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.
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.
What is Mistletoe plant?
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.
If the mistletoe population were to increase on the tree, the mistletoe plant would probably end up killing the mesquite tree. This is because it is a parasite to the tree. It is constantly stealing water and valuable minerals from the tree which it needs and doesn't give back anything valuable that could help the tree.
It is a parasite plant since the mistletoe plant just takes all the valuable minerals and water from the tree and thus is harmful.

Is it possible for a blood type B parent and a blood type A parent to have a blood type O child?
A. Yes
B. No
Answer:
yes
Explanation:
you have your own chromosomes so that's how
Answer:
no
Explanation:
B blood type. But someone who has a B and an O version only makes the B protein. They are B blood type but can pass the O onto their kids. So two B parents can make an O child if both parents are BO.

A. She is observing a gnetophyte because, unlike other gymnosperms, gnetophytes can grow as shrubs in deserts.
B. She is observing a gnetophyte because, unlike other gymnosperms, gnetophytes can have needle-like leaves and deep root systems.
C. She is observing a ginkgo because, unlike other gymnosperms, ginkgoes can grow as shrubs in deserts.
D. She is observing a ginkgo because, unlike other gymnosperms, ginkgoes can have needle-like leaves and deep root systems.
Answer:The answer is B
Explanation:I took the test
The scientist is observing a gnetophyte because unlike other gymnosperms, gnetophyte can have needle-like leaves and deep root systems.
What are gymnosperm?'Gymnos' means 'n aked' and 's perm' means 'seed'.It reproduces by means of an exposed seed or ovule.They do not produce fruits and flowers.What are gnetophyte?They belongs to gymnosperm.Their leaves become needle-like to reduce transpiration.They are vascular plants.The reproductive structure are contained within cones.Hence, the correct option is B. She is observing a gnetophyte because, unlike other gymnosperms, gnetophytes can have needle-like leaves and deep root systems.

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.
