Answer:
Option A
Explanation:
Only an autotrophic species can convert methane into food.
Deep below the sea, methane and hydrogen sulfide are found in abundance. These gases get mixed into the sea water.
Autotrophic bacteria containing phosynthetic pigments oxidize these dissolved gases thereby producing food.
Hence these autotrophic bacteria’s will be considered as producers as they produce food.
Thus, option A is correct.
Answer:
Vestigial structure. Hope this helps :P
Explanation:
The kinesthetic system relies on receptors in the vestibular nerve to relay information to the brain.
<h3>What is vestibular nerve?</h3>
- The vestibular nerve transmits motion and positional information.
- The vestibular apparatus, ocular muscles, postural muscles, brainstem, and cerebral cortex all communicate with each other in unison as part of the vestibular system.
- The vestibulocochlear nerves have two main categories of unique sensory function.
- The cochlear nerve controls hearing, while the vestibular nerve controls balance and equilibrium.
- The vestibule and cochlea, which are monitoring receptors in the inner ear, are the origin of the vestibulocochlear nerves.
- The most likely causes, according to researchers, are viral infections of the inner ear, swelling around the vestibulocochlear nerve, or viral infections that have already spread to other parts of the body.

The question is incomplete. The complete question is:
Question: Select the correct statement about the special fetal blood vessels.
A The umbilical vein becomes the ligamentum teres.
B The distal parts of the umbilical arteries form the superior vesical arteries.
C The hepatic portal vein forms from the umbilical artery.
D The fossa ovalis becomes the f
oramen ovale.
Answer:
C) The umbilical vein becomes the ligamentum teres.
Explanation:
After birth, many vascular changes occur in the newborn child as the pulmonary, renal and digestive systems start functioning. As the umbilical cord is tied off and severed, the blood does not flow through the umbilical arteries. The umbilical vein in the child collapses but remains as the ligamentum teres. Ligamentum teres is a round ligament and serves to attach the umbilicus to the liver. It is present in the free border of the falciform ligament of the liver.
