A mitotic inhibitor chemotherapy drug would  cause the DNA to break during the early stages of cell division. Mitotic inhibitors are drugs derived from natural plant sources, and work by inhibiting cell division or mitosis, where a single cell divides into two genetically identical daughter cells. They may bind to tubulin and inhibit its polemerization into microtubules.

Describe the relationship between biotic and abiotic factors in marine ecosystems.
inysia [295]
Biotic factors include plants, animals, microbes, etc. The important abiotic factors include the amount of sunlight in the ecosystem, the amount of oxygen and nutrients that is dissolved in the water, temperature, etc. Sunlight is one of the most important abiotic factors for marine ecosystems.

Classify the given terms or examples with the appropriate category
Alja [10]

Answer:

The cells of the ear detect these the position of the head: proprioceptors are guided in the hydrostative pressure and the movement of the intracochlear fluid with the movement. That is why it complies with the following statements: Sensitivity remains constant, Responds to change (we say that it responds to change because when changing position the intracochlear fluid is where the movement of the head is perceived).

The proprioceptors of the epithelial cells (MERKEL CELLS. THEY ARE THE ONLY SENSORY CELLS TOGETHER WITH THOSE OF LANGERHANS), are proprioceptors that capture different textile textures that contact the skin. But throughout our lives this sensitivity decreases, that is why it complies with the following statements: Responds continuously, Sensitivity decreases over time, nociceptors continuously detect pain (to be able to perceive if the innate protective barrier that is epithelial continuity is damaged, since in the face of damage or discontinuity due to a cut or injury we are unprotected by the innate epithelial defense barrier).

Explanation:

I hope the answer has served you, the body's proprioceptors are everywhere and are receptors specialized in capturing very fine stimuli, that is why they are considered proprioceptors with a very low uptake threshold.

The textural propipceptors that are epithelial, or pain, are different from those found in the ear.

if a child had O type blood and the mother had B type blood and the father had A type blood, could a blood test eliminate the fa
vladimir2022 [97]

Answer:

No, a blood test could not eliminate the father.

Explanation:

The mother had B type blood, so the possible genotypes are BB and BI.  The father had A type blood, so the possible genotypes are AA and AI.  The child had O type blood, so the only possible genotype is II.  If the mother has the genotype BI and the father has the genotype AI, then there is a 25% chance the child will have the blood type O, or II (I used a punnet square with the genotypes BI and AI to solve this.)

Arrange the following events in the proper sequence:
Illusion [34]

Answer:

Proper sequence of events:

5. Sensory receptor detects change in the environment.

2. Afferent neuron graded potential reaches threshold and fires an action potential.  

4. CNS reaches decision about response.  

1. Efferent neuron graded potential reaches threshold and fires an action potential.  

3. Target organ responds.  

Explanation:

Sensorial information is received by the peripheral nervous system and processed by the central nervous system. There are three types of neurons involved in this transmission: sensory or efferent neurons, interneurons, and motor or efferent neurons. First <em>stimulus energy is received</em> by sensory receptors specialized in responding to <em>different stimuli</em>.  Then it occurs the <em>transduction or conversion</em> of the stimulus energy (chemical, temperature, light, pressure, etc.) to action potential energy. The afferent neurons, located in dermis and epidermis, <em>receive information</em> from the sensory receptors, react to stimuli and <em>transmit impulses</em> to the central nervous system. This pathway is defined as the <u>ascending pathway</u>. Information is <em>processed</em> in the central nervous system by the <em>interneurons</em> which handle many sensory signals, evaluate them, compare them and use them for <em>decision making.</em> After that, an efferent neuron is stimulated to <em>carry signals</em> from the central nervous system to the <em>effectors' cells</em> of the target organ. The effector may be muscle or glandular tissue. This pathway is defined as the <u>descending pathway</u>. Finally, the target organ responds by contracting or hormone-releasing.

What layer of the retina contains photoreceptors?
Salsk061 [2.6K]

The rod and cone layer (bacillary layer) contains the inner and outer segments of the rod and cone photoreceptors cells. The pigment epithelium is the most external layer of the retina.
