Answer:
A mutation is a change in a DNA sequence. Mutations are commonly caused by mistakes during DNA replication. However, they can also be caused by ultraviolet radiation, exposure to chemicals called mutagens, and infection by viruses. But, a mutation usually occurs when a nucleotide in the DNA gets changed, causing the nucleotide sequence to be copied incorrectly which leads to the wrong code for a protein. This can sometimes be fatal.
Hope that helps.
True
Organisms depend on many nonliving things in their environment, such as air, food, water, etc. If something were to happen to an organism's nonliving environment (ie a drought, fire, water contamination), the organisms would be severely affected.
D, death & birth rates are at an equilibrium causing population to be constant
Answer:
The correct option is ALL THE REDWOOD TREES THAT LIVES IN A FOREST.
Explanation:
In the study of the ecosystem, population refers to a group of living organisms that belong to the same species and which live in the same area and interact with one another. In the options given, option A is wrong because a spider and a fly are not the same specie. Option C is wrong because all the plants that live near each other in a forest can not be the same species. Option D is wrong because all the coyotes on earth are not living in the same environment, where they can interact with one another. Option E is wrong because the earthworm that live in a grassland and the one that live in the forest are not living in the same environment and therefore can not interact.
The process that removes metabolic waste from an organism is called the excretory process. Through this process excretes are substances that are not used by the organism and thus must be excreted.
