Explanation:

To prove the necessity of carbon dioxide in photosynthesis following steps need to do

Insert a part of the leaf of a destarched plant into a conical flask containing potassium hydroxide.

Potassium hydroxide solution absorbs the carbon dioxide gas from the air present in the glass bottle.

Leave the plant sunlight.

After few hours, perform a starch test to this and another leaf of the same plant.

Observation-

Leaf exposed to the atmosphere are bluish black.

Leaf exposed to KOH does not change to blue-black colour

Result- Starch is present in the green part of the leaf.

Conclusion- Presence of starch proves that chlorophyll is necessary for photosynthesis as it traps sunlight.

Inbreeding will increase the relatedness between individuals in a population. Interbreeding refers to reproduction with another species (or race), and is often used as synonym to crossbreeding or hybridization (when referring to hybrid offspring from two different species/races/breeds, not DNA hybridization).

Which compound is the strongest acid? H2S HBr Li2O LiBr

Lunna [17]

Answer:

HBr

Explanation:

As per the given options, HBr could be considered the strongest acid and the strength of its bond that makes it the strongest acid. This acid is highly precarious and toxic in comparison to other acids. It is so strong that it can immediately disunite and concedes its protons in suspension later. It is also strong as it gets ionized completely in an aqueous solution and also due to the hydronium ions formation on suspension. The other compounds do not do so.

True or false: In order to increase the speed of replication, the DNA molecule is opened at several locations creating multiple

Romashka-Z-Leto [24]

Answer:

True.

Explanation:

DNA's replication is the process where each daughter cell receives the same copy of the DNA. During the synthesis phase of the cell cycle replication of DNA occurs. While increasing speed of replication the DNA molecule is opened at several locations, and creating multiple replication bubbles.

Replication bubbles opened DNA strands at several locations where DNA are complementary to each other, such as one strand of DNA contains a nucleotides sequence of TCAGTA will have a complementary another strand with the sequence AGTCAT.
