What are cytokinesis and mitosis?Mitosis is a cell division type that divides the parent cell and the genetic material into two alike daughter cells with the same chromosome numbers.
Cytokinesis is a process by which at the end of the telophase the cytoplasm of the cell starts dividing and results in the formation of the plate in plants and furrows in the animal, dividing the cell equally.
Thus, option "B" is correct.

Tom swatted Beth’s jump shot 25 M into the stands with a force of 100 n. how much work did he do
When Tom struck Beth’s jump shot 25m into the stands with a force of 100N, the work done by him is 2500J.
What do you mean by Work done?Work done may be defined as the process of transferring energy from one source to the other. It is the outcome of force and displacement.
From the above definition, W = F×d
W = 100N × 25m ⇒ 2500N/m

The motion of molecules and the transfer of energy decreases with increase in volume of the solution.
What is effect of volume in motion of particles?The volume of a solution is inversely proportional to the motion of the molecules of a substance.
An increase in volume results in a decrease in the motion of particles due to a decrease in the frequency of particles and thus, less energy is transferred.
Therefore, the motion of molecules and the transfer of energy decreases with increase in volume of the solution.

Oxygen and carbon combine to form different compounds. What type bond is formed between these two atoms?
options:
hydrogen
ionic
covalent
Answer:
C.) Covalent
Explanation:
Oxygen and carbon are both nonmetals.
A.) is incorrect because hydrogen bonds are only formed between hydrogen and either oxygen, nitrogen, or fluorine.
B.) is incorrect because ionic bonds form between nonmetals and metals. In this situation, you have two nonmetals.
C.) is correct because covalent bonds are formed between two nonmetals. A covalent bond will form because oxygen and carbon are nonmetals.
Answer:
Covalent
Explanation:
A covalent bond is formed when two non metals form, which means that's the answer. For the record, for hydrogen bonding Hydrogen obviously has to be present, and an ionic bond occurs between a metal and a nonmetal

A) The creation of carbon atoms
B) Physical Changes for carbon molecules
C) Both B & C
D) All of the above
Answer:
All of the above
Explanation:
Carbon atoms are created during the process of photosynthesis. During this process, plants will absorb carbon dioxide and sunlight to create energy, glucose, and other sugars. And for the physical changes of carbon molecules, carbon can undertake multiple changes overtime. Even though this element can be stored in the Earth for millions of years, it can be transferred in seconds from one object to another

Sayid listed some characteristics of waves in a chart. Part of his chart is shown.
A 1-column table with titled Characteristics of Waves. The column labeled Electromagnetic Waves has entries travel in straight lines, move only through matter, involve interactions with magnetic fields.
Which of these would correct Sayid's error?
Change the heading of the chart to “Mechanical.”
Replace “travel in straight lines” with “move in curved paths.”
Add “move due to particles bumping into each other” to the chart.
Change “move only through matter” to “move through space and matter.”
Answer:
Change “move only through matter” to “move through space and matter.”
Explanation:
Electromagnetic wave like light can travel thru both space and matter. Ever tried to shine a flash light thru a water bottle? The light passes thru the water and the bottle (both are types of matter: liquid and solid) and reaches the other side.
Ever see Suns ray enter your eyes? The light travels thru the vast empty space (our solar system) to reach earth.
Thus, electromagnetic waves can move thru both space and matter.
Electromagnetic waves have the ability to move through matter as well as through space. So the correct option is Option D.
What are the characteristics of Electromagnetic waves?An electromagnetic wave is a type of radiation that travels through space. Electromagnetic waves form when an electric field meets a magnetic field.
Electromagnetic waves do not require molecules to travel. Unlike sound waves, which travel through matter by smashing molecules together, electromagnetic waves cannot travel through a vacuum such as space. Instead, they can travel through the air, solid matter, and even space. This makes electromagnetic waves very useful for many technologies.
There are many different types of waves in the electromagnetic spectrum, ranging from radio waves that are as long as a building to gamma rays that are smaller than a nucleus of an atom.

Look at this diagram of sulfur. What is the most likely thing that will happen to complete the outer shell?
options:
donate 2 electrons
donate 6 electrons
accept 6 electrons
accept 2 electrons
Answer:
Accept 2 electrons
Explanation:
Elements are most stable when their valence shells are filled. Since sulflur lies within the third row in the p-block, it wants 8 valence electrons. However, according to the diagram, it only has 6 valence electrons. The simplest way to having a filled outermost shell is the one which involves the least amount of electrons being added or donated to the element. In this case, the fastest way to a stable element is by adding 2 valence electrons (6 + 2 = 8).

Which represents the cross between parent plants if one is heterozygous and has yellow-colored pods and the other is homozygous and has green-colored pods? yy ´ yy yy ´ yy yy ´ yy yy ´ yy
The cross between parent plants if one is heterozygous and has yellow-colored pods and the other is purebred and has green-colored pods is Yy×yy.
What is Heterozygous?Heterozygous may be defined as the existence of two distinguishable alleles at a distinct gene locus.
In this condition, Yellow is dominant over green i.e. Y>y. Heterozygous means the existence of two distinguishable alleles at a distinct gene locus. So, the genotype of one parent is Yy, while the other parent is purebred and has green-colored pods. Hence, the genotype is yy.
Therefore, the cross between parent plants if one is heterozygous and has yellow-colored pods and the other is purebred and has green-colored pods is Yy×yy.

A snow-covered mountain has a higher albedo than a dark-colored corn field. Therefore, it will reflect solar energy _____ than the field. (lower, more, less).
A snow-covered mountain has a higher albedo than a dark-colored corn field. Therefore, it will reflect solar energy more than the field.
Does snow have a high or low albedo?Dark surfaces absorb the rays from the sun (low albedo). Ice- and snow-covered areas have high albedo, and the ice-covered Arctic reflects solar radiation which otherwise would be absorbed by the oceans and cause the Earth's surface to heat up.
Why does snow have a high albedo?Freshly fallen snow reflects incoming solar radiation very well and therefore has a high albedo. New snow typically has an albedo of 0.96 to 0.98 in the visible and near-UV range (Grenfell et al., 1994), and 0.8 averaged over the entire wavelength spectrum.

What would happen over the several generations when typica moth and carbonaria moth are released into a pooluted forest are :
The typica moth population would decrease The carbonaria moth will have a reproductive advantage in the polluted forest Industrial melanismThe concept in this question is indutrial melanism because the carbonaria moth ( dark colored ) will have an advantage over the typica moth because it can easily camouflage itself from predators. While the typica moth ( brown colored ) can be easily spotted by predators and this will leed to a population decreas in the typica moth.
