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
The answer is endocrine system. It includes all of the glands of the body and the hormones produced by those glands. The glands are controlled directly by stimulus from the nervous system as well as by chemical receptors in the blood and hormones produced by other glands. By regulating the roles of the organs in the body, these glands help to continue the body’s homeostasis. Cellular metabolism, reproduction, sexual development, sugar and mineral homeostasis, heart rate, and digestion are amid the several processes controlled by the actions of hormones.
Answer:
An increase in the number of H+ ion in the lake with many aquatic would cause cell shrinkage by the removal of water from the cell.
Explanation:
Every organism tries to maintain a constant PH inside their body to regulate the homeostasis of their body.
An increase in the number of H+ ion or proton in a lake will increase the osmotic pressure of the water present in the lake.As the osmotic pressure of Lake"s water is increased it will draw water out from the the cells of aquatic organism causing the cells to shrink thus decreasing the volume of the cell and if the H+ ion concentration rises at a high level cell death can occur.
Answer:
Same Phase at room temp
Explanation:
Here we have a metal and two nonmetals (sulfur and iodine).
They are all solid at room temperature. Metals form cations and are good conductors of electricity. They are not from the same family, therefore, they do not have the same number of valence electrons.
A couple of the methods of molecular biotechnology are cloning and recombinant DNA.
