Biology

Rashid [163]3 years ago
5 0

Answer:

The earth is a vast, complex system powered by two sources of energy: an internal source (the decay of radioactive elements in the geosphere, which generates geothermal heat) and an external source (the solar radiation received from the Sun); the vast majority of the energy in the earth system comes from the Sun.

Everything in Earth's system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called "spheres." Specifically, they are the "lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air).

Tanya [424]
False the process is reversed. Photosystem ll happens before photosystem l. I know that's weird but it's true. In photosystem ll which happens first it makes the energy carriers for ATP Synthase to happen in Photosystem l which is the next phase. Hope this helped!

In all cells, separation of replicated chromosomes is a prerequisite for cell division. However, the mechanism of chromosome sep
Ipatiy [6.2K]

1. two copies of the duplicated chromosome are attached at their centromeres before separating

2. chromosomes replicate before cell division

3. chromosome separation begins at the origin of replication on DNA

4. Before separation duplicated chromosomes condense; nuclear envelope fragments permitting chromosome separation

5. replicated chromosomes separate by attaching to some other structural feature of the cell

Explanation:

In the given question, the DNA replication steps of both prokaryotes and eukaryotes are provided in which some are common to both eukaryotes and prokaryotes and some are unique to the prokaryotes and eukaryotes.

<u>Eukaryotes </u>

1. Option-4 as the nuclear envelope is present in eukaryotes only.

2. Option-1 as centromere allows the kinetochores bind to the centromere which separates the chromosome.

<u>Bacteria </u>

1. Option-3 as DNA replication process separates the strand of the DNA.

<u>Both </u>

1. Option-5 as the chromosomes separate by other structures like microtubules

2. Option-2 as genetic material to be passed on to the generation must be replicated.
