Rabbits can breed for the first time at the age of three months. They have a gestation period of about 31 days, and there can be anywhere from four to 12 young in each litter. What would be the most likely long-term consequence if a breeding pair of rabbits was released into an ecosystem with no predators large enough to eat a rabbit?
Answer:
They would most likely overpopulate. That sounds like a good thing, but if that happens they would exhaust their food supply way to quickly and they would starve to death. This is why they need a predator, to balance the ecosystem.....The rabbit population would grow quickly until all the edible vegetation was gone and then the rabbit population would crash.
Explanation:
Answer:
The rabbit population would grow quickly until all the edible vegetation was gone and then the rabbit population would crash

C) Nitrogen and an R-group are present in proteins and nucleic acids
D) Hydrogen , carbon and oxygen atoms are present
D) Hydrogen , carbon and oxygen atoms are present
The statement that best describes the macromolecules is Hydrogen , carbon and oxygen atoms are present. Thus, option D is correct.
What is Carbohydrates?
Carbohydrates is defied as that contains biomolecule that contains carbon hydrogen and oxygen in a ratio of 2:1. Carbohydrates are mane source of energy of the body they work as fuel for the brain, kidneys central nervous system and heart muscle.
[tex]Cn(H2O)n[/tex] is the basic formula for all carbohydrates . But this formula have limitation i.e it applies where same amount of carbon and water are use. Initially the terms carbohydrate was used to describe compounds that have really contains carbohydrates. Because they had simple formula [tex]CH20.[/tex]
In modern Era carbohydrates are classified on the basis of their structure not on their formulae. Such as aldehydes and ketones are now known as polyhydroxy. Carbohydrates provides glucose to the body and, thereby, long lasting energy.
Therefore,The statement that best describes the macromolecules is Hydrogen , carbon and oxygen atoms are present. Thus, option D is correct.

What are phytoplankton?These are marine algae which are photosynthetic.
They provide food for a diverse range of sea creatures in a healthy ecosystem.
Phytoplankton, also known as microalgae, are algae that, like terrestrial plants, contain chlorophyll and require sunlight to live and grow.
Thus, it can be concluded that nearly 50-80% of oxygen develops through photosynthesis from oceans exhibited by phytoplankton, drifting plants, etc.
