Endocrine glands make chemicals called hormones and pass them straight into the bloodstream. Hormones can be thought of as chemical messages. From the blood stream, the hormones communicate with the body by heading towards their target cell to bring about a particular change or effect to that cell
Answer: The correct answer to the question is option E
BOTH ANAEROBIC RESPIRATION AND CREATININE PHOSPHATE BREAKDOWN.
Explanation: 50 meter dash is a race,a form of exercise, energy is required as well as muscle contraction and chemical processes.
Alex muscles will rely on the following chemical processes during the race;anaerobic respiration and creatine phosphate breakdown.
These chemical processes are explained below;
Aerobic respiration uses oxygen to generate energy but unlike aerobic respiration, anaerobic respiration breaks down glucose to provide energy and create adenosine triphosphate(ATP), lactic acid and ethanol.
Muscle contraction cannot take place without the supply of energy by ATP, molecules can store energy in it's phosphate form, this molecule is known as creatine phosphate,when this happens,ATP that is in excess will then transfer it's energy to creatine,this action will produce creatinine phosphate and adenosine diphosphate (ADP) and they will now be stored as reserve of energy that can be used to produce more ATP and thus energy is produced.
Species is the basic unit of classification denoted by a unique two-part scientific name.
<h3>What is meant by species? </h3>
Species is a name given to a group of organisms which have similar individuals. They are capable of reproducing among themselves and thus exchanging genes among themselves.
Species is the lowest of taxa and is thus the most basic unit of classification. Genus is the next taxonomic rank of the next taxa on the hierarchy of classification.
It is estimated that on earth, there are 8.7 million species living currently. This concept of species is from the times of Aristotle.
Therefore, species is the basic unit of classification denoted by a unique two-part scientific name.
