Answer:
The density of a population can be regulated by various factors, including biotic and abiotic factors and population size. Density-dependent regulation can be affected by factors that affect birth and death rates such as competition and predation.
Answer:
The correct answer will be- false
Explanation:
The understanding of the biomechanics of the human movements is studied by the lever system which represents the rigid bar which comes on a fixed point as a result of the force exerted.
The lever systems are defined into three types into which the last lever system is the third lever system which is the recognized by the muscle (effort) in the middle of the joint (fulcrum) and the weight of the body (load).
These movements are related to the exercise like jumping, running and kicking which requires speed and distance to be covered. Thus, false is the correct answer.
the effort is the middle component and lies between the fulcrum and load.

Answer:
b. synthesis of cellular membrane components
Explanation:
Endoplasmic reticulum is a network of membranes fistulas; within the cytoplasm of a eukaryotic cells, where proteins and lipids are synthesized usually connected in continuum with the nuclear membrane of the cell.
The ER is of two kinds the smooth and the rough ER (Endoplasmic reticulum).
Functions of Rough endoplasmic reticulum includes; * Synthesis of protein * Degradation of worn out organelles
While the functions of Smooth endoplasmic reticulum includes; * Synthesis of lipid and steroids * Role cellular metabolism * Storage and metabolism of calcium * Catabolism of toxic substance.
Inference from the functions stated above shows that ER is actively involved in the synthesis of cellular membrane components.
