Answer and Explanation:

Microscope objects have thermal profiles. These profiles differ as a purpose of their physical parameters. Most objects are sold and designed for the resolution of fixed cell microscopy.

 There is little indication that the temperature cycle affects the strain characteristics. A large box can be constructed around the microscope and heated with hot air.

The heating system's cycling causes the specimen to drift out of focus and can also change the coverslip position.

The microscope can be equilibrated to a single temperature to eliminate the movement resulting from the thermal expansion of the microscope's components.

Air currents connecting the specimen chamber should also be reduced—tight control of temperature for the entire laboratory and microscope. Any change in the temperature can lead to unwanted movement in the microscope. Heating ducts often produce localized temperature changes.

Hypothesis A: If heart rate is related to caffeine intake, then coffee drinkers will have higher heart rates.
Katen [24]

Answer: D. Hypothesis B is more useful because it suggests a way to test the relationship between heart rate and caffeine intake.

Hypothesis A and B both are suggesting that caffeine intake is related to higher heart rate. But hypothesis B is proving it more certainly by suggesting the affects of caffeine intake on heart rate. As, heart rate of most people will be higher 30 minutes after they drink a cup of coffee is testifying the fact, that higher heart rate is related with caffeine intake.

Therefore, hypothesis B is more useful because it suggests a way to test the relationship between heart rate and caffeine intake.

Answer:

1. Both neutron stars and black holes are the corpses of stars that died in explosions known as supernovas. Black holes form when the most massive stars die and neutron stars form when stars not as large die. They both have a very strong gravitational pull, but a black hole's pull is stronger than a neutron star. Neutron stars <u>will turn into</u> black holes if the force of gravity breaks the resistance of electrons.

2. White dwarfs are degenerate, which means they can compress matter. The material in a white dwarf no longer undergoes fusion reactions, so it is supported only by electron degeneracy pressure. This causes it to be extremely dense, saving space and energy.

3. A light year is the distance light travels in a year while an astronomical unit is the average distance between the earth and the sun.

4. A convection zone transfers energy by radiation and conduction.

PLEASE HELPPPPP I WILL GIVE BRAINLIEST
Nostrana [21]

Answer:

The correct answer is - because 3×3×3 has the highest Surface area to volume ratio, diffusion in and out of the cell would be faster.

Explanation:

It is known that if the size of a sphere or cell increases, the volume is a cube, and the surface area is squared therefore volume increases faster than the surface area. If the volume is more and the surface area is less than diffusion will be less effective. diffusion takes longer and is less effective.

The decrease in the surface-to-volume ratio leads to diffusion to get less efficient. The Surface-to-volume ratio of a sphere decreases as the sphere gets bigger.
