The correct answer is: B) H2O
Non-cyclic photophosphorylation is a light reaction and it occurs in the thylakoid membrane and it involves two different chlorophyll photosystem.
Non-cyclic photophosphorylation is a reaction where a water molecule is broken down into 2H+ + 1/2 O2 + 2e− . This process is called photolysis. The 2H+ and 1/2O2 from the water are left out for further use, while two electrons are kept in photosystem II.
Answer:
With the invention of the PCR technique , DNA profiling took huge strides forward in both discriminating power and the ability to recover information from very small or degraded starting samples.
The process of PCR mimics the biological process of DNA replication but confines it to specific DNA sequences of interest.
In PCR process , the DNA sample is denatured into separate individual polynucleotide strands through heating. Two oligonucleotide DNA primers are used to hybridise to two corresponding nearby sites on opposite DNA strands. Thus two new copies of the sequences of interest are generated.
Repeated denaturation , hybridisation and extension in this fashion produce an exponentially growing number of copies of the DNA of interest.
Quantitative PCR methods enable automated , precise and high - throughput measurements.
Answer:
A substance that removes carbon dioxide gas
Explanation:
Options-
A. A substance that removes carbon dioxide gas
B. A plant to produce oxygen
C. A glucose reserve
D. A valve to release excess water
Solution -
It is given that the rate at which oxygen is consumed and the rate at which carbon dioxide is produced is same. Therefore, if we somehow are able to measure the volume of carbon dioxide, we can interpolate the rate of consumption of oxygen from it.
Hence, A substance that removes carbon dioxide gas is essential to provide accurate volumetric measurements of oxygen gas consumption
Option A is correct
<span>Answer:The blood vessels in the brain are blocked.

Vascular neurocognitive disorder
is a condition caused by reduction or blockage of the brain’s blood supply. Because of the lack of blood, a certain region of the brain was damaged, changing a person’s
brain functions.
When an automotive battery is fully charged, the sulfuric
acid and water mixture will have a specific gravity of about 1.3. Specific
gravity is actually the difference in the weight of water in comparison to a specific
fluid. It is measured by a hydrometer. The amount of charge in the battery is
normally measured by the specific gravity of the battery. The specific gravity
of water is 1 and anything less than one is considered less dense while
anything that has a specific gravity of more than 1 is considered more dense
than water.
