Answer:

The law of conservation of matter and energy states that matter is neither created nor destroyed but conserved. They can only rearrange the matter and energy. For example, an oxygen atom will cycle through a living system.

What happens to salinity if the rate of evaporation is greater than precipitation? Why?

malfutka [58]

Answer:

Answer:

Explanation:

What happens when water's salinity increases?

A combination of high salinity and low temperature makes seawater so dense that it sinks to the bottom of the ocean and flows across ocean basins as deep, slow currents.

What happens to local salinity when evaporation rates increase?

Salinity is the saltiness of seawater. Salinity is measured by the concentration of grams of salt per kilogram of water. ... What happens to local salinity when evaporation rates increase: Rises 5.

How is salinity related to evaporation and precipitation?

Evaporation of ocean water and formation of sea ice both increase the salinity of the ocean. However these "salinity raising" factors are continually counterbalanced by processes that decrease salinity such as the continuous input of fresh water from rivers, precipitation of rain and snow, and melting of ice.

How does the brain control the endocrine system?

Makovka662 [10]

As the head organ in the body which controls, monitors, supervises and influences the different organ system in the body and of the individual -characteristics, personality, traits, cognition, perception, intelligence, sensation and motor responses. The brain controls the endocrine system by its part, located somwhere in the medial temporal lobe called the hypothalamus, the master gland of the body. The hypothalamus influences every gland secretion and hormonal function that preceeds and proceeds in the body of an organism -growth, drives, sex, survival and etc.

The hypothalamus sends sgnals from the different gland organs in the body that either exhibits or inhibits the activity of that particular gland releasing hormone.

When the term biceps, triceps, or quadriceps forms part of a muscle's name, what does it tell you about the muscle? the muscle h

tekilochka [14]

Answer:

The muscle has two, three, or four origins, respectively.

Explanation

A muscle is an organ composed of muscle tissue that contract to facilitate a particular movement
biceps,triceps and quadriceps are types of skeletal muscles since they use bones as levers
They differ in that; the biceps have two origins, triceps have three origins and quadriceps have four origin.
Bicep is a two headed muscle thus said to have two origins ,triceps have three muscle heads and therefore have three separate origin attachment point while quadriceps are made of four muscles heads hence have four origins.

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.
