Heart disease affects the cardiovascular system by plaque building up on the artery walls narrowing them making it harder for blood to flow through which could lead to heart attack or probably stroke if the plaque blocks it entirely or maybe almost entirely.
Heart disease may also affect our nervous system for there is higher risk to stroke and it is due to limited flow of blood to the brain and may lead to heart failure which may happen with heart disease that puts the stress on the brain and nerves.
The digestive system is affected by heart disease that causes the system to not get the right amount of oxygen and the nutrients that it needs from the blood.
Answer: The correct answer is black because the product of its side and mass is lower.
Explanation: Density of a substance is defined as the mount of matter that can be stored in a given volume.
Mathematically,

As, density is inversely proportional to the volume of the substance.
The substance will be more denser if it has less volume and it will be less denser if the volume is more.
We are given two cubes having different sides.
Volume of the cube is calculated by using the formula:

where, a = side of the cube.
Black: The side of this cube is 2 and volume will be =
Yellow: The side of this cube is 3 and volume will be =
As, the volume of black cube is less. So, this cube will be more denser.
Density of black cube: 
Density of Yellow Cube: 
Hence, black cube will be more denser because the product of its side and mass is lower.
The data given are
melting point density
<span>Zinc 419.53 oC 7.134
Nickel 1455oC 8.912
Copper 1084.62oC 8.96
Silver 961.78oC 10.501
Gold 1064.18oC 19.282
density is the mass per unit volume. Melting point is determined by the intermolecular forces between particles in the solids.
We </span>have been asked to find which cube weighs the most
density = mass/volume
when volume is constant for all the metals, then density is directly proportional to mass. Therefore metal with highest density has the highest mass.
from the given metals, metal with highest density is Gold.
correct answer is Gold.
Due to its cleaner combustion, natural gas is the most environmentally safe fossil fuel. Natural gas doesn't have as many toxic combustion byproducts as other fossil fuels.
- Natural gas is adaptable. Starting and stopping a gas-fired power plant is substantially faster than one that burns coal.
- Due to its flexibility, it complements renewable energy sources like solar and wind, which are only usable when the sun is out and the wind is blowing.
- When burned to produce power, natural gas is the cleanest-burning hydrocarbon, releasing about half as much carbon dioxide (CO2) and only one-tenth as much air pollutants as coal.
- By switching to natural gas from coal, there is a significant opportunity to cut CO2 emissions and air pollution in the near future.
- Because Natural gas is now so widely accessible through LNG, it can assist nations in coping with short-term supply interruptions.

Answer:
The correct answers are:
- is most commonly used;
Despite being a projection that is not the best representation, nor the most accurate one, still this map seems to be the most practical one for usage, so it is still the most popular one.
- presents longitude lines as parallel;
This projection is a cylindrical one, so all of the longitude lines are presented are lines that are parallel to one another.
- distorts land size as it moves away from the Equator;
The biggest problem with this projection is the distortion. The distortion becomes bigger and bigger with the increase in latitude, so it depicts the places around the poles as much larger than they actually are.
