A)animal cells must be in osmotic equilibrium with their surrounding environments, because if they swell or shrink their membranes will rupture.
Answer: Natural selection is selection due to environmental conditions from random genetic mutations in a population. Among the variants in a population, some will be slightly better adapted to conditions and will eventually out-compete the rest of the population. Survival of the fittest actually means survival of the best adapted, or fittest for purpose, i.e. to survive and thrive.
Explanation: This phrase has caused much miunderstanding of the evolutionary process. ‘Fittest’ has been equated with biggest, or strongest or fastest, but this was a description originating in the nineteenth century, when it was understood quite differently.
Natural selection arises from genetic variation in a population. Jaques Monod, an esteemed scientist, described evolution as where chance and opportunity meet. Chance lies in the genome of a species, random mutations, and the resulting genetic variation in the population.
Opportunity lies in the environment. Environmental change creates opportunities for some, extinction for others. Opportunities can also be from exploiting new environmental niches.
Natural selection is the process by which some random genetic variation gives some of a population a competitive advantage. competition eventually results in one population out-competing all others in its niche. The end-result of competition in nature is monopoly.
But this process continues and further random mutations can result in another population becoming better adapted. That is the actual meaning of survival of the fittest: in modern terms we might say ‘fittest for purpose’, that is, the species orvpopulation best adapted to survive and thrive in that environment.
Answer:
Alright...
Explanation:
In a perfect world, I would split the land 50/50. Natural resources are important, and yes, if we would like a future on this planet, we should strive to find alternatives, but in the meantime, splitting it is the smartest thing to do. I would also suggest to make it mandatory to replant all the trees lost in a connecting area if possible.

The right approaches to population monitoring methods of swallows and tortoises are point counts and line-transect distance sampling, respectively.
- For point counts, In order to collect the data required to meet the current study's objectives, one must use field techniques methods for selection, counting, capturing, observing, measuring, and marking individuals chosen from the targeted population.
- To count or keep track of the birds of the air, point counts are a frequent field technique (birds).
- The practice involves making observations over a predetermined, set amount of time and keeping track of the number of birds coming from a specific location.
- While the line-transect distance sampling methods in the field are useful for keeping track of the number of tortoises and is appropriate for controlling and tracking the population.
