Answer:
C. CH4 + 202 – CO2 + 2H20
Explanation:
CH4+O2-CO2+H20
The above equation represents combustion of methane to produce carbon-dioxide and water.
One carbon atom is present on the reactant side as well as on the product side. Four hydrogen atoms are present on the reactant side and two hydrogen atoms on product side. In order to balance this equation, we would multiply water molecule by two. Now there are four atoms of oxygen in the product side but only two on reactant side, so we will multiply oxygen molecule by two on the reactant side. Now the equation is balanced.
The balanced chemical equation is:
CH4+202-CO2+2H2O
This equation obeys the law of conservation of mass as the mass of the reactants is same as that of the products.
Answer:
C. CH4 + 202 – CO2 + 2H20

Vhich molecules store information related to the function of a cell in the form of a coded message!
A
nucleic acids
B
lipids
C
enzymes
D
carbohydrates
Answer: The correct answer is A. nucleic acids.
Explanation: The genetic information is stored in the form of nucleic acids i.e. deoxyribonucleic acids (DNA) or ribonucleic acids (RNA).
Nucleic acids are large macromolecules in cells and viruses. Nucleic acids store and express genetic data. Therefore, option (A) is correct.
What are nucleic acids?The biopolymers and macromolecules known as nucleic acids are fundamental to every known type of living being. Nucleotides, which are the monomers that make up nucleotides, are composed of a 5-carbon sugar, a phosphate group, and a nitrogenous base. They are the building blocks that make up nucleotides. Deoxyribonucleic acid and ribonucleic acid are the two primary subgroups that can be found among nucleic acids.
Nucleic acids, including deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), are responsible for carrying genetic information. This information is read in cells and used to produce RNA and proteins, which are necessary for the functioning of living things.

Construct the correct sequence of events for meiosis I, starting at the top.
1. Separated homologues cluster at each pole.
2. Paired homologues align at the equator, microtubules attach to kinetochores of sister chromatids.
3. Microtubules shorten, chiasmata are broken, homologous chromosomes are pulled to opposite poles.
4. Nuclear envelope re-forms around each daughter nucleus.
5. Chromosomes condense, forming of spindle apparatus begins, homologous chromosomes pair and crossing over occurs.
The sequence of events in meiosis I is first 'chromosomes condense and crossing over occurs', second 'paired homologues align at the equator', third 'chromosomes are pulled to opposite poles', fourth 'separated homologues cluster at each pole' and fifth 'nuclear envelope re-forms around each daughter nucleus'.
Meiosis is a reductional cell division by which a parent cell produces four daughter cells with half of the genetic material.
Meiosis can be divided into meiosis I and meiosis II.
During prophase I (meiosis I),

Skeletal muscle exhibits alternating light and dark bands called a sarcomere
Skeletal muscle is having sarcomere having myofibrils which appear dark and light in the microscope.
What is skeletal muscle?Only thin filaments containing actin are present in isotropic bands, anisotropic bands are the darker bands (A bands).
Repeating sarcomere sections, which are visible under the microscope as alternating dark and light bands, make up myofibrils.
When a muscle contracts or relaxes, long, fibrous protein filaments called sarcomeres glide past one another. Because of this, skeletal muscle is also known as striated muscle.
Therefore in appearance due to myofibrils composed of the sarcomere look light and dark bands in the skeletal muscle under a microscope.

Answer:
What muscle is below the deltoid and is attached to the ulnar process? How many heads does this muscle have?
Explanation:
Triceps is the muscle that is responsible for the extension of elbow joint and also contribute to extension of shoulder joint. This muscle have three origin, that's why the name triceps. The triceps muscle has three heads which are:
A. The long head originates from the infraglenoid tubercle of scapula.
B. The lateral head originates from above the radial Grove in humerus.
C. The medial head originates form below the radial Grove in humerus.
These heads meet to form the body of triceps which gets inserted as triceps tendon in the olecranon process of ulna just behind the elbow. The contraction of this muscle causes the extension of the elbow joint.
Deltoid muscles are in your shoulder, which is the ball-and-socket joint that connects your arm to the trunk of your body. Deltoid muscles help you move your arms in different directions.
What is Deltoid muscle?The muscle known as the triceps is in charge of extending the elbow joint and helping to extend the shoulder joint. The name triceps refers to the fact that this muscle has three origins.
The scapula's infraglenoid tubercle is the source of the long head. In the humerus, the lateral head develops from above the radial Grove. In the humerus, the medial head develops from below the radial grove.
The triceps body is formed when these heads come together, and it is placed as the triceps tendon in the ulna's olecranon process, right beyond the elbow. The elbow joint extends as a result of this muscle contracting.
Therefore, Deltoid muscles are in your shoulder, which is the ball-and-socket joint that connects your arm to the trunk of your body. Deltoid muscles help you move your arms in different directions.
