A population is a group of individuals of the same species. According to the theory of natural selection, what is likely to happen to a population when a change occurs in its environment (for example, the amount of rainfall decreases or the temperature increases)?
A.All of the individuals would try to develop new traits so that they could survive and reproduce in the changed environment. B.Some of the individuals would try to develop new traits so that they could survive and reproduce, and the other individuals would die. C.Because all individuals of the same species have the same traits, one individual would never have an advantage over another in its population.They would either all survive or all die.D.The individuals that have traits better suited to the changed environment would be more likely to survive and reproduce than those with less suitable traits.

Answers

Answer:

The answer is D.

Explanation: As everyone knows, "survival of the fittest" is a common thing. When an environment is disturbed or has some changes, the effects vary from one species to another and the ones who have traits that can help get through or adapt to these changes will most likely survive.

What would happen if you put dna from another organism into a strawberry with the dna removed.

Answers

Answer:Have you ever wondered how scientists extract DNA from an organism? All living organisms have DNA, which is short for deoxyribonucleic acid; it is basically the blueprint for everything that happens inside an organism’s cells. Overall, DNA tells an organism how to develop and function, and is so important that this complex compound is found in virtually every one of its cells. In this activity you’ll make your own DNA extraction kit from household chemicals and use it to separate DNA from strawberries.

How is Yellowstone National Park affected by the supervolcano that lies beneath it?

Answers

Answer:

If another large, caldera-forming eruption were to occur at Yellowstone, its effects would be worldwide. Such a giant eruption would have regional effects such as falling ash and short-term (years to decades) changes to global climate. Those parts of the surrounding states of Montana, Idaho, and Wyoming that are closest to Yellowstone would be affected by pyroclastic flows, while other places in the United States would be impacted by falling ash (the amount of ash would decrease with distance from the eruption site). Such eruptions usually form calderas, broad volcanic depressions created as the ground surface collapses as a result of withdrawal of partially molten rock (magma) below. Fortunately, the chances of this sort of eruption at Yellowstone are exceedingly small in the next few thousands of years.

The air over the sand is warmer than the air over the water because sand heats up faster than water. This difference in temperatures makes the air over the sand less dense than the air over the water so it rises.

How are the tides affected by Earth's rotation?

Answers

Answer:

During low high tides, the Earth itself is pulled slightly toward the moon.  High and low tides are caused by the moon. The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. These bulges of water are high tides.

Please mark Brainliest  :)

Explanation:

Answer:

Explanation:

Earth's oceans, other bodies of water, and to a much lesser extent land respond to the moon by bulging and dipping as the moon revolves around Earth. The sun also plays a role in the formation of tides, but a much smaller one. Tides move around Earth as bulges in the ocean. As the ocean bulges toward the moon, a high tide is created. The high tide on the side of Earth facing the moon is called the high high tide. The high tide caused by the bulge on the opposite side of Earth is called the low high tide. (A low high tide may be understood as the moon's tidal force pulling the planet—not the ocean—toward it.)

2. Explain the movement of initial energy from the sun

Answers

So the sun gives energy to the producers (plants) and then the primary consumers eat the producers getting their energy from the plants. Then, the secondary consumers eat the primary consumers getting their energy from the primary consumers and finally the tertiary consumers eat the secondary consumers getting their energy from them. Therefore, the entire energy pyramid starts with the sun!

People miss many things when they are trying to get through storms.  Fog is really hard to see through so Amelia could have easily missed it.  Clouds could have covered her view of the island so she would have missed it.
