Answer:A) The ocean is hypertonic to the erythrocytes.

Explanation:cells shrink when placed in an hypertonic solution.

This shrinkage occurs does to the movement of water out of the cell and through the cell membrane.this phenomenon is called plasmolysis.

The movement of water out of this cell occurs through osmosis.osmosis is the movement of water from a region of high concentration of solute to a region of low concentration of solute, through a semi-permeable membrane.

In this case,sea water has a higher concentration of solute (hypertonic) and the blood cells has a lower concentration(hypotonic) .the cell membrane serves as the semi-permeable membrane and and a result water moves out of the cell

Match the rocks with the material they are made of. igneous rocks /sedimentary rocks /metamorphic rocks
Vlad1618 [11]

The answers would be:

Igneous Rocks - They are made from hot magma.

Sedimentary Rocks - They are made from weathered pieces of rock.

Metamorphic Rocks - They are rocks, small or large which reformed due to high temperature.

If you'd like to know more, read on:

Igneous rocks are formed when hot magma is cooled and then it hardens into a rock. The word igneous comes from the word, "ignis" which means "of fire. They can be formed beneath the Earth or on the surface.

Sedimentary rocks are formed from weathered pieces of rock. These pieces are called <u>sediments</u>. They can also be made out of other material. When these sediments settle, it continues to do so until so much sediment accumulate and they start to press down on each other. The sediments then start to go through compaction and sedimentation which for a sedimentary rock.

Metamorphic rocks form under heat and pressure. They are squeezed and shaped and go through <u>metamorphosis </u>or go through change. A metamorphic rock can be formed from any other type of rock as long as it goes through changes due to intense pressure and/or heat.

What is the phenotypic and genotypic ratio of a cross between 2<br> heterozygous green pea plants?
irga5000 [103]

Answer: 1:2:1

Explanation:

The genotypic ratio is 1:2:1 whereas, the phenotypic ratio is 3:1 in the monohybrid cross. 2. Dihybrid cross: It is simple defined as the cross between two pairs of contrasting characters or parental alleles. Pea shape and color are used to conduct the dihybrid cross test.
