Photosynthesis photosynthesis takes carbon from the atmosphere but do not get it mixed up with respiration which takes O2 out the atmosphere and replaces it with Co2
Photosynthesis takes carbon from the atmosphere but do not get it mixed up with respiration which takes O2 out the atmosphere and replaces it with Co2.
What do you mean by photosynthesis?Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.
The energy from light causes a chemical reaction that breaks down the molecules of carbon dioxide and water and reorganizes them to make the sugar (glucose) and oxygen gas. After the sugar is produced, it is then broken down by the mitochondria into energy.
Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants. After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose.

Answer:
The surfaces of the leaves of many plants help to reduce water loss because they are not water-permeable. How does the biomolecule that makes up this surface differ from other biomolecules? It is made up of polymers of amino acids. It is made up of long chains of fatty acids.
Explanation:
The biomolecules that make up this surface of leaves differ from other biomolecules by the fact that they are made up of long chains of fatty acids. Thus, the correct option is A.
What are Biomolecules?Biomolecules may be defined as those types of molecules that are significantly present in the body of living organisms and are required to perform essential functions like cell division, morphogenesis, or development.
The long chains of fatty acids typically consist of a hydrophobic arrangement that prevents the movement of water from one part to the other. This specific property of forming a water barrier is only present in fatty acids.
Due to this, the surfaces of the leaves of many plants help to reduce water loss because they are not water-permeable, which means to prevent the migration of water.
Therefore, the correct option for this question is A.

Density involves the amount of a material in a certain volume. When a material changes phases, it changes in density in a predictable way as the amount of material stays the same but the molecules get farther apart or closer together. Water has solid and liquid states that do not follow these predictions of density in the phases of matter.
What does that mean about the densities of the phases of water?
The solid state is the most dense, followed by the liquid state, then the gas state.
The solid state is more dense than the liquid state.
The liquid state is more dense than the solid state.
The gas state is the most dense, followed by the liquid state, then the solid state.

Describe the end result of mitosis in eukaryotes
Answer:
Two genetically identical diploid daughter cells
Explanation:
Mitosis is the process of cell division through which cells proliferate to create new cells. It allows organisms to grow and replace/repair tissues.
Before the cell divides, the diploid cell (two copies of every chromosome) duplicates its genetic material. During the stages of mitosis, the genetic material is divided between two new cells such that each cell contains a complete copy of the genetic information.
Therefore, at the end of mitosis are two genetically identical daughter cells, each with a diploid genome. Each cell is also identical to the starting cell.
Mario and several friends spend a day at the beach.

He decides to research the percentage of Earth's water found in different locations. Which does his research reveal? Multiple choice question. A) Less than 3 percent of Earth's water is freshwater containing no salt. B) The ice caps located at both poles contain 30 percent of Earth's water. C) Fifty percent of Earth's water is in oceans and the glaciers at the poles. D) Ninety percent of Earth's water is in lakes, rivers, and groundwater.
Answer:
A
Explanation:
The correct answer here would be that less than 3 percent of Earth's water is freshwater containing no salt.
Generally speaking, about 71 % of the earth is made up of water. Out of this percentage, approximately 97 % is found in the oceans with less than 3 % being freshwater. About 68.7 % of the freshwater is locked-up as glacier and ice, 30.1 % is groundwater, while the remaining 1.2 % represents surface and other forms of freshwaters which include ground ice and permafrost, lakes, atmosphere, rivers, swamps and marshes, soil moisture, and the freshwater in living organisms.

