A single celled organism without distinct nuclei or organized
cell structure is called as a prokaryote.
Answer:
the cells fuse with existing muscle fibres, to regenerate and repair the damaged fibres
Explanation:
The muscle damage initiates a repair process in which certain hormones, along with the macronutrient protein, synthesize new satellite cells, which are used to repair the damaged muscle fibers. In other words, the role of protein is to help repair tissues damaged by exercise. When the muscle is damaged, these cells are stimulated to divide. After dividing, the cells fuse with existing muscle fibres, to regenerate and repair the damaged fibres. The skeletal muscle fibres themselves, cannot divide. However, muscle fibres can lay down new protein and enlarge (hypertrophy).
Answer:
Afecta a la estructura primaria de las proteínas.
Explanation:
Las proteínas tienen 4 niveles de estructura:
- Estructura primaria: es la secuencia de aminoácidos que forman la cadena peptídica de la proteína.
- Estructura secundaria: es el plegamiento de la cadena por unión con aminoácidos de la misma cadena dándole a la proteína la forma de alfa hélice o de lámina plegada.
- Estructura terciaria: la estructura secundaria de la proteína se pliega dando a la proteína una estructura globular, la cual hace a la proteína soluble, o fibrilar, la cual hace a la proteína insoluble.
- Estructura cuaternaria: dos o más proteínas con estructura terciaria se unen.
Si la xerodermia afecta la secuencia de aminoácidos, afecta la estructura primaria de la proteína ya que esta es el orden en que los aminoácidos se juntan para formar la cadena peptídica.
Copper. Copper(Cu) is deadly to sheep because excess amounts of copper are concentrated in the liver rather than being excreted. Over time, this excess of Cu can destroy liver tissue, resulting in death of the animal.

Predators, viruses, and others of the same species
