Answer:

B. Individuals within a population exhibit genetic variation and those that are best adapted to their environment survive.

Explanation:

Nature poses challenges time to time to all the living organisms in the form of harsh climate, scarcity of food, natural disasters such as floods, drought, etc. Such challenges enable some organisms to survive better than the others in the same environment and are said to be selected by the nature.

This capability to survive is also termed as fitness by some scientists. Darwin however only referred to the reproductive fitness which means those organisms who are better fit in their environment produce more number of offspring than others.

Darwin used the phrase "Natural selection" for this and said it is the natural selection which is responsible for evolution.

Answer:

Speciation was allopatric or peripatric, but would depend on the number of individuals that dispersed from the original populations.

Explanation:

There are two types of speciation: allopatric and peripatric.
Allopatric speciation occurs when the species of same population gets isolated that results in lack of gene flow.
From the isolated population, new species are formed then it is known as the peripatric speciation.
All these isolation of populations and formation of new species depends upon the initial or original group of species that was dispersed.

Where does organic and inorganic matter come from that is dissolved in ocean water? what about gases?

kvasek [131]

Answer:

Processes involving dissolved and particulate organic carbon are of central importance in shaping the chemical character of seawater. Marine organic carbon principally originates in the uppermost 100 metres of the oceans where dissolved inorganic carbon is photosynthetically converted to organic materials.

The right answer is hyphae for the first gap, mycelium for the second gap.

The hyphae constitute the vegetative apparatus of the mushrooms, while the visible part, that which is improperly called mushroom, is in fact its reproductive apparatus.

Hyphae are less branched filaments consisting of a single cell that can be several centimeters long. They contain several nuclei and can sometimes be partitioned.

The mycelium is a part of the mushroom (composed by many hyphae), which is in the form of white filaments and grows about fifteen centimeters under the ground. It is this part of the mushroom that has therapeutic properties because the filaments of the mycelium are going to draw the minerals in the soil.
