An organism is d. a group of organ systems working together.
An atom goes into a molecule which goes into a cell which goes into a tissue which goes into an organ which goes into an organ system which goes into an organism.
Organs working together with other organs create a system of organs or an organ system. Something like this helps keep a human body, for example, functioning since everything relies on each other.
Remember that if your respiratory (breathing) system and nervous (brain) system did not work together, you would not be alive, and therefore no longer a living organism.
Answer:
A) Remaining populations will have reduced genetic diversity
Explanation:
A random mating population allows for genetic diversity as each individual have equal chance of been mated to and it allows for perpetuation of frequently occurring genes.
For a small population the frequency of allele is mostly fix with virtually all loci having the same genotype because mating is within small individual and genes whose frequency is few will be drifted out of the population.
Hence, after the eruption due to a small random population diversity will be reduced as diversity occur more in a large random mating population.
The organism that grows on the body of another organism and derives nutrients from it is known as a parasite. The organism that obtains nutrients from the dead or decaying organic matter is called saprotroph.
There are bacteria, like the Pseudomonas fluorescens and Marimonas protea, that can reside even in frozen surfaces. They do it by entering a dormant state where they wait patiently to be free from ice and grow again.
Bacterial adaptation to cold surroundings also involves changes in their membrane composition and translation and transcription machinery. This includes bacterial conjugation.
The answer is A.
I think it is A because they can just destroy it but D is finding something natural to kill it off but it is GM so it wouldn't help so A
