A) Compare their sizes.
B) Compare their shapes.
C) Compare their masses.
D) Compare their colors.

Answer:

I’m pretty sure it would be the sinus cavity

Explanation:

They are located on the sides of your nose and they help filter and add moisture to any air that is inhaled

The structure contains cells that attach to the molecules we breathe in

d)sinus cavity

The sinuses are part of the nose and respiratory system , they connect to your nasal passage in a complex network of air flow and drainage passages

The structure contains cells that attach to the molecules we breathe in

d)sinus cavity

As we breath in air through our nose and mouth , it moves through sinus passage .  The sinus also produce mucus that coats and lubricate the nasal passages and the sinuses themselves

The net force which has to be applied on the arrow of 0.07kg to accelerate at the rate of 4000m/s² is 280N. Thus, the correct option is A.

A force is an influence which can be a push or a pull that can change the motion of an object. A force can cause an object with some mass to change the velocity, i.e., results into acceleration. A force is a vector quantity as it has both the magnitude and direction.

Force applied on an object can be calculated by the formula:

f = m × a

where, f = force applied,

m = mass of the object,

a = acceleration of the object

Therefore, the force applied on the arrow is:

f = m × a

m = 0.07kg

a = 4000m/s²

f = 0.07 × 4000

f = 280N

Therefore, the correct option is A.

The relationship between the evolution of marsupials and the movement of earths tectonic plate is that the marsupials migrated to different continents during the drift.

Evolution is defined as the gradual and cumulative processes by which the traits of biological population and the diversities changed over time.

Here,

The movement of tectonic plates of earth resulted in the continents to break apart into various isolated parts. During this movement of the tectonic plates, the group of organisms that were living at some continents got split from the actual habitats and were driven to different isolated community of organisms.

As a result, the marsupials who were inbreeding within their habitats were reproductively isolated to different parts of the earth. Thus they got adapted to the new areas and resulted in the creation of new species which is called the evolution of marsupials.

Hence,

The relationship between the evolution of marsupials and the movement of earths tectonic plate is that the marsupials migrated to different continents during the drift.

Answer:dew is formed on grass

Explanation:Dew forms when the object, such as the glass, cools down to the dew point temperature. Water molecules in the air continually bombard surfaces, like blades of grass. ... If the object gets cold enough, and there is enough moisture in the air, condensation is much greater than evaporation and the film grows into dew drops.

Answer:

Hope the answer helps you!!

Have A nice day!!

Pls mark as Brainliest

Explanation:

Dew forms when the object, such as the glass, cools down to the dew point temperature. Water molecules in the air continually bombard surfaces, like blades of grass. ... If the object gets cold enough, and the air contains enough moisture, condensation exceeds evaporation, and the film grows into dew drops

As fall begins, we have lots of mornings with dew on the grass. To explain this, we start with the fact that air contains water in the gas phase, called water vapor. Dew is made of liquid water that has condensed from that water vapor.

Dew occurs when objects cool, such as when drops of liquid form on the outside of an ice-cold drink glass. Dew forms when the object, such as the glass, cools down to the dew point temperature.

Water molecules in the air continually bombard surfaces, like blades of grass. Some of the molecules stick, forming a very thin film of water. This film may not last long, as the water is also evaporating. The evaporation rate depends on the water temperature, which equals the temperature on the grass.

So condensation depends on the state of the atmosphere (primarily temperature and moisture), while evaporation depends on the temperature of the object. If the object gets cold enough, and the air contains enough moisture, condensation exceeds evaporation, and the film grows into dew drops.

Each night the weather report includes the temperature and the dew point temperature. If the two temperatures are close, dew is likely during the night. Because wind and cloudy skies keep the ground from cooling, dew also tends to form on calm nights with clear skies.

Five kingdoms & Seven levels

Explanation:

Robert H. Whittaker proposed five kingdom classical system for living organisms in 1969. These were: Kingdom Monera, Kingdom Protista, Kingdom Fungi, Kingdom Animalia, and Kingdom Plantae. His work was the improvement of earlier work conducted by Carl Linnaeus who proposed three kingdom classification system (Animalia, Plantae, and Protista).

Whittaker's system further categorized each kingdom to seven levels. These were: Kingdom → Phylum  →  Class  →   Order  →   Family →   Genus  →   Species. This categorization was based on similarities in organisms at different levels.

PS: The scientific name of each organism is the combination of genus and family name.

Americium-241  isotope would be expected to have the longest half-life. Hence, option (D) is correct.

In radioactivity, the half-life is the time required for one-half of a radioactive sample's atomic nuclei to decay (change spontaneously into other nuclear species by emitting particles and energy), or, equivalently, the time required for the number of disintegrations per second of a radioactive material to decrease by one-half.

According to given data:

Rate of decay is the highest for Mercury-194, hence, its half-life is least. Then rate of decay is lowest for  Americium-241, hence, its half-life is the longest. Hence, option (D) is correct.

The order of half-life according to the data is:

Americium-241 > Silver-108 > Californium-249 >  Mercury-194.

The particle model of matter is one of the most useful scientific models because it describes matter in all three states. Understanding how the particles of matter behave is vital if we hope to understand science!

The model also helps us to understand what happens to the particles when matter changes from one state to another.

Answer:

The answer is A

Explanation:

Velocity is the rate of change of its position with respect to a frame of reference, and is a function of time.

Answer:

Its acceleration is 30 mph.

Explanation:

The true of the ball's motion will be that the velocity is 90 mph to the west. Velocity is the vector quantity. Because it shows the direction.

Acceleration is defined as the rate of change of the velocity of the body. Its unit is m/sec². It is a vector quantity. It requires both magnitudes and direction to define.

The given data in the problem is

The velocity of  baseball is,V=  90 mph

The distance travelled in mile is; d=0.0113636 mile

The time period is obtained as;

[tex]\rm t = \frac{d}{v} \\\\ \rm t = \frac{0.0113636}{90} \\\\ t=1.2 \times 10^{-4} \ hr[/tex]

The acceleration is obtained is 0.00108 mile/hr².

Hence, the true of the ball's motion will be that the velocity is 90 mph to the west.
