Answer:
(B) Lava has separated the population into two areas: an upland forest and a lowland marsh.
Explanation:
In allopatric speciation, individuals of an ancestral species may undergo evolution into two or more progeny species which arises when physical separation causes a geographic boundary, this barrier can be in the form of a mountain range, rockslide, river or lava.
As in this scenario, a lava flow divides the populations of annual herbaceous plants by altering the landscape. This will cause genetic divergence with varying heritable features among its many generations favouring different traits in the separate environment along with genetic drift. The Lava will separates the population into two areas: an upland forest and a lowland marsh.
Antihistamines are drugs that are used to treat allergic rhinitis (both seasonal and perennial) and other form of allergies that cause hives or urticaria. They can give relief when a patient has nasal congestion, sneezing or hives because of pollen, dust, or animal allergy (allergens). Second generation antihistamines such as loratidine are prescribed for seasonal allergies because they are less sedating than the first generation antihistamines.
The National Academy of Sciences has established the Acceptable Macronutrient Distribution Range (AMDR), which are dietary guidelines regarding the acceptable range of certain nutrients (such as fat, carbohydrates and protein) in our everyday diet. According to the AMDR, 45-65% of our everyday calorie intake should come from carbohydrates. Therefore, 1125 [(2500*45)/100] to 1625 [(2500*65)/100] kilocalories should come from carbohydrates.
There are many steps in designing and conducting a scientific experiment, but the main ones are a hypothesis, trials, step/procedures, and a conclusion/review
