1. 1 Water makes up between 70-90% of the weight of most life forms, and nearly all chemicals present in living matter are solub
boyakko [2]

Answer:

The correct model is D.

Note: The first attachment below shows the different models. The second attachment shows the correct structural model of the water molecule.

Explanation:

A water molecule is composed of one atom of oxygen and two atoms of hydrogen.

A water molecule is polar, i.e. it contains positively and negatively opposite ends. The polar nature of the water molecule is due to strong electronegativity of oxygen which results in an uneven sharing of the bonding electrons between oxygen and hydrogen. The oxygen atom attracts the shared electrons more to itself, thereby, it acquires a partial negative charge, while the hydrogen atoms acquire a partial positive charge.

The bond angle between the oxygen and hydrogen atoms is approximately 105°. Therefore, from the first attachment below, the correct model for the water molecule is D.

A man of unknown genotype has type B blood, his wife has type A blood (also unknown genotype). List ALL the blood types possible
shtirl [24]

Answer:

AB, aB, Ab

Explanation:

Man has blood type B so could be BB (homozygous dominant) or could be Bb (heterozygous)

Woman has blood type A, so she could be AA (heterozygous dominant) or Aa (heterozygous)

Now, we need to make a separate cross for woman with AA, man with BB and we get children of all AB

Then we can make another cross for genotypes Aa and BB, and we get AB and aB

We can continue this for AA,Bb and for Aa,Bb
