There are two types of succession that lead to the increasment of the ecosystem:
1. Primary succession is the change in the structure of an ecosystem represented with the increase of the ecological community on an area that has not been previously occupied by an ecological community such as area after the lava flow or glacial lake. The first organisms of primary succession are pioneer plants usually, lichens and mosses.
2. Secondary succession includes the step of removal of pre-existing community and after that, colonization of the new one.
Answer:
25% or 1/4
Explanation:
The gene for colour in Heliodors is controlled by two contrasting alleles that codes for Red (R) and Yellow (Y) colours. However, these two alleles exhibit incomplete dominance, which is a phenomenon whereby a combination of both alleles gives rise to a third intermediate phenotype that is a blending of the other two parental phenotypes. In this case, both colours gives rise to a heterozygous Orange coloration (RY) in Heliodors.
However, if two orange Heliodors (RY) are crossed, four possible offsprings will be produced with the genotypes: RR, RY, RY, YY. This shows a phenotypic ratio of 1 red: 2orange: 1yellow. Hence, the probability of having a child with red coloration is 1 out of 4 possible offsprings i.e. 1/4.
Expressing this in percentage, we have 1/4 × 100 = 25%.
It’s TAGCGTTAA they are complementary
Both are found in all eukaryotic cells is the one among the following choices given in the question is not one of the features that is common in mitochondria and chloroplasts.

Answer:
No.
Explanation:
No, the stone did not take the shape of the glass because stone is not a liquid, it is a solid. Taking the shape of the container in which it is placed is the property of liquid matter whereas the solid maintain its shape and structure when placed in any container. No, the stone did not change the shape and structure when it is placed in the pail due to its solid matter. The properties of matter are the following: It is composed of tightly packed particles which make the matter solid. It maintains its shape and its particles can't move freely like gas and liquid particles.
