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
Answers
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.

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.
Answers
The phloem transports glucose, nutrients and such, therefore the fungi may try to steal the nutrients for the plant, affecting its role.
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.

Answers
Answer:
compost
Explanation:
Among the choices mentioned above, it is only "compost" that is biological in origin. That's because it came from organic waste products that were decomposed; thus the name "compost."
Compost consists of essential nutrients (phosphorus, nitrogen and potassium) ideal for fertilizing the soil. This is often added to the soil and used in gardening and farming. It also aids in plant's immunity by resisting plant diseases.

These organelles are the site of photosynthesis. They contain green pigment known as chlorophyll which can capture sunlight. The light energy plus carbon dioxide and water are converted into glucose and oxygen.

What is the effect of catalase on the decomposition of hydrogen peroxide? A. It decreases the activation energy needed to start the reaction. B. It decreases the total energy released by the reaction. C. It increases the total energy absorbed by the reaction. D. It changes the ratio of the amounts of the two products.
Answers
Answer:
A. It decreases the activation energy needed to start the reaction.
Explanation:
Catalase is an enzyme found in the cells of organisms exposed to aerobic conditions. It is an enzyme that catalyses the breakdown or decomposition of hydrogen peroxide in the liver to water (H2O) and oxygen (O2).
Catalase, like every other enzyme, operates by binding to the substrate, which in this case is hydrogen peroxide. Catalase then REDUCES or LOWERS the ACTIVATION ENERGY needed to start the reaction.
True or false - mutualism can be described as a 'win-win' situation.
Answers
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.

Bromothymol blue (BTB) is a pH indicator that is also used to detect carbon dioxide (CO2). BTB is blue when pH is basic and CO2 is low. BTB is yellow when pH is acidic and CO2 is high. BTB is green when pH is neutral. A group of students are planning to perform an investigation in which they will place either a stalk of the aquatic plant elodea or a snail in a test tube that contains water with a neutral pH of 7 and BTB. The students will also include a test tube that contains elodea and a snail. Observing color change once the tubes have been placed under a growth light for several hours will allow the students to answer which TWO of the following questions?
A. Do both elodea and snails require oxygen to survive?
B. Does elodea produce oxygen during photosynthesis?
C. Do snails respire faster when placed in a tube with elodea?
D. Do snails use the CO2 produced by elodea to produce oxygen?
E. Does photosynthesis performed by elodea remove CO2 from the water?
F. Does cellular respiration occur at a higher rate than photosynthesis in the tube with only elodea?
I need 2 answers! Thanks
Answers
Answer:
E. Does photosynthesis performed by elodea remove CO2 from the water? F. Does cellular respiration occur at a higher rate than photosynthesis in the tube with only elodea?Explanation:
The tubes were placed under a growth light and as the elodea is growing, it would need photosynthesis to provide food. The color changes will therefore allow the students to see the effect photosynthesis has on the CO2 in the water by checking to see if the BTB turns blue which would mean that CO2 was removed by photosynthesis.
The students will also be able to see which process occurs faster in the tube with only elodea because the dominant color would show if cellular respiration occurs faster than photosynthesis or if the case is the reverse. For instance, if respiration is occurring faster, there will be more CO2 which would turn the BTB towards yellow, if photosynthesis is faster the BTB will turn towards blue and if the rates are similar, the BTB will remain green.
How are photosynthesis and cellular repiration similar
Answers
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.
