Answer: The correct answer is option a.
Explanation:
Prezygotic isolation is a mechanism by which mating and fertilization is prevented. Thus, it prevents the formation of a zygote.
It can be achieved by various reasons such as temporal differences (difference in mating seasons), habitat isolation, behavioural differences (different mating rituals such as different dance patterns, voice calls, et cetera), mechanical isolation, et cetera.
Thus, different breeding calls prevent the species to interbreed with each which ultimately prevent the formation of zygote formation.
Hence, it is a type of prezygotic isolation.
Answer:
C. Trees
Explanation:
Trees can be replanted and we can grow more, even though it takes a long time this still makes them a renewable source.
Dodder is a parasitic plant which has A. HAUSTORIAL ROOTS for support and absoption of nutrients from the host plant.
Dodder can not live alone. It grows from a seed and sprout from the ground but if it does not find a host within 10 days, it will die.
When the Dodder finds its host, it twines itself in a counter-clockwise direction around the stem of its host. The Dodder stem has bumps called "haustoria". These bumps are tightly pressed against the stem of the host plant and said bumps will eventually push their way inside the hosts' stem to pull the nutrients it needs to survive to the detriment of the host plant.
Dodder plant may be parasitic but it does not kill its own host instead it causes the growth of the host to be stunted.
