drag each label into the appropriate category to designate whether the given item describes elements of gray or white matter of the spinal cord.
In regards to the composition of the spinal cord, the grey matter is the centermost substance, whilst white matter is located towards the peripherals.
Though I could not locate the labels and categories online in order to properly classify each one, I can provide a general overview of the subject to aid in your understanding and ability to complete the project.
The spinal cord acts as a path through which billions of signals from the brain travel to reach the rest of the body. This pathway is occupied by grey and white matter, which are the representation of the billions of neurons that make up the central nervous system.
Grey matter is located towards the center of the spinal cord and is often described to be in the shape of a butterfly. Grey matter is the accumulation of nerve cell bodies and unmyelinated axons. In contrast, white matter makes up the surrounding area to that of grey matter and corresponds to the myelinated axons of various nerve cells. The white coloration of the white matter is due to the myelin itself.

usefulness of earthworm
Answer:By their activity in the soil, earthworms offer many benefits: increased nutrient availability, better drainage, and a more stable soil structure, all of which help improve farm productivity. Worms feed on plant debris (dead roots, leaves, grasses, manure) and soil. ... Nitrogen in the casts is readily available to plants.
Explanation:
Earthworms have the ability to eat and mix large amount of soil and organic matter and deposit it in the form of casts. They also enhance incorporation and decomposition of organic matter, increase soil aggregate stability, improve porosity and water infiltration, and increase microbial activity.
Describe how bacteria are used to produce enzymes for washing powders.
Answer:
By using genetic engineering to insert the gene for the desired enzyme into the bacterial chromosome, then growing large amounts of the modified bacteria in fermenters.
Explanation:
Answer:
Bacteria such as fungi or algae are inserted in fermenter and feedstock such as glucose, amino acid, sucrose are inserted to be a source of food for them.
Then they are left for a time for the bacteria to reproduce more and to produce more enzymes in their cells, Then if the enzymes are extracellular they are extracted directly from the filtrate, if they are intercellular they are separated from the feedstock and crushed to be separated with any solvent such as water.
By using genetic engineering to insert the gene for the desired enzyme into the bacterial chromosome, then growing large amounts of the modified bacteria in fermenters.

which molecules determine the tissue specificity of hormones?
Answer:
Steroids. Which molecules determine the tissue specificity of hormones? Receptors. Hormones bind to receptors on target cells and trigger a cellular response.
Explanation:
The tissue specificity of hormones is determined by hormone receptors. Proteins called hormone receptors are found on the cell surface. A hormone's binding to its receptor starts a chain of actions that eventually affects the activity of the cell.
For various hormones, different cells have various receptors. This implies that a hormone can only attach to cells that also contain such receptors. The tissue specificity of hormones is a result of this.
For instance, the insulin hormone attaches to receptors on cells in the muscle, fat, and liver tissues. These receptors bind to insulin, which sets off a series of processes that eventually result in the absorption of glucose from the circulation by these cells.

Which of these options is not a mechanism to control the opening and closing of ion
channels?
a) ATP binding (ATP gated)
b) Ligand binding (ligand gated)
c) Changes in membrane potential (voltage gated)
d) Distortion of the cell membrane (mechanically gated)
Answer:
D) ATP binding (ATP gated)Explanation:
There are three types of ion gated channel regulated by ligand binding, change in membrane potential and distortion of the cell membrane...
So the answer is ATP Binding( ATP gated) is not a mechanism to control opening and closing of Ion channels.
ATP binding (ATP gated) IS NOT a mechanism to control the opening and closing of ion channels (Option a).
ATP-gated channels are membrane channel proteins that open in response to binding ATP.
These channels require energy in the form of ATP to open and thus allow the passage of ions/molecules across biological membranes.
For example, the P2X7 receptor is an ATP-gated channel that mediates apoptosis (programmed cell death) of immune cells.
In conclusion, ATP binding (ATP gated) IS NOT a mechanism to control the opening and closing of ion channels (Option a).
