A teacher writing to a confused student.
bacteria are microscopic (very tiny) organisms that are unicellular (made up of a single cell). One fundamental difference is that bacterial cells lack intracellular organelles, such as mitochondria, chloroplasts, and a nucleus, which are present in both animal cells and plant cells.
Answer:
it should be,
AaBb × AaBb
Explanation:
where,
RY(round, yellow) and ry( wrinkled,green) which gives RrYy( round, yellow)...which is also called 1st filial generation ( F1)...when Mendel self hybridised the F1 plants he differentiate the plant in 9: 3: 3: 1...which is F2 generation.
Diluting an acid decreases the concentration of H+(aq) ions , which increases the pH level of the solution towards 7 , making it less acidic . However , the pH level of an acidic solution cannot become greater than 7 , because the water you add to dilute it is not alkaline .
Answer:
this shows that at one point these animals lived on the surface because there were plants for them to eat

Answer:
Nerve cells release chemical signals into synapses between them (short distance). They also transverse their lengths with an electrical signal that can result in signal travel along a series of cells (long distance).
Explanation:
Nerve cells release neurotransmitters in the synaptic cleft which are capable of affecting nearby cells such as other nerve cells and muscle cells. Neurotransmitter molecules include, among others, serotonin, acetylcholine, dopamine, norepinephrine and histamine. Moreover, the synaptic cleft is the space that separates a neuron cell and its target cell. On the other hand, neurons transmit signals through electrical impulses. Electrical impulses travel long distances in the body carried by axons of the nerves. Thus, nerve impulses connect the brain and spinal cord and they carry signals to different parts of the body.
