During meiosis when the spindle fibers pull apart the chromosomes this happens at radon so there are different variations of genes being pulled apart
Embryonic stem cells,
Tissue-specific stem cells.
<span>The probability of an action potential being propagated from neuron to neuron is increased when the postsynaptic neuron's signal is in an excitatory state. During this state, the action potential of a presynaptic neuron increases the probability of transmission of a signal to the postsynaptic neuron.</span>
Answer:
Since they need to float, leaves on the surface of plants are flat. 6. The presence of air sacs enables them to float. Their roots are smaller so water can spread freely and directly into the leaves
Large central vacuoles, chloroplasts, and cell walls are only found in plant cells.
Large central vacuoles store nutrients and waste products, but they also maintain the plants' structures.
Cell walls also maintain structure and rigidity.
Chloroplasts are used in the process of photosynthesis, which only occurs in plants.
