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.

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.

Question 10 options:
energy, water, sunshine, and protection
water, parents, a place to live, and air
oxygen, an outer covering, parents, vitamins
food, water, air, and a place to live
Answer:
1: Mold 2: Cells 3: do all jobs 4: bacteria 5: producing offspring 6: Taxonomy 7: Healing a broken arm 8:obtain energy, produce offspring, maintain their structure 9: soil (I think) 10: food, water, air, and a place to live
Answer:
1. lung.
2. cells.
3. do all jobs for survival.
4. bacteria.
5. producing offspring.
6. Taxonomy.
7. a cell dividing.
8. obtain energy, produce offspring, and maintain their structure.
9. soil.
10. food, water, air, and a place to live.
Explanation:
1. all of the other options are organisms, while a lung is an organ.
2. All living things are made of cells
3. All unicellular organisms must be able to perform all the functions necessary for life. Meaning do all the jobs needed for survival.
4. Bacteria is the organism listed that is able to cause an infection or contagious disease.
5. A fish laying hundreds of eggs is an example of producing offspring. While it could also be an example of maintaining structure, a fish cannot obtain energy by laying eggs. So, the best answer is producing offspring.
6. Taxonomy's definition is the branch of science concerned with classification, especially of organisms; systematics.
7. a cell dividing is maintaining structure. After growth, cell division by mitosis allows for continual construction and repair of the organism. The primary concern of cell division is the maintenance of the original cell's genome. So, this is the best option for the question.
8. The second option is wrong, because not every organism plays video games. The 4th option is wrong, because not every organism builds their own home. And finally, the first option is incorrect, because plants do not physically eat they obtain their energy through photosynthesis. So, the correct option is the 3rd one.
9. Soil is not needed for all living organisms, but the other options listed are necessary.
10. the second and third option are incorrect, because not every living thing needs a parent. The first option is incorrect, because not every living thing needs sunshine and it does not list the other necessary components. So, the correct answer is the last option. And a place to live can also mean an appropriate environment.
Using the dichotomous key, Which kingdom classification of the organism is described above?
A.
Fungi

Eubacteria
C.
Protista
D.

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.

C Most of the DNA regulating Matt’s eye color is inherited from his mother.
D The DNA regulating Matt’s eye color is a unique combination of both of his parents’ DNA.
Answer:
I think it's A or D because he had to get his eye color from his mother since it's not the same as his father or it could be a mix of two different colors like D says, sorry lol
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).
