Are there any statements given for this assignment? Because according to what I know, alligators and crocodiles are more related to birds because of archosaurian origins. However, crocodiles are more closely related to birds than snakes because the evolution of birds from having snouts to beaks are slightly evident in crocodiles for they have more pointly snouts.
Sternal angle marks the joint between the sternum and the 2nd rib.
Option E.
<h3><u>Explanation:</u></h3>
Sternum is the breast bone which is a dorsi ventrally flattened bone present in thorax of human. It gives the support for the ribs where the ribs join. A sternum has three parts - Manubrium sterni, body of sternum and the xyphoid process.
The sternum has attachments of a total of 10 ribs and clavicle. The clavicle and the first rib joins in the Manubrium sterni, and the 3rd to 10th rib joins in the body of sternum. The 2nd rib joins in a facet which is partly in Manubrium sterni and partly in body of sternum. This place id also called the sternal angle. So the sternal angle marks the joint of 2nd rib to sternum.
a) ribosomes on the rough endoplasmic reticulum
mRNA (created by DNA) leaves the nucleus through the nucleic pores, and from there will enter a nearby ribosome since the rough endoplasmic reticulum is surrounding the nucleus. It is there that polypeptides are made and transported in vesicles to the Golgi apparatus because they cannot touch the cytoplasm when still incomplete. Hope this helped.
I'm assuming that you want us to tell you what organism does these things. So it would be a plant.
The type of asexual reproduction which is being represented is definitely C. Fission, because according to the data above the entity has divided into two or more parts which is a characteristics for the fission.
