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:
The number of hydrogen bonds involved will be 39
Explanation:
There are 4 types of bases that exist in a DNA, which are adenine, thymine, guanine and cytosine. Double stranded DNA molecules have these bases attaching specifically to one another; adenine only binds to thymine and vice versa while guanine only binds to cytosine and vice versa. These two bases bonding together are referred to as base pairs and the type of bond here is the hydrogen bond. There are double bonds between the adenine and thymine base pair while there are triple bonds between the guanine and cytosine base pairs.
Thus, when there are 13 cytosine bases in a DNA molecule, the number of hydrogen bonds present in the resulting base pairs will be 13 × 3 (because cytosine binds with a triple bond to guanine).
13 × 3 = 39
The number of hydrogen bonds involved will be 39
So, in a DNA molecule of 50 base pairs that contains 15 cytosine (C) bases, there would be a total of 115 hydrogen bonds involved in base pairing.
In DNA, base pairing occurs between complementary nitrogenous bases. Adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). Each base pair is connected by hydrogen bonds.
In a DNA molecule of 50 base pairs with 15 cytosine (C) bases, you can determine the number of hydrogen bonds involved in base pairing as follows:
1. Each adenine (A) pairs with thymine (T) and forms two hydrogen bonds.
2. Each cytosine (C) pairs with guanine (G) and forms three hydrogen bonds.
So, for the 15 cytosine (C) bases, you would have 15 pairs of C-G base pairs, and for the remaining 35 bases, you would have 35 pairs of A-T base pairs.
Total hydrogen bonds involved in base pairing:
(15 pairs of C-G base pairs * 3 hydrogen bonds per pair) + (35 pairs of A-T base pairs * 2 hydrogen bonds per pair)
= (15 * 3) + (35 * 2)
= 45 + 70
= 115 hydrogen bonds.
So, in a DNA molecule of 50 base pairs that contains 15 cytosine (C) bases, there would be a total of 115 hydrogen bonds involved in base pairing.

Answer:
The correct order would be:
b. "Unwind the DNA molecule near the promoter."
d. "Transcribe the complementary RNA strand."
c. "Exit the nucleus to the cytoplasm."
a. "Combine the mRNA strand with a ribosome and a tRNA carrying a methionine."
The given order is according to the central dogma of a cell. According to central dogma DNA is first transcribed into mRNA which is then moved out of nucleus (in eukaryotic cells).
For transcription, the DNA is unwind near the promoter region where transcription factors and RNA polymerase binds the template strand. It then make mRNA which is moved out of the nucleus.
The mRNA then is translated with the help of ribosome and tRNA. The start codon in mRNA usually codes for methionine due to which tRNA carrying methionine recognises the start codon and initiate the process of translation.
Answer:
Glycogen.
Explanation:
Carbohydrates are the one of the most important bio molecules present in the living organisms. The carbohydrates are the polymers of the sugars that are linked through the glycosidic bonds.
The carbohydrate is stored in the form of starch in plants. The animals carbohydrates is stored in the form of glycogen. The sugars units are linked through the alpha glycosidic bonds with both the linear and branched chain structure.
Thus, the answer is glycogen.
a. decreased portions sizes in restaurarts and movie theaters.
b. increased use of personal vehicles, telephones, and computers.
c. increased number of meals eaten outside the home
Answer:
c. increased number of meals eaten outside the home
Explanation:
Environment is the surrounding of living organism, where he gets to survive by meeting its needs.
Environmental factors are factors in the environment that are associated to growth and development example is temperature.
The environment an individual stays have a great influence on the physical expression and character of the individual.
For a fat person the environment had played out his role which should be controlled to achieve a significant weight loss. Increasing number of meals eaten outside the house is one major factor that would not allow such individual to loose weight. Intake of food should be greatly controlled and watched to achieve weight loss.
Answer:
Global climate models usually work by managing the planet as a set of connected boxes because this facilitates the management of the calculations applied in a climate system that is dynamic, variable and complex, which is due to the fact that there is not an equal pattern of climate in each area of the planet.
Explanation:
Climate models have been designed to show the dynamics of the planet's climate and what can be expected from the changes that occur in the future.
The scientific basis of a climate model is physical phenomena and chemical reactions to which a series of differential calculations are applied to determine the behaviour of:
Global climate models usually divide the planet into sections -such as boxes- making the calculations in each sector, as well as the interaction of each section with the adjacent sections, which greatly facilitates making the differential calculations, showing the climate at a given time and making predictions of future climate behavior.
It is important to mention that a climate model also explains the changes that occur in the climate due to human activity, which is different in each region of the world.
