Explanation:
1. 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: _______________________
Answer:
Independent variable: Jazz
Dependent variable: Amount of time used to sleep
Control group: The group that was placed in a quiet room
Experimental group: The group that was placed in a room where jazz music played softly
Explanation:
In an experiment, the independent variable refers to the variable being changed or manipulated by the experimenter in order to bring about a measurable response. In this experiment, the independent variable is the JAZZ used.
Dependent variable is the variable that is measured in an experiment. It is the variable that responds to the changes made to the independent variable. In this experiment, the dependent variable is the AMOUNT OF TIME SPENT SLEEPING.
Control groups are the groups in an experiment that do not receive the experimental treatment (jazz music). Hence, the GROUP THAT WAS PLACED IN A QUIET ROOM is the CONTROL GROUP.
Experimental group, on the other hand, is the group that receives the experimental treatment in an experiment. In this case, the experimental group is the GROUP THAT WAS PLACED IN A ROOM WHERE JAZZ MUSIC WAS PLAYED SOFTLY.

Which of the following most likely indicates that a chemical change has
happened?
A. A plate breaks when it falls to the floor.
B. There's a loud sound when a jet airplane starts its engines.
C. An icicle melts in the sun.
D. A can is crushed when it is stepped on.
Answer:
Option B
Explanation:
A plate breaking when falling to the floor would be a physical change, not chemical, as what the plate is created from would not change.
An icicle melting in the sun would be a physical change, as an icicle is frozen water, and after melting it would be normal water.
A can being crushed is still just a physical change, as the material making the can(typically aluminum) has not changed.
When a jet airplane starts its engines, fuel is combusted, creating energy for the engines to start. This would create the loud noise. As fuel is combusted, it turns into different things, henceforth the sound would imply a chemical change has occurred.

Which is not true about mitosis A. The chromosomes in the daughter cells are half the number from the parent cell B. The chromosomes in the daughter cells are the same number as the parent cell C. Each nuclei is identical to the parent nucleus D. The four main stages of mitosis are prophase, metaphase, anaphase, and telophase
The chromosomes in the daughter cells are half the number from the parent cell. So, the correct option is (A).
What is Mitosis?Mitosis is defined as the part of the cell cycle in which the duplicated chromosomes are divided into two new nuclei. Cell division by mitosis gives rise to genetically identical cells in which the total number of chromosomes remains the same. Hence, it is also known as Equilateral Partition.
The phases involved in the mitosis are :-
ProphasePrometaphaseMetaphaseAnaphaseTelophase.Mitosis occurs in somatic cells which occurs in all types of cells that are not involved in the production of gametes. Each mitotic division contains one copy of each chromosome, thus a complete set of chromosomes is found in the nucleus of each new cell.
Thus, the chromosomes in the daughter cells are half the number from the parent cell. So, the correct option is (A).

What is the anatomy of a leaf
Answer:
Typically, a leaf consists of a broad expanded blade (the lamina), attached to the plant stem by a stalklike petiole. In angiosperms leaves commonly have a pair of structures known as stipules, which are located on each side of the leaf base and may resemble scales, spines, glands, or leaflike structures.

3.How does DNA polymerase move along each strand of DNA? A.Both move towards the replication fork B.Both move away from the replication fork C.One moves towards from the replication fork and the other moves away from it D.There is only one DNA polymerase on the DNA at a time
4.How can each copy of DNA at the end of replication be compared? A.Each copy is identical to each other B.Each copy is different from each other C.They are 90% similar D.They are 50% similar
5.In the event of a mismatched nucleotide , which molecule is able to backtrack , "proofread ," and correct the nucleotide sequence? A.DNA Proofreadase B.DNA Polymerase C.DNA Helicase D.DNA Primase
Answer:
1) Transcription Bubble.
2) Replication Forks
3)
Explanation:
1) The region of opened- up DNA is called a Transcription Bubble. In transcription, a region of DNA opens up. One strand, the template strand, serves as a template for synthesis of a complentary RNA transcript.
2) The Replication Forks hold the 2 separated strands of DNA apart, preventing then from assuming their double helix shape... in order to replicate all your DNA its faster to replicate DNA if your doing it in many different areas at the same.
3)Since DNA polymerase requires a free 3` OH group for initiation of synthesis, it can synthesize in only one direction by extending the 3` end of the preexisting nucleotide chain. Hence, DNA polymerase moves along the template strand in a 3`-5` direction, and the daughter strand is formed in a 5`-3` direction.

Replication bubble.Replication fork One moves towards from the replication fork and the other moves away from it..Each copy is identical to each otherDNA PolymeraseWhat is DNA replication?A double-stranded DNA molecule is copied to create two identical DNA molecules through the process of DNA replication. Because every time a cell splits, the two new daughter cells must have the same genetic material, or DNA, as the parent cell, replication is a crucial process.
A particular kind of enzyme called DNA polymerase (DNAP) is in charge of creating fresh nucleic acid molecules that are copies of the original DNA. Polymers are huge compounds consisting of smaller, repeating units that are chemically linked to one another. Nucleic acids are polymers.

Lentic Systems and give examples
Answer:
Lentic is a class of aquatic ecosystems that are found on land, such as:
ponds
rivers
lakes
swamps
streams
Mostly, lentic ecosystems are described as still bodies of freshwater, and they are smaller ecosystems. Some lentic ecosystems contain animals and microorganisms, but they mostly rely on the photosynthesis of algae and underwater plants to produce energy to thrive. One of the requirements of a lentic body of water is that it is exposed to the sun to encourage photosynthesis.
Explanation:
A lentic ecosystem entails a body of standing water, ranging from ditches, seeps, ponds, seasonal pools, basin marshes and lakes. Deeper waters, such as lakes, may have layers of ecosystems, influenced by light. Ponds, due to their having more light penetration, are able to support a diverse range of water plants.

The top of the saturated zone is known as A. the aquifer B. the water table C. the unsaturated zone D. spring rock
Answer:
B. the water table
Explanation:
The question above is related to the topic on "Groundwater."
Groundwater is considered "fresh." It falls into the soil and gets soaked in it. It can stay stored for many years. It is very beneficial because it serves as a source of water for many residential places.
The storage of groundwater relies on two zones: unsaturated zone and saturated zone. The unsaturated zone is the first layer under the surface area of the land. It is followed by the "water table," which lies a little farther from the land surface. After which is the saturated zone where you can find particles of different rocks.
The top of the saturated zone is known as the water table. Therefore, option (B) is correct.
The water table divides the saturated zone, where water fills the crevices between soil or rock particles, from the unsaturated zone, which is air-filled. Precipitation, groundwater exploitation, and seasonality affect the water table. It controls groundwater supply and flow.
Spring or surface water bodies can form where the water table meets the land. Managing water supplies, analysing groundwater flow patterns, and assessing groundwater contamination require water table monitoring.
