The correct answer is option A
To develop a new variety of tomato there must be some change in the genes of the tomato.
The change in the genes of the tomato can happen by the process of mutation and this happens gradually over many years.
It takes several generations to evolve into a new variety of tomato. The genetic variation in the tomato is the result of mutation that will tend to give rise to a new variety of tomato.
Cholesterol is a steroid that is synthesized in the liver and serves several important functions in the body. It is the precursor to many hormones, such as testosterone and estradiol, and is also involved in the synthesis of vitamins and bile salts.

Cholesterol is a key component of the plasma membrane in animal cells and is important for maintaining cell structure, transport of materials, and cell communication. Overall, cholesterol plays a vital role in the proper functioning of the body.

Answer:
They have 1:4 chances of 0, 1:4 cahnces of AB, 1:4 chances of A, 1:4 chances of B
Explanation:
Blood has three types of alleles: A, B, 0 depending on the type of proteins in blood cells. They can have protein A, B, or not having them 0. The dominant allele will be B or A.
All types of blood are A, B, AB (co-dominance) and 0.
We all have two alleles for each gene, one comes from our mother, and one comes from our father.
If both parents are dominant, but they have a recessive child, you have both heterozygote genes to do the Punnett square.
Mother: I(A)i(0)
Father: I(B)i(0)
b. are typified by tweezers or forceps
c. have load at one end of the lever, fulcrum at the other, and effort applied somewhere in the middle
d. in the body can operate at a mechanical advantage or mechanical disadvantage, depending on specific location
Answer: d. in the body can operate at a mechanical advantage or mechanical disadvantage, depending on specific location.
Explanation:
A first-class lever is defined as the force in which fulcrum is present in the center and the load and effort on each side of the fulcrum. First class lever moves over a large distance to move the load to a smaller distance.
First-class lever can be operated at mechanical advantage or disadvantage that it can aid in work by changing the direction of the force and by increasing the efficiency. As the the fulcrum is between the load and the effort so the length of the effort arm divided by the length of the effort arm.
If the fulcrum is closer to the effort, it will operated at mechanical disadvantage and vice versa.
Example of first class levers includes scissors, a claw hammer, a see-saw and a weighing balance.
Hence, the correct option is D.
