The answer is evolving.
Some of the conditions that must be met for a population to be in Hardy-Weinberg equilibrium are:
1. The population must be very large.
2. There must be no migration and population must be isolated - stagnant population.
3. There must be no mutations - stable population.
4. There must be random mating, which means there are no mating preferences.
According to this evolving population is not in Hardy-Weinberg equilibrium.

Answer:
DNA molecule
Explanation:
In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
True, individuals with familial Down Syndrome are trisomic and have 47 chromosomes. This occurs when there's an extra copy of chromosome 21 as a result of a parent carrying a rearranged chromosome, or translocation.
True. Individuals with familial Down Syndrome are indeed trisomic, which means they have an extra copy of a certain chromosome. In the case of Down Syndrome, there's an extra copy of chromosome 21, resulting in a total of 47 chromosomes instead of the usual 46. People inherit this condition through familial Down Syndrome when one parent carries a rearranged chromosome, referred to as a translocation. In this type of Down syndrome, there are three copies (i.e., trisomic) of chromosome 21.

The correct answer is:
b. codominance
Explanation:
Codominance is a kind of dominance wherein the alleles of a gene set in a heterozygote are fully represented. This results in offspring with a phenotype that is not dominant nor recessive. A typical example telling codominance is the ABO blood group system.
Answer:
D- guard cells
The completed question is,
Identify the biotic factor of an ecosystem from the following:
a. soil composition
b. trees
c. temperature
d. sunlight
Option b. trees are the biotic factor of an ecosystem.
An ecosystem includes all the organisms and the physical environment with which they interact. These biotic and abiotic components exist linked together through nutrient cycles and energy flows. The energy penetrates the system through photosynthesis and exists incorporated into plant tissue.
The primary types of ecosystems are forests, grasslands, deserts, tundra, freshwater, and marine. The word “biome” may even be used to represent terrestrial ecosystems that extend across a large geographic area, such as the tundra.
With the provided choices. it exists trees that are categorized as biotic factors of an ecosystem. Biotic factor guides living things found in the ecosystem. Trees exist as living things that furnish oxygen for humans and animals to live.
Hence, Option b. trees are the biotic factor of an ecosystem.
