4. the first box is mutualism. second box is commensalism. third box is parasitism.
Answer:
Neurons have stable, relatively unchanging internal environments.
Explanation:
Neurons or nerve cells is the structural and functional unit of the nervous system. Neurons consists of the dendrites, axon, cell body and different cell organelles.
The neurons have mitochondria that meets the high ATP requirement and and consume more oxygen. The network of rough endoplasmic reticulum and ribosomes produce large number of proteins in neuron. The internal environment is never stable and gets changed as the nerve impulse transmission occur through the neuron. The membrane potential of the neuron gets changed and changes its internal environment.
Thus, the correct answer is option (B).
Answer:
Genetic pressure forces an animal to adapt to their environment, therefore changing their genetic code and contributing to genetic variation.
Firstly sunlight is needed for the chloroplast to get it activated by the photons in solar energy so that light dependent reactions take place. And then the raw materials like minerals,water,sunlight,etc... Are needed for the process photosynthesis.
