<em>Hi there, I come in behalf of jcherry99,</em>

So, first question -

This shouldn't be that much of an issue, since we have the text to help us out, but I'll try breaking it up into more simpler words:

The placenta is incide the uterus, where the baby starts forming. As you might already know, babies do not eat while they're inside woman's bellies:

So how do they feed?

They feed throught the umbilical cord.

So why is the placenta there? Why would the baby want anything apart from food?

The placenta, instead of trading food with the baby, regulates temperature, supplies it with nutrients, exchanges gas with the mother (which the mother later exchanges with the environment) and gets rid of waste.

And, food is not everything for a baby that is in the urge of developing complex muscles, bones, etc.

Second "question" -

I do not actually know what I'm supposed to do, since there is no question. But I can tell you this - the information contained in part B is correct:

The amnioic sac provides babies with a liquid which allows him to move freely in the uterus, which is very helpful. But, note that he doesn't start moving randomly, he is always in a fetus or similar-to-fetus position.

Hope it helped,

Rachael wants to test how sunlight impacts plant growth over time. She will add varying amounts of light to different sets of pl
Mrrafil [7]

Answer:

Independent variable: varying amounts of light

Dependent variable: plant growth

Explanation:

The variable, which are factors that can be altered, in an experiment can either be independent or dependent. An independent variable is one in which the experimenter manipulates or controls in order to bring about an outcome. For this experiment conducted by Rachel, the independent variable is the VARYING AMOUNT OF LIGHTS.

The dependent variable is the variable that responds to changes of the independent variable. In other words, the dependent variable is the outcome of manipulating the independent variable. Hence, the dependent variable is dependent on the independent variable. For Rachel's experiment, the PLANT GROWTH is the dependent variable because it is what responds to changes in amount of light (independent variable).

D is obviously not the correct answer as Social Media is typically fairly biased while B is able to be edited by the public.
