Answer:

See explanation

Explanation:

Electroplating involves the coating of one metal on another metal. It is an electrochemical process. The positive electrode is the coating metal while the negative electrode is the metal on which the coating is to be performed.

Since copper is to be coated on an iron nail. A copper plate is made the positive electrode while the iron nail should be the negative electrode.

The electrolyte used in the process should be a copper salt e.g CuSO4 solution.

As electrolysis progresses, the copper electrode(positive electrode or anode) gradually wears away due to the fact that the copper ions are going into the solution and are being deposited on the iron nail.

Abe knew from his anatomy class that there are three different kinds of muscle tissue in the body. He knew lifting weights would

Aleksandr [31]

Answer:

Three different kinds of muscles are -:

SKELETAL MUSCELES
CARDIAC MUSCLES
SMOOTH MUSCLES

Explanation:

SKELETAL MUSCLES -: There are long, cylindrical, and striated skeletal muscle cells. They are multi-nucleated, which means they have more than one nucleus. This is because from the fusion of embryonic myoblasts, they are created. Each nucleus controls the sarcoplasm's metabolic demands around it. There are high energy requirements for skeletal muscle cells, because they contain several mitochondria in order to generate adequate ATP. Examples of skeletal muscles: arms and legs- The muscles that belong to the arms and legs feature in pairs. Abdomen and Back- These muscles are connected to the various sets of skeletal muscles that run across the torso.
CARDIAC MUSCLES -: Cardiomyocytes have a short and narrow outline and are fairly rectangular. They are about 0.02 mm wide and 0.1 mm (millimetres) long, respectively. There are many sarcosomes in cardiomyocytes, which provide the required energy for contraction. Cardiomyocytes usually contain a single nucleus, unlike skeletal muscle cells. Cardiomyocytes, although they contain more sarcosomes, normally contain the same cell organelles as skeletal muscle cells. example - cardiac muscle is present in heart.
SMOOTH MUSCLES -: Smooth muscle cells have a single central nucleus and are spindle-shaped. They range in length from 10 to 600 μm (micrometers), and are the tiniest type of muscle cell. In the expansion of organs like the kidneys , lungs, and vagina, they are elastic and therefore essential. As in cardiac and skeletal muscle, the myofibrils of smooth muscle cells are not aligned, meaning they are not striated, hence the term smooth. example of smooth muscles -: Walls of blood vessels , Walls of stomach , Ureters , Intestines , In the aorta (tunica media layer), Iris of the eye. ,Prostate and Gastrointestinal Tract.

<h2>Upper limb,Pectorial girdle and Axial skeleton</h2>

Explanation:

Upper limb-

The muscles of the upper appendage can be divided into 6 distinct areas such as pectoral, shoulder, upper arm, front lower arm, back lower arm, and the hand
There are 4 muscles of the pectoral locale pectoralis major, pectoralis minor, serratus foremost and subclavius

Pectorial girdle-

The shoulder girdle or pectoral girdle is the arrangement of bones in the attached skeleton which interfaces with the arm on each side
In many of the it comprises of the scapula and clavicle
In many species have three bone found in the shoulder, it connected of the coracoid and clavicle and scapula

Axial skeleton function-

The pivotal skeleton underpins and ensures the mind, spinal rope and huge numbers of the interior organs
It likewise gives locales to the connection of different bones and muscles in the body and shields the nerves and veins from the cerebrum and spinal line.
