"When there are multiple mutations in a gene" is the one among the following choices given in the question that <span>is a mutated gene most likely to be passed along to offspring over several generations. The correct option among all the options that are given in the question is the second option or option "B".</span>
The answer is invasive species.
Invasive species are species that are not native to specific ecosystem,
but they have a capability to spread widely through the ecosystem, This way
they can threaten native species of the ecosystem or cause
environmental harm.
<span>After being introduced into the Black Sea, they greatly affect local
ecosystem. In the new area, they have no natural predators and are able to
spread. If they spread beyond the area they are introduced, they
become invasive species which can overgrow native biotopes and are
a great threat to the local biodiversity. This could lead to the extinction
of some native species.</span>
Answer: Adaptive immunity
Explanation:
The adaptive immunity is also known as acquired immunity. It is a sub system of the overall immunity.
It can defined as the immunity which is not present in the body when we are born. It develops in the body when it is exposed to the pathogens no matter it is natural or artificial.
The acquired immunity can develop in the body and makes the body susceptible to infections and develops prevention for the next time when the body will be exposed for the next time.
She was suggested to increase calcium phosphate and reduce soda content because acidic soda dissolves the calcium phosphate of the teeth.
Explanation:
Calcium phosphate is an important mineral which keeps the teeth firm and strong. If calcium phosphate is not present in adequate quantity it will cause the teeth to become soft and easy for cavities to get formed.
Calcium phosphate naturally repairs the teeth by remineralization process.
Soda contains phosphoric and citric acids which dissolve the protective layer of calcium phosphate of the teeth and makes it brittle causing increased cavities.
