allsm [11]3 years ago
7 0

Answer:

option C = Pb

Explanation:

An atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.

All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other. For example if neutral atom has 6 protons than it must have 6 electrons. The sum of neutrons and protons is the mass number of an atom while the number of protons are number of electrons is the atomic number of an atom.

For example

The number of protons and number of electrons in lead are 82 and it shows its atomic number. while the number of protons plus neutrons are mass number which is 207.2 amu.

Ahat [919]

The answer is; codon, codon, anticodon

There are about 64 different combinations of three nucleotide bases into codons. The combinations, however, only code for 20 amino acids hence some codons are redundant. When the mRNA forms a scaffolding with the ribosome, the tRNA with the right anticodon (sequence complementary to the codon on the mRNA) to the codon on the A site of the ribosome,  leaves its amino acid at the site of chain elongation (P-site) and exits at the E-site.

What is the fitness advantage for the angiosperm approach to the formation of nutritive tissue?
kiruha [24]
<span>An advantage for the angiosperm approach to the formation of nutritive tissue is in energy conservation.</span> <span>The nutritive tissue is formed via double fertilization in Angiosperms. The advantage of double fertilization is that the plant does not invest energy in seed nutritive tissue until after an egg has been fertilized. This means that endosperm (nutritive tissue) starts to develop and store nutrients after it has been fertilized by a sperm cell.</span> Another advantage is that the endosperm nucleus is very active and <span>divides rapidly, so it forms the nutritive tissue very quickly.</span>

Yuliya22 [10]

Answer:

The parents must be Tt, Tt

Explanation:

Based on these results, we can conclude that each of the parents will have one dominant (T) and one recessive allele (t). We can prove this by drawing the Punnett square:

     T      t

T    TT   Tt

t     Tt     tt

We can see that the offspring will have the Tt genotype in two cases, the TT genotype in one case, and the tt genotype in one case, as well. Now we need to do some basic math. Two out of four is 50% (Tt - 50%), and one out of four is 25% (TT - 25%, tt - 25%).

This means that the parents must be Tt, Tt.
