Answer:
Option A, keystone species
Explanation:
Keystone species are responsible for controlling any species from becoming dominant over all other species. The keystone species are found at the top of all the energy pyramids and food chains.
They control the explosion of population of prey and hence regulate the overall ecological diversity.
Some common example of keystone species is as follows –
Bison, prairie dog, large mammalian predators,
Hence, option A is correct
Answer:
The answer is C) Brain. The brain processes the signals that are sent to it from the nerves in your body.
Zea diploperennis<span> is a wild relative of maize that is endemic to the Sierra de Manantlán Biosphere Reserve in Mexico. Because this species is a priority for conservation in the reserve, the effects on its populations of the most common types of anthropogenic disturbance – slash-and-burn, and slash without subsequent burning – were investigated in three populations for 5 years</span>
Data have shown significant differences in nitrogen retention, blood cortisol concentrations, vital signs, water con- sumption, and urine production. Implications are that total energy balance is altered when an animal is exposed to ectoparasite infestations, thereby resulting in decreased productivity.
Answer:
I think it is C
Explanation:
Amino acids have various prominent functions in plants. Besides their usage during protein biosynthesis, they also represent building blocks for several other biosynthesis pathways and play pivotal roles during signaling processes as well as in plant stress response
