Answer:
Natural selection is the process through which populations of living organisms adapt and change. ... Natural selection can lead to speciation, where one species gives rise to a new and distinctly different species. It is one of the processes that drives evolution and helps to explain the diversity of life on Earth.
Natural selection affects the evolution of species in that some species go extinct, while others thrive and grow in population. It also can effect food sources of omnivores and carnivores where the animal they were preying on has gone extinct or lower in population.
How is surface water naturally purified?
A:freezing water destroys impurities
B:evaporation leaves impurities behind
C:sediments precipitate out
D:soil filters the water
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.

Paramecia that live in freshwater have contractile vacuoles, while those that live in salt water do not. Why do you think this is the case?
Answer:
water enters by osmosis, vacuole is used to pump out excess water.
Explanation:
Paramecia that live in freshwater would have contractile vacuole because they will need to get rid of excess water unlike those that live in salt water.
The vacuole primarily functions to get rid of excess water from the cell.
Freshwater is hypotonic to the cytosol of paramecia. Thus, water will always enter the paramecia cells by osmosis. If the excess water is not excreted from the cell, turgidity will result and the cell may burst.
On the other hand, salt water is likely hypertonic to paramecia cells. Thus, instead of having vacuoles for water excretion, a mechanism would have to be put in place so as not to lose too much water to the surrounding salt solution. In other words, a vacuole would be totally redundant in the hypertonic solution.

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.

-global warming
- Temperatures
- ocean currents
-Climate
Answer:
it always going to be hot
Explanation:
Answer: Ice in the North and South Pole triggers the movement of ocean currents by starting a motion called the global conveyor belt. When water freezes in these areas, the water surrounding the newly formed ice decreases in temperature and becomes saltier. This results in an increase in density, so the water sinks to the bottom of the ocean floor where it becomes a cold current. Afterall, the water has to move somewhere so it travels horizontally to spread out over the surface of the earth. Warm water then takes its place and moves to the North. One event such as water freezing in the North and South Pole has resulted in something called the global conveyor belt.

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).

Matt’s eye color is different from his father’s eye color. Which statement best explains this occurrence? *
A The DNA regulating Matt’s eye color is identical to his mother’s DNA.
B Most of the DNA regulating Matt’s eye color is inherited from his father.
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.

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.
