How does selective breeding support Darwin's hypothesis about evolution?

Answers

Answer 1
Answer: Over the year of evolution, only the strongest survived and reproduced. So, having this happen over millions of years, species got stronger and stronger. For example, if there were two species of monkey's, one with fangs, one without fangs. The species with fangs would survive, and soon all monkeys would develop fangs because all the monkeys without them would die and not reproduce. That's how the evolved into what animals are today.
Answer 2
Answer:

Answer:

It does not support his hypothesis but it gave him a clue about selecting desired characteristics. Replace the breeder by the opportunities that are in the environment and you have it.  Breeders depend on variations to deliver new characteristics. If reproduction did not vary between generations, breeders will not get any new characteristics

What type of unhealthy air pollution occurs when ozone near the ground mixes with other polluting gases

Answers

The Option B is correct.

When ozone near the ground mixes with other polluting gases, then air pollution results in smog.

Smog:

smog is a kind of air pollution, originally named for the mixture of smoke and fog in the air. Classic smog results from large amounts of coal burning in an area and is caused by a mixture of smoke and sulfur dioxide. In the 1950s a new type of smog, known as Photochemical Smog, was first described.
Smog. Im pretty sure smog is the only unhealthful air pollution on this list.

What characterizes a biome

Answers

A biome is an area classified according to the species that live in that location. Temperature range, soil type, and the amount of light and water are unique to a particular place and form the niches for specific species allowing scientists to define the biome.

What 2 characteristics determine a biome?

Biomes are large-scale environments that are distinguished by characteristic temperature ranges and amounts of precipitation. These two variables affect the types of vegetation and animal life that can exist in those areas.

What other factors might determine biomes?

Average annual precipitation and temperature trends, factors such as geography, geology, soil types, disturbances, and topography can also influence the biome of a region. is home to a unique array of living things. Humans have an impact on biomes and the biodiversity of organisms supported by each biome.

A BIOME is a major ecosystem spread over a wide geographic area, and characterized by certain types of flora and fauna, as determined by climate. Climate and soil determine the flora, which, in turn, largely determine what type of other organisms live in that biome.

Which of the following would be least likely to be part of an ionic bond?- calcium
- Carbon
- lithium
- Bromine

Answers

Answer:

Carbon is least likely to be part of an ionic bond.

Explanation:

  • Ionic bond is formed by the process of transformation of electron between two atoms.
  • In ionic bonds the charges of cations and anions are balanced.
  • For the atom of carbon to form an ionic bond it must transfer 4 electron or gain 4 electron from another atom, this is not likely to occur in the chemical reaction.
  • Hence carbon atom shares 4 electron so that it can have the configuration of noble gas.

Describe the flow of blood through the human body, including through each of the four chambers of the heart. Explain how the blood changes as it moves through various locations in the body.

Answers

Unoxygenated blood from veins enters the right atrium then it goes down to the right ventricle then out through the pulmonary artery to the lungs where it becomes oxygenated blood which then enters the heart through the pulmonary veins and it goes to the left atrium and then is pumped down to the left ventricle and out through the aorta to the arteries where it travels to different organs and becomes deoxygenated and then the cycle repeats itself.
