Explain this diagram?????????​
Simora [160]

Answer:

the diagram explains the process of DNA digestion and DNA ligation, which is usually used in molecular cloning techniques  

Explanation:

Molecular cloning can be defined as the process used to synthesize multiple copies of a particular DNA fragment. Molecular cloning requires the insertion of a foreign DNA fragment into an appropriate vector (e.g., a plasmid) through the action of specific enzymes that serve to cut and ligate DNA fragments. DNA digestion and DNA ligation use specific restriction enzymes and DNA ligases, respectively, in order to insert the foreign DNA fragment. For this purpose, restriction enzymes that generate single-stranded overhangs are preferred to create sticky ends which bind by complementary base pairing. Subsequently, a DNA ligase enzyme joins the DNA fragments together in order to create recombinant DNA molecules. DNA Ligation is often achieved by using a specific T4 DNA ligase, while there are many restriction enzymes that generate sticky-ends (e.g., BamHI, EcoRI, BaI228I, etc).

Tendon sheaths ________. Tendon sheaths ________. are lined with dense irregular connective tissue help anchor the tendon to the
leonid [27]

Answer:

Tendon sheaths <u>act as friction-reducing structures.</u>

Explanation:

Tendon sheaths are fibrous tissue that is around tendons to protect and make the movements of these smoother. For example, they reduce the friction of the flexors and extensors tendons of the hand. These are tendons that we constantly use to open and close our hands when we want to grab objects. Without the sheath, the tendons will not move easily, and due to the excessive use, there can be inflammation.

The sheats have two layers, one internal, which is a synovial one that produces synovial fluid to lubricate the tendon, and the external, which is a fibrous layer.

2. Arrange these organisms into a food web:
Serjik [45]

Explanation:

A food web shows how organisms in a community prey and feed on each other (feeding relationships). It is composed of many interconnected food chains. In addition, it, therefore, shows how energy is transferred up an ecosystem from the primary producers (in this case the trees and grass) to the tertiary consumers (in this case the hawks and wolves).
