Answer:
Primary succession is one type of the ecological succession which takes place on the land devoid of vegetation or barren land.
The species which first flourishes on this barren land are known as pioneer species which includes the species of bryophytes and pteridophytes like lichens and mosses.
These lichens and mosses help breakdown the barren rocks through chemical leaching and help increase the nutrient content. This allows the ferns and small pteridophytes to grow.
Then the area is colonized by the intermediate species which includes herbs, shrubs later trees. These intermediate species help attract the animals and thus help establish the biological community.
Thus, Lichens mosses → herbs→ shrubs →trees.

Answer:
In cabbage butterflies, White wings are dominant to yellow wings. Create a Punnett Square that shows the offspring that results if a Ww butterfly is crossed with a ww butterfly. Create a Punnett Square. What percentage of the offspring will have yellow wings? and What is the phenotypic ratio (color ratio)?
Ww x ww= Ww, Ww, ww, and ww
50% has yellow wings
The phenotypic ratio is two white wings butterflies and two yellow wing butterflies 2:2 50%:50%
Explanation:
Answer:
An atom is composed of two regions: the nucleus, which is in the center of the atom and contains protons and neutrons, and the outer region of the atom, which holds its electrons in orbit around the nucleus.
Explanation:
C) Heterozygous In a punnet square it will have a 100% chance of being heterozygous dominant.
