Answer:
I remembered all of these. The information mentioned in the question describes the functions of components of a cell. All the cells in the body perform specialized functions but every cell contains almost the same organelles.
The nucleus is the organelle in which the hereditary material or DNA is present. Ribosomes are the protein manufacturing units of a cell. The golgi complex is involved in the packaging of the proteins. Vacuoles are the storage site of a cell. Mitochondria is the power house of the cell.
The correct answer is C. Controlled experiments
Explanation:
A scientific claim is a statement that describes or explains a phenomenon of the world. These statements can be proven as valid or invalid only through scientific experiments, which involve testing in controlled conditions the phenomenon. This is the only way because the scientific method should be followed. For example, if the claim is that humidity affects the growth rate of cacti. The researcher will need to use multiple cacti and use different percentages of humidity to prove if humidity increases or decreases the growth rate. Also, in this case, other factors such as nutrients in the soil, exposition to sunlight, etc. should be controlled to guarantee these factors are equal for all plants. According to this, the one that serves as evidence for the scientific claim is controlled experiments.
I would first measure the temperature of the water then measure the temperature of the water AFTER the sun go down .
Answer:
The correct option is A
Countercurrent multiplication is the process whereby energy is used to generate an osmotic gradient in which water is reabsorbed from the tubular fluid to produced concentrated urine.
Explanation:
Countercurrent multiplication moves sodium chloride from tubular fluid into interstitial space deep within the kidneys. The concurrent multiplication process build up osmotic gradient interstitial fluid in a single effect. Here, sodium chloride is driven by active transport out of the tubular fluid in the thick ascending limb into the interstitial fluid, which becomes hyperosmotic. This result to water moving passively down its concentration gradient out of the tubular fluid in the descending limb into the interstitial space to a point where it attains a state of equilibrium.
Therefore,the correct option is A, where the ions leaves the ascending limb to make water comes out of descending limb.
If the organism has no natural predators then that organism can start to overpopulate the habitat and use up valuable resources that other organisms, who DO have natural predators, need to survive and repopulate.
