Answer:the answer is b
Explanation:
The answer is b because run of river cannot serve a lot of purposes like the storage dam and the dam is like most sturdier than the run of river.
When it comes to run-of-the-river-dams and storage dams, а. Run of the river dams are less damaging to the environment.
What is a run-of-the-river dam?This is a type of dam that allows for the natural flow of water to continue without attempting to store the water.
As a result, it is not as damaging to the environment unlike storage dams which store water and disrupt flow and migration patterns.

How does the hydrogen concentration of a solution change when the pH shifts from 6 to 2? (4 points)
Answers
Answer:
the overall concentration of hydrogen ions is universely related to its PH and can be measured on the physical (figure 1). therefore, the more hydrogen ions present.
The hydrogen ion concentration of a solution increases when pH shifts from 6 to 2.
What is pH?a metric for determining how basic or acidic a substance or solution is. The pH scale ranges from 0 to 14. A pH value of 7 is considered neutral on this scale, meaning it is neither acidic nor basic. It is more acidic if the pH value is below 7, and more basic if the pH value is above 7.
Typically, a pH meter is used to measure pH, which converts the difference in electromotive force (electrical potential or voltage) between suitable electrodes put in the solution under test into pH measurements.
The different solutions have different pH based on the concentration of hydrogen ions. The concentration of hydrogen ions increases when pH shifts from 6 to 2.

Cell organelles are mitochondria, ribosomes, vaccuoles, cell wall, endoplasmic reticulum, nucleus and many more.
In the cytoplasm, tRNA, play major role in protein synthesis and tRNA brings amino acids to the ribosome according to the codon in the mRNA which is translating. tRNA contain anti-codon which recognize and bind to the codon as by base pairing where they are linked to protein synthesis as well as tRNA is loaded by aminoacyl-tRNA synthetase enzyme with correct amino acid, which they bring to ribosome for protein synthesis.

enzymes are not consumed in a reaction. they remain mixed with reactants. if all products have reacted in the reaction and there's nothing left, the answer is products.

why does cell division occur in sexually reproducing organisms?
Answers
Answer:
to produce a complex multicellular individual
Explanation:
hope this helps
Cell division occurs in sexually reproducing organisms to maintain the organisms growth and development. Cells have a particular life cycle after which they die. These cells need to be replaced constantly.
What is Cell division?Cell division is the fundamental process to all living organisms and required for the growth and development of organisms. It is an essential means of reproduction for all the living things, cell division allows organisms to maintain their number and to transfer their genetic material to their offspring.
The role of this process in sexual reproduction is to produce sex cells (gametes) and to repair the genetic defects in germ line cells (sex cells). Both sexual and asexual organisms go through the process of mitosis. However, sexual reproduction also includes meiosis which maintains the number of chromosomes in off-springs.

approximately how many nucleosomes are required to organize this region of dna into the 10nm fiber structure?
Answers
Answer:
Answer is 512 nucleosomes.
Explanation:
DNA is the genetic material that is compressed and stored in the nucleus of the cell. Approximately 512 nucleosomes would be required to organize 92,672 base pairs long region.
What are nucleosomes?Nucleosomes are the packaging units of the genetic material that comprises the DNA segments wrapped along with the histone proteins in a compacted manner. This allows the genetic material to be condensed into smaller volumes.
Given,
Genome size = 92,672 base pairs
Linker DNA = 35 bp
The total number of base pairs = number of base pairs in nucleosome core + linker DNA
= 146 + 35
= 181
The number of nucleosomes can be calculated as:
Nucleosomes = Genome size ÷ total number of base pair
= 92,672 ÷ 181
= 512
Therefore, there are 512 nucleosomes are present in the Drosophila.

Plastic wrap is commonly made out of PVC (Polyvinylidene Chloride). In recent years other PVC alternatives have become more popular. The most popular option in recent years is LDPE (Low-Density Polyethylene) because it is considered to be safer for the body. The best management for plastic wrap would have to be by you taking plastic wrap to local retail stores where they collect plastic grocery bags for recycling. Any package that you see with the How2Recycle Store Drop-Off label can be recycled this way.
Human waste from excretion is probably classified as organic waste, since it comes from you and the food you eat. The best management for human excretion would probably be sewer pipes that lead into the sewage system that lead into other mainframes.
Wastewater is an odd typing since it contains human waste, food scraps, oils, soaps and chemicals. The best management for this would include physical water treatment, biological water treatment, chemical treatment, and sludge treatment.
Con đường vận chuyển nước vậy ông chất khoáng qua thành tế bào sang bào ở thực vật có đặc điểm gì
Answers
Answer:
In plants, minerals and water are transported through the xylem cells from the soil to the leaves. The xylem cells of the stem, roots, and leaves are interconnected forming a conducting channel reaching all plant parts. Thus, there is continuous water movement into the xylem.
Bài giải:
Ở thực vật, các chất khoáng và nước được vận chuyển qua các tế bào xylem từ đất đến lá. Các tế bào xylem của thân, rễ và lá liên kết với nhau tạo thành một kênh dẫn đến tất cả các bộ phận của cây. Do đó, có sự chuyển động liên tục của nước vào xylem.
