Answer:

  • Land animals require more energy since they have to overcome greater inertia during locomotion. Land mammals have adopted many evolutionary mechanisms to support high energy demand.
  • Heart is four chambered instead of the usual two in aquatic animals like fishes. More number of divisions in heart increases the efficiency of blood circulation process which in turn increases the oxygen delivery rate to cells for producing more energy.
  • Land mammals also have developed lungs which increase the efficiency of gas exchange process which increases the output of respiration process.
  • In addition, land mammals also have a strong and developed musculoskeletal system which helps in locomotion.

Explanation:

The locomotion on land requires more energy than the locomotion in water which can be observed in the land animals like mammals.

In mammals, to move on the land, there should be a well-developed organ which could help in the circulation of blood to all the tissues and the mammals developed the well developed the four-chambered heart which required energy to pump the blood.

The mammals evolved the well-developed lungs to exchange the gases with the environment.

The trp and lac operons are regulated in various ways. How do bacteria regulate transcription of these operons? Sort the stateme
OLEGan [10]

Answer:

Operon is not transcribed:

-lac operon: lactose absent

-trp operon: tryptophan present

Operon is transcribed, but not sped up through positive control:

-lac operon: lactose and glucose present

-trp operon: tryptophan absent

Operon is transcribed quickly through positive control:

-lac operon: lactose present, glucose not

Explanation:

The trp operon is controlled via negative control only.

Presence of tryptophan will inhibit the transcription of the operon genes

The lac operon is controlled via negative control and positive control.

●Negative control:

--Transcription is turned off due to

active Repressor protein and absence of lactose

--Transcription is turned on due to

Inactive Repressor protein and presence of lactose

●Positive control:

--Transcription rate is higher due to absence of transcription and presence of lactose as a regulatory protein (CAP) adhere to the lac operon promoter

A mutation that results in a single amino acid substitution in Ras abolishes its ability to hydrolyze GTP, even when GTPase-acti
Drupady [299]

Answer:

The new drug will not be effective against the treatment of cancer.

Explanation:

The drug will not be effective against the cancer treatment because the drug will inhibit the dimerization of receptor tyrosine kinase (RTK) but as the Ras has undergone mutation due to replacement of one amino acid, it will be constitutively expressed and the drug is not effective in stopping the Ras functioning.

Thus, Gefitinib cannot work against the cancerous cell as it is not potent to stop the functioning of mutant Ras protein.
