Match the following: A) Smooth muscle B) Skin epidermis C) Tendon D) Cardiac muscle 17) Derived from mesenchyme. ___________ 18)
Stolb23 [73]

1.  

17) Derived from mesenchyme. C) Tendon  

Tendon is fibrous connective tissue (made of collagen) that connects muscle to bone.

18) Has a surface to which nothing is attached B) Skin epidermis.  

Epidermis is one of the three skin layers (other two are dermis and hypodermis) of skin that provides a barrier to infection from environmental pathogens.

9) Moves blood through the body. D) Cardiac muscle  

Cardiac muscle is found in heart which pumps blood through the whole body.

20) Moves food through the GI tract. A) Smooth muscle  

Motility through the GI tract is achieved by the contractions of ring smooth muscles (peristalsis).

2.  

21) Smooth muscle. B) Moderate regenerative ability.  

Cells called pericytes are cells that can regenerate smooth muscle cells. Also, smooth muscle cells themselves retain the ability to divide and thus regenerate (increase their own number).

22) Skeletal muscle C) Weak regenerative ability

Skeletal muscle contain  'satellite cells'-stem cells that have the ability to regenerate and repair the damaged fibres.  

23) Cardiac muscle A) Virtually no functional regenerative ability.  

When the cell of cardiac muscle-cardiac muscle cells die, they are not replaced.

24) Areolar connective tissue. D) Regenerates extremely well

Areolar connective tissue is loose connective tissue that hold organs in place. Fibroblasts are cells widely dispersed in this tissue

25) Tendons and ligaments. B) Moderate regenerative ability  

Healing or regeneration of ligaments and tendons can come from the surrounding soft tissues ("extrinsic healing"), or from the ligament /tendon itself ("intrinsic healing").

Organelles such as mitochondria and the endoplasmic reticulum have membranes that compartmentalize reactions and other metabolic
tino4ka555 [31]

Answer:

The correct answer is - they both have highly folded membranes.

Explanation:

Organelles such as the endoplasmic reticulum, Golgi apparatus, and mitochondria have highly folded double membranes. This highly folded membrane provides the increased surface area in the organelle.

As the inner membrane of these organelles is the site for many chemical reactions the highly folded or layered membranes get more space for such reactions to occur due to increased surface area.
