A. plasma membrane
B. nucleus
C. flagella
D. cell wall

Answers

The answer is D, A, C

Nucleus is an exception in a prokaryotic cell. Thus, option A, C and D are correct.

What are the characteristics of a prokaryotes?

Prokaryotes are microscopic and primitive cells. Their nucleus is not well developed.

Prokaryotes lack cell organelles like mitochondria, endoplasmic reticulum, Golgi body etc in their cell structure.

Prokaryotes are simple in assembly and are therefore unicellular. A single cell performs all the functions in the body.

Prokaryotes have single chromosome present in their structure. Their DNA is found in the cytoplasm.

Prokaryotes have cilia and flagella for locomotion.

Prokaryotic organisms are found extensively everywhere on earth. They have unique ability to survive in the harsh environments.

Prokaryotes are beneficial in many ways:

Carry out nitrogen fixation.Important for human gut for the absorption of vitamin B12.Helpful in fermentation process.Important in bioremediation

Therefore, prokaryotes are important in many ways to the ecosystem.

After first exposure to an antigen, about how long does it take for antibodies to reach a detectable level?

2. What could explain the significant increase in antibodies to non-Lyme disease antigens (blue line)?

3. Lyme disease patients who are treated with antibiotics quickly usually do much better than those who are treated later. Why do you think this is the case?

4. Why doesn’t the Antibodies in Lyme Disease Antigens (orange line) decrease after the first immune response, compared to non-Lyme Disease Antigens (blue line)?

5. Professor Dr. Utpal Pal studied the Borrelia burgdorferi bacterium at the University of Maryland. Dr. Pal found that Lyme disease is caused by your immune system. When the body is infected with Lyme disease, it overreacts causing inflammation in the joints. Although antibiotic resistance has not been observed for B. burgdorferi, create an argument defending the control of antibiotic use to the public. Analyze the data in the graph below by answering the following questions. Be sure to use complete sentences.

Answers

After first exposure to an antigen, it can take about three weeks for antibodies to reach a detectable level. The body will react to disease by creating antibodies and testing their effectiveness against the unknown antigen.

Antibodies are the body's way of fighting off foreign threats. Also known as immunoglobulin, they detect and attack pathogenic bacteria and viruses. These antibodies detect a protein that is unique to the surface of the pathogen called the antigen.

At times, we can see an increase in antibodies for one disease, for example, Lyme disease, in the presence of non-Lyme disease antigens. This is often due to antigenic variation, which is a method used by pathogens to mask their respective antigens. There are also general use antibodies that will increase in reaction to any pathogen.

As with any illness, a patient who receives treatment sooner will fare better than those whose treatment is delayed. This is due to the fact that earlier treatment with antibiotics will allow the body to fight off the infection before the bacteria can reproduce further.

After the first immune response, antigen-specific antibodies will remain for some time to provide the body with "immunity" to the pathogen, while general-purpose antibodies will return to a base value.

At this point, 6 carbon dioxide molecules have
been released (2 from the link reaction and 4
from the Krebs cycle). Why does this make
sense?
Glucose has combined with oxygen to make carbon dioxide.
Glucose has 6 carbons and has been completely broken down by this stage.
The 6 carbon dioxides are reactants that will be used to make ATP.
These 6 carbon dioxides are converted to oxygen by respiration.
All of these.

Answers

Glucose has combined with oxygen to make carbon dioxide and Glucose has 6 carbons and has been completely broken down by this stage.

Glucose react with oxygen to make carbon dioxide, water and energy in the form of ATP.  Glucose has 6 carbon atoms which react with oxygen that is  completely broken down into three products such as carbondioxide, water and energy in the form of ATP by the process of cellular respiration so we can conclude that carbondioxide gas is produced by breaking down of glucose molecules from the Krebs cycle that is a stage of respiration.

Answer:

molecules that combine to form proteins

Explanation:

amino acids are molecules that combine to form proteins. amino acids and proteins are the building blocks of life. when proteins are digested or broken down amino acids are left

Amino acids are building blocks of proteins. They contain an amino group, carboxyl group, and side chain. There are 20 types, each with unique properties influencing protein structure and function.

Biochemical functions depend on amino acids in proteins. The R-group, amino group, and carboxyl group are on each amino acid. This side chain gives each amino acid chemical properties that impact protein structure and function. Twenty typical amino acids make up proteins.

They vary in size, shape, charge, and hydrophobicity. Peptide bonds generate polypeptide chains that fold into three-dimensional forms, determining a protein's function. The structures include simple helices and complex globular shapes. Complex and diverse, proteins perform various tasks in living things due to the diversity of amino acids and their interactions.

They consume food and they have much higher metabolism. That means that more waste products are produced. Plants can use much of the waste produced and it is in fact raw material. Animals don't normally produce their own chemicals from scratch like plants normally do so they can't just recycle the waste. They need to remove it. About the only waste plants need to get rid of is excess oxygen produced during the day. That is actually three reasons but recycling is related to plants not consuming but making their own chemicals from scratch. In a way it pretty much comes down to one main reason.

In eukaryotes, gene expression is regulated mostly by _____.

Answers

Answer:

Gene expression in eukaryotic cells is regulated by repressors as well as by transcriptional activators. Like their prokaryotic counterparts, eukaryotic repressors bind to specific DNA sequences and inhibit transcription.

Explanation:

In eukaryotes, gene expression is regulated mostly by transcription factors.

What are transcription factors?

Transcription factors are proteins that bind to DNA in the promoter region of a gene, and they play a critical role in controlling when and to what extent a gene is expressed.

They can either activate or repress gene expression by promoting or inhibiting the recruitment of RNA polymerase. Transcription factors are themselves regulated by a variety of signals, including hormones, growth factors, and other external cues, as well as by feedback loops and other regulatory mechanisms within the cell.

Ultimately, this complex interplay of factors allows eukaryotic cells to precisely control which genes are expressed, when they are expressed, and to what degree, enabling them to respond to changing internal and external environments.
