Answer: The correct answer is- A.The plant might have a gene that is similar to a human gene.
Probe can be described as the segment of DNA or RNA (generally 100-1000bp in length) that is designed and radioactively labelled to detect the presence of nucleotide sequences, which are complementary to it.
In this question, the probe is synthesised using sample of human DNA but it also hybridizes with the plant DNA.
This indicates that plant genome has certain DNA sequence or gene that is similar to the gene in the human DNA.
Thus, option A) is the right answer.
Answer:
option B) intracellular receptors are present only in target cells.
Explanation:
The cell membrane or plasma membrane is composed of phospholipids and thus hydrophobic in nature, this allows the lipid soluble signaling molecules to cross the membrane. The cell membrane of all cells consist of phospholipids thus hydrophobicity of each cell membrane allows lipid soluble signaling molecules to pass through the plasma membrane. The testosterone cross the membranes of all cells but affect only target cells because of intracellular recepters that are located in target cell. The binding of signaling molecules to recepter generates a response. Thus, option B is correct.
Mimicry can be an essential part of survival for animals. For instance, it is common for offspring to mimic their mother in ways that are outside their genetic makeup, which can keep them safe from harm.
Explanation:
Sea surface temperature provides fundamental information on the global climate system. ... SST is an essential parameter in weather prediction and atmospheric model simulations, and is also important for the study of marine ecosystems. SST data are especially useful for identifying the onset of El Niño and La Niña cycles
