Answer:
The proper matching is given below.
Explanation:
Predation Typical plant defence include(thorns,sticky substances) and chemicals(toxin,bad tastingchemicals) adaptation.
Competition When individuals fight for a common resource,the weaker one experience loss or affected adversely.
Disease pathogens can be transmitted to host by direct contact between hosts o through soil,water,air or any other surface.
Symbiosis This interaction is of three types : mutalism,Commensalism and parasitism.
Answer:
The correct Answer is A.
Explanation:
The Flow chart of the Carbon Cycle, will look as follows:
1. Carbon dioxide in the atmosphere.
2. Producers undergo photosynthesis (in this process plants among other producers like algae, use CO2 to produce energy).
3. Consumers eat producers (a primary level of consumer like a rabbit eats the producers or plants).
4. Decomposers return Carbon to the soil and release waste.
And the cycle continues again, by going back to step 1.
D) areas at high latitudes
Answer:
The correct option is C. Rare alleles tend to remain rare even when they are dominant.The distribution of a gene among individuals is determined by mating and environmental factors.
Explanation:
Most people believe that a rare allele would only be recessive. But this is not correct. A rare allele can be dominant. The frequency of an allele to occur in a population will depend on the environmental factors. The alleles which code for traits that are best suitable for living in an environment will be seen in more abundance. The frequency of an allele to occur in a population also depends on the breeding trends of the population.
