The surface water is naturally purified by soils that filters the water. The correct option option is D.
What is soil water filtration?Soil not only captures water, but it also filters it. Physical, chemical, and biological processes clean the water that flows into and through soil.
When pollutants carried by water become trapped in the small pores of the soil, they are physically cleaned.
Water is cleaned by physical, chemical, and biological processes as it passes through soil.
In addition to its physical filtration capacity, soil contains important biota that helps transform and decompose certain chemicals and other contaminants from soil, thereby aiding in the removal of these contaminants from water.
Groundwater is typically clean and safe to drink. Groundwater is usually free of microorganisms that cause disease because the soil on top acts as a filter.
Thus, the correct option is D.

If John and Sam both push on a boulder with a force of 30N, but in opposite directions, what will happen to the boulder?
Question 4 options:
The boulder moves towards Sam
The boulder moves away from John and Sam
The boulder moves towards John
The boulder will not move.
The boulder will not move, because the net effect of the force is reduced if two people apply the same force to the object, hence option D is correct.
What is the effect of the force?Force is defined as applying strength or energy to applying on the object cause it creates motion. It is not in any object force is applied to the object by another person.
If John and Sam both push on a boulder with a force of 30N, having no effect on the boulder because they are applying the same force boulder but in opposite directions.
If any force is applied to the object but in the opposite direction, the net force is the difference between them, so it reduces the net force.
Therefore, the boulder will not move, due to the net force being reduced if the same force is applied to the object in the opposite direction.

Which best explains why sexual reproduction produces greater variations among offspring? *
A The DNA come from two genetically different parents.
B The DNA cells from one parent that is genetically identical.
C The sex cells are produced by mitosis.
D The sex cells undergo self fertilization
Answer:
A The DNA come from two genetically different parents.
Explanation:
Everyone has different genetics. They are determined by sex cells that are produced by MEIOSIS NOT mitosis. Meiosis allows for genetic variation amoung offspring along with the genetically different parents.
The DNA come from two genetically different parents explains the best reproduction greater variations among offspring.
What is sexual reproduction?Reproduction is the act of one or more parents creating a new individual (offspring), frequently within the same species. It is among the characteristics of a living creature.
Sexual reproduction, we mean a process where two parents' genetic material is combined to create a child. When two haploid gametes combine, a genetically unique diploid child is produced.
The word "sexual" has a Late Latin etymology that stems from the word sexus, which means "of copulation or generation." The word reproduction is also derived from the Latin words re, which means "again," and productio, which means "creation." Alternative: syngenesis.
Therefore, The DNA come from two genetically different parents explains the best reproduction greater variations among offspring.

This is hard. pls help. Write an equation for cellular respiration. Write an equation for photosynthesis. How are these two equations related?
Answer:
equation for cellular respiration: C6H12O6 + 6O2 + 6H2O → 12H2O + 6CO2
equation for photosynthesis:: 6CO2 + 6H20 + (energy) → C6H12O6 + 6O2
Plants make their own food by photosynthesis. During photosynthesis a plant takes in water, carbon dioxide and light energy, and gives out glucose and oxygen.

According to the American Council of Exercise, overweight people have, on average, greater than 30% body fat. In graph B, what do you notice about the amounts of hydrogen and methane in subjects with healthy body fat percentage compared to subjects who were overweight?
Answer:
Subjects in the “normal” group had a normal amount of hydrogen, 20 ppm or less, and a normal amount of methane, 3 ppm or less. If subjects had greater amounts than the normal amount of hydrogen (≥20 ppm) detected but had less than the normal amount of methane (≤3 ppm), they were considered hydrogen positive (represented by the “Hydrogen Only” bar), while ≥3 ppm of methane detected but ≤20 ppm of hydrogen was considered methane positive (represented by the “Methane Only” bar). If subjects had greater than the normal amounts of both gases (≥20 ppm of hydrogen and ≥3 ppm), they were considered hydrogen and methane positive (represented by the “Methane and Hydrogen” bar).

Answer for #8:
Cold water is heavier than warm water, and because of that it sinks. Ice dissolving into the water cools the ocean, causing it to drown. This creates a wave by which cold water is drowning near the poles, which forces the water into the depths of the ocean, leading the entire ocean to swirl. This cold, thick water is then forced back up against the west shores of the continents where it can be warmed.
