!.) Biodiversity is the variation of a species throughout an ecosystem
2.) Biodiversity forms the foundation of the vast array of ecosystem services that critically contribute to human well-being. and3.) <span>the variability among living organisms from all sources including, inter alia, terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are a part; this includes diversity within species, between species and of ecosystems.

Answer:
B - invasive species
Explanation:
Invasive species are species that are not native to a particular habitat but are introduced into that habitat intentionally or by accident.
The Burmese python was released in Florida (where it is not a native species). Because it is not from Florida, it does not have any natural predators there, and it can seriously damage the ecosystems by preying on organisms that have no adaptations against the new predator.
In case of severe burn injuries, a person experiences a sudden increase in the number of dangerous bacteria in the gastrointestinal tract approximately 32%. The increase in the dangerous bacteria increase the chance of developing gastrointestinal conditions like irritable bowel disease, and other non-related conditions like rheumatoid arthritis and diabetes.
But in case of less severe burn injuries, the dangerous bacteria accounted for just 0.5% of the bacteria. An imbalance in the bacteria cause long term health consequences, in fact some of the complications could possibly even result in death of a person with severe burn injuries.
Answer:
a. Heterozygous individuals may pass on their copy of the disease-causing allele to offspring.
Explanation:
Tay-Sachs, which is a recessive lethal disease ---- Let say the recessive lethal diseases is s
∴ it only results when an individual posses two copies of the diseases-causing allele i.e two copies of the disease will be ss.
Now, when two hetrozygous individuals crossed , it is obvious that each can pass on their copy of the disease-causing allele to the offspring.
Let show an illustration for the above statement.
Let the heterozygous individual be Ts, if Ts cross with another Ts;
we will have:
Ts × Ts
T s
T TT Ts
s Ts ss
the offspring are TT,Ts,Ts,ss
We can now see how the Heterozygous individuals pass on their copy of the disease-causing allele to the offspring (Ts).
