Answer:
1. Muscle: soft, contractile tissue important to produce force and motion in animals.
2. Fascicle: multiple bundles of skeletal muscle fibres which is surrounded by a type of connective tissue called perimysium.
3. Muscle fibres: bundles of cylindrical organelles myofibrils formed by the fusion of myoblasts via myogenesis process.
4. Myo-fibril: basic unit of a muscle cell made of thick and thin myofilament arranged in parallel columns along the length of muscle fibres.
5. Myo-filament: strands of actin and myosin proteins which pack a muscle fiber and are force generating structures.
Explanation:
From my speculation it is loss of habitat and global warming
<span>Structures that have a similar evolutionary origin and structure but are adapted for different purposes, such as a bat wing and a human arm, are called </span>homologous.
Answer:
Option C, an enormous surface area for gas exchange
Explanation:
The process of gas exchange in any mammal depends on following factors -
a) Thin membrane of respiratory surfaces involved in gas exchange
b) High speed of diffusing gases
c) High Surface area
d) Solubility (lipid solubility) of carbon dioxide and oxygen
The rate of diffusion of gas across a membrane is directly proportional to the surface area of the membrane through which diffusion is taking place. Thus, the higher the surface area, the higher is the gas exchange.
Hence, option C is correct
