Answer:

Gated ion-channels

Explanation:

These ion channels are protein molecules that act as a passageway which span across the cell membrane allowing the movement of ions from one side of the membrane to the other. They possess the ability to open and close in response to either chemical or mechanical signals.They possess a fluidic pore, which becomes available to ions after a conformational change in the protein structure has been activated causing the ion channel to open.  Based on the stimulus to which they respond, ion channels are divided into three groups: voltage-gated, ligand-gated and mechano-sensitive ion channels. Channels responding to electrical (voltage-dependent ion channels), mechanical, or chemical (ligand-gated ion channels) stimuli open and allow rapid ion movement into or out of the cell, and this movement creates an electrical signals.

A stock transfer can involve movements:______ A. Between different plants within the same storage location. B. Between stroage l
gogolik [260]

Answer:A,B,D,E,F

Explanation:

Stock can be transfer depending on the organization.

The movement of stock is divide into three broad categories

Stock transfer from Plant to plant- movement of stock from a plant to another plant

Stock transfer from Company code to company code- movement from ome company code to another

Stock transfer from Storage location to storage location

Between different plants within the same storage - stock can be moved from one plant to another within the same storage this will lead to a change in quantity in both plant and it should be noted

Between storage locations within one plant- stock location can be change in a plant but it doesn't affect the quantity.

Between plants in different company code- stock can also be moved from one company code to another this requires adequate documentation when the stocked are moved.

The diagram shows two cells. Identify structures C, D, and E and explain how they work together to perform a specific process wi
soldi70 [24.7K]

Structure C, D, and E in the diagram represent the endoplasmic reticulum, the ribosome, and the Golgi apparatus respectively.

When the ribosomes are attached to the endoplasmic reticulum, they give it a rough appearance.

The ribosome, endoplasmic reticulum, and the Golgi apparatus work together in the synthesis and transport of protein within the cell. In other words, they are all involved in the secretory pathway of cells.

  • The ribosome represents the actual site of protein synthesis.
  • The endoplasmic reticulum gets involved by folding the synthesized proteins and packaging them into secretory vesicles. Thereafter, the vesicles are transported to the Golgi apparatus.
  • The packaged proteins undergo further processing within the Golgi apparatus before they are exported to the cell membrane via the cytosol.

In other words, the 3 organelles work together to form the secretory pathway of the cell. They are involved in the synthesis, packaging, processing, and eventual transport of proteins to their target sites.

Juliette [100K]

If the food is limited to the squirrels then that could impact how well they reproduce which could impact their numbers which therefore could impact the food source for the foxes which eat them. Fewer squirrels means the foxes will slow down on their reproductive numbers as well...they are all linked!

From deep to superficial, the order of the strata of the epidermis is corneum - granulosum - lucidum - spinosum - basale. spinos
kotykmax [81]

Answer:

basale - spinosum - granulosum - lucidum - corneum.  

Explanation:

The order of strata in the epidermis:

  • Basale: it is the deepest stratum. It has one layer of cells called keratinocytes, which are stem cells for the epidermis.
  • Spinosum: The keratinocytes in this layer have spiny shapes. They synthesize cytokeratin and lipids. In this layer, we can also find macrophages.
  • Granulosum: The keratinocytes of the previous layer ascend and synthesize keratohyalin, which is in granules. The keratohyalin helps to join keratin filaments. Also, the cells release the lipids synthesized in the previous layer, and they form a barrier that stops dehydration.
  • Lucidum: it is only on thick skin, like the one in the sole of the feet. The keratinocytes in this layer have expelled the nucleus and now are dead cells. The keratinocytes have a flat shape and form a thin layer.
  • Corneum: it is the most superficial layer. It is made of dead keratinocytes filled with keratin in their cytoplasm. It is a thick layer that suffers desquamation when new dead cells filled with keratin ascend from the previous layer.
