Answer: This is an extremely drug resistant bacteria that must have inherited genes against this drug resistant from a parent bacteria that was exposed to the drug or substance. The parent bacteria went through a mutation to survive this environmental pressure and transferred that gene or mutation to its offspring.

Through natural selection and horizontal gene transfer this bacteria is able to survive in the presence of a molecule that is supposed to kill it and has developed extreme resistance against.

How does the endocrine system control body processes? WORTH 20 POINTS
Sidana [21]

Answer:

The endocrine system is made up of glands that produce and secrete hormones, chemical substances produced in the body that regulate the activity of cells or organs. These hormones regulate the body's growth, metabolism (the physical and chemical processes of the body), and sexual development and function.

Explanation:

The endocrine system is responsible for regulating a range of bodily functions through the release of hormones.

Hormones are secreted by the glands of the endocrine system, traveling through the bloodstream to various organs and tissues in the body. The hormones then tell these organs and tissues what to do or how to function.

Some examples of bodily functions that are controlled by the endocrine system include:

metabolism

growth and development

sexual function and reproduction

heart rate

blood pressure

appetite

sleeping and waking cycles

body temperature

Endocrine system organs

The endocrine system is made up of a complex network of glands, which are organs that secrete substances.

The glands of the endocrine system are where hormones are produced, stored, and released. Each gland produces one or more hormones, which go on to target specific organs and tissues in the body.

The glands of the endocrine system include:

A student analyzed a viral genome and found that the genome had the following nucleotide composition.
lapo4ka [179]

Answer:

Option A) Double-stranded DNA

Explanation:

Note that the presence of thymine, a pyrimidine nitrogenous base in the genome indicates the presence of DNA.

Then, the summation of 28% adenine + 20% thymine + 35% cytosine + 17% guanine to yield 100% confirms that the DNA is double-stranded.

Thus, the structure of the viral genome is Double-stranded DNA.
