At what depth(km) would a rock experience temperature of 5500C?
kow [346]

Explanation:

A rock would experience a temperature of 5500°C is about the core which is at a depth of 220km.

But let us use the earth's geothermal gradient to solve this problem.

The geothermal gradient is the rate at which temperature is increasing with depth.

The geothermal gradient 25°C/km

        At 5500°C,

               5500°C x  \frac{1}{25}  \frac{k}{C}  =    220km

But this is not so in nature, there are other heat sources that contributes to increasing temperature with depth such as radioactive heat and frictional heat.

The majority of bacteria have a cell envelope. which component of the cell envelope is found in only some bacterial cells?
lesya [120]

The majority of bacteria have a cell envelope component which serves as an outer compartment.

Explain the Plasma membrane components.

The membrane that divides the interior of the cell from the external environment is known as the plasma membrane, sometimes known as the cell membrane, and is present in all cells.

A cell wall is affixed to the plasma membrane on the exterior of bacterial and plant cells. A semipermeable lipid bilayer makes up the plasma membrane. The movement of materials into and out of the cell is controlled by the plasma membrane.

A cell is protected by its cell membrane, also known as the plasma membrane. Additionally, it offers a stable environment inside the cell. And that membrane serves a variety of purposes. One is to move compounds out of the cell that is harmful as well as nutrients into the cell.

Hence, the correct answer is the outer membrane.

Explain why the process of mitosis is important to you eukaryotic <br> organisms
vichka [17]

The eukaryotic organisms have the process of mitosis but differently than the process of the prokaryotic because the prokaryotic organisms dont have the dna enclosed in a nucleus. Mitosis needs to occur in eukaryotic organims because the cell could keep growing an it is going to be less efficient in moving material across the cell membrane. They reason why mitosis happens is because volume and surface are do not increase at the same rate.

Describe Lamarck’s idea about how organisms evolved. Use the giraffe’s neck as an example.
Murljashka [212]

Answer

Lamarckism, a theory of evolution based on the principle that physical changes in organisms during their lifetime—such as greater development of an organ or a part through increased use—could be transmitted to their offspring.

Lamarck believed that the stretching elongated the giraffe's neck, which became a useful characteristic and was passed onto future generations. This resulted in the length of the giraffe's neck increasing over time. It is now commonly accepted that Lamarck's ideas were wrong.
