Answer: Radiometric dating

Explanation: Radiometric dating is a procedure used to determine the age of elements such as rocks and fossils. It is based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates.

A population of Anolis lizards lives on the mainland. During a storm, three groups of Anolis migrate to three islands, one large
natka813 [3]

Answer:

(i) Small island

(ii) Large island

(iii) Option-3

Explanation:

In the given question, the three population of the Anoles Lizards migrated to three islands of different size.

(i) Genetic drift is a random or by the chance process which changes the frequency of the alleles in the population. The change in the frequency of the allele can be easily observed in the small population therefore the small island with the smallest size of the population will have the strongest genetic drift.

(ii) Heterozygosity of alleles that is with a dominant and a recessive allele is the result of the exchange of alleles in the population. The size of the population is finite on the island therefore the heterozygosity is not introduced in the small population but in a large population, it can be introduced as the mating is random.

(iii) The genetic drift is strongest on the small island therefore L2 allele can be easily influenced by this effect. The selection coefficient is very small that is 0.002 therefore no mutation is occurring on the island.

Lipids commonly contain fatty acids. What are the two parts of a fatty acid? Check the correct answers below.
ch4aika [34]

Answer:

Hydrophillic head and a hydrophobic tail

Explanation:

Every fatty acid is composed of long chain of hydrocarbon tail. This hydrocarbon tail is nonpolar and insoluble in water. Hence this tail is labeled 'hydrophobic'.

However, the head of the fatty acid contains polar COOH group which is capable of interacting with water, hence the head is hydrophillic.

Hence, a fatty acid is composed of a hydrophillic head and a hydrophobic tail.
