<u>Unusually cold winter</u> is a density-independent factor for a flock of Canada geese on a large lake.
Density independent factors mean that those factors/variables affect the density of the population. However, the density of the population, on the other hand, does NOT affect the variable.
Explanation:
The other factors are density-dependent except unusually cold winter. The cold is not affected by the population density of the Canadian geese. However, an increase in cold causes the population density to decrease because some individuals in the population will be unable to cope with the cold. Only individuals with traits favorable in the bitter cold survive.

The option D is correct :The gametophytes of seed plants are never exposed to the external environment. Unlike spores, The gametophyte in seed plants is often tiny and is kept in the tissues of the sporophyte. The integument refers to the layers of sporophyte tissue that encircle the megasporangium.
seeds carry food reserves that can be used to support a young plant. While spores are distributed by the wind, seeds can be spread by animals. While spores only live a few days, seeds can slumber for weeks or even years. Seeds contain a supply of food in storage, in contrast to spores. If the conditions are right, seeds that have been transported far from the parent sporophyte may germinate and rely on stored nourishment to develop into seedlings. Spores and seeds vary primarily in that seeds have stored nourishment in their endosperm, which allows them to germinate in adverse conditions whereas spores do not, making them more dependent on good conditions for germination.

In common terms, the ventilation cycle is known as “Breathing” and its cycle is in and out movement of air from the lungs. Inspiration is defined as airflow inside the lung and expiration is when the air leaves the lungs with a small pause between inspiration and expiration known as the rest period.
For the body to get oxygen and expel carbon dioxide, inspiration (breathing in) and expiration (breathing out) are essential actions. Expiration is often passive unless it is pushed, whereas inspiration involves the active contraction of muscles, such as the diaphragm.
