Answer:
See below
Explanation:
There are several reasons that genetic variation occurs. Some of them are as follows: mutation, random fertilization, recombination event during meiosis etc. The way in which this variation in genetics is distributed is in a continuous way. In case of the human species, it is reported that 85% of all variation is within a certain population, while the remaining 15% of genetic variation is between populations.
Your answer should be A. by observing the formation of sedimentary rocks.
Answer:
A. Biodiversity will decrease .
Explanation:
- The loss of a keystone species can cause extinction or mass destruction of other species that are dependent on it because keystone species are those species which significantly influence the existence and survival of other species in an ecosystem
- Since, beavers are considered as the keystone species, their removal from the ecosystem will cause loss of many other species in the ecosystem resulting in Decrease in the biodiversity of that ecosystem.
Estuaries are areas where fresh water from rivers meets salt water. As the river drains, it carries much nutrient-rich sediment. Many animal species depend on this food source to provide for their young.
<h3><u>Answer;</u></h3>
ATP and NADPH that were supplied through the light reactions
<h3><u>Explanation</u>;</h3>
- <em><u>Calvin cycle reaction is the portion of photosynthesis that takes place in the stroma of chloroplasts and can occur in the dark; it uses the products of the light reactions to reduce CO2 to a carbohydrate.</u></em>
- The Calvin cycle is divided into three portions: CO2 fixation, CO2 reduction, and regeneration of RuBP. Because five G3P are needed to re-form three RuBP, it takes three turns of the cycle to have a net gain of one G3P. Two G3P molecules are needed to form glucose.
