Answer: The plant needs a pollinator as it does not pollinates itself.
Explanation:
The plant that was found in the rain forest grow there because of the climatic conditions. There was adequate amount of rain fall and optimum temperature in the forest.
It was pollinated by the insects as rain forest has different types of organisms living in there.
When that was grown in greenhouse effect there was no growth of fruits in the plant because there was no pollinator in the green house chamber.
The spider has a venom in their teeth that they inject into your skin when they bite you so you won’t bleed everywhere and your skin has a reaction to the venom because it’s strong enough to have an effect just not strong enough to hurt you.
Answer: option D) II, III, and IV only
II. Mutations can have a positive effect on an individual.
III. Mutations can have no effect on an individual.
IV. Mutations usually have a negative effect on an individual.
Explanation:
The effects of mutation on the fitness of an organism include:
II) a mutation can be positive once it increases the fitness of the organism e.g the emergence of the malaria-resistant sickle cell hemoglobin gene (AS) instead of the AA gene that is susceptible to malaria attack.
III) a mutation that occurs in an amino acid that results in the use of a different, but chemically similar amino acid e.g a change from AAA to AGA will encode arginine, a chemically similar molecule to the intended lysine. This is called a NEUTRAL MUTATION - and it has no effect on the organism
IV) In general, mutations usually are deleterious - having negative effects - and reducing the fitness of organism. e.g Sickle cell anemia and hemophilia are due to mutations
