Ansywer: (C) The hypothalamus is located in each endocrine gland to help regulate functioning.
Explanation: Hypothalamus is located at the base of the brain lying below the thalamus (in the third cerebral ventricle).
Hypothalamus is connected to pituitary gland and both modulates transmission of stimuli. It also regulates internal functioning in response to external stimuli and other functions.
Thus, all the above options are correct EXCEPT “it is located in each endocrine gland to help regulate functioning”.
Answer: Mechanical weathering breaks rocks into smaller pieces without changing their composition and chemical weathering breaks down rocks by forming new minerals that are stable at the Earth's surface.
The superior vena cava (SVC) is the superior of the two venae cavae, the great venous trunks that return deoxygenated blood from the systemic circulation to the right atrium of the heart. It is a large-diameter (24 mm), yet short, vein that receives venous return from the upper half of the body, above the diaphragm.
<h2>Answer:</h2>
Option B is correct.
B. aerobic autotroph
<h3>Explanation:</h3>
Autotrophs are organisms that can produce their own food from the substances available in their surroundings using light (photosynthesis) or chemical energy (chemosynthesis).
So, if a particular single-celled organism uses radiant energy to fix carbon as sugars and generates ATP by breaking down sugars through a process that uses oxygen, then it will be an
aerobic autotroph.
A proton has a positive charge and is in the nucleus.
