The isotope silicon-32 decays into phosphorus-32. Silicon-32 has a half-life of 170 years and can be used to find the age of roc

ks it is contained in. Which two statements are true regarding this scenario? PICK TWO
A) Silicon-32 is the stable daughter isotope and phosphorous-32 is the unstable parent isotope.

B) In a given rock sample, the amount of silicon-32 isotope gets divided in half about every 170 years.

C) The half-life can be used to determine the amount of silicon-32 that has decayed from the time the closure temperature was reached.

D) In a given rock sample, as the amount of silicon-32 lessens, so does the amount of phosphorous-32.

E) In a given rock sample, the amount of silicon-32 is always equal to the amount of phosphorous-32.

The correct answers are B & C. Silicon-32 is the parent isotope, which decays into phosphorus-32 (daughter isotope). The silicon-32 amount is halved every 170 years, so we can use this to determine how old the rock is. The amount of phosphorus-32 increases over time, but it is not equal to the amount of silicon-32.

Answer:

The answer is- A bundling relationship

Explanation:

Bundling is defined as when a company packages some of their products or services together as a single combined unit, often for a lower price than they would charge the customers if the items are sold independently or separately. This helps to facilitate the convenient sale of products or services from one company.

An example could be if Oral-B decides to sell both their toothpaste and toothbrush together as a single combined unit at a lower price than if selling the toothpaste or toothbrush separately.

BioMark Lifesystems' arrangement with the producer of syringes and test tubes to have diagnostic substances sold to laboratories in a package along with the syringes and tubes is called bundling relationship.

The ATP molecule shown is the universal energy source for cellular activities. Which of these processes is used to break down gl
sveta [45]
Let's do this by process of elimination: A cannot be the answer because glucose is broken down, not built up or synthesized. B is ruled out for the same reason. D is incorrect because transpiration results in water loss, not energy gain. The only correct answer choice is C respiration, specifically by the process of substrate-level phosphorylation during glycolysis in order to break down glucose into two pyruvate molecules and two net ATP

Explain how ligand A and ligand B can cause identical cellular responses in a cell?
Alexus [3.1K]

Answer:

Ligand A and ligand B can cause same cellular responses in a cell when they are attached to different receptors.

Explanation:

If two same ligands are attached to two different receptors, two different responses will occurs. Such type of response is present in acetylcholine, while when two different ligands attached to two different receptors, same response will occur. This type of response is present in glucagon and epinephrine etc. ligands are responsible for controlling the transcription process when it binds or attached to the DNA molecule of the cell.
