How does the molecule marked A enter our body

Answer:

DNA extraction is a routine procedure used to isolate DNA from the nucleus of cells. When an ice-cold alcohol is added to a solution of DNA, the DNA precipitates out of solution. If there is enough DNA in the solution, you will see a stringy white mass.

Explanation:

Predation plays an important role in the overall health of an ecosystem since it regulates the population of preys as well as maintain the population of higher-level consumers. If predators were eliminated from an ecosystem, it would cause an increase of the population of preys and potentially decrease the population of other organisms on lower trophic levels. An example of such effect can be seen from the population of rabbits and plants supposing that foxes, eagles and snakes are eliminated from the ecosystem. The rabbit population will multiply, causing a decrease in the population of plants such as grass that rabbits feed on.

Answer:Publishing results of research projects in peer-reviewed journals enables the scientific and medical community to evaluate the findings themselves. It also provides instructions so that other researchers can repeat the experiment or build on it to verify and confirm the results.

Answer:

1. Mistletoe is parasitic to the mesquite tree, it steals from the tree without giving anything valuable back to it. In this case, only the mistletoe gains an advantage.

2. If the mistletoe population on the tree were to increase, the mistletoe would probably end up slowly killing the tree. I say this because its a parasite to the tree. Its constantly stealing water and valuable minerals that it needs and doesnt give back anything that could help the tree. With all the water and minerals being stolen and an uneven rate with no way for the tree to replenish it all quickly enough it'll die.

3. Its parasitic since the mistletoe just takes and takes harmfully  

Mistletoe plant is a parasite on the mesquite tree as it takes all the valuable minerals and water from the plant and does not give anything valuable in return to the mesquite tree.

Mistletoe plant is a parasite on the mesquite tree, it steals water from the tree without giving anything valuable back to it. In this case, only the mistletoe gains an advantage.

It is a parasite plant since the mistletoe plant just takes all the valuable minerals and water from the tree and thus is harmful.

The reactions of photosynthesis and cellular respiration are interconnected, as the glucose produced by photosynthesis is consumed by animals in cellular respiration.

Cellular respiration is a process of breaking down of food material into simpler forms in releasing energy.

Because oxygen and glucose are produced during photosynthesis from carbon dioxide and water, while water and carbon are produced during cellular respiration, the reactants of photosynthesis and cellular respiration are linked.

The ATP, which is energy transferred as a result of that process, results in the transmission of both water and carbon as byproducts.

Therefore, as the glucose created by sunlight is used by animals during cellular respiration, the reactions of photosynthesis and cellular respiration are interrelated.

Explanation:

Answer: Osmosis occurs when _solvent molecules__ goes from ____lower_____ to ___higher solute concentration______. When the onion and elodea cells were put in salt water the ____water molecules_________ left the cell because their was a ____higher salt concentration________amount outside.

Explanation: Osmosis is simply defined as the net movement of solvent molecules, usually water, from a region of lower solute concentration to a region of higher solute concentration usually through a semi-permeable membrane. Water continues to move out the cell until both solutions in the intra- and extracellular membrane becomes isotonic.

Answer: The nervous system helps all the parts of the body to communicate with each other

Explanation:

Answer:

Explanation:

Osmosis is the spontaneous movement of molecules from low concentration to high concentration. The finger is hypertonic to the swimming pool, which means that it has a higher osmotic pressure. The pool is hypotonic to the finger, which means it has a lower osmotic pressure. Because osmosis goes from low to high concentration, water will seep into the finger, causing it to swell and become wrinkly. This balances out the concentration on both sides of the semipermeable membrane (skin on the finger) and makes them isotonic, meaning they have the same concentration.

Answer: eukaryotic cells

Explanation:

The image shows a eukaryotic plant cell undergoing DNA replication and mitosis to produce daughter cells.

Eukaryotic cells, including plant cells, have a well-defined nucleus enclosed within a membrane, where the genetic material (DNA) is located.

DNA replication is the process of copying the cell's genetic information to ensure each daughter cell receives a complete set of chromosomes.

Mitosis is a form of cell division where the duplicated chromosomes are segregated into two identical daughter cells. This process is essential for growth, tissue repair, and asexual reproduction in plants and other eukaryotic organisms.

The daughter cells will be genetically identical to the parent cell, allowing for the propagation of the same genetic information and traits.
