True because Weathering is the process breakdown of materials through physical or chemical actions and Erosion occurs when weathered materials such as soil and rock fragments are carried away by wind, water or ice. Many forces are involved in weathering and erosion, including both natural and man-made causes.This will causes rocks to disintergrate
Answer:
42,5 mL
Explanation:
We need to use the serial dilution formula beacuse we start with a stock concentrate solution and we need to prepare a new less concentrated one.

<u>DF in the dilution factor, Vi is the initial volume and Vf is the final volume.</u>
The first step is to have the same measurment unit so we need to convert 345 µg to mg.
we know that 1 µg equals 0,001 g, hence:

now the final volume is 0,345 mg protein/ mL and the inital volume is 15mg protein/mL, both of them are in the same unit so we can use the formula


Now since the question said that we already have 1.0mL of the amylase stock solution we need to subtract that 1.0mL to the 43,5 mg protein/mL

So, we need 42,5 mL of diluting buffer if we want a final concentration of 345 µg protein/mL (0.345 mg protein/mL)
Answer:
The correct answer is - option III.
Explanation:
An experiment is scientific procedure to test a hypothesis and to demonstrate any scientific procedure to prove something. In high school laboratories there are experiments constitutes scientific methods that helps in demonstrate or prove or existence of something.
Extracting various pigments from the leaves of plants and identifying them by separating from it, is the best example of the high school laboratory experiment among all the options.
Thus, the correct answer is - option III.
if we wipe out an animals natural habitat, or introduce new wildlife the animals could die. This could cause a major problem in the areas ecosystem. That is what i know, and i think that major problems would happen, like to many of one species, which takes all the food from the other species, causing major problems, and even more animals to die.
