Answer:
Because each subject in an experiment has to have equal conditions to ensure the most accurate results. And water temperature is known to impact plant growth. An experiment using different water temperatures is a terribly inaccurate experiment.
Answer:
A Mutation is when a DNA gene is damaged or changed in a way that changes the genetic message carried by that gene.
Explanation:Mutations are sometimes good and sometimes bad it can also cause genetic variation which increases the survival of a species
Answer:Changes that affect the structure of chromosomes can cause problems with growth, development, and function of the body's systems. These changes can affect many genes along the chromosome and disrupt the proteins made from those genes.
Structural changes can occur during the formation of egg or sperm cells, in early fetal development, or in any cell after birth. Pieces of DNA can be rearranged within one chromosome or transferred between two or more chromosomes. The effects of structural changes depend on their size and location, whether gene function is interrupted, and whether any genetic material is gained or lost. Some changes cause health problems, while others may have no effect on a person's health.
Explanation: took the test
Answer:
B. Cells in Alex’s body underwent mitosis to create new tissue
Explanation:
Mitosis is the cell division that forms two genetically identical daughter cells from one parent cell. It occurs in somatic cells and is responsible for the growth and development of individuals.
Alex gained the height as the cells in tissues of his body underwent the mitosis and produced new daughter cells. Repeated cycles of mitosis added a large number of new cells to his body to form new tissues in his body parts and caused an increase in his height.
Answer:
Aftershocks are sometimes just as hazardous as the main quake itself. In fact, aftershocks may be so strong that they're stronger than the main quake. ... While foreshocks occur around the same time of the main quake, aftershocks may not occur until days or weeks later! The point at the Earth's surface directly above the focus is called the epicenter of the earthquake. At the epicenter, the strongest shaking occurs during an earthquake.
Hope this helps, have a great day/night, and stay safe!
