I think that these are A climate changes because they both got fur to match the snow/winter climate
I know it's not C cause this has nothing to do with food, and i don't think it's B either, so I think the best answer choice would be A

I  think it would be climate, because God gave the rabbit and the fox, the ones said in the question, white hair to blend in with the snow. Though do believe that they have more of a brownish type color in the summer and spring, maybe fall. So I think its (A) Climate

Bone fractures in which the bone protrudes through the skin are called
sergejj [24]

Answer:

The correct answer will be- compound fracture.

Explanation:

Bone fracture is the breaking of bone due to accidents, sports injuries, falls, osteoporosis and low bone density.

The fracture should be of various types depending on the degree but a type of fracture where a fractured bone protrudes out from the skin is known as an open fracture or compound fracture. The open fracture can also be a case of a medical emergency as it could lead to osteomyelitis, a type of bone infection.

Thus, the compound fracture is the correct answer.

Help please! Describe the process of natural selection and how it affects hummingbird populations.
Kipish [7]

<span>Natural selection has 4 processes.</span>

<span>Individuals looks different and have different characteristics from another within their own species (genetic variation). Some characteristics suits better for the environment, which has to be passed on from one generation to the next. The humming birds with long bills will mate with those that have that too so they'll produce offspring with long bills. </span>

<span>The second process is over production of offspring. The humming birds produces lots of offspring but only a few survives. </span>

<span>Another factor of natural selection is struggle for existence, which leads to differential survival and reproduction. There are environmental pressures, like not having enough space or food, for example, humming birds compete fiercely for resources like nectar. Natural selection will favor individuals that are more efficient at getting nectar and natural selection will result in changes in wing shape which can allow them to fly longer distance and affect the length and shape of bill for them to drink nectar. Little changes may affect how well they feed and survive. Those who are the fittest survives and are most likely to reproduce and pass on their advantageous genes to their offspring. If the long bills are more advantageous and can survive better in a particular environment, then overtime, those with short bills will disappear because they can't survive and the entire population would have long bills.</span>

Why does the presence of high concentrations of salts in soil pose a problem for plants? Select all that apply. If taken up by t
GenaCL600 [577]

Answer:

If the salts are not filtered from the transpiration stream, they can damage the plant.

If excluded by the root, the salts can make it harder for the root to extract water from the soil.

Explanation:

When soil has high salt concentration, it becomes very difficult for the plant to take in water. Sometimes the problem becomes so peculiar that plant becomes completely unable to take in the water and hence they wilt and die. This happens even when the surrounding soil has sufficient water but remains un-drawn by the plants due to its high osmotic potential resulting due to highly concentrated salt solution. Therefore, more energy and effort is required by roots to extract water from salty sand.

Also if the salt concentration with in the plant increases, it remains there and causes damage

Hence, correct options are

If the salts are not filtered from the transpiration stream, they can damage the plant.

If excluded by the root, the salts can make it harder for the root to extract water from the soil.

Which refers to the sum of all the forces that act upon an object?
Charra [1.4K]

Answer:

Net force

Explanation:

Net force is the vector sum of forces acting on a particle or body. The net force is a single force that replaces the effect of the original forces on the particle's motion. It gives the particle the same acceleration as all those actual forces together as described by the Newton's second law of motion.
