Answer:

Flexor Group- group of five muscles mainly in charge of movements of forearm, hand and fingers.

Peroneal Group- these muscles play a role in the movements of the ankle joint  and support of the foot.

Hamstring Group- The hamstrings are a group of muscles and their tendons at the rear of the upper leg. They include the biceps femoris, semitendinosus, and semimembranosus. The hamstrings flex the knee joint and extend the thigh to the back side of the body.

Gluteal Group- The gluteal muscles are a group of three muscles which make up the buttocks: the gluteus maximus, gluteus medius and gluteus minimus. The three muscles originate from the ilium and sacrum and insert on the femur.

Quadricep Group- The Latin translation of 'quadriceps' is 'four headed,' as the group contains four separate muscles: the vastus lateralis, vastus medialis, vastus intermedius, and the rectus femoris. Each of the vastus muscles originates on the femur bone and attaches to the patella, or kneecap.

Extensor Group- The superficial extensors of the forearm are a group of six muscles situated in the superficial posterior compartment of the forearm. These muscles include the brachioradialis, extensor carpi radialis longus, extensor carpi radialis brevis, extensor digitorum, extensor carpi ulnaris  and extensor digiti minimi.

Sartorius Group- couldnt  find anything

Adductor Group- The adductors are a group of muscles, as the name suggests, that primarily function to adduct the femur at the hip joint. Although they are all located somewhere along the medial side of the thigh, they originate in different places at the front of the pelvis.

Naddik [55]
An open fracture is most accurately defined as a fracture in which the overlying skin is no longer intact. A fracture is normally the break in the continuity of the bone. It is also called a compound fracture, in which  the fracture is an open wound or break in the skin near the site of the broken bone. Immediate treatment for an open fracture focuses on preventing infection at the site of the injury.

Boats are able to stay afloat because of the force caused by...
Ugo [173]

Answer:

d) buoyancy

Explanation:

Buoyancy can be defined as an upward force which is created by the water displaced by an object.

According to Archimede's principle, it is directly proportional to the amount (weight) of water that is being displaced by an object.

Thus, the greater the amount of water an object displaces; the greater is the force of buoyancy pushing the object up.

The buoyancy of an object is given by the formula;

Fb = pgV

But, \; V = Ah

Hence, \; Fb = pgAh

Where;

Fb = buoyant force of a liquid acting on an object.

g = acceleration due to gravity.

p = density of the liquid.

v = volume of the liquid displaced.

h = height of liquid (water) displaced by an object.

A = surface area of the floating object.

The unit of measurement for buoyancy is Newton (N).

Additionally, the density of a fluid is directly proportional to the buoyant force acting on it i.e as the density of a liquid decreases, buoyancy decreases and vice-versa.

Boats are able to stay afloat because of the force caused by buoyancy. This simply means that, a boat is able to float because the volume of water it displaces weigh more than its own weight. Thus, if a boat or any physical object weighs more than the volume of water it displaces, it would sink; otherwise, it floats.

Which fossils provide information as to the mode of formation of an oxygen-rich atmosphere by about 2 billion years ago?
Oksanka [162]

Answer:

The fossils that provide information on the formation of an oxygen-rich atmosphere are the stromatilites from the Precambrian era. These are layered and columnar fossils consisting mainly of cyanobacteria which were the original life form back then. These bacteria took in carbon dioxide and produced oxygen by photosynthesis as early as 2.5 billion years ago (the earth is about 4.5 billion yrs old).
