Answer:
Without an oxygen atmosphere very few things could live on the early Earth. Anaerobic bacteria were probably the first living things on Earth. The early Earth had no oceans and was frequently hit with meteorites and asteroids.
Explanation:
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.
I world say national park. because farming could be taking away from the biodiversity. where as the national park planning would be trying to help the biodiversity.
This is true that The mutation rate would also be higher.
<h3>What is mutation?</h3>
A mutation is a change in the nucleic acid sequence of an organism's, virus's, or extrachromosomal DNA's genome. DNA or RNA can be found in the viral genome.
Environmental elements known as mutagens are what trigger mutations. Radiation, chemicals, and pathogenic agents are examples of mutagens. Mutations may occur naturally spontaneously.
Because it generates a new DNA sequence for a particular gene, the mutation is crucial in the initial stage of evolution because it results in the creation of a new allele. Through intragenic recombination, recombination can also produce a new DNA sequence (a new allele) for a particular gene.

The long-necked giraffes can access more food, so they have a better chance of surviving to reproductive age.
