Answer:

4. The A allele is dominant to the a allele.

Explanation:

In genetics, the dominant allele which is expressed when present in single or two copies is always written with an upper case letter. The corresponding allele whose expression is prevented in the presence of the dominant allele is written in the "lower case letter". This is called recessive allele. In the given genotype, one copy of "A" and one copy of "a" is present. This means that the allele written with upper case letter "A" is dominant over the allele "a". Nothing can be said about the genetic trait regulated by these two alleles of a gene.

For larger distances such as the distance between objects in the far reaches of our galaxy astronomers ensure in units of?

Scorpion4ik [409]

Answer:

Lightyears

Explanation:

When dealing with very large interstellar distances, astronomers do not use the regular miles, kilometers, or meters we are used to. This is because they are just too small to be used as a metric when measuring such large distances. As a matter of fact, the earthly number system will quickly be exhausted when trying to measure some of these interstellar distances.

Instead, astronomers make use of Lightyears. Lightyears are defined by the distance traveled by an object moving at the speed of light if it was moving constantly at that speed for one year.

This can properly be used to estimate interstellar distances. since its value is very large. 1 lightyear = 9,461,000,000,000 Km

If we say that our closest star is 9 lightyears away, we are saying that it will take an object moving at the speed of light 9 years to travel from that star to our planet.

With a medicine dropper, add a drop of pond water to the center of a clean glass slide?

Kisachek [45]

Pond water contains a variety of plant and animal life. While some are visible to the plain eye, others require a microscope to observe them. For example, there's bacteria, protozoa, hydras, algae, and arthropods. You will have the opportunity to see a number of microorganisms from both the plant and animal kingdom.
