Hint: The wall which is present at the outermost of the cell wall acts as a glue between the different cells. . The secondary wall is not present in every cell, it is present in few cells that alter the growth of the primary wall.
Complete answer:
A cell wall is an outer structural layer present in only some types of cells, just outside the cell membrane. It is usually tough, flexible, and sometimes rigid. The cell wall is mostly composed of two layers and sometimes three layers too. The layers of the Cell wall are as follows-
- The primary cell wall is generally a flexible thin, and an extensible layer formed while the cell is growing i.e not fully developed. It is usually made up of cellulose and it is often permeable too.
-The middle lamella, a layer rich in pectins. It is the outermost layer that forms the interface between adjacent plant cells and glues them together.
-The secondary cell wall, if present, is a thick layer formed inside the primary cell wall after the cell is mature. it's not found in all cell types.
Additional Information: The cell wall is majorly composed of the cellulose microfibrils that are linked via hemicellulosic tethers to form the cellulose-hemicellulose network, which is embedded in the pectin matrix. The most common hemicellulose present in the primary cell wall is xyloglucan.
The outer part of the primary cell wall of the plant epidermis is mostly covered with the cutin and wax, forming a permeability barrier known as the plant cuticle.
Secondary cell walls contain a wide range of additional compounds that helps to enhance and modify their mechanical properties and permeability. The major polymers that make up wood (largely secondary cell walls) include cellulose, 35-50% .xylan, 20-35%, a type of hemicellulose, and lignin, 10-25%.
The cell wall which is the farthest from the plasma membrane in plants is the primary cell wall.
What do you mean by Cell wall?A Cell wall may be defined as a specialized form of the extracellular matrix that surrounds every cell of a plant. It is made up of cellulose.
The primary cell wall is the outermost cell wall in the plants, while the secondary cell wall is the innermost cell wall in the plant cell.
The secondary cell wall is located near the plasma membrane, while the primary cell wall is located farthest from the plasma membrane.
Therefore, the cell wall which is the farthest from the plasma membrane in plants is the primary cell wall.

(ii) Conversion of light energy to chemical energy and splitting of water molecules into hydrogen and oxygen.
(iii) Reduction of carbon dioxide to carbohydrates.
I expect that this might help you out.
Explanation: The process of Photosynthesis is simple.
The three events that take place in "Photosynthesis", are:
1. Absorption of light energy by chlorophyll.
2. Conversion of light energy to chemical energy and splitting of water molecules into hydrogen and oxygen.
3. Reduction of carbon dioxide to carbohydrates.
Definition of Photosynthesis: The process by which plants and other organisms use sunlight to synthesize foods from carbon dioxide and water.

In a bacterium that possesses antibiotic resistance and the potential to persist through very adverse conditions, such as freezing, drying, or high temperatures, dna should be located within, or be part of, which structures?.
In a bacteria that possesses antibiotic resistance and the potential to persist through very adverse conditions, the DNA should be located in the plasmid.
What is a plasmid?Plasmid is a small, extrachromosomal DNA molecule within a cell that is independent of the chromosomal DNA and can replicate on its own.
The plasmid usually contains extra genes that codes for resistance and other specific traits.
Therefore, it can be said that in a bacteria that possesses antibiotic resistance and the potential to persist through very adverse conditions, the DNA should be located in the plasmid.

There are how many types of nitrogenous bases?
Answer:
4
Explanation:
There are 4 nitrogenous bases and they are Adenine, Thymine, Cytosine and Guanine (in RNA, Thymine is replaced by Uracil)
Answer:
Four different types of nitrogenous bases are found in DNA: adenine (A), thymine (T), cytosine (C), and guanine (G).
Explanation:
DNA is a polynucleotide. Each nucleotide is made up of deoxyribose sugar, a phosphate group and nitrogenous base. In DNA, there are four main kinds of nitrogenous bases. Adenine (A), guanine (G), thymine (T), and cytosine (C) are the four bases of DNA (C). Purine bases are adenine and guanine, whereas pyrimidine bases are thymine and cytosine. Base pairing occurs between complementary bases on two strands of double-stranded DNA. By two and three hydrogen bonds, A and G link with T and C, respectively. In RNA, uracil is present instead of thymine.

As a result of the general stress response, blood concentrations of epinephrine.
Answer:
THE STRESS RESPONSE. Increased concentrations of cortisol, glucagon, and epinephrine serve to increase blood glucose levels and to redirect metabolism so as to increase concentrations of fuel substrates. Finally, there appears to be a tendency towards hypercoagulability, which would likely improve hemostasis.
Explanation:
Dose this help you?
As a result of the general stress response, blood concentrations of epinephrine and cortisol rise.
What metabolic changes occur during the stress response?When the body is under stress, the hormone cortisol, stress and steroid, is released. As a result, the body's sugar level rises, and the extra sugar aids in tissue healing.
Adrenaline is another name for epinephrine. It is a hormone used in medication. When the body experiences an emergency, this is released. When something unexpected happens, like getting stung or bitten by a dog, taking medicine, etc.
They come with charges that include faster heartbeats, higher blood sugar, and improved accuracy.
Therefore, blood concentrations of epinephrine and cortisol increase during the stress response.
