<span>The kidney is made up of filtering units called nephrons. The number and size of nephrons slowly decreases with age, the kidneys start to lose its function, meaning, the waste and extra fluid are not filtered out of the body as effectively in older people. The kidneys become smaller with age, Blood flow to the kidneys is also reduced. This also impairs the filtering process.
Another function of the kidneys is to balance the amount of salt and acid in the body. This function also decreases with age, the production and efficiency of hormones that tell the body it is becoming dehydrated declines with age. This poses a risk for dehydration.
Bladder tissue becomes much less stretchable as one gets older. This decreases the amount of urine the bladder can hold. The muscles of the bladder also become weaker, making the bladder unable to squeeze hard enough to get rid of all the urine it contains, so more urine is left in the bladder after a person urinates. These two changes may cause an older person to have to urinate more often.
The sensation of needing to urinate is often delayed in older people. When an older person finally feels the need to urinate, the need may be sudden.</span>
Answer:
Explanation:
Geneticists use letters to represent alleles of different characters.
(Alleles: one of the two or more alleles of a character.)
A single letter is used to represent both the alleles of a particular character.
A capital letter represents a dominant allele, while a small letter represents a recessive one.
<u>The letters do not just have one standard representation</u>. same letter can be used to represent different characters. However, the letters may relate to the allele. For example: the letter 'B' can be used to represent Brown eyes.
Filtration
<span>Urea is the cellular waste product that the kidneys remove from the blood.Kidneys are the two bean shaped organs that has several functions to keep the body healthy. It not only removes urea from the blood, but also helps in the formation of urine and maintaining the fluid level of the body. The two kidneys are placed on the two sides of the spinal cord. The blood enters the kidney through the renal artery. The nephron within the kidneys mainly take out the waste products and the excess water from the blood and purifies it.If the kidneys of a person fail to work properly then it becomes important to perform dialysis for taking out the waste materials from the blood.</span>

4) Heterozygous I think
5) I think type B
and 6 not sure
Explanation:
i tried helping as much as i can since ik the stress i hope this helps and my answers MIGHT be wrong but this is what i think it is and what i remember. But what i can infer is that the child will get blood type B since the I is dominant
