The drug colchicine inhibits the formation of spindle fibers during mitosis. If you treat dividing plant cells with colchicine,
vekshin1

Answer:

D

Explanation:

During metaphase of cell division, the chromosomes line up in the metaphase plate and the spindle fibers from the poles extend and attach to the centromeres of the chromosomes. The spindle then contracts and pull different chromosomes to the opposite poles of the cell before the parent cell divides.   If spindle fibers do not form, then the chromosomes will not separate during anaphase.

Therefore, the final cell after mitosis will be a cell with double the number of chromosomes -because if you remember, during interphase, genetic material is replicated so each daughter cell can have its copy-. Due to quality control in the process of cell divisison, this cell will mostly undergo apoptosis, otherwise, it could develop into cancer.

Si una enfermedad comienza a provocar la muerte de las poblaciones de lagartijas en las islas, ¿en cuál de ellas es más probable
elixir [45]

Answer:

It is likely that the lizards that live isolated from the rest (maybe in the farthest island) have more chances to survive because the disease needs to enter into the lizard's habitat to attack these populations. However, it is important to note that we need to know which is the cause of this disease in order to establish a working hypothesis.

ddd [48]

A new animal is discovered that is more sensitive to pain in its toes than its fingers. If we were to examine the brain of this animal we would notice that <u>the</u><u> parietal lobe</u><u> would have more brain area devoted to the toes than the fingers.</u>

<h3>What is the parietal lobe's primary purpose?</h3>

The parietal lobe is one of the major lobes in the brain, roughly located at the upper back area of the skull.It is found on both the left and right hemispheres of the cerebral cortex.

Somatosensory information from the body, such as touch, pain, temperature, and the perception of limb position, is processed by the parietal lobes. The parietal lobes play a role in integrating data from several modalities, just like the temporal lobes do. Parietal lobe houses the primary somatic sensory cortex, a part of the brain that processes information from various parts of the body.
