Answer: The correct answer is- bone structure of the baleen whale and the hummingbird share common ancestor.

Bone structure of the baleen whale and the hummingbird are the homologous organs.

Homologous organs can be described as the organs of different animals, which possess same basic structure but perform different functions.

For example- The flippers of a whale and forelimb of man, bone structure of the baleen whale and the hummingbird.

Baleen Whales and hummingbirds have a basic tetrapod skeletons, which is inherited from a common ancestor. But their bodies have been modified and they have lost parts through natural selection. This results in different adaptation in the form of their respective lifestyles over many years.

Explanation:

The pentose phosphate pathway is a two‑stage pathway that generates NADPH which is a reductant in many biosynthetic reactions and takes part in detoxifying reactive oxygen species, and ribose 5-phosphate which is a nucleotide (DNA and RNA) precursor.
The substrate for the pentose phosphate pathway is G6P.
Nonoxidative the is the phase of the pentose phosphate pathway interconverts phosphorylated monosaccharides, some of which can feed into the glycolytic pathway.

When a bacterial cell is present in an environment where both lactose and glucose are present, the glucose will be metabolized f

Umnica [9.8K]

Answer:

Option (A).

Explanation:

Lac operon system in bacteria explains the lactose metabolism in the cell. The first operon system was discovered by Jacob and Monod. Operon may be defined as the cluster of genes that are transcribed as a single RNA unit.

The bacteria uses glucose if glucose and lactose are present in the media. The bacterial cell can recognize the glucose presence as CAP-cAMP complex are required for the process of transcription and the complex level is low in the presence of glucose. This way bacteria turns off transcription for lactose genes even when the lactose is present.

Thus, the correct answer is option (A).

Answer:

The correct answer is option B, Encourage people in the neighborhood to use more disposable products.

Explanation:

The best way to reduce the waste is to stop its negative impact at the source of generation. In a neighbor hood, all the house can be considered as a source of waste generation. Thus if people are encouraged to use disposable product, it would be very easy to just collect and dump the waste without segregation. This will save time, money and effort.
