The smallest structural and functional unit of an organism is a cell.
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:
C. inhibiting the breakdown of neurotransmitters in the brain
Explanation:
Monoamino oxidase (MAO) facilitates the break down and removal of neurotransmitters like nor-epinephrine, epinephrine, serotonin in brain which have excitatory effects on neurons. When these neurotransmitters are degraded by MAO, this would lead to decreased excitatory level of neurons and it will become less functionable as seen in most of the patients suffering from depression, panic disorders, social disphobia and some neurodegenerative disease.
Monoaminooxidase Inhibitors prevents the degradation of above mentioned neurotransmitters which leads to increasing their levels and concentration which allows them to work and influence on neurons effected by depression.
Answer: The hypothesis can be completed as-
If the type of food available changes, then the frequency of beak also changes.
Explanation-
Natural selection is a theory of evolution that was given by Charle's Darwin. According to this theory, organisms that are capable of adapting themselves ( that is having beneficial traits, which enhance their survival) in the changing environmental conditions survive and increase their number by means of reproduction.
According to the information given in this question, the type of food available is changing, which will result in the change in the frequency of bird beaks inhabiting that area. This would indicate their adaptation so as to survive under the changed food type, otherwise they will be unable to consume the food resources and will die out.
