Answer:
un sapo puede cambiar su sexo a hembra para que puedan reproducirse incluso si no hay ninguna hembra.
Explanation:
Answer:The answer is diffusion.
Explanation: Unicellular organisms excrete waste by diffusion.
Unicellular organisms are organisms that have only one cell. They are called single cell organisms because all their life processes such as reproduction, feeding, digestion, and excretion, occur in only one cell. An example of unicellular organism is paramecium.
Diffusion is the inactive movement of molecules from the region of higher concentration to the region of lower concentration.
Since pressure is force per unit area, blood pressure could be thought as the force exerted by the blood to the surface area of your blood vessels. When your blood vessels dilate, it means that they expanded. The result would be faster flow of blood. When this happens, the force of the blood is not any more concentrated on your blood vessels because there is more room available.
Think of a faucet where tap water flows. When you stopper the faucet with your finger, you feel the force of the water. The pressure builds up as manifested by the sound your faucet makes. But when you release your finger, the water rushes through and flows faster. The pressure is released. Therefore, when your blood vessels are dilated, your blood pressure decreases.
Answer:
Dendrites
Explanation:
Dendrites or dendrons are the branching of protoplasmic extensions of a nerve cell. As the neurons are arranged in head to tail manner, these dendrites lie close to the axon terminals of the other neuron and thus they receive signals from the other neurons and then pass the received signal to the main body of the neuron which is also called Soma. The electrical signals are passed from one neuron to the other neurons via the synapses which are located at various points on the dendrites.
