Answer:
Reduce or stop the production of energy molecule i.e ATP
Explanation:
Proton is an essential ingredient to carry out light reactions successfully and the proton requirement is fulfilled through the proton gradient formed along the membrane. A chemical that blocks the flow of electrons thereby hindering the flow of proton will adversely affect the electron transport chain reactions thereby causing reduced/no conversion of ADP to ATP.
<h2>
Liver cell Vs Nerve cell</h2>
Explanation:
- b. liver cells can reproduce while the nerve cells cannot.
Liver cells , the fundamental units of liver are called hepatocytes. Hepatocytes secrete bile that helps in digestion by emulsifying fats. Hepatocytes are capable of dividing and they can regenerate damaged parts of the liver.
In contrast,
Nerve cells, the fundamental unit of nervous system are neurons. Neurons are longest cell of the human body and they contain a cell body and a long axon. Neurons conduct nerve impulses. Neurons are incapable of dividing and hence once damaged neuron cannot be replaced.
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.
Maya is pregnant and the doctor should tell her about the
condition of preeclampsia that this condition <span>can affect other
organs in the mother's body. It can cause kidney damage, liver failure,
neurological symptoms, such as severe headaches, seizures, and fluid on the
lungs and the reason behind this is may be a substance released from placenta.
And due to this the fetus may not get the nourishment and oxygen it needs for
growth. </span>
Answer:
C) Scrubbers remove sulfur from the smoke of coal power plants.
Explanation:
Well most scrubbers in North America (U.S) coal plants are used to remove sulfur emissions from coal and lessen the formation of acid rain.
