Answer:
Physical traits are observable characteristics determined by specific segments of DNA called genes.In technical terms, a genetic trait is amenable to segregation analysis rather than quantitative analysis.
Explanation:
Trait is a specific characteristic of an individual. For example, their hair color or their blood type. Traits are determined by genes, and also they are determined by the interaction with the environment with genes. And remember that genes are the messages in our DNA that define individual characteristics.
Can't see the chart. But chloroplasts, cell wall, central vacuole are only in plant cells
Answer:
I agree with Joelle.
Explanation:
Just out of common sense, not all cells are the same.
-Sienctists have studied and evaluated that cells in different matter have different make-ups. For instance, plant have cell walls and a cell membrane while animals (incluing humans) only have a cell membrane. Plants have a chloroplast, used to make their own food using the process photosythesis, While animals don't, an consume other living things.
-I don't know if you have to fill it out or anything, but if you were to fill it out, You'd put a check under each cell part for each thing.

Answer:
As this is DNA replication, this is the unwounding process
Explanation:
In DNA replication, the parent DNA to be replicated is unwound to enable access of the replication machinery (replisome) to this genetic material. The origin of replication will be identified first, which in the prokaryotes is only one, and in the eukaryotes, we have many. This sites are recognized by specific sequences on the genome. after this, melting of the DNA occurs at this origin creating a replication bubble and two replication forks. This allows for the unwinding of the DNA by the enzyme Helicases in the direction of the replication fork. Another enzyme present in this step is also the single strand binding proteins (SSB). These proteins function in the prevention of re-anealing of the unwound DNA strand by attaching themselves to each strands. Another enzyme called the topoisomerases also function here by reducing the torque (twisting) produced upstream of the replication fork as result of DNA unwounding. An example is the gyrase
