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: _______________________

Answers

Answer 1

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.

A. This process occurs only in embryonic cells directly after fertilization,
This process only occurs in animal cells because it requires the presence of ribosomes.
This process does not require an input of energy because it is semi-conservative,
D.This process requires the interaction of several different cellular structures,

Answers

Answer:

D.This process requires the interaction of several different cellular structures,

Explanation:

We don't have the information above. However, this process occurs in all cells, and it requires energy. Semi-conservative refers to the fact that, during DNA replication, each new molecule of DNA is made up of one strand of the original DNA molecule and one strand of a new molecule.

The synthesis of proteins from the information in an mRNA molecule does require several structures in the cell, including the nucleus, ribosomes, endoplasmic reticulum and Golgi apparatus.

O a plant scientist who is modifying the genetic information of crop plants in a laboratory

O a conservationist who wants to find water sources in drought-prone places

Answers

Answer:

O a researcher who is investigating selective breeding of livestock

Explanation:

The Human Genome Project (HGP) aims at determining the full nucleotide sequence of the human genome, which can be used for the identification, characterization and mapping of the human genes. The livestock genome sequence exhibits a high level of conservation with the genomes of many mammals including humans. In consequence, the information obtained by mapping genes from the HGP can be of help to map livestock genes. The livestock genome mapping projects have greatly been helped by the increasing availability of human and murine genome sequences, which has been used in comparative genomics for the identification of candidate genes involved in animal traits.

B. The native snail species will move to another area allowing the ecosystem to remain stable.

C. The native snail species will share their food with the invasive species stabilizing the ecosystem.

D. The native snail species will compete for resources with the invasive species and destabilize the ecosystem ​

Answers

Answer:

D. The native snail species will compete for resources with the invasive species and destabilize the ecosystem ​

Explanation:

In Ecology, an invasive species refers to a species of organism that is foreign i.e. non-native to a particular habitat or environment. They are characterized by the ability to proliferate in growth and compete for space and nutrients with the native species in the habitat they are introduced to.

In this case, the giant african land snail, which is an invasive species, if introduced into a stable ecosystem will compete for resources with the native species of that ecosystem leading to the destabilization of the ecosystem.

A student is observing a single-celled alga and knows that it undergoes photosynthesis and respiration. Which question could the student ask to find out how it can do both processes?

Answers

The options associated with the question is :

Are the inputs of photosynthesis the same as the outputs of respiration?

Are the inputs of photosynthesis the same as the inputs of respiration?

Is water needed for the processes of respiration and photosynthesis?

Is carbon dioxide needed for the process of photosynthesis?

Answer:

The correct answer is - Are the inputs of photosynthesis the same as the outputs of respiration?

Explanation:

To understand that it is able to perform both the process photosynthesis and cellular respiration by this single cell of alga it is required to understand the process of both processes and how they provided to the alga.

Photosynthesis is the process that converts water and carbon dioxide into glucose and oxygen as the output or products. Glucose is further used in the cellular respiration with oxygen to produce water and carbon dioxide. So it make balance of the inputs and outputs in the both reaction so it can be understand by asking if the inputs of photosynthesis the same as the outputs of respiration?

Photosynthesis and respiration both are shown by algae because they need light to make food.

Algae are a diverse group of predominantly photosynthetic organisms, including cyanobacteria, green algae, and other eukaryotes. They account for more than 50% of the photosynthesis that occurs on Earth. Photosynthetic efficiency is higher in algae than in higher plants. Algae use carbon dioxide for cellular respiration. It binds CO2 and reduces the amount in the atmosphere.

The questions which students can ask are :

Are the inputs to photosynthesis and the outputs to respiration the same?

Are the photosynthesis and respiration inputs the same thing?

Is it true that water is required for respiration and photosynthesis?

Is carbon dioxide required for photosynthesis?

what are algae?

A group of photosynthetic, aquatic, marine, true root stems leaves bearing organisms.

thus it concludes algae can perform both cellular respiration and photosynthesis.

How does the burning of fossil fuel affect the carbon cycle?

A.The more fossil fuels are burned, the less carbon dioxide enters the atmosphere, less than can be absorbed by plants or the ocean.

B.The more fossil fuels that are burned, the more carbon dioxide enters the atmosphere, more than can theoretically be absorbed by plants or the ocean.

C.The less fossil fuels are burned, the more carbon dioxide enters the atmosphere, more than can be absorbed by plants or the ocean.

D. The more fossil fuels are burned, the more oxygen enters the atmosphere, more than can be absorbed by plants or the ocean.

Answers

Answer:

B.The more fossil fuels that are burned, the more carbon dioxide enters the atmosphere, more than can theoretically be absorbed by plants or the ocean.

Explanation:

The most reasonable answer.

The more fossil fuels that are burned, the more carbon dioxide enters the atmosphere, more than can theoretically be absorbed by plants or the ocean.

What are fossil fuels?

Fossil fuels are made from decomposing plants and animals. Coal, oil, and natural gas are examples of fossil fuels.

When fossil fuels are burned they release a large number of carbon dioxide a greenhouse gas in the air. This leads to increases in the temperature of the globe. If the temperature of the earth increases it leads to the melting of icebergs.

Coal, oil, and petrol are some examples of fossil fuels. Oil releases a huge amount of carbon when burned, approximately one-third of the total carbon on earth.

Carbon dioxide is a greenhouse gas, this gas generally releases trapped heat in our atmosphere.

Therefore, The more fossil fuels that are burned, the more carbon dioxide enters the atmosphere, more than can theoretically be absorbed by plants or the ocean. Option B is correct.
