Answer:
A homogenous solution is uniform throughout. Meaning that it has the same composition/looks the same through out the solution. It can be called a homogenous solution or mixture. The other type of solution is a heterogenous solution. This solution is is visibly different looking, so it does not look the exact same throughout.
eg:
Milk is an example of a homogenous solution. It looks the same all throughout but when you look at it under a microscope you can then see it is actually consisted of different things.
Sand in a cup of water is a heterogenous solution. You are able to visibly see the different compounds that make up the solution.

When considering the semi-conservative model of DNA replication, how many of the
resulting DNA molecules would have a piece of the original DNA molecule after two replication events?
A. 1
B. 2
C. 3
D. 4
URGENT PLEASE HELP
Answer:
I think B is right answer
When considering the semi-conservative model of DNA replication,2 of the resulting DNA molecules would have a piece of the original DNA molecule after two replication events. Thus option B is correct.
what is semiconservative nature of DNA ?The semiconservative nature of DNA means where the nitrogenous bases of the “parent” strand act as a template for the synthesis of new DNA strands in the cell.
The DNA has two helices where one strand is parent DNA strand of the DNA helix while the other strand of DNA is the newly synthesized one where all the genetic information is copied from the template strand.
During DNA replication the DNA molecule is broken and separated into two single DNA strands, each of the strand is duplicated to create two new double helix strands, which preserve one strand from the parent sample in each replication.
Therefore, due to the duplication the strand of DNA have one of the original parent strands, by the process is semiconservative DNA replication.

What type of cell is shown the image?
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.

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

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?
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.

Explanation:
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.

The net primary production of a pine forest on a lava flow on Mount Fuji is about 165,000 kcal/m2/yr, and the plant respiration is estimated to be 95,000 kcal/m2/yr. What is the total amount of energy transferred during photosynthesis for this ecosystem?
Answer:
The total amount of energy transferred during photosynthesis for this ecosystem equals 260,000 kcal/m2/yr.
Explanation:
To answer this question, we need to know that
gross primary productivity (GPP) = energy captured and converted into chemical energy during photosynthesisnet primary productivity (NPP) = difference between GPP and respiration rateSo, to calculate GPP we need to sum NPP to Respiration rate. This if,
NPP = 165,000 kcal/m2/yr
R = 95,000 kcal/m2/yr
NPP = GPP – Respiration
Then,
GPP = NPP + R
GPP = 165,000 kcal/m2/yr + 95,000 kcal/m2/yr
GPP = 260,000 kcal/m2/yr
