Answer:

Quasi-experimental research design

Explanation:

A quasi-experimental research design is similar to an experimental research design. It involves the manipulation of an independent variable but without the random assignation of participants to groups. Maria's experiment manipulates the administration of calcium, but the participants are not randomly assigned to the age groups, as they are already five or ten years old before the experiment and thus cannot be randomly assigned.

If two vehicles on a three or more lane highway both want to change lanes into the same lane?
Butoxors [25]

If two vehicles on a three or more-lane highway both want to change lanes into the same lane, then “the vehicle on the furthermost right yields right-of-way to the vehicle in the furthest left lane.” Hence, Option B is correct.

<h3>What is a highway?</h3>

When an important public road is constructed by the government either on a self basis or via some construction company with the aim of building connectivity between cities or towns is known as a highway.

When vehicles are driven by people on these highways, there are various lanes made. The reason behind making lanes on highways is to specify to the general public that according to the speed limit one has to drive.

Thus, Option B is correct.

When are children stable in their gender identity nih?
Alina [70]
By the age of three children are usually able to identify boy and girl toys and know which toys are supposed to be theirs. Whether this has anything to do with gender identity is another question though since this behavior can also easily be explained by mob mentality and social conditioning that influence the young brain to give the answers that it thinks people want to hear. There is a good chance that many children sexual identities are shaped by the influence of those people around them and how they treat gender. for example young boys in many families are scolded for playing with dolls, if this case the child never really has a chance to form his own gender identity, because one is forced onto him by his environment. For many people this leads to a a questioning of ones own sexual identity later in life after realizing they have been living the life they were told to live and not the one that they actually related to.
