Answer:
The correct answer is "a hypertonic solution".
Explanation:
Seawater is the most clear example of a hypertonic solution in nature. The concentration of ions in seawater are far more superior than the concentration of ions inside a plant or an animal cell, since seawater have an osmolarity of about 1000 mOsm/l. Therefore, at high tide a plant or animal cell will be in a hypertonic solution, and the cells must have adaptions to avoid cell shrinking and dead.
Answer:
Scientific theories can never be proven true beyond all doubt; they can only be supported by a wide body of evidence. Only one of the statements that follow uses the term theory in its correct, scientific sense.
Explanation:
Humans, like all mammals, are diploid organisms. This means that we have two copies of each chromosome. In diploid organisms, one somatic cell would have two copies of each gene. This means that in one somatic cell, an individual carries two copies of alleles for long eyelashes, and also two copies of alleles for short eyelashes.
Answer:
Yes
Explanation:
Indeed, <u>the best solution for maintaining biodiversity is to conserve the biodiversity of every ecosystem, since all ecosystems have benefits to humans and the earth</u>.
Ecosystems might vary in the kind of services they render to the planet or humans in general. For example, the forest ecosystems supply humans with the necessary timber and wood for construction purposes and sequestrate carbon/produce oxygen from and to the environment respectively. Thus, the forest ecosystem plays a huge role in maintaining the air quality of the planet in addition to several other services.
The variation in the services the different ecosystems render to the human population and the planet necessitates that the biodiversity of every one of them be conserved. Prioritizing the conservation of one over the other will result in losing some of the services provided as a result of loss of biodiversity.
