Answer:
Four daughter cells are produced each with 40 chromosomes. The daughter cells would exhibit genetic variations and would not be genetically identical to each other.
Explanation:
Meiosis is a cell division that forms four daughter cells from one parent cell as two sequential division meiosis I and meiosis II do not include any DNA replication between them. Crossing over during prophase-I of meiosis-I includes the exchange of genetic segments and occurs between the homologous chromosomes. It produces new gene combinations in the daughter cells which were otherwise not present in the parent cell.
Since there is no DNA replication between meiosis I and meiosis II, the daughter cells have half the number of the chromosomes compared to the parent cell. This occurs as homologous chromosomes move towards the opposite pole during anaphase I.
Therefore, a parent cell with 80 chromosomes will make a total of 4 daughter cells by meiosis. Each daughter cell would have 40 chromosomes. These daughter cells would have some new gene combinations and would be genetically dissimilar among themselves.
Answer:
c. hominoid
Explanation:
Based on the information provided within the question it can be said that in this scenario the best classification for this fossil would be ac. hominoid. This term refer to all the apes species including gibbons, gorillas, chimps, orangutans, and humans. Therefore since the fossil indicates upright posture, slow climbing and hanging below branches we can say that they were hominoid.

<u>Answer:</u>
The process of "Osmosis" is modeled in the plant cell diagrams seen here.
<u>Explanation:</u>
Osmosis is the natural gross migration of solvent particles into a zone of higher solute concentration via a selectively permeable membrane, in the path that seeks to balance the amounts of solvents on both the ends. Osmosis as biological membranes are semipermeable, is a critical mechanism in biological systems.
Such membranes are usually impenetrable to massive and polar molecules like polysaccharides, ions and proteins while being porous to hydrophobic or non-polar molecules like lipids and to small molecules as carbon dioxide, oxygen, nitric oxides and nitrogen.
