What is the DEPENDENT variable in this experiment? (Hint: What depends on the independent variable?)
Nutka1998 [239]
Could you give more information? For the most part, the dependent variable is what you’re recording. For example, if you wanted to see how plants would grow in different conditions, plant height would be the dependent variable. The height DEPENDS on the condition it was grown in. Hope this helps!

Do you think animals pollinate flowers and disperse seeds on purpose or by accident?
Allushta [10]

Answer:

Animals most likely pollinate by accident.

Explanation:

Deer for example, they may graze in the grass. The pollen/seeds could catch onto their fur--and later fall off into a different area when they walk away. They could also eat a plant, and the seeds end up in their feces. Bees for another example don't necessarily <em>mean</em> to pollinate, they just happen to pick up pollen/seeds when they land on a flower for honey.

Hope this helps :)

Eating potatoes with the skin as opposed to without the skin can increase dietary fiber intake. A medium-size baked potato weigh
KATRIN_1 [288]

Answer:

  • <em><u>There are 1.6g more of fiber in the the potato with skin than the potato with flesh only</u></em>

<em><u /></em>

Explanation:

In the internet, you can find that a regular potato (medium-sized) with the skin contains about 4 grams of fiber; and half that is  in the skin , thus a potato without skin contains about 2 grams of fiber.

In other site, I found that the source used to deal with this question states 4.2 grams of fiber for <em>White, Flesh and Skin (173 grams)</em> and <em>2.6 grams for Potatoes, Baked, Flesh Only (173 grams)</em>.

Therefore, using the second reference, the differnce in the amount of fiber, in grams,  for the potato with skin and the potato with flesh only is:

  • 4.2g - 2.6g = 1.6g

The answer is that there are 1.6g more of fiber in the the potato with skin than the potato with flesh only.

What type of environmental conditions do the camera systems need to withstand for three years?
nikklg [1K]

Cameras and video-shooters are essentially tough. They can withstand a lot, from insects to shark bites. However, in order to withstand being outside for such a long time of three years? That's a little tricky.

As we all know, the batteries can corrode if left in damp places, or if left in for too long. Therefor, this can't be damp. Nowadays, most cameras have plastic in various places, so leaving it somewhere hot could inevitably melt it. You don't want that. If your camera is left in the cold, (18°F, 10°C) then the batteries could be severely changed. If left in a cold place, the battery life could deplete by so much as half, so in very cold climates, you will very quickly run out of power.

In order for it to sustain 3 years, you will probably need to find a climates that is about 60°F (15.5556°C) in a drier location.

I hope this helped!
