Answer:
The main difference is that EUKARYOTIC cells have a nucleus while a PROKARYOTIC cell does not. Instead, prokaryotes have free floating genetic material.
Explanation:
To help you remember this distinction:
EU = YES eukaryotes HAVE a nucleus.
PRO = NO prokaryotes DO NOT have a nucleus.
I hope this helps and good luck with your assignment.
Explanation:
A prokaryotic cell is not as complex as an eukaryotic cell,
the eukaryotic cell also has a nucleus in which it stores the cells genetic material while prokaryotic cells don't have a nucleus and have a free-floating genetic material.

In studying a particular biomolecule (a protein, nucleic acid, carbohydrate, or lipid) in the laboratory, the biochemist first needs to separate it from other biomolecules in the sample (that is, it needs to be purified). Specific purification techniques are described later in the text. However, by looking at the monomeric subunits and functional groups of a biomolecule, you should have some ideas about the characteristics of the molecule that would allow you to separate it from other molecules. Look for differences in ionizable groups, polarity, solubility in water, size, and shape. Based on the characteristics of each type of molecule, select the way(s) in which amino sugars such as glucosamine could be separated from steroid hormones such as estradiol
Answer:
Sugars can be separated from steroidal homones by observing the solubility of these two molecules in water and observing the presence of a negatively altered group in one of the two molecules.
Explanation:
Steroid hormones are molecules derived from cholesterol and usually present a negative change in their structure, which differs from sugars such as carbohydrates and allows these two molecules to be purified, being isolated from each other.
Another way of purifying these two molecules is to observe the solubility of both in water, since sugars are completely soluble in water, without altering the osmotic balance of the cells, however, the same cannot be observed with steroid hormones.
describe the role of bacteria in fermentation.
(please do not give me the google defenition it doesnt even make sense to me)
The bacteria (yeast if im not mistaken) will respire anaerobically, breaking down glucose into ethanol and carbon dioxide
Ask me if you still confused
fermentation is basically a metabolic process used by bacteria under anaerobic conditions to generate energy for cell growth
some words mentioned -
anaerobic : "living, active, occurring, or existing in the absence of free oxygen"
metabolism / metabolic : "chemical processes that occur within a living organism in order to maintain life"
well, hope that explains :) feel free to ask any questions related

Describe the lysogenic cycle.
Answer: the lysogenic cycle happens after the lytic cycle and affects the 2 daughter cells because it infects them. Doing so it disrupts the rest of the cycle of the forming cell. the virus then detaches from the host and begins spreading it's dna or rna before completely overtaking that cells causing it to explode. in doing so the virus spreads even more after causing the cell to burst
Answer:
Lysogeny, or the lysogenic cycle, is one of two cycles of viral reproduction. Lysogeny is characterized by integration of the bacteriophage nucleic acid into the host bacterium's genome or formation of a circular replicon in the bacterial cytoplasm. Hope this helps
Describe the information displayed by ecological pyramids Use all three pyramids (number, biomass, and energy in your answer.
Explanation:
Edit
An ecological pyramid (also trophic pyramid, Eltonian pyramid, energy pyramid, or sometimes food pyramid) is a graphical representation designed to show the biomass or bioproductivity at each trophic level in a given ecosystem.
A pyramid of energy represents how much energy, initially from the sun, is retained or stored in the form of new biomass at each trophic level in an ecosystem. Typically, about 10% of the energy is transferred from one trophic level to the next, thus preventing a large number of trophic levels. Energy pyramids are necessarily upright in healthy ecosystems, that is, there must always be more energy available at a given level of the pyramid to support the energy and biomass requirement of the next trophic level.
A pyramid of energy shows how much energy is retained in the form of new biomass at each trophic level, while a pyramid of biomass shows how much biomass (the amount of living or organic matter present in an organism) is present in the organisms. There is also a pyramid of numbers representing the number of individual organisms at each trophic level. Pyramids of energy are normally upright, but other pyramids can be inverted or take other shapes.
Ecological pyramids begin with producers on the bottom (such as plants) and proceed through the various trophic levels (such as herbivores that eat plants, then carnivores that eat flesh, then omnivores that eat both plants and flesh, and so on). The highest level is the top of the food chain.

How do ribosomes and the Golgi apparatus interact to maintain homeostasis? A. Ribosomes transport proteins and enzymes that are synthesized by the Golgi apparatus. B. Ribosomes store liquids and other waste products that are created by the Golgi apparatus. C. Ribosomes synthesize proteins that are sorted and packaged by the Golgi apparatus. D. Ribosomes store molecules that are converted into usable energy by the Golgi apparatus.
The proteins that are generated by the ribosomes are stored in the Golgi apparatus.
What is the Golgi apparatus?
Golgi apparatus is also called the Golgi complex or Golgi body. It is a membrane-bound organelle present in eukaryotic cells. It is made from a network of flattened stacked structures called cisternae.
The Golgi apparatus is responsible for the transportation, modification, and packaging of the proteins and lipids molecules into small vesicles. These vesicles are delivered to their destinations.
This organelle is embedded in the cytoplasm right after the endoplasmic reticulum. It is located near the cell nucleus. These are present in hundreds of plant cells.
They help in the transport of secretory proteins, cell membrane proteins, lysosomal proteins, glycoproteins etc. They also help transport some glycolipids. Much of the material for the cell wall passes through the Golgi apparatus.
Therefore, the Golgi apparatus helps in protein packaging.

An example of a communicable disease is
cancer.
chronic respiratory disease.
diabetes.
giardiasis.
Answer:
D
Explanation:
I chose it before .
Answer:
It is D because communicable diseases, also known as infectious diseases or transmissible diseases, are illnesses that result from the infection, presence and growth of pathogenic (capable of causing disease) biologic agents in an individual human or other animal host.
SO with the procces of elemination you can see that you can't contract cancer because that is something that can be inherited. Chronic Respiratory diesase can be inherited or developed throughout the years same as diabetes. Hence the answer being D

Nerve cells, also known as neurons, are the basic building blocks of the nervous system. They are responsible for transmitting electrical and chemical signals throughout the body. Neurons have a cell body, which contains the nucleus and other organelles, and specialized extensions called dendrites and axons.
Dendrites receive signals from other neurons, while axons transmit signals to other cells, such as other neurons or muscles. The signals are transmitted across a small gap called a synapse, which can be chemical or electrical. Neurons are specialized for the rapid transmission of information, and are capable of generating electrical impulses called action potentials that travel along their axons.

Answer:
Overreacts to an antigen.
Explanation:
Thats what an allergy is if you think about it
A person who has allergies has a compromised immune system because the body's immune system overreacts to an antigen.
What do you mean by Allergy?Allergy may be defined as a reaction by our immune system to something that does not trouble most other people. It affects a person more specifically.
When a person gets affected by any allergy, the immune system of that person may overreact by producing more antibodies. These antibodies attack the allergen particles and cause adverse symptoms.
Therefore, a person who has allergies has a compromised immune system because the body's immune system overreacts to an antigen.
