Explanation

The link reaction (pyruvate to acetyl-CoA), Kreb's cycle (citric acid cycle), and the electron transport chain all occur in the mitochondria.

Explanation

Discoloration of skin after death is liver (livor) mortis (also known as postmortem hypostasis).

It occurs due to the settling of blood in the lower parts of the body.

It causing a reddish-purple discoloration.

Explanation

The type of research focused on finding a solution to an immediate practical problem is termed applied research.

It aims to address specific, real-world issues by developing practical solutions.

Explanation

It is mandatory to wear a safety helmet when rescuing under falling materials.

This protects the rescuer from head injuries caused by falling debris or other hazardous materials.

Explanation

Being careful can help to stay away from accidents.

By being vigilant and attentive to your surroundings, you can avoid many potential hazards. This involves:

• Paying attention to what you're doing.
• Avoiding distractions, especially when performing tasks that require focus, like driving.
• Following safety guidelines and procedures.
• Being aware of your environment and anticipating potential dangers.

Explanation

The muscles that never fatigue are the heart muscle (cardiac muscle)

Cardiac muscle has more mitochondria than skeletal muscle (up to 35% compared to 1-2%), Which makes it resistant to fatigue.

Mitochondria are essential for generating ATP, the cell's energy source.

Other muscles, such as skeletal muscles, can experience fatigue and failure under strenuous conditions.

Explanation

The red blood cell survives on average only 120 days.

Red cells contain a special protein called hemoglobin

RBCs' function is to carry oxygen from the lungs and deliver it throughout the body.

They are made in the bone marrow.

Additional information:

The lifespan of white blood cells is 12-20 days. 

They boost the immune system.

Explanation

• During Anaphase, the contraction of spindle fibers takes place, resulting in the separation of sister chromatids and their movement towards opposite poles of the cell.
• This stage is characterized by the pulling apart of the sister chromatids, ensuring each daughter cell receives a complete set of chromosomes.

Explanation

• Anaerobic respiration is a process of cellular respiration that occurs in the absence of oxygen (O2).
• It is used by small microorganisms like fungi and bacteria, as well as muscle cells during intense exercise.
• Anaerobic respiration produces less energy than aerobic respiration and typically results in the production of lactic acid or ethanol and carbon dioxide.

Explanation

A foliose lichen is a lichen with flat, leaf-like lobes.

They are generally not firmly bonded to the substrate on which they grow.

It is one of the three most common growth forms of lichens.
