Feedback loop. Hope this helps! :)

Answer:

Feedback loop

Explanation:

The ADH (Vasopressin - Antidiuretic Hormone) feedback loop is an example of negative feedback in the kidneys. Negative feedback occurs when the body works to counteract changes made to the body system. ADH is released when there isn't enough water (dehydration) so that the body can retain as much liquid as possible.

Hello! I have a question and I ask if you can make it a bit detailed. I am struggling to understand the Calvin Cycle in the proc
igomit [66]

Absolutely!  The Calvin Cycle is a process that takes place within the stroma of chloroplasts during photosynthesis.  This cycle is a light-independent reaction because it does not need sunlight to fully develop.  The process is, however, dependent on ATP and NADHP from those light reactions.

If you want a really good study guide for the Calvin Cycle, just follow this link; it helps A LOT!

A biochemist isolates and purifies various molecules needed for DNA replication. When she adds these molecules to DNA, replicati
olga55 [171]

Answer:

DNA ligase

Explanation:

<em>The biochemist must have left out DNA ligase enzyme.</em>

<u>The DNA ligase enzyme is able to catalyze the formation of phosphodiester bonds and as such, capable of joining strands of DNA together to form a single strand.</u>

The numerous DNA segments of a few nucleotides long observed by the biochemist must have been the replicated product of the lagging DNA strand. The lagging strand is replicated discontinuously in short strands because the DNA polymerase enzyme can only elongate primers in 5' to 3' direction. The short segments are known as Okazaki segments and are usually joined together to form a whole strand by the DNA ligase enzyme.

Hence, the missing component is the DNA ligase.

Cytoskeletal elements play important roles in cell division. The mitotic spindle apparatus is made of ________ and pulls sister
Veseljchak [2.6K]

Answer:

Cytoskeletal elements play important roles in cell division. The mitotic spindle apparatus is made of "microtubules" and pulls sister chromatids apart, whereas the contractile ring is made of "actin filaments" and required for the separation of daughter cells at the end of the mitotic phase of the cell cycle.

Explanation:

The three chief organizational apparatuses of the cytoskeleton are microtubules (formed by tubulins), microfilaments (formed by actins) and intermediate filaments. All three apparatuses cooperate with each other non-covalently. The cytoskeleton is composed of protein filaments and is found throughout the inside of a eukaryotic cell. The cytosol is the main component of the cytoplasm, the fluid that fills the inside of the cell. The cytoplasm is everything in the cell except for the cytoskeleton and membrane-bound organelles.
