At one time, Chondrichthyes were thought to have diverged from other vertebrates before the evolution of bone. Now we have concl
Ray Of Light [21]

Answer:

The correct answer would be - Characteristics can be lost in evolution.

Explanation:

The new evidence helps in developing a new hypothesis. In this case, new evidence proved that the Chondrichthyes diverged after the evolution of bone had started instead of before the evolution started. This process called atavism where an ancestral genetic trait reappears after having lost. This leads to loss of the traits in the evolution

This can take place by knocking the mutation out to overriding the gene by the old gene or overriding the new trait by the old trait during the evolution period.

Agata [3.3K]

Answer:

As with sea horses, sea dragon males are responsible for childbearing. But instead of a pouch, like sea horses have, male sea dragons have a spongy brood patch on the underside of the tail where females deposit their bright-pink eggs during mating.

How many years might primary succession take with medium amounts of rainfall and temperature? Explain why ​ HELPP PLEASE HELP
serious [3.7K]

Answer:

The primary succession process can take hundreds of years to happen, even in medium amounts of rain and temperature.

Explanation:

The primary succession occurs when a community of plants begins to sprout in areas that have never been occupied by any type of living being. The primary succession occurs, for example, with the sprouting of vegetables in rocky outcrops. These plant species are known as primary species and although they are able to survive, these environments offer few resources for the development of living things. Generally, it takes hundreds and even thousands of years for primary succession to occur, even in environments with average temperature and precipitation.

Why is mechanical digestion and important to chemical digestion
dangina [55]
They are both important because mechanical has to do with physical - cause mechanical means physical, so chewing your mouth is physical (you break your food into smaller pieces physically). And then chemical digestion is when food and saliva mix together. They happen when breaking down food into nutrients - enzymes. Enzymes are important for that process, because they make a nutrient.



Hope this helps!!
