Answer:
Regarding wild boar, the fact that is best supported by the evidence provided is wild boars have established successfully mostly in areas with warm climates.
Explanation:
The wild boar (Sus scrofa) is a mammal from Africa, whose capacity to adapt to the environment is high. However, it is usually found in warm climates where it has a good supply of water and food.
According to the description of its distribution on the map, the states where it is found —predominantly Texas, California and Florida— verify the fact that they can be found mostly in warm climates, where they have found an ideal environment for their development..
About the other options:
- <u><em>Wild boars were brought to the United States by humans</em></u><em>. This is true, but it is not a fact that can be deduced from the information on the map.</em>
- <u><em>Wild boars have quickly spread through the United States</em></u><em>. The map does not show this information.</em>
- <u><em>Wild boars have a high reproductive rate and no natural predators</em></u><em>. The map does not show this information.</em>
Answer:
Population studies look at factors for one individual species.
Explanation:
In a garden, there are multiple species of plants growing. You could study different factors of each population, which is just all the individuals of one species in an area. For example, you could study how adding fertilizer affects the growth of tomato plants. To do this, you would have some tomato plants in the garden that have fertilizer added to the soil and some that don't. At the end of a certain period of time, maybe a month, measure the plants, find the average height and compare their growth. This is just one example, but there are lots of different things you could study.
Answer:
Penguins in general are distributed close to each other to be able to withstand the extreme cold, characteristic of the ecosystems they inhabit. They also group together to incubate their eggs.
They perform a series of coordinated movements that help them fight low temperatures, being careful to drop the egg.
The correct answers are evolution, genetic mutation and selection.
The early ancestors of horses showed the pressence of digits and now the modern horses have hooves in their limbs. There could be many reasons for the pressence of hooves horses.
These could be due to the genetic mutations, which could have changed the shape of the digits in the limb. Sudden change in DNA can cause mutation and this mutation can change the phenotype of the horse.
There are chances that evolution took place over a period of time that changed the character in the horse.
Natural selection can also be one of the reason for the change in the phenotype of the digits on the limb of the horses.
