The prokaryotic cells do not have a nucleus or membrane bound organelles
shepuryov [24]3 years ago
3 0

Answer:

Prokaryotes are the most primitive form of life that exist on earth. They came before eukaryotes.

The main difference is the presence of nucleus which is present in eukaryotes and absent in prokaryotes.

The genetic material of prokaryotes are dissolved in the cytoplasm whereas in case of eukaryotes the genetic material is in-tacked inside a double membrane organelle nucleus.

There are many more membrane bound cell organelles found in eukaryotes that are absent in prokaryotes.

DerKrebs [107]

In a small cramped kitchen, you and some friends are preparing a spaghetti dinner. the water is boiling and the pasta is now ready to be carried to the sink to drain. you pick up the pot of bubbling pasta water and start in the direction of the sink. the pot holder slips slightly, causing the water to splash onto your arm. the scalding water burns your forearm. you are experiencing a lot of pain, with a red, blistering burn on your arm.

The appropriate first response will be to cool the affected arm under running water and application of ice pack. The cold temperatures will lower the pain that is being felt.

What components of the introns of nuclear genes that encode proteins in higher eukaryotes are conserved and required for the cor
leonid [27]

Answer:

The introns of protein-encoding nuclear genes of higher eukaryotes almost invariably begin (5') with GT and end (3') with AG. In addition, the 3'subterminal A in the “TACTAAC box” is completely conserved; this A is involved in bond formation during intron excision.

Leviafan [203]
Answer:200m


Explanation: If we do the math here we will see that they multiplied 1,000 by 100 to get 100,000 so we will multiply the 2 by 100 and we will get 200.

Describe stages of cell signaling: a. List and describe the three stages of cell signaling. b. List the three types of receptors
liraira [26]

Answer:

a.There are three signaling pathway

1- Reception in which molecule binds to receptor

2- Signal transduction in which activation of intracellular pathway and enzyme occur.

3- Cellular response in which specific response of cell occur according to receptor and ligand.

b. Three types of receptors are

1- autocrine

2- paracrine

3- endocrine.

Explanation:

autocrine receptors are signaling pathway in which cell releases its molecule and bind to its own cell receptor example cancer cells while paracrine in which ligand binds to other nearby cell receptor and it is used during development  and in endocrine cell target distinct cell and travel through blood stream like hormones functioning.

Which of the following statements best exemplifies the difference between a population and an individual?
Misha Larkins [42]

Answer:

d. All of the above exemplify the difference between a population and an individual.

Explanation:

A population is a group of individuals of the same species that live in a particular geographical area and are able to interbreed. A population is described with respect to several features such as death and birth rates, age structure, density, dispersion, change in the population size due to density-dependent and density-independent factors and the survivorship curve.

These features are not exhibited by a particular individual. Natural selection also works at populations. The evolutionary forces act upon populations to change their allele and genotype frequencies. Therefore, populations are the unit of evolution and change genetically over time, not the individuals. Population ecology studies the size of a populations and the trends and causes of changes in the populations over time.
