Which of the following is not a key ingredient in cloud formation?
particles. drizzle. water vaper. drop in air pressure

Answers

Answer:Drizzle

Explanation:

Clouds require water vapor, particles the vapor can condense around, and a drop in air pressure to form.

Cloud formation is a process that begins with a drop in air pressure. An ingredient that is not key in the formation of clouds is;

A. Drizzle

Drizzle is not an important factor in the formation of clouds. Clouds are formed when water and ice are suspended in the air.

The process of cloud formation begins when the terrain is heated up by the sun.

Wind blows more around the areas of low pressure thus causing the rising of warm air which holds up water.

After some time, this air becomes condensed and falls down as rain.

Summarily, Drizzling is not an important part of cloud formation.

A famous celebrity has an extreme security system for their estate. The security system includes sensors in the ground as well as on the sides of the buildings. A loud truck drives down the road entering the estate. There is a sensor in the ground and another on the side of the security guard’s shed. If both sensors are 100m from the truck, which sensor will pick up the noise of the truck first and why?

A.
Guard Shed - The sensor on the security guard’s shed will detect the sound first because the sound is traveling through the air and sound will travel fastest through a gas.

B.
Ground - The sensor in the ground will detect the sound first because the sound is traveling through the dirt and sound will travel fastest through a solid.

C.
Same time - Because the sound is traveling through both the ground and the air at the same time, it will reach both the shed and the ground sensor at the same time.

D.
Neither sensor - 100m is too far for the sound to travel. Neither sensor will pick up the sound of the truck until it is closer to them.

Answers

Answer:

B. Ground - The sensor in the ground will detect the sound first because the sound is traveling through the dirt and sound will travel fastest through a solid.

Explanation:

Sound wave is an example of mechanical wave, which means sound waves require a medium to travel through. However, how fast a sound travels is dependent on the kind of medium it travels through. Sound travels fastest via a SOLID medium, then liquid and slowest through gases.

According to this question, sensor in the ground and side of the security guard’s shed were placed in an estate owned by a famous celebrity. A loud truck, then, drives down the road entering the estate.

Based on the principles of sound eaves movement, the sound from the truck will be picked by the sensors in the GROUND first because the sound is traveling through the dirt and sound will travel fastest through a solid.

A. receives messages sent by the control center
B. carries out a response to restore internal
conditions
C. detects stimuli and sends information to the
control center
D. compares current conditions with ideal values
for those conditions

Answers

Answer:

b

Explanation:

Homeostasis has been the tendency of the organism to maintain the equilibrium state. The stimuli are detected and transmitted to the control center by the receptors. Thus, option C is correct.

What is homeostasis?

Homeostasis is the physiological process that monitors the internal environment of the body. This involves the feedback system that includes receptors that report and transfers the information to the control center of the body.

The receptor is involved in detecting the stimuli in order to generate the response through the feedback control system. The mechanism involves the effector that provides a response to the stimuli detected and transmitted by the receptors.

Therefore, in option C. the receptor sends information by detecting the stimuli.

Write a summary of the digestive system. Include the organs of the system and tell if physical or chemical change or both take place in each organ.

Answers

The human body uses the process of digestion to break down food into a form that can be absorbed and used for fuel. The organs of the digestive system are the mouth, esophagus, stomach, pancreas, liver, gallbladder, small intestine, large intestine and anus. Recognizing how these organs work together to digest food is key to understanding how digestion works.

The digestive process begins in the mouth. Even before eating begins, the anticipation of eating stimulates glands in the mouth to produce saliva. The digestive system carries out three primary processes: mixing food, moving food through the digestive tract (peristalsis) and using chemicals to break down food into smaller molecules.

which organelle packages proteins in vesicles and sends them to the body where they are needed.

Answers

Answer- The Golgi apparatus gathers simple molecules and combines them to make molecules that are more complex. It then takes those big molecules, packages them in vesicles, and either stores them for later use or sends them out of the cell. It is also the organelle that builds lysosomes (cell digestion machines).

Earth began as a mixture of about 90% stony, olivine-rich material and about 10% iron metal, just like the composition of chondritic meteorites. Soon after its formation the interior of the Earth is thought to have become very hot. What was the result of this increase in heat? A) The iron melted and collected in the interior of Earth to become its core. B) The olivine remained behind, becoming the mantle and the melted iron became the core. C) Both the olivine and iron melted and as they later solidified, became the mantle and the core. D) The olivine became the crust and the iron, melting, defended into the earth to become the core.

Answers

Answer: D. The olivine became the crust and the Iron melting defended the earth to become the core.

Explanation:

Earth was formed after it has went through a molten stage that led to the heavy materials sure as Iron metal moving inward to form the core, and the light materials moves toward the surface to form the crust.

The heat for the melting came from meteorite impacts which is usually very hot, the moon's impact, and the decay of radioactive elements.

Geological activity on the earth is driven from this initial source of heat at the earth's formation until now.

D is the answer

Explanation:

A composite is made by combining two or more other materials so they improve one another but keep distinct and separate identities in the final product. So a composite isn't a compound (where atoms or molecules bind together chemically to make something quite different), a mixture (where one material is blended into another), or a solution.

15. Briefly explain how the gel (or DNA fingerprint) is made after DNA has been amplified.

Answers

Answer:

Like the fingerprints that came into use by detectives and police labs during the 1930s, each person has a unique DNA fingerprint. Unlike a conventional fingerprint that occurs only on the fingertips and can be altered by surgery, a DNA fingerprint is the same for every cell, tissue, and organ of a person. It cannot be altered by any known treatment. Consequently, DNA fingerprinting is rapidly becoming the primary method for identifying and distinguishing among individual human beings. DNA fingerprints are also useful in several applications of human health care research and for diagnosis of inherited disorders. DNA fingerprinting is often used in the justice system to link suspects to biological evidence and solve paternity cases.

Explanation:

DNA sample: A DNA sample that will be examined must first be gathered. DNA extraction: Using the lysis process, DNA is then extracted from the sample.

What is DNA fingerprint?

Restrictions endonucleases:The DNA fragment is cut at a particular place by a specific restriction enzyme.

Alec Jeffrey, a British biologist, created the DNA fingerprinting technique in 1984 after noticing that some highly variable DNA sequences, or minisatellites, that are repeated inside genes but do not affect their activities.

In DNA fingerprinting, a gel-like fluid is used to distinguish between DNA molecules that move at various speeds. A DNA molecule that is huge moves slowly, whereas a DNA molecule that is little moves quickly.

Therefore, DNA molecules are divided in gel electrophoresis according to size. When DNA molecules are divided into distinct sizes, bands of DNA are created.
