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 answer is; E
With environmental changes, the carrying capacity can either increase or decrease. It is important to note that the carrying capacity is the number of individuals of a species that a habitat can sustain indefinitely. With favorable environmental conditions, the carrying capacity increases while unfavorable environmental conditions decrease the carrying capacity.
Answer:
the candle will go out
Explanation:
since without oxygen it can't burn in a closed environment the oxygen will either be to low or not even present
Answer: Option B.
Biogeographical
Explanation:
Biogeographical evidence is the evidence that provide information of organisms distribution over geographical areas. It provide information on how and when the organisms evolved and common descent.
Frombthe question, biogeographical evidence will help Darwin make his observation
Answer is only 1st case that is homozygous zygote is the right answer.
Explanation:
In maternal recessive mutation both the alleles are mutant and exhibit mutant phenotype. The mutated alleles are present as homozygous.
From the definition it is concluded that:
first case, homozygous zygote is mutant phenotype
second case, heterozygous zygote not mutant phenotype
in third case, heterozygous zygote not mutant phenotype.
