Answer:No. This does not qualify as homeostasis because homeostasis involves the control of a physiological variable within very narrow limits so that cells can function. The body temperature of a fish fluctuates with the temperature of the external environment.
Explanation:
Fishes are poikilothemic;therefore thier body temperature fluctuates with the external environment. If the fish stays in a preferred environment momentarily, this will influence its body physiological mechanism at that moment.
Once it leaves the spot its body physiological mechanisms returns to that of the new environmental temperature,therefore fluctuating with changes of the environment.
Since homeostasis refers to a relatively constant internal environmen of an organism, prefered temperature phenomenon cannot be homestatis.!!
In biology or human geography,population growth is the increase in the number of individuals in apopulation. Global human populationgrowth amounts to around 83 million annually, or 1.1% per year. The globalpopulation has grown from 1 billion in 1800 to 7.616 billion in 2018.
Answer:
Nucleus
Explanation:
The nucleus is the organelle that contains the genetic material of eukaryotic organisms. That is, the DNA is contained in the nucleus while RNA is formed in the nucleus and transported out of the nucleus into the cytoplasm. This means the DNA and RNA can be present in the nuclues at the same time.
Answer: 10 cm
Explanation:
The water at 10 cm has the biggest survival rate for the embryos with ultraviolet B protection as compared to that of embryo which are not protected by UV-B.
Ultraviolet rays can be very harmful as it can reach the fetus but due to some particles present in water the intensity of UV-B becomes attenuated below 10 cm of water.
So, the correct answer is 10 cm.
Some examples are alcohol fermentation, lactic acid fermentation and in decomposition of organic matter.
