6. Name the greenhouse gases.
7. What are some ways humans have contributed to the greenhouse effect?
A portion of the sun's radiation is absorbed by the ozone layer in the stratosphere, preventing it from reaching the planet's surface.
What is the ozone layer?The majority of the UV light from the Sun is absorbed by the Earth's stratosphere's ozone layer, also known as the ozone shield. In comparison to other areas of the atmosphere, it has a high concentration of ozone (O3), yet it is still relatively low in comparison to other gases in the stratosphere.The stratosphere, a region of the atmosphere between 10 and 40 kilometers above us, is where the majority of ozone is found. Here, it serves as a shield to insulate the Earth's surface from the sun's harmful UV rays. Weakness in this barrier would make us more prone to immune system problems, cataracts, and skin cancer.Ozone depletion is the steady lowering of the Earth's ozone layer in the high atmosphere as a result of human activity and the discharge of chemicals including gaseous chlorine or bromine. Particularly over Antarctica, the thinning is particularly noticeable in the polar areas.To learn more about : Ozone layer

what are examples of lipids
Examples of lipids that make up the majority of the cell membrane that isn't protein include fats, oils, waxes, some vitamins (including A, D, E, and K), hormones, and certain vitamins.
Because they are non-polar, lipids are not soluble in water but are soluble in non-polar solvents like chloroform. Organic materials are lipids. They dissolve effortlessly in nonpolar solvents (such as ether) but not in polar ones (e.g. water). With or without other kinds of biomolecules, it often consists of glycerol or fatty acid units. Many lipids are amphiphilic or amphipathic as a result of having both hydrophobic and hydrophilic components.
Lipids come in a wide range of varieties. Common lipids include things like butter, vegetable oil, cholesterol, other steroid hormones, waxes, phospholipids, and fat-soluble vitamins. These compounds all have the trait of being basically water-insoluble yet soluble in one or more organic solvents.

PEASE HELP PLEASE!? List and describe the substrates and products of TCA cycle
Answer:
HOPE THIS HELPS
Explanation:
1. The TCA cycle begins with an enzymatic aldol addition reaction of acetyl CoA to oxaloacetate, forming citrate.
2. The citrate is isomerized by a dehydration-hydration sequence to yield (2R,3S)- isocitrate.
3.Further enzymatic oxidation and decarboxylation gives 2-ketoglutarate.
4. After another enzymatic decarboxylation and oxidation, 2-ketoglutarate is transformed into succinyl - CoA.
5. The hydrolysis of this metabolite to succinate is coupled to the phosphorylation of guanosine diphosphate (GDP) to guanosine triphosphate (GTP).
6.Enzymatic desaturation by flavin adenine dinucleotide (FAD)-dependent succinate dehydrogenase yields fumarate.
7.After stereospecific hydration, fumarate catalyzed by fumarase is converted to L-malate.
8.And the final step of the TCA cycle of NAD- coupled oxidation of L-malate to oxaloacetate is catalyzed by malate dehydrogenase and closes the cycle.

Since they are not all exactly the same number, even though they are near, I would suggest high precision rather than accuracy. Despite being near to one another, they lack precision since no two numbers are exactly the same.
There are two ways to assess observational error: accuracy and precision. Precision measures how closely two measurements are to one another, whereas accuracy measures how close a group of measurements is to its actual value. In other words, precision is a measure of statistical variability and a description of random mistakes. How accurately a measurement reflects how near it is to the actual or acceptable value. Precision is the degree to which measurements of the same thing agree with one another. Accuracy is not necessary for precision. Precision measures the reproducibility of measurements, even when they are far from the acceptable value, whereas accuracy measures how near a measurement is to a known or accepted value. Measurements that are both precise and accurate are repeatable and extremely near to true

4. How does increasing the amount of batteries in a circuit affect the power output?
IV-
DV-
Constants-
While wiring in parallel increases battery capacity, wiring in series boosts voltage.The overall voltage remains constant.This indicates that connecting two 12V 30Ah batteries in parallel would result in a 60 amp-hour battery.
What happens if more batteries are added to a circuit?
A second battery is added to the circuit, which results in a stronger push produced by the two batteries working together to move the charged particles through the circuit more quickly.This increases the amount of charged particles passing through each point in the circuit each second, increasing the current's magnitude. More power components can be added to the circuit to raise the output voltage, which will result in higher voltage output.Because the current must pass through each component in the circuit, the current remains constant and at the same level throughout the entire circuit. All components carry the same amount of current.But when batteries are added in parallel, there is a significant degree of repulsion felt by both batteries at the positive terminals, which lowers the amount of charge on each terminal and lowers the voltage of each battery.Both positive terminals have received the same overall charge as when utilizing a battery. parallel wiring batteries with various voltagesBecause primary (disposable) batteries are not made to hold a charge, they are more prone to overheat, leak, or bulge. In extreme cases where the voltages are drastically different, they may even explode. Higher voltages or current can be supplied by connecting two or more power supplies.Connecting the power supplies in series, setting each one to output the same voltage, and matching each supply's current limit is the simplest way to generate higher voltage. You can enhance the voltage or amp-hour capacity, or perhaps both, by connecting two or more batteries in series, series-parallel, or parallel. This enables higher voltage applications or power-hungry applications. Since the same charge is passed through the same voltage (potential) twice, adding two batteries in series results in an increase in potentials (voltage), but the current flow does not change.For starters, it's crucial to examine the essential adjustments that should be made when charging your battery when discussing batteries that are connected in either series or parallel.In order to power machinery that needs higher voltage levels, batteries connected in series stack their voltages. Using jumper wires, you can join two batteries together in parallel by connecting their negative terminals to one another and their positive terminals to the other.Positive to positive and negative to negative You CAN attach your load to ONE of the batteries, and both will be equally discharged.To learn more about circuit refer
