I believe
this is a true statement
- keystone species is the correct answer.
<u>keystone species</u> which keeps the number of other animal population in
control and low in the entire ecosystem. They play an important role
through this process and helps the food chain effectively.
dominant species - most common species; found often in the ecosystem.
invasive species - which fights for itself survival and can cause harm to
ecosystem. non-native to an ecosystem
Answer:
The most recent common ancestor of all currently living organisms is the last universal ancestor, which lived about 3.9 billion years ago. ... 6,331 groups of genes common to all living animals have been identified; these may have arisen from a single common ancestor that lived 650 million years ago in the Precambrian.

Definition:
Autosomal Dominant Disorder:
A disorder in which could pass a disease from generations and on. In other words, future generations "inherit" the disease
____________________________________________________
Explanation:
The reason why "autosomal dominant disorder" is the correct answer because when a disease has been going on for many generations, this would be known as an autosomal dominant disorder, or ADD. What this means is that a person could have a mutant gene in them, also having a normal gene that is paired with autosomal chromosomes. These diseases are inherited from a off spring that could take the disease and pass it on to their off springs, which would go on for generations due to the fact that it is a "dominant" trait. This is similar to the autosomal recessive disorder, but the autosomal recessive disorder needs two mutant genes in them, meaning that there is a less likely chance of getting the disease passed on to the off spring. The autosomal dominant disorder only needs one mutant gene in order to be effective during the inheritance for a offspring.
