Bess [88]3 years ago
4 0

Answer:

1. the boundary that the ocean crust forms is the Divergent Boundary.

2. both these plates move apart and cause earthquakes.

Explanation:

1. these boundaries are known to crash against each other causing earthquakes, but these boundaries are also form the oceanic crust.

2. when they move apart they cause earthquakes and volcano's. an example of this is the Mid- Atlantic ridge.

Which of the following cause the ventricles to contract?
vovikov84 [41]

Answer:

D. All of the above

Explanation:

In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.

Generally, the cardiac cycle occurs in two (2) stages;

1. Diastole : in this stage, the ventricles is relaxed and would be filled with blood.

2. Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.

Cardiac output can be defined as the volume of blood that is being pumped by the mammalian heart through the left and right ventricle per unit time (minute).

The following conducting systems of the heart cause the ventricles to contract;

I. Atrioventricular (AV) node: it's a component of the electrical conduction system of the mammalian heart located in the Koch triangle which connect the ventricles and atria electrically.

II. Atrioventricular (AV) bundle: it's a specialized tissue that transmits electrical impulse from the atrioventricular (AV) node to the Purkinje fibres of the ventricles.

III. Purkinje fibers: it's a network of specialized cells that comprises of glycogen and they transmit cardiac action potentials in a rapid manner from the atrioventricular (AV) bundle to the myocardium of the ventricles.

Furthermore, the right atrioventricular valve (AV) also referred to as the tricuspid valve is located on the right dorsal side of the human heart. The right atrioventricular valve (AV) comprises of three (3) leaflets (flaps) which opens and closes in order to allow for the flow of blood from the right atrium of the human heart to the right ventricle. Also, the right atrioventricular valve is saddled with the responsibility of preventing blood from flowing backward in the mammalian heart.

Which of the following metabolic pathways is anabolic?
ddd [48]

Photosynthesis

Explanation:

One of the metabolic pathways from the given options is photosynthesis. During catabolism, there is a build up of materials from smaller ones.

  • Metabolism is a process that either involves the building up of materials or the breaking down to release energy.
  • The building up of matter or energy is anabolism.
  • The breaking down is known as catabolism.
  • During the process of photosynthesis, green plants manufacture their food from carbon dioxide and water in the presence of sunlight.
  • The products are glucose and oxygen gas.
  • Energy is stored in the glucose as a chemical form of energy.
  • This is an anabolic process.
  • Respiration, breakdown of actin in muscles and alcohol fermentation are catabolic processes.
