Answer:
Membrane proteins perform a variety of functions vital to the survival of organisms: Membrane receptor proteins relay signals between the cell's internal and external environments. Transport proteins move molecules and ions across the membrane.
Explanation:
they help transport some substances through the membrane.
-DNA is double stranded,RNA is one stranded
-DNA contains the following nitrogenous bases:Adeninde Guanine Timine Citozine while RNA contains Adeninde Guanine Citozine and Uracil
-DNA function is to contain the information for manufacturing proteins while there are many types of RNA with whole different jobs for example:messanger RNA(mRNA) it coppies a sequence from the DNA strand and takes it to the ribosome in order to be translated as the order for placing aminoacids in the polypeptide strand;transport RNA(tRNA) it is a short RNA strand containing up to 100 nucleotides it takes aminoacids to the ribosome so the polypeptides strand can start to be manufatured from aminoacids in an order inscripted in the mRNA.

anatomy that focuses on body structures that are visible to the naked eye is
called gross anatomy. It is only concern with macroscopic details and therefore
do not need any aid of instrument. Gross anatomy is used to study dead bodies
that uses two approaches. The systemic approach, studied the different system
of the body while in regional approach, human body is studied in different regions. </span>

<u>Answer:</u>
Fossils are the sources to learn the changes on the earth and how much it changed in these years. Its provides us with information about the existence of plant and animals in the past.
Actually, the fossils we found till the date are the ancestors of the plants and animals that live today. Moreover, some fossils of animals are easily identifiable since they exist till the date.
But there are fossils of animals that exist no longer in the earth. By studying and analyzing the fossils, one can tell how life on the earth has changed.
Also, we can learn about the ancestors of the plants and animals and how their long life existed on earth.
In other words, one can learn where and how those organisms were lived. So that we can know about our ancient environments.
