With the help of an activity show that carbon dioxide is neccessary for Photosynthesis.
Explanation:
To prove the necessity of carbon dioxide in photosynthesis following steps need to do
Insert a part of the leaf of a destarched plant into a conical flask containing potassium hydroxide.
Potassium hydroxide solution absorbs the carbon dioxide gas from the air present in the glass bottle.
Leave the plant sunlight.
After few hours, perform a starch test to this and another leaf of the same plant.
Observation-
Leaf exposed to the atmosphere are bluish black.
Leaf exposed to KOH does not change to blue-black colour
Result- Starch is present in the green part of the leaf.
Conclusion- Presence of starch proves that chlorophyll is necessary for photosynthesis as it traps sunlight.

Why are the lysosomes useful during entrapment of particles?
Answer:
Lysosomes
Explanation:
Lysosomes are membrane-enclosed organelles that contain an array of enzymes capable of breaking down all types of biological polymers—proteins, nucleic acids, carbohydrates, and lipids. Lysosomes function as the digestive system of the cell, serving both to degrade material taken up from outside the cell and to digest obsolete components of the cell itself. In their simplest form, lysosomes are visualized as dense spherical vacuoles, but they can display considerable variation in size and shape as a result of differences in the materials that have been taken up for digestion. Lysosomes thus represent morphologically diverse organelles defined by the common function of degrading intracellular material.
What happens if the amount of withholding taken from your pay is greater than the amount you owe in taxes?
Answer:
When it comes to taxes, less isn't always more because If you don't withhold enough from your paycheck, you may end up surprised at how much you owe Uncle Sam at tax time. And the chances that you are under-withholding taxes are higher than you may think.
Explanation: A 2018 report by the Government Accountability Office (GAO) suggested that a fifth of taxpayers might owe taxes in 2019 due to under-withholding.1 The concern was particularly significant that year due to changes in the 2017 Tax Cuts and Jobs Act. The updated W-4 form from the Internal Revenue Service (IRS) was fully implemented by 2021, and for some, those changes came as a surprise in the form of a more expensive tax bill.
However, no matter what tax year, it's important to withhold the correct amount from your paycheck to avoid underpaying the government.
If the amount of withholding taken from one's pay is greater than the amount owed in taxes, the taxpayer will receive a refund when they file their tax return, as described in Option A.
What is a tax refund?The amount of tax withheld is based on the employee's income, marital status, and the number of allowances they claim on the form, and the employer then withholds the appropriate amount of tax from the employee's pay and sends it to the IRS on their behalf. At the end of the year, the employee must file a tax return with the IRS, which calculates the total amount of tax owed for the year. If the amount of tax withheld from the employee's pay is greater than the amount they owe in taxes, they will receive a refund for the difference.
Hence, the taxpayer will receive a refund when they file their tax return that is present in option A.

Which phrase best describes the need for ion channels?
ions must be able to interact with the charged regions of the cell membrane
o ions need to be sheltered from interacting with the charged regions of the cell membrane
Oso nutrients may enter the cell
O so nutrients may exit the cell
Ion channels are specialized proteins in the plasma membrane that provide a passageway through which charged ions can cross the plasma membrane down their electrochemical gradient. The resulting ionic current, generated by the movement of charged ions through membrane channels, can be measured by patch-clamp methods.
Ion channels must be able to interact with the charged regions of the cell membrane so nutrients can enter the cell.
What are ion channels?
Ion channels are passages in the cell membrane that allow the passage of charged molecules such as
Sodium: Na+Potassium: K+Ions pass from one side to the other of the cell according to the electrochemical gradient. In other words, they go from a place with high concentration to one of low concentration. But to do this, they need to interact with the charged regions of the membrane, which are the ion channels.
