Answer:
The four most abundant elements in the human body – hydrogen, oxygen, carbon and nitrogen – account for more than 99 per cent of the atoms inside you. They are found throughout your body, mostly as water but also as components of biomolecules such as proteins, fats, DNA and carbohydrates.
Fats is the ideal source of energy for prolonged, low-intensity activity. fats helps increased the blood flows through adipose tissue that is used during the prolonged exercises.
The direction will be toward the positive charge on the other end. If there are bubbles it means the current is running. DNA are molecules which stores genetic material. DNA is negatively charged because of the phosphate backbone since they are negatively charged also. To separate DNA using agarose gel electrophoresis, the DNA is loaded into precast wells in the gel and a current applied. Since the phosphate backbone of the DNA molecule is negatively charged, the fragments of DNA will migrate to the positively charged anode.
Answer:
-The cerebral cortex, also known as the cerebrum, is the largest portion of the brain, located right under the forehead and it is divided into two parts, a right and a left hemisphere. They in turn have a total of four lobes – the frontal, parietal, temporal and occipital lobes. The cerebral cortex controls movement, speech, memory and intelligence.
-The amygdala is an almond-shaped mass of nuclei (mass of cells) located deep within the temporal lobes of the brain. There are two amygdalae, one situated in each brain hemisphere. The amygdala is a limbic system structure that is involved in many of our emotions and motivations, particularly those that are related to survival. It is involved in the processing of emotions such as fear, anger, and pleasure. The amygdala is also responsible for determining what memories are stored and where the memories are stored in the brain. It is thought that this determination is based on how huge an emotional response an event evokes.
-Hippocampus, region of the brain that is associated primarily with memory.
-The hypothalamus is a small region of the brain. It’s located at the base of the brain, near the pituitary gland.
Answer:
Vitamin C is the independent variable and problem solving performance is the dependent variable.
Explanation:
The independent variable is the variable that can be manipulated or changed to measure its effect. Vitamin C dosage can be changed for difference individuals to see the effect on their problem solving performance.
Dependent variable is the variable on which the effect of independent variable is measure i.e the effect of vitamins C with different dosage will be known or measured base on problem solving performance of an individual.
Therefore ability to solve problems by individual after the intake of vitamin C means its depends on Vitamin C intake.
