What happens to the force of gravity on a person as he gets farther away
from Earth?
Answer:
As you move away from the Earth, the pull of Earth's gravity weakens. ... The bigger the object, the stronger the force of gravity it exerts.
Answer:
This force of gravitational attraction is directly dependent upon the masses of both objects and inversely proportional to the square of the distance that separates their centers. This means that as you move away from an object the gravitational force decreases.

Sorry if its hard to understand, i kinda get deep in the awnswer's but

What primary method does the cell employ to ensure gene expression only occurs when necessary?
Limited amounts of specific DNA
Phosphorylation cascade with multiple steps
Receptors that only fit specific hormones
Unique transcription factors made of carbohydrates
Answer:
Unique transcription factors made of carbohydrates
Explanation:
Gene expression refers to the way by which the genes which contain hereditary materials in the cells are converted to certain proteins. Gene expression is regulated to avoid the wastage of useful energy. Transcription allows the copying of genetic information from the DNA to the RNA.
Transcription factors can activate or deactivate a gene thus hindering its expression. Unique transcription factors help to regulate gene expression.
Answer: receptors that only fit specific hormones

Glucose molecules contain stored energy for plants. Glucose is made from carbon dioxide and water molecules during photosynthesis. What kind of energy do plants use to make glucose molecules? A Electrical B Sound C Light D Kinetic
Answer:
The correct answer is - C. light.
Explanation:
In plants, glucose is formed or produces by the process called photosynthesis, a process that uses light energy to produce glucose with the help of carbon dioxide and water.
In this process, light energy is converted into chemical energy stored in glucose or sugars. The process involves light energy, CO2, and water and produces, glucose, and oxygen as a by-product.
a reactant in cellular respiration
Answer:
Oxygen or Glucose
Explanation:
Oxygen and glucose are both reactents in cellular respiration.

A hydroelectric dam has heated a nearby body of water.
Answer:
Not Healthy
Explanation:
Because the Fact that you said "aquatic ecosystem" changes the statement. Even though that this dam is hydroelectric, It doesn't benefit Aquatic life very much. Garbage does not come from electricity. No matter how it is made. You may get toxic gases, But not garbage. The warm water can kill the fish who may need a stable condition if no mutations occur. It can attract new praetors or fungi also.

5. How do producers play a part in the recycling of matter?
A. Producers convert light energy into organic molecules.
B. Producers make glucose in the absence of light.
C. Producers break down glucose.
D. Producers break down the cells of dead plants and animals.
Answer of the following questions is given below.
Radiant energy is called EMR or electromagnetic energy. This is energy that is transmitted without the movement of mass. This energy is found in waves and is also called light energy. The light is made by the individual particles called protons. Hence the option B is correct. Aerobic respiration is the form of respiration that requires O² in order to generate energy. The full oxidation of nutrients. It produces large amounts of energy. Hence the option D is correct. The anaerobic oxidation glucose is broken down without the presence of oxygen. Instead of carbon dioxide water, lactic acid is made that leads to muscular cramps. Hence the option D is correct. A fungus is an example of a decomposer as the fungus derives nutrients b decomposing the matter. Hence the option C is correct. Producers play an important part in the recycling of matter as they convert the light energy into organic molecules. Hence the option A is correct.Learn more about the answer the list of the following question.

name the organ that is adapted for gaseous exchange in humans
Answer:
Lungs.
Explanation:
Lungs are the organs that are responsible for gaseous exchange in humans. The lungs absorb oxygen from the air that is required for the process of respiration while on the other hand, carbon dioxide is transferred from the cells to the lungs through blood because carbondioxide gas is a waste material that is produced during respiration so it can be removed from the body with the help of lungs..

What will be the results in the F2 generation after a monohybrid cross?
all recessive traits
3/4 dominant and 1/4 recessive
all dominate traits
1/3 dominant and 2/3 recessive
Answer: [tex]\dfrac34[/tex] dominants and [tex]\dfrac14[/tex] recessive.
Explanation:
Mendel's monohybrid cross is definied as
a genetic combination of two homogeneous genotypes.One is dominant(TT) to other (tt-recessive).Result in F1 generation: 4 dominant(Tt), 0 recessive (tt)
Result in F2 generation: 3 dominant(TT, 2Tt), 1 recessive (tt)
[If one T is present then we call it Tall (Donimant effect), if none then we call it dwarf]
The results in the F2 generation after a monohybrid cross: [tex]\dfrac34[/tex] dominants and [tex]\dfrac14[/tex] recessive.
Describe three other features of a bacterial cell.
Answer:
hope it helped
Explanation:
Bacteria are like eukaryotic cells in that they have cytoplasm, ribosomes, and a plasma membrane. Features that distinguish a bacterial cell from a eukaryotic cell include the circular DNA of the nucleoid, the lack of membrane-bound organelles, the cell wall of peptidoglycan, and flagella.
The features of a bacterial cell are the following:
Bacteria are a large group of prokaryotic microorganisms (devoid of cell nuclei) of various possible shapes and sizes.
They are essential in the decomposition processes of organic matter, necessary for the recycling of elements such as carbon or nitrogen.
They reproduce quickly and by asexual procedures, which consist of the replication of the progenitor cell in two exactly equal to it (binary fission).They are made up of a single cell without a cell nucleus, but with a nucleoid (an irregular region where the circular DNA of prokaryotes is found).They have a peptidoglycan cell wall that covers the cell outside the plasma membrane.Scattered throughout the bacterial cytoplasm are ribosomes (in which protein synthesis takes place) and there are also often plasmids (small non-chromosomal DNA molecules).Some bacterial cell also have capsules, a rigid protective structure that is outside the cell wall and flagella to move (if they are mobile).Therefore, we can conclude that bacteria are a large group of prokaryotic microorganisms (devoid of cell nuclei) of various possible shapes and sizes.
