What is the relationship between mutation, natural selection, and adaptation?
Explanation:
well a mutation in my opinion is genetic change that happened in the animal this could be beneficial or may not be. natural selection is a process that ensures only the best of the species survives and more of them will produce because all of the flawed ones will die off. adaptaion is when a plant or animal adapts to its surrounding over time they may develop a charterisric that will help them thrive. all of them tie togethor

What do scientists need to extract the DNA from? How much DNA is there?
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.

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

only the recessive trait is visible.
neither the dominant nor recessive trait is visible.
both the dominant and recessive traits are visible.
Answer:
a on edgen
Explanation:
only the dominant trait is visible
In the Fi generation of a Mendelian cross, only dominant traits.
What is the Mendelian cross?It is the genetic cross. The Mendelian cross was developed by Mendel. It explains the inheritance patterns in the organism and plants. The experiment which leads to the development of the Mendelian crosses was on sweet peas. Examples of Mendelian crosses are, all the breeds were true generations.
When the true breeding of violet flower color with the true breed of white flowers which is also known as the P generation are crossed. This results in the generation of hybrid violet color flowers which is also known as the F1 generation. The types of Mendelian cross are monohybrid, dihybrid, test cross, and back cross. The uses are genotype and phenotype of progeny.

Osmosis occurs when ____________ goes from _________ to _________. When the onion and elodea cells were put in salt water the _____________ left the cell because their was a ____________amount outside.
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.
What is the sentence of pluripotent?
After swimming in the pool for 2 hours, your friend starts to complain because his fingers and toes are wrinkled. Use the concept of osmosis to explain why. Be sure to include the following in your explanation: The terms hypotonic, isotonic, and/or hypertonic (as well as what they mean) • The overall direction of water movement and reason why • How the movement of water causes his fingers and toes to change • A picture if necessary
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.
i need help with this can someone help me?
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.
