Answer:
Through chemical reactions.
Explanation:
You tell if an unknown powder is salt, sugar, flour or baking soda by doing tests to see how the powder would react. For an example, baking soda in vinegar would cause it to fizzle, while flour would just make the vinegar murky and cloudy. With salt and sugar, you can test if it dissolves and if it does it is sugar. If not, it is salt.
Answer:
Answer is true.
Explanation:
A systemic circulation involves the supply of functional blood which is known as the oxygenated blood to cells or body tissues, and subsequently picks up carbon [iv] oxide and other waste products.
The erythrocytes are the red blood cells which when mixed with oxygen become bright red in color.
Note that, systemic tissues are where the oxygen from the heart are being released and the waste products are absorbed.
Answer:
This question lacks options, the options are as follows:
A. formation of ATP from glucose during respiration
B. formation of carbohydrates from carbon dioxide during photosynthesis
C. formation of oxygen from water molecules during photosynthesis
The answer is A. formation of ATP from glucose during respiration
Explanation:
Oxidation reaction is a type of reaction that involves the loss of electrons (e-) by a compound or molecule. The compound/molecule that loses the electron is said to be OXIDIZED.
According to this question, Chris is studying oxidation and reduction reactions (redox). An example of oxidation reaction she could use is FORMATION OF ATP FROM GLUCOSE DURING RESPIRATION. Glucose (C6H12O6) undergoes series of oxidation reactions in glycolysis, Krebs cycle and ETC, as it loses electrons to eventually produce energy (ATP).
<span>The ovaries produce estrogen and progesterone in women. Both play an important role in the menstrual cycle: estrogen stops FSH production and stimulates LH release by the pituitary gland. Progesterone maintains the uterus’ lining. Men also produce estrogen, though at lower levels, and this is done through changing testosterone into estrogen with an enzyme.</span>
