An invasive species can be any type of a living species, like a plant, an amphibian, fish, insect, bacteria, or fungus, which is not local to an ecosystem and leads to harm. They can possess harm to the surrounding, human health, or even the economy.

These species possess the tendency to evolve and reproduce briskly, and spread antagonistically, with the capacity to cause harm, they are labeled as invasive.

An essential element that makes various species invasive is an absence of predators in the new environment. Thus, an introduction of a predator species would likely help to imply a check in the growth of invasive species.

Hence, the correct answer is option A.

<span>The answer is A. Invasive species are species that thrive unregulated in an introduced environment/ habitat and affect the biodiversity of the environment. They boom unchecked mostly due to lack of a natural predator. Therefore, introducing a predator will limit their growth. </span>

Water that contains 2 mg oxygen per liter or less is termed hypoxic, since at that concentration many aquatic aerobic organisms
GaryK [48]
Global and local climate change also makes marine ecosystems more vulnerable to lower oxygen levels (hypoxia). Aquatic organisms cannot survive without the presence of dissolved oxygen in the water.
When the climate is warmer, the surface water warms up more quickly and its density becomes lower than that of the underlying waters. However, it is the mixture of waters of different depths that helps to oxygenate the deeper waters. If the surface water is warmer and less dense, it mixes less well with the more dense bottom waters.  As a result, the oxygen content will be lower in some places (deeper places for example).
At oxygen levels below 30%, species that do not tolerate hypoxic conditions must migrate to other geographic areas. If they can not migrate, their survival may be threatened.

6. A scientist measures the circumference of acorns in a population of oak trees
melisa1 [442]

Answer:

6. 2 cm

8. Greater than 2 cm and less than 2 cm

Explanation:

Complete Question

6. A scientist measures the circumference of acorns in a population of oak trees and discovers that the most common circumference is 2 cm. What would you expect the most common circumference(s) to be after 10 generations of stabilizing selection?

-2 cm

-Greater than 2 cm or less than 2 cm

-Greater than 2 cm and less than 2 cm

-Can't tell from the information given

8. Refer to question 6, but this time answer what you would expect after 10

generations of directional selection.

-2 cm

-Greater than 2 cm or less than 2 cm

-Greater than 2 cm and less than 2 cm

-Can't tell from the information given

Solution -

6. In an stabilizing selection, the average trait of a given population is favored over extreme values. Hence, it can be said that one specific trait is over presented in a given population. For example – uniform human birth weight, number of eggs a bird lay etc.  

Here in this case if most common circumference is 2 cm , then the tree population will try to have this trait as a stabilizing trait.  

Thus, option A is correct

8. In a  directional selection, the genetic variation decreases as per the environmental change. And hence the average trait will not be selected. Instead traits either higher or lower the average values will be preferred.  

Thus, option C is correct

Answer:

The correct answer is - observation.

Explanation:

Scientists like Si-Ling Chi, Aristotle, and Mary Anning developed  various scientific processes and made discoveries that shaped the history of the world. such discoveries are discoveries related to silkworms and how to make cloth from their cocoons by Si-Ling Chi, developing the scientific method by Aristotle and  Contribution to the field of paleontology greatly by Mary Anning.

All these scientists had a different type of skill and ability and one of the skills they had a strong power of observing the things or phenomenon work and many more other aspects of the scientific process.
