Answer:
i).number of generations that is possible in individual cultures of C. elegans is 42 .
ii)number of generations that is possible in individual cultures of B elegans IS 8640.
b). When the Caenorhabditis elegans and bacillus thuringiensis have controlled growth their are no immune response to each other hence they are not adapted to each other for separate growth.
c)The relative change in B. thuringiensis virulence was greater than the relative change in C. elegans resistance because B thuringiensis had more number of generation event 8640 after 150 days while C elegans had less number of reproductive event 42.
Step-by-step explanation
explanation.
a) i).number of generation for C elegans will be given by;
growing period divided by generation time.
we have ;
generation time is 3.5 day
growing period is 150 day.
then number of generation of c will be;
150/3.5=42 generation
ii).number of generation for B thuringiensis is given by;
but we have;
generation time is 25 minutes
growing period is 150 days.
then substituting in the formulae we have ,
150 x24 x60/25=8640 generation.
we have used the relation ;
1 hour =60 minutes and 1 day = 24 hours
b).When the Caenorhabditis elegans and bacillus thuringiensis have controlled growth their are no immune response to each other hence they are not adapted to each other for separate growth. when grown together they provide the host pathogen relationship protecting the growth for each organism. B thuringiensis secrets toxin to infect the host hence having much change while C elegans are protected from this chemical since the change is high.
c).The relative change in B. thuringiensis virulence was greater than the relative change in C. elegans resistance because B thuringiensis had more number of generation event 8640 after 150 days while C elegans had less number of reproductive event 42.
B. thuringiensis have smaller genome size hence have more change .This change is caused when trying to infect C elegans hence causing a more diverse change in B thuringiensis.
C elegans genome are relatively high since they have less number of reproductive event hence being protected because they produce the immune response by growing together to show maximum changes when separately grown.

What is Chemo synthesizer?Chemo synthesizer is also called as Chemoautotrophs. Chemoautotrophs are defined as organisms that perform chemosynthesis which include certain groups of bacteria such as sulfur-oxidizing gamma proteobacteria, epsilon proteobacteria, and neutrophilic iron-oxidizing bacteria, and some archaea such as methanogenic archaea.
Chemoautotrophs performed chemosynthesis which is describe as the process in which bacteria make food with chemical energy. In this process, one or more carbon molecules are converted into organic matter.
Thus, most bacteria is an example of a chemo synthesizer. So, the correct option is (B).

How did Robert Koch proved the germ theory disease
Answer:
In the final decades of the 19th century, Koch conclusively established that a particular germ could cause a specific disease. He did this by experimentation with anthrax. Using a microscope, Koch examined the blood of cows that had died of anthrax. He observed rod-shaped bacteria and suspected they caused anthrax.

How many years does a snake live and how many times does it change its skin without pictures please and without links
Answer:
9 years
Explanation:
Boa constrictor: 30 years
Boa constrictors are native to North, Central, and South America, mainly dwelling in rainforests. The lifespan for the large, heavy-bodied snake averages about 20 years in the wild, but living in captivity can increase that by 10 to 15 years.
Answer: Some types of snake can live for 2-3 decades, such as the boa constrictor, whereas others, such as garter snakes, will be fortunate to reach 10 years of age. On averge a snack changes its skin up to 2-4 times a year.

Answer: what did u get on it
Explanation:
Case-study.
A 25 years old male with past medical history of alcohol abuse was admitted to the ED with complains of severe lower back and bilateral legs pain. He had been running twelve miles every day for two weeks using 3 lbs weights attached to each leg and 2 lbs weights attached to each arm preparing for the marathon. The other complaint was a dark color urine for two days.
What is the cause of his symptoms. Explain the mechanism.
Answer:
The lower back pain and bilateral leg pain is due to over and intense physical activity which causes stretching of ligaments and muscles resulting in back and leg pain. Such pain can be managed by limited or by reducing physical activity. The dark color of urine is due to the presence of bile (bilirubin) in the urine. Here the patient has a past medical history of alcohol abuse. Excessive alcohol intake enhances gut permeability resulting in enhanced absorption of bacterial endotoxins. Excessive endotoxins in the liver cause damage of the kupffer cells in the liver, resulting in the release of bilirubin in the blood which ultimately passes through kidneys into the urine.
Explanation:
A woman goes to the doctor and is diagnosed with rheumatoid arthritis. What factors led to her developing this disease? Select all that apply. Some of her T cells were not negatively selected. Some of her T cells are not recognizing and associating with her major histocompatibility complex (MHC) proteins. Some of her T cells were not positively selected. Some of her T cells are recognizing and responding to her self antigens.
Answer:
Some of her T cells are recognizing and responding to her self antigens.
Explanation:
Rheumatoid arthritis is characterized as an inflammation in the joints. This inflammation is created by some T cells and their associations with antigens.
Right at the initial stage of the disease, T cells are activated by their own antigens, which makes them respond to this activation by recruiting monocytes and creating antibody-producing cells from the B lymphocyte. T cells also cause the release of free radicals and lysosomal enzymes, in addition to promoting an activation of the high imne complex. All of this, attacks the joints causing an inflammatory process at the site, which justifies the autoimmune character of this disease.
Autoimmune diseases are those in which the elements of an organism's immune system attack the healthy cells of the organism itself, as we can see in the paragraph above.

Explain how one body system not functioning properly can affect another body
system.
Answer with explanation:
If a body system does not work properly then the other body systems will also fail because every system is needed for a person to live properly. For example if the respiratory system does not work properly then the other systems will be harmed as oxygen will not be able to move to other parts of the body. As a result, the kidneys will fail and the heart will stop working and the person will die.
One body system that is not functioning properly can affect another body system because, in an organism, coordination is maintained by the different organ systems. If one system is affected, then others will be too.
How is the body's system functioning?In a multicellular organism, the organism is regulated by the coordination of the different organ systems, such as the circulatory system, digestive system, etc. In the human body, many systems are present, and each system is made up of many organs. In the nervous system, the nerves, brain, and spinal cord are involved, in the circulatory system, the blood, blood vessels, heart, and lungs are involved, and the lungs are involved in the respiratory system too. Because a single organ is involved in multiple organ systems, if one system is affected, the others will be affected as well.
Hence, one body system that is not functioning properly can affect another body system because, in an organism, coordination is maintained by the different organ systems.

Difference between palisade cell and fungal cell
Answer:
Explanation:
Plantae and Fungi are two of the three main kingdoms in the domain Eukaryote (the third group is Animalia, which includes you and me).
Many fungi grow in a way that’s similar to plants. They inhabit similar ecosystems and may even form symbiotic relationships together. Mycorrhizae are fungi that grow on the roots of plants, helping the plants take up nutrients in the soil while the plant provides the fungus with sugar. Of course, most fungi don’t look much like plants.
But the differences between fungi and plants are more than just skin (or bark) deep. While mushrooms often inhabit similar ecosystems to plants, molds and yeasts are even more different from plants!
Looking at a plant cell and a fungi cell under a microscope will reveal some interesting similarities and differences.
