Why do cells continue to divide in adult organisms?

Answers

Although most of the tissues in adult organisms maintain a constant size, the cells that make up these tissues are constantly turning over. Therefore, in order for a particular tissue to stay the same size, its rates of cell death and cell division must remain in balance.

Answer:

Although most of the tissues in adult organisms maintain a constant size, the cells that make up these tissues are constantly turning over. Therefore, in order for a particular tissue to stay the same size, its rates of cell death and cell division must remain in balance.

Explanation:

There are two main reasons why cells divide rather than continuing to grow larger and larger: The larger a cell becomes the more demands the cell places on its DNA. If the cell grows too large, it will have trouble moving enough nutrients and wastes across the cell membrane. Why does cell division remain important to an adult organism even after it is fully developed? It remains important because cells are renewed and wounds are healed in the process. When cells stop dividing to specialize in structure and function. When cells undergo programmed cell death.

In the biosphere, _________________ is an important element in ATP (Adenosine triphosphate) and DNA (Deoxyribonucleic acid).

A. Phosphorus
B. Phosphate
C. Photosynthesis
D. Photons

Answers

C would be your answer

In the biosphere, phosphorus is an important element in ATP (Adenosine triphosphate) and DNA (Deoxyribonucleic Acid), which is in Option A, as phosphorus is a crucial element in the biosphere as it is a component of both ATP (Adenosine triphosphate) and DNA (Deoxyribonucleic Acid).

What is phosphorus?

Phosphorus is essential for the formation of the backbone of the DNA molecule, where it links the sugar and nitrogenous base components of the nucleotides. The phosphate group of each nucleotide forms a covalent bond with the sugar molecule of the adjacent nucleotide, forming a long, stable chain of nucleotides that make up the DNA molecule. The DNA molecule is responsible for transmitting genetic information from parent to offspring and serves as a blueprint for the development and function of living organisms.

Hence, in the biosphere, phosphorus is an important element in ATP (adenosine triphosphate) and DNA (deoxyribonucleic acid), which are in Option A.

What are the potential advantages and disadvantages of a major shift from the hard or traditional path of energy development to the soft or visionary path?


(These were the corresponding textbook pages, if needed) Please read the following from the textbook Environmental Science:

7th Edition - Chapter 17

9th Edition - Chapter 14

Answers

It’s terms in the set 10

Answer:

Advantages of following the soft path, the argument here is alternative sources of power such as hydropower, geothermal energy , wind energy , and photovoltaic cells must be developed. This provides a alternative source to remain in a healthy environment and also function as the society we currently live in using the hard path.  Disadvantages of following the hard path result with future generations fearing over the irreversible damage of climate change and the damage done to our atmosphere. The hard path argue that we should continue to operate in the future as we have in the past, except more efficiently. This is close to impossible and will only continue the negative effects the hard path( the path we have been following) results in. The major shift determines the outcome of this world, the futures worries or reliefs and ultimately the survival of humans.

The fishery can operate at one of two locations: upstream (above the mill) or downstream (in the polluted part of the river).

The mill earns $500 in profit, and the technology exists for it to build a treatment plant at the site that completely eliminates the pollution, but at a cost of $200.
