Answer is C. The man is twenty thousand (2 x 10⁴) times larger than the paramecium.
1 meter (m) = 10⁶ micrometers (µm)
Therefore, 1.7 m = 1.7 × 10⁶ µm
Thus, the length of the man compared to the length of the paramecium will be
1.7 × 10⁶ / 85 = 2× 10⁴ .
Therefore, length of the man is 2× 10⁴ times larger than the length of the paramecium.
Typical cervical vertebrae have several features distinct from those typical of thoracic or lumbar vertebrae. The most notable distinction is the presence of one foramen, in each transverse process. These transverse foramina encircle the vertebral arteries and veins.
The answer would be c. This is because hormones are apart of the endocrine system and dispose of extra salt in the body. Helping with urinating is part of the excretory system.
Hope this helps :)
Answer:
d. CT scans of the fossilized skulls of Hobbits suggest they were probably microcephalic modern Homo sapiens.
Explanation:
The work of Falk et al in 2007 compared the CT of microcephalic humans skulls and normal humans skulls, finding the variables that allow them to classified with 100% success. When compared with the skulls of the ‘Hobbits’ of Flores, the size is similar to the microcephalic skulls in humans but the shape features sort it with normal humans skulls. They concluded that the ‘Hobbits’ of Flores are a separate species.
