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.
The parietal lobe contains the primary sensory cortex, which controls sensations such as touch or pressure.
Answer:
innate immunity : highly specialized defenses.
Explanation:
Immunity against infectious diseases are 2 types - innate immunity and acquired immunity. Innate immunity is the type of defense mechanism which is present at birth. This type of immunity does not depend upon the immunization. This type of immunity is not highly specific as acquired immunity. Innate immunity has no memory and response in first-rate towards the antigens. The phagocytic cells, dendritic cells are some cells of the innate immune system. This changes throughout the lifetime. Different species have different innate immunity. It means different species show different susceptibility to different diseases. e.g Rats are unsusceptible to Diphtheria while men, guinea pigs are highly susceptible to Diptheria.
Pyridostigmine is a acetylcholinesterase inhibitor which acts as a cholinergic drug. Acetylcholinesterase or AChE is the enzyme that breaks down the major neurotransmitter acetylcholine into acetyl-CoA and choline, rendering the neurotransmitter useless. In a patient that had major adverse effects upon administration of pyridostigmine, the correct drug to be given as antidote for a cholinergic drug is an anticholinergic drug such as atropine.
