Answer:
It is possible for large molecules to join a cell by a method called endocytosis, where a small piece of the cell membrane surrounds the particle and is brought into the cell. If the particle is solid, endocytosis is also dubbed phagocytosis. If fluid droplets are taken in, the process is called pinocytosis.
Answer: ENERGY AND MATTER MOVE between the land, water, atmosphere, and biosphere — between the four spheres. In addition to natural interactions, human activities, such as the clearing of rain forests, can affect interactions between the spheres.
Explanation:
Organic molecules can range in size from simple molecules to complex structures containing thousands of atoms! Although carbon is present in all organic compounds, other elements such as hydrogen , oxygen , nitrogen , sulfur and phosphorus are also common in these molecules.
Answer:
The correct answer is: semi-conservative.
Explanation:
DNA replication is an important process in which the DNA is duplicated before cell division so each daughter cell can have a copy of genetic material.
DNA replication is <u>semi-conservative because one strand of DNA is new and the other one is the old strand</u>. To replicate itself, the DNA double helix is opened, and then each strand serves as a model for the new strands.
DNA replication is <u>not a one-step process</u>, as it takes several complicated steps in which <u>lots on enzymes participate</u> (like DNA polymerase and DNA helicase).
DNA replication is <u>also carried by prokaryotic cells</u>, though it's a much simpler process.
