Answer:
Mitochondrial DNA is inherited from the maternal side
Explanation:
Mitochondrial DNA is inherited from the maternal side (from the oocyte). The mitochondria from the sperm cell including their DNA are degrade after fertilisation.
The size of the cells that make the zygote also contribute to this. The oocyte is much larger than the sperm, containing around 100,000 mitochondria, whereas the much smaller sperm cell only contains around 100. This means even initially, there are very few paternal mitochondria compared to maternal mitochondria in the first place, effectively diluting them out.
This, coupled with the degradation of the sperm mitochondria, means that offspring will not inherit mitochondrial DNA and any mutations from their father.

Answer:
A longitudinal wave is characterized by COMPRESSIONS and RAREFACTIONS.
Explanation:
Answer: Direct proportion. The salinity of water in the ocean rises with higher temperature because water is evaporated from the ocean, leaving more solutes (salts) in it.
i hope this helps you if it does please mark brain list i really need it to level up :)
Fishes and bottom dwelling worms cope with the fluctuating salinity within estuaries over the tidal cycle with the use of transport system such as active and passive transport.
<h3>How active and passive transport system are used?</h3>
In salty water, fish and other marine organisms used active transport in which energy is used to remove salts from the body of these marine organisms because excess salts are harmful for them.
So we can conclude that Fishes use transport system such as active and passive transport to cope with the fluctuation of salt concentration.
