When an object turns around it’s internal axis (the earth turns on its axis) its a rotation. When an object turns around an external object (earth going around the sun) is a revolution.
Mitochondria and chloroplast have similar DNA, which is not evidence for the endosymbiotic origins of mitochondria and chloroplasts.
According to the endosymbiotic theory, a chloroplast and a mitochondria were the independent prokaryotes. Both can be ingested by a large prokaryote and resist digestion. As a result, they continued as endosymbionts and eventually lost some of their autonomic properties. They divide by binary fission, have their own genetic material, possess 70s ribosomes, and Both include their own transcriptional and translational machinery.
Therefore, considering endosymbiotic origin theory, Both Mitochondria and chloroplast have similar DNA is not a piece of evidence.

It
is False. The skin cancer that is most likely to metastasize is not the cancer
of melanocytes instead, it is known as the squamous cell carcinoma.
<span>Squamous
cell carcinoma is usually malignant in growth and develops from the scale-like
epithelial tissue. This kind of growth
is the most potential for the metastasis to the lymph nodes, which is now known
as the squamous cell carcinoma. This
type of cancer usually becomes more severe due to the excessive exposure to the
sunlight.</span>
<span>However,
malignant melanoma from melanocytes is considered as the most deadly kind of
skin cancer and is usually hereditary in origin. This cancer is more common in men redheads
and is usually treated surgically.</span>
