Mitosis simply refers to cell division in which one cell divides and produce two new cells that are identical.
Here are the steps:
(1) Prophase
<span>(a) Early prophase when cells starts to break down some structures and build others up. It sets up the stage when the chromosome is dividing.</span><span>(b) Prometaphase, mitotic spindle begins to capture and organize the chromosomes.
</span>
(2) Metaphase
<span>The spindle has captured all the chromosomes. They lined them up at the middle of the cell making it ready for division.
</span>
(3) Anaphase
<span>The sister chromatids separate from each other and are pulled towards opposite ends of the cell.
</span>
(4) Telophase
<span>The cell is nearly finished dividing, and it starts to re-establish normal internal structures as cytokinesis takes place.</span>

This is called maintaining homeostasis. The hypothalamus also maintains homeostasis in lots of other ways, such as by controlling your blood pressure. The temperature in your body, like the temperature in your home, is a balance between different cooling and heating systems.
Answer:
Absorben o excretan agua salada para mantener la homeostasis.
Explicación:
La regulación hídrica y salina en peces de agua dulce y salada se realiza según las condiciones ambientales. Los peces pueden pasar mucha orina muy diluida en la que hay menos solutos o sales, y logran el equilibrio de electrolitos en el cuerpo mediante el transporte activo de sales a través de las branquias. En un ambiente marino hipertónico, los peces de agua salada comienzan a beber agua de mar y mantienen el equilibrio electrolítico mientras excretan el exceso de sales a través de sus branquias y su orina.
Answer:
Pandas are a model whose species where close to wiped out yet was effectively turned around. The goliath panda has quite recently been downsized from 'Imperiled' to 'Powerless' on the worldwide rundown of species in danger of termination. The International Union for Conservation of Nature (IUCN) declared the positive change to the goliath panda's legitimate status in the Red List of Threatened Species, highlighting the 17% ascent in the populace in the decade up to 2014, when an across the country enumeration discovered 1,864 mammoth pandas in the wild in China.
Dangers to the mammoth panda incorporate living space misfortune, low paces of multiplication and chasing. A huge extent of the panda's territory has just been lost: logged for timber and fuel wood, or cleared for agribusiness and framework to address the issues of the zone's blasting populace. The Chinese government restricted signing in the panda's natural surroundings in 1998, however new streets and railroads are proceeding to slice through the district, further dividing the woodlands. This disengages panda populaces and keeps them from rearing. It additionally leaves them increasingly defenseless against bamboo kick the bucket offs. Bamboo normally ceases to exist each 40-120 years, contingent upon the sort. Before, pandas could relocate to new zones looking for nourishment, however these days that they are never again ready to 'follow' the bamboo.
Despite the fact that endeavors have been made to forestall the chasing of Pandas in China, they can even now be executed by poachers or in traps expected for different creatures.
The Giant Panda has been the focal point of one of the most escalated, prominent endeavors to recuperate an imperiled species. In 1981, China joined the Convention on the International Trade in Endangered Species (CITES), which made exchange of Panda skins illicit. Establishment of the 1988 Wildlife Protection Law prohibited poaching and gave ensured status to the Giant Panda (recorded as Category I, the most elevated level of security). The National Conservation Project for the Giant Panda and its Habitat of 1992 spread out a master plan for Panda protection and set up a Panda save framework, which today has developed to 67 stores. Augmented by over half since the Third National Survey, this hold framework presently ensures 67% of the Panda populace and about 1.4 million hectares of Panda. These endeavors to end poaching and ensure Panda living space assumed a huge job in Panda recuperation. The Chinese government likewise put resources into framework and limit working for hold staff, set up hostile to poaching watch, diminished human exercises inside stores, and now and again moved human settlements from inside to outside of stores.
