Answer:
Frequency is inversely proportional to wavelength.
Explanation:
frequency is the number of oscillations in a unit of time.
Wavelength is the length between one oscillation and the next oscillation.
take two springs and 4 pins. (springs should have loops or hooks at terminals to attach to pins.)
Now get two pins and pin them at a certain distance apart.
take the first spring and attach its two terminals to the pins.
Repeat the above procedure, but double (increase the distance x2) the distance between two pins.
Now you have to measure how many coils are there within 5cm of the two springs.
you'll observe that the second spring has half the coils of the first spring within 5cm.
In here no. of coils is the frequency
5cm length is time.
distance between coil is the wavelength.

why is it important that root hair cells have high ion concentration?
Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption. They also contain lots of mitochondria , which release energy from glucose during respiration in order to provide the energy needed for active transport.

What other planets are like Earth or at least livable on?
What would happen if humans lived at the same time as the big insects?
Answer:
Explanation:
1. The Moon continues to spin away from the Earth, at the rate of 3.78cm (1.48in) per year, at about the same speed at which our fingernails grow. ... The migration of the Moon away from the Earth is mainly due to the action of the Earth's tides
2. Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. ... In addition, the exhaust from cars, trucks, and buses releases nitrogen oxides and sulfur dioxide into the air. These pollutants cause acid rain.
3. Formation. When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle, and a solid crust.
4. The chances of an Ice age are 1.25%
5. I have no answer for that
6. God created earth. It says it in the bible (Genisus.)
7. Cause the sun has not died or bursted...yet.
8. Freezing does not kill germs and bacteria. Instead, it essentially puts them into hibernation. They are inactive while the food is frozen and will “wake up” as soon as the food thaws. And as the food thaws, so will the moisture, which means the bacteria will have the moisture it needs to survive.
9. Cause the core of the earth is trillions of degrees.
10. There would be mass flooding from sea levels rising, severe weather changes, deadly chemical releases, and mass greenhouse gasses that would leak into the atmosphere. Scientists say we need to stop the planet from rising in temperature by just 1° Celsius, or this could happen sooner than we think.
11. Differences in temperature, pressure, and structural formations in the mantle and crust cause magma to form in different ways. ... The rock then cools into new crust. Decompression melting also occurs at mantle plumes, columns of hot rock that rise from Earth's high-pressure core to its lower-pressure crust.
12. I don´t know

HELP!!! A student observes that she's always sleepy shortly after eating lunch, and she wants to be able to pay better attention in her mid-afternoon class. She tried doing 10 jumping jacks just before the class, but still felt sleepy around the middle of the class. The next day, she tried sipping water throughout the class and found that she could pay attention until the end of the class. The student now brings a water bottle to class.
*Identify how this student applied the scientific method to solve her problem.*
Answer:
In this scenario, the student applied the scientific method to solve her problem in that she first established there was a problem, then formulated some hypotheses about why there was a problem, and then did experiments to test the hypotheses.
Explanation:
Hope This Helps!
It's essential for students (and everyone) to stay adequately hydrated throughout the day to maintain overall well-being and cognitive function. Bringing a water bottle to class is a practical and healthy habit that can help the student remain focused and attentive during the class and other daily activities.
Hydration and Cognitive Function: Proper hydration is essential for optimal cognitive function. When the body is dehydrated, it can lead to feelings of fatigue and decreased mental alertness. Drinking water helps maintain the balance of body fluids, and the brain relies on adequate hydration to function at its best.
Blood Flow and Oxygenation: Staying hydrated supports proper blood circulation, including to the brain. Sipping water can help ensure that oxygen and nutrients are efficiently delivered to brain cells, enhancing cognitive performance.
Thirst as a Sign of Dehydration: Feeling sleepy or fatigued after eating lunch could be a sign of dehydration, especially if the lunch is salty or doesn't contain enough fluids. By sipping water during the mid-afternoon class, the student is addressing any potential dehydration and its associated effects on attention and alertness.

Describe the basic function of each of the three leaf tissues
Answer:
Each plant organ (roots, stems, leaves) contains all three tissue types: Dermal tissue covers and protects the plant, and controls gas exchange and water absorption (in roots). Dermal tissue of the stems and leaves is covered by a waxy cuticle that prevents evaporative water loss.
Explanation:
Answer:
Main function of stomata is exchange of gases between the internal tissues and the external atmosphere. Cuticle is present on the outer wall of epidermis to check evaporation of water. Epidermis forms a Protective layer in leaves, young roots, stem, flower, fruits etc

during the calvin cycle, carbon dioxide is _____ to drive the formation of sugars.
Answer:
During the Calvin cycle, carbon dioxide is reduced to drive the formation of sugars.
During the process of photosynthesis, a set of chemical reaction that occurs in the chloroplast is known as the Calvin cycle, which is light independent.
Photosynthesis reaction can be divided into two stages that are the light reaction and the Calvin cycle, in the first stage light energy converted to the chemical energy and the second stage use the products of light reaction to produce sugar.

what is the function of the water monitor lizards claws
Answer:
Claws. These strong, curved claws can tear flesh and inflict fearsome wounds. Water Monitors eat only meat and sometimes tackle prey nearly their own size. Claws may allow the Arboreal taxa to physically separate themselves from the larger monitors of the savannah by living in trees, eliminating them as competition and potential predators.

which human organ is responsible for detoxifying the blood from toxic substances?
The human organ in charge of detoxifying the blood, in addition to a variety of other functions, is the liver.
The liver is the largest solid internal organ of the human body. It is located in the abdominal region. To be precise in the upper right-hand side of the abdomen, just below the diaphragm. The liver has a variety of functions including:
Enzymatic functionsProduction and excretion of bileExcretion of substances (eg hormones)Storage of glycogen and nutrientsDetoxification of bloodamong a few others.
The liver acts as the primary filter for the body's blood. It filters out toxins, breaks down chemicals through enzymatic processes, and removes alcohol from the blood. These processes create waste products known as urea and bile, which are excreted by the liver to be removed from the body by other organs.
