Answer:

Starch molecules are too large to diffuse into
cells.

Explanation:

just did it

Your body needs to break down starch into glucose because starch molecules are too large to diffuse into cells. The size of the starch molecule is too large to pass through the cell membrane and into the cell where it is needed.

Starch is a complex carbohydrate made up of many glucose molecules bonded together in a long chain. When we consume starch, our digestive system breaks it down into individual glucose molecules, which can be absorbed into the bloodstream and used by cells for energy.

The starch molecule must first be broken down into its individual glucose units, which are small enough to pass through the cell membrane and be used for energy.

So, while it is true that starch contains more energy per molecule than glucose, and glucose molecules are actually smaller than starch molecules, the primary reason why our bodies need to break down starch into glucose is because of the size of the starch molecule itself.

Answer: introns (DNA that doesn't code for protiens)

The suggested ratio for inspiration and expiration time during normal spontaneous breathing is 1:1.5 to 1:2 s with an inspiratory time of 0.8 to 1.2 s.

The inspiratory time can be calculated by dividing the tidal volume by the inspiratory flow. Thus, decreasing the VT or increasing the inspiratory flow, there is a decrease in the inspiratory time.

With this information, we can conclude that the suggested ratio for inspiration and expiration time during normal spontaneous breathing is 1:1.5 to 1:2s with an inspiratory time of 0.8 to 1.2 s. During mechanical ventilation, it will depend on the tidal volume, respiratory rate, inspiratory flow and inspiratory pause.

The Replication process in eukaryotic and prokaryotic cells is quite similar. Almost the same enzymes are involved. 1)eukaryotic, 2)multiple, 3)circular.

In prokaryotic cells,  DNA Replication consists of the unwinding and opening of the double-stranded DNA molecule, a process that starts at the replication origin.

The process is completed in three stages,

⇒ Initiation, in which helicase and topoisomerase are the first enzymes involved.

Helicase works in the replication origin.

Topoisomerase impedes the DNA double helix near the replication forks to get too coiled when the DNA is opening.

⇒ Elongation, in which DNA polymerase I and III, primase, and ligase act,

Polymerase I and III are responsible for DNA elongation.

Primase is in charge of synthesizing primers.

DNA polymerase I eliminate ARN primers and substitute them with DNA.

DNA ligase seals the gaps that remain after replacing the primers.

⇒ Mistakes correction

Endonuclease cuts the wrong segment

Polymerase I and III are in charge of correcting errors and filling empty spaces.

Ligase seals the corrected extremes.

The prokaryotic replication result is two DNA molecules, each of them carrying an old strand and a new strand.

Eukaryotic DNA replication is the process through which DNI molecule duplicates. This event takes place during the S stage of the interphase. So when the cell divides during mitosis or meiosis, each cell will get a complete set of chromosomes.

DNI replication is semi-conservative because each new molecule carries an original DNI strand and a new one. The fact that the new molecule is composed of an original strand makes it semi-conservative. The old existing strands are used to synthesize the new complementary strand.

The main difference concerning the prokaryotic replication process is that in eukaryotic cells there are

The origin of the replication requires

Once the molecule is opened, there is a region named replication forks.

DNA strands are antiparallel, and replication occurs only in 5'-3'direction. So one of the strands will replicate continuously, while the other strain will be formed by short fragments known as Okazaki fragments.

Primers are needed to make the DNA polymerase work. Primers are small units of RNA and are placed at the beginning of each new fragment. These are later eliminated by Polymerase.

Ligase seals the gaps.

Answer:

The way that light waves interact with different mediums is called the refraction.

When does reflection occur?: It occurs when light waves collide with a medium, causing the light waves to bounce off. The light reflects off the medium at a similar angle to which it initially stuck the material

Light reflects off of the medium at a 40 degree angle to which it initially struck the material. This means that if the light hits a mirror at a 40-degree angle, it will bounce off at a 40 degree angle. Draw a picture of what this looks like. (you'll have to draw the picture by yourself)

When does refraction occur?: It occurs when light travels through a transparent medium, causing them to bend and change direction. AS the light passes from air into water, it bends.

When light can pass through an object, it is called transmission.

When does absorption occur?: It occurs when light waves strike a medium and are neither reflected or refracted, nor are allowed to pass through.

Describe how visible light interacts with these materials:

• Mirror: Visible white light that is directed onto the surface of a mirror at an angle (incident) is reflected back into space by the mirror surface at another angle (reflected) that is equal to the incident angle, as presented for the action of a beam of light from a flashlight on a smooth, flat mirror.

• Glass of water: The light travels straight through the glass, but the direction it is traveling bends when entering and leaving the object.

• Dark fabric: Dark objects (fabric) absorb those wavelengths, and lighter objects reflect more. The temperature of the black fabrics shown in visible and near-infrared (shown on the left) over time.

What are some examples of matter waves?: Sound waves, waves in a Slinky, and water waves are all examples of this.

What are some examples of electromagnetic waves?: Gamma rays, light waves, wireless waves, & X-rays are examples.

How are electromagnetic waves different from matter waves?: The main difference between electromagnetic waves and matter waves is in the components that make them. Also, there is no need for sound radiation to pass through a medium/requirement to communicate with other particles to travel like waves of matter.

Would outer space be an ideal spot for a concert? Why or why not?: (you can change this depending on your opinion) No, it wouldn't. There is no oxygen up in outer space, as well as gravity to keep the people, as well as the instruments grounded. The likelyhood of floating away is very high, so, as soon as you get there you wouldn't be able to see the concert at all.

Matter waves need to interact with particles of either a solid, liquid, or gas to travel.

Record your findings of sound and light waves for each of the following.

• Traveling through air: The light waves pass thru the air more quickly than sound waves.

• Traveling through metal: Sound waves almost always go through a metal frame.

• Why light travels faster: Light waves travel faster than electrical signals even though they don't have to crash in electromagnetic waves to particles.
