<span>How are the dark reactions that occur in plants dependent on the light reactions?
a.The chemical energy used in the dark reactions is produced in the light reactions.

Photosynthesis is divided into two parts.
1) Light - dependent reaction
2) Light - independent reaction

Light dependent reaction absorb energy from the sun to produce ATP and NADPH, these energies are used in the light-independent reaction. The ATP provides the energy, while the NADPH provides the electrons required to fix the carbon dioxide into carbohydrates.

Identify the cellular structures and it’s functions
Eva8 [605]

The cellular structures include cell nucleus, nuclear pores, genetic material (DNA), cytoplasm, nuclear lamina, cell membrane, mitochondria, cytoskeleton and lysosome. It is an animal cell.

<h3>Cellular structures and organelles </h3>

The cellular structures observed in the Figure include cell nucleus (A), nuclear pores (B), genetic material (C), cytoplasm (D), nuclear lamina (E), cell membrane (F), mitochondria (G), cytoskeleton (E) and lysosome (F).

The cell nucleus is an organelle that contains the genetic material (DNA) in eukaryotic cells.

The nuclear pores are little pores in the nuclear membrane that allow the passage of small molecules (e.g., RNAs, transcription factors) by simple diffusion.

The genetic material (DNA) contains the instruction to synthesize all cellular components.

The cytoplasm is an aqueous solution inside the cell, which is mainly composed of dissolved proteins and salts.

The nuclear lamina is a rigid structure located inside the cell nucleus which serves to provide structural support to this organelle.

The cell membrane is a semipermeable lipid bilayer that allows the passage of certain substances in and out of the cell.

The mitochondria are the energetic factories of eukaryotic cells, which act to generate ATP by a process called cellular respiration.

The cytoskeleton is an interconnected network of protein filaments that provides structural support to the cell.

The lysosome is an organelle inside animal cells that contains hydrolytic enzymes used to degrade different substances.

You are studying an alien bacteria-like organism isolated from the clouds of Venus. You decide to repeat the Meselson-Stahl expe
fenix001 [56]

Answer:

it is expected to observe two bands: one band of light density and one band of heavy density

Explanation:

DNA replication is semiconservative because when DNA is replicated both resulting DNA molecules are composed of one original strand and one newly synthesized strand. If DNA replication would be conservative, then the original DNA molecule would serve as a template to produce a new DNA molecule, thereby each cell division would produce one daughter cell with a new DNA molecule and one daughter cell with the original DNA molecule of the parental cell. In this case, the transfer of bacteria-like organisms into a heavy 15N medium would produce two types of DNA cells after replication: cells with original DNA of light density (14N) and cells with new DNA of heavy density (15N), which would be distributed in two bands after centrifugation.
