Give one example of an extrinsic homeostatic mechanism overriding an intrinsic homeostatic process.

Biology
1 answer:
NeTakaya3 years ago
8 0

Answer:

Extrinsic regulatory mechanisms are external and depend on the firing of some factor outside the population itself. Among them are interspecific competition, food and space restrictions, very strong climatic variations, weathering and inharmonious relationships with other populations (parasitism and predatism).

Good examples of interspecific competition appear when rabbits, caves, rats compete for the same plant, or different fish and birds, such as the heron, vie for the same species of smaller fish. This is because these different species keep their populations in the same ecological niche. Competition is often so strong that some species eventually, as one example of an extrinsic homeostatic mechanism overriding an intrinsic homeostatic process is their disappearance or migration to other regions.

In this competition, the presence of adaptations among individuals in the population that promote better food search, speed, vision, and others can make the difference between elimination and survival.

Human papillomavirus (HPV) is a double-stranded DNA virus that enters the cytoplasm before undergoing uncoating. Although the vi
Roman55 [17]

Answer:

Basal cells, keratinocyte

Explanation:

The viral DNA replication is inhibited until<u> Basal cells</u>  are differentiated into <u>keratinocyte</u>, which are ready to be shed from the epithelial layer, increasing the likelihood that HPV will be transmitted to a new host.

95% of the cells in the epidermis are keratinocytes

Basal cells are multipotent stem cells that are important in the regeneration of homeostasis of the respiratory epithelial cell population.

in skin growth, most of the cells are keratinocytes and they are formed by the division of stem cells in the basal layer

É correto afirmar que a presença de lagartas em espigas de milho se deve:
slavikrds [6]

Answer:

C - ao desenvolvimento de ovos depositados por borboletas.

Explanation:

Antes de responder a sua pergunta, eu preciso te explicar que esse não é o servidor brasileiro e sim o servidor dos EUA, você deve ter percebido que toda a linguagem do site esta em inglês. Isso significa que você só deve postar perguntas em português no campo "World Languagens" mesmo que a sua pergunta seja de biologia como essa. Caso você não faça isso, a sua pergunta pdoe ser excluída, sem ser respondida.

As lagartas que surgem nas espigas de milho, são resultado do ciclo de vida da lagarta e refere-se ao momento em que os ovos depositados nas plantas de milho pelas borboletas se chocam, liberando as lagartas, que se desenvolverão e virarão novas borboletas.

É impossivel que um grão e milho vire uma lagarta, ou que o sabubo apodrecido pode gerar lagartas. Além disso, o ´processo de geração espontanea é uma teoria cientifica invalida e que não deve ser considerada.

xxTIMURxx [149]
<span>A woman who regularly misses meals is the most likely to have a child suffering from lowered birth weight.

Deserts typically have average daytime temperatures of around 100°F, while the average daytime temperature in tropical rain fore
Lelechka [254]

Answer: The temperature of the rainforest does not experience a drastic fall as in the case of the desert.

Explanation:

In the desert the average daytime temperature remains 100°F and that of the rainforest is 85°F. But average monthly temperatures are lower in the case of desert as compared to the rainforest although the vegetation cover is higher in rainforest as compared to desert so humidity is also more. During night in desert temperature drops to an average of 25°F whereas in rainforest during night temperature level does not drop much it drops to only 71°F. Therefore, the average monthly temperature on desert is lower than rainforest.
