This reaction is fundamental to the body's endeavors to accomplish recuperation and resume homeostasis. With the loss of bulk, we lose this metabolic supply.
Organ save alludes to the useful limit of our organs to help life. When we're youthful, our organs have ordinarily the limit that it takes to just capacity. Elements that pressure those organs, similar to disease, damage and lethality we experience in our surroundings (pesticides, and so on.), test the organs, but since they have generous hold, don't charge their cutoff points. As we age, this hold lessens, and the organs turn out to be genuinely worried by these same variables. We just don't ricochet back the way we used to.
Answer:
When patient takes in antibiotics the resistance bacteria gets a competitive survival advantage over the normal sensitive bacteria and hence grows faster.
Explanation:
- Bacteria can acquire resistance by taking in plasmids containing MDR (Multi-Drug Resistance) gene cassettes. The MDR genes produces proteins that can:
- Render the antibiotic ineffective to act on its target by inducing chemical modifications on the drug.
- Promote efflux of the drug from the bacterial cell so that the drug cannot act upon its target.
- When a healthy person ( having no prior exposure to the antibiotic) is infected by bacteria ( both sensitive and resistant varieties):
- A competition develops for the host cells and nutrients between the sensitive and the resistant variety.
- This mutual competition restricts either of the sensitive or resistant bacterial strain to grow profusely.
- When a person (having prior antibiotic exposure), gets infected by bacteria ( both sensitive and resistant varieties) and is exposed to the same antibiotic:
- The sensitive variety, due to its sensitivity towards the drug, gets killed.
- The resistant variety, due to its MDR genes, bypasses the lethal effect of the drug and survives.
- These surviving resistant bacteria can now infect all the available host cells and utilise all the available nutrients without facing any competition and multiply rapidly.
Answer:
The correct answer is - option A
Explanation:
Phosphoinositide 3-kinases or PI-3 kinse, are enzymes involved in essential cellular functions such as the growth of the cell, proliferation, motility, differentiation, survival and intracellular movement, which in turn are plays role in cancer.
PI3-kinase with oncogene PIK3CA and tumor suppressor PTEN, is implicated in the insensitivity of cancer tumors.
Thus, the correct answer is option A)
Bacteria in general grow optimally when the pH is around 7 (5-9 let's say). That is not to say that there are not bacteria that grow in extremely acidic conditions, like in our stomach, or others in extremely basic conditions, like the conditions near volcanoes. Nonetheless, bacteria that grow in food prefer acidic environments over basic ones and usually cannot tolerate the acidity of fruits which is around 4 pH for the most acid ones. For example, stuff like milk and bread that have a pH from 5-6 are prime examples of food where bacteria would thrive. Thus, the correct answer would be b.

The fossil evidence found in these sedimentary layers best implies that animals evolved bony skeletons after shells
Explanation:
Fossil is not only describing when organism lived, but it also gives information about the “progression and evolution of life” on this earth over millions of years. Fossils also give information that previous life in earth is different from present life.
According to evolutionist around 500 million years ago complex internal skeleton organism came into existence. They told fish had firstly evolved and they dominated the sea. Fossilization is very rare process.
