Which pair of factors affects the force of gravity between objects? direction and distance mass and distance mass and shape shape and time

Answers

Answer:

It's B

Explanation:

Mass and distance affects the force of gravity between objects.

Thus, option B is correct.

What is force of gravity?

Force of gravity is defined as the force of attraction between any two objects in the universe.

The force of attraction depends upon the mass of the object and the square of the distance between them.

Mass is the total amount of matter contained by an object.More the matter of the object has, the more the mass.Weight of an object can be zero but mass of the object cannot be zero.

Distance is defined as the amount of space between two places or things. Measurement of distance are kilometer, inch, foot, yard.

Therefore,Mass and distance affects the force of gravity between objects.

Thus, option B is correct.

B. Faulting of sedimentary rock and erosion.

C. Volcanic ash buildup and faulting of rocks.

D. Folding and breaking of sedimentary rocks and erosion.

Answers

Answer:

D. Folding and breaking of sedimentary rocks and erosion.

The two basic geologic processes that contributes to the formation of folded mountain ranges are ; ( D ) Folding and breaking of sedimentary rocks and erosion

Folded mountains are formed by the collision of two or tectonic plates, the movement and collision is mostly caused by massive erosion.

Tectonic plates are formed by the breaking down of the earth's outermost layer into large rock slabs which lies on a molten layer of rock these large slabs are components/make up the  sedimentary rocks

Therefore the folding and breaking of sedimentary rocks caused by massive erosion leads to the formation of folded mountain ranges.

Hence we can conclude that The two basic geologic processes that contributes to the formation of folded mountain ranges are ; Folding and breaking of sedimentary rocks and erosion

Which two phrases describe a situation that will cause a stationary object to start moving?

A. a net force greater than 0
B. unbalanced forces
C. a net force equal to 0
D. balanced forces​

Answers

Answer:

A .a net force greater than zero

B. Unbalanced Force

Explanation:

A .When the resultant force on an object is zero, it will remain at rest if it is at rest, or continue to move in a straight line at a constant velocity if it is in motion. So , the answer will be a net force greater than zero .

B . An unbalanced force (net force) acting on an object changes its speed and/or direction of motion. An unbalanced force is an unopposed force that causes a change in motion. A net force = unbalanced force. So , the answer will be unbalanced forces .

What do animals do with the carbon dioxide produced in their cells during cellular respiration?

Answers

Answer:

Explanation:

During cellular respiration animal cells combine oxygen with food molecules to release energy to live and function. Remember that cellular respiration produces carbon dioxide as a waste product. ... They release the carbon dioxide into the air as a waste product. Plants help animals and animals help plants.

The carbon dioxide produced in animal cells during cellular respiration is considered a waste and must be disposed of accordingly.

The carbon dioxide generated from cellular respiration in animal cells must be disposed off the cell because their build-up can be toxic to the cell.

Being a gas, carbon dioxide is got rid of by diffusing out of the cell while the oxygen required for cellular respiration usually diffuses in.

When carbon dioxide is allowed to accumulate in the cell, it might affect other processes such as the partial pressure of oxygen in the cell, and so on.

Answers

Answer: D

Explanation: visible light makes up only a very very, very small portion of the entire electromagnetic spectrum

The true statement concerning visible light and electromagnetic radiation is considered to be - d. Visible light is a small portion of the electromagnetic spectrum.

The electromagnetic spectrum is the range of frequencies of electromagnetic waves or radiations. This spectrum also gives an idea about the wavelengths of electromagnetic radiations. The part of the spectrum on their higher to lower energy or frequency range from [tex]10^{4}[/tex] Hz to [tex]10^{18}[/tex] Hz are:

gamma raysX-raysultraviolet radiationvisible lightinfrared radiationradio waves.

The visible light is the very small part of the electromagnetic spectrum that ranges from the [tex]400*10^{14} Hz[/tex] to [tex]800*10^{14} Hz[/tex], Visible light is the light that the human eye can see.

Discuss how constraints related to biology and management affect the choice of a crossbreeding system. Please be descriptive.

Answers

Answer:

Some important constraints:  

-Plant breeding: autogamy and allogamy, self-sterility, etc  

-Animal breeding:  trait compatibility

- Breeding systems in general (i.e., both in plants and animals): barriers for sexual reproduction  

Explanation:

Crossbreeding systems consist of the breeding between two breeds in order to develop progeny with particular advantageous phenotypic traits. In-plant crossbreeding systems, it is imperative to have into account whether the plant is autogamous (reproducing by self-pollination) or allogamous (reproducing by cross-fertilization), because it will affect the fitness of the progeny resulting from these breeds. Moreover, the biological mechanisms of self sterility and compatibility must be also taken into consideration. In-animal breeding systems, it is important to have into consideration that phenotypic traits we desire to obtain in the progeny must be compatible between races. In addition, the barriers for sexual reproduction are also an important issue both in plant and animal breeding systems, it thus being impossible, for example, to get a breeding between Chihuahua and Great Dane dogs.

Jaden's father is not sensitive to poison ivy. Jaden is also not sensitive to poison ivy. Jaden's lack of sensitivity to
poison ivy is which kind of trait?
environmental
acquired
learned
inherited

Answers

Answer:

Jaden's lack of sensitivity to poison ivy may be an inherited trait.

Explanation:

The poison ivy poisoning is due to the essential oils of this plant, mainly uroshiol, causing a reaction in the skin characterized by intense itching, redness and even burns with flicthenes, manifesting as an allergic reaction of varying severity.

Some people may have a low sensitivity or be insensitive to uroshiol, which does not rule out the possibility that they may become sensitive at some point in their lives.

The fact that Jaden and her father are insensitive to poison ivy venom may be an inherited trait, determined by a resistance to the allergic reaction the plant produces.

Regarding other options:

    Environmental, acquired or learned traits, do not determine the resistance to certain hypersensitivity or allergy reactions, which depends on each person's immune response or sensitivity.

Answer:

inherited

Answer: D

Explanation:

Carbohydrates and nucleic acids are the two main classes of biomolecules which are involved directly in the process of digestion of maltose through maltase enzyme. Thus, the correct option is D.

What is Maltase?

Maltase is a an enzyme which belongs to the alpha-glucosidase enzyme family. These are found in the small intestine's brush bordered cells. The hydrolysis of the disaccharide maltose into two simple sugars such as glucose is catalyzed through the enzyme maltase.

Maltose is a disaccharide which is produced by the enzymatic hydrolysis of starch, which is a homopolysaccharide and this is catalyzed by the enzyme amylase. Maltose sugar is further hydrolyzed by the enzyme maltase to produce two molecules of d-glucose.

Therefore, the correct option is D.