Why / how does hydrogen bonding help ice cubes float?
Answer:
First, we must understand:
What is Hydrogen Bonding?
Hydrogen Bonding is the interaction between Hydrogen atoms, with their molecules, due to the fact that their (Hydrogen atoms and bonds) are weak that even the other types of bonds are stronger.
(The other bonds are: covalent and ionic bonds)
(Hydrogen bonds are weaker than the average bonds listed above)
If you are to take how and why hydrogen bonds effect/affect ice cubes, we would have to look at how ice cube are formed. If you know, ice cubes can be created due to low temperatures (cold temperatures) making water into a solid. When ice cubes form into a sold, the spacing of the molecules become further apart, creating the density of the overall ice cube lighter than it was allowing it (ice cubes) to float.
An experiment was designed to investigate the effect of caffeine on the heartbeat of Daphnia magna, or water fleas. These tiny, aquatic animals are used because their transparent bodies make it easy to see their hearts and measure their heart rates. Two populations of Daphnia were raised, (A) and (B). Both populations lived in tanks of water at the same temperature and received identical amounts of food. Every 2 hours, water fleas from both populations were selected and their heartbeats were monitored. Population (A) had 0.5 g of caffeine given to them five minutes before their heartbeat was checked. Population (B) were given 0.5 g of water and with no caffeine.
Answer:
This question is incomplete. It is asking to identify the following in the experiment:
Independent variable: CAFFEINE
Dependent variable: HEARTBEAT
Experimental group: POPULATION A, which were given 0.5g of caffeine
Control group: POPULATION B, which were not given caffeine
Constants: SAME TEMPERATURE, SAME AMOUNT OF FOOD, SAME TIME BEFORE CHECKING
Explanation:
Independent variable in an experiment is the variable which is changed or manipulated by the experiment. In this experiment, the independent variable is the CAFFEINE.
Dependent variable is the variable that is measured by the experiment or in other words, the variable that responds to changes made to the independent variable. In this experiment, the dependent variable is the HEARTBEAT measured.
The experimental group of an experiment is the group that receives the experimental treatment (caffeine). In this experiment, the POPULATION A of Daphnia magna, or water fleas are the experimental group because they received 0.5g of caffeine.
On the other hand, the control group is the group that does not receive the experimental treatment. In this experiment, POPULATION B did not receive any caffeine, hence, it is the CONTROL GROUP.
Constant or controlled variable are those variables that the experimenter must keep unchanged for all groups throughout the experiment, in order not to influence the experiment's outcome. In this experiment, the constants are: SAME TEMPERATURE, SAME AMOUNT OF FOOD, SAME TIME BEFORE CHECKING (2hrs)

Work-Rate Problems
There are two equivalent formulas to choose from when solving work-rate problems. If two people are working together on a job then their work rates add and they can perform the job working together in a shorter amount of time. If we let = the time it takes a person to complete a task then his work rate is 1/. In other words, he can complete the 1 job in number of hours. If we let = the time it takes a second person to complete the task and = the time it takes for both people working together we get the following work-rate formulas:
Example: Bill’s garden hose can fill the pool in 12 hours. His neighbor has a hose that can fill the pool in 15 hours. How long will it take to fill the pool using both hoses?
Example: Joe can complete his yard work in 3 hours by himself. If his son helps it will only take 2 hours working together. How long would the yard work take if his son was working alone?
Example: Norm and Cliff can paint the office in 5 hours working together. Being a professional painter, Norm can paint twice as fast as Cliff. How long would it take Cliff to paint the office by himself?
Work-Rate Problem: One small water hose takes twice as long to fill the basin as the larger water hose. If the two hoses working together take 40 minutes to fill the basin how long would it have taken each hose to individually fill the basin?
Work-Rate Problem: Joe can texture and paint a room in 8 hours working alone. It would take Bill 6 hours to do the same job. How long will it take them to complete the job working together?
Work-Rate Problem: Two printers, working at the same rate, work together with printing payroll checks for 4 hours before one breaks down. The other takes 3 more hours to complete the job working alone. How long would it have taken only one printer to complete the job?
Uniform Motion Problems (Distance Problems)
We have set up uniform motion problems using the formula = *. For the following motion problems, we will need the equivalent formula / = to set up the equations.
Example: The first leg of Mary’s road trip consisted of 120 miles of traffic. When the traffic cleared, she was able to drive twice as fast for 300 miles. If the total trip took 9 hours, then for how much time was she stuck in traffic?
Example: A passenger train can travel 20 miles per hour faster than a freight train. If the passenger train can cover 390 miles at the same time it takes the freight train to cover 270 miles, how fast is each train?
Example: Billy rode his skateboard 24 miles to his grandmother’s house for the day. It was a rough ride so he borrowed his grandmother’s bicycle for the return trip. Going twice as fast on the bicycle the return trip took 2 hours less time. What was his average speed on the bicycle?
