– DNA undergoes transcription to become RNA. RNA undergoes translation to become protein. – Ribosomes contain RNA – Proteins are large molecules with smaller amino acids in them. – The nucleus of a cell contains chromosomes. The chromosomes have DNA wrapped in proteins.
The center of an atom is a nucleus. In the nucleus, there are 2 subatomic particles: protons (positive charge) and neutrons (neutral charge). Outside of the nucleus are electrons. The energy of an electron is in shells. An atom is a single nucleus with a positive charge surrounded by a cloud of negatively charged electrons.[…]
A circuit is a complete path that electricity flows through. There is a source of electricity (battery). Conductors are the materials that allow electric current to pass through them easily. Conductors like the positive and negative ends of a battery. In a closed circuit, the electricity flows without any interruptions. Ohm’s Law: Voltage (V); Current[…]
1. Newton’s First Law: An object that is at rest will stay at rest unless a force acts upon it. An object that is in motion will not change its velocity unless a force acts upon it. 2. Newton’s Second Law: Force = mass * acceleration. The second law states that the rate of change[…]
Sally is staying at a hotel that charges $88.50 per night plus tax. A 6% tax is applied to the room rate, and an additional onetime untaxed fee of $7.00 is charged by the hotel. Write an expression for Sally’s total charge, in dollars, for staying x nights.
x² + y² = 167 y = −3x Solve for x and y.
The function h is defined by h(x) = 6x³ + 9x² + 3cx + 24, where c is a constant. If (-4, 0) is one of the x-intercepts of h, what is the value of c?
Find the value of x: 4x + x + x + x + x − 9 − 3 = 8 + x + x + x
y > 4x − 2 6x > 15 Find the y-coordinates of all the points that satisfy this system of inequalities.
234 people went on a camping trip, taking 68 tents with them. Some of the tents held 2 people, and the rest held 4 people. If all the tents were filled to capacity and every person slept in a tent, how many of the tents were 4-person tents?
