What kinds of organisms use anaerobic respiration?
Answer:
Certain prokaryotes, including some species of bacteria and Archaea, use anaerobic respiration.
Explanation:
For example, the group of Archaea called methanogens reduces carbon dioxide to methane to oxidize NADH. These microorganisms are found in soil and in the digestive tracts of ruminants, such as cows and sheep.

Pepsin is an enzyme produced in the stomach. Pepsin has an optimum pH that is very acidic, between a pH of 1.0 and 2.0. In an
experiment involving the enzyme pepsin, the pH is raised from 2 to 11. What will be the MOST LIKELY effect of this on the reaction?
Explanation:
the pepsin enzyme will not be able to work in a basic medium when ph raised from 2 to 11 it's efficiency will be affected and will not be in a condition of digesting protein .
plz mark my answer as brainlist plzzzz.
hope this will be helpful to you .
When the pH is raised from 2 to 11 the most likely effect on the reaction is ;
The rate of reaction will decrease/delayed
Given that Pepsin enzyme has an optimum pH of 1.0 to 2.0, it will perform efficiently as a catalyst in an experiment whose pH levels fall within the range of the optimum pH of Pepsin.
Pepsin enzyme accelerates the digestion of proteins therefore when the pH levels are raised above 2.0 the efficiency of Pepsin enzyme will be negatively affected and the digestion of protein will require a higher activation energy.
Hence we can conclude that When the pH is raised from 2 to 11 the most likely effect on the reaction is The rate of reaction will decrease/delayed.

answer:
the.answer.is.b
B B B
One of the main ways that evolution occurs in prokaryotes is through mutations that occur during binary fission, which is present in Option C. In prokaryotes, which are single-celled organisms that lack a nucleus, evolution occurs primarily through mutations that occur during binary fission.
What is mutation?Prokaryotes, which include bacteria and archaea, are unicellular organisms that lack a nucleus and other membrane-bound organelles. They are known for their remarkable adaptability and ability to evolve rapidly in response to changing environmental conditions, and beneficial mutations that improve an organism's fitness, such as antibiotic resistance, can quickly spread through a population through natural selection.
Hence, one of the main ways that evolution occurs in prokaryotes is through mutations that occur during binary fission, which is present in Option C.

4. How do enzymes affect the speed of a chemical reaction?
Answer:
Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.

Read the following scenario to answer this question:[/HTML]Mike loves to cook. He heard that if you add salt to water, it will boil faster. If it’s true, it could save him a lot of time in the kitchen. He decided to perform an experiment to test this hypothesis. He set up three pots, each containing three liters of water. In the first pot, he didn’t add any salt; in the second pot, he added one tablespoon of salt; and in the third pot, he added two tablespoons of salt. He got out his stop watch and turned the stove on under all three of the pots.Is there a control group, and if so, what is it? ____________________

When measuring the brightness of a star, what is a limitation of using apparent magnitude rather than absolute brightness?
Apparent magnitude does not use the star's color or temperature.
Apparent magnitude is only theoretical, thus its value cannot be directly measured with equipment.
Apparent magnitude does not take into account the fact that not all stars are the same distance from Earth.
Apparent magnitude is only on a comparative scale that determines how bright a star looks from a theoretical distance of 32 light-years from Earth.
Answer:
D. Apparent magnitude is only on a comparative scale that determines how bright a star looks from a theoretical distance of 32 light-years from Earth.

The seed capsules of the Himalayan balsam plant explode when touched and can eject seeds as far as 16 feet from the parent plant. Is this a structural adaptation, behavioral adaptation, or both?
Answer:
behavioral adaptation
Explanation:
A structural adaptation is defined as the adaptation in which physical features of organisms or plants while behavioral adaptation is defined as the activities an organism or plant do to survive.
The Himalayan balsam plant is an example of behavioral adaptation because it disperse its seeds when it ripe and touched by someone, for its survival it shows it dispersal behavior and spread seeds as far as 16 feet from the parent plant. In the fear of someone can harm by touching it, the survival instinct of balsam plant shows behavioral adaptation.
Hence, the correct answer is " behavioral adaptation".
