Answer:
microscope's condenser
Explanation:
The microscope's condenser is a substage lens that concentrates light on the specimen.
<em>The condenser of a microscope is a structure that helps concentrate light rays from the light source to illuminate the specimen on the stage of the microscope. It is made up of a system of lens that converges the ray of light and an aperture diaphragm that can be used to control the amount of light that gets to the specimen on the stage of the microscope.</em>
<span>The answer would be: a) Frost-wedging happens when water freezes and breaks rocks.
Normally, the volume of a substance will become lower when the temperature drops but when water becomes ice it will expand. Water that freezes into ice can produce a high pressure from the expansion of their volume. If enough water fills a joint in a rock, the rock might get enough force to fractured or break. This will happens in the area that has a freeze-thaw cycle like in the polar climate.</span>
<span>Pancreatic proteases (such as trypsin and chymotrypsin) - which help to digest proteins.Pancreatic amylase - which helps to digest sugars (carbohydrates).<span>Pancreatic lipase - which helps to digest fat.</span></span>
Answer:
Explanation:
In facilitated diffusion, molecules diffuse across the plasma membrane with assistance from membrane proteins, such as channels and carriers. A concentration gradient exists for these molecules, so they have the potential to diffuse into (or out of) the cell by moving down it.
Answer:
2, only the moose with the largest feet
Explanation:
If the moose species developed larger feet, then the cause of it has to be for their survival. So the ecosystem they lived in had to make it so the larger feet were helpful. That crosses out 1 and 3. The problem said nothing about the moose having smaller feet so, the answer has to be 2.
I hope this helps :)
