9. Which of the following human body systems work together for support, protection, and movement? A. the respiratory system and cardiovascular system B. the skeletal system and muscular system C. the skeletal system and integumentary system D. the integumentary system and digestive system

Answers

Answer 1
Answer:

The Human body system that work together for support, protection and movement is ; ( B )  The skeletal system and muscular system

The skeletal system provides support for every other system present in the human body and  it also gives the organism its shape as well. while the muscular system protects the vital internal organs from external shocks.

Both Skeletal and muscular system provide movement, support and protection  for the Human body because without any of these the human body cannot make movements or support itself efficiently.

Hence we can conclude that The Human body system that work together for support, protection and movement is The skeletal system and muscular system.

During which season is the sun highest in the sky? A.
spring

B.
summer

C.
fall

D.
winter

(this is science)

Answers

Answer: B.  summer

Explanation:

Seasons occur due to tilt of the Earth. Earth's axis is tilted 23.5° from the vertical. As the Earth revolves around the Sun, sometimes the Northern hemisphere points towards the Sun and sometimes away.

When the northern hemisphere points towards the Sun, Summer occurs and in the Southern hemisphere, winter occurs. In Summers, the Sun is highest in the sky and the sun rays fall directly. The duration of day time is greatest in summers. In winters, the Sun is lowest in the sky and sun rays fall obliquely.

summer i think because thats when its warmest

Cecil is working with samples of chlorine (Cl), oxygen (O), bromine (Br), and silver (Ag). The samples are all at room temperature. Which substance is most likely the most dense?chlorine
oxygen
bromine
silver

Answers

Answer: Option (d) is the correct answer.

Explanation:

As it is known that density is the amount of mass divided by the volume.

Mathematically,     Density = (mass)/(volume)

Since, mass is directly proportional to density. Hence, more is the mass of an object more will be its density.

At room temperature chlorine exists as a gas and its molar mass is 35 g/mol.

At room temperature oxygen exists as a gas and its molar mass is 32 g/mol.

At room temperature bromine exists as a liquid and its molar mass is 80 g/mol.

At room temperature silver exists as a solid and its molar mass is 108 g/mol.

As the mass of silver is greater and it exists as a solid at room temperature. Hence, it will be most dense in nature.

Therefore, we can conclude that out of the given options silver substance is most likely the most dense.

The answer is silver. Silver is the most dense, it's a solid so it is more compact and is obviously the most likely to have more mass to it.

The force that one surface exerts on another when the two rub against each other is calledA. friction.
B. acceleration.
C. inertia.
D. gravity.

The law of universal gravitation states that any two objects in the universe that have mass, without exception,
A. attract each other.
B. repel each other.
C. combine to provide a balanced force.
D. create friction.



ANswer both

Answers

1. Friction (Example: when you rub your hands together and you start to feel heat.)

2. Attract each other. (Example: Every object has a gravitational pull of some sort. The larger the object, the stronger the gravitational pull. This is why the sun is able to keep all eight planets in orbit around it.)

A graduated cylinder is filled to an initial volume of 12.7 ml. A rock Is dropped into the graduated cylinder. The final volume of the graduated cylinder is 18.2ml. What is the Rocks volume in both ml and cm3? What method was used to determine this?

Answers

Answer:

V = 5.5 mL

Explanation:

The volume filled in the graduated cylinder is 12.7 mL

now when a stone is dropped into the cylinder then the volume of liquid is raised to final level of 18.2 mL

so as per the theory of given by Archimidies we can say that the volume of the object is exactly same as the volume displaced by the object

So here the volume displaced by the object is given as

V_(displaced) = V_f - V_i

V_(displaced) = 18.2 mL - 12.7 mL

V_(displaced) = 5.5 mL

so the volume of the object is given as

V = V_(displaced)

V = 5.5 mL

First of all, ml and cm^3 are equal. The volume of the rock is 5.5 ml. This is found by subtracting the volume of just the water from the combined volume of the rock and the water leaving you with just the volume of the rock. This is method is using water displacement.
