Endosperm and female gametophyte is the plant tissue that have high nutritional value. The function of endosperm is to protect the embryo and gives all the essential nutrient to the embryo.
Answer:
TRUE
Explanation:
Phasic receptors are sensory receptors that are fast acting in detecting changes in the strength of a particular stimulus or signal to the brain. They are fast adapting receptor cells that detect changes in the strength of a stimulus. Because of this fast adapting ability, they cannot be used by the CNS in constant signalling of stimulus. A different receptor called Tonic receptors are used by the brain for constant signalling because they are slow reacting cells are they continue to transmit signals to the CNS along as the stimulus remains and not to changes in the pressure or strength of the stimulus. Phasic receptors are so important in predicting the changes in the body fora given time and this helps to quantify how body can react to increase or release of a stimulus. because when stimulus is added it signals the brain for some time and it signals stops but when the stimulus is released, it also signals the brain detecting bodily deformations to various stimulus.
Darwin believed in evolution through natural selection; organisms that were the most well adapted to their environment would pass on their genes to their offspring (which the organism would have inherited at conception).
Lamarck on the other hand believed that organisms passed on traits that they had acquired during their lifespan to their offspring.
We know now that Darwin was correct, and that Lamarck was wrong.
