Study the pedigree chart. ( picture above)
Which of these can be determined about the trait based on this chart?
○ The trait is recessive. the parents of A were both carriers
○ The trait is recessive. The parents of A were both affected
○ The trait is dominant The parents of te were both affected.
○The trait is dominant The parts of A were both carriers
Answers
Answer: The trait is recessive. the parents of A were both carriers
Explanation: The correct answer should be the trait is recessive.
Since we can only see A mothers tree and she is not affected by the trait she is a carrier.
Unfortuately, the tree does not show her father's side of the tree so we can only "assume" based on the options that he also is a carrier of the trait.
So answer it will be "The trait is recessive. the parents of A were both carriers"

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.

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),
Chromosomes condenseBegins the formation of the spindle apparatus from cytoskeleton present in the cytoplasmThe homo-logous chromosomes pair and crossing over occurs. Crossing over refers to the interchange of genetic material between non-sister chromatids.During metaphase I,

Answers
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.

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.
