Explain how water move from cell to cell in a leaf

Answers

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.

H-E-L-P! ASAP! Describe two ways that plants respond to their environment, giving an example of each. Your answer can include ways that plants respond to seasonal changes, light, gravity, or touch.

Answers

Plants have evolved to respond to critical changes in the environment by either growing their roots, or leaves towards/away from any stimulus. This response, is called a tropism.

For example, The plant's stem and leaves bend toward sunlight. Their roots grow toward Earth's gravity.

Plants have complicated systems to detect and then respond to changes in light, gravity, temperature, and or even physical touch.

Answers

The receptors that aid in allowing a person to maintain balance are located within the inner ear.

The human ability to walk upright without falling, and a wide variety of other tasks that we perform as all thanks to our ability to maintain balance. This ability is given to us by structures located deep within the inner ear.

The inner ear is located deep within the lateral side of the head. This ear contains 3 semicircular canals or ducts, which are tiny structures filled with liquid. Each of these canals has an expansion at its end known as the ampulla, which holds within it the very small cellular balance receptors called crista.

Community ecology!

Explanation:

I’m just did this assignment and got it right <3

A study is conducted to evaluate the effect of competition between foxes and coyotes for a limited food source. The level of ecology being studied is community ecology. The correct option is d.

What is community ecology?

The ecosystem is the fundamental unit for maintaining life, although it extends beyond species living in a single location. The recycling of resources between organisms and their environments, between organic and inorganic forms, is essential to life.

Community ecology is the study of the structure and function of communities, which are assemblages of interacting populations of species living in a certain area or habitat.

A community in ecology is a group or association of populations of two or more different species that live in the same geographical area and at the same time, also known as a biogenesis.

Therefore, the correct option is d, community ecology.

Answers

Answer:

B) Mushroom --> Heterotroph

C) Algae --> Autotroph

A) Autotroph --> Producer

D) Hetrotroph --> Comsumer

Explanation:

Mushrooms are decomposers because like other fungi, they break down dead and decaying matter to make their own food

Producers, such as plants and algae, acquire nutrients from inorganic sources that are supplied primarily by decomposers whereas decomposers, mostly fungi and bacteria, acquire carbon from organic sources that are supplied primarily by producers.

Primary producer; organisms, such as plants and phytoplankton, that can produce their own food through photosynthesis or chemosynthesis; also called autotrophs.

Consumers are also referred to as heterotrophs in contrast to autotrophs, which are the producers of the food chain. Consumers therefore include animals and heterotrophic bacteria and fungi. Plants that are carnivorous and therefore consume organic matter as well are regarded as both consumers and producers.

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

Answers

Answer:

the cell will shrivel because of osmosis, moving to the region of higher concentration, and it shrivels due lost of water

B is the correct thing. The water molecules with the cell with move to hypertonic solution until an equilibrium is reach . But in this case solute concentration is twice that of the red blood cell therefore the protoplasm of the red blood cell will move further away from cell. Hence the process called crenation (shrivel )

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.
