describe peptide bonding and provide an example
Answer:
A peptide bond is a covalent bond formed between two amino acids. Living organisms use peptide bonds to form long chains of amino acids, known as proteins. Proteins are used in many roles including structural support, catalyzing important reactions, and recognizing molecules in the environment. A peptide bond is therefore the basis of most biological reactions. Forming peptide bonds is a requirement for all life, and the process is very similar in all forms of life.
Explanation:
Answer:
peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of other molecules.

A. The reaction rate of the forward reaction would decrease in order to decrease the number of particles.
B. The reaction rate of the forward reaction would increase in order to decrease the number of particles.
C. The reaction rate of the reverse reaction would decrease in order to decrease the number of particles.
D. The rate of the reverse reaction would increase in order to decrease the number of particles.
In this process, with the increase in pressure the chemical equilibrium will shift towards right i.e., the reaction rate of the forward reaction would increase in order to decrease the number of particles. Thus, the correct option is B.
What is Haber's Process?
The Haber process is also known as the Haber–Bosch process. It is an artificial nitrogen fixation process used in laboratories. It is the main industrial procedure used for the production of ammonia on a large scale. It is named after its inventors, Fritz Haber and Carl Bosch, who developed this process in the first decade of the 20th century.
In the Haber process, nitrogen and hydrogen gases react together under the conditions of high temperature i.e., about 450ºC and a high pressure in the presence of an iron or molybdenum which act as catalyst in this reaction.
Therefore, the correct option is B.

type a paragraph describing how the circulatory and respiratory systems work together to deliver oxygen to the body tissue and remove carbon dioxide
The respiratory system brought oxygen to the blood and, by the circulatory system, the oxygen from the blood reaches the heart, and from the heart to the cells.
What is the respiratory system?The respiratory system helps us to respire and reach oxygen to the blood, from there it goes to cells to carry out the process.
The circulatory system circulates the blood to the whole body.
The respiratory system brings oxygen to the blood, and the circulatory system circulates the oxygenated blood to the cells.

Explanation:
The following figure shows a plant cell immediately after it has been placed in distilled water (A) and a plant cell that has been in distilled water for several minutes (B). Determine whether each of the following statements is true or false based on this figure.
Drag True or False to the end of each statement.
Plant cell A has lower water potential than cell B.
Plant cell B is isotonic to the fluid in the beaker.
Plant cell B's water potential increased due to an increase in solutes inside the cell.
Plant cell B is at equilibrium with the fluid in the beaker.
Plant cell A has higher water potential than cell B.
Plant cell A is at equilibrium with the fluid in beaker.
Answer:
Plant cell A has lower water potential than cell B. True
Plant cell B is isotonic to the fluid in the beaker. True
Plant cell B's water potential increased due to an increase in solutes inside the cell. False
Plant cell B is at equilibrium with the fluid in the beaker. True
Plant cell A has higher water potential than cell B. False
Plant cell A is at equilibrium with the fluid in beaker. False
Explanation:
Plant cell A has lower water potential than cell B. True
This statement is true because the water potential of A is -2 bars while that of B is zero bars.
Plant cell B is isotonic to the fluid in the beaker. = True
Isotonic solutions have equal water potential. Since the water potential of distilled water is zero and that of plant cell B is zero as well, plant cell B is isotonic to the fluid in the beaker.
Plant cell B's water potential increased due to an increase in solutes inside the cell = False.
An increase in solute inside the cell doe not increase water potential but rather reduces it.
Plant cell B is at equilibrium with the fluid in the beaker. = True
Plant cell B is at equilibrium with the fluid in the beaker because its water potential is zero since the negative solute potential is counterbalanced by the positive pressure potential.
Plant cell A has higher water potential than cell B = False.
Plant cell A has a lower water potential of -2 bars while plant cell B has a higher water potential of zero.
Plant cell A is at equilibrium with the fluid in beaker. = False.
Plant cell A is not at equilibrium with the fluid in the beaker, rather due to its negative water potential, water will move into the cell.
In humans and other multicellular organisms, which substance plays a central role as an
energy source?
water
fats
O carbohydrates
proteins
Explanation:
Carbohydrates are the main energy source of the human diet.
Fats are also a source of energy but fats are the slowest source of energy.
In humans and other multicellular organisms Carbohydrates plays central role as an energy source.
Carbohydrates are the nutrients most frequently used as an energy source, as they are fast-acting and turn into energy as soon as they are ingested. This energy powers the brain and body.
What are the Carbohydrates?A carbohydrate is a biomolecule consisting of carbon (C), hydrogen (H) and oxygen (O) atoms, usually with a hydrogen–oxygen atom ratio of 2:1.
Carbohydrate is a synonym of saccharide, a group that includes sugars, starch, and cellulose.
The saccharides are divided into four chemical groups: monosaccharides, disaccharides, oligosaccharides, and polysaccharides.
Importance of Carbohydrates:
- Serves as energy store and structural and structural components.
- Backbone of genetic material RNA
- Central to nutrition and found in variety of natural and processed foods.
Cereals, potatoes, fruits, and sugars are rich in carbohydrates.
Fats as an Energy Source:
Fat is an important component of a diet designed to fuel exercise. Fat provides the main fuel source for long-duration, low- to moderate-intensity exercise.
Fat to fuel exercise has three key parts:
Digestion: Fat is slow to digest and be converted into a usable form of energy. This process can take up to six hours.
Transportation: After the body breaks down fat, it needs time to transport it to the working muscles before it can be used as energy.
Conversion: Converting stored body fat into energy takes a great deal of oxygen, which requires decreased exercise intensity.
Protein as an energy source:
Protein is what is known as a macronutrient and is responsible for a large portion of the body's energy supplies.
Only a small amount of protein is directly converted into energy, because it isn't stored away in the body like carbohydrates and fats.
Protein isn't the ideal source for energy but present it in the diet is crucial to maintain high energy levels.
Protein also helps in maintaining muscle mass, which in turn supports a healthy metabolism rate.

what is the process of water moving down through the soil called?
A. evaporation
B. percolation
C. condensation
D. transpiration
Answer:
The answer is B the girl is wright
The process through which the water moves down in the soil is known as percolation. Therefore, option "B" is correct.
What is percolation?The slow movement through a surface that has tiny openings or spaces in it. The tiles prevent water from percolating by sealing off the soil. The value of soil as a crop soil is largely determined by its rate of infiltration which is the rate at which water enters a soil) and percolation (the rate at which water moves through a soil.
These two variables impact the development of normal untamed life environments and the nature and speed of flooding in a given region. The process occurs gradually.
Therefore, the process of percolation is a physical process that helps in water drainage.

Which form of active transport is being shown below?
Answer:
Sodium-Potassium pump, Exocytosis, and Endocytosis are forms of active transport.
Explanation:
We can say the transport is active transport if there is energy used in the transportation of molecules from one place to another. Active transport is a type of transport in which energy is used in the form of ATP for the movement of molecules from one place to another. Forms of active transport are Sodium-Potassium pump, Exocytosis, and Endocytosis. in Exocytosis, cells transport molecules out of the cell by using energy while in Endocytosis, cells absorb molecules from outside by using energy. In Sodium-Potassium pump, the Sodium and Potassium ions are transported by using energy.
