Carbon tends to form four bonds. what kind of bonds are they?

1 answer:

5 0

Carbon forms covalent bonds; the most usual kind of bond formed by carbon is a covalent bond. In the majority of situations, carbon shares electrons with other atoms because of the presence of four valence electrons.

As carbon has four valence electrons in its outermost shell, and as each covalent bond needs a donation of one electron to form the bond, carbon tends to make exactly the four bonds and is only stable if all four of these bonds are utilized.

In chickens, comb shape is determined by two independent genes (R and P). A walnut comb is produced when at least one dominant a

Aleksandr [31]

Answer:

Option B, Rr pp × rr Pp

Explanation:

Given

Walnut Comb is produces when one dominant allele R is present at one gene locus and at least one dominant allele P is present at a second gene locus - R* P*

Rose Comb - at least one dominant allele is present at the first locus and two recessive alleles are present at the second locus - R* pp

Pea comb - two recessive alleles are present at the first locus and at least one dominant allele is present at the second - rr P*

Single comb - two recessive alleles are present at the first and the second locus - rrpp

Parent are rose combed and pea combed

For being rose genotype must be R* pp

and for being pea combed genotype must be rr P*

Rr pp x rr Pp

will produce

Walnut comb with genotype Rr Pp

Single comb with genotype rrpp

and pea comb with genotype rrPp

Hence, option B is correct

Why is it imprtant for the ova and sperm cell to each contain a haploid number of chromosomes?

Katyanochek1 [597]

Meiosis makes sperm and eggs. ... The result is 4 haploid daughter cells known as gametes or egg and sperm cells (each with 23 chromosomes – 1 from each pair in the diploid cell). At conception, an egg cell and a sperm cell combine to form a zygote (46 chromosomes or 23 pairs).

katrin2010 [14]

Answer:

An experiment that directly test the hypothesis.

Explanation:

Although there is quite a bit missing from Mary's scientific investigation, the thing that sticks out the most is the fact that Mary is missing an experiment. Mary's hypothesis states that people would fall asleep faster if their room color were to be painted blue. To prove that her hypothesis is true, Mary would need to conduct an experiment to see whether or not she was correct.
