Answer:
dilation of vessels and sweating
Explanation:
The vast blood supply of the skin aids in temperature regulation: dilated vessels enable heat to escape, while constricted vessels retain heat. The blood supply of the skin regulates body temperature. The skin aids in the maintenance of homeostasis. Humidity has an effect on thermoregulation because it reduces perspiration evaporation and, as a result, heat loss.
Answer:
The fossil record supports a "biological" type of evidence.
Explanation:
<u>Fossils-</u> this refers to the <em>remains of prehistoric organism.</em><em> </em>It provides a trace of a <em><u>once-living plant, animal or organism. </u></em>
When it comes to evolution, fossils provide a biological type of evidence. This means that,<u><em> it shows how organism have greatly changed from the past.</em></u> When you study fossil records, you can compare it with the animal, plant or human structure nowadays. You can compare them side-by-side. So, you'd get that idea on how prehistoric things lived in the past and how they evolved up to the present day or became extinct.
<em>Most of the fossils can be found on sedimentary rocks.</em> You can also tell their ages according to which layer they belong. It is said that older layers consist of older fossils and they appear at the bottom while younger layers consist of younger fossils and they appear on top.
