An individual with this karyotype would be described as A) an abnormal male with nondisjunction. B) a normal male with the expec
kaheart [24]
<h2>Answer:</h2>

The correct answer is option A which is an abnormal male with nondisjunction.

<h3>Explanation:</h3>

The karytope is the complete picture of chromosomes present in a cell of an individual.

It is used to study the chromosome number and abnormalities related with chromosome numbers.

Chromosomal nondisjunction is the consequence when the homologous chromosomes are not completely separated from each other during meiosis.

While chromosomal translocation is the crossing over of genetic material between two chromosomes.

Only chromosomal disjunction can be seen from the karyotype.

Which describes the scientific view's order of earth's first living things to the most recent?
hammer [34]
<span>The scientific view's order of Earth's first living things to the most recent is described by choice C. cyanobacteria, hagfish, crocodilians, giant ground sloths. Cyanobacteria have lived on the Earth since the Precambrian supereon. Actually, they first appeared in the Archean eon (4-2.5 billion years ago). Hagfish, as other jawless fish, appeared in the Paleozoic era (541-252 million years ago). Crocodilians appeared in the Cretaceous period (145-66 million years ago). Giant ground sloths, also known as megatherium, appeared in the Pliocene epoch (5.33-2.58 million years ago).</span>

Explain will water move in, out, or both if a cell is placed in a hypertonic solution​
STALIN [3.7K]

Answer:

<em>Water will move out of a cell.</em>

Explanation:

A hypertonic solution will have higher solute concentration and lesser solvent concentration. If a cell is placed in such a solution, then the concentration of the solvent will be more inside of the cell as compared to outside of the cell. As a result, the solvent will move out of the cell. If an excess of solvent is lost, the cell might shrink to dangerous levels.

Hence, from the above description we can justify that water will move out of a cell which is placed in a hypertonic solution.
