starch, glycogen, and cellulose are all made of chains of AMINO ACIDS?
Glucose is the basic unit of the polymers, starch, glycogen and cellulose. They are made of glucose chains.
What is glucose?Glucose is a carbohydrate monomer and is the basic unit biological polymers such as cellulose and starch. Linkage of a large number of monomers make a polymer such as cellulose , starch etc.
The bond type in each polymer may vary. The linkage of glucose units depends on the conformation of glucose molecules. Glucose can exist in both alpha and beta structure. Both these structure prefer cyclic conformation.
Starch and cellulose is made of alpha-1,4 glycosidic linkage between glucose molecules and glycogen is made of beta-1,4 glycosidic linkage. cellulose polymer contains more glucose units than the other two.
Therefore, starch, glycogen and cellulose are made of glucose chains.

name the process responsible for the formation of glomerular filtrate
Answer: Please refer to:
The process by which glomerular filtration occurs is called renal ultrafiltration. The force of hydrostatic pressure in the glomerulus (the force of pressure exerted from the pressure of the blood vessel itself) is the driving force that pushes filtrate out of the capillaries and into the slits in the nephron.

Certain meteorites have been examined and found to carry samples of which molecules? Select all that apply. lipids nucleotides polypeptides amino acids monosaccharides
The correct answer as to which molecules some examined meteorites contain would be lipids, nucleotides, amino acids, and monosaccharides.
Meteorites are considered to be pieces of rocks or metals that fall into the earth from outer space. These rocks/metals have been extensively studied/analyzed by some researchers, especially those seeking to prove/disprove the Panspermia theory that life originates from other planets.
Several studies conducted found compounds such as lipids, DNA, RNA, and amino acids. There has been no evidence for monosaccharides for a long time until 2019 when an international team discovered sugars such as xylose and arabinose in certain meteorites. No polypeptide has been discovered in meteorites, but its precursor, amino acids, have been discovered.Therefore, the correct answer to the molecules that have been found in some meteorites would be lipids, nucleotides, amino acids, and monosaccharides.

Due to the partial charges on atoms in a water molecule, ____ in water molecules are attracted to oxygen atoms in other water molecules.
Hydrogen bond in water molecules are attracted to oxygen atoms in other water molecules.
A hydrogen bond is a strong dipole-dipole attraction which occurs between:
the hydrogen atom attached to a strongly electronegative atom (for example oxygen in water molecules)another strongly electronegative atom with a lone pair of electronsHydrogen bonding occurs in the following compounds which include water, hydrogen fluoride and ammonia.
When an electronegative atom such as oxygen is bonded to hydrogen, a dipole develops causing the hydrogen to be partially positive while the other atom is partially negative.
Thus, this accounts for high boiling point in compounds that contains hydrogen bonds.

Answer:
Nucleus: blood
Cell Membrane: skin layer
Mitochondria; stomach
Cytoplasm: brain like structure
I'm not really sure of my answers.
Explanation:
The function of nucleus matches with that of brain and the function of cell membrane with that of Golgi bodies. Similarly, the function mitochondria is similar with that of liver and the function of cytoplasm is similar to that of skin.
What is a cell?
Cell is the basic unit of living bodies. A cell contains a nucleus, cell membrane, lysosomes, Golgi bodies etc.
Nucleus regulates all the functions of a cell as brain do in our body. Cell membrane helps to transport ions inside the cell as Golgi bodied do.
Mitochondria provide the energy and produce the chemicals needed for all chemical processes in the cell as liver do in our body.
Therefore, nucleus and brain matches in function and cell membrane and Golgi bodies matches in function. Similarly mitochondria and liver marches as well as cytoplasm and skin matches in functions.

Which of the following mechanisms of change in genefrequencies is responsible for the antibiotic resistance of E. coli in this experiment?
A. founder effect
B. natural selection
C. population bottleneck
D. genetic drift
Natural selection is the mechanism responsible for the antibiotic resistance of E. coli.
Natural selection is a mechanism that favors the adaptation of organisms to survive in their environment, thrive and reproduce.
In the context of antibiotic resistance, antimicrobial substances exert selective pressure on microbes that encourages the evolution of resistance.
Those capable of resisting the effects of antibiotics survive and reproduce, while the vulnerable either die or have their growth inhibited.
The excessive and inappropriate use of antibiotics favors selection for antibiotic resistance in bacteria.
E. coli is characterized by having Gram negative bacilli, it represents the greatest risks of zoonotic transfer of resistance.
In general, and when a treatment is short, there is an elimination of sensitive saprophytic strains of E. Coli and an enormous predominance of resistant strains.
Bacteria also acquire antimicrobial resistance through vertical or horizontal transfer of genetic information.
Therefore, we can conclude that resistance to antibiotics in E. coli is due to the process of natural selection since it evolves to resist the action of an antimicrobial agent.

The graph that correctly shows the nitrogen-fixing bacteria in the soil is graph 2.
Nitrogen-fixing bacteria can be explained as:
Nitrogen-fixing bacteria are the organisms that fix the atmospheric nitrogen into the compounds of nitrogen as ammonia and nitrates.The conversion of the atmospheric nitrogen is done in two steps, the first step involves the conversion of atmospheric nitrogen to ammonia. The second step involves the conversion of ammonium to usable nitrate. Graph 2 represents the amount of atmospheric nitrogen decreasing with an increase in the amount of ammonia. It indicates that atmospheric nitrogen is utilized and converted into nitrogen compounds.

Describe the digestion of fats.
You should include reference to the following in your answer.
- Named regions of the alimentary canal and associated organs.
- Named chemicals, including the end producys of fat digestion.
Answer:
The majority of fat digestion happens once it reaches the small intestine. This is also where the majority of nutrients are absorbed. Your pancreas produces enzymes that break down fats, carbohydrates, and proteins. Your liver produces bile that helps you digest fats and certain vitamins.
Answer:
Triglycerides are large molecules, and unlike carbohydrates and proteins, they're not water-soluble. The digestive process has to break those large droplets of fat into smaller droplets and then enzymatically digest lipid molecules using enzymes called lipases. Digestion of fats mainly take place from fat enzymes produced in liver.

Stage 1 sleep is characterized by a predominance of ________ wave activity in the brain.
Answer: theta
Explanation:
Stage 1 sleep is characterized by a predominance of alpha and theta wave activity in the brain.
The stage of entering the state of sleep is also called stage 1 and is considered as a boundary between the waking state and sleeping.
In this stage, the rhythm alpha predominates, which tends to slow down and show the presence of waves called theta, which are of greater amplitude.
Alpha activity is a pattern that results from a person resting and relaxing.
Theta waves are broad, low-frequency waves that would indicate a state of extreme relaxation and drowsiness.
Eye movements at this stage are slow and muscle tone drops. Phase I is short-lived and occupies about 3-5% of sleep.
Therefore, we can conclude that in stage 1 of sleep the alpha waves would be combined, with a new activity, called theta.
