Which type of scientific statement is defined as a statement of fact that is generally accepted to be true and universal because
FinnZ [79.3K]

Answer:

C. Law.

Explanation:

A law is a type of scientific statement is defined as a statement of fact that is generally accepted to be true and universal because it has always been observed to be true.

Some examples of laws that are universally accepted include;

I. Law of Conservation of Momentum: it states that if objects exert forces only on each other, their total momentum is conserved.

II. Law of Conservation of Energy: it states that energy cannot be destroyed but can only be transformed or converted from one form to another.

III. Newton's First Law of Motion: also known as law of inertia, it states that, an object or a physical body in motion will continue in its state of motion at continuous velocity (the same speed and direction) or, if at rest, will remain at rest unless acted upon by an external force.

IV. Ohm's law: it states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.

V. The three (3) laws published by Kepler include;

a. The first law of planetary motion by Kepler states that, all the planets move in elliptical orbits around the Sun at a focus.

b. According to Kepler's second law of planetary motion, the speed of a planet is greatest when it is closest to the Sun.

Thus, the nearer (closer) a planet is to the Sun, the stronger would be the gravitational pull of the sun on the planet and consequently, the faster is the speed of the planet in terms motion.

c. The square of any planetary body's orbital period (P) is directly proportional to the cube of its orbit's semi-major axis.

Compare and contrast the modes of action of lipid-soluble and water-soluble hormones.
viktelen [127]

Answer:

Lipid soluble hormones:

Lipid soluble hormones are hydrophobic in nature and contains hydrophobic signals. Their receptors are present inside the nucleus and some are limited to cytosol as well. The binding of the receptor to its ligand stimulates the synthesis of new protein. The binding of hormone response element binds to the enhancer  region of DNA. Example: steroid hormones and thyroid hormones.

Water soluble hormones:

Water soluble hormones are hydrophilic in nature and contains hydrophilic signals. Their receptors are present on the cell membrane . The binding of the receptor to its ligand stimulates the signaling cascades mechanism. The binding of hormone to its receptor results in the activation of protein kinase and secondary messenger.

How do the organ systems function together in the human body?
earnstyle [38]

Answer:

Some body systems work together to complete a job. For example, the respiratory and circulatory systems work together to provide the body with oxygen and to rid the body of carbon dioxide. The lungs provide a place where oxygen can reach the blood and carbon dioxide can be removed from it. Some body systems share a common organ that performs more than one job.
