Answer:
The correct answer would be option D) no gametes.
Explanation:
The ABC model of the flower was formulated to describe the collection of genetic procedures that determines floral organs in several plants. These species consist of four whorls which are sepals, petals, stamens, and carpels. These whorls are expressed by the expression of a number of genes present in each whorl or verticli.
Gene A is solely responsible for the sepals while the co-expression of A and B genes are responsible for the petals. The identity of the stamens is expressed by B and C and the carpels require C and D genes to be active.
The homozygousity for a normal mutation in gene C will lead to inactive or lack stamens and carpels, which are male and female reproductive organs. These are an important structure for forming gametes.
Thus, the correct answer would be option D) no gametes.
Answer:
a. Let us consider that L is responsible for late and l is responsible for early. From the mentioned data, it can be concluded that allele L or late is dominant over early. By crossing plants 1 and 4 we get the expected ratio of 3: 1, which shows that it follows Mendel's law of dominant.
b. The genotype of all the four plants are:
1st plant = Ll
2nd plant = ll
3rd plant = LL
4th plant = Ll
c. If the plant 1 is self-fertilized then the expected progeny will be 3 (late): 1 (early).
In case if the 2nd plant is self-fertilized, the expected progeny will be only early.
In case if the 3rd plant is self-fertilized, the expected progeny will be only late.
In case if the 4th plant is self-fertilized, the expected progeny will be 3 (late): 1 (early).
Answer:
sharks are not cold blood killers because they don't kill for fun they kill because they are confused because when they see a human in the water swimming or splashing so they might try to investigate but sharks have more to fear to us than we do to them

The answer is B. both need food and air
Answer:
Explanation:
This is a stroke and the site of injury is the left side of the brain, this occur when the flow of oxygen-rich blood to a portion of the brain is blocked. Without oxygen, brain cells start to die after a few minutes.
A stroke occurs if their sudden bleeding in the left side of the brain, the right of the body will be affected, producing some of the following: numbness and weakness of the right arm and leg Speech problems (inability to form words). Amongst other symptoms.
The left side of the brain is responsible for controlling the right side of the body.
Stroke may occurs at any age and strock risk increase with age
