Answer:
Different species within a phylum all have the same basic characters, anatomical and functional integrity, common ancestry.
Explanation:
The animals having same phylum but different species have similar basic structural pattern. That means the anatomical features are constructed on the same ground plan. This individuals have similar functional integration. All animals of a phylum work as a functional machines with similar functional integration.
Another important feature is they have common ancestry. Evolutionary study have confirmed all members of a similar phylum have been derived directly or indirectly from a common primitive ancestry.
Answer:
Option C, Each subpopulation is linked to all other subpopulations by dispersal.
Explanation:
Each sub-population with in a metapopulation is not only connected by the dispersal distance travelled by an organism but also by the distance between the patches on which two sub population live. There are several other factors that limitise the concept of connection of subpopulation by dispersal factor and these vulnerable factors are – properties of terrain between the patches and its adverse affect on the dispersal behaviour of dispersing agent/species.
Hence, option C is correct.
so first of all the word abiotic means non living and the word biotic means living
so an example is that say a rabbit has just drowned in a pond the water is no longer able to be drunken by other animals or else they might be affected by it or what ever the bunny happened
Answer:
The activity of cyclic AMP phosphodiesterase is prevented by caffeine. The caffeine prevents further dissociation of cAMP, which eventually increases the response within the body. The activity of neurotransmitters, that is, of noradrenaline or epinephrine, gets increased due to enhancement in response.
This further enhances the activity of the heart, the rate of muscle contractions, blood pressure that further helps in delivering more oxygen to the brain, and other parts of the body. Thus, the inhibition of the enzyme cyclic AMP phosphodiesterase helps the athletes to prevent the wall.
