Answer:
The cell goes through the cell cycle/mitosis
Explanation:
The cell cycle is basically the process of dividing
G1 phase is where the cell grows in size, and make sure that everything is ready to divide.
Synthesis or the S phase is where the cell copies its DNA.
G2 phase is where the cells check that all its DNA has been correctly copied.
Mitosis or M phase, where the cell finally divides in two. If the cells keep on dividing exponentially, they will become billions of cells.

What is the mass of water released by the heating? Show your work or explain your reasoning.
Answer:
Dividing the mass of the water lost by the original mass of hydrate used is equal to the fraction of water in the compound. Multiplying this fraction by 100 gives the percent water in the hydrate.
Explanation:
The amount of water throughout the compound has been determined by dividing the mass of water wasted mostly by original quantity of hydrate used. The above fraction can be multiplied by 100 to get the hydrate's water content in percentages.
What is mass ?The proportion of matter that makes up an object is quantified by its mass. The kilogram, or kg, would be the fundamental SI unit of mass.
What is hydrate?Any substance that contains water through the form of H2O molecules is referred to as a hydrate. This water content by weight can vary, but it is typically fixed. The most well-known hydrates seem to be crystalline solids which decompose once the attached water is removed.
Therefore , The amount of water throughout the compound has been determined by dividing the mass of water wasted mostly by original quantity of hydrate used. The above fraction can be multiplied by 100 to get the hydrate's water content in percentages.

Temperature is a measurement of :
1) total energy in a system
2) the average kinetic energy of a system
3) the average potential energy of a system
4) the ability to do work
Answer:
Temperature is a measure of the average kinetic energy of the particles in an object. When temperature increases, the motion of these particles also increases. (That should give you the answer if you read closely first sentence)

What is a lattice position?
Explain
Explanation:
Crystallography. an arrangement in space of isolated points (lattice points ) in a regular pattern, showing the positions of atoms, molecules, or ions in the structure of a crystal.
If an atom experiences sufficient thermal activation, it can move to a neighboring lattice position.4 If the vibration frequency of the atom is v and the atom has Z nearest neighbors, the total number of jump attempts is vZ. However, only a small fraction of the attempts will be successful, with a probability depending on the ratio between the necessary activation energy for a single jump QD and the thermal activation kBT. The effective jump frequency ΓD is then
(5.6)
With each successful jump, the atom travels one atomic distance λ and the total traveling distance in unit time is thus ΓDλ. Substituting the jump frequency ΓD into the expression for the root mean square displacement of a random walker [equation (5.5)] and using the spatial coordinate r leads to

When collecting temperature as a function of time for the reaction of KOH with HCL, which time is most significant
Answer:
At the completion of reaction.
Explanation:
The time when the reaction take places is the most significant time for measuring temperature of the solution because on this time the temperature will decrease or increase. Some reactions releases heat energy upon completion we called them exothermic reactions whereas some absorb heat energy from the surrounding, decreases the temperature which is known as endothermic reaction so measuring temperature at the completion of reaction is the correct time.

Explanation:
Most of the deserts on the Earth are located around 30°N & 30°S latitude. This is because air is ( rising / sinking ) at these locations.
Answer: We live at the bottom of a gaseous envelope the atmosphere--that is bound gravity to the planet Earth. The circulation of our atmosphere is a complex process because of the Earth's rotation and the tilt of its axis. The Earth's axis is inclined 23.5° from the ecliptic, the plane of the Earth's orbit around the Sun. Due to this inclination, vertical rays of the Sun strike 23.5° N. latitude, the Tropic of Cancer, at summer solstice in late June. At winter solstice, the vertical rays strike 23.5° S. Latitude, the Tropic of Capricorn. In the Northern Hemisphere, the summer solstice day has the most daylight hours, and the winter solstice has the fewest daylight hours each year. The tilt of the axis allows differential heating of the Earth's surface, which causes seasonal changes in the global circulation. On a planetary scale, the circulation of air between the hot Equator and the cold North and South Poles creates pressure belts that influence weather. Air warmed by the Sun rises at the Equator, cools as it moves toward the poles, descends as cold air over the poles, and warms again as it moves over the surface of the Earth toward the Equator. This simple pattern of atmospheric convection.

Which is a disadvantage of using chemical indicators?
They are expensive to use.
They measure pH directly.
They must be selected for a narrow pH range.
They do not use electricity to operate.
WILL AWARD BRAINLIEST FOR FIRST CORRECT ANSWER!
Answer:
They must be selected for a narrow pH range.
Explanation:
Indicators are compounds that change to a specific colour in a solution within a specific pH range.
The chemical indicators does not give the exact value of pH. They only provide the range of pH. They must be selected for a narrow pH range. The correct option is C.
What is chemical indicator?The acid base indicators or neutralization indicators are substances which are employed for the visual detection of the end point on the basis of their ability to change colour during the pH change that occurs in vicinity of the end point.
The chemical indicators are usually weak organic acids or bases which change colour in characteristic pH ranges. The particular range or interval of pH in which an acid-base indicator changes its colour is known as the colour-change interval.
Methyl orange is a weak base which changes its colour in the pH range 3.1-4.4 being red below pH 3.1 and yellow above pH 4.4.
Thus the correct option is C.

list 2 ways mechanical energy can be transformed into non-mechanical energy ?
Answer:
One is the classic example of friction. When two surfaces rub together, they generate thermal energy, or heat. This is a transformation of the mechanical kinetic energy of the objects into the thermal non-mechanical energy (which is small-scale kinetic energy).
Mechanical energy can be used to overcome friction or lost in form of heat in machine parts. Friction and heat are two non-mechanical energy.
Transformation of mechanical energy into non mechanical energy
Based on the principle of conservation of energy, energy can neither be created nor destroyed but can be transformed from one form to another.
Two ways mechanical energy can be transformedThe two ways mechanical energy can be transformed include the following;
