The right answer is A.) nondisjunction
Non-disjunction is an absence of separation of two members of a pair of homologous chromosomes or chromatids from a chromosome during meiosis or mitosis, resulting in one of the daughter cells having two copies of the same chromosome or chromatids and the other daughter cell receives none.
In a controlled experiment, an independent variable (the cause) is systematically manipulated and the dependent variable (the effect) is measured; any extraneous variables are controlled. The researcher can operationalize (i.e. define) the variables being studied so they can be objectivity measured.
Cohesion, adhesion and surface tension are different from each other. Adhesion is used in xylem. Surface tension enables an insect to sit on water.
<u>Explanation:</u>
The force of attraction between the molecules of the same type is called cohesion. The force of attraction between the molecules of different type is called adhesion. Tendency of fluid surfaces to shrink to minimum possible area due to the attraction between the liquid molecules is called surface tension.
Adhesion is used in xylem. In xylem water molecules move from the roots to different parts of the plant through the xylem tubes. The adhesive force between the water molecules and xylem walls make the movement of water possible.
Surface tension enables an insect to sit on the surface of a liquid. Due to surface tension the water surface stretches like a membrane due to the higher attractive force between the water molecules.
Biotic factors that a population needs include food availability. Abiotic factors may include space, water, and climate. The carrying capacity of an environment is reached when the number of births equal the number of deaths. A limiting factor determines the carrying capacity for a species.
The answer to the question is false that is not true.
