Answer:

It rusts

Explanation:

Iron is a chemical element that has the ability to RUST when exposed to air and water. Rusting is actually a prolonged chemical process or change that results when iron reactively combines with water and oxygen in the atmosphere to from hydrated (III) oxide in a process called OXIDATION. This compound is behind the color change of the metal.

According to this question, a nail made of iron will change after being exposed to the oxygen in the air over a long time by RUSTING via the oxidative reaction of the iron constituent of that nail with oxygen.

The structure of a human skin cell differs from that of a human muscle cell. The two cells most likely have different __________
AnnyKZ [126]

Answer:

The correct answer would be - functions.

Explanation:

The structure of the skin cells and muscle cells are different and have a different number of cell organelles on their role in the body. Skin cells are a special type of cells that keep on shedding and replaced by new ones therefore they need less energy and have many mitochondria.

In contrast, muscle cells have different structures as they need a high amount of energy to make movements and therefore have lots of mitochondria in the cell.

The two main phases of the cell cycle are the cytokinetic phase and interphase
Vitek1552 [10]

Answer:

Flase

Explanation:

The cell cycle has two major phases: interphase and the mitotic phase. During interphase, the cell grows and DNA is replicated. Usually the cell will divide after mitosis in a process called cytokinetic in which the cytoplasm is divided and two daughter cells are formed.

hope this helps

have a great day/night :)

horsena [70]

Answer:

Bacteria

Explanation:

Bacteria are a group of single celled organisms that are neither plants or animals.

Bacteria lack cell organelles such as the nucleus and the chlorophyll.

They can be found in many environments and most of them are adapted to survive in extreme environments such as hot-springs where the temperatures are extremely high.

Unlike the plant cell wall, bacterial cell wall has a layer of peptidoglucan which determines their shape. Their cytoplasm contains both DNA and RNA.

In a large population of plants, notches in the leaves are caused by a dominant allele N and lack of notches by a recessive alle
Jobisdone [24]

Answer:

C

Explanation:

If the population is in equilibrium, the allele frequencies will be constant.

There is nothing about the heritability of dominant or recessive alleles that make dominant ones any more likely by nature. This rules out choices A and B.

Genetic drift mentioned in D refers to alleles leaving a population. Nothing like this was mentioned in the question, so count that answer out.

C is the only remaining answer by process of elimination. It is also the most logical choice. Directional selection refers to a process of natural selection wherein extreme phenotypes (notched leaves, or non-notched leaves) are favored. In this case, there may be some external pressure causing notched leaf plants to be more evolutionarily fit, meaning that they survive long enough to reproduce more and increase allele frequency of the dominant allele.
