Answer:
1)•Plants do not have a circulatory system.
•Humans have a well defined circulatory system.
2)•transportation in plants occurs through specialised tissue xylem and phloem.
•Transportation in humans occurs through a netwotk of blood vessels such as artery vein capillary.
3)In plants substances transported are water, minerals, sugars and amino acid.
•In humans substances transported are glucose, glycerol, minerals, vitamins, fatty acids, amino acids and hormones.
4)Transportation in plants in controlled by opening and closing of stomata.
•Transportation in humans is controlled by constriction or dilation of blood bessels.
-->■Transportation in humans is more effective than the plants because in humans there is a well defined circulatory system which is highly regulated.As transport occur through blood vessel , transportation can be regulated by dilation or constriction of blood vessel.But plant do not have such circulatory system.

What is needed for natural selection to occur? select all that apply.
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.

Particulate matter released during manufacturing that does not change form in the atmosphere is considered to be
primary pollutants from a stationary source
primary pollutants from a mobile source
secondary pollutants from a stationary source
secondary pollutants from a mobile source
Answer:
I think A, "Primary pollutants from a stationary source"
Explanation:
Got it right on exam :)
Particulate matter is defined as material emitted during manufacturing that does not change form in the atmosphere and is a primary pollutant from a stationary source. The correct option is a.
What is particulate matter?One of the least evident types of pollution is particulate particles. NOT the case for pollution from particle matter. Particle pollution, commonly known as particulate matter (PM), is a type of air pollution made up of microscopic fragments of solids or liquids.
Dust is one possible type of these specks. Dirt. Soot. Particulate pollution can exacerbate acid rain while also altering weather patterns, causing drought, accelerating global warming, and causing the ocean to become more acidic.
Therefore, the correct option is a. primary pollutants from a stationary source.

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.

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 foodProducers, 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.Have a great day! :D

illustrate 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.

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.
