are phenols and glycosides induced or pre-existing defenses mechanisms for plants immunity ?
Phenols and glycosides are pre-existing defense mechanisms in plants' immune systems. These compounds are part of the plant's chemical defense arsenal and are present in various tissues even before any attack or infection occurs.
Phenols are secondary metabolites found in plants that have antimicrobial and antioxidant properties. They contribute to the plant's defense against pathogens by inhibiting the growth and development of microorganisms. Phenols also play a role in wound healing and lignification, which strengthen the plant's cell walls.
Glycosides are another class of secondary metabolites found in plants that have diverse functions, including defense against herbivores and pathogens. Some glycosides act as toxic compounds when ingested by herbivores, while others can inhibit the growth of microorganisms or interfere with their feeding behavior.
Both phenols and glycosides are produced by plants as part of their constitutive defenses, meaning they are present at baseline levels even in the absence of stress or attack. However, their production can be further induced or enhanced in response to specific stimuli, such as pathogen invasion or herbivore feeding.

how were the designs Pasteur's and Redi's experiments different?
Answer:
Francesco Redis experiment was conducted in 1668. His experiment was centered around the idea that maggots will arise from rotting meat. He conducted an experiment through his hypothesis that the maggots actually came from eggs laid by flies on the meat. To prove this he placed a piece of meat on 3 separate jars. He left one of the jars completely open, another sealed, and another covered by gauze. His hypothesis was proved to be correct when the only piece of meat that had maggots was the one that was left open.
Louis Pasteurs experiment was conducted in 1858. His experiment was influenced by a similar failed experiment conducted by Lazzaro Spallanzani in 1768. He was trying to prove that the air was not what was making the broth cloudy but what was actually making it cloudy was tiny microorganisms getting inside. To prove this, he created a swan neck flask that allowed air to come inside but trapped the microorganisms in a pocket on the flask.
Differences:
Redi used meat in his experiment while Pasteur used broth.Redis experiment was to disprove Aristotles idea that some life forms arise from non living matter. while Pasteurs experiment was to disprove the idea that air gives life force.Redis experiment was conducted in jars while Pasteurs was conducted in a hand made swan neck flask.Explanation:

species. Select ALL that apply.
Several factors were important for the extinction of mammoths to mastodons, and natural selection of the elephant, mainly the ecosystem they lived in and the search for food.
What are the differences between the mammoth and the elephant?The mammoth is an animal that was once extinct and belonged to the genus Mammuthus and the family Elephantidae which included the proboscidians. Elephants differ from mammoths in that mammoths had their bodies covered with hair. Also, elephants are slightly smaller than mammoths.
What are the differences between the mastodon and the elephant?Both were herbivores, but the mastodons had conical-shaped teeth designed to crush leaves and branches more easily. Mammoths had rough molars, allowing them to cut through vegetation and graze like modern elephants.
Whit this information, we can conclude that several factors were important for the extinction of mammoths to mastodons, and natural selection of the elephant, mainly the ecosystem they lived in and the search for food.

92ml 3.0 fl oz what is the ratio
The ratio between 92 mL and 3.0 fl oz is 46 : 44, or it can be further simplified to 23 : 22.
To find the ratio between 92 mL and 3.0 fl oz, we need to convert the units to a common measurement. Let's convert 3.0 fl oz to milliliters (mL).
1 fluid ounce (fl oz) is equal to approximately 29.5735 milliliters (mL).
Therefore, 3.0 fl oz is equal to 3.0 * 29.5735 = 88.72 mL (rounded to two decimal places).
Now we can express the ratio between 92 mL and 88.72 mL:
92 mL : 88.72 mL
Simplifying the ratio by dividing both sides by the greatest common divisor, we get:
46 : 44
So, the ratio between 92 mL and 3.0 fl oz is 46 : 44, or it can be further simplified to 23 : 22.

How does aerobic respiration differ from anaerobic respiration ?
I need long answer, and correctly explained.
Answer:The difference between aerobic and anaerobic respiration.
Aerobic respiration Anaerobic respiration
1. Aerobic respiration refers to complete breakdown of metabolic fuels in presence of oxygen. 1. Anaerobic respiration is the process of partial breakdown of fuel (glucose) in absence of oxygen.
2. It includes glycolysis, citric acid cycle and oxidative phosphorylation. The first two processes take place in the cytoplasm while last one occurs in mitochondria. 2. Glycolysis is followed by ethanol fermentation (occurs in yeast) or lactic acid fermentation (in muscles and microbes like lactic acid bacteria).
3. The end products are carbon dioxide and water. 3. End products of ethanol fermentation are ethanol and carbon dioxide; that of lactic acid fermentation are lactic acid
4. Owing to complete oxidation of glucose, a large amount of energy is produced (36-38 ATP molecules) 4. Incomplete oxidation of glucose does not release all stored energy and only 2 ATP molecules are produced.
Anaerobic respiration is carried out by yeast and other anaerobic organisms like lactic acid bacteria, E. coli, Staphylococcus, Clostridium etc.
