The correct Answer is B.

My explanation

A barred spiral galaxy is a spiral galaxy with a central bar-shaped structure composed of stars. Bars are found in between one third and two thirds of all spiral galaxies. Bars generally affect both the motions of stars and interstellar gas within spiral galaxies and can affect spiral arms as well.

If you were to classify the many breeds of dogs by morphology, what would be inferred regarding species?
SIZIF [17.4K]

All dog breeds would be regarded as one Species under the theory of reproductive isolation.

Breed vs Species :

A breed is a group of creatures of a species who have undergone selective breeding to develop some unique traits.

A species is a group of organisms that can interbreed to produce viable progeny.

Through a process of artificial selection, different breeds of a species are created. Natural selection is the process by which different species develop.

A scientist has a pea plant with yellow seeds. It has one allele for yellow seeds (Y) and one for green seeds (y).
Eva8 [605]

Answer:heterozygous

Explanation:

The genotype of an organism is its genetic makeup which is characterized by the presence of alleles of a gene.

The genotype can be broadly of two types :

1. Heterozygous - when an individual has 2 different variants of a gene known as alleles, then the person is said to be heterozygous for that gene.

2. Homozygous - if both the alleles of a gene are the same, then the person is said to be homozygous.

Since in the given situation you have two different alleles - yellow and green represented by Y and y, the individual is heterozygous.

Why can the complex sugar cellulose store more energy that the sugar glucose
adelina 88 [10]

Because they contain less "built-in" water.

Explanation:

When two glucose molecules 'decide' to bond, they lose a molecule of water:

<span>2<span>C6</span><span>H12</span><span>O6</span>→<span>C12</span><span>H22</span><span>O11</span>+<span>H2</span>O</span>

And this happens at every connection between glucose molecules, so in a long chain a lot of water is lost. The water does not contribute anything to the energy content of the compound.
