We determine the mass of the metal in grams by weighing it using the balance.
Next we obtain the volume of the metal by measuring its displacement with a graduated cylinder and water in the following way:
1.measure amount of water in the graduated cylinder.
2. Place metal into the graduated cylinder
3. Measure the amount of water in the graduated cylinder
4. Subtract step 1 from step 3. The difference is the metal's volume.
Once we have found out the mass and the volume then we calculate the density using the formula:
Density = Mass/Volume.
We then check our answer from the known densities of metals in the table of densities that has been provided and determine the identity and purity of the metal by how close our answer is to the most probable value in the table.
Answer:
<u>d</u>
Explanation:
Water enters the atmosphere by :
⇒ liquid water evaporates from lakes when heated by the Sun
⇒ frozen water sublimates from ice and snow
⇒ liquid water is lost from tree leaves during evapotranspiration
Answer;
Retinohypothalamic path
A small branch of the optic nerve, known as the retinohypothalamic path extends directly from the retina to the SCN.
Explanation;
The SCN is an abbreviations for suprachiasmatic nucleus or nuclei; which is a region in the hypothalamus. that is responsible for controlling circadian rhythms.
Retinohypothalamic path is a neural input pathway that extends directly from the retina to the SCN.
The suppression of glycolysis is responsible for a large portion of the control of gluconeogenesis.
Discussion about the statement:
The cytosol is the site of all glycolysis and gluconeogenesis processes. The rate at which glucose is produced in the body is inversely related to the intake of carbohydrates. The suppression of glycolysis is responsible for a large portion of the control of gluconeogenesis.
Fructose 2,6-bisphosphate is an intermediate that plays a crucial role in controlling both glycolysis and gluconeogenesis. This metabolite's presence can promote glycolysis and prevent gluconeogenesis.
Control of Gluconeogenesis and Glycolysis
- At various crucial stages of glycolysis and gluconeogenesis, metabolic control takes place. The catalysts that accelerate each of these stages can be activated or inhibited by outside forces, for example, the quantity of a molecule that comes after. The conversion of glucose and ATP into glucose 6-phosphate is the first controlled step in glycolysis. Keep in mind that hexokinase catalyzes this process.
- High levels of blood glucose, AMP, and low levels of cellular ATP all trigger the activation of hexokinase. In other words, the glycolysis process is enhanced when blood glucose levels are high. Whenever cellular ATP levels are low and AMP levels are high, glycolysis is also increased. Both of these instances show that the cell is short on energy and may be directly influenced to create additional energy.
