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
The cellular membrane, in the case of cells that don't have a rigid cellular wall, outlines the cell and contains the cytoplasm but it's the cytoskeleton that is more responsible for the shape of a cell, which come in a variety of shapes: squamous, cuboide, colunar, neurons, etc. In cells that do have a rigid cellular wall, such as plant cells, it's the cellular wall that gives it <span>its shape.</span>

Answer:
Corpus callosum
Explanation:
Corpus callosum is the red part of the brain that has a “C” shape. The corpus callosum, which is made up of over 200 million of neural fibers, links both hemispheres of the brain (the left and right brain) together, which allows for coordination and complex communication between both in order for the brain to function properly.
This structure usually starts forming about 12 weeks after conception of a child, and continues to develop up to about 12 years of age of the child.
The main function of the corpus callosum is the ensuring of uninterrupted flow of information, and the integration of complex information and tasks such as motor, sensory and cognitive functions between both hemispheres of the brain.
