Answer:
The correct option is C.
repaying an oxygen debt.
Explanation:
This is because while running, humans breath shallowly which could not provide the oxygen requirement for the respiratory system and fit in for blood need.
After running, you tend to breathe heavily because your muscle work very hard , the body use more oxygen and produced more carbondioxide, therefore the lungs and respiratory system must try to provide more oxygen to the blood. sympathetic nerves stimulate respiratory muscles
so as to increase the rate at which we breathe.

What is a SNP mutation?
Answer:
Explanation:
Single nucleotide polymorphisms, frequently called SNPs (pronounced “snips”), are the most common type of genetic variation among people. Each SNP represents a difference in a single DNA building block, called a nucleotide.Most commonly, these variations are found in the DNA between genes.
single nucleotide polymorphism
A single nucleotide polymorphism, or SNP (pronounced "snip"), is a variation at a single position in a DNA sequence among individuals.
Each SNP represents a difference in a single DNA building block, called a nucleotide. For example, a SNP may replace the nucleotide cytosine (C) with the nucleotide thymine (T) in a certain stretch of DNA. Most commonly, these variations are found in the DNA between genes.

A scientist is researching two different traits in an insect: body texture and color. Smooth body (B) is dominant to bumpy body (b), and gray (G) is dominant to white (g). A BbGg and a bbgg insect mate and produce the following 480 offspring: Phenotype Number of Offspring Smooth, gray 119 Bumpy, white 117 Smooth, white 123 Bumpy, gray 121 What type of inheritance is displayed from these offspring
Answer:
Independent assortment
Explanation:
The type of inheritance displayed by the offspring is a simple independent assortment inheritance according to Mendelian law.
The result of crossing BbGg and bbgg is as follows (see the attached image)
4 BbGg smooth and gray
4 Bbgg smooth and white
4 bbGg bumpy and gray
4 bbgg bumpy and white
The phenotype ratio from the cross is 1:1:1:1 as far as the independent assortment is concerned.
Now, looking at the population of each phenotype from the cross
Smooth, gray 119
Smooth, white 123
Bumpy, gray 121
Bumpy, white 117
119:123:121:117 is approximately equal to 1:1:1:1.
Hence, the cross agrees with Mendel's law of independent assortment of genes.

Haley knows that plants and animals are made up of many different materials. She wants to know how these materials can cycle through an ecosystem.
What question could Haley ask to learn more about this topic?
A.
What kind of organism is the most popular at Haley's school?
B.
What happens to the materials that make up a living organism after it dies?
C.
What will happen to a sunflower plant if it is grown in a dark closet?
D.
What kind of plant should Haley buy her mom for her birthday
Answer:
B. What happens to the materials that make up a living organism after it dies.
Explanation:
An ecosystem can be defined as the natural living habitats of both living and non-living organisms.
Ecosystem services such as plant pollination, nutrient cycling and water purification are essential services that are being provided by the ecosystem. These services are really very vital, important and useful for the sustenance of life, both for humans, plants and animals because they enhance social welfare.
In this scenario, Haley knows that plants and animals are made up of many different materials. She wants to know how these materials can cycle through an ecosystem. Therefore, the question Haley could ask to learn more about this topic is; what happens to the materials that make up a living organism after it dies?
Basically, the material that make up a living organism decomposes after it dies and are then used up as nutrients by plants growing on the soil.

What are the reactants and products of photosynthesis? *
glucose and oxygen are the reactants; carbon dioxide and water are the products
carbon dioxide and oxygen are the reactants; glucose and water are the products
Carbon dioxide and water are the reactants, glucose and oxygen are the products
glucose and water are the reactants, carbon dioxide and oxygen are the products
Answer:
Explanation:
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
Answer:
glucose and oxygen

Why do viruses not fit easily into the broadest taxonomic category, life? (Choose all that apply)
1. They are not made of cells.
2. They have a capsid.
3. They do not reproduce on their own.
4. They do not respond to stimuli.
Answer:
viruses are not fit into broadest taxanomic system because:
they are not cells
they do not reproduce their own
they do not respond to stimuli.
Explanation:
viruses have capsid and are not cells. to be a cell they must have a cell membrane while viruses lack cell wall. they replicate by using the host machinary in which they are causing infection. they are acellular and obligate intracellular parasites of anials plants fungi and bacteria.

Who does the mesosphere share a boundary with?
Answer:
The boundaries between layers in the atmosphere have special names.
Explanation:
The mesopause is the boundary between the mesosphere and the thermosphere above it.
The stratopause is the boundary between the mesosphere and the stratosphere below it. Scientists know less about the mesosphere than about other layers of the atmosphere.

The user needs to drag the slider bar in an upwards direction in order to completely melt away a body layer when in the dissection study area.
True or False
Answer:
False
Explanation:
During the dissection study the body is kept in laying position so that the scientist can easily perform experiments. The body is kept in laying position not in upward position. The body in upward position will have gravitational effect on the fluids and the body layer will not melt.
Consider the two samples of sedimentary rock seen here.Predict which rock would be more likely to undergo physical weathering. Explain how and why.
A) Sandstone. Sandstone has more obvious layers of sediments.
B) Shale. Shale is fine grained and is more likely to dissolve in water.
C)Sandstone. Sandstone is made of large sand-like grains and is easily eroded by wind
D)Shale. Shale contains iron which is an element that easily combines with the oxygen in the atmosphere to produce rust.
Answer: A) Sandstone. Sandstone has more obvious layers of sediments.
Step by step explanation: As you take a look at the given pictures, you notice that (Sandstone) Is more closed off than (Shale). So whenever rain comes, rain will seep into the little openings of the rock shale has, causing it to break down.Same for strong wind, since shale isn't as compacted as Sandstorm, then shale will not last very long. Therefore making Sandstone being able to undergo more harsh conditions.
explain the advantage of the synaptic cleft being so small
Answer:
The size of the synaptic cleft is small which results in the neurotransmitters to pile up over time thus making the neurotransmitters' concentration increase and therefore can proceed with their function of sending nerve impulses. Hope that helped!

The graph below shows the breakdown of a protein in the human stomach without a digestive enzyme.
Answer:
B
Explanation:
Take the test
The breakdown of protein in the presence of enzyme has lower activation energy.
The breakdown of protein in the stomach is achieved with the loss of peptide bonds, and the complex is broken down into amino acids.
What is breakdown of protein?The protein is broken down in the digestion at small intestine and stomach. The graph represents the energy of the reaction with the progress of protein degradation.
The energy of the reaction is highest when the protein breakdown activation is processed. The enzyme is the catalyst, that acts in fasting the reaction with the lowering of activation energy.
Thus, the breakdown of protein in the presence of enzyme has lower activation energy.

A strong UREA solution is a common reversible denaturant. Additional treatment with 2-mercaptoethanol completely denatures proteins that contain disulfide bonds.
Denaturing reversible agents can alter the secondary/tertiary structure of a protein without altering its primary structure.Urea is a reversible denaturant that breaks hydrogen bonds in the secondary structure of proteins without modifying the primary structure.2-mercaptoethanol is a denaturing agent that cleaves disulfide bonds between cysteine residues.In conclusion, a strong UREA solution is a common reversible denaturant. Additional treatment with 2-mercaptoethanol completely denatures proteins that contain disulfide bonds.
