Sensory receptors in the skin detect the stimuli from the environment.

Explanation:

Simple process of elimination. Keratin is what makes up hair and nails. Muscles cannot detect temperature change, and connective tissue can't either. The sensory receptors that detect heat and cold are called thermoreceptors

How can a human cell in prophase of mitosis be distinguished from human cell in prophase l of meiosis?A. By the presence of kine

Len [333]

Answer:

E. By presence of paired homologous chromosomes in the meiotic cell.

Explanation:

Differences between Mitotic Prophase and Prophase 1 of Meiosis:

The prophase of mitosis is relatively shorter than prophase 1 of meiosis.
Prophase of mitosis is characterized by the disintegration of the nuclear membrane and the movement of the duplicated centrioles towards the two poles of the cell.
Prophase 1 of meiosis is relatively longer and involves a number of consecutive events that do not occur in the mitotic prophase.
Prophase 1 of meiosis involves the disintegration of the nuclear membrane as well. But the most important event of this phase is the pairing of homologous chromosomes through a connection called a synapse. This is called chiasmata formation. Homologous chromosomes pair up in form of tetrads and exchange segments with each other. This process is called crossing over and it is crucial in the production of genetically varied daughter cells.

How does the cell membrane help maintain homeostasis for the cell?

Alenkasestr [34]

I feel like its A because cells cell can homoeostasis by regulating the movement of substances so it would help move the cell.

Hope this helped!

Part b - comparing eukaryotic and prokaryotic cells two fundamental types of cells are known to exist in nature: prokaryotic cel

Alexeev081 [22]

<h3>Answer;</h3>

Prokaryotic only: nucleoid
Eukaryotic only: nucleolus, lysosome, mitochondria
Both: plasma membrane, ribosomes, flagelia

<h3>Explanation;</h3>

Prokaryotic cells are those cells that lack nucleus and other membrane bound organelles, unlike eukaryotic cells which contain a membrane bound nucleus and membrane bound organelles such as mitochondria, and lysosomes.
Prokaryotic cells lack the nucleus and nucleolus, but instead contain a nucleoid which contains the genetic materials of the cell.
Eukaryotic cells on the other hand contain a well defined nucleus, that contains nucleolus and highly complex genetic material.
Despite the differences, they both share a number of organelles and characteristics such as plasma membrane, which regulates the movement of substances in and out of the cells, ribosomes, sites for protein synthesis, and also flagella, for locomotion.
