Answer:
Chromosomes are arranged in pairs because one of each set of the two comes from each parent .We receive half our DNA from our mother (in the ovum) and the other half from our father (in the sperm). A normal human being will therefore have 46 chromosomes or 23 pairs. This is mainly done to achieve genetic variation.

Answer:
As bicarbonate ions present in blood plasma
Explanation:
Most carbon dioxide produced by tissues (approximately 75%) is transported in the blood to the lungs as bicarbonate ions (HCO₃⁻).
<u>The chemical equilibrium is:</u>
<h3>CO₂ + H₂O ↔ H₂CO₃ ↔ H⁺ + HCO₃⁻</h3>
carbonic acid
In the lungs, the conversion is reversed, so CO₂ diffuses from the blood into the alveoli and then it's exhaled.
Although most CO₂ is reversibly converted to bicarbonte, approximately 5% is simply dissolved in the blood plasma and about 20% is bound with hemoglobin.
This conversion to bicarbonate ions keeps the partial pressure of CO₂ in blood plasma low, facilitating its diffusion away from the tissues.
Answer:
D. The native snail species will compete for resources with the invasive species and destabilize the ecosystem
Explanation:
In Ecology, an invasive species refers to a species of organism that is foreign i.e. non-native to a particular habitat or environment. They are characterized by the ability to proliferate in growth and compete for space and nutrients with the native species in the habitat they are introduced to.
In this case, the giant african land snail, which is an invasive species, if introduced into a stable ecosystem will compete for resources with the native species of that ecosystem leading to the destabilization of the ecosystem.
