The blood first leaves the heart through the <u>brachiocephalic trunk common carotid. </u>
Next it flows into the <u>aorta axillary,</u> which is found in the medial upper arm.
The <u>aorta axillary</u><u> </u>out of the three branches of the aorta takes blood to the right arm.
Blood going to the thumb would travel through the<u> subclavian</u> in the lateral side of the forearm.
After blood flows through the <u>radial</u> it flows into the <u>ulnar,</u> which is found in front of the scapula.
Explanation:
1. Brachiocephalic trunk carries blood from the left ventricle of the heart to branch arteries.
2. Aorta in the human body is the largest artery. It starts from the top of the left ventricle which is called the heart's muscular pumping chamber. The heart, therefore, pumps blood from the left ventricle into the aorta through the aortic valve.
3. Subclavian veins carry blood to the heart and their function is to empty blood from the upper extremities and then carry it back to the heart.
4. Radial bone is one of the two large bones of the forearm. It is located on lateral side of the elbow to the thumb side of the wrist and parallel to the ulna.<span>

Answer:
a) the molecules can be found in the picture below
b) (i) isocitrate lyase ( isocitrate to glyoxylate)
(ii) malate synthase (glyoxylate to malate)
c) Glyoxylate cycle do no exist in animals
Explanation:
b) in the glyoxylate cycle isocitrate lyase helps in conversion of isocitrate to glyoxylate. Also, helps in conversion of glyoxylate to malate by using malate synthase.
c) Glyoxylate cycle do no exist in animals, it only exist in plants and bacteria. This is because they can produce glucose from acetyl-CoA in required amounts.They have the ability to change acetyl-CoA from fat into glucose. But in animals, this mechanism is not possible.
Of course the major needs of a plant is CHLOROPHYLL, because chlorophyll makes the plant green then SUNLIGHT, because the process cant work without energy. Then WATER and CARBON DIOXIDE.
Hoping this could help
These limbs (see attached image) provide evidence of common ancestry because
they have the same basic structure. In evolution we have convergent evolution and divergent evolution; In convergent evolution we focus on the analogous structure; which have different ancestry but perform similar functions while in divergent evolution, we have homologous structures which have a common ancestry and similar structure; but performs different functions, like the limbs described above.
