Gravitational force multiple choice
Answer:
Option B. The force would be quartered (factor of 1/4).
Explanation:
The gravitational force between two objects can be expressed with the equation:
By analyzing the equation, we can see that if we multiply both m1 and m2 by 1/2, the resulting new F would be lower by a factor of 1/4 (as 1/2 times 1/2 equals 1/4).
Thus the correct answer is option B.

Explain how a mutation has caused the Lactase Persistence gene in some people and not in others.
Answer:
It is a case of human niche construction
Explanation:
Lactase is an enzyme of mammals which is required to digest lactose. In humans (like in other mammals), lactase activity decreases during mid-childhood; although there are individuals which are still capable of producing this enzyme even during adult life, a trait known as 'lactase persistence'. Different mutations in the coding region of the lactase gene have been associated with lactase persistence in European, African and Asian populations. On the other hand, the niche construction theory states that the organisms, through their activities and choices, actively modify their own local environment by introducing novel selection pressures. Some examples of niche construction include, among others, alternation of nutrient cycling by plants or lactase persistence in humans. Lactase persistence can be defined as a case of niche construction because this trait was not only genetically inherited but also culturally transmitted through local environments shaped by ancestral populations, i.e., generated by niche construction or ecological inheritance.

Explanation:
biological macromolecules are organized into four main categories. What type of macromolecule contains phosphorus as part of a phosphate group?
1.) lipids
2.) proteins
3.) nucleic acid
4.) carbohydrates
Answer:
3.) nucleic acid
Explanation:
Biological macromolecules can be defined as a very large molecule (structure) that comprises of covalently bonded organic atoms and smaller molecular structures (monomers).
Biological macromolecules are organized into four main categories and these includes;
I. Lipids: these categories of biological molecules is mainly made up of fats and it is responsible for providing the body with long-term energy.
II. Carbohydrates: it is contained in energy-giving foods and it aids the functioning of the muscles, nervous system and other organs found in the body.
III. Proteins: it contains amino acids and it is responsible for maintaining the functioning of the body system.
IV. Nucleic acid: it comprises of deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) which are the genetic codes (blueprints) for living organisms.
Hence, the type of macromolecule that contains phosphorus as part of a phosphate group (sugar 2-deoxyribose) is nucleic acid.
From the biological macromolecules, Nucleic acids contains phosphorus as part of a phosphate group.
Nucleic acids are biopolymers, macromolecules, crucial for all known types of life. Nucleotides, which are the monomer components, make up their structure. a sugar with five carbons, a phosphate group, and a base with nitrogen. Deoxyribonucleic acid and ribonucleic acid are the two main types of nucleic acids.
Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are two types of nucleic acids that carry genetic information that is read by cells to create the RNA and proteins that allow living things to function.

1. Prokaryote is a simple cycle compared to eukaryotic. The prokaryote is a
simple cycle because of three reasons.
A.
B.
C.
Answer:
A. Small size.
B. A single cell or unicellular.
C.it has one chromosome which is not true and it is called plastid.
Explanation:
This is because prokaryote are unicellular organisms that lack nucleus and membrane bound organelles. The are smaller in size compare to eukaryotic, which have large surface to volume ratio. They lack mitochondria, Golgi apparatus, endoplasmic recticulum, e t.c. They have only one chromosomes which is not even a true one and it is called plastid. Examples of prokaryote include bacteria.

What increases as you move from the surface to the interior of the Earth?
Answer:
Heat/temperature
Explanation:
"There are three main sources of heat in the deep earth: (1) heat from when the planet formed and accreted, which has not yet been lost; (2) frictional heating, caused by denser core material sinking to the center of the planet; and (3) heat from the decay of radioactive elements." These give the core and a few of the outer layers of the earth more and more heat.

Under certain external conditions, a person will perspire a great deal. For which internal condition does this response primarily provide homeostasis?
Answer:
Abnormally high temperature
Explanation:
Sweating or perspiration is a homeostatic response to abnormally high body temperature. Evaporation of the sweat causes cooling of the body and this causes the temperature of the body to return back to normal.
When the setpoint temperature of the body is breached by being too high, the negative feedback mechanism kicks-in, and the sweat glands of the skin becomes activated. The body sweats, and the evaporation of the sweat from the surface of the skin causes cooling and a return back to the setpoint.
