Based on this data and your knowledge of natural selection, which explanation best explains the trends seen in the data?

A. Individuals with thicker fur had a survival advantage in the cold environment, allowing these individuals to reproduce more often and create more offspring.
B.Individuals within this population of mammoths tend to only mate with individuals that have thick fur.
C.This population of mammoths appear to be in Hardy-Weinberg equilibrium since no allele frequencies are changing over time.
D.Individuals with thick fur migrated into the population of mammoths, increasing the proportion of these individuals.

PLEASEEE HELPPP MEEEE!!!!

Answers

Answer 1

Answer:

Individuals with thicker fur had a survival advantage in the cold

Explanation:

Answer 2

Natural selection means the process of changing the adapting the new environment. Based on the given data one can conclude that the individual with thicker fur had a survival advantage in the cold environment.

Why natural selection occurs?

Natural selection takes place due to 3 underlying reasons:

ReproductionHeredityVariation in fitness of organisms.

Due to these reasons, natural selection can leads to speciation.

As the individual are living in cold environment, they need to adapt the change in environment. So, individuals with thicker fur had a survival advantage in the cold environment, allowing these individuals to reproduce more often and create more offsprings.

Thus, option A is correct.

Answers

The correct answer is B. In the Northern Hemisphere, the polar jet stream separates colder air near the pole and warmer air to the south.

The jet stream is a geophysical effect caused by the large temperature difference between the north pole and the equator. Something similar also happens on a small scale. In summer, when night falls and the ground cools where the sun is gone, air blows from north to south across the boundary between warm and cold air. This is the refreshing evening breeze.

From the north, a jet stream generally supplies colder air than from the west or south. The jet stream also creates depressions with a warm front and a cold front.

Answer:: De-termination could offer experiences into development and normal assets that are at present inaccessible to us.

2: Compromised or harmed biological systems could be reestablished with the assistance of specific now-wiped out species.

3 In the event that  people  drove plant and creatures species into termination, maybe we owe it to these species to attempt to bring them back.

4 De-elimination could be a major advance forward for hereditary designing.

There are loads of valid justifications to bring back wiped out creatures. All creatures perform significant jobs in the environments they live in, so when lost species are returned, so too are the 'positions' they once performed. Wooly mammoths, for instance, were nursery workers. ... It very well may be something similar for other de-wiped out creatures, as well.

Zeroing in on de-elimination could think twice about by redirecting assets from protecting environments and forestalling more current eradications. It could likewise diminish the ethical load of annihilation and backing for imperiled species, sending the mixed signal that resuscitating a wiped out creature or plant is trifling

How and why does the surface of the earth change
of the earth has changed?

Answers

Answer:

How and why does the surface of the earth change

of the earth has changed?

It can be hard to describe change on the surface without bringing up the interior. Earth is a system of constantly changing interactions between interior, surface conditions, and external events.

Volcanoes bring up new material and even create land. The Hawaiian islands, for instance are a chain of volcanoes on the surface, but the underlying structure is a single magma plume. In a way, the entire chain of islands is a single volcano that breaks through different places as the crust moves over it.

On that note: plates. Earth is made of tectonic plates that constantly move. Some grind against one another, others collide, and some pull apart. Depending on direction and interaction, you get anything from mountains, to spreading valleys, oceans, and anything else you care to name. Mountains can almost be viewed as something akin to the ridges of build up ice on a window scraper.

Erosion by water, wind, sand, chemicals, and living things changes the surface too. Materials on the surface face an incredible number of forces breaking them down and dragging them away, even as those same forces in different places and situations deposit those materials in other places, building things back up.

“Stardust” is also a thing. Rocks, dust, debris, and all sorts of random, natural cra.,p is constantly hitting our atmosphere. Regardless of whether or not it stays mostly intact, some material breaks off, and most of it does tend to make it to the surface, adding tiny amounts of matter all the time. …of course something BIG enough hitting the surface can throw rocks and chunks of surface clear into space, so that’s a thing too.

Remember when I mentioned living things? Living things D.,IE! Gac.k! And when they do, they break down into organic gunk. Soil - the stuff we grow crops in - is basically minerals and dead things that are decaying into nutritious, yummy, dir.,t.

Weather changes things too. Rain erodes, but rain that soaks a rock, and then is frozen by low temperatures, breaks the rock. Too much rain can create flooding, which results in a lot of sediment moving downstream. Heat can dry things out, crack the ground, and even slowly cook one kind of soil into another. Lightning can make glass out of sand, snow can collapse weak ground, not enough rain can dry out ground that could si.nk down without the extra pressure, and too much rain can literally move mountainsides if enough water adds its weight to the rocks and dir.t.

It’s always changing, and there is always more complexity to go into when studying it. There’s seldom a single cause, or reason, or effect for anything.

Explanation:

Have a great day!

The surface of the earth is constantly changing.

Explanation:

Wind, water,and ice break down large rocks and move sediments on the surface. Some events, though, change earth's surface much more quickly. These include volcanic eruptions, earthquakes, and landslides.
