explain the difference between an
autotroph and an heterotroph.
Answer:
The answer will be listed below.
Explanation:
Autotroph and heterotroph are two different terms. Autotrophs are producers, such as plants and other organisms that can produce their own food. Heterotrophs are consumers who consumes producers or other consumers to get their food. Examples include animals, people, and those who consume other things for energy.

Use stamen in a sentence
A)Using an example explain how enzyme and habitation exploited to control human diseases
B)Explain why the drug is poisonous to the Target organism but not to humans
Answer:
A. Rifampicin is an example of an enzyme inhibiting drug, since it acts on the bacterial RNA polymerase, preventing the transcription and synthesis of proteins, so the bacteria is not viable and a human disease is controlled.
B. The drugs have specificity by microorganisms —target organisms— which are also smaller and more susceptible, while their effect is minimal or null in human cells and are not poisonous for them.
Explanation:
Bacteria, viruses, parasites and pathogenic fungi are microorganisms capable of producing disease in humans. One of the ways to fight infectious diseases is the use of drugs called antibiotics, capable of interfering with the development of microorganisms.
Antibiotics or antibacterials are capable of preventing the synthesis of the bacterial wall or its reproduction, intervening in the synthesis of proteins. They do this through enzymatic inhibition of these processes.
Rifampicin is a drug capable of coupling itself to one of the sub-units of the RNA polymerase enzyme, changing its configuration and preventing its affinity for its substrate, the bacterial DNA. Rifampicin thus prevents the synthesis of proteins necessary for the development of the bacterium, which dies and thus manages to control an infectious disease.Drugs such as antibiotics act on specific bacterial functions —their target organism— by affecting the functions that allow them to live that allow them to live, as if they were poisoned. These same drugs have little or no effect on human cells when administered in appropriate doses. The few effects that are observed in human cells are not sufficient to kill them, but they do produce effects or secondary reactions, usually called adverse effects.PLSSSSS HURRY

1.How would you describe the relationship between the eagle and the hare?
2.According to the video, why can't the eagle afford any mistakes?
3.How could an overpopulation of eagles affect the hare population?
1)Describe the relationship between a predator population and the population of its prey.
2)What is a keystone species? Give an example.
3)What is a limiting factor? Give an example.
4)What is the role of camouflage in prey and predator?
Explanation:
1. Remember, the video began with the words, "For one death, for the other, are all decided in an instance." Meaning, both could result in each other harm. There is
2. The eagle can't afford to make any mistakes because we are told, "even the slightest injury can leave it too weak to hunt and cause it to stave."
3. More eagles means more hares are hunted, and as more hares are been killed, the lesser the hare population.
4. The increase in the predator population leads to a reduction in the population of the prey. In other words, as more predators start looking for prey to eat, the prey population decreases.
5. In simple words, a keystone species is a type of predator whose presence in the community has far-reaching effects on other species in the community. One common example is the sea star species found in coral reefs, see stars feed on mussel and sea urchin thereby helping to regulate the population of mussels and sea urchin. Doing this ultimately helps other species survive.
6. A limiting factor is an attribute or factor that reduces the exponential growth in the population of an organism.
7. Camouflage allows preys to hid from their predators. Usually made possible by their physical appearance.

Organelles are structures within the cell that perform important functions. Which of the following correctly matches the
organelle with its relationship to the whole cell?
Answer:
mitochondria: powerhouse of the cell
Ribosomes: the places where proteins are synthesized in our cells.
nucleus houses DNA;controls cell
Vacuole: holds waste and fluids from cell
Ribosomes: tiny organelles that contain RNA and specific proteins within the cytoplasm.
Explanation:
Organelles make up the subunits of a cell. There are numerous each with their own function.
There are various cell organelles that play an essential function these are as follow:
MitochondriaNucleusChloroplastEndoplasmic reticulumGolgi bodiesRibosomePeroxisomeWhat is the different role of cell organelles?Mitochondria: Generates energy (ATP) for the biochemical reaction.
Nucleus: Responsible for the synthesis of mRNA, rRNA, tRNA and DNA.
Chloroplast: responsible for Photosynthesis by using sunlight in plant cells.
Endoplasmic reticulum: carry Protein(RER) and lipid synthesis(SER).
Golgi bodies: play role in protein sorting, transporting and trafficking.
Ribosome: two types of ribosomes are present in the cell-free ribosome and membrane-bound ribosomes, responsible for the synthesis of protein.
Peroxisome: play role in fatty acid oxidation and metabolism.
Thus, all these organelles play important functions in cells.
