What is polarity? Describe the polarity of water.

Biology

Water, which not only dissolves many compounds but also dissolves more substances than any other liquid, is considered the universal solvent. A polar molecule with partially-positive and negative charges, it readily dissolves ions and polar molecules. Hopefully this helped :D

a man with blood group A marries a woman with blood group O and their daughter has blood group O. Is this information enough to
Nonamiya [84]
This information is not enough to tell which of the traits-blood group A or O is dominant.
It is known that blood groups A and B are codominant, which means both will express if found together in a heterozygote. However, blood group O is recessive. But from this information, you can conclude that blood group O is dominant. Why is that so?
Let's imagine that father's genotype is AA and mothers' genotype OO and cross them:
Parents:               AA    x    OO
Offspring:      AO    AO   AO    AO
Since we have information that daughter has blood group O, we can conclude that O is dominant over A and mask it. This is not true! In this case, the daughter will have blood group A.

Mother's genotype surely is OO (because O allele is recessive, so to express a recessive trait both alleles must be recessive). But, the father cannot be AA, because it must give O allele to the daughter so she can have genotype OO and blood group O. So, the father's genotype is AO.  Let's take a look at that crossing:
Parents:         AO   x    OO
Offspring:   AO   AO   OO   OO
Thus, in this case, daughter can have genotype OO and blood group O.

Many different organisms live in Amanda’s garden. The diagram shows a simple food web of some of the organisms in her garden.
Alex787 [66]

Answer:

The snakes keep the mice from overpopulating, which could deplete their resources.

Explanation:

The mice and the moles are not competing against each other as they feed on different food. The problem is that if the mice population is not regulated, their very quick reproduction will cause overpopulation in very short space of time. The more mice there will be , the more food will be needed, so very soon the resources will be depleted, resulting in collapse of the mice population. This is where the snakes come in action, as they eat mice, so they are the ones that control and keep their population stable, thus not allowing the mice to overpopulate the area and destroy themselves.

Answer:

Alternation of generation with both sexual and asexual

Explanation:

In mosses, the dominant plant is called a gametophyte while in ferm the dominant is sporophyte. Gametes are produced by the gametophyte and fertilization occurs forming an embryo. The embryo develops into a plant called the sporophyte.
