genetic drift
Explanation:
Genetic drift is changes in allele frequencies of a gene pool due to chance or random events. This can occur in large or small populations. Genetic drift causes gene pools of two isolated populations to become dissimilar as some alleles are lost and other are fixed.
Answer:
Embryo
Explanation:
An embryo refers to the early stage of development of a multi-cellular organism and it occurs just immediately after fertilization. This development often continues through the formation of cell, tissues, organs.

These starting substances of a chemical reaction are called the reactants, and the new substances that result are called the products.
Answer:
Because of the fact that Snails cannot survive in nasty water.
Explanation:
<h3><u>Answer;</u></h3>
<em>ATP and NADPH</em>
<h3><u>Explanation;</u></h3>
Three-carbon molecules of PGA are converted to G3P small sugar molecules by <em><u>ATP and NADPH</u></em>, which come from the light reaction.
- <em><u>Photosynthesis</u></em>, a process in which green plants use energy from the sun to make their own food, involves two types of reactions, light reactions in light stage and light independent reactions in dark stage.
- During <em><u>the light reactions ATP and NADH are generated from the electron transport chains</u></em>, which are then taken to the second stage (light independent stage) of photosynthesis. During the Light independent stage the energy stored in ATP and NADH is <em><u>used to convert 3-carbon PGA to G3P</u></em>.
