Answer:

The answer is C.

Explanation:

It is given that the formula of density is, ρ = m/v where m is the mass of object and v is the volume of object. By using this formula, you are able to find the mass of gold :

ρ = 19.3 g/cm³

v = 30 cm³

19.3 = m/30

m = 19.3 × 30

= 579 g

Two types of stressors that learners are likely to experience in a post school destination as a college or university or the wor
makvit [3.9K]

Answer:

financial stress and family stress

Explanation:

When learners go to college or a university, their family expects a lot from them especially when the parents are the ones who brought the learner to study. This causes stress on the learners. Choosing the major can also be stressful, especially when the family intercedes in the learner's decision. This also creates a financial burden on the learner, especially when the learner supports himself. So,<em> he has to balance studying while working.</em> If he has a scholarship, he has to maintain his grades in order to keep up.

In the same way, <u>a person who goes to the workplace is also expected by his family to provide them financially.</u> This creates a financial stress on his end. Besides this, he is also expected to make commitments especially when he has children. He needs to balance working while taking care of his kids and attending to their needs at home and in school. This is how family stress can affect him.

Which taxonomic group includes kingdoms and all other levels of taxonomy?
alexandr1967 [171]
The most probable and the most likely answer that you would get in asking this question would be domain.

As for stating it as a taxonomic group, it is more appropriate to refer to it as category, but there is no arguing that both words can be interchanged so just take that as a personal preference. Domain would be referred to in modern taxonomic category as the category that includes the kingdoms and all the other levels of the taxonomic hierarchy.
