Antibiotic resistance in bacteria is the result of A) binary fission.
B) nitrogen fixation
C) genetic variation.
D) genetic engineering.

Answers

Answer 1

Answer:

Antibiotic resistance in bacteria is the result of genetic variation.

What is Genetic variation?

DNA sequence variations among members of a population are referred to as genetic variation. Sperm and egg cells, as well as somatic (all other) cells, are subject to variation.

Only variation that develops in germ cells can be passed from person to person and hence influence population dynamics and, in turn, evolution.

Genetic variety first appeared as a result of mutations. A mutation is a type of DNA sequence change that is permanent. When a mistake in DNA replication occurs and is not fixed by DNA repair enzymes, de novo (new) mutations take place.

Therefore, Antibiotic resistance in bacteria is the result of genetic variation.

The image shows a paramecium and a bacterium. One of these organisms is very good at rapidly adapting to environmental changes because it has the ability to take in stray genetic information from the environment. Which structure allows the organism to do this?

Answers

Genetic variation enables bacteria to adapt to changes in their environment. Since, bacteria reproduce asexually (binary fission), they can share genes (genetic transfer) via other mechanisms such as conjugation (exchange of genetic material through direct contact between two bacteria), transformation, and transduction(exchange of genetic material via bacteriophages).

Transformation is a process by which bacteria takes in DNA from its environment through the cell membrane.

Only some organs contain cells true or false

Answers

False; everything in your body is made up of cells.

FALSE ,The body's functions are conducted by organs. Each organ is a recognizable structure (for example, the heart, lungs, liver, eyes, and stomach) that performs specific functions. An organ is made of several types of tissue and therefore several types of cells (see Cells). For example, the heart (seeHeart) contains muscle tissue that contracts to pump blood, fibrous tissue that makes up the heart valves, and special cells that maintain the rate and rhythm of heartbeats.r body is made up of cells

Which best describes why Earth has day and night?Question 5 options:

Earth rotates on an axis.

Earth revolves around the Sun.

The Moon rotates on an axis.

The Moon revolves around Earth.

Answers

Answer:

Explanation:

The Earth rotates on a tilted axis. Since the Earth also moves around the sun, one part of its face will be exposed the sun's light, while the other part will be in darkness.

Because the Earth spins, for a certain number of hours, one face will be exposed to the sun, so that's day. However, after spinning for a while, that face will then be turned away from the sun, and will experience darkness, which is night.

Thus, day and night are caused by the Earth's rotation on its axis.

Hope this helps!

Final answer:

Earth experiences day and night due to its rotation on its axis. When a part of Earth is facing the Sun, it experiences daylight while the part not facing the Sun experiences night. This is different from the Earth's revolution around the Sun, which causes the change of seasons.

Explanation:

The best description of why Earth has day and night is that the Earth rotates on its axis. Imagine the Earth as a spinning top. One full rotation or one complete spin of Earth on its axis is what we understand as a 24-hour day. When a part of the Earth is facing the Sun, it experiences daylight, and when it is not facing the Sun, it experiences night. It's this rotation that gives us the cycle of day and night. This rotation is fundamentally different from the Earth's revolve around the Sun, which takes about 365.24 days and gives us our year.
