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.

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.

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.

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.

Invasive species
Exotic species
Endemic species
Indigenous species
Answer:
The correct answer is - Indigenous species.
Explanation:
Indignous species are the species that are not introduced in a region by human interferance or accident and home based or present by the natural processes.
It is equivalent to the native species but not the same as they come from different region by the any natural phenomenon and can effect the ecosytem negatively. Beach morning glory is native plant to the Polynesian island but is an indigenous plant and cover all over the rail road.

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.
