Answer:
The correct answer will be- light independent reaction or Calvin cycle
Explanation:
The process of photosynthesis takes place in the two phases: light-dependent and light-independent phase.
The light-dependent phase form NADPH and NADPH which are utilized during the light-independent phase to synthesise glucose molecule.
The light-independent phase occurs in the cytosol or stroma of the chloroplast in dark conditions which help synthesize the glucose molecules. The light-independent reaction is also known as the Calvin cycle which forms the glucose molecules in three steps- carboxylation, reduction and regeneration.
Thus, the Calvin cycle is the correct answer.
A Polypeptide chain is a sequence of amino acids that is the foundation for the basic structure of a protein
Answer:
1. Protect biodiversity
2. An indicator species
3. Biomagnification
4. Cutting down all the trees for lumber
5. Bioaccumulation
Explanation:
1. Conserving areas such as rain forests protect biodiversity because rain forests hold one of the highest biodiversity. They carry different types of resources that support different forms of life and at the same time, the organisms that live there support each other as well.
2. An indicator species is an organism that scientists can observe to see if there are changes in the environment it lives in. They judge the change or the implications based on the absence of the species in the environment (in which they used to be present), the presence of the species, and markers of adaptation due to the change in the ecosystem.
3. Biomagnification is a term used when contaminants that were consumed by the organisms in the lower trophic level are passed on to the next trophic level in higher concentrations. This is why those in the highest trophic levels are affected the most because they get the higher concentration of contaminants. DDT was banned when this phenomena was observed.
4. The greatest decrease in rain forest stability would be due to the cutting of trees. We can disrupt stability by gathering resources like nuts from some trees or when you remove one species of plant for medicine. However, the trees are an essential part of the rain forest because each part or area of the tree support different organisms. By cutting the whole trees off and several of them, you doom the organisms that rely on them as well.
5. As mentioned above, bioaccumulation is often interchanged with biomagnification but they differ in the usage of the terms. Like biomagnification, it talks about the accumulation of contaminants in organisms that ingest or absorb them. But bioaccumulation is a term used in a smaller scale, where it talks about the accumulation of the contimants in the tissues of the organism and not how they are passed on.
Excessive calorie intake during pregnancy can result in a fetus that has high birth weight. Pregnant women have indeed higher energy requirements but only by 300 calories daily. Eating an excessive amount of calories daily during pregnancy can lead to an increased weight gain that can result in an increased birth weight. Excessive weight gain during pregnancy can also endanger the progression of the pregnancy and the delivery of the baby.
Answer: Symptoms of potassium deficiency appear on the lower portion of the plant first with chlorosis (yellowing) at the leaf margins followed by necrosis (death). Potassium deficiency can be caused by soil pH, extreme liming or calcium rich areas of fields, lack of soil oxygen or true soil deficiency.
