The correct answer is (a.) a mutation of the hemoglobin allowing better oxygen-carrying capacity. The mutation of the hemoglobin that allows a better oxygen-carrying capacity would be the most beneficial to an elephant and its descendants.
Answer:
Cell Wall: This is the rigid outermost layer of a plant cell. It makes the cell stiff -providing the cell with mechanical support - and giving it protection. Animal cells do not have cell walls. Cell Membrane: This is a protective layer that surrounds every cell and separates it from its external environment.
Answer: Option A and D.
Soups chemical synaptic transmission.
Sparks direct electrical transmission.
Explanation:
Intercellular communication refers to the communication and interaction that exists between two cells in the body. It could be hormonal or synaptic transmission.
Synapse is the site where electric nerve impulses are transmitted between two nerve impulses.
There are two synapse possibilities which are electrical and chemical.
The Sparks and soups mean that the scientific discovery over the transmission of nerve impulses as to whether they are electrical impulses (Sparks) or chemical impulses(soup).
Chemical synaptic transmission means there is no physical touch in the space chemical are released and move to the neighbouring cells.
Electrical transmission means neuron physically touch and give way for flow of impulses between cells.
