Answer:
The answer is 25%.
Explanation:
Hemophilia is a recessive illness that is x-linked.
If the husband has normal clotting ability, that means he has the dominant gene since he has only one X chromosome.
Since there is a probability that their child will have hemophilia, this means that the woman, who has 2 X chromosomes but has normal blood clotting abilities, has one dominant and one recessive hemophilia gene.
The probability that their first child will be a male is 50% and the probability that he will have hemophilia is also 50% since he will only get the Y chromosome from the father and the mother has one dominant and one recessive.
So the probability that their first child will be a son with hemophilia is 25%.
I hope this answer helps.
This statement giving a clue that there is asexually reproduction (may be binary fission) taking place and the progenies in asexual reproduction are genetically similar to parent cell. So answer is A.
<h2>Axons </h2>
Explanation:
Axons cross from one side of the spinal cord to the other through the gray commisure
- Each arm or extension of the gray matter in the spinal cord is referred to as a horn
- Projecting towards the back of the spinal cord are the dorsal horns (or posterior horns)
- Projecting towards the front are the ventral horns (or anterior horns)
- In the thoracic and upper lumbar regions of the cord, an additional pair of side projections occur, which are called the lateral horns
- A narrow band of gray matter known as the gray commissure stretches across of the center of the spinal cord and connects the two sets of horns
- In the middle of the gray commissure is the central canal, which contains cerebral spinal fluid
Answer:
D.
Explanation:
Seeds are the limiting factor.
Distillation is a process of separation of two liquids on the basis of their difference in the boiling points. There are two types of distillation process- Microscale distillation and miniscale distillation depending on the type of apparatus used for distillation.
In case of microscale distillation, microscale apparatus is used when the volume of liquid to be distilled is less than 5 ml. Whereas, in case of miniscale distillation, miniscale apparatus is used when the volume of liquid is more than 5 ml.
Hickman distilled head is used for microscale distillation whereas a bit larger vessels are used in miniscale distillation.
Micorscale and miniscale techniques have their own advantages. Both these techniques are cost effective, use less equipments and environmental friendly. Miniscale distillation is used yields more product which is easy to measure. Microscale distillation are difficult but it avoids large cumbersome distillation process and instruments.
