Answer:
Bubbles are a sign that the yeast is alive, and that it is performing anaerobic respiration. You should notice that the mixtures with too little and too much sugar do not grow, bubble or foam properly. This is because the yeast needs the perfect amount in order to produce carbon dioxide.
Explanation:
In meiosis the are two divisions. The division of the original cell results in two daughter cell. Those two cells divide to produce 4 haploid cell in total.

Answer:
Cellular communication
Explanation:
At the end of a neuron, there is a space called the synaptic junction that helps it communicate with another neuron or organ in order to produce a response. When the impulse reaches the end of a neuron usually called the axon terminal, it causes the opening of voltage gated ion channels that causes the influx of ions inside the cells. This in turn will cause synaptic vessicles that contain neurotransmitters to move towards the membrane of the axon terminal and fuse with the membrane then open up to release the neurotransmitters into the synapse (space between the 2 neurons). When this happens, the voltage gated channels close. The neurotransmitters then bind to ligand receptors on the second recieving neuron that cause it to produce an effect like stimulate an organ or produce an impulse . After using up the neurotransmitters, they can be recycled or broken down into metabolytes that are used up by the cell.
Answer:
Codominance
Explanation:
Codominance is a pattern of inheritance when none of the alleles of a gene is dominant over the other allele of the same gene. When present together in a heterozygous genotype, both the alleles are able to express themselves. In the given example, a cross between blue and yellow flowered plants obtained the progeny with blue and yellow speckled flowers. Here, the alleles of blue and yellow flower color are codominant and express themselves in the hybrid progeny.
