Answer:
The banana is a perennial plant that replaces itself. Bananas do not grow from a seed but from a bulb or rhizome, and it takes 9 to 12 months from sowing a banana bulb to harvesting the fruit. The plants need rich, dark and fertile soils with steady moisture in the air and ground and good drainage.
Calcium are needed to ensure rotten root, leaf development, thereby providing high yields. Its effects are most important in ensuring high quality fruit with long term storage potential. Magnesium have a direct effect on yield, increasing the number and weight of fruit per banana bunch.

Which statement best describes the difference between a substance with a pH of 3.0 and a substance with a pH of 6.0? (1 point)
O The substance with the higher pH has twice as many hydrogen ions per volume of water.
The substance with the lower pH has twice as many hydrogen ions per volume of water.
The substance with the higher pH has 1,000 times as many hydrogen ions per volume of water. O
O The substance with the lower pH has 1,000 times as many hydrogen ions per volume of water.
Answer: c
Explanation: 3.0 is 1,000 times as many ions
The statement that best describes the difference is ; The substance with the lower pH has 1000 times as many hydrogen ions per volume of water. ( D )
Given that the substance have pH ; 3 and 6
To prove the statement above we will make use of the pH formula
pH = -log(H⁺)
for substance with pH = 3
3 = - log(H⁺)
H⁺ ( hydrogen ions ) = 10⁻³
for substance with pH = 6
6 = - log(H⁺)
H⁺ ( hydrogen ions ) = 10⁻⁶
Hence we can state that the substance with the lower pH has 1000 times as many hydrogen ions per volume of water

4. What conclusions will John be able to make from the results of the experiment?
The answers to the questions required for the design experiment above are :
If shark attack are related to the number of elephant seals in an area, then shark attack will increase as the number of elephant seal increases If shark attack are unrelated to number of elephant seal in an area, then shark attack is unaffected by increase or decrease in number of elephant seal. The Control Group : Beaches or areas where elephant seals aren't present or period of the year when there are no elephant seal at the beach. The Experimental group : Beaches where varibale portions of elephant seals are found (area with high, medium or low). The Dependent variable : Number of shark attacks The Independent variable : The different number of elephant seals found. Data to be collected include : The number and type of elephant seals found at various beaches and the number of shark attacks recorded at the various points. John will be able to deduce if the number of elephant seals and number of shark attacks recorded corded are related.The hypothesis of an experiment is a proposition which requires experimental testing in other to establish it's validity.
The Control Group refers to a portion of the subject which aren't given or exposed to the treatment used in an experiment.
The Experimental group are the portion of the subjects which are subjected to the treatment condition.

Which fuel does the circulation of blood provide for cellular respiration and healing?
A. oxygen
B. protein
C. iron
D. ATP
Answer:
A. Oxygen
Explanation:
During cellular respiration the cell uses oxygen to break down sugar. When sugar breaks down it produces energy in which your body needs. Blood picks up oxygen and releses carbon dioxide into your lungs.
Hope this helps!!
The fuel responsible for the circulation of blood is oxygen.
It is very important for blood circulation to occur in the body. This is very essential so that all the cells and organisms are sufficiently funded with enough oxygen that is needed for them to function properly.
The fuel which enables proper amount of blood to spread/circulate round the body is oxygen. Oxygen is required during cellular respiration to break down sugar which then leads to the production of carbon dioxide and then releases energy for the body to work well.

how do i find out the eyepiece magnification?
Answer:To calculate the magnification, we just need two numbers:
The telescope’s focal length (for example, 1200mm)
The eyepiece’s focal length (for example, 25mm)
Explanation:
explain why oxygen and glucose need to be absorbed and waste products need to be removed
Explanation:
Oxygen and nutrients from food must be absorbed into the bloodstream to be delivered to cells for respiration. Waste materials such as carbon dioxide must be removed from cells into the bloodstream. Tissues contain capillary networks to allow these exchanges to occur at a cellular level.
Oxygen and glucose needs to be absorbed and waste products need to be removed for the proper functioning and maintenance of the body cells and systems.
Oxygen is an odor less and colourless gas that is needed by living organisms.
It is absorbed by living organisms because it serves as a source of fuel.
Glucose is a type of carbohydrate called monosaccharide which is gotten from food.
It is assimilated or absorbed into the body through the hormone insulin and serves as a source of energy.
Waste products of metabolism is removed from the body through the process of excretion. A typical example is the carbondioxide.
If Waste products are allowed to accumulate they cause poisoning which slows down vital chemical reactions.

Light that Moves and Molds Gels
Pitt research team demonstrates gels that can be moved, controlled by light
PITTSBURGH—Some animals—like the octopus and cuttlefish—transform their shape based on environment, fending off attackers or threats in the wild. For decades, researchers have worked toward mimicking similar biological responses in non-living organisms, as it would have significant implications in the medical arena.
Now, researchers at the University of Pittsburgh have demonstrated such a biomimetic response using hydrogels—a material that constitutes most contact lenses and microfluidic or fluid-controlled technologies. Their study, published in Advanced Functional Materials, is the first to show that these gels can be both reconfigured and controlled by light, undergoing self-sustained motion—a uniquely biomimetic behavior.
Together with Olga Kuksenok, research associate professor in the Swanson School, Balazs experimented with a newer type of hydrogel containing spirobenzopyran molecules. Such materials had been previously shown to form distinct 2-D patterns on initially flat surfaces when introduced to varying displays of light and are hydrophilic in the dark but become hydrophobic under blue light illumination. Therefore, Balazs and Kuksenok anticipated that light could be a useful stimulus for tailoring the gel’s shape.
Using computer modeling, the Pitt team demonstrated that the gels “ran away” when exposed to the light, exhibiting direct, sustained motion. The team also factored in heat—combining the light and local variations in temperature to further control the samples’ motions. Controlling a material with light and temperature could be applicable, Balazs said, in terms of regulating the movement of a microscopic “conveyor belt” or “elevator” in a microfluidic device.

“Imagine an apartment with a particular arrangement of rooms all in one location,” said lead author Anna Balazs, Pitt Distinguished Professor of Chemical and Petroleum Engineering in the Swanson School of Engineering. “Now, consider the possibility of being able to shine a particular configuration of lights on this structure and thereby completely changing not only the entire layout, but also the location of the apartment. This is what we’ve demonstrated with hydrogels.”

velocity?
Answer:
Given,
initial velocity= 25m/s
acceleration= 5 m/s
time= 3 s
final velocity= ?
We know that,
acceleration= final velocity- initial velocity/ time
or, 5 = final velocity- 25 / 3
or, 5*3 = final velocity- 25
or, 15+ 25= final velocity
Therefore, final velocity is 40 m/s.

How would the loss of predators contribute to deforestation in the
jungle?
Answer:
Predators eat prey. When they do so, they are keeping the population or number of prey in check. Now, a lot of prey are either herbivores or omnivore, meaning plants are in their diet. If there were to be no predators, an absurd overpopulation of prey would arise. This would cripple the growth of young trees by the prey feeding on them, and overall would over-run their habitat, making the food sources scarce. When the food source gets so low they will die out or continue to move on to other surrounding areas and create the same problems.
