atoms

Answers

Answer: All substances are built from

compound

oxygen

Explanation:

All substances are built from atoms as atoms are the basic building blocks of matter and are the smallest units of a chemical element. The correct option is D.

Atoms form the basis of all compounds. The fundamental building blocks of matter, atoms are the smallest units of a chemical element that nonetheless retain that element's chemical characteristics.

Atoms from various elements combine chemically to produce compounds, however compounds themselves are not the basic building blocks.

Although oxygen is an element that is present in several substances, it is untrue to say that oxygen is the primary component of all substances.

Although metals are a specific kind of element, not all substances are made of metals. Thus, the most correct response is that all substances are composed of atoms.

Thus, the correct option is D.

What is the difference between prokaryotic and eukaryotic cells?

Answers

The main difference that separates prokariotic organisms from eukaryotic organisms is the organisation of the genetic material. Prokaryotes have a single chromosome that isn't separated by a membrane and it's called nucleoid. Eukaryotes have multiple chromosomes that are inclosed in a nuclear envelope(nucleus).

The only organelles present in prokaryotic cells are the ribosomes(70S) which differ from the eukaryotic ribosomes(80S). Eukaryotic cells have membrane bound organelles like the mitochondrion or Golgi aparatus.

Read each of the answers below carefully: Which statement best describes the cell cycle? a. Cells grow and develop during interphase. Cells reproduce during the mitotic phase. b. Cells grow and develop during the mitotic phase. Cells reproduce during interphase. c. The nucleus of the cell divides during interphase. The cytoplasm of a cell divides during the mitotic phase. d. The nucleus of the cell divides during the mitotic phase. The cytoplasm of a cell divides during interphase.

Answers

Answer:

a. Cells grow and develop during interphase. Cells reproduce during the mitotic phase.

Explanation:

Cell cycle refers to the series of processes that leads to the growth/development and division of a cell. The cell cycle uses MITOSIS for cell growth. Mitosis comprises of two distinct stages namely: INTERPHASE AND MITOTIC PHASE. The interphase is referred to as the resting phase of the cell in which the cell grows and develops.

On the other hand, MITOTIC PHASE is the stage where the actual division of the nucleus (karyokinesis) and cytoplasm (cytokinesis) generally called CELL DIVISION occurs. Therefore, the cell reproduces i.e. one cell forming two, in the mitotic phase.

The statement best describes the cell cycle - a. Cells grow and develop during interphase. Cells reproduce during the mitotic phase.

Answers

Answer:

skin

Explanation:

The skin is vital for our general health and well-being. In addition to acting as the body's first line of defense against bacteria and viruses, healthy skin also maintains fluid balance and helps regulate body temperature. She is very sensitive, she recognizes the slightest touch as well as pain.

As an outer layer that we can see and touch, the epidermis protects us from toxins, bacteria, and fluid loss. It consists of 5 sublayers of keratinocyte cells. These cells, produced in the deepest inner, basal layer, migrate to the surface of the skin. As they do so, they mature and go through a series of changes.

A male cardinal’s red color is an example of a trait affected by natural selection. The females of the species choose mates based on the vibrant colors of the males’ feathers. If females begin using different criteria than feather color when they choose mates, what would most likely happen to the color of the male cardinals over time?
increased variation in the shades of red because there is no advantage in one specific color
increased variation in the shades of red because the cardinals try different ways to impress the females
decreased variation in the shades of red over time because no form of the trait is advantageous
decreased variation in the shades of red after a single generation

Answers

Answer:

decreased variation in the shades of red over time because no form of the trait is advantageous

Explanation:

If the vibrant red feathers are no longer used to attract mates, then it is no longer useful to the males, so it will cease to exist.
