The introduction of livestock to an area leads to over-grazing that removes native grasse

Invasive species. Native grasses have evolved with the normally-occurring grazing organisms to achieve a level of reproduction which sustains the grasses despite the grazing. An invasive species disrupts this ecological balance that took millions of years to develop by eating the grass at a rate that exceeds the rate for the grass to re-seed itself and maintain its own population. The invasive species easily decimates the grass population.

This might be a case of high velocity blood spatter. This type of blood stain is most likely to be caused by a gun of a small calibre. The gunshot usually causes high velocity blood spatter or can be caused by other objects when high amount of force is exerted. The high velocity blood spatter are caused by force travelling at a speed of 100 feet per second or more which produces droplets of diameter less than 1 mm. Explosions may also cause such high velocity blood spatter.

coldgirl [10]

Answer:

Option A

Explanation:

Implicit memory is based upon previous experiences and is a non descriptive form of memory therefore it cannot be described in word. Explicit memory on the other hand is descriptive and is based upon logic, facts and reasoning.

Implicit memory is associated with Cerebellum, basal ganglia and motor cortex while explicit memory is determined by Hippocampus which is supervised by the cerebral cortex.

Hence, option A is correct

In pea plants, the allele for round seeds is dominant to the allele for wrinkled seeds. If a plant that is heterozygous for seed

Harman [31]

Answer:

50%

Explanation:

According to this question involving a gene coding for seed shape in pea plant, the allele for round seeds (R) is dominant to the allele for wrinkled seeds (r). This means that a heterozygous pea plant (Rr) will have a round seed shape.

If a plant that is heterozygous for seed type (Rr) is crossed with one that has only homzygous wrinkled seeds (rr), the following gametes will be produced by each parent plant:

Rr - R and r

rr - r and r

Using these gametes in a punnet square (see attached image), the following proportions of offsprings will be produced:

Rr, Rr, rr and rr

Rr = round seed offsprings

rr = wrinkled seed offsprings

Since 1 out of 2 offsprings has wrinkled seeds, 1/2 × 100 = 50% is the percentage of offsprings expected to have wrinkled seeds.

Fofino [41]

The Arctic Fox lives in the Arctic Tundra (more or less around Alaska, Iceland I think, and other places like that). During the winter, their fur is very thick and solid white (not always SOLID but generally speaking). During the summer and spring, their fur turns brown.

1. Of course, during the winter in those regions, it's going to be snowing and ice is going to be all over the ground. By having a white coat, they're able to blend in and hide from predators, such as the Arctic Wolf and Polar Bears. By turning brown, they'll be able to blend in with the dirt after the snow and ice melts, and again, hide from predators. For the other fox, their brown coat blends in with the dirt, trees, dead leaves, etc. and they'll be able to hide from prey and predators alike.

2. The Arctic Fox also has very thick fur during the winter, which allows it to survive the extreme temperatures. They also dig burrows in the snow for shelter in blizzards. This gives them the ability to survive natural disasters (at least one of them).

I can't think of a third one but these should give you a pretty good idea of how their adaptations help them survive. I really love the Arctic fox so I know quite a bit about them. I really hope this helps you.
