Prokaryotes, such as bacteria and archaea, lack a membrane-bound nucleus and other internal membrane-bound organelles, while eukaryotes, including animal, plant, and fungal cells, have a nucleus surrounded by a nuclear membrane and contain multiple internal membrane-bound organelles.
The main difference between Eukaryotes vs Prokaryotes pertains to their cell structure.
Prokaryotes, such as bacteria and archaea, do not have a membrane-bound nucleus where their genetic material is housed.
Instead, their DNA is located within a region known as a nucleoid.
These cells also typically lack other types of membrane-bound organelles.
On the other hand, eukaryotes, including animal, plant, and fungal cells, have a nucleus enclosed by a complex nuclear membrane, and this nucleus contains the cell's DNA.
Eukaryotes also have other internal membrane-bound organelles, giving it additional complexity.
This key structural difference significantly impacts how these cell types operate and interact.

Answer:
Explanation:
Prokaryotes have are simple celled and do not have a nucleus while eukaryotes are more complexed and have a nucleus.
Answer:
The last one
Explanation:
Archaeopteryx
Enantiornithes
Paleognathae
Answer:
A bird or feathered dinosaur is Archaeopterix.
Explanation:
Archeopteryx is an extinct genus of primitive birds, with intermediate characters between feathered dinosaurs and modern birds.
Archeopteryx lived in the Upper Jurassic Period about 150 million years ago, in what is now southern Germany, during a time when Europe was an archipelago of islands in a shallow warm tropical sea, much closer to the equator of what is now.
Answer:
A bird or feathered dinosaur if Archaeopteryx.
AIDS still meets the definition of a pandemic.
Your claims should be supported by scientifically complete evidence.
Follow the steps provided to research, plan, and create your presentation. This guide about the research process can help.
Time to complete: 2 to 3 hours
Part A: Ask Questions
Begin by creating a list of questions to guide your research and help you form a convincing argument. Your presentation should answer some of these questions:
What is the definition of a pandemic?
How does a pandemic differ from an endemic or epidemic?
What is the life cycle of the HIV virus once it enters the body? How does the genetic code
of the virus change?
How does HIV affect the body?
How do people become infected with HIV?
How does AIDS develop from an HIV infection?
What are the current infection rates of HIV across the globe?
Where is HIV/AIDS most prevalent?
What treatments are currently available for HIV/AIDS?
Do some regions of the world have better access to treatments than others?
What is the average life expectancy for someone with HIV?
Does life expectancy differ around the globe?
Now write four additional questions about HIV/AIDS that could help strengthen your argument in the presentation.
Based on the information given, a pandemic simply means the spread of an infectiousdisease.
It should be noted that the difference between an epidemic and a pandemic is the degree if its spread.
HIV is simply a virus that attacks the immune system. It can be gotten through unprotected intercourse, sharing sharp objects, etc. It should be noted that in the long run, HIV leads to AIDS.
It should be noted that HIV is most prevalent in Sub Saharan Africa. There are presently no cure for HIV but there are medications to control the complications.
The average life expectancy for someone with HIV is 56 years.

Answer:
In the population of the study, mutation in the achondroplasia gene is unusually high
Explanation:
In this population, the incidence of genetic mutation that leads to achondroplasia would be 6 children for every 30,000 births. In the general population, achodroplasia has an incidence of 1 per 30,000 births, which indicates that in this specific population, the mutation rate is high above average, which can be explained by a high prevalence of the gene in the population.
Achondroplasia is a genetic disease with inheritance of an autosomal dominant pattern and to suffer from the disease, only one copy of the defective gene is necessary.However, in recent years after several studies it has been possible to demonstrate that even achondroplasia could be generated even in new mutations in the germ cells of the parents.
B. above and below the structure because the heads attract water
C. nowhere because the entire structure repels water
Water most likely to be found in the presence of the phospholipid bilayer above and below the structure because the heads attract water. Option B
