Answer:
Plants get the carbon dioxide they need from the air through their leaves. It moves by diffusion through small holes in the underside of the leaf called stomata. These let carbon dioxide reach the other cells in the leaf, and also let the oxygen produced in photosynthesis leave the leaf easily.
Answer:
small holes on underside

True or false - mutualism can be described as a 'win-win' situation.
Answer:
true
Explanation:
In nature, when two individuals of different species often live in close association with each other, this leads to a phenomenon called symbiosis. ... Mutualism is a win-win situation for both organisms because both benefit from the relationship. With commensalism, one organism benefits while the other is unaffected.

What makes DNA Replication possible?
Answer:
The amount of cells in the body and the genes from each parent.
Explanation:
Answer:
The initiation of DNA replication occurs in two steps. First, a so-called initiator protein unwinds a short stretch of the DNA double helix. Then, a protein known as helicase attaches to and breaks apart the hydrogen bonds between the bases on the DNA strands, thereby pulling apart the two strands.
Explanation:
An airplane flies with a constant speed of 600 km/h. how far can it travel in 4 hours?
Answer: 2,400 kilometers.
Explanation: If an airplane flies at a constant speed of 600 km/h, then it travels 600km in one hour. Therefore, in four hours (600km*4), it will travel 2,400.

A skeletal muscle is a composition of several components bundled one into the other. At which structural level in the muscle does contraction
occur to bring about contraction in the whole muscle?
OA myofibril
OB. muscle fiber
Oc myoneural Junction
OD tendon
OE. fascicle
Answer:
myofibrils
Explanation:
The skeletal muscles are involved in the movement and actions. The myofibril initiates the contraction to make the whole muscle contract. Thus, option A is correct.
What is myofibril?Myofibril is an organelle of the muscle cells that makes the muscle fibers of the skeletal muscles. The myofibril comprises myofilaments that are responsible for appearance and movement.
The myosin is the thick myofilament and actin is the thin myofilament that comprises the sarcomere that brings about the contraction by sliding over each other.
Therefore, the myofilaments (actin and myosin) of myofibril bring about the contraction of the muscles.

How are photosynthesis and cellular repiration similar
Answer: The two processes are similar in that they both produce energy, albeit in two different forms. They are different in that photosynthesis assembles the glucose molecule, while cellular respiration takes it apart.
Explanation: Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.

PLZ HELP ASAP! No copy and pasting!
Fusarium oxysporum is a fungus that attacks tomato plants, causing them to wilt and die. The fungus initially blocks the xylem and grows extensively within parenchyma. As the plant continues to wilt, the blockage of both xylem and phloem can be observed. The result is the suppression of both the xylem sap circulation in the plant and photosynthetic activity in the leaves.
Based on these observations, explain how the fungus affects the role of both the xylem and the phloem.
Answer:
The xylem transports water to the plant, so if the fungus blocks the xylem, the plant would eventually dehydrate, affecting the role of the xylem.
The phloem transports glucose, nutrients and such, therefore the fungi may try to steal the nutrients for the plant, affecting its role.
