What nucleus is the final product

Explanation:

In nuclear physics, a decay product (also known as a daughter product, daughter isotope, radio-daughter, or daughter nuclide) is the remaining nuclide left over from radioactive decay. Radioactive decay often proceeds via a sequence of steps (decay chain). For example, 238U decays to 234Th which decays to 234mPa which decays, and so on, to 206Pb (which is stable):

{\displaystyle {\ce {^{238}U->}}\overbrace {\underbrace {\ce {^{234}Th}} _{\ce {daughter~of~^{238}U}}{\ce {->}}\underbrace {\ce {^{234\!m}Pa}} _{\ce {granddaughter~of~^{238}U}}{\ce {->\cdots ->{^{206}Pb ^{\ce {decay~products~of~^{238}U}}}{\displaystyle {\ce {^{238}U->}}\overbrace {\underbrace {\ce {^{234}Th}} _{\ce {daughter~of~^{238}U}}{\ce {->}}\underbrace {\ce {^{234\!m}Pa}} _{\ce {granddaughter~of~^{238}U}}{\ce {->\cdots ->{^{206}Pb ^{\ce {decay~products~of~^{238}U}}}

In this example:

234Th, 234mPa,...,206Pb are the decay products of 238U.

234Th is the daughter of the parent 238U.

234mPa (234 metastable) is the granddaughter of 238U.

These might also be referred to as the daughter products of 238U.[1]

Decay products are important in understanding radioactive decay and the management of radioactive waste.

For elements above lead in atomic number, the decay chain typically ends with an isotope of lead or bismuth. Bismuth itself decays to thallium, but the decay is so slow as to be practically negligible.

In many cases, individual members of the decay chain are as radioactive as the parent, but far smaller in volume/mass. Thus, although uranium is not dangerously radioactive when pure, some pieces of naturally occurring pitchblende are quite dangerous owing to their radium-226 content,[2] which is soluble and not a ceramic like the parent. Similarly, thorium gas mantles are very slightly radioactive when new, but become more radioactive after only a few months of storage as the daughters of 232Th build up.

Although it cannot be predicted whether any given atom of a radioactive substance will decay at any given time, the decay products of a radioactive substance are extremely predictable. Because of this, decay products are important to scientists in many fields who need to know the quantity or type of the parent product. Such studies are done to measure pollution levels (in and around nuclear facilities) and for other matters.

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c

lysosomes contain a variety of enzymes, enabling the cell to break down various biomolecules it engulfs, including peptides, nucleic acids, carbohydrates, and lipids (lysosomal lipase). the enzymes responsible for this hydrolysis require an acidic environment for optimal activity. hope i !
