A polymer is made up of monomers. A monomer is a unit that occurs in repetitive chains. Lipids do not occur in repetitive chains, so they are not classified as monomers. Since they're not monomers, they can't make up polymers, either.

A dna replication bubble forms at a specific sequence of bases called the ___________. see section 15.3 (page 321) .
julsineya [31]

The answer is the origin of replication. This is where the replication bubble is formed. Two opposite replication forks (Y-shaped regions) of DNA are formed when the double helix is unzipped by DNA helicases. Transcription factors, polymerase III and primer then bind to the region to begin transcription.

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.

Which statement would be used in an argument against the use of human embryonic stem cells for therapy?
Marizza181 [45]

The statement 'obtaining embryonic stem cells for use in therapy requires the destruction of embryos' would be used in an argument against the use of human embryonic stem cells for therapy. It is a type of stem cell therapy.

<h3>What are embryonic stem cells?</h3>

The embryonic stem cells are cells obtained from embryos that have the property to divide and specialize into different tissues.

The embryonic stem cells can be differentiated in the laboratory for the development of specific cell lineages.

The therapy using embryonic stem cells involves the use of these types of cells and the destruction of an embryo.
