Answer 2
1. When fertilizer ends up in waterways, the fertilizer gets carried to larger bodies of water. The added nutrients from the fertilizer creates excessive growth of algae, creating algal.

2. Eutrophication is what a water based ecosystem does when too much nutrients are added to it. it’s mainly caused by two nutrients, phosphorus and nitrogen. The biggest problem in eutrophication are algal blooms.

3. At the mouth of the Mississippi River there is a dead zone. Due to algae using up all the oxygen, aquatic organisms can not survive there. Things that can help prevent dead zones are cutting down on fertilizer use and preserving wetlands.

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.

Answers

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.

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.

1. Plants on land have taken up approximately 25 percent of the carbon dioxide that humans have put into the atmosphere. The amount of carbon that plants take up varies greatly from year to year, but in general, the world's plants have increased the amount of carbon dioxide they absorb since 1960.

2. Animals that eat other animals get the carbon from their food too. Carbon moves from plants and animals to soils. When plants and animals die, their bodies, wood and leaves decays bringing the carbon into the ground. Some is buried and will become fossil fuels in millions and millions of years.

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?

Answers

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).

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

Answers

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.
