Many chemotherapy drugs used to treat cancer work by modifying the mitotic spindle. Paclitaxel works by interfering with normal
Minchanka [31]

Answer:

by inhibiting the mitotic spindle plasticity

Explanation:

In eukaryotic cells, the mitotic spindle is the cytoskeletal structure by which sister chromatids are separated during cell division. Spindle microtubules are known to drive chromosome segregation, while tubulins are Microtubule-Associated Proteins (MAPs) that attach to microtubules in order to modulate their dynamics. Antimitotic drugs are nowadays widely used in chemotherapy to disrupt microtubule assembly and chromosome segregation, thereby producing mitotic arrest and cell death (apoptosis).

___ transport moves molecules across the plasma membrane of a cell with the help of transport proteins and energy (atp).
eimsori [14]

Active transport moves molecules across the plasma membrane of a cell with the help of transport proteins and energy (ATP).

Active transport is the means of transport of molecules across the plasma membrane with the help of energy. This method is usually used for the transport of molecule against their concentration gradient, i.e., from lower concentration to higher concentration.

Plasma membrane is the outer layer surrounding the cell. It is made up of lipid bilayer, proteins, carbohydrates and cholesterol. The lipid bilayer is amphipathic since the lipid head is hydrophilic and its tail is hydrophobic. The plasma membrane is semi-permeable in nature.

Retina, Iris, Pupil, Cornea, Lens, etc. How do these eye parts function?
Katena32 [7]

The functions of eyes parts are as follows:

Retina: The rays of light focused on the retina by the cornea and lens. The retina produces an image which is sent along the optic nerve of the brain.

Iris: It changes the size of pupil and allows different amount of life to enter the eyes.

Pupil: The light enters to the eyes through it.

Cornea: It forms the outer coating of the eyeball and covers the iris and pupil.

Lens:

Does an rh negative individual normally contain anti rh antibodies
fiasKO [112]
An Rh negative individual does not contain anti Rh antibodies. Rh- antibodies only develop in cases of pregnancy, miscarriage or a blood transfusion like if you have Rh-negative blood you got AB blood. The Rh-antibodies then work to attack the foreign substance, the RBCs. In the fetus, loss of RBCs means the rise of bilburin and could eventually lead to brain damage and also have low muscle tone.

Explain how a root hair cell is specialised for its function
katrin2010 [14]
Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption. They also contain lots of mitochondria , which release energy from glucose during respiration in order to provide the energy needed for active transport.
Hope this helps, have a nice day!:)
