Answer:

The sea star could be called a(n) keystone species.

Explanation:

The concept of keystone species was introduced by zoologist Robert T. Paine, in 1969. <u>A keystone species has a fundamental role in influencing an ecosystem, helping maintain the structure within an ecological community. The abundance or lack of the keystone species will determine the abundance or lack of other species as well.</u> It is common to use lions or wolves as examples of keystone species. If they disappear, certain animal populations that are usually hunted by them will prosper indiscriminately. That will drastically change the ecosystem, perhaps even leading it to its collapse. As we can see, the sea star describe in the passage is responsible for controlling the mussel population. The sea star is, therefore, a keystone species, preventing the overcrowding of mussels.

kogti [31]

Answer:

d.

Explanation:

Based on the information provided within the question it can be said that the the mostly likely change from this scenario would be that the selection has led to decreases in the size of fish at the age of reproductive maturity. This because if only the smaller fish are able to escape the nets, then those smaller fish need to have reproduced in order for the population to remain the same.

Who wrote the Kansas-Nebraska Act?
alina1380 [7]

Answer:   Senator Stephen A. Douglas of Illinois and President Franklin Pierce.

Context/details:

The Kansas-Nebraska Act enacted by Congress in 1854. It granted popular sovereignty to the people in the Kansas and Nebraska territories, letting them decide whether they'd allow slavery.  In essence, this made the Kansas-Nebraska act a repeal of the Missouri Compromise of 1820, which had said there would be no slavery north of latitude 36°30´ except for Missouri.

After the passage of the Kansas-Nebraska Act, pro-slavery and anti-slavery settlers rushed into Kansas to try to sway the outcome of the issue, and violence between the two sides occurred.  The term "bleeding Kansas" was used because of the bloodshed.

Describe the four basic steps of problem solving. What is the first basic step of problem​ solving? Choose the correct answer be
nadya68 [22]

Answers:

What is the first basic step of problem​ solving?

<em>B. Understand the problem. </em>

What is the second basic step of problem​ solving?

<em>B. Think about the context of the problem.</em>

Explanation:

In order to start attending to a problem, first one must understand what the problem is and who the people involved are; it is not possible to formulate a solution with no prior information from a situation that needs to be solved.

Subsequently, analyzing the roots of the problem  (the causes that led to an outcome) is essential to understand not only the background of the issue at hand, but it also aids in the formulation of alternative solutions as a next step of the solving process.

After executing these steps, choosing a single solution from an already defined set and implementing it is what follows and finishes the process.
