Answer:
The right answer to this question is: we don't have a specific enzyme called Cellulase.
Explanation:
An enzyme is basically a system known as lock and key mechanism. It works like this: every single enzyme has its own form, and there's only one way of getting into it for the digestion to happen, the substrate needs to complete this system, as a key on a lock, and once this happens, the digestion can start. But humans don't have this enzyme, if they don't have it, the digestion won't happen in this case. Well known animals that have it are the ruminants, they can digest cellulose easily because they have the specific enzyme called cellulase.
Answer:
it impossible for humans to digest the food that contains cellulose because they do have an enzyme which is required to break beta acetal linkage.
Explanation:
cellulose is a polysaccharide and it is synthesized by animals, plants and in plant cell wall major component is cellulose.
it impossible for humans to digest the food that contains cellulose because they do have an enzyme which is required to break beta acetal linkage.
Ruminants such as cows in the rumen symbiotic anaerobic bacteria are present, cellulases enzyme is produced by these bacteria, that help to digest the cellulose.
Answer:
Stars are formed such that their death led to the creation of life.
Explanation:
The Big Bang theory was developed in 1927. This theory helps to understand how the universe was created. According to this theory, hydrogen gas was created through a process of expansion and explosion. As a result, stars are formed such that their death led to the creation of life.
Earth formed around 4.54 billion years ago which is equal to approximately one-third of the age of the universe.
The mutated DNA is TAC CTC ACT GAG CGT.
What is the impact of this particular mutation on the organism? In order to find out, you need to transcribe and translate the codons.
Answer:
The mutation that involves the change in the sequence of DNA bases is reflected both in the transcription of mRNA and in translation, giving rise to an alteration in the protein, which may not function and whose impact on the organism is a morphological or functional alteration.
Explanation:
According to this scenario, the DNA has experienced a mutation by changing the sequence by one of its bases, Cytosine by Thymine, producing in the mRNA a termination codon that interrupts the normal synthesis of the protein, preventing that protein from fulfilling its function. This particular mutation is called Nonsense mutation.
For normal DNA
DNA TAC CTC ACC GAG CGT
mRNA AUG GAG UGG CUC GCA
Protein Met - Glu - Trp - Leu - Ala
For the mutated DNA
DNA TAC CTC ACT GAG CGT
mRNA AUG GAG UGA CUC GCA
Protein Met - Glu - STOP - Leu - Ala
The change of a cytosine by Thymine in the mutated DNA produces that the third codon of the mRNA is altered, encoding a UGA termination codon, which prematurely stops the protein synthesis and originates an incomplete protein, probably not functional, whose impact in the organism is a morphological or functional alteration.
Answer: It is greater when sucrose concentration went from 2.5 to 7.5g/l.
Explanation: The rate of reaction of an enzyme is known to be affected by the rate of concentration of its substrate, which in this case is the sucrose Solution.
If the rate of increase of concentration is high,the activities of the enzyme SUCRASE will increase accordingly, in order to breakdown the substrate.
The rate of increase of Sucrose from 2.5 to 7.5g/l is higher(300%) than the rate of Increase of Sucrose from 22.5 to 27.5g/l (1.22%). It is expected under circumstances that the action of SUCRASE will increase at a rate higher in the first Solution than in the second Solution.
The rate of increase in sucrase activity depends on the concentration of sucrose and whether or not the enzyme is saturated. The increase could be greater at lower concentrations (2.5 to 7.5 g/l) if sucrase is not yet saturated. The increase might be less at higher concentrations (22.5 to 27.5 g/l) if sucrase is near or at saturation point.
The increase in sucrase activity is generally considered to be a response to the concentration of substrate present, in this case, sucrose. The increase in activity happens because more substrate (sucrose) is available for the enzyme (sucrase) to act upon. However, there is a limit to this increase. Once the enzyme is saturated with substrate, further increases in substrate concentration do not increase the enzyme's activity. This is known as the saturation point.
To determine whether sucrase activity increased more when sucrose concentration increased from 2.5 to 7.5 g/l or from 22.5 to 27.5 g/l, we would need specific data on the rate of sucrase activity at these different concentrations. It's possible that the increase from 2.5 to 7.5 g/l was greater if this is in the ascending portion of the enzyme activity curve and the sucrase was not yet saturated with sucrose. Conversely, the increase from 22.5 to 27.5 could be lesser if the sucrase is near or at saturation point.
Answer:
The maintainance of the lytic and the lysogenic cycle is done by the Cro and the lambda repressor proteins when the number of bacteria is higher than the number of viruses that is the mode of infectivity or MOI the virus under goes the lytic cycle. This is done by the cleaving of the proteins.
So high nutrient concentration in the gut promotes the growth of the E coli that forms a protease that cleaves the Cro protein and causes the activation of the lysis in the bacteria. So in the high nutrient concentration the bacteria is itself responsible for its lysis.
B. transporting oxygen across the cell membrane.
C. breaking down unneeded molecules.

D. taking in wastes from other cells
The correct answer is D. taking in wastes from other cells.
The correct answer is D. taking in wastes from other cells.
Homeostasis is the process by which cells, organisms, or systems maintain stable internal conditions. To achieve and maintain homeostasis, cells perform various processes such as making new molecules for growth, transporting substances across cell membranes, and breaking down unneeded molecules. However, taking in wastes from other cells does not contribute to maintaining homeostasis and is not a recognized process for this purpose.
