Yes, species pairs show more than one barrier to reproduction. Examples include damselflies with incompatible reproductive organs, species of flowers attracting different pollinators, bird species with different mating dances, and species producing infertile offspring.
Yes, there are several instances where species pairs show more than one barrier to reproduction. These barriers can be prezygotic or postzygotic. Examples include damselfly males and females of different species that have differently shaped reproductive organs, thus creating a mechanical barrier. This means their body parts simply do not fit together and reproduction cannot occur.
Also, two species of flowers may attract different pollinators, creating a barrier known as habitat isolation, in which the species live in the same area but different habitats. Furthermore, bird species may display different mating dances. This is behavioral isolation where species differ in their mating rituals. There's also reduced hybrid fertility where two species of insects produce infertile offspring. The mechanisms of reproductive barriers in nature are complex and diverse in their operation.

Answer: The correct answer for the fill in the blank is Light dependent phase of photosynthesis.
Photosynthesis ( synthesis of food in presence of sunlight) is primarily divided into Light dependent and light independent phase.
Light dependent phase occurs in the thylakoid membrane within chloroplast and the chemical reactions taking place in this phase are also called Hill reaction. Energy from sunlight is absorbed and converted into chemical energy in the form of ATP and NADPH and Oxygen is produced due to splitting of water in this phase.
Ecology is the study of interactions among organisms and their environment.
The definition of ecology aligns with option c: the study of interactions among organisms and between organisms and their environment. This scientific field aims to understand the distribution and abundance of living organisms, the interactions between these organisms and their surroundings, and how such interactions are affected by natural and human-made changes to the environment.
Besides, the other options given represent the concepts related to but not accurately defining ecology. For example, option a refers to environmentalism, while option b refers to recycling, and option d typifies sustainable living.

Answer:
A floodplain is the answer
likely reason for this?
A. Viruses attract antibodies in the atmosphere.
B. Viruses require a low atmospheric pressure.
C. Viruses are hosts for bacteria that eventually
destroy them.
D. Viruses are dependent on host cells of living
organisms.
Answer:
D
Explanation:
Without a host a virus is without key nutrients to survive
