Answer:
They have uncoiled to form long, thin strands.
Explanation:
Chromosomes are present in cell nucleus and consist of chromatin. Genes are present in linear order on chromosomes. The chromosomes become visible under the microscope as distinct structures during cell division. When cells are not dividing, the chromosomes decondense to loose their individuality and make the mass of chromatin.
Chromatin is complex of DNA and packing proteins. As the cells enter the prophase stage of cell division, condensation of chromatin occurs and individual chromosomes become visible under microscope. Before that (during interphase), chromosomes are not visible as they are present in decondensed form.
All of the above.
They can be prevented, especially Polio.
Smallpox is common in children, but potentially deadly in baby's.
Influenza is the flu.
There are a lot of forest management practice that cause harm to the forest ecosystems. On of the most harmful is Clearcutting. Also known as clearfelling, in this forestry almost or all of the trees are cut down. It is synonymous to deforestation. It destroys natural habitats.
The arched nucleus is the center of food control and appetite inhibition, if it is stimulated by a tumor, then the person will not be able to eat (loss of appetite).
The axons of the neurons, located in the ventrolateral region of the arcuate nucleus, form what is called the tubero-infundibular pathway that delivers dopamine into the hypothalamic-pituitary portal system.
Pituitary glandular cells that have dopamine receptors will then reduce their release of prolactin, a hormone that has several effects:
*sensation of well-being after orgasm in both males and females (Luca will have this effect).
*growth of the mammary glands and milk production in women.
