which cells carry nutrients from food to the rest of the cells in the body?
Answer: The circulatory system.
Explanation: The circulatory system, which is part of the "cardiovascular" system, is one of the eleven organ systems of the human body. Its main function is to transport nutrients to cells and wastes from cells (Figure 3.4. 1). This system consists of the heart, blood, and blood vessels.
The blood cells carry nutrients from food to the rest of the cells in the body.
What is the circulatory system?The human circulatory system moves important nutrients and minerals throughout the body and metabolic waste products out from the body. The human circulatory system contains blood, blood vessels, heart, and lymph.
The human circulatory system provides essential nutrients, minerals, oxygen, and hormones to different parts of the body and is responsible for collecting toxins from the cells and tissues to be purified or eliminated from the body.
The human circulatory system contains a wide network of blood vessels. These constitute arteries, veins, and capillaries. The primary function of blood vessels is to transport nutrients and oxygenated blood to all parts of the body.
The Circulatory system helps in sustaining all the organ systems and transports blood, nutrients, oxygen, and hormones throughout the body. It secures cells from pathogens and acts as an interface for cell to cell interaction.

An irregular object with a mass of 18.00 kg displaces 2.50 L of water when placed in a large overflow container. Calculate the density of the object.
Answer:
7.20 kg/L
Explanation:
Density is mass (kg) / volume (L).
18.00kg/2.50L = 7.20 kg/L
If you need it in g/mL this is the equation:
[tex]\frac{7.20kg}{L} *\frac{1000g}{1kg} *\frac{1L}{1000mL} = 7.20g/mL[/tex]

When measuring the volume of a liquid, why is it best to use a measuring container that is narrow?
Answer:
n the sciences, the “tools” for measuring the volumes of liquids are generally made from glass, plastic or occasionally metal, although professionals referred to all of them as “glassware.” Scientists, and chemists in particular, have a variety of glassware at their disposal for measuring volumes. The particular piece of glassware chosen in any situation will depend primarily upon two factors: the required volume and the accuracy required for the measurement.

what is one way that the thermal energy of a system may be changed?
Answer:
In a open system, the thermal energy of a system may be changed by adding or removing matter with a different temperature.
Explanation:
The thermal energy of a system can be changed when a new substance of different temperature is introduced into the system
The thermal energy of a system is the amount of heat energy contained in that system.
The quantity of heat in a system is given as;
[tex]Q = mc \Delta \theta[/tex]
where;
[tex]\Delta \theta[/tex] is the change in the temperature of the system
When a new substance is introduced into the system, the temperature of the resulting system changes.
For example;
a hot iron introduced into a cold water, will increase the temperature of the water thereby increasing the thermal energy of the water.Thus, the thermal energy of a system can be changed when a new substance of different temperature is introduced into the system.

A gamma ray has a frequency of 1 x 10^20 Hz and has a speed of c. What is the
wavelength?
Answer:
λ = 3.0 × 10⁻¹² m
Explanation:
Speed of Light = Wavelength × frequency
c = λν
Step 1: Define
c = 3.0 × 10⁸ m/s
λ = unknown
ν = 1 × 10²⁰ Hz
Step 2: Substitute and Evaluate for λ
3.0 × 10⁸ m/s = λ · 1 × 10²⁰ Hz
λ = 3.0 × 10⁸ m/s ÷ 1 × 10²⁰ Hz
λ = 3.0 × 10⁻¹² m
Calculate the wavelength of a photon of light having a frequency of 3.50 x 1015 Hz. A. 1.05 x 1024 m B. 1.33 x 1016 m C. 8.57 x 10-8m D. 1.17 x 107 m

Explanation:
Since we know that

then can establish the following relationships:

What is a noble gas ?Any gas from the group of rare gases that include helium, neon, argon, krypton, xenon, and usually radon and that exhibit great stability and extremely low reaction rates. — called also inert gas.
They have properties tending to an ideal gas.
It is asked that what volume will be occupied by 0.34 moles Helium Gas
The ideal gas equation is written as
PV = nRT
At STP , T = 273 K
P= 1atm
R = 0.0821 L(atm) mol⁻¹K⁻¹
Substituting the values
1 * V = 0.34 * 0.0821 * 273
V = 7.62 L
Therefore the volume occupied by 0.34 moles of Helium Gas is 7.62 L.

Which of the following is an example of the Law of Conservation of Mass?
Answer:
C.
Explanation:
The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. For example, when wood burns, the mass of the soot, ashes, and gases, equals the original mass of the charcoal and the oxygen when it first reacted. So the mass of the product equals the mass of the reactant.
Answer:
C, since matter cannot be created or destroyed the same number of particles must be present on both sides of the equation. Hence why all chemical reactions must be balanced.
