The statement which is false about the intergumentary system is option D. "Keratin is the pigment responsible for skin color."
Even though the skin color of human beings is affected y different substances, the pigment melanin is responsible for it. Melanin is produced within the skin in cells known as melanocytes and it determines of the skin color of darker-skinned humans.
For instance, the skin color of those who have light skin is determined primary by the bluish-white connective tissue placed beneath the dermis and by the hemoglobin which circulates in the veins of the dermis.
Answer:
B) Destruction of Habitat
Explanation:
Given what we know, we can confirm that the correct option is D, which states that "<em><u>They are used by living things as the </u></em><em><u>main source </u></em><em><u>of </u></em><em><u>energy</u></em>."
<h3>What are carbohydrates?</h3>
- They are the primary source of energy for most cells.
- They are what we refer to as sugars.
- The main example of this is glucose.
- They are formed by monomers called monosaccharides.
Therefore, we can confirm that since carbohydrates are what we refer to as sugars, which include molecules like glucose and this is the main source of energy for most cells, option D is the correct choice.

This property of massive bodies to resist changes in their state of motion is sometimes called inertia. The Second Law of Motion describes what happens to a massive body when it is acted upon by an external force.
Newton was one of the most influential scientists of all time. His ideas became the basis for modern physics. He built upon ideas put forth from the works of previous scientists including Galileo and Aristotle and was able to prove some ideas that had only been theories in the past. He studied optics, astronomy and math — he invented calculus. (German mathematician Gottfried Leibniz is also credited with developing it independently at about the same time.)
Newton is perhaps best known for his work in studying gravity and the motion of planets. Urged on by astronomer Edmond Halley after admitting he had lost his proof of elliptical orbits a few years prior, Newton published his laws in 1687, in his seminal work "Philosophiæ Naturalis Principia Mathematica" (Mathematical Principles of Natural Philosophy) in which he formalized the description of how massive bodies move under the influence of external forces.
In formulating his three laws, Newton simplified his treatment of massive bodies by considering them to be mathematical points with no size or rotation. This allowed him to ignore factors such as friction, air resistance, temperature, material properties, etc., and concentrate on phenomena that can be described solely in terms of mass, length and time. Consequently, the three laws cannot be used to describe precisely the behavior of large rigid or deformable objects; however, in many cases they provide suitably accurate approximations.
Ribosomes have no membrane and have 2 sub units. Remember, stay in drugs, don't do vegetables, and eat your school.
