Answer:

B)hydronium

Explanation:

This chemical structure is formed when an acid is disolved into water, as the cation (H+), which comes from the acid, cannot exist as such isolated in water (H20), hence the proton (H+) will be hydrated by a water molecule (H2O)

The union between H+ and H2O is due to the pair of electrons from oxygen and positive charge from H+

Answer:

H3O+ units are also known as hydronium ions. Hence the answer is option B.  

Explanation:

Hydronium ions is defined as ions that contains proteinated ions and it is present in all the aqua solutions. These ions are abundant in protons and they have less electrons in them. It is because they had donated electrons to their other forms which gives a positive sign to the ion.

Hydronium ion is produced when an Arrhenius acid is mixed with dihydrogen oxide. This iron is found in universe like in comets, interstellar things, etc.

Which represents the cross between parent plants if one is heterozygous and has yellow-colored pods and the other is homozygous
9966 [12]

The cross between parent plants if one is heterozygous for yellow pods and the other is homzygous for green pods - Yy yy., i.e., option A.

<h3>What is heterozygous?</h3>

The occurrence of different types of alleles is referred to as heterozygous condition.

A heterozygous genotype may consist of one normal allele and one mutated allele, or two distinct mutated alleles.

The missing options of the question are:

  1. Yy ´ yy
  2. YY ´ yy
  3. Yy ´ Yy
  4. yy ´ yy

The cross between parent plants if one is heterozygous for yellow pods and the other is homzygous for green pods - Yy yy.

Thus, the correct option is A.

Which statements correctly describe mutations in gametes and mutations in somatic cells?
ASHA 777 [7]

A mutation is a rare, accidental or induced modification of genetic information (DNA or RNA sequence) in the genome.


The consequences of a mutation vary according to the part of the genome affected. A mutation is said to be hereditary if the mutated genetic sequence is passed on to the next generation.

In multicellular animals, germline mutations can be transmitted to offspring, whereas somatic mutations do.


Somatic mutations do not affect cells intended for reproduction, so they are never hereditary:

* Post-zygotic mutations are the mutations that appear in the egg after fertilization. They are rarer and are expressed as mosaic in the individual concerned (the mutation will be present only in the daughter cells originating from the mutated embryonic cell).

* Mutations can appear throughout life on the DNA of any cell; they are then transmitted to the line of the daughter cells. These can, in some cases, become tumor cells and then form cancer.
