A small island is home to a unique population of land snails. This population was founded by 10 individuals that floated to the
vekshin1

Answer:

  • The Island population likely has fewer alleles-that is versions of genes-than the mainland population.

       A- Agree <u>B- Disagree</u>

  • Genetic drift is more pronounced in the island population than in the mainland population in these first few generations

       A- Agree <u>B- Disagree</u>

  • Some harmful traits may have become more common in the island population than in the mainland population

       <u>A- Agree</u>- B- Disagree

  • Biologist observed genetic drift but not evolution

       <u>A- Agree</u> B- Disagree

Explanation:

If there was genetic drift, then allele frequency either increased or decreased by chance, irrespective of natural selection that is irrespective to weather those alleles helped individuals survive in the island environment. In molecular genetic data, there are statistical signature in the  population variation that indicate weather selection or other processes occurred.

Which of the following factors is needed during light-dependent reactions to create ATP and NADPH energy molecules?
Alexeev081 [22]

Answer: The correct answer is- Solar energy, carbon dioxide, and water.

Light dependent reactions comprise the first phase of photosynthesis (formation of food by green plants and algae in presence of sunlight) process.

This phase occurs in the thylakoid membrane of chloroplast.

During this phase, a green pigment chlorophyll absorbs energy from sunlight (in the presence of carbon dioxide and water) and convert it into chemical energy in the form of ATP and NADPH.

This energy is further utilized in the formation of food (glucose) in the next phase, which is a light independent phase of photosynthesis.

In photosynthesis, oxygen is produced by splitting of water molecule and it is released in the atmosphere.

Thus, solar energy, carbon dioxide, and water is the right answer.

How is a trait passed down from parents to offspring USE OWN WORDS
artcher [175]
A trait is a characteristic, such as color or size, that is inherited by an offspring from its parents. The genes that control a trait come in pairs, one gene from each parent. We represent these gene pairs by writing a combination of two letters. For example, if one parent contributes a gene for blue eyes (c), and other parent contributes a gene for brown eyes(C), then we write the offspring’s eye color trait as Cc. This combination, of the two genes that determine the trait, is called a genotype. If gene pair contains a dominant allele, the the offspring will show this dominant trait
