Answer:
Does not take up the stain.
Explanation:
Negative staining refers to the process wherein the unstained specimen is visualized under the darkly stained background.
One of the examples is capsule staining wherein the capsulated cells are stained with India ink or nigrosin dyes. The particles of these dyes stain the background blue-black but cannot enter the capsule.
Hence, the light-colored capsulated cells are visualized in the midst of the blue-black background.
Answer:
As a general rule, if you're in the Northern Hemisphere, look towards the southern skies to see the galactic core. This can be southeast (Spring), due south (Summer), or southwest (Fall) depending on the time of year. As mentioned above, Sagittarius is found nearest the galactic core.
Explanation:
I think that about half of all babies are able to walk independently by 12 month of age. It said that babies tend to take their first steps from the age of 9. Babies usually start to crawl before they can walk. This is because their arm are usually more effective. After crawling they learn to stand up with their feet first and later learn to walk while holding things. The next step after that is walking.
Not all babies walk at the same time. There those that learn before the other so there is no need to worry if your child does not walk by 12 months.
Identical and obviously duplicated gene sequences have gotten from one chromosome to another by chromosomal translocation.
In terms of genetics, a translocation takes place when chromosome fragments and the (often two) fragmented portions reassociate with other chromosomes. For the diagnosis of several genetic diseases and syndromes, the finding of chromosomal translocations can be crucial.
Multigene families are groups of related or identical genes that have developed by gene duplication. It is thought that a single ancestral gene was duplicated and varied to create multigene families. The multigene families that code for actins, hemoglobins, immunoglobulins, tubulins, interferons, histones, etc. are a few examples.

Answer:
Si, esto es lo que se conoce como circulacion menor.
Explanation:
La sangre cumple un recorrido en el corazon a la cual se la llama circulacion mayor, una vez que se continua su camino hacia los pulmones ahi ya pasa a ser circulacion sanguinea menor.
Estas circulaciones estan sumamente coordinadas y tienen un orden ritmico, con un unico fin, que es oxigenar la sangre que se recolecta de todo el organismo.
Es asi como la sangre que viene con CO2 entra a los pulmones posterior a la eyeccion cardiaca y cumple con el proceso de homeostasis en el alveolo y se oxigena.
