Explanation:

Investigators can investigate the eye witness, asking questions about what the criminal looked like. They can also go off of footprints is the criminal tracked anything and try to find the shoe size to identify the criminal even further. Investigators can also locate the person if they left behind any DNA such as hair or anything that has their fingerprints on it.

Smooth hair is dominant in horses, and curly hair is recessive. Black hair is dominant, and chestnut hair is recessive. If S denotes smooth and s denotes curly, B denotes black and b denotes chestnut, classify the alleles according to their types.
SS BB bb Ss Bb ss

Answers

SS + BB = dominant
Ss + Bb = heterozygous
bb + ss = recessive
both lowercase represents a recessive gene, for example if the horse has ss it’s hair would be curly
if it has Ss while it’s hair would be straight there still could’ve been a possibility for curly hair which is why it’s heterozygous
and SS is dominantly straight hair with no chance of curly making it a dominant.

Explanation:

Hope this helped Mark BRAINLEST!!

Answer:

I'm not 100% sure

Explanation:

Different regions have access to different renewable or nonrenewable natural resources such as freshwater, fossil fuels, fertile soil, or timber based on their geographic location and past geologic processes. Access, or the lack thereof, contributes to a place’s economic development, political relationships, and culture. For example, the Great Plains region of the United States is known for its abundance of fertile soil. As a result, its main industry is agriculture. Corn, soybeans, and wheat are globally exported from this region and serve as the main economy. On the other side of the spectrum, the desert southwestern region of the United States depends on the Central Arizona Project canals to transport water from the Colorado River in order to support agriculture and urban areas. Arizona’s right to use water from this river stems from the Colorado Compact, an agreement established in 1922.

Which statement best describes the human respiratory system? A) It is composed of a network of moist passageways that permit air to flow from the external environment to the lungs. B) Each cell of the human body is in direct contact with the external environment, and gas exchange occurs by diffusion. C) The external body surface is kept moist to allow for gas exchange. D) Gases diffuse across membranes on both the external and internal surfaces of the body.

Answers

Answer:

A) It is composed of a network of moist passageways that permit air to flow from the external environment to the lungs.

Explanation:

The correct statement that describes the RESPIRATORY SYSTEM of human being is option A which states that, It is composed of a network of moist passageways that permit air to flow from the external environment to the lungs.

The sequence of processes leading to the release of energy in living cells is called respiration. The most complex respiratory system is found in mammals ( human beings). This involves the following:

the intake and absorption of oxygen from the surrounding environment; the transport of oxygen to the individual cells in the body; andusing oxygen to release energy (as Adenosine triphosphate) from energy-rich substances.

Because human beings are exposed to the atmosphere and have dry body coverings. Gaseous exchange cannot occur through their body surfaces, instead they possess respiratory structures to being dry air in contact with moist surfaces within their bodies. These structures includes:

the trachea andthe lungs ( where bronchi and alveoli are located)

TRACHEA or the wind pipe channels the air to the lungs. At the thorax, the trachea into two forming the right and left BRONCHI.

The alveoli is where the gaseous exchange takes place. Tiny blood vessels, called capillaries, are closely wrapped around the outside of the alveoli. This enables oxygen to diffuse across the walls of the alveoli into the blood.

Therefore the correct option that describes the RESPIRATORY SYSTEM of human being is A which states that It is composed of a network of moist passageways that permit air to flow from the external environment to the lungs.

Option B is WRONG because human beings are not unicellular organisms like Amoeba where their gaseous exchange organs are cell membrane or body surfaces.

Option C and D are equally wrong because human beings are not simple animals like amphibians that involves in cutaneous (skin) respiration.

Please help! Questions in the picture, giving brainiest to the best answer!

Answers

Answer:

This makes them move faster and further apart and the substance expands. This makes the object's volume increase which changes causes the density to decrease.

When a substance is cooled, the particles lose energy. This makes them move slower and closer together and the substance contracts. This makes the object's volume decrease which changes causes the density to increase.

Explanation:

When an object is heating up its molecules will move faster and expand the object, this means the volume is increasing. Density is equal to mass over volume meaning if the volume is increasing the density will decrease. The opposite is true for when the substance is cooled. Molecules will move slower and the object will contract. The volume will decrease and the density will increase.

What is the dewpoint if the dry-bulb temperature is 18 degrees C and the relative humidity is 64%?

Answers

Answer and Explanation:

I think the dewpoint is 11.09°C or 11.1°C. I'm not sure though..

let me know if I'm wrong..

The dew point temperature is at 11.62°C for a relative humidity of 64%

Dew point

The dew point is the temperature the air needs to be cooled to (at constant pressure)

Given that:

Relative humidity (R) = 64%, Dry-bulb temperature(T) = 18 °C.

[tex]B=\frac{ln(\frac{R}{100} )+\frac{17.27*T}{237.3+T} }{17.27} =\frac{ln(\frac{64}{100} )+\frac{17.27*18}{237.3+18} }{17.27} =0.0447[/tex]

The dew point (D) is:

[tex]D=\frac{237.3*B}{1-B} =\frac{237.4*0.0467}{1-0.0467} =11.62[/tex]

The dew point temperature is at 11.62°C for a relative humidity of 64%
