Runoff is the water source that becomes polluted as it travels over the earth. Therefore, option (D) is correct.
What is a runoff?Runoff refers to the water that flows over the surface of the earth, such as rainwater, snowmelt, or irrigation water. As runoff flows over the land, it can pick up pollutants such as chemicals, fertilizers, pesticides, sediment, and animal waste, which can then enter rivers, lakes, and other water bodies, making them polluted.
Polluted runoff can also cause soil erosion, harm aquatic life, and contaminate drinking water sources. Therefore, it is important to manage runoff properly by using practices such as rain gardens, bioswales, or green roofs that help absorb and filter runoff, reducing its potential to cause pollution.

Summarize what happens during the light reactions of photosynthesis.
It is during these reactions that the energy from sunlight is absorbed by the pigment chlorophyll in the thylakoid membranes of the chloroplast. The energy is then temporarily transferred to two molecules, ATP and NADPH, which are used in the second stage of photosynthesis.
During the light reaction of photosynthesis, chlorophyll absorbs light and converts this energy into chemical energy in the form of ATP and NADPH.
What is the light reaction of photosynthesis?
Light reaction is the first stage of the photosynthesis process in which the light energy is converted into chemical energy in the form of molecules of ATP and NADPH. The protein complexes and the chlorophyll pigment helps in the production of NADPH and ATP.
These reactions occur within the specialized membrane discs within the chloroplast organelle which are called thylakoids and involve three main steps which are: Excitation of photosystems by the absorption of light energy. Production of ATP by an electron transport chain. And, Reduction of NADP⁺ and the photolysis of water.

The two major cell types in a sponge's tissues are
collar cells and epithelium.
O collar cells and amoebocytes.
amoebocytes and oscula.
epithelium and oscula.
Answer: B. collar cells and amoebocytes
The collar cells have a funnel like collar and a flagellum. Collar cells whip their flagella to make water go through the sponge. Then the water brings nutrients and oxygen, while while also taking out waste and carbon dioxide.
Amoebocytes first deliver nutrients from choanocytes to the other cells, giving rise to eggs. Then they bring phagocytized sperm from choanocytes to eggs.
In sponges, the major cell types are collar cells and amoebocytes. Collar cells help capture and digest food, while amoebocytes handle nutrient transport and differentiation into other cell types. Option b is correct.
Collar cells have whip-like flagella that create water currents and trap food particles with their collars, which they then digest. Amoebocytes, which move through the mesohyl in an amoeba-like manner, have multiple functions including transporting nutrients from collar cells to other cells, generating eggs for sexual reproduction, and differentiating into various specialized cell types such as collencytes and lophocytes, which help maintain the structure of the mesohyl.Complete question as follows:
The two major cell types in a sponge's tissues are
a. collar cells and epithelium.
b. O collar cells and amoebocytes.
c. amoebocytes and oscula.
d. epithelium and oscula.
As altitude increases, what happens to the spacing between the particles?
Answer: As altitude increases, the spacing between particles increase.
Explanation: There is less gravity when altitude increases to compact the particles together and particles are more free flowing to move around. Therefore the particles aren't as close together, increasing the amount of space in between them.
In which situation would artificial insemination most likely be used over other forms of treatment?
OA.
A woman's ovaries do not release any eggs.
OB.
A man's testicles have not properly descended, lowering sperm count.
OC.
There is a blockage in the fallopian tubes.
OD.
The mucus that helps the sperm travel to the uterus is too thick.
Artificial insemination is most appropriate for situations where a man has a lower sperm count due to undescended testicles. It is a form of assisted reproductive technology (ART) that can help overcome male factor infertility by using concentrated sperm.
Explanation:In the context of assisted reproductive technologies (ART), artificial insemination would most likely be used over other forms of treatment in the case where a man's testicles have not properly descended, lowering sperm count (Option B). This is because artificial insemination can utilize sperm that have been collected and concentrated to increase the chances of fertilization when low sperm count is an issue. In cases where a woman's ovaries do not release any eggs, blockage in the fallopian tubes, or thick uterine mucus, other forms of ART such as in vitro fertilization (IVF) or surgical intervention may be more appropriate.
Treatments for infertility are highly dependent on the underlying cause. When the issue is related to sperm production or the availability of sperm, artificial insemination is often the first line of action. In contrast, for blockages or issues with egg release, surgical procedures, hormonal treatments, or advanced procedures such as IVF may be recommended.

the air particles are different in her colder
math classroom?
(A) They move faster on average.
B They are vibrating.
© They have less average energy.
D They move more freely.
Answer: they are vibrating
Explanation: During conduction, heat is transferred through the vibration of molecules in a substance. As something gets warmer, it begins to increase the vibration and movement of the molecules that it consists of
Final answer:
In the colder math classroom, the air particles c) have less average energy and therefore move slower compared to the warmer science classroom, where particles move faster due to higher kinetic energy.
Explanation:
Luciana notices that the air in her science classroom is much warmer than the air in her math classroom. The difference in the temperature of the air can be explained by the behavior of the air particles. In the colder math classroom, the c) air particles will have less average energy compared to the warmer science class. Air particles in a warmer environment move faster on average due to higher kinetic energy. Thus, as the particles in the math classroom are part of a colder environment, they move slower than those in the warmer science classroom.

Students treated a population of bean plants with fertilizer. They observed that these plants, on average, were taller than another population of the same kind of bean plants that were not treated with fertilizer. These observations lend support to which of the following conclusions?
A. Not all plants respond to fertilizer the same way.
B. Fertilizer can affect the growth of bean plants.
C. Survival of bean plants is dependent on fertilizer.
D. Only fertilizer can make bean plants larger.
Answer:
B
Explanation:
Because the excessive use of fertilizer can affect the growth of the bean plant
Final answer:
Observations where treated bean plants grew taller than untreated ones support the conclusion that (option B) fertilizer can affect bean plant growth.
Explanation:
Students observed that bean plants treated with fertilizer were taller on average than those not treated with fertilizer. This observation lends support to the conclusion that (option B) fertilizer can affect the growth of bean plants. While it is possible that not all plants respond to fertilizer in the same way, the data provided specifically shows that the treated bean plants were taller. This suggests that fertilizer has a positive effect on growth, at least for this type of bean plant. It does not, however, support the conclusion that survival is dependent on fertilizer or that only fertilizer can increase plant size, as this would require further testing and data.
