Answer:

The given situation is an example of <u>cohort differences.</u>

Explanation:

A cohort study is a form of study that samples a group of people that performs a cross section at particular intervals through time. Such a group is called cohort and it shares a defining characteristic, generally the one which experiences a common event in a particular period like graduation or birth.

Example: studying the mathematical ability of two groups of adults born 50 years ago and 25 years ago and analyzing the cohort differences in the scores of the test.

Therefore,<u> the given situation is an example of cohort differences</u>

Where did Newton get the inspiration for his first law of motion? (site 3)
user100 [1]

Answer:

<em>By the fall of an apple from a tree.</em>

Explanation:

<em>The first law of Newton’s is the law of movement that address inertia and how gravitational forces works. The storie about how Newton found this law is in a biography “Memoirs of Sir Isaac Newton’s Life”(1752), written by William Stukeley, which mentions the apple anecdote: “After dinner, the weather being warm, we went into the garden, & drank thea under the shade of some apple trees… he told me, he was just in the same situation, as when formerly, the notion of gravitation came into his mind…. occasion’d by the fall of an apple, as he sat in a contemplative mood.”</em>

Bitter cassava is often preferred as a crop over sweet cassava because it produces higher yields (more pounds of cassava per hec
Goryan [66]

Here is the full question:

Bitter cassava is often preferred as a crop over sweet cassava because it produces higher yields (more pounds of cassava per hectare planted) in the presence of herbivores. Which of the statements poses a hypothetical relationship?

a. Plants produce chemicals to deter herbivores. Bitter cassava stores toxic compounds in its tissues. Bitter cassava should incur less damage, and therefore have higher yields.

b. Plants produce chemicals to deter herbivores. Bitter cassava stores toxic compounds in its roots. Because they are below ground, the roots are not eaten and the presence of toxic compounds does not contribute to higher yields.

c. Plants produce chemicals to deter herbivores. Bitter cassava expends energy on producing toxic compounds. The more toxic compounds a plant produces, the lower its yields.

d. Plants produce chemicals to deter herbivores. Bitter cassava requires additional nitrogen to make these compounds. The additional nitrogen that is used reduces the amount of nitrogen available for plant growth, and decreases yields.

Answer:

a. Plants produce chemicals to deter herbivores. Bitter cassava stores toxic compounds in its tissues. Bitter cassava should incur less damage, and therefore have higher yields.

Explanation:

Hypothetical relationship refers to an imaginary situation that signify a relationship between an object/subject with another object/subject. This hypothetical relationship tend to be unproven/not yet backed by scientific evidence.

Pay attention to the wording in option A

. . . .stores toxic compounds in its tissues. Bitter cassava<em><u> should</u></em> incur less damage . . .

That word indicates that the one who made the statement only assume that the cassava will receive less damage from the interaction. This can be used as an example of a hypothetical relationship.
