Answer:

Explanation:Many viruses follow several stages to infect host cells. These stages include attachment, penetration, uncoating, biosynthesis, maturation, and release. Bacteriophages have a lytic or lysogenic cycle.

The life cycle of viruses may be divided into the following stages:

1. Attachment

Attachment is a specific binding between viral surface proteins and their receptors on the host cellular surface. This specificity determines the host range of a virus. For instance, the human immunodeficiency virus (HIV) attacks only human's immune cells (mainly T cells), because its surface protein, gp120, can interact with CD4 and chemokine receptors on the T cell's surface (Figure 1-E-3).

2. Penetration

Following attachment, viruses may enter the host cell through receptor mediated endocytosis or other mechanisms.

3. Uncoating

Uncoating is a process that the viral capsid is degraded by viral enzymes or host enzymes.

4. Replication

Replication involves assembly of viral proteins and genetic materials produced in the host cell.

5. Release

Viruses may escape from the host cell by causing cell rupture (lysis). Enveloped viruses (e.g., HIV) typically "bud" from the host cell. During the budding process, a virus acquires the phospholipid envelope containing the embedded viral glycoproteins.

1. Describe the movements of transverse adduction and flexion for the pectoralis major and biceps brachii muscles.
Cerrena [4.2K]

Answer and Explanation:

The pectorals major is an enormous, fan-formed muscle covering the chest. It is included clavicular and sternocostal areas. Adducts and turns the upper arm. Transverse adduction and flexion of the pectoralis major is smooth movement. You can see the muscles extending far and contracting back effectively.  

The biceps brachii is a two-headed muscle. Despite the fact that most of the bulk is found anteriorly to the humerus, it has no connection deep down itself. The activity is Supination of the lower arm. It likewise flexes the arm at the elbow and at the shoulder. In the biceps brachil there isn't a lot of expansion found in the muscle contrasted with the pectoralis major.
