What is water’s role in the light reaction of photosynthesis?

Biology

The correct answer is - Its electrons are used to form NADPH.

On receiving light energy, electrons are expelled from the reaction center of photosystem II. The expelled electrons finally reduces oxidized NADH⁺ to NADH. The oxidized reaction center of photosystem II split water into protons, electrons and oxygen. The electrons released from water reduces oxidized reaction center of photosystem II. Thus, oxidized reaction center of photosystem II gets back its expelled electrons. Therefore, electrons from water forms NADH.

The correct answer is option A, Its electrons are used to form glucose.

Reason -

In the light reaction phase of photosynthesis, the water gets broken into its constituent’s elements that are oxygen, H+ ions and free electrons. This process takes place in the thylakoid membrane in the presence of an enzyme. The released free electrons replace the loss of electron during the process light dependent reaction in the photosystem II.

Answer:

a. Mammalia

Explanation:

Mammalia are the class species that have distinct systems and separate ducts for different activities like reproduction, excretory, and defecatory and moreover they have nipples to feed their young ones.

So, the above species which has a single duct for reproductive, excretory, and defecatory material as well as a lack of true nipples does not belong to Mammalia

Umami taste receptors are capable of detecting _________ ______ in acidic foods and substances.
yarga [219]

Answer:

Amino acids and glutamates

Explanation:

Umami taste receptors or savory taste receptor is the fifth basic taste receptor derived its name from the Japanese name for the fifth basic taste  (which includes bitter, sweet, salty and sour tastes).

Umami is savory taste which includes the features of cooked meat as well as broth.

Umami taste receptors detects glutamates present in fermented food and meat broth. These receptors are also capable of detecting monosodium glutamate, GMP and IMP in meats, cheese, etc.

Explanation:

Meiosis makes genetic variety possible. It makes sperm & egg cells called gametes. Each gamete has 23 chromosomes. To make a diploid cell two gametes (sperm & cell) come together.

During prophase 1 the chromosomes pair up with their homologous pairs so they can transfer their genetic information and exchange it between each other. It makes recombinant chromosomes that influence the genetic diversity between the same people.

Now they are in metaphase 1, the chromosomes are in pairs in the middle of the cell. In anaphase 1, the chromosomes are pulled away by the spindle fibers. Then in telophase 1, there are two formed nuclei. Cytokinesis 1 then splits the cytoplasm.

Now they are in meiosis 2. During prophase 2, there are chromosomes and the spindles are starting to form again without crossing over like in prophase 1. In metaphase 2, chromosomes are going to line up in the middle in both cells unlike during metaphase 1 where the chromosomes were only in pairs.  In anaphase 2, only the chromatids are being pulled away by the spindle fibers. Next in telophase 2 the nuclei reform and the 2 cells are each going to divide into 4 cells. Finally, cytokinesis completely splits the cytoplasm.

Keeping in mind that each sex only produces one type of gamete cell (sperm or eggs), and of the independent assortment and crossing over of chromosomes, the end result will be diversity.

Which describes a climate effect on the rate of weathering?
tester [92]

Answer:

Cold climates favor mechanical weathering.

Explanation:

A cold, dry climate will produce the lowest rate of weathering. A warm, wet climate will produce the highest rate of weathering. The warmer a climate is, the more types of vegetation it will have and the greater the rate of biological weathering
