What is Salmonella?

Salmonella is bacteria responsible for more hospitalizations and deaths than any other type of bacterium or virus found in food. However, not all bacteria make people sick. Many bacteria live on and in our bodies without causing harm or being attacked by our immune systems, including the bacteria in our digestive systems that help break down food.

What is mitosis? What is the importance of mitosis?

Mitosis is the process in which one eukaryotic cell divides into two cells identical to the parent cell (generally identical, since alterations in genetic material can occur, and a smaller or larger number of organelles may be distributed between the daughter cells, etc.) Mitosis is fundamental for the asexual reproduction of eukaryotes, for embryonic development, for the growth of pluricellular organisms and for tissue renewal.

Solve the equation 5(-3x - 2) - (x - 3) = -4(4x + 5) + 13

Given the equation 5(-3x - 2) - (x - 3) = -4(4x + 5) + 13 Multiply factors. -15x - 10 - x + 3 = -16x - 20 +13 Group like terms. -16x - 7 = -16x - 7 Add 16x + 7 to both sides and write the equation as follows 0 = 0 The above statement is true for all values of x and therefore all real numbers are solutions to the given equation.
