Answer:
CRISPR/Cas9 in its original form is a homing device (the CRISPR part) that guides molecular scissors (the Cas9 enzyme) to a target section of DNA. Together, they work as a genetic-engineering cruise missile that disables or repairs a gene, or inserts something new where the Cas9 scissors has made some cuts.

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.

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

What causes soils and their horizons to differ? a. Differences in climates where the soils are formed b. Differences in plant and animal life in different locations c. Differences in the layout of the land d. All of the above Please select the best answer from the choices provided A B C D.
The causes for the soil and their horizons to differ are differences in climatic conditions where soils are formed, differences in organisms in different locations, and differences in the distribution of the land. So, option D is correct, i.e. all of the above.
What is soil horizon?A soil horizon is a layer-by-layer parallel distribution of soil surface, whose physical, chemical as well as biological characteristics are varied from layer to layer.
The native habitat of every plant and animal life differs from place to place, the distribution of the land varies throughout the world, and there are different climates where soils are formed. So, the characteristics of soil depend on climatic conditions, organisms living in a particular area, and geographical locations.
Therefore, option D, i.e. All of the above is the correct option.

what does photosyntihies occur in
Answer:
Chloroplasts
Explanation:
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities. Some of this chemical energy is stored in carbohydrate molecules, such as sugars and starches, which are synthesized from carbon dioxide and water.
A chloroplast is a type of membrane-bound organelle known as a plastid that conducts photosynthesis mostly in plant and algal cells.

Answer:
(Option A) Nuclear membranes begin to form around the cell’s genetic material.
Explanation:
In the given image, it can be predicted that the nuclear envelop reappears around the cell's genetic material. The correct option is A.
What is mitosis?Mitosis is the process whereby a cell replicates and then separates its chromosomes, creates two identical nuclei in prep work for cell division.
Mitosis is commonly accompanied by the equal division of the cell's contents into two daughter cells with identical genomes.
Mitosis occurs in the following stages:
The chromosomes shorten and thicken during prophase. Metaphase - Chromosomes align in the center of the cell. Chromatids separate at the centromere and move to opposite poles during anaphase. Telophase - The formation of two nuclei after nuclear envelopes reform around each chromosome group.The image is showing telophase of the cell division mitosis, which is indicating that the nuclear envelop is being formed around the genetic material of the cell.
Thus, the correct option is A.

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%.
