection.

Generally above 50 dBZ range the intensity varies accordingly for every 5 points. Such as small hail to moderate hail and from moderate to heavy hail.

Therefore the atmospheric pressure conditions differs from rains to hails.

When a tick transfers Lyme disease from a deer to a human, the tick is considered the ________ in the chain of infection
melisa1 [442]

The tick is considered the vector in the chain of infection.

Generally, vector organisms are organisms that are capable of transmitting disease pathogens from infected organisms to uninfected ones either directly or indirectly as a result of their activities.

Ticks are parasites that feed on the blood of vertebrate animals such as deers and humans. When they feed on the blood of animals with certain infections, the pathogens for such infections are sometimes carried in the guts of the parasites and these are transferred to the bloodstream of the next animal that would be their host.

A good example of this is Lyme disease.
