The correct answer is option C, the concentration of the hydroxide ion is greater than the concentration of the hydronium ion
Reason -
An acidic solution has an ability to contribute hydrogen ion. Here a hydronium ion (H3O+) has an extra H+ ion along with a water molecule. Thus presence of hydronium ion in larger amount than the hydroxide ion would make the solution acidic. Thus, the concentration of hydroxide ion should be less than the hydronium ion to make the solution a basic solution.
Cellular respiration extracts energy from food and takes place in the organelle called a mitochondria.
It is made up of an outer membrane, an inner membrane, and a gooey matrix inside.
Mitochondria is also known as the "powerhouse". It is also involved in the Krebs cycle and oxidative phosphorylation phases of the respiration.
It is an oval-shaped organelle found in most of the eukaryotic cells. Its membranes are specialized for aerobic respiration. As the site of cellular respiration, mitochondria gets to transform molecules such as glucose into energy molecule known as ATP (adenosine triphosphate).
The electron transport chain and most ATP synthesis depends on the compartments created by the inner membrane of the mitochondria.

Answer:
substantia nigra
Explanation:
The Limbic system is a complex set of brain structures that can be seen on both sides of the thalamus. It supports a variety of functions including emotion, behavioral activities,motivation, memory e.t.c. It composition entails the hypothalamus, the hippocampus and the amygdala.
The hypothalamus which is located below the thalamus (i.e hypo means "under") helps to regulates thirst, body temperature, and sexual behavior, and helps maintain a steady (homeostatic) internal state of the body of an organism.
Hippocampus is the centre of memory.
Amygdala (an almond-shape set of neurons) play a key role in the processing of emotions.
On the other hand, The substantia nigra is a basal ganglia structure that can be seen in the midbrain. The substantia nigra plays a vital role in reward and movement. This area of the brain sends signals down the spinal cord to control the muscles of the body.
Answer;
-All blood types made compatible with each other
Explanation;
-In 1898, it was discovered that inherited differences in people’s red cells were the cause of many of the incompatibilities found with transfusions.
-During World War I, when human blood was needed for transfusions for wounded soldiers, studies began of how to preserve and transport blood and four blood types were identified.
