a human red blood cell is placed in a solution whose solute concentration is twice as great as the concentration of the cell cytoplasm. The cell membrane is selectively permeable allowing water but not the solutes to pass through. What will happen to the cell? a.) No change b.) the cell will shrivel because of osmosis c.) the cell will swell because of osmosis d.) the cell will shrivel because of active transport of water e.) the cell will swell because of active transport of water
Answer:
the cell will shrivel because of osmosis, moving to the region of higher concentration, and it shrivels due lost of water
explain how a molecule of carbon dioxide from the atmosphere teaches the site of photosynthesis in a leaf
Answer: On the surface of the leaves of the plants there are a large number of tiny pores known as stomata or stoma. For photosynthesis green plants take carbon dioxide from the air. The carbon dioxide enters the leaves of the plant through the stomata present on their surface. Each stomatal pore is surrounded by a pair of guard cells.

Explain how water move from cell to cell in a leaf
Answer:
By osmosis, water enters the root and travels through the root cells until it reaches the xylem vessels. These canals carry water from the stem to the leaf. Transpiration is the process of removing water from the leaves of plants via evaporation.
Explanation:
Water moves from cell to cell in a leaf through a process called transpiration, facilitated by a combination of cohesion, adhesion, and capillary action in the plant's vascular system.
Transpiration: Transpiration is the process by which water vapor exits the leaf's stomata (tiny openings on the leaf surface) into the surrounding atmosphere. As water vapor evaporates from the cells within the leaf, it creates a lower pressure within the leaf's interior, drawing water molecules from neighboring cells.
Cohesion refers to the attraction between water molecules, causing them to stick together. Adhesion, on the other hand, is the attraction between water molecules and the surfaces of other materials, such as the walls of plant cells and the walls of xylem vessels. These properties work together to create a continuous column of water within the plant's vascular system, allowing water to move upward from the roots to the leaves.

why would one gene work as a barcode for one species and not for another
One gene work as a barcode for one species and not for another because for different species different barcodes are used.
Every specie is different than another organism genetically so it also needs different barcodes for every other specie. If all the species are made up of the same gene then we can say that one barcode is used for all of them but its not the case.
Every organism has different and its own gene so one gene barcode is not acceptable for all species but for the original one so we can conclude that one barcode is used for one species and not for another.

this is true believe meillustrate how the self sealing bubble membrane helps to illustrate the passage of molecules through a cell membrane and the property of selective permeability
Self-sealing bubble membranes help to illustrate the passage of molecules and the property of selective permeability in that they are an example of how something can be semi-permeable and allow only some substances to pass.
When we mention a membrane, we refer to the selective barrier that protects cells from the environment. Within this barrier, lie certain proteins that serve as a kind of "tunnel" for the passage of very specific substances. This, along with a few other mechanisms are what gives a membrane the title of being semi-permeable.
This is because semi or selective permeability is the ability to allow the passage of very specific substances despite being a sealed barrier. Self-sealing bubble membranes share this ability by allowing some substances, like specific gases, to enter the bubble while others will remain on the exterior of the sealed barrier.

Explanation:
HOPE IT HELPS...............Cetaceans (whales, dolphins, and porpoises) are all Mammals. Whales usually are larger and slower in the water. Porpoises normally do not have a pronounced beak as a dolphin would. Dolphins have a curved dorsal fin. Dolphins and Porpoises are extremely intelligent. They are warm-blooded. All dolphins are whales, but not all whales are dolphins. Different animals live in different areas. Killer whales are adapted to colder areas, and they stay in the colder water. Bottlenose dolphins are best suited for warmer areas such as the Atlantic Ocean, so they will have less body fat or flubber because they live in a warmer climate. The Killer Whale will need more body fat because of the colder temperatures. They have smooth bodies to help them swim. They have tiny hairs, but as they age, the hair disappears. They can stay underwater longer based on their breathing and extract oxygen from water; they make super high pitch noises that Bounce off objects in the water Back towards the Dolphins to help determine the location; this is called Echolocation.
