Answers
Answer:
Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane. Gas exchange in gills and lungs operates by this process. Carbon dioxide is produced by all cells as a result of cellular metabolic processes.
Explanation:
The diffusion of a substance into or out of a cell requires a process called diffusion, by which the molecules pass out through the plasma membrane.
What is diffusion?Diffusion is a key mechanism for material transfer within cells and for the passage of critical tiny molecules across the cell membrane. This process controls the exchange of gases in the gills and lungs. All cells release carbon dioxide as a byproduct of biological metabolism.
There are two processes by which the molecules pass through a semi-permeable membrane. The processes are osmosis and diffusion. When the material transfer from low concentration to higher concentration.
Thus, diffusion is the process by which molecules travel through the plasma membrane to allow material to enter or exit a cell.

Answer:
The lagging strand contains Okazaki fragments
Explanation:
During DNA replication, the two strands of DNA are separated and replicated via distinct mechanisms.
The leading strand is synthesised continuously by DNA polymerase in the 5'-3' direction.
However, DNA polymerase can only work in one direction (5'-3') so the other strand cannot be synthesised continuously in the reverse direction.
The other strand, the lagging strand, has to be synthesised discontinuously in the 5'-3' direction. This forms fragments- called Okazaki fragments - that are later joined up.
This is much easier to visualize than to explain, check out the video titled "DNA replication - 3D" on Y0utube by yourgenome to see it in action!

A study was created to test the effects of jazz on people’s sleep patterns. The hypothesis of the experiment was that if people listened to jazz music as they fall asleep, they will sleep for longer periods of time. For the experiment, 2 groups of people were created. One group was placed in a quiet room where they went to sleep and they were timed on how long they slept. The other group was placed in a room where jazz music played softly as they began to sleep and played throughout the night. As each group awoke, their sleep times were monitored.
Dependent Variable: ______________________ Control Group: ____________________________
Independent Variable: _____________________ Experimental Group: ________
Answers
Answer:
Dependent variable - sleep times
Independent variable - jazz music/silence
Control group - Group 1. The group that was kept in a silent room
Experimental group - Group 2. The group placed in a room with jazz music.
Explanation:
The dependent variable is the actual variable to be measured during an experiment. The value of the dependent variable is dependent on the independent variable supplied. In this case, the dependent variable is the duration of sleep of the different groups.
The independent variable is supplied by the experimenter and is often manipulated to see the effects it will produce on the dependent variable. In this case, the jazz music and the silence in the rooms respectively represent the independent variable.
The control group receives no treatment variable and represents the group that is often used as the benchmark to measure the effects of treatment variables on experimental subjects. In this case, the control group is the group that was placed in a room without jazz music.
The experimental group is the group that receives the treatment variable and in this case, the group that slept in the room filled with jazz music.
Dependent Variable: The dependent variable in this experiment is the sleep duration or the length of time each participant slept.
Control Group: The control group in this experiment is the group of people placed in a quiet room where they went to sleep without any jazz music playing. This group serves as a baseline for comparison to evaluate the effects of jazz music on sleep duration.
Independent Variable: The independent variable in this experiment is the presence or absence of jazz music while falling asleep and throughout the night.
Experimental Group: The experimental group in this experiment is the group of people placed in a room where jazz music played softly as they began to sleep and continued to play throughout the night. This group is exposed to the independent variable (jazz music) to test its effect on sleep duration.
The purpose of this study is to determine if the independent variable (jazz music) has an impact on the dependent variable (sleep duration) by comparing the control group's sleep duration to that of the experimental group.

After checking the cracker package, the students were surprised to find that protein and fat are not listed on the nutritional label. No other groups in their class have results that show protein and fat present in the sample. Describe one factor that couldcontribute to their erroneous results:
Answers
Answer:
The tubes used in the lab were not thoroughly cleaned out and contains substances with proteins and lipids.
Explanation:
Proteins and lipids are macromolecules and polymers made of monomeric units. In the experiment, the error was due to the reuse of the contaminated test tubes. Thus, option B is correct.
What are proteins and lipids?Proteins and lipids are the major biological molecules that are polymers and made of smaller units (monomers) linked together by various chemical bonds. The proteins are made of amino acids and lipids are made of fats and glycerol.
The errors in the cracker experiment can be due to the presence of contaminated, re-used test tubes that might have residuals left of fats and proteins in them. The contaminants affect the results and interfere with the biochemical tests.
Therefore, option B. the re-used test tubes might have protein and fat contaminants.

You need to find out why the GBR water is inhibiting (stopping) photosynthesis in the algae. The three major parts of photosynthesis are PSI, PSII and the Calvin cycle. The database has provided 3 things that could be inhibiting photosynthesis: high sea temperatures, paraquat, and diuron.
Answers
Answer:
Explanation:
The question is not complete below is the remaining part of the question
Justify your choice by writing a hypothesis to explain how it has stopped the algae from making ATP, NADPH and sugars. You will be able to revise your hypothesis as you do more experiments
Explanation:
The hypothesis will be
High sea temperature inhibit Algae growth
Herbicides reduces algae photosynthesis rate
Algae respond to temperature differently some thrive at a low temperature, some at a moderate temperature but when the temperature is very high the rate of photosynthesis will reduce because they can not undergo the normal body physiological function as a result of harsh environment. In green plant at a very high temperature stomata closes to regulate water loss this prevent Carbon dioxide from coming in and photosynthesis rate reduces
Paraquat and Diuron are herbicide that prevent the growth of plants, when they are sprayed Algae is affected they die from immediate action of this chemical and their colour changes since chloroplast the green pigment is where light hit for photosynthesis to occur when the color changes the active site is affected photosynthesis can no longer occur.
Answer:
Diuron
Explanation:
Increasing the temperature only decreases the sugar, not the ATP and NADPH. I predict that Diuron will be inhibiting photosynthesis because photosynthesis as a whole should not work if Photosystem II is interfered with. Also, because Paraquat only lowers NADPH and sugar and not ATP, Diuron is the only choice left.
