Is interest in renewable resources new to the United States? Explain your answer.

2 answers:

5 0

Renewable energy is growing fast in the U.S., but fossil fuels still dominate. Most Americans (77%) say it's more important for the United States to develop alternative energy sources, such as solar and wind power, than to produce more coal, oil and other fossil fuels, according to a recent Pew Research Center survey.

The ABO blood group assorts independently of the Rhesus (Rh) blood group and the MN blood group. Three alleles, IA , IB , and i,

Eva8 [605]

Answer:

Part 1:

The mother’s genotype is ii, rr, MN

The father’s genotype is IAIA/IAi, Rr, MM

Part 2:

Approximately 1/32 (3.125%) of children can be expected to have the stated blood types.

Explanation:

Part 1:

The mother has blood types 0, Rh- and MN. Therefore, her genotype has to be ii, rr, MN.

The father has ABO type A. His ABO genotype may therefore be either IAIA or IAi, as both are compatible with type A offspring with a type 0 mother. His Rh genotype must be rr, since his Rh- child necessarily has to have inherited one r allele from each parent. Finally, his MN genotype has to be MM since both alleles are codominant.

Part 2:

Using the given data, we build the following Punnett chart:

IA R N IA r N i R N i r N

IA R M

IA R N

IA r M

IA r N

IB R M

IB R N

IB r M X

IB r N

Note that, of all 32 possible combinations, only a single one of them (marked with “X” produces a genotype which matches the desired blood type, as follows:

genotype: IBi, rr, MN

blood type: B, Rh-, MN

From a chemical view, how is an amino acid is being recognized by its specific aminoacyl tRNA synthetase?

nydimaria [60]

Answer:

An aminoacyl-tRNA synthetase (aaRS or ARS), also called tRNA-ligase, is an enzyme that attaches the appropriate amino acid onto its corresponding tRNA. It does so by catalyzing the transesterification of a specific cognate amino acid or its precursor to one of all its compatible cognate tRNAs to form an aminoacyl-tRNA.

sodium, chloride, and potassium in cells and body fluids are examples of: question 54 options: phytates. electrolytes. condensat

Troyanec [42]

(b) electrolytes are what sodium, chloride, and potassium in cells and body fluids are examples of.

When dissolved in water or bodily fluids, a substance called an electrolyte separates into ions (particles having electrical charges). The ions sodium, potassium, calcium, chloride, and phosphate are only a few examples.

The many electrolytes include sodium, calcium, potassium, chloride, phosphate, and magnesium. They come from the meals you consume and the liquids you drink.

Your body's electrolyte levels might get too high or too low. When your body's water balance changes, this may occur. The amount of water you consume and lose should be equal. If something throws off this equilibrium, you can be dehydrated or have too much water on your body (overhydration).

Here is another question with an answer similar to this about electrolytes: brainly.com/question/28699046
