Answer:
The correct answer will be- will be called "Clones" with no genetic variation thus result in less adaptability to environment.
Explanation:
Plants can reproduce by both modes of reproduction called asexual and sexual reproduction. The asexual mode of reproduction produces genetically similar offsprings in less period of time and thus helps in spreading of the species in minimum time as in the case of Kalanchoe.
The Kalanchoe can dominate a large area of the habitat using this mode of reproduction but at the cost of genetic variation.
Since asexual reproduction results in Clones with same genetic material so the descendants of the plant will be less adaptive to changing the environment as asexual reproduction does not involve genes.
Answer:
The correct answer will be option-E
Explanation:
Hershey and Chase's experiment was performed to test whether DNA serves as the genetic material or protein.
To perform experiment they grew bacteriophage into radiolabeled phosphorus and sulfur compounds. The phosphorus is an integral part of the structure of DNA whereas proteins contain sulfur in their structure.
In the given condition if radiolabeled nitrogen is utilized then the experiment will fail as the structure of proteins also contains an amino group( NH₂) in their structure as well as DNA. The scientist will not be able to identify whether the DNA is the genetic material or protein.
Thus, option-E is the correct answer.
Egg proteins are necessary for an embryonic development
Protein building begins with the DNA strand in the Ribosome. The DNA strand is essential to dictating the type of protein that is to be produced, based on the sequence of nucleic acids.
The correct answer is: 'Reptiles are ectotherms and cannot raise their body temperature above that of the environment'. Birds sit on their eggs to incubate the eggs as the body temperature of the adult bird warms up the eggs. Birds are <span>endothermic homeotherms, and maintain a constant body temperature. In contrast </span>reptiles <span>are ectothermic poikilotherms, and their body temperature depends on the temperature of the outside environment.</span>
