Answer:

The environmental threat posed by the egregious amounts of plastic waste that have accumulated over the years, and that will likely continue to increase unabated.

The enormous amount of plastic waste that has collected over time and that will probably continue to grow unabatedly poses a hazard to the ecosystem.

A logical argument supported by substantial evidence is a scientific worldview. We need consider what science actually is in order to comprehend why.

Science is a subject that seeks to comprehend the natural world through methodical observation and experimentation.

Because it is a standardized process, the scientific method is significant. Because the steps in the scientific method are methodical, scientists carry out experiments in a predictable way. Thus, such tests may be conducted more widely.

"The Problem with Plastic" suggests that the massive amount of plastic garbage that has accumulated over time and that will likely continue to grow unabatedly poses a threat to the ecology. It is not mentioned in "Make a Change: Alternatives to Plastic Straws."

Thus, this is the meaning of the given quotation.

Answer:

ATP

Explanation:

Adenosine triphosphate, commonly known as ATP, is the chemical molecule that stores and provides/releases energy in cells. ATP is needed by the cells of every living organism and is obtained via a process called CELLULAR RESPIRATION.

Cellular respiration is the process whereby cells breakdown food molecules (sugar) to synthesize energy storing molecules called ATP. Hence, in every tube where cellular respiration is occuring, ATP is the produced molecule that provides energy.

Explanation:

A catalyst refers to any substance that increases the rate of a chemical reaction. A catalyst does not affect the equilibrum position rather it enables the system to attain equilibrum faster.

Biochemical catalysts increase the rate of biochemical reactions in the body. They enable the body to carry out certain important functions that are necessary for life.

Explanation:

Answer: 11. 10% is the concentration of solutes, 12. Osmosis is the net movement of solvent through a membrane according to the concentration of the solution.

Explanation:

Osmosis is a phenomenon that explains the movement of a solvent through a semi-permeable membrane without expenditure of energy, where the movement is through simple diffusion.

The tonicity is the total concentration of all solutes in the solution. Then, when a solution has a few particles, it has a low osmolarity, while a solution with many particles has a hight osmolarity. But, when there are two solutions separated by a permeable membrane to water (and not to the solutes or particles) the solvent (water) will move from the lower osmolarity side to the higher osmolarity side (which means, water moves from a region of low concentration to a region of high concentration)

To compare osmolarity of solutions, we use the terms hypertonic, hypotonic and isotonic. This is done, for example, to compar the osmolarity of a cell with the osmolarity of the extracellular fluid around it.  If the extracellular fluid has a lower concentration than the fluid inside the cell, it is hypotonic with respect to the cell. In this case, the solvent will go into the cell.  If the extracellular fluid has a higher concentration than the fluid inside the cell, it is hypertonic and the solvent will leave the cell from the region of lower solute concentration to the region with more solutes. At last, an isotonic solution is when the extracellular fluid and the cell has the same osmolarity and there will be no net movement of water in or out of the cell.

Increasing on mass would mean that there has been a net movement of water into the bag, because the solution was hypotonic. A decreased on mass mean that there has been a net movement of water out of the bad, because the solution was hypertonic. And if there has been no change or a very little mass change, it means the solution was isotonic, the same osmolarity or concentration of solutes was found inside and outside the cell.

Taking into account the concepts of tonicity and osmolarity, we can explain the process of dialysis which is the process of separating molecules across a semi-permeable membrane in a solution by the difference in their osmotic pressure. It is a laboratory technique where a solution that has many types of different solutes, is put into a semi-permeable sealed dialysis bag, (such as a porous cellulose membrane). Then it is placed in a container with a different solution, or pure water (which has a lower osmolarity). Molecules such as DNA or proteins are larger than the diameter of the pore thereby they are retained within the dialysis bag. However, molecules that are small enough to pass through the pores, such as water, tend to move in or out of the dialysis bag in the direction of the lowest concentration. It is usually used to remove salt from a protein solution.  Then, if a dyalisis tube is labeled as 10%, it means its solute concentration is 10% of to the total volume of the dialysis bag.

Answer:

Please find the diagram of the general structure of amino acids attached.

Explanation:

Proteins are one of the four major biomolecules in living systems. As rightly stated in this question, they are building blocks of the body. However, proteins are biological polymers made up of monomeric units called AMINO ACIDS. A long chain of these amino acids make up a protein molecule.

An amino acid generally consists of a central carbon atom called ALPHA CARBON, attached to an amine group (-NH2), a carboxylic acid group (-COOH), and a side chain (R side chain). All 20 amino acids that exists in nature have this general structure but differs only in the type of SIDE CHAIN (R group) they possess i.e. all amino acids have a different R side chain.

Please find the diagrammatic representation of the general structure of amino acids as an attachment.

Answer:

D. A positive charge, because of a covalent bond with oxygen

Explanation:

A water molecule contain both hydrogen and oxygen atom. Water is a polar molecule because it has positive electric charge in one of it's poles and negative charge on the other. The hydrogen is positively charged and the oxygen is negatively charged which are bonded by covalent bond. Hydrogen is positively charged because it cannot attract electrons strongly like oxygen which is positively charged. There is unequal sharing of electrons in water molecules and this is why oxygen is slightly negative and hydrogen is slightly positive.

The G1Phase

is an intermediate phase occupying the time between the end of cell division in mitosis and the beginning of DNA replication during S phase. Interphase is important before mitosis begins because DNA is duplicated during interphase before the cell undergoes mitosis, the amount of DNA in the original parent cell and the daughter cells are exactly the same.

Explanation:

Simple answer:

When corals are stressed by changes in conditions such as temperature, light, or nutrients, they expel the symbiotic algae living in their tissues, causing them to turn completely white. Warmer water temperatures can result in coral bleaching. ... This is called coral bleaching. When a coral bleaches, it is not dead.

More in depth explanation:

Exposure to higher (100 and 1000 µg l-1) diuron concentrations for 96 h caused a reduction in ΔF/Fm¹, the ratio variable to maximal fluorescence (Fv/Fm), a significant loss of symbiotic dinoflagellates and pronounced tissue retraction, causing the corals to pale or bleach.

Answer:

''By doing hard activity, the pumps very fast.''

Explanation:

''By doing hard activity, the heart pumps very fast.'' is my hypothesis. In this hypothesis, I mentioned that during hard activity pumping of heart goes very fast because our body needs oxygen as well as energy in the form of ATP and the only way to get both oxygen and energy is the pumping of heart which supply oxygen to the cell as a result energy is generated in the form of ATP and removes carbondioxide gas by breathing.
