Why can’t a virus reproduce on its own?

monitta

Answer:

<h3>Viruses can only replicate themselves by infecting a host cell and therefore cannot reproduce on their own.</h3>

<h3>At the most basic level, viruses consist of genetic material contained within a protective protein coat called a capsid; the existence of both genetic material and protein distinguishes them from other virus-like particles such as prions and viroids.</h3>

<h3>They infect a wide variety of organisms: both eukaryotes (animals, fungi and plants) and prokaryotes (bacteria).</h3>

<h3>A virus that infects bacteria is known as a bacteriophage, often shortened to phage.</h3>

<h3>The study of viruses is known as virology, and those who study viruses are known as virologists.</h3><h3 /><h3>It has been argued extensively whether viruses are living organisms.</h3>

<h3>Most virologists consider them non-living, as they do not meet all the criteria of the generally accepted definition of life.</h3>

<h3>They are similar to obligate intracellular parasites as they lack the means for self-reproduction outside a host cell, but unlike parasites, viruses are generally not considered to be true living organisms.</h3>

<h3>A primary reason is that viruses do not possess a cell membrane or metabolise on their own - characteristics of all living organisms.</h3>

<h3>Examples of common human diseases caused by viruses include the common cold, the flu, chickenpox and cold sores.</h3>

Which of the following statements best describes the role of hormones in the body? Hormones send chemical signals throughout the

il63 [147K]

Answer:

Hormone production and release are primarily controlled by negative feedback. In negative feedback systems, a stimulus elicits the release of a substance; once the substance reaches a certain level, it sends a signal that stops further release of the substance. In this way, the concentration of hormones in blood is maintained within a narrow range. For example, the anterior pituitary signals the thyroid to release thyroid hormones. Increasing levels of these hormones in the blood then give feedback to the hypothalamus and anterior pituitary to inhibit further signaling to the thyroid gland, as illustrated in Figure 18.14. There are three mechanisms by which endocrine glands are stimulated to synthesize and release hormones: humoral stimuli, hormonal stimuli, and neural stimuli.

Explanation:

Hyperthyroidism is a condition in which the thyroid gland is overactive. Hypothyroidism is a condition in which the thyroid gland is underactive. Which of the conditions are the following two patients most likely to have?

Patient A has symptoms including weight gain, cold sensitivity, low heart rate and fatigue.

Patient B has symptoms including weight loss, profuse sweating, increased heart rate and difficulty sleeping.Humoral Stimuli

The term “humoral” is derived from the term “humor,” which refers to bodily fluids such as blood. A humoral stimulus refers to the control of hormone release in response to changes in extracellular fluids such as blood or the ion concentration in the blood. For example, a rise in blood glucose levels triggers the pancreatic release of insulin. Insulin causes blood glucose levels to drop, which signals the pancreas to stop producing insulin in a negative feedback loop.

Hormonal stimuli refers to the release of a hormone in response to another hormone. A number of endocrine glands release hormones when stimulated by hormones released by other endocrine glands. For example, the hypothalamus produces hormones that stimulate the anterior portion of the pituitary gland. The anterior pituitary in turn releases hormones that regulate hormone production by other endocrine glands. The anterior pituitary releases the thyroid-stimulating hormone, which then stimulates the thyroid gland to produce the hormones T3 and T4. As blood concentrations of T3 and T4 rise, they inhibit both the pituitary and the hypothalamus in a negative feedback loop.
