<u>ANSWER:</u>
The correct order is- Zygote, Blastula, Gastrula, Fetus.
<u>EXPLANATION:</u>
- The embryo develops from the zygote which is formed when the gametes fuse in the process of "fertilization".
- The zygote undergoes cell division to form blastula which is a "ball of cells".
- Gastrula leads to the rearrangement of cells of the blastula into three layers that differentiate into different systems of organ.
- The last stage is the fetus which then develops into a baby.
Answer:
b
Explanation:
its b because it doesnt say any else then 15 or any clues so its tryna trick u
<span>Membrane permeable to a liquid (solvent) and impermeable (or poorly permeable) to substances dissolved in the liquid (solute). It can be natural or synthetic.
Depending on the membrane and solute, the permeability may depend on the size, solubility, properties, or chemical composition of the solute itself.
If molecules are small enough, then it can pass through the semi-permeable membrane, because the permeability is </span>inversely proportional to the molecule size.
<span>For example in hemodialysis, electrolytic equilibrium and toxics' elimination are performed by subjecting the patient's blood to the dialysis physical principle. It is made to slide in a filter in which it comes in contact with a semi-permeable membrane through which pass only or at least in a greater quantity of toxic substances) that you want to remove.</span>
Answer:
e. whether or not the impulse begins in the CNS
Explanation:
Nerve impulse is action potential movement through the axon. Nerve impulse propagation has its velocity (speed at which nerve impulse travels down the axon) which depends on many factors. For example, myelination increases the conduction velocity. Also, the larger the diameter of an axon, the higher the velocity is. Nodes of Ranvier present on the axons, and myelin sheath between the nodes act as a good electrical insulator which also increases the velocity.
