What is cellulose ?
Cellulose is a complex unbranched kind of glucose, a residue polymer formed via beta-1,4 glycosidic connections. It has a chemical formula (C6H10O5)n.
This chiral organic compound is tasteless, odor less, water-soluble and biodegradable.
There are huge application of cellulose in different sectors like paper, textiles, pharmaceuticals, and insulation.
The major classification are monosaccharides which can not be hydrolyzed into simple polyhydroxy aldehydes or ketone units for example glucose, fructose etc.
Oligosaccharides release 2 to 10 monosaccharide units after hydrolysis like Sucrose, maltose.
Polysaccharides are joined by a large number of monosaccharides by glycosidic bond such as starch, cellulose, glycogen.
Three types of major polysaccharides are starch main storage of plants, a polymer of alpha- Glucose and have amylose and amylopectin.
Glycogen are the main storage in animal body and their structure is similar to amylopectin.
Thus option D is correct.

Lyme disease is spread by ticks that attach to an animal to feed. Which describes the role of the tick?
Lyme disease is spread by ticks that attach to an animal to feed, and ticks play a critical role in the transmission of Lyme disease, as ticks are external parasites that feed on the blood of animals, including humans, and can transmit infectious diseases as they feed; this is option C.
What is a tick?When an infected tick attaches itself to an animal, it can transmit the bacterium responsible for Lyme disease, which is called Borrelia burgdorferi. The bacterium is typically present in the tick's saliva, and it can be transmitted to the animal as the tick feeds on its blood. Once the bacterium enters the animal's bloodstream, it can spread throughout the body and cause a range of symptoms, including fever, headache, fatigue, and a characteristic bullseye rash. Ticks play a critical role in the transmission of Lyme disease because they serve as both a vector and a reservoir for the bacterium.
Hence, ticks play a critical role in the transmission of Lyme disease, as ticks are external parasites that feed on the blood of animals, including humans, and can transmit infectious diseases as they feed; this is option C.

Proteins are one of the substances produced by cells. Which organelle is responsible for storing the genetic information responsible for the production of proteins?
A. nucleus
B. lysosome
C.Golgi apparatus
D.endoplasmic reticulum
Answer:
b
Explanation:
The organelle that is responsible for storing the genetic information responsible for the production of proteins is nucleus. The correct option is A.
What is nucleus?A nucleus is the membrane-enclosed organelle inside a cell that residences the chromosomes in genomics.
The nuclear membrane includes a collection of holes or pores that allow specific molecules to pass further and leave the nucleus.
The nucleus regulates and controls the activities of the cell and contains the genes, which contain hereditary information.
Ribosomes in eukaryotes receive protein synthesis orders from the nucleus, in which sections of DNA are transcribed to produce messenger RNAs (mRNAs).
An mRNA is transported to the ribosome, that also uses the information contained within it to construct a protein with a specific amino acid sequence.
Thus, the correct option is A.

Modify the existing vector's contents, by erasing the element at index 1 (initially 200), then inserting 100 and 102 in the shown locations. use vector adt's erase() and insert() only, and remember that the first argument of those functions is special, involving an iterator and not just an integer. sample output of below program:
Answer:
Following are the code to this question:
#include <iostream>//defining header file
#include <vector>//defining header file
using namespace std;
void PrintVectors(vector<int> numsList)//defining a method PrintVectors that accept an array
{
int j;//defining integer variable
for (j = 0; j < numsList.size(); ++j)//defining for loop for print array value
{
cout << numsList.at(j) << " ";//print array
}
cout << endl;
}
int main()//defining main method
{
vector<int> numsList;//defining array numsList
numsList.push_back(101);//use push_back method to insert value in array
numsList.push_back(200);//use push_back method to insert value in array
numsList.push_back(103);//use push_back method to insert value in array
numsList.erase(numsList.begin()+1);//use erase method to remove value from array
numsList.insert(numsList.begin(), 100);//use insert method to add value in array
numsList.insert(numsList.begin()+2, 102);//use insert method to add value in array
PrintVectors(numsList);//use PrintVectors method print array value
return 0;
}
Output:
100 101 102 103
Explanation:
In the above-given code, inside the main method an integer array "numList" is defined, that use insert method to insert value and use the erase method to remove value from the array and at the last "PrintVectors" method is called that accepts a "numList" in its parameter. In the "PrintVectors" method, a for loop is declared, that prints the array values.
How could a mutation or change in a DNA sequence impact the overall function of a cell?
Answer:
DNA is a dynamic and adaptable molecule. As such, the nucleotide sequences found within it are subject to change as the result of a phenomenon called mutation. Depending on how a particular mutation modifies an organism's genetic makeup, it can prove harmless, helpful, or even hurtful.

photosynthesis stage?
SELECT ALL THAT APPLY
a Water is split.
b Oxygen gas is released.
C NADPH and ATP are used.
d NADPH and ATP are produced.
Answer:
A, B and D
Explanation:
Answer and you’ll see.
Plants and other living things employ a process called photosynthesis to transform light energy into chemical energy that can then be released through cellular respiration to power the organism's activities.
What key things happen in the photosynthesis stage's light reaction?When chlorophyll absorbs light energy during the light-dependent stage ("light" reactions), some electrons in the pigment molecules are excited to higher energy levels; these electrons then leave the chlorophyll and pass through a series of molecules, resulting in the formation of NADPH (an enzyme) and high-energy ATP molecules.
The light processes convert solar energy into chemical energy, which is then stored in NADPH and ATP molecules. As a byproduct of the light processes, oxygen gas is also released.

Enzymes involved in the breakdown of fats contribute to the reaction in which way? These enzymes -
O eliminate toxins produced by the reaction.
O increase the speed of the reaction.
O are completely consumed during the reaction.
O reduce the reactants needed for the reaction.
Answer:
...enzymes increase the speed of the reaction
Explanation:
In biological systems, enzymes are proteins that mediate chemical reactions. They increase the rate of chemical reactions, by lowering the activation energy, required for the reaction (eg. hydrolysing a bond) to occur.
Enzymes require the aid of cofactors, inorganic molecules to act as complements to enzymes. They cause structural changes that result in substrate recognition and binding. Here they act by breaking down large fat molecules into fatty acids and lipids.

An ant and a stone are on a circular disc, which is rotating at a constant speed. The stone is fixed to the disc. The ant is moving along the rim in the opposite direction and at the same speed as that of the disc. Which of these shows the position of the ant and the stone after the disc completes 3/4th of a revolution?
Find attached the options
Answer:
The option B in the attached is correct
Explanation:
In the given scenario the ant and stone are on the same disc and the stone is fixed.
The disc is moving at a constant speed in a clockwise direction while the ant is moving in the opposite direction.
The starting position is also attached with the ant opposite the stone.
So for a full rotation the ant would have gone round and met up with the stone.
If the disc completes a 3/4th revolution it will be at the position in B. The ant would have gotten to the stone by half revolution, and by 3/4th revolution it would have gone a quarter of the disc from the stone as shown
