plz help! explain how science uses fossil evidence to support the theory of evolution. ​(I will mark brainliest)
vagabundo [1.1K]

Answer:skeletal evidence of evolution

Explanation:

So I’m not sure the best way to explain this, will edit in one second

So basically some creatures have leftover bones or other features that have no benefit but they also aren’t detrimental, and they are the result of evolution. There is a great video on bad animal skeletons by Sam O Nella Academy, it has some strong languages so inappropriate jokes, probably, all of them do, and this is middle school biology so watch at your own risk, but I think a pint you could bring up that your teacher would be impressed by is really any animal with a weird skeleton, for example dolphins who just have a random bone image where their legs used to be, they obviously don’t have legs but their ancestors did and to this day they still have a random bit of bone where an ancestor of theirs used to have legs, so skeletons help connect what a common ancestor looked like to what the current species looks like through similar bone structure and/or left over bones, such as dolphins who have a plate where an ancestor used to have legs

D) differences between species and their ancestors

This is because of the adaptive mechanism and mutations the organisms have to respond to. <span>Adaptation processes occur to help species survive and thrive in the ecological balance of life. Structural adaptations are physical features of an organism that adapted through time. An example of this are the bills of a bird and the fur of bears that they generally need for their survival; birds for hunting, and bears to protect them from low climate areas.</span>

Which of the following correctly identifies the main function of photosynthesis?
Liono4ka [1.6K]

Answer: The correct answer is- Converts solar energy to chemical energy.

Photosynthesis is a process of formation of food by green plants and algae using CO₂ and H₂O in the presence of sunlight. In this process, energy from sunlight is absorbed by chlorophyll ( green pigment present in the chloroplast) and it is converted into chemical energy in the form of ATP and NADPH. This is further utilized in the formation of food that is a carboydrate ( glucose).
