Answer: The full explanation below.

Explanation: The advantage of Relative dating is it can tell if a rock is older or younger that a certain object where the age is also not certain making it easier to tell when the other object was from, however it dose not give an exact age of the rock. Absolute dating is different because it gives you the exact age of the rock, but does not aid in find the age of any artifacts that can be found around it. Hope this helps! :D

The recombination frequency between linked genes A and B is 40%, between B and C is 20%, between C and D is 10%, between C and A
Alja [10]

Answer:

ACDB (or BDCA)

Explanation:

The linked genes A and B have a greater frequency of recombination (40%) and therefore they are found furthest away on the chromosome. Conversely, the smaller distance is between D and B, which exhibit a lower frequency of recombination (10%), while C is localized at the same physical distance of both A and B (20%), so the physical map is ACDB.

Physical map:

A--------C-----D-----B

If a bacteria is positive for the enzyme urease and is inoculated in a urea reduction broth tube at 37∘C for 24 hrs, what color
Vedmedyk [2.9K]

Answer:

The color would be Pink

Explanation:

According to the question, the bacteria is positive for the enzyme urease and it's inoculated for 24 hours.

Urease broth is a differential medium that tests the ability of an organism to produce urease, that hydrolyzes urea to ammonia and carbon dioxide. The broth contains two pH buffers, urea, a very small amount of nutrients for the bacteria, and the pH indicator phenol red. Phenol red turns yellow in an acidic environment and fuchsia in an alkaline environment.

If the urea in the broth is degraded and ammonia is produced, an alkaline environment is created, and the media turns pink within 24 hours.

Many enterics can hydrolyze urea; but only a few can degrade urea rapidly. These are called “rapid urease-positive” organisms.

Urea broth is formulated to test for rapid urease-positive organisms. The restrictive amount of nutrients coupled with the use of pH buffers prevent all but rapid urease-positive organisms from producing enough ammonia to turn the phenol red pink.

Somatic is to autonomic as ______ is to ______.
Colt1911 [192]
<span>Somatic is to autonomic as voluntary is to involuntary.
The autonomic nervous system or visceral nervous system (also called vegetative nervous system) is the part of the nervous system responsible for functions not subject to voluntary control (like heart rate, breath...).

The somatic nervous system is the part of the peripheral nervous system that controls the movements and position of the body and allows to perceive through the skin various sensations (touch, heat, pain) and discover through the other sense organs the surrounding environment (like vision, hearing, olfaction...).

Both of the nervous systems consists of sensory neurons and motor neurons.

About rest and excitation, they are controlled by the two parts of the autonomic nervous system (sympathetic an parasympathetic).</span>
