Pangea began to split around 200 million years ago, and the first primates ensued around 85 million years ago.
What is Pangea?When a three-pronged fracture developed between Africa, South America, and North America, Pangea first started to split apart. A volcanic rift zone was formed when magma welled up through the crustal weakness and rifting started.
As these split, continent-sized pieces of Pangea divided, volcanic explosions threw ash and volcanic debris throughout the terrain.
North America was being gradually pushed away from the rift zone and westward. A sequence of down-dropped fault blocks that closely parallel today's coastline were created as a result of the heavy continental crust that made up the new east coast collapsing.
Therefore, Pangea began to split around 200 million years ago, and the first primates ensued around 85 million years ago.

What are cytokinesis and mitosis?Mitosis is a cell division type that divides the parent cell and the genetic material into two alike daughter cells with the same chromosome numbers.
Cytokinesis is a process by which at the end of the telophase the cytoplasm of the cell starts dividing and results in the formation of the plate in plants and furrows in the animal, dividing the cell equally.

The correct answer is option D, that is, brainstem.
The innermost region of the brain is known as the brainstem, which continues with the spinal cord. It is the part of the brain, which associates the cerebrum with the spinal cord. It comprises the medulla oblongata, pons, and the midbrain. The sensory and the motor neurons pass via the brainstem permitting for the transmission of signals between the spinal cord and the brain.

What is the probability of the offspring having red-green color blindness for the cross that is represented by the Punnett square? 0 percent 25 percent 50 percent 75 percent.
Answer:
B. 25%
Explanation:
100% on unit test review
To determine the probability of the offspring having red-green color blindness from the Punnett square, we need to know the genotypes of the parents. The probability of having a female offspring with normal color vision (X^RX^R genotype) is 0%, and the probability of having a male offspring with normal color vision (X^RY genotype) is also 0%.
What is Red-green color blindness?
Red-green color blindness is a sex-linked recessive trait that is carried on the X chromosome. Females have two X chromosomes, while males have one X and one Y chromosome. A female who carries one normal X chromosome and one X chromosome with the color blindness allele is said to be a carrier.
A male who inherits the color blindness allele on his X chromosome will have the condition because he does not have a second X chromosome to compensate for the mutation.
Assuming that the mother is a carrier (X^RX^r) and the father is not color blind (X^RY), the Punnett square would look like this:
| X^R | X^r
--|------|-----
X^R| X^RX^R| X^RX^r
--|------|-----
X^Y| X^RY | X^rY
The possible genotypes of the offspring are X^RX^R, X^RX^r, X^RY, and X^rY.
X^RX^R: Female with normal color vision.
X^RX^r: Female carrier with normal color vision.
X^RY: Male with normal color vision.
X^rY: Male with red-green color blindness.
From the Punnett square, we can see that there is a 50% chance that the offspring will inherit the normal X chromosome from the mother and a 50% chance that they will inherit the normal X chromosome from the father.
Therefore, the probability of having a male offspring with red-green color blindness (X^rY genotype) is 50%, and the probability of having a female carrier offspring (X^RX^r genotype) is also 50%.

What are the genotypes of each blood type, and which blood type is an example of co-dominance?
Answer:
AA, AO, AB, BB, BO, and OO, with AB being co-dominance.
Explanation:
The AB blood type is co-dominant since both the A and B alleles are expressed. Please note that sometimes textbooks and teachers prefer the more correct use of I^A ect. I'll put a picture below to show you.
Another note: There are only four phenotypes but technically 6 genotypes, the reason being that AO is expressed as A and BO is expressed as B.

1. If you drive at 100 km/hr, S for 600 km,how long will it take you to go their?
2. A car traveled at a velocity of 50 km/h,N for .5 h. How far did the car travel?
Thank you I need it now 2/21/22
Science
Answer:
1: 6hr 2: 25km
Explanation:
The equation velocity=distance/time (v=d/t) is useful for these problems.
1: v=100 km/hr, d=600km
plugging into the equation, we get 100km/hr=600km/t
rearrange to get t=600/100, or t=6hr
2: v=50km/hr, t=5hr
plugging in: 50km/hr=d/0.5hr
rearrange: d=(50km/hr)*0.5hr, or d=25km
