Which of the following accurately describes one part of the hierarchy of organization in living systems?
A : Tissues are made up of various cell types.
B : Organs are made of of various organ systems.
C : Cells are made of various organs.
D : Tissues are made up of various organisms.

Answers

Answer 1

Answer:

A : Tissues are made up of various cell types

Explanation:

B : can't be correct because a system is made of many things, so an organ system is made of many organs. As such, it doesn't make sense for organ systems to make up organs.

C : can't be correct because cells make tissues, and tissues make organs, so cells can't be made of organs

D : can't be correct because an organism is the whole living being. Organisms are made of organs, and organs are made of tissues, so tissues can't be made of organisms.

That just leaves A!

1. Describe one observation that supports the theory that mitochondria and chloroplasts originated as independent prokaryotic organisms


2.Explain how a symbiotic relationship like the one described in the endosymbiotic theory would have benefited each cell.

Answers

Answer: hope the below answers will help

Explanation:

1 and 2 in this paragraph

SKILLS TO DEVELOP

Briefly describe what is meant by the endosymbiotic theory.

Give some evidence supporting the theory that mitochondria and chloroplasts may have arisen from prokaryotic organisms.

It is thought that life arose on earth around four billion years ago. The endosymbiotic theory states that some of the organelles in today's eukaryotic cells were once prokaryotic microbes. In this theory, the first eukaryotic cell was probably an amoeba-like cell that got nutrients by phagocytosis and contained a nucleus that formed when a piece of the cytoplasmic membrane pinched off around the chromosomes. Some of these amoeba-like organisms ingested prokaryotic cells that then survived within the organism and developed a symbiotic relationship. Mitochondria formed when bacteria capable of aerobic respiration were ingested; chloroplasts formed when photosynthetic bacteria were ingested. They eventually lost their cell wall and much of their DNA because they were not of benefit within the host cell. Mitochondria and chloroplasts cannot grow outside their host cell.

Evidence for this is based on the following:

Chloroplasts are the same size as prokaryotic cells, divide by binary fission, and, like bacteria, have Fts proteins at their division plane. The mitochondria are the same size as prokaryotic cells, divide by binary fission, and the mitochondria of some protists have Fts homologs at their division plane.

Mitochondria and chloroplasts have their own DNA that is circular, not linear.

Mitochondria and chloroplasts have their own ribosomes that have 30S and 50S subunits, not 40S and 60S.

Several more primitive eukaryotic microbes, such as Giardia and Trichomonas have a nuclear membrane but no mitochondria.

Although evidence is less convincing, it is also possible that flagella and cilia may have come from spirochetes.

EXAMPLE 7.8.1

Briefly describe what is meant by the endosymbiotic theory.

Give three points of evidence supporting the theory that mitochondria and chloroplasts may have arisen from prokaryotic organisms.

Solutions

The endosymbiotic theory states that some of the organelles in eukaryotic cells were once prokaryotic microbes.

Mitochondria and chloroplasts are the same size as prokaryotic cells and divide by binary fission.

Mitochondria and chloroplasts have their own DNA which is circular, not linear.

Mitochondria and chloroplasts have their own ribosomes which have 30S and 50S subunits, not 40S and 60S.

Summary

The endosymbiotic theory states that mitochondria and chlopoplasts in today's eukaryotic cells were once separate prokaryotic microbes.

An active transport process by which a vesicle moves a large substance out of the cell is known as __________.

osmosis
endocytosis
exocytosis
diffusion

Answers

Answer:

I'm pretty sure it is exocytosis. Because exocytosis transports vesicles out of the cell through the plasma membrane. Remember it as "exo" = exit.

Answer:

C. Exocytosis

Explanation:

The first thing we notice is that the question says "active transport". Looking at the answer choices, we see that "osmosis" and "diffusion" are options.

However, remember that osmosis (the diffusion of water from high to low concentration) and diffusion (the movement of particles from high to low concentration) are both passive transport; in other words, they don't require an input of energy. So eliminate them.

Now look at endocytosis and exocytosis. "Endo" means "inner", so "endocytosis" means the cell is engulfing a substance and bringing it inside. However, we want the process where a substance is moved out.

"Exo" means "out", so "exocytosis" means to expel something. That matches here, so our answer is C.

Your choices should be of relative importance during the time, and not in the long term. Remember, if you help people long term, and the short term dies, then most likely the long term people will die as well.

In the excerpt, it shows that there is enough drugs for 5 groups of people. It is also stated that 15% of the population will die. Note that "will" means necessary, which means they cannot be healed at any point of time.

Young children between birth and 5 years: Those who were borned during sometimes have a better immune system against the disease (as seen in many past instances), as their body has grown accustom to it. However, they are also the group with the highest risk. Their autoimmune system has not developed fully to be able to fight off the disease if it really takes into effect. As the ones that will be part of the next generation, they should receive the dose.

Public Servants like the Police and Fire Department: These are the ones who will have the most human interaction, especially during a high infection state (in which people will be quarantined like we are). Because of this, they should also receive their dose, as their human interaction per day-to-day basis is higher than most of us.

All Adults between 20 and 40, determined to be the highest risk for severe symptoms: Adults who are between 20 - 40 are at the prime of their age, and generally would have the strongest immune system. However, note that these people are located in the highest risk of symptoms. Remember, viruses can evolve, and so if those who are at their peak immune system and are those who most likely would travel around (and most likely not follow government orders of isolation) would have not only the highest chances of infection, but also the highest chances to spread the infection.

Utility industry employees: Utilities such as water, electricity, as well as plumbing, etc. are essential in being kept in order for people to continue to stay at home. This also means that there must be people to keep it in order and running. These people are essential in continuing the way of life for the people.

Food Industry employees: Everybody needs to eat (as well as drink), and there must be a dedicated source for such. This means while they may be able to set up a way to help isolate the people to safer distances, they should not close down. Remember, food, utility, and water make up the foundation of what is important for a human.

As for what the other groups would have to do to prevent the disease, they should stay isolated as much as they can, and to wear disposable gloves and masks when they go outside. They should also wash their hands as much as they can, and avoid to touch their mouth & face with their hands when possible. Avoid contact with others when possible. Work that can be done at home should be moved to home/online.

Possible death of the 5%:

Infants: While they may develop immunity in the beginning stages, they are also the ones that will not have developed immune system. This puts them in a hazardous yet safe place, which is why they get the cure.

Healthcare workers: Healthcare workers will be knowingly exposed to the disease. However, as they know they have a high chance of being exposed to it, they can take the necessary precautions to avoid coming in contact with it, something other groups cannot. However, I feel like the Healthcare workers should have fallen under the umbrella of Public Servants, but since it does not, I will include it here.

Any of the Employees: Employees are employees as they need the steady income from somewhere. As many may be living pay check to pay check, they may feel the pressure build up when they do not work, and may force themselves to disobey government orders and go work. They will have a higher chance to be exposed to the disease, and therefore, in turn, have a low-medium to high chance of being exposed and die of the disease.

High risk areas: They are high-risk for a reason, and so they will have a higher chance of not only contracting, but with failure of noticing the symptoms, to die of it as well.

As for the other groups, I do not have the room to give out exactly why they should stay at home. However, for your job, you can essentially write that their jobs are not essential in keeping humanity alive. Those who can will continue to work through home and the internet or other means, while the others will risk too much just to work. Those jobs that are not essential to meeting human needs or essential in finding the cure for the disease should stop at once.
