Answer:
Polydactyly in the Amish population is an example of Founder effect
Explanation:
Founder effect is defined as loss of genetic variation as it occurs when a new population is formed by small number of individuals that are diverge from the a large population.
Polydactyly is an example of these founder effect that causes formation of extra finger which takes place when a a polydactyly man marry within their own community. As a result,genetic variation does't takes place among them and thus the offspring carry recessive genes which leads to this type of rare genetic disease.
In the lock and key model of enzyme action, the substrate fits into the active site of the enzyme, then after undergoing a conformational change, it will release the substrate and produce a product.
Multiple choices;
a.Twelve water (H2O) molecules were used to make it.
b.Twelve hydrogen (H2) molecules were used to make it.
c.Six oxygen (O2) molecules were used to make it.
d. Six carbon dioxide (CO2) molecules were used to make it.
Answer;
A.Twelve water (H2O) molecules were used to make it.
Explanation;
-The reactants that are required for the process of photosynthesis to take place are; carbon dioxide, water and light energy from the sun.
-The photosynthetic process utilizes 12 water molecules, six carbon dioxide molecules and light energy to produce one glucose molecule, six water molecules and six oxygen molecules.
This can be represented by the following chemical equation:
12H20 + 6CO2 + light energy = C6H12O6 + 6H2O + 6O2
Answer is outer core.
Reason - The outer core is the third layer of the Earth. It is the only liquid layer. The outer core is responsible for Earth's magnetic field.
