The right answer is 10 amu.

The unit of unified atomic mass, of symbol "u", is a standard unit of measure, used to express the mass of atoms and molecules.

This unit does not belong to the International System (SI), and its value is obtained experimentally. It is defined as 1/12 of the mass of a nuclide 12C (carbon 12), unbound at rest and in its ground state. In other words, a 12C atom has a mass of exactly 12u, and a mole of 12C atoms (N atoms, where N is the number of Avogadro) has a mass of exactly 12g. As a result, 1 u is approximately 1.660 538 921 × 10-27 kg.

The average mass of a nucleon depends on the total number of nucleons in the atomic nucleus, because of the mass defect. This is why the mass of a proton or a neutron taken separately is strictly greater than 1 u.

In the nucleus, we can see that there are 10 nucleons (protons and neutrons) so the mass of the atom is close to 10amu.

In clover plants, the pattern on the leaves is determined by a single gene with multiple alleles that are related in a dominance

igomit [66]

Answer:

The correct answer is -

a. 7

b. 7 (p1p1, p1p2, p1p3, p1p4, p1p5, etc

c. p7 is abundant

Explanation:

According the question the dominance of the big leaves is p7 > p6 >p5 >p4 >p3 >p2 >p1 where 1 represent least dominance and 7 represent most dominance

let represent the phenotype with the numbers 1 to 7 and genotype with a combination of these numbers so the genotype in respect of phenotype would be :

p7p7,p7p6, p7p5, p7p4, p7p3, p7p2, p7p1 - most dominant 7

p6p6, p6p5, p6p4, p6p3, p6p2, p6p1 - 6

p5p5, p5p4, p5p3, p5p2, p5p1 - 5

p4p4, p4p3, p4p2, p4p1 - 4

p3p3, p3p2, p3p1 - 3

p2p2, p2p1 - 2

p1p1- 1 least dominant

Thus, there are 28 different combinations or patterns of genotypes. 7 phenotypes patterns.

Arrange the three kinds of nitrogenous wastes based on the energy required to synthesize them, beginning with the waste product

Evgen [1.6K]

the three kinds of nitrogenous wastes based on the energy required to synthesize them are arranged; Ammonia < urea < uric acid.

Nitrogenous wastes are the nitrogen compounds that organisms use to get rid of excess nitrogen. Ammonia, urea, and uric acid are the most common nitrogenous wastes that animals excrete. Protein metabolism generates all of these nitrogenous wastes.

Ammonia is the most toxic of these nitrogenous wastes, and it is the most common but requires the least energy. Urea is more harmful than uric acid, but it is less harmful than ammonia, reducing the amount of energy required to synthesize it. Uric acid is the least harmful, a non-poisonous particle with four nitrogen molecules. This is useful for birds and reptiles that lay hard eggs because it eliminates the most nitrogen, uses the least amount of water, and is not toxic. It also takes the most energy input.
