Answer:

Let’s get back to simple physics and the laws of motion. Your car and everything in it are traveling in a given direction, to stop in requires force be applied in the opposite direction over a period of time. This occurs extremely quickly in an accident and the force is greater because the time the opposing force is acting on the vehicle is very short. The airbag system is designed to offer you protection from the violent forces exerted on you during an accident.

There are three main components to your airbag system, the bag, the inflator and the sensor. The sensor must register a collision force roughly equal to hitting a brick wall at 10 to 15 mile per hour before it will trigger the airbag inflation. Once tripped the airbag system inflates through a chemical reaction between sodium azide (NaN3) and potassium nitrate (KNO3) which creates nitrogen gas. An igniter is set off which quickly burns the chemical fuel and creates the gas needed for expansion. The bag then blows out of its storage in a split-second. Immediately after inflation, when the chemical burn is complete, the airbag begins to deflate as the gasses escape from holes in the fabric.

Explanation:

Environmental changes affect animals depending on their ability to adapt to new conditions.

An adaptation is any type of phenotypic feature associated with a higher fitness in a particular environment.

Adaptations are features that allow organisms to adapt to challenging environmental conditions.

In conclusion, environmental changes affect animals depending on their ability to adapt to new conditions.

Answer:

A) Bacteria is essential to making nitrogen usable.

B) Denitrification returns nitrogen to the atmosphere.

D) Fertilizers containing nitrogen are carried in runoff to lakes and rivers.

Explanation:

The nitrogen cycle is the biogeochemical cycle by which nitrogen is converted into multiple chemical forms as it circulates among atmosphere, terrestrial, and marine ecosystems. Thus option A, B and D.

Nitrogen cycle is defined as a biogeochemical process that converts inert nitrogen in the atmosphere into a form that living organisms can use.

It can also be defined as a cyclical process in which nitrogen travels through both living and nonliving things,

There are seven steps of nitrogen cycle.

Biogeochemical cycle is defined as the process by which a chemical substance cycles through Earth's biotic and abiotic compartments.

Thus, the nitrogen cycle is the biogeochemical cycle by which nitrogen is converted into multiple chemical forms as it circulates among atmosphere, terrestrial, and marine ecosystems. Thus option A, B and D.

Explanation:

The proton number has the highest value in the ion

In an atomic element Q, the mass number is the number of the proton and the neutron, the electron encircles around the nucleus of the atomic element.

Recall that:

∴

The atomic element Q+ has a positively charged ion, Thus, the proton number in the mass of the atomic element Q, therefore, has the highest value in the ion.

Explanation:

Answer:(1)The urinary system's function is to filter blood and create urine as a waste by-product.

(2) two kidneys we have.

(3)The kidneys act as very efficient filters for ridding the body of waste and toxic substances, and returning vitamins, amino acids, glucose, hormones and other vital substances.

(4)Two ureters. These narrow tubes carry urine from the kidneys to the bladder. Muscles in the ureter walls continually tighten and relax forcing urine downward, away from the kidneys.

(5)A hollow, muscular, balloon-shaped organ that expands as it fills with urine.

(6)The urethra is the vessel responsible for transporting urine from the bladder to an external opening in the perineum.

(7)Urine is formed in the kidneys through a filtration of blood. The urine is then passed through the ureters to the bladder, where it is stored. During urination, the urine is passed from the bladder through the urethra to the outside of the body.

Precipitation.

Humidity is the amount of water vapour in the air. This is produced by the evaporation

of water from oceans, lakes, rivers, wetlands and plants.

When water evapour in the air cools, it condenses. In other words, it becomes liquid and

forms little drops. These droplets form clouds.

When the droplets are small, they remain suspended in the atmosphere. But they often

become colder and their size and weight increases When they become too heavy to

remain suspended in the air, they fall to the Earth’s surface. We call this precipitation,

which may be rain, snow or hail.

Factors affecting precipitation.

Different areas of the Earth’s surface receive different amounts of precipitation.

 Latitude: it rain more in the areas near the equator than in the temperature

zones and polar regions. The temperature is higher near the Equator so there is

more evaporation.

 Altitude: it rains more in high areas than in low areas.

 Level of humidity: it rains more on the coast than inland. Seas are a source of

humidity.

Precipitation is measured in millimeters (mm) per square matre.
