Answer:
A. a base pare of deletion
Explanation:
A base pair deletion is a mutation where one nucleotide is removed during DNA replication. The base-pair deletions produce frameshift mutations, i.e., they cause genetic modifications that alter the Open Reading Frame (ORF) of the corresponding protein. Examples of human diseases caused by deletion mutations include, among others, cystic fibrosis and Williams syndrome.
Movement of cell against concentration gradient is called a.osmosis
Answer:
If leaf color change is related to temperature, then exposing plants to low temperatures will result in changes in leaf color:
Independent: <u>temperature</u>.
Dependent: <u>leaf color</u>.
Other variable(s): According to the information, <u>there are no other variables</u>.
Explanation:
When formulating a hypothesis, it is inevitable that the presence of variables on which the hypothesis is formed is established. The hypothesis raised is the <u>effect of temperature on the color change of the leaf of a plant</u>.
The<em> independent variable</em>, used in research work, is an element that does not depend on other variables but can influence the behavior of the dependent variable. In this case, the independent variable is the temperature. In addition, the independent variable can be managed to observe its effect on other variables.
An <em>dependent variable</em> is a characteristic that is influenced or modified by the presence of other variables, such as the independent variable of a study. In this case is the color of the leaf of a plant.
Answer:
Obsidian is an igneous rock that forms when molten rock material cools so rapidly that atoms are unable to arrange themselves into a crystalline structure. It is an amorphous material known as a "mineraloid." The result is a volcanic glass with a smooth uniform texture that breaks with a conchoidal fracture (see photo).
