Answer:
The correct answer is ecological succession.
Explanation:
For the growth and development of an ecosystem, the phenomenon of ecological succession plays an essential role. A slow procedure by which the ecosystems modify and develop with time is termed as the ecological succession. There are prime two kinds of succession, that is, primary succession and secondary succession.
The phenomenon of ecological succession helps in the colonization of the novel areas, and in the recolonization of the destructed ecosystems, this helps the species to get amend with the modifications taking place in the surroundings and helps them to thrive. The given case is an illustration of ecological succession as the flowing of lava creates barren land, which further helps in the establishment of the pioneer plants. These pioneer species of plants helps in the development of a new ecosystem.

allele frequencies?
Answers
To find the number of heterozygotes in a sample population, we need to know the allele frequencies and the total number of individuals in the population. The formula used to calculate the expected number of heterozygotes in a population is based on the Hardy-Weinberg equilibrium principle.
The Hardy-Weinberg equation is given as:
p² + 2pq + q² = 1
Where:
p = frequency of one (dominant) allele
q = frequency of the other allele (recessive) allele
p² = expected frequency of homozygous dominant individuals
2pq = expected frequency of heterozygous individuals
q² = expected frequency of homozygous recessive individuals
To find the number of heterozygotes, we can multiply the expected frequency of heterozygotes (2pq) by the total population size. This will give us an estimate of the number of individuals in the population who are heterozygous for the specific gene of interest.

Explanation:
The frequency of heterozygous individuals. Answer: The frequency of heterozygous individuals is equal to 2pq. In this case, 2pq equals 0.32, which means that the frequency of individuals heterozygous for this gene is equal to 32% (i.e. 2 (0.8)(0.2) = 0.32

Answers
The correct answer is A. Asthenosphere.
Explanation
The earth is composed of three large layers: the nucleus, the mantle, and the crust. However, there are more layers within the main layers; in the case of the the asthenosphere, this is a layer of semi-molten materials that is located under the lithosphere (50 to 150km of depth) and has a thickness of around 650km. Additionally, this is located above the mesosphere, another layer of the crust that is part of the mantle, and extends to approximately 2700km deep. Additionally, this layer serves as a transition between the lithosphere and the mesosphere which are two major layers. So, the correct answer is A. Asthenosphere.

Threonine contains two functionalgroups: an amino group (-) and a hydroxyl group (-OH).
These functionalgroups are responsible for the molecule's properties and reactivity. The amino group is part of the amino acid structure, while the hydroxyl group is characteristic of alcohols.
The carboxyl group (-COOH) is another functionalgroup present in threonine. It is acidic in nature and can donate a proton, making threonine capable of acting as a weak acid.
The hydroxyl group (-OH) attached to the side chain of threonine is an alcohol functional group. It provides threonine with unique chemical properties.
Thus, threonine contains two distinct functional groups: an amino group (-) and a hydroxyl group (-OH).

Prometaphase (late prophase)
Explanation:
Mitosis is the kind of cell division in which two genetically identical copies of a cell is formed from a cell. Mitosis comprises of stages which include prophase, metaphase, anaphase and telophase. Each phase is characterized by specific occurrences that all work together to achieve the main goal of forming two daughter cells.
According to this question, PROPHASE stage is the stage characterized by the condensation of chromatids into chromosomes, the disappearance of nucleolus and BREAKDOWN of NUCLEAR MEMBRANE.

The correct answer is option B. Devonian.
The amphibians are the tetrapods (having four limbs), which can live in both water and land, but for reproduction purpose, they need water and early life is exclusively aquatic. The amphibians are known to be evolved from lobbed finned fishes around 370 million years ago in the Devonian period of the Paleozoic Era.
