A peplomer is a glycoprotein spike on a viral capsid or viral envelope. These protrusions will only bind to certain receptors on the host cell; they are essential for both host specificity and viral infectivity.
Answer:
A) Cardio respiratory fitness is the ability of the cardiovascular and respiratory systems to supply oxygen to muscles.
Explanation:
Cardio respiratory fitness is referred to as the ability of the cardiovascular and respiratory systems to supply oxygen to muscles. Constant exercise enables the circulatory and respiratory systems to be more efficient and effective by making the muscle of the heart large enough to allow more blood to be pumped with each beat and an expectant increase in the number of arteries in the skeletal muscles which supply blood to the active muscles. Exercise enhances the respiratory system as well as the heart when it increases the amount of oxygen that the body inhales and shared to the body tissues.
Answer/Explanation:
Density-dependent limiting factors are non living and biotic factors that affect the size and growth of a population based on the population density, while density-independent limiting factors are those factors that do not depend on the density of a population before they can have an effect on the growth and size of the population.
Examples of density-dependent limiting factors are predation, disease, Parasitism, competition. These rely on the density of a population in order to affect the growth and size of a population.
On the other hand, examples of density-independent limiting factors are pollution, flood, temperature.
