Scientists grow yeast in solutions of varying pH levels to determine the effect of pH on the rate of anaerobic respiration by measuring the quantities of product made by the yeast in each solution. Since yeast typically grow better in acidic environments, the scientists test a pH range of 3-6 with all other conditions held constant. They collect and plot the experimental data in a graph.

Sentence that describes a change in velocity are a moving object gains speed and a moving object changes direction.

Acceleration is that rate at which the speed and direction of a moving object vary over time. A point or object going straight ahead is accelerated when it accelerates or decelerates. Regardless of whether the speed is constant, motion on a circle accelerates because the direction is always shifting.

The primary indicator of both an object's position and speed is its velocity. It is the distance how an object travels in one unit of time. The displacement of the objects in one unit of time is the definition of velocity.

The first 22 pairs of chromosomes are called autosomes.

By international convention, human autosomes, or non-sex chromosomes are numbered in descending order of size from 1 to 22. The exceptions are chromosomes 21 and 22 the former of which is actually the smallest autosome. Sex chromosomes are usually placed at the end of the cardiogram. Twenty-two of these pairs, called autosomes, look the same in males and females.

In the 23rd pair, the sex chromosomes differ between males and females. A female has two copies of her x chromosome, while a male has one of her x chromosome and one of her Y chromosome. The 22 autosomes are numbered by size. Chromosome 1 probably contains 2,000 to 2,100 genes that give instructions for making proteins. These proteins perform different functions in the body. Chromosome 22 contains perhaps 500 to 600 genes that give the instructions for making proteins. These proteins perform different functions in the body.

a. Primary -  peptide bonds.

b. Secondary - hydrogen bonds

c. Tertiary and Quaternary - Hydrogen bonds, covalent bonds and hydrophobic interactions.

Primary Structure: A protein's distinctive and ordered amino acid sequence is known as its primary structure. It describes the order in which amino acids are added to a polypeptide as it develops during translation. There are essentially an endless number of fundamental sequences with 20 distinct amino acids.

Secondary  Structure -  It is one where there is a polypeptide chain's that consistent local patterns of coils or folds.

Tertiary Structure : It has a polypeptide's general three-dimensional form as a result of interactions between the R groups of the amino acids that make up the chain.

Lastly, Quaternary Building: It is the form that is produced when two or more polypeptide subunits come together.

When a protein source reaches your stomach, hydrochloric acid and proteases enzymes convert it into smaller chains of amino acids.

Peptides, that are broken down by proteases, are also what link amino acids. These smaller chains of amino acids go from your tummy to your small bowel.

However, protein is broken down into ketone bodies to be utilised for energy if the body is not acquiring enough calories from other foods or from the fat stored in the body. The body breaks down excess protein and stores its constituent parts as fat if it is ingested.

Consumed protein is converted to amino acids by the body and then absorbed. It is utilised in the development of muscles and organs, the production of hormones and antibodies, the storage of fat, and the production of energy.

The small intestine is where protein digestion finishes after starting in the stomach. A stomach enzyme called pepsin starts the breakdown of proteins.

Cellular components are divided using a process called cell fractionation that keeps each component's unique functions intact.

Chromatographic and electrophoretic techniques can also be used to separate proteins into different fractions. By using adsorption chromatography and/or gel filtration, which separates proteins based on their size and shape, different proteins can be separated.

The best technique for isolating organelles is centrifugation. Other methods that take advantage of different physical (such as electrical charge for free flow electrophoresis) or biological (such as ligand affinity for immunoisolation) characteristics have also been used to study complex organelles and membranes.

Each replication cycle results in an incomplete replication of the DNA near the extreme end of the chromosome, gradually shrinking the chromosome.

Eukaryotes have linear, rod-shaped chromosomes that have ends as opposed to bacteria, which have circular chromosomes. DNA replication is difficult as a result of these ends. Each replication cycle results in an incomplete replication of the DNA near the extreme end of the chromosome, gradually shrinking the chromosome.

Telomeres shorten as a result of regular DNA polymerases' incomplete copying of linear DNA molecules during cell division. The end replication problem is the name given to this [6]. The process of resection and fill-in that occurs during the synthesis of the telomere leading-strand is mostly to blame for this.

The creation, modification, and shipping of proteins that are released from the cell happens in Rough Endoplasmic Reticulum (RER) and Golgi Apparatus organelle(s) found in large quantities in hormone and enzyme-producing cells of the pancreas.

Rough Endoplasmic Reticulum  (RER) are have ribosomes attached to their outer membrane. These ribosomes are referred to as the protein manufacturing place of a cell. The ribosomes are the site where tRNA brings amino acids to code with the mRNA so that proteins can be produced. Hence, the creation of proteins occurs in the Rough Endoplasmic Reticulum  (RER) of a cell.

The proteins, after creation, are sent to the Golgi apparatus which carry out the function of modification and transport of proteins. Without post-translational modifications, a protein will not be able to travel outside of the cell.

The cell membrane also called the plasma membrane is found in all cells and separates the interior of the cell from the external environment. The cell membrane consists of a semi-permeable lipid bilayer.

Cell membranes regulate the transport of substances in and out of cells. The cell surface structure can be viewed as a three-layered structure with the central plasma membrane having certain macromolecular components attached to the outside exoskeleton and other components to the inside membrane cell skeleton.

The outer covering of eukaryotic cells is called the plasma membrane. This membrane is responsible for isolating and protecting the cell from the environment and is mainly composed of a bilayer of molecules such as proteins lipids, and fats. Cell membranes are made up of proteins and lipids. This is because it is mainly made up of lipids. Only certain substances can penetrate. Phospholipids are the most abundant lipid type in membranes.

Volcanic eruptions are the expulsion of magma and gases from the interior to the exterior of the Earth. They are caused by plate interaction in the crust and changes in magma and pressure in the mantle.

A volcanic eruption is an expulsion of material rising from the Earth's interior toward the surface. It is an event that occurs when hot magma generated in the Earth's interior rises along the volcano, together with gases that increase the pressure until it emerges to the exterior.

Volcanic eruptions are related to tectonic plate movements. These plates interact and produce new magma by melting solid material. These interactions produce changes in tectonic plates, magma movements, and pressure in the Earth's interior, which is directed to the cortex -the outermost layer-.

The elevated temperatures, and the increase in pressure and magma changes, make it rise toward the surface moving along the volcano until emerging to the exterior. This is how the Erth interior and exterior pressures are equilibrated again.

Let us remember that,

Volcanic eruptions increase gases concentration in the exterior, and is a natural cause of atmospheric pollution.
