BaLLatris [955]

Explanation:

-these are likely different tissue systems or organs

-they each may execute different specified functions

Cells sharing a similar origin, group together in the body to form tissues; these typically share physical features and are arranged in regular patterns. All living things, grow, respire, reproduce etc. these processes are carried out by cells, which are thus integral to their survival.

Further Explanation:

These tissues form systems that may be

  • meristematic- temporary, found at growth regions called meristems; they are undifferentiated or incompletely differentiated and continuously undergo growth and division
  • non meristematic- permanent tissue, already differentiated and are made up of plant tissue that no longer divides

Meristems differentiate into three main plant tissue types, which make up several  tissues in various amounts:

  • ground
  • dermal
  • vascular tissues

Secondary tissue types are either complex, made up of several different call types, or simple, made up of the same cell type.  Dermal tissue covers the plant's outermost layer, and mediates gaseous exchange. While two types of complex vascular tissue, are the xylem and phloem.

Xylem vessel elements: mature xylem vessel is made up of dead cells called vessel elements aligned end-to-end where these ends have been dissolved and the protoplasm is absent. These form long, continuous tubes that facilitate the unobstructed flow of water and minerals to other areas within the plant.

Indicate whether each of the following phosphorylation events typically activates (A) or inactivates (I) the protein that is bei
Airida [17]

Answer:

<h2>Phosphorylation and dephosphorylation plays an important role in activating or inhibiting different proteins.</h2>

Explanation:

1. When Cdc25 is phosphorylated by M-Cdk, it activates the CdC25. It acts as checkpoint from G1 to S and G2 to M.

So, the correct answer is activates (A).

2. Phosphorylation of condensins by M-Cdk, degrades the condensin and begins the decondensation of chromosomes. That means it inactivates the condensin.

So, the correct answer is Inactivates (I).

3. Phosphorylation of APC/C activates it and then CdC20 can bind to it and then cell will progress through anaphase.

So, the correct answer is Activation (A).

4. Phosphorylation of Ndc80 by Aurora-B leads to binding of NdC80 to kinetochore and recruits the Ska complex at kinetochore.

So the correct answer is activates (A).

So, four-letter string is AIAA.
