Answers

Answer 1

Answer:

Answer:

Some differences between primary and secondary succession are:

-Secondary succession happens on a previously existing community that has been cleared.

Another difference would be:

-Pioneer species for secondary succession are adapted differently- they grow quickly, can disperse quickly and have a short life span

And finally:

-Primary succession develops a new community from scratch

Clownfish have evolved resistance to the deadly stings of sea anemones. The sea anemone provides protection for the clownfish from predators and leaves the uneaten remains of its prey for the clownfish to finish off. Meanwhile the clownfish helps attract prey to the sea anemone with its bright colors. The relationship between clownfish and sea anemones is a form of symbiosis called?

Answers

The answer is mutualism.

Mutualism is a relationship between two different species in which both species benefit. In clownfish - sea anemone relationship, the clownfish is protected from predators by the sea anemone, so the clownfish benefits from this relationship. The sea anemone gets more prey thanks to a coloration of the clownfish, so the sea anemone also benefits from this relationship. Since both species benefit, their relationship is an example of mutualism.

Answer:

mutalism

Which is the significance of the tunica in plant growth? In the tunica, cell divisions are perpendicular to the stem axis, giving rise to thick layers of tissues covering the outside of the tip. In the tunica, cell divisions are parallel to the stem axis, giving rise to thick layers of tissues covering the inside of the tip. In the tunica, cell divisions are parallel to the stem axis, giving rise to thin layers of tissues covering the inside of the tip.

Answers

The answer is In the tunica, cell divisions are perpendicular to the stem axis, giving rise to thick layers of tissues covering the outside of the tip.

The tunica is a membranous structure which covers the plant organs. It is responsible for the characteristics of leaf edges and margins in the monocots. During the plant growth, perpendicular cell divisions regarding the stem axis result in the membranous structure outside of the tip.

At the present time both populations have the same number of individuals in which of these countries will the population growth over the next 20 years place the greatest strain on the enviorment

Answers

The diagram shows the current percentage of each population by age and gender (male/female) for two countries. After carefully analyzing the graph I came with the conclusion that:

(1) Country A, the population growth over the next 20 years will place the greatest strain on the environment since the larger percentage of young people could result in rapid population growth.

I hope this helps, Regards.

Choose the correct order of classifying organisms in the Linnaean system. A.kingdom→phylum→ class→ order→ genus→ family → species B.kingdom→phylum→class→order→family→genus→species C.species→order→family→genus →class →phylum→kingdom

Answers

The correct answer is option B, kingdom→phylum→class→order→family→genus→species

Reason:

There are basically seven orders of classification in Linnaeus's Classification System (in present time) arranged in descending order

Kingdom→phylum→class→order→family→genus→species

The Domain is the largest and most inclusive group and consists of organisms that share few characteristics while the species is the smallest and most exclusive group and consists of organism that possess similarity up to an extent where they can breed among themselves to produce offsprings.

The answer is B. You can remember it by King Phillip Came Over For Galloping Stallions.
