When we drink water, it is absorbed into our blood through the digestive tract. If the concentration of water in body cells is low, cells must get water from the blood. What process allows water to enter body cells from the blood?
Answer:
Osmosis
Explanation:
Water is very essential for the body. When we drink water, our blood cells absorbs water from the body. This happen by a process called as osmosis process. Osmosis is type of diffusion process.
Water along with oxygen and carbon dioxide are some of the simple molecules that moves into the blood cell. Osmosis is the process by which water molecules passes into the cell bodies through its semi permeable membrane.

Do I use molar mass when the problem gives me grams? (Yes or No), Right answer gets brainliest.
(Stoichiometry Review)
Answer:
yes
Explanation:
yes because the molar mass is an intensive property of the substance, that does not depend on the size of the sample. In the International System of Units (SI), the base unit of molar mass is kg/mol. However, for historical reasons, molar masses are almost always expressed in g/mol.
Answer:
Yes, if your calculating from grams to moles.

What is the energy of a radio wave whose frequency is 6.2 x 106 Hz?
Answer:
657.2 Hz
Explanation:
Please help me vote you brainiest
Answer: D
Explanation: P = W/t
W = F d
When dividing, if you have a large number over a small, you get a large number. We want a small number, so we want the opposite for our P : W/ t formula. We want a small Work and a large time.
Right off the bat, the two with the least time aren't right then.
From there, we can estimate how much work it would take using the W = F d equation. If there is a small distance, there is less work, which is what we want to achieve a small work over large time.
So, the choice with the most time and the least distance should be correct.

Mercury is an element that forms during _____
Answer:
forms of mercury
Explanation:
Answer:
Explanation:
Mercury is an element and a metal that is found in air, water, and soil.Mercury rarely occurs uncombined in nature, but can be found as droplets in cinnabar (mercury sulfide) ores. China and Kyrgyzstan are the main producers of mercury. The metal is obtained by heating cinnabar in a current of air and condensing the vapour.

1. What three characteristics determine the type of sedimentary rock?
Answer:
Characteristics of Sedimentary Rocks. ● The color of the sedimentary rock is determined by the content of the strata that were pressed together to form it. If the layers have a high organic content, the rock is usually gray to black in color. On the other hand, high amount of minerals give the rock the color of the mineral.

Blaire is teaching her little brother to ride his bike. She uses 7 N of force to push a 14 kg bike. What is the acceleration?
98 m/s2
0.5 m/s2
21 m/s2
2 m/s2
Answer:
The solution is
Explanation:
a = f/m
a =7/14
a=1/2
a=0.5
Acceleration of bike is 0.5 m/s²
Given that:Force used in push = 7 N
Mass of bike = 14 kg
Find:Acceleration of bike
Computation:Force = Mass × Acceleration
Force used in push = Mass of bike × Acceleration of bike
7 = 14 × Acceleration of bike
Acceleration of bike = 7 / 14
Acceleration of bike = 0.5 m/s²

Two substances in a mixture differ in density and particle size. theses properties can be used to
Answer:
option 1. Two substances in a mixture differ in density and particle size. These properties can be used to separate the substances. These properties can be manipulated in order to have a better separation between the two substances.
Explanation:
Answer:
Two substances in a mixture differ in density and particle size. These properties can be used to separate both of them using the separating funnel or using filtration (filter paper).
Explanation:
Since their densities are different, one substance should float above the other in the mixture which allows for the separating funnel to let the substance sinking below (with the heavier density) to flow out first before changing the beaker to let the lighter substance flow out.
The substance with a bigger particle size would not be able to pass through the filter paper unlike the substance with the smaller particle size as the filter paper's pores is not big enough for it to pass through, separating both substances (with one on the paper and the other outside the filter paper, preferably in the beaker placed below the paper).

2. How many liters of propane gas (C3H8) will undergo complete combustion with 34.0 L of oxygen gas? ___ C3H8 (g) + ___ O2 (g → ___ CO2 (g + ___ H2O(g
Answer:
6.8 liters of propane gas will undergo a complete combustion with 34.0 L of oxygen gas.
Explanation:
Given;
combustion reaction of propane and oxygen;
C₃H₈ + O₂(g) → CO₂(g) + H₂O(g)
Balance the chemical reaction as follows;
C₃H₈ + 5O₂(g) → 3CO₂(g) + 4H₂O(g)
From the balanced equation;
1 mole of C₃H₈ ---------------- 5 moles of 5O₂(g)
x Liters of C₃H₈ ----------------- 34.0 Liters of O₂(g)
x = 34 liters / 5
x = 6.8 liters
Therefore, 6.8 liters of propane gas will undergo a complete combustion with 34.0 L of oxygen gas.
