Mistletoe is a green plant that can make its own food, but also derives food from the mesquite tree on which it lives. In this way mistletoe is able to steal water and valuable minerals from the tree. 1. What is the advantage and disadvantage of this relationship to each organism? 2. What would happen to the mistletoe population if mesquite trees increase in number? 3. What type of symbiosis is this?

Answers

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.

i need help with this can someone help me?

Answers

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.

What is the name of length of time needed for us to pay back our oxygen debt?

Answers

O2 oxygen debt time may vary from individual to individual, but the average is 2 minutes for normal individuals.

What is O2 Oxygen Debt?

Oxygen debt is a physiological phenomenon that occurs when someone consumes oxygen at a faster rate than it can be replaced, leading to an oxygen deficit that causes increased respiration as the body tries to replace used oxygen.

With this information, we can conclude that the time of o2 oxygen debt can vary from individual to individual, but the average is 2 minutes for normal individuals.

Answers

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.

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​

Answers

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.
