They are usually small because they need to transport nutrients across the membrane. Only particular amount can cross per/area. As the volume of cell increases, it increases in geomatrically faster than the area of the membrane.It becomes difficult to a certain point to supply the given volume with enough membrane to allow the gases/other molecules to transport across the membrane

all plants give out oxygen during day and carbon dioxide during 9 to you agree with this statement give reason

ankoles [38]

Answer:

Yes, I agree with the given statement.

Explanation:

Plants undergo the process of photosynthesis for the production of their food. In this process, they require the presence of sunlight, carbon dioxide, water, minerals, and chlorophyll. The process of photosynthesis is possible only during the day because sunlight is one of the major components. Carbon dioxide is taken in by the plant through the stomata from the environment. The oxygen is formed as a product of the process and is released in the environment. This process becomes impossible during the night because of the absence of sunlight. The entire process sums up to that the plants give out oxygen during the day and give out carbon dioxide during the night.

Answer:

Galapagos finches have various beak sizes that make foraging for food more successful.

Explanation:

Organisms evolve over time due to changes in their genome. These are pontaneous, and occur in DNA at random. These changes are called mutations and form alleles or different forms of a gene.

Over time within a population, the number alleles increase the variation of the population. These variants may confer specific traits within an individual, that may confer a biological advantage.

Thus, the trait may make the organisms more capable of obtaining food, shelter a mate etc. or ensure survival, i.e. they are able to pass on their genes to the next generation.

An opportunistic predator switches prey, capturing whichever prey species is most abundant. As soon as the prey numbers dwindle

Sunny_sXe [5.5K]

Answer:

The correct answer is keystone predator.

Explanation:

In sustaining the composition of an ecological community, a keystone species plays an essential function. In the absence of keystone species, the ecosystem would fail to exist and would become drastically different. A predator is a classic illustration of a predator, which inhibits a specific herbivorous species from eradicating the dominant species of plants. In the non-existence of predators, the herbivorous prey would increase enormously and would clean the entire essential plant species, and thus, drastically change the significance of the ecosystem.
