Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes. However, unlike prokaryotic cells, eukaryotic cells have: a membrane-bound nucleus. numerous membrane-bound organelles (including the endoplasmic reticulum, Golgi apparatus, chloroplasts, and mitochondria)
<span>After one round of replication, you get two brands namely parental DNA, Daughter DNA.The parental DNA is would remain intact.The daughter DNA would be entirely new.After one round of replication in the semi conservative model, all the double standard DNA is composed of one heavier parental and one daughter parental strand.</span>
Answer:
When organisms use organic matter for cellular respiration, ALL the matter goes back into carbon dioxide, water, and minerals, while ALL the energy leaves the ecosystem as heat (which is ultimately radiated out into space). So matter cycles, energy flows through ecosystems.
The name of the tear collecting structure under the skin near the bridge of the nose is the lacrimal sac. The lacrimal sac is part of the lacrimal drainage system or the lacrimal apparatus. The tears are produced in the lacrimal gland and will drain through a hole near the lower palpebral conjuntiva called the puncta which serves as the entrance in the lacrimal system. The tears will now enter the canalicula which serves as the passage way from the puncta to the lacrimal sac. Lastly, the tears in the lacrimal sac will drain to the nasolacrimal duct and to the nose. This also explains why we get runny nose when we are crying.
