The answer to the question is B
Near the surface or the shallow water. Hope I helped
Darwin's theory of evolution by natural selection can explain how antibiotics are becoming defective because the bacteria that is trying to be fought off might have had a mutation making it more likely to survive. Once that surviving bacteria makes offspring most of the first generation will die from the antibiotic but soon all of their offspring will produce a resistance to that antibiotic.
<h2>Answer is option "B"</h2>
Explanation:
- Fossils are formed by unusal ways of minerals,energy and other substances. the sap solidifies and frames the semiprecious material called golden. In certain bits of golden the buried survives from living beings can be found. Volcanic ejections can shape fossils when creatures get caught in the hot debris streams. Right now, the fossil is a hole looking like an animal.
- Truth be told coal is the fossil record of entire timberlands; in any case, singular plant structures normally don't make due as the plant materials are compacted to short of what one-hundredth of their unique size. the hard part of plants are remain the fossil.
- So as to get fossilized, creatures must kick the bucket in a watery situation and become covered in the mud and residue.
- hence, the right answer is option B "Plant lived near the poles,but landmasses have drifted to current locations".
Answer:
- Independent variable: Car weight (car + block with a mass of 10 grams)
- Dependent variable: Speed (the time the car takes to descend the ramp)
Explanation:
As you can see in the question above, Shawn wants to check the speed that a car takes when going down a ramp, related to the weight of this case, that is, he wants to know the influence of the weight that the car presents, in its speed in going down a ramp.
In this type of experiment, we can consider the weight that the car presents as the independent variable. This is because independent variables are those that influence a result within the experiment. They happen without the influence of another variable and are factors that impose changes in the analyzed system.
The dependent variable, however, is the car's speed down the ramp. This is because the dependent variables are those that need and are influenced by the independent variable, to achieve a result that can be measured and analyzed.
