Answer:
All human beings are 99.9 percent identical in their genetic makeup. Differences in the remaining 0.1 percent hold important clues about the causes of diseases.
Explanation:
Our bodies have 3 billion genetic building blocks, or base pairs, that make us who we are. And of those 3 billion base pairs, only a tiny amount are unique to us, making us about 99.9% genetically similar to the next human.
Our bodies have 3 billion genetic building blocks, or base pairs, that make us who we are. And of those 3 billion base pairs, only a tiny amount is unique to us, making us about 99.9% genetically similar to the next human.
What is genetics?
The study of genes and heredity. Heredity is passing genetic information and traits (such as eye color and an increased chance of getting a particular disease) from parents to offspring.
What is the role of genetics?
Genetic research studies how individual genes or groups of genes are involved in health and disease.
Thus, out of 3 billion base pairs, only a tiny amount is unique to us. So humans are genetically similar.

Mycobacterium tuberculosis is the bacteria that causes tuberculosis (TB). Although the TB germs typically assault the lungs, they can also affect the kidney, spine, and brain.
Explain about the Mycobacterium tuberculosis?Mycobacterium tuberculosis is a type of bacteria that causes tuberculosis (TB). When a person with active TB disease in their lungs coughs or sneezes, TB bacteria-containing droplets that are ejected are inhaled by the other person.
Mycobacterium tuberculosis complex bacteria, which are members of the order Actinomycetales and family Mycobacteriaceae, are the primary cause of tuberculosis (TB). The most prevalent cause of sickness in humans is M. tuberculosis, one of the species in the M. tuberculosis complex.

Sadie buys 6 postcards and 4 souvenir magnets for $ 16.90. Cruz buys 3 postcards and 3
magnets for $ 10.80. Which system of linear equations can be used to solve for the cost
of each postcard, p, and each magnet, m?
Taking into account the definition of a system of linear equations, the cost of each postcard and the cost of each magnet are 1.25 and $2.35 respectively.
System of linear equationsA system of linear equations is a set of two or more equations of the first degree, in which two or more unknowns are related.
Solving a system of equations consists of finding the value of each unknown which when replacing, all the equations of the system are satisfied.
Cost of each postcard and each magnetIn this case, a system of linear equations must be proposed taking into account that:
"p" is the cost of each postcard."m" is the cost of each magnet.You know:
Sadie buys 6 postcards and 4 souvenir magnets for $ 16.90. Cruz buys 3 postcards and 3 magnets for $ 10.80.The system of equations to be solved is
6p + 4m= 16.90
3p + 3m=10.80
There are several methods to solve a system of equations, it is decided to solve it using the substitution method, which consists of clearing one of the two variables in one of the equations of the system and substituting its value in the other equation.
In this case, isolating the variable "m" from the second equation:
3m=10.80 - 3p
m= (10.80 - 3p)÷3
m= 3.6 - p
Substituting this expression in the first equation:
6p + 4×(3.6 - p)= 16.90
Solving:
6p + 4×3.6 - 4p= 16.90
6p + 14.4 - 4p= 16.90
6p - 4p= 16.90 - 14.4
2p= 2.5
p= 2.5÷2
p= 1.25
Remembering that m=3.6 - p, you get:
m= 3.6 - 1.25
m= 2.35
Finally, the cost of each postcard is $1.25 and the cost of each magnet is $2.35.

How does the body protect its iron stores when iron stores are low?
The body can store a small amount of extra iron in a protein found in red blood cells called ferritin.
Iron absorption has been shown to be improved by vitamin C. It binds to non-heme iron and stores it in a form that your body can easily absorb. The mechanisms that regulate systemic iron homeostasis are largely focused on the liver and involve two molecules, hepcidin and ferroportin, which collaborate to regulate the flow of iron from cells into the systemic circulation.
Iron deficiency is commonly caused by a lack of iron in the diet, chronic blood loss, pregnancy, and strenuous exercise. Iron deficiency occurs when some people are unable to absorb iron. Iron deficiency can be treated by consuming iron-rich foods.

Less than and equal to the optimum temperature, any increase in the reaction temperature leads to a decrease in its rate is not true regarding enzymatic reactions.
Factors affecting enzyme
The reaction that enzymes catalyse receives activation energy from them.
Temperature is one of the elements impacting enzymes. Substrate molecules start to move more quickly as the temperature rises. By increasing the number of substrate molecules that come into contact with the enzymes' active sites, more substrate can bind.
The enzyme's active sites must be free for the velocity to be at its highest level.

The electron transport chain is a set of protein complexes and other molecules that connect protons (H⁺ ions) through a membrane with the transfer of electrons from electron donors to electron acceptors via redox reactions.
It is an exergonic procedure for electron transport. Adenosine triphosphate is synthesized as a result of an electrochemical proton gradient created by the redox reaction energy (ATP). The chain is an energy converter that pumps H⁺ from the mitochondrial matrix to the intermembrane space via the exergonic flow of electrons from NADH to FADH₂. The H⁺ is prone to return across the membrane, dispersing its gradient on its own. And the only regions that allow H⁺to pass through the membrane are the ATP synthases.

Red blood cells' hemoglobin component enables them to carry oxygen to tissues all over your body.Red blood cells' sickle shape can cause a number of difficulties. They can get caught inside blood arteries because of their atypical structure, resulting in uncomfortable symptoms.Furthermore, sickle cells age more rapidly than regular red blood cells, which can cause anemia.What are dominant and recessive allele?
