4 0

Answer:

C)radial symmetry.

Explanation:

The central nervous system (CNS) is a part of the nervous system, it comprises the spinal cord and the brain. The brain plays in an important role in controlling most functions in the body such as movement, memory, speech etc.

Animals that have bilateral symmetry have a central nervous system because of the presence of the brain. But animals with radial symmetry such Cnidarians which include corals and jelly fish, do not have a central nervous system. Instead of the presence of neurons, they possess nerve nets.

Explain how the interaction of the Sun, the atmosphere, and the oceans produce winds.
Sergio [31]

Explanation:

The sun heats the air leading to warm air. the warm air rises thus makes the cooler air from the surroundings to replace it. This leads to creating wind . This same process applies for ocean currents.

The sun heats water which make warm water come to the surface of the ocean thus replacing it with cooler water leading to ocean currents.

Gene mapping for beak color and feather length in biology what is this
just olya [345]
I am not entirely sure about this. So maybe my response can help you find the answer a little better if my answer is not entirely right?

These last three questions are referring to everything you just worked on. So all you would have to do is refer back to your previous answers. Recall that the titles of the "part 1, 2, and 3" are titled "crossing beak color and tail-feather length", "crossing beak color and feather color", and "mapping tail-feather length and feather color".

1.List the distances between each pair of genes:
beak color and tail-feather length: 20 MU
beak color and feather color: 16 MU
tail-feather length and feather color: 4 MU

2.Which two alleles are the farthest apart?
(the one that is 20 MU apart) Y and L

3.Which two alleles are the closest together?
(the ones that are 4 MU apart) L and B

To find the graphical solution when adding vectors, you can draw a(n) ____ from the starting point to the ending point.
ehidna [41]

Answer:

arrow (which creates the resultant vector)

Explanation:

When you use the graphing technique when adding vectors, you can use the head to tail method to draw the vectors. And from the starting point or the tail of the first vector you drew, you will draw an arrow touching heads with the head of the last vector drawn.

With that, you can use a ruler to measure the resultant vector's magnitude, and use a protractor to measure it's direction.

Below is an example:

Let:

V1 = Vector 1

V2 = Vector 2

R - resultant vector.
