Muscular System: It comprises of muscles that permit movement of the body, maintains posture and circulates blood throughout the body. So, MUSCLES are attached to bones and help them MOVE.
Circulatory System: Is system that permits blood to circulate and transport nutrients, oxygen, carbon dioxide, hormones, and blood cells to and from the cells in the body to provide nourishment to the body. So, BONE MARROW inside the bones produce the cells inside your BLOOD.
Nervous System: It is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body. So, the BRAIN tells the skeletal system when and where to move. Bones protect the ORGANS.
Digestive System: It consists of the central gastrointestinal (GI) tract and its associated accessory organs that break down food into smaller components so that nutrients can be absorbed and assimilated. So, CALCIUM help to grow and repair bones. SKELETAL SYSTEM protect the organs.
Answer:
It is a eukaryotic cell because prokaryotes don't have a nucleus, rather, they have a nucleoid.
The mass of the ethylene glycol used is 14.26 g
<h3>What is the freezing point?</h3>
The freezing point is the temperature at which a liquid is converted to a solid.
Given that;
ΔT = 0.0°C - ( -4.3°C) = 4.3°C
ΔT = 4.3°C
But we know that
ΔT = k m i
m = ΔT/k i
m = 4.3°C/1.86 °C/m * 1
m = 2.3 m
Now;
Let the mass of ethylene glycol be m
Molar mass of ethylene glycol = 62 g/mol
Mass of solvent = 100.0 g or 0.1 Kg
Then;
2.3= m/62/0.1
2.3 = m/62 * 0.1
m = 2.3 * 62 * 0.1
m = 14.26 g

DNA SEQUENCING is a biochemical process used for determining the order of the nucleotide bases, adenine, guanine, cytosine, and thymine, in any DNA molecule. By comparing the DNA sequence of two organisms, scientists can see if the organisms are related or not, as well as how closely they are related.
Answer:
Final temperature = 22.21 °C
Explanation:
Heat gain by ethanol = Heat lost by water
Thus,
Where, negative sign signifies heat loss
Or,
<u>For ethanol:
</u>
Density = 0.789 g/mL
Volume = 55.0 mL
Considering the expression for density as:
So,
So, Mass= Density*Volume = 0.789 g/mL * 55.0 mL = 43.395 g
Initial temperature = 9.0 °C
Specific heat of ethanol = 2.57 J/g°C
<u>For water:
</u>
Density = 1.0 g/mL
Volume = 55.0 mL
Considering the expression for density as:
So,
So, Mass= Density*Volume = 1.0 g/mL * 55.0 mL = 55.0 g
Initial temperature = 28.6 °C
Specific heat of water = 0.450 J/g°C
So,
<u>Final temperature = 22.21 °C </u>
