Answer:
Cockroach is you answer.
Explanation:
They do this by using a very efficient breathing system that uses air filled tubes, called trachea, to deliver oxygen directly to cells. Oxygen flows in as required into the tracheal system through valves on the insect, called spiracles. But, sometimes, they shut their spiracles and stop breathing.

What are the parts of the compound light microscope
: The three basic, structural components of a compound microscope are the head, base and arm.
•Head/Body houses the optical parts in the upper part of the microscope.
•Base of the microscope supports the microscope and houses the illuminator.
•Arm connects to the base and supports the microscope head.
The head, base, and arm are the three fundamental structural elements of a compound microscope.
Thus, Head/Body houses the optical components in the microscope's upper section. The base of the microscope holds the illuminator and supports the microscope.
Arm supports the microscope head and is attached to the base. The development of the field of microbiology brought into focus the significance of the identification, seeing, observation, and comprehension of microbes, including their structural morphologies and mechanisms.
The study of tiny creatures and agents that can only be seen and investigated under a microscope falls under the purview of microbiology.
Thus, The head, base, and arm are the three fundamental structural elements of a compound microscope.

Which of the following best describes the motion of the object in this p-t graph
Answer:
I think its the third one should be
Answer:
The graph above shows that the position of the body is changing with time exponentially and it is accelerating. The velocity of the body is changing with time and as a result the distance it is covering per time will be changing. Generally the graph of positions against time for a body that is accelerating will always look like the diagram above. For constant velocity motion, the graph will be a straight line with slope equal to the velocity of the body.
Explanation:
The velocity - time graph will for a undergoing the motion described by this graphics will be a straight line graph with it slope equal to the acceleration of the body.
What evidence did Mendel find that supported his law of independent assortment?
A. Some traits are controlled by several different genes.
B. Most traits have a dominant form and a recessive form.
C. A trait can be passed on from a parent to an offspring.
D. Different traits are passed on independently of each other.
Answer:
D
Explanation:
The evidence observed by Mendel supporting his law of independent assortment is that different traits are passed on independently of each other (Option D).
What is independent assortment?In genetics, independent assortment refers to the independent segregation of characters (genes) in offspring.
Independent assortment can be observed by crossing parental lines that exhibit different traits.In conclusion, the evidence observed by Mendel supporting his law of independent assortment is that different traits are passed on independently of each other (Option D).

State two functions of proteins
Answer:
Protein has many roles in your body. It helps repair and build your body's tissues, allows metabolic reactions to take place and coordinates bodily functions. In addition to providing your body with a structural framework, proteins also maintain proper pH and fluid balance. Your body needs protein for growth and maintenance of tissues. Some proteins are hormones, which are chemical messengers that aid communication between your cells, tissues and organs.

Which of the following is true:
- Since the active site has a specific shape it can only fit one substrate.
- The active site can fit any type of substrate.
- Nothing can fit or bond with the active site of an enzyme.
Answer: Since the active site has a specific shape it can only fit one substrate.
Explanation: I took one for the team on Ed puzzle.
Since the active site has a specific shape it can only fit one substrate. The correct option is A.
What is active site of enzyme?The active site is the region of an enzyme where substrate molecules bind and undergo a chemical reaction in biology and biochemistry.
The active site is made up of amino acid residues that form temporary bonds with the substrate (binding site) and residues that catalyze the substrate's reaction (catalytic site).
The active site of an enzyme is the specific region of the enzyme where a substrate binds and catalysis or chemical reaction occurs.
It is a protein structural element that determines whether the protein is functional when subjected to an enzyme reaction.
A holoenzyme is a fully active enzyme that is made up of a protein portion (apoenzyme) and a cofactor.
Thus, the correct option is A.

There is an enzyme in your stomach. Explain how the enzyme would be affected if it was moved
the small intestines.
Answer:
It might not work as efficiently because the conditions are different
Explanation:
The stomach is highly acidic compared to the small intestine. That means the pH is higher in the small intestine. Stomach enzymes are adapted to work at low pH, but might not work at a higher pH as in the small intestine. They might not be able to efficiently catalyze reactions in the small intestine.

Which information can be determined from the chemical formula?
Answer:
The number of atoms of each element in a glucose molecule
The information that can be determined from the given formula is the number of atoms of each element in a glucose molecule. The correct option is D.
What is an element?Any substance that cannot be decomposed into simpler substances by ordinary chemical processes is referred to as a chemical element. Elements are the fundamental building blocks of all matter.
An element is a pure substance that cannot be broken down into simpler substances through physical or chemical means.
An element is composed of the same type of atoms. Metals, nonmetals, and metalloids are the three types of elements. The symbols for the elements are used to represent them.
Glucose is made up of three elements: carbon, hydrogen, and oxygen. 6 carbon atoms bonded together in a chain with oxygen and hydrogen atoms.
The formula for the glucose can be illustrated as [tex]C_6H_1_2O_6[/tex]

Small insects can walk across the surface of calm water.
Their feet push the surface of the water down slightly,
somewhat like a person walking across a trampoline, but
they do not break the surface. What is the best
explanation for why this happens?
A. The insects are light enough so that they do not break the hydrogen bonds holding the water molecules
B. The insects actually use their wings to hover slightly above the waters surface and they only skim it with their feet
C. The insects feet are non- polar so they are repelled by the polar water molecules and are pushed away from the waters surface
D. The insects are small enough to see the individual water molecules so they are able to step carefully from one molecule to the next
Answer:
A. Insects are light enough so that they do not break the h bonds holding the water molecules together
Explanation:
The insects are light enough so that they do not break the hydrogen bonds holding the water molecules when they walk across the surface of calm water their feet push the surface of the water down slightly and it is due to surface tension.Thus, option A is correct.
What is surface tension?Surface tension is the tendency of liquid surfaces at rest to shrink into the minimum surface area possible.
Surface tension is responsible for the shape of liquid droplets and the surface tension of water is about 72 mN/m at room temperature.
Water has a tremendous amount of surface tension due to which small mass distributed effectively on its surface.
Surface tension is represented by the symbol T.
Therefore,the insects are light enough so that they do not break the hydrogen bonds holding the water molecules when they walk across the surface of calm water their feet push the surface of the water down slightly and it is due to surface tension.Thus, option A is correct.
