B. Group number
For example, Sodium(Na) is in Group 1 and Na^+ has a charge of +1.
The correct answer is that variable number repeats are used in DNA tests; they have hundreds of possible lengths. Eye color is determined by variations in a person's genes. Most of the genes associated with eye color are involved in the production, transport, or storage of a pigment called, melanin. Eye color is directly related to the amount and quality of melanin in the front layers of the iris.
Answer:
A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass.
Explanation: A food web consists of all the food chains in a single ecosystem. Each living thing in an ecosystem is part of multiple food chains. Each food chain is one possible path that energy and nutrients may take as they move through the ecosystem.
Given what we know, we should observe the objects falling at the same speed in both the tower and vacuum scenarios, but not in the water.
<h3>What affects the speeds at which these objects fall?</h3>
- The falling speeds in both air and a vacuum will be the same for both objects.
- This is because falling speed is determined by gravity and is independent of the mass of the objects falling.
- The same will occur in water if and only if the densities of the two objects are equal.
Therefore, given that we can safely assume that the densities of the two objects are different from one another, we can confirm that while the objects will fall at the same speed in air and in a vacuum, this will not be the case in the deep pool.
