24 i think
Answer:
B. 24
Explanation:
There are 24 atoms in one molecule of C6 H12 06. This chemical compound is made up of 6 atoms of carbon, 12 atoms of hydrogen, and 6 atoms of oxygen. We find the number of atoms by adding these numbers up. We than get:
6 + 12 + 6 = 12 + 12 = 24
Therefore, there are 24 atoms in the following chemical formula.
What groups of animals are heterotrophs?
a.) herbivores
b.) carnivores
c.) omnivores
d.) all the above
Answer:
All of the above.
Explanation:
As a review, remember that carnivores eat other animals and omnivores eat both plants and animals. There is yet another term used when talking about food chains, the word heterotroph. Anything that is not an autotroph is a heterotroph. The word means “other feeding” or feed off of others.

the solubility of sugar is 30 degree Celsius at 220 what does it mean
Answer:
So, that if you put 100 mL of 30 degree water in a beaker, you could add up to 220 grams of sugar and it would eventually dissolve. In other words, that mass of sugar should dissolve in 100 mL of water to make a solution that is just saturated.
The solubility of sugar is 30° C at 220. This means 220g of sugar is dissolved in 100g of solvent to make the saturated solution at 30° C. Solutions.
What is the solution?Most frequently, the solubility is represented in terms of mass per volume of water. Solubilities are frequently stated as g/100 mL, g/100 g, or g/L of water.
The ratio you provided is probably 1 g of sugar to 100 mL of water. In other words, if you put 100 mL of water at 30 degrees in a beaker, you could add up to 220 grams of sugar, and it would finally dissolve.
To generate a solution that is just saturated, the mass of sugar should dissolve in 100 mL of water.
Therefore, at 220 degrees, sugar dissolves at 30 degrees. This indicates that to create the saturated solution at 30° C, 220g of sugar must be dissolved in 100g of solvent.

4. A cylindrical tube has a length of 14.4cm and a radius of 1.5cm and is filled with a colorless gas. If the density of the gas is known to be 0.00123g/cm', what is the mass of the gas in the tube in mg?
Answer:
Mass, m of gas is 0.2504 grams.
Explanation:
First, we need to solve for the volume of the cylindrical tube.
Volume of cylinder is given by the formula;
[tex] V = 2\Pi r^{2}h[/tex]
Where, V represents volume.
π represents pie
r represents radius.
h represents height or length.
Given the following data;
Radius, r = 1.5cm
Length, h = 14.4cm
Density, d = 0.00123g/cm³
Substituting into the equation;
[tex] V = 2 * 3.142 * (1.5)^{2}14.4[/tex]
[tex] V = 2 * 3.142 * 2.25 * 14.4[/tex]
[tex] V = 203. 6016[/tex]
Therefore, the volume of the cylindrical tube is 203. 6016cm³
Density can be defined as mass all over the volume of an object.
Simply stated, density is mass per unit volume of an object.
Mathematically, density is given by the formula;
[tex]Density = \frac{mass}{volume}[/tex]
[tex] Mass = density * volume [/tex]
Substituting into the equation, we have;
[tex] Mass = 0.00123 * 203. 6016 [/tex]
Mass = 0.2504g.

A racehorse coming out of the gate accelerates from rest to a velocity of 12.0
m/s due west in 2.30 s. What is its average acceleration?
27.6 m/s^2
5.22 m/s^2
-5.22 m/s^2
-27.6 m/s^2
-0.19 m/s^2
O 0.19 m/s^2
Answer:
5.22 m/s²
Explanation:
From the question given above, the following data were obtained:
Initial velocity (u) = 0 m/s
Final velocity (v) = 12 m/s
Time (t) = 2.3 s
Acceleration (a) =.?
Acceleration is defined as the change of velocity with time. Mathematically, it is expressed as:
Acceleration (a) = final velocity (v) – initial velocity (u) / time (t)
a = (v – u) /t
With the above formula, we can obtain the acceleration of the racehorse as follow:
Initial velocity (u) = 0 m/s
Final velocity (v) = 12 m/s
Time (t) = 2.3 s
Acceleration (a) =.?
a = (v – u) /t
a = (12 – 0) / 2.3
a = 12 /2.3
a = 5.22 m/s²
Therefore, the average acceleration of the racehorse is 5.22 m/s²
Which statement is true about magnetic field lines?
O A. They point toward the north pole of a magnet and away from the
south pole.
OB. They point toward the south pole of a magnet and away from the
north pole
O C. They loop from the south pole to the south pole and from the
north pole back to the north pole.
OD. No consistent pattern exists in the lines.
Answer:
It’s option B
Explanation:
Magnetic field lines are defined to have the direction that a small compass points when placed at a location. If small compasses are used to map the magnetic field around a bar magnet, they will point in the directions shown: away from the north pole of the magnet, toward the south pole of the magnet.
The magnetic field lines are the points towards the south pole of magnet and are away from the north pole. Thus, option B is correct.
What are magnetic field lines?A North magnetic pole would move along magnetic field lines, which are lines drawn in a magnetic field. Magnetic lines of force are another name for the magnetic field lines.
The north pole serves as the starting point for magnetic lines of force, which end at the south pole. They won't ever cross over each other.
Small compasses will point away from the magnet's north pole and toward its south pole when used to map the magnetic field surrounding a bar magnet.
Therefore, the magnetic field lines are given to have direct attention away from the north pole of a magnet and toward its south pole.

Write a brief summary of table tennis or tennis
Answer:
A point is won by a player when the opponent cannot hit the ball with a racket over the net and onto the other side of the table. Each game is won by being the first player to win 11 points, and be at least 2 points ahead of their opponent. The equipment needed to play table tennis would be a table, rackets, and balls. Some of the rules are no hand-on table (even leaning your hands on the table is not allowed!) Also, if the ball hits the net, you have to serve again.

The gradual change in a species over time is called
a.
mutation.
b.
evolution.
c.
migration.
d.
variation.
PLZ HURRY WILL GIVE BRAINLIEST
Answer: B. Evolution
Explanation:
As species grow older over time they will gradually evolve through natural selection and evolution.
The gradual change in a species over time is known as evolution (b).
The process of evolution occurs through several mechanisms, including mutation, migration, and natural selection.
Mutation (a) is the spontaneous change in the genetic material of an organism. These changes can result in new traits that may be advantageous, disadvantageous, or neutral for survival. When mutations occur, they can introduce genetic variation within a population, which serves as the raw material for evolution.
Natural selection is a crucial factor driving evolution. Individuals with advantageous traits that better suit their environment are more likely to survive and reproduce, passing on these advantageous traits to their offspring. Over generations, the frequency of beneficial traits increases in the population, leading to the adaptation and evolution of the species.
Variation (d) encompasses the differences in physical traits and genetic makeup among individuals within a population. This variation is essential for evolution to occur since it provides the raw material for natural selection to act upon.

Sound moves faster in warmer air than colder air the way bends away from the warm air and back towards of air.
Answer:
Sound travels slower in cold temperatures than in hot temperatures because the particles in cold air are more closely compacted together and move slower compared to the particles of hot air. Thus the sound, vibrations of particles in the atmosphere, will travel slower.
