but can be dangerous to people with weakened immune systems if it gets

outside the mouth.

If you were designing a lander to work on mars, where on earth would you test it? Why?
emmasim [6.3K]
Hmm good question. Well I would have to test it for where there are no living life. I would have to build another NASA in the County because there is plenty of room there. Mars is made out of Dusty Crust that is about 30 miles thick. And let's say that the desert's Dusty Crust is about 5 miles - 15 miles thick. That will give about the same amount of surface that mars has. So we would know what to build for a perfect lander to work on Mars. This isn't much but it is something.

then their heterozygous  genotypes are --

father = iB, iO  and mother = iA, iO

punnett square will be,

        iB        iO

iA     iA iB     iA iO

iO     iB iO    iO iO

the genotypes of their progeny will be, iAiB ,  iAiO ,iBiO and iOiO

and phenotypes will be 3 are heterozygous and 1 is homozygous.

List and describe the functions of carbohydrates in the body. Explain how the body maintains glucose levels, including which hor
kicyunya [14]

Answer:

There are different function performed by carbohydrates in the body like-

Storage: When there is excess glucose present in the body they are stored as glycogen in muscles and liver.

Providing energy: Carbohydrates are the primary source of energy for the cells present in our body.

Carbohydrate helps to spare proteins and lipids and helps in providing polysaccharides for membrane carbohydrates.

The body maintains blood glucose levels through hormones. For example, when the blood glucose level gets high insulin is released in the blood by the pancreas which reduces the blood glucose level by accumulating glucose as glycogen in the liver and muscle.

Glucagon works opposite to insulin and increases the blood glucose level.
