Answer:
Look below plz :))
Explanation:
1.) In a chemical change, the molecules in the reactants interact to form new substances. In a physical change, like a state change or dissolving, no new substance is formed. Explain that another way to say that no atoms are created or destroyed in a chemical reaction is to say, “Mass is conserved.”
2.) Carbon Dioxide and Water Out: During combustion, the atoms in ethanol and oxygen are rearranged into carbon dioxide and water. The carbon dioxide and water leave the top of the flame.
Answer;
A. gases or particles present in high enough concentrations in the atmosphere to harm humans, other organisms and structures.
Explanation;
Air pollution is a type of pollution that occurs when harmful or excessive substances such as particulates, gases and biological molecules are introduced into Earth's atmosphere.
The burning of fossil fuels, such as coal, oil, natural gas, and gasoline to produce electricity and power our vehicles is the major cause of air pollution.
Answer: adenosine triphosphate (ATP) - the high energy chemical compound with three phosphate groups that provides energy for all other cell activities
endocytosis - when cells engulf or ingest substances
cellular respiration - chemical reactions in plants and animals that break down food molecules into energy (ATP)
movement of particles or molecules from higher concentration to lower concentration - diffusion
when cells expel or get rid of substances from within- exocytosis
a solution that has a higher salt concentration than the salt - hypertonic
the relatively constant state in the internal environment of an organism - homeostasis
Explanation:
Adenosine triphosphate or ATP is the energy currency that is required for providing energy for metabolic functions and activities in the body.
Endocytosis can be defined as the process through which a cell engulfs another cell or substances to get rid of them.
Cellular respiration can be defined as the process through which the food in the organisms is oxidized and broken into parts to release energy.
Diffusion involves the movement or transfer of gas, liquid, and solid particles from a region of higher to lower concentration without the requirement of semi-permeable membrane.
Exocytosis is a process in which the cell releases those substances that are required by the cell.
Hypertonic is a solution that has more solute concentration than solvent concentration.
Homeostasis is a tendency to maintain constancy in the internal environment of body in relation to changes occurring in the surrounding.
Go to the Prenatal Testing page for more details. If one parent has sickle cell trait (HbAS) and the other has sickle cell anaemia (HbSS) there is a one in two(50%) chance that any given child will get sickle cell trait and a one in two chance that any given child will get sickle cell anaemia.
