Which process best explains how antibiotic resistance in bacteria can occur?

Answers

Answer 1

Answer:

Antibiotic resistance is a consequence of evolution via natural selection. The antibiotic action is an environmental pressure; those bacteria which have a mutation allowing them to survive will live on to reproduce. They will then pass this trait to their offspring, which will be a fully resistant generation.

Everything in the universe was created when the big bang occurred and the universe is expanding. So, the correct option is (A).

What is Big Bang Theory ?

The Big Bang theory is an attempt to explain what happened at the beginning of our universe. Major discoveries in Astronomy and Physics have explained that our universe actually had a beginning. Before that moment there was nothing and after that jump there was something which is our universe.

According to the widely known theory, our universe sprang into existence as "singularity" which goes back around 13.7 billion years ago. Singularities are basically zones which flout our knowledge of physics. They are assumed to be present at the core of "black holes."

Black holes are regions of enormous gravitational pressure. The pressure is assumed to be so extreme that finite matter is actually squished into infinite density (a mathematical concept which truly boggles the mind). These zones of interminable density are called "singularities."

Thus, everything in the universe was created when the big bang occurred and the universe is expanding. So, the correct option is (A).

If DNA code consists of only four nitrogenous bases, how can it produce so much variety among
organisms of the same species?

Answers

Explanation:

I tnought this will help you

If DNA code consists of only four nitrogenous bases, still it produces so much variety among organisms of the same species with the help of Codons and amino acids sequences.

What do you mean by Nitrogenous bases?

Nitrogenous bases may be defined as a molecule that contains nitrogen and possesses the chemical properties of a base. The nitrogenous bases that are found in DNA are Adenine (A), Guanine (G), Thymine (T). and Cytosine (C). Uracil (U) is present instead of Thymine in RNA.

There is a total of 4 nitrogenous bases that are found in DNA and RNA. Each codon codes with the help of three nitrogenous bases. So, total variations = [tex]4^3[/tex] = 64.

But there are only 20 amino acids that are commonly known. Some codons are stop codons, they do not code for any amino acids. While some codons code for the same amino acids.

Therefore, If DNA code consists of only four nitrogenous bases, still it produces so much variety among organisms of the same species with the help of Codons and amino acids sequences.

1. Which systems (2) are primarily responsible for movement of the body

Answers

Answer:

The correct answer is -muscular system and skeletal system.

Explanation:

The skeletal system and the muscular system work together to move the body or body parts. Different types of tissues form the muscular system that and their action on bones controls the movement of the body in vertebrates.

Tendons are tough muscles that attach with the bones and joints allow the movement by contraction of muscle that helps in moving bones from joint. Muscle normally acts by contracting and relaxing in pairs.

If there weren't alleles for different traits, but rather only one version of a gene for different traits, how would humans be different?

Answers

Answer:

Humans would look exactly alike

Explanation:

An allele which is a variation of a gene which expresses a particular trait(Phenotype).

For example, if humans have a gene for eye color but has different alleles for the color being black or brown for example, their phenotypes are different since the alleles are different.

But, if the alleles for the eye color are all the same, the eye color and every other phenotype would be the same. So, there would be no variations in eye color, height, color of skin etc. So, all humans would thus look alike having one set of genes for the different traits.
