Muscle cell are richer in lysosomes , as they require lot of energy. correct and rewrite the following statement.

Answers

Answer:

See below

Explanation:

The correct statement is:

=> Muscle cells are richer in mitochondria, as they required lots of energy.

Mitochondrion acts as power house of the cell providing the cell with the required energy.

Correct Statement:-

Muscle cells are richer in Mitochondria, as they require a lot of energy.

[tex] \large{ \underline{ \boxed{ \pink{ \rm{Explanation}}}}}[/tex]

Especially in Skeletal muscles, Mitochondria and glycogen granules are found in abundance. Our limbs that includes our arms and legs shows movement which needs energy. The food is oxidized and energy is released.

More to know:-Mitochondria is popularly known as Power house of the cell or ATP generation site.It is a double-membranous structure with outer membrane smooth and inner membrane surrounds the matrix.The inner membrane have cristae which increase surface area.The cristae bear Oxysomes or F0-F1 particles.Mitocondria is semi-autonomous, it have it's own DNA and ribosomes.

Fatty acids are the building blocks of lipids

WHAT ARE LIPIDS?

Lipids are one of the four major biological molecules in nature (the other three are proteins, carbohydrates and nucleic acids).

Lipids are organic compounds that are generally characterized by their insolubility in water.

MONOMERS OF LIPIDS:

Lipids, like every other biological molecule, are polymeric compounds i.e. they are made up of smaller monomeric units. The monomers that make up lipids are called FATTY ACIDS.

Therefore, fatty acids are the building blocks of lipids.

why is the linner wall of alimantary canal not digisteg although the digestive enzymes can digest all the materials that make cell?

Answers

Answer:

There are no options to this question but it can be answered by giving a general explanation. The answer is:

Because the digestive enzymes are not in direct contact with the cells that make up the walls of the alimentary canal. The walls are protected by mucuous lining.

Explanation:

Digestion of our ingested food is an important process for the effective functioning of our body system. Digestion is the process whereby food, which are usually macromolecules, are broken down into simpler molecules usable by the body. After food is taken in from the mouth (ingestion), it must be broken down by chemical and mechanical means.

The chemicals means is through digestive enzymes, which are proteinous chemical substances. The digestive system consists of the alimentary canal or digestive tract, which is a tube-like organ that forms the path for food passage. Since digestive enzymes secreted during digestion can disintegrate every macro biomolecule e.g protein, carbohydrate etc, it can also break down the molecules that make up the cells of the tract wall.

However, the digestive enzymes does not break down the cells of the canal's wall because the body system secretes mucus, which lubricates the passage of food along the canal. It also prevents the digestive enzymes from coming in contact and acting on the macromolecules that make up the cells of the walls of the alimentary canal.

Answers

Answer:

A mutation occurred in the following DNA sequence AGCCTAGCC and the mutated form is now AGCCTTAGCC. Which of the following correctly describes the result of this mutation?

1.A deletion occurred so all of the amino acids added after the mutation may be wrong.

2.An insertion occurred so all of the amino acids added after the mutation may be wrong.

3.A substitution occurred so all of the amino acids added after the mutation will definitely be wrong.

4.An insertion occurred so all of the amino acids added after the mutation definitely will be different.

Answers

Answer:

Explanation:

1.A deletion mutation occurs when a wrinkle forms on the DNA template strand and subsequently causes a nucleotide to be omitted from the replicated strand.

2.This type of variant results in a shortened protein that may function improperly, be nonfunctional, or get broken down. An insertion changes the DNA sequence by adding one or more nucleotides to the gene.

3. A substitution mutation can cause the following: Change in the coding of amino acids codon to a particular stop codon resulting in an incomplete protein, which is usually non-functional. Can cause Silent mutations where a codon change can encode the same amino acid resulting in no changes in the protein synthesized.

4. when a premature nonsense or stop codon is introduced in the DNA sequence. When the mutated sequence is translated into a protein, the resulting protein is incomplete and shorter than normal. Consequently, most nonsense mutations result in nonfunctional proteins.

Answer:

(a)The strength of natural fibers is very less as compared to synthetic fibers.  Natural fibers are heavy in weight.  Natural fibers can be damaged by moths and other insects.  These fibers are not wrinkle-free.  These fibers are not long lasting and hence not durable.

(b)  Cellulose is termed as polymer because it is made up of many monomer units.

(c) Rayon is first man- made fibre it is known as artificial silk because it have properties that are similar to silk.

(d) Rayon possesses many properties of natural fibers since it is a semi-synthetic fiber. Nylon is a synthetic fiber and has properties that are completely different from natural fibers. The key difference between rayon and nylon is their resistance to wrinkles and tears.

(e) Nylon has since become a popular choice, as it has excellent wind resistance, good elasticity, mildew resistance, and is comparatively cheaper. The material is also lightweight and dries quickly.

(f) When the piece of cotton is burnt then it burns completely and produces no odour or smell. When nylon is burnt, It completely burns and produces burning paper like odour. When nylon is burnt then the nylon is completely shrink and starts to melt first and then produces odour during the time of burning

The lac operon in Escherichia coli Group of answer choices promotes the expression of lactose-utilizing enzymes when lactose is absent from the environment. prevents lactose-utilizing enzymes from being expressed when lactose is absent from the environment. prevents lactose intolerance. prevents lactose-utilizing enzymes from being expressed when lactose is present in the environment.

Answers

Answer:

The correct answer is - prevents lactose-utilizing enzymes from being expressed when lactose is absent from the environment.

Explanation:

The lac operon or the lactose operon is a operon that is essential for the many bacteria like Escherichia coli for metabolism and transport of the lactose.

In the presence of the lactose in the environment of the cell the lac genes are expressed due to the isomer of of lactose called allolactose binds to the Lac repressor protein and do not allow to bind it to lac operator. But in the absence of the lactose, the lactose utilizing enzymes are not expressed  due to repressor bind to the lac operator and prevents the binding of RNA polymerase to the promoter.
