Explanation

If the students do not understand the lesson, the teacher's responsibility is to explain the lesson again.

Teachers can use different strategies to explain the concept.

A teacher must not leave the concept unexplained if students fail to understand it.

Explanation

Spondylosis affects the vertebral joints.

Spondylosis is a term used to describe degenerative changes in the spine

Particularly in the vertebral joints and intervertebral discs.

It involves the breakdown of the cartilage and the formation of bone spurs in the spine

Which can lead to pain, stiffness, and decreased mobility. 

Explanation

Carotenoids serve multiple functions in plants:

Broaden Spectrum of Light:

• Carotenoids can absorb light energy in the blue and green regions of the spectrum,
• thereby expanding the range of light wavelengths that can be used for photosynthesis.

Provide Yellow Color to the Plants:

• Carotenoids are responsible for the yellow, orange, and red colors observed in many fruits, flowers, and vegetables.

Protect Chlorophyll by Absorbing Excessive Light:

• Carotenoids act as photoprotective agents by dissipating excess energy that chlorophyll molecules cannot handle,
• thus protecting the photosynthetic machinery from damage caused by excessive light exposure.

Explanation

Opportunity means:  موقع

closure means: بندش

Explanation

Language is not typically considered one of the elements of active learning.

Language plays a crucial role in facilitating communication, comprehension,

The elements commonly associated with active learning are:

• manipulation
• practical engagement
• materials.

Explanation

Enterokinase, also known as enteropeptidase, is an enzyme produced by cells lining the duodenum in the small intestine.

It plays a crucial role in the digestion of proteins by activating trypsinogen, an inactive precursor of trypsin.

Once trypsinogen is activated by enterokinase,

it can then activate other pancreatic zymogens and initiate the digestion of proteins in the small intestine.

They typically reside in the colon and rectum of humans and can cause itching around the anus, especially at night.

Explanation

Intermediate filaments have a diameter of about 10 nm,

Which is intermediate between the diameters of the two other principal elements of the cytoskeleton:

1. actin filaments (about 7 nm) 
2. microtubules (about 25 nm).

Additional informational:

The intermediate filaments are not directly involved in cell movements.

They appear to play a structural role by providing mechanical strength to cells and tissues.
