Savatey [412]3 years ago

<span>The answer is a graduated cylinder.

Graduated cylinders are used for volume measurement. To determine the volume of irregular shaped tool, such as a metal bolt, the displacement method is useful. Therefore, the graduated cylinder is filled with water. The metal bolt is then placed into the cylinder. It will displace the water, so the difference in the volume, before and after the bolt is placed, is actually the volume of the metal bolt.</span>

If a homozygous black bull is mated with a homozygous white cow and the calf is gray, this could be an example of ___________. H
givi [52]

Answer:

Incomplete dominance

Co-dominance

Explanation:

Gregor Mendel discovered the principles that governs heredity, in which one of them is that an allele called DOMINANT allele, is capable of masking the expression of its variant allele called RECESSIVE allele in a heterozygous state. However, there has been genetic scenarios contrary to this his LAW OF DOMINANCE.

One of those Non-mendelian pattern of inheritance is a phenomenon called INCOMPLETE DOMINANCE, where an allele does not mask the expression of another completely, instead their combined state produces a third intermediate phenotype that is different from both parents. This is the case of the homozygous black bull mated with a homozygous white cow to produce a grey calf. The grey phenotype is an intermediate phenotype of both the black and white colours that forms due to incomplete dominance.

Another genetic scenario is called CO-DOMINANCE, where one allele is neither dominant nor recessive to the other allele, but instead both phenotypes becomes simultaneously expressed in the heterozygous offspring. In this case, the black bull and white cow were mated to form a heterozygous calf with both black and white spots.

When is being genetically identical to the parent an advantage for organisms? Question options: When many offspring are needed i
nevsk [136]

Asexual reproduction is a form of reproduction in which the number of chromosomes or the fusion of gametes is not altered.

Being genetically identical to the parent is advantageous for organisms when the environment changes fast, and reproduction is needed.

A gamete (a reproductive cell with one set of chromosomes, like an egg or sperm) combines with another to form a zygote, eventually developing into an organism of cells with two sets of chromosomes. Sexual reproduction is a type of reproduction that involves this complex life cycle (diploid).

The advantages of sexual reproduction are numerous. Several instances include:

more genetic variation

immunity against contagious diseases

fewer genetic diseases

Evolutionary fitness has increased

Why do you think increasing vegetation slows the rate of erosion? <br> please help :]
lutik1710 [3]

Answer:

I'm pretty sure it stops erosion because the roots of the plants hold the soil, so that the soil doesn't fall away as quickly.
