4. Yes! Mutations are often a random process. We cannot determine whether or not someone will be born with or without a mutation.

Answer:

DNA is a self replicated material that is inside almost every living animal, and human being. DNA contains genetic codes. Dna holds genes, for example those who created you, there genes are passed on to you causing it to also be in ur DNA. It contains instructions that an organism needs to live, develope and reproduce. DNA serves as the primary unit of heredity in different types of organisms. (It might not be long enough but maybe this could atleast be used as half a paragraph)

Answer:

if the foliation on a rock is running north-south, the pressure might be vertical (for instance, up to down)

Explanation:

The pressure is the second most principal factor that influences metamorphic rocks. It originates from the weight of the own materials, their densities, and the deepness.  

Litostatic pressure originates from the weight of materials in the interior of the crust.

Pressure generates alignment of materials (foliation and schistosity) and mineral rotation.

There are different types of metamorphism.

Dynamic metamorphism is the one where pressure is the principal factor. It generates by tectonic conditions, and it presents mainly in failure or fracture areas. It provokes trituration and recrystallization of minerals.

Classification of the metamorphic rocks according to their structure:

Foliation refers to dynamic metamorphism, where pressures act and minerals orientate perpendicular to the pressure direction.

According to this concept, if the foliation on a rock is running north-south, the pressure might be vertical (for instance, up to down) while minerals' weight helping in the process of foliation.

If the foliation on a rock is running north-south, the tectonic pressure is coming from a vertical direction.

Foliation on a rock means continuous multi layering on a metamorphic rock.

These layers can be thin as a sheet of paper.

Foliation occurs when the plain or elongated minerals inside a rock are pressed together and aligned.

Thus, If the foliation on a rock is running north-south, the tectonic pressure is coming from a vertical direction.

Answer:

Cellular respiration describes the series of steps that cells use to break down sugar and other  chemicals to get the energy we need to function.  Energy is stored in the bonds of glucose (like a stretched rubber band), and when glucose is broken down, much of that energy is released.  Some of it is captured in a form that can be used to do work in cells - a molecule called adenosine triphosphate or ATP. The energy that is not captured in ATP is usually given off as heat (one of the things that helps us maintain our normal body temperature).

Hello, 3Coli Here!

Here are your answers:

1. What is a stimulus?

Stimulus is a natural body reaction caused by changes in the environment around or inside the organism. This is a response from the brain.

2. Why does the body respond to stimuli?

The body responds to stimuli, because it needs to protect itself.

3. What are some different types of stimuli?

The two main types of stimuli are external stimuli and internal stimuli. External stimuli are reactions triggered by changes that occur outside of the body, while internal stimuli are reactions triggered by changes inside of the body.

4. What are sensory organs and what type of stimuli do these receptors respond to?

The most commonly used sensory organs include Eyes, Ears, Tongue, Nose, and Skin. Eyes respond to light and motion, because they are used to see. Ears respond to sound, because they hear. The tongue is used to taste, so it senses flavors. The nose is used to smell, so it responds to scents. Finally, the skin is used to feel, so it responds to whatever it feels.  

5. What is an explanation of how the information from stimuli is communicated to the brain?

Neuron receptors convert internal and external environments into electrical signals, and then is sent to the brain through nerves.  

6. What is a description of the two things that can happen when the brain processes the information from stimuli?

After the brain receives the signal, it will provide a response. One type of response is that the body will physically react to the change. The second type of response is to avoid the change.

Hopefully, this helps! :D

Explanation:

Sound waves propagate from the sound source. The sound through radio comes through the electrical signal, radio wave, and sound wave. Thus, option D is correct.

A sound wave is an acoustic wave that travels through a medium through the disturbance of the particles in a longitudinal direction. A few examples are radio, whisper, rustling, etc.  

The sound waves in radio first get converted into the electrical signal that passes through the circuit of the radio that further gets transferred as radio waves.

These radio waves are the part of the electromagnetic spectrum that travels at a little less speed than light. The radio waves again get converted into sound waves as it leaves the system and reaches the ear of the organism.

Therefore, option D. sound wave → electrical signal → radio wave → sound wave is the correct order.

Explanation:

It was designed to determine whether the genetic material of the bacteriophage (a type of virus that infects bacteria) is made of DNA or protein.

The Hershey-Chase experiment, also known as the "Blender Experiment," was a classic experiment in molecular biology that was conducted in 1952 by Alfred Hershey and Martha Chase. It was designed to determine whether the genetic material of the bacteriophage (a type of virus that infects bacteria) is made of DNA or protein.

In the experiment, components of the bacteriophage were labeled with radioactive isotopes of sulfur and phosphorus. The labeled phages were then used to infect bacterial cells, and the cells were subjected to various treatments to separate the viral components from the bacterial components.

The results of the experiment showed that the genetic material of the bacteriophage was made of DNA, not protein. This was determined by the fact that the labeled DNA, but not the labeled protein, was able to enter the bacterial cells and infect them. This experiment provided strong evidence for the "central dogma" of molecular biology, which states that genetic information flows from DNA to protein, but not the other way around.

Drag

Explanation:

Drag is a force caused by air that slows objects down

Friction is a major force that slows the object down, air resistance is a type of frictional force.

Air resistance is a kind of frictional force that slows down an object from moving in a particular direction.

During the movement an object has a particular speed for movement, speed depends on how friction works, more friction slows the speed of an object a low friction allows the object to at a particular speed.

Air is a mixture of gases and particles in the atmosphere, these particles create a force during the movement of an object in the air, and these forces decide the actual speed of object movement.

Therefore air resistance is a force that slows the object.
