Hello there. :')
<span>When is cladistics more useful than Linnaean taxonomy?
</span><span>D.When you want to know ancestral relationships

The chloroplasts had inner membrane
Explanation:
The primitive photoautotrophs utilized hydrogen sulphide as the electron donor to perform photosynthesis for energy production.
Later upon understanding the endosymbiotic relationship of cyanobacteria which resided in the mitochondria of a eukaryotic host cell, the use of chloroplasts for photosynthesis was understood.
Generations after generations led to the development of chloroplasts by the cyanobacteria due to this symbiotic relationships which developed into the chloroplasts.
The unique presence of the inner membrane and its components like the stroma, thyllakoids helped the organism to utilize water as the electron donor for photosynthesis like the present day eukaryotes. This is the main reason why cyanobacteria is considered as the ancestor for eukaryotes.
Answer:
C. right side of the head and neck and right upper arm
Explanation:
The arch of aorta is a continuation of ascending aorta and terminates at the intervertebral disc of fourth and fifth thoracic vertebrae. The superior part of the arch of aorta branches off into three major arteries. The first branch of arch of aorta is the largest branch and is known as the brachiocephalic trunk.
The brachiocephalic trunk divides and forms the subclavian artery and right common carotid artery. Right common carotid artery supplied blood to the right side of the head and neck while the right subclavian artery delivers blood to the right upper limb.
Hence, any blood clot in the first branch of arch of aorta, that is the brachiocephalic trunk would affect the blood supply to the right side of the head and neck and right upper arm.
The vascular system of the plants are responsible for transporting water and needed nutrients for the plant to survive. Hence, when this is disturb certain transpirational pull is also disrupted, rendering the plant unable to collect water effectively. Thank you for your question. Please don't hesitate to ask in Brainly your queries.
Albert Einstein: Devout in his youth, Einstein's knowledge and appreciation of science led him to reject the Bible's miracle-producing God. I do indeed hope this helps.
