Some students believe that if they drink a glass of milk before bed and would make them sleep longer what’s the independent variable dependent variable and a control variables
Answer:
Independent variable: Glass of milk
Dependent variable: Time of sleep
Control variable: same type of milk
Explanation:
Independent variable in an experiment refers to the variable that the experimenter manipulates or changes in order to get a response in another variable (dependent). In this case, the independent variable is the GLASS OF MILK taken before bed.
Dependent variable is that 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 TIME OF SLEEP of the students.
A control variable or constant is the variable that is kept unchanged throughout the course of the experiment in order not to alter the outcome of the experiment. In this experiment, a control variable can be the SAME TYPE OF MILK taken by each student.
PLZ HELP :) The light dependent and light independent reactions of photosynthesis work together. The light-dependent reactions trap the energy from sunlight to form ATP and NADPH molecules, giving off oxygen gas. The light-independent reactions use that chemical energy and carbon dioxide to build stable long-term energy storage in the form of:
Group of answer choices
glucose
ATP
water
proteins
The answer is A. Glucose.
Short answer, I had the same question on a quiz.
Long answer, the second phase, AKA the light-INdependent or Calvin Phase, uses that ATP & NADPH from the light-dependent phase & forms glucose to provide long-term energy for the cell to use.
Hope this helps! :)
The light-independent reactions of photosynthesis use the chemical energy in the form of ATP and NADPH, produced by the light-dependent reactions, along with carbon dioxide to build stable, long-term energy storage in the form of glucose. Therefore, the correct option is (A).
What is light-independent reactions?The light-independent reactions, also known as the Calvin cycle, is the second stage of photosynthesis that takes place in the stroma of the chloroplasts in plants. It is named light-independent because it does not require light energy directly, but it does depend on the products of the light-dependent reactions, which are ATP and NADPH.
In the light-independent reactions, carbon dioxide from the atmosphere is fixed into organic molecules using the chemical energy in ATP and NADPH. The first step of the cycle is carbon fixation, where carbon dioxide is combined with a 5-carbon molecule called ribulose-1,5-bisphosphate (RuBP) to form a 6-carbon intermediate, which immediately breaks down into two 3-carbon molecules called 3-phosphoglycerate (3PG). The second step of the cycle is reduction, where ATP and NADPH are used to convert the 3PG into G3P (glyceraldehyde-3-phosphate). Some of the G3P molecules are used to regenerate RuBP, while the remaining G3P molecules can be used to make glucose, sucrose, or other organic molecules.

Gerald is studying the plants and animals of a meadow. He classifies the grasses and clover as autotrophs or producers. Give two pieces of evidence to support Gerald’s classification.
Answer:
First evidence is both are plants.
Second evidence is both uses sunlight.
Explanation:
Grasses and clover are autotroph and can be classified as producer because they has the ability to produce their own food from the process of photosynthesis. Gerald’s classification is right because grasses and clover are plants and we know that plants are the producer of the ecosystem. We can also see that plant is the only organism which uses sun as a source of energy from which it produce their own food.

If a trait is influenced by genes, then it ought to be more highly correlated across pairs of ________ than across pairs of ________.
Answer:
identical twins
fraternal twins
If a trait is influenced by genes, then it ought to be more highly correlated across pairs of identical twins than across pairs of fraternal twins.
What are Twins?Twins are defined as two offspring produced from a single pregnancy, which can either be monozygotic means that they develop from a single zygote, which splits and forms two embryos, or dizygotic means that each twin develops from a separate egg and each egg is fertilized by the own sperm cell.
Identical twins are also called as monozygotic twins which results from the fertilization of a single egg by a single sperm, with the fertilized egg then splitting into two. These share the same genomes and are always of the same sex.
Fraternal twins are called dizygotic twins which result from the fertilization of two different eggs with two different sperms during a single pregnancy. They share half their genome just like any other siblings which may not be of the same sex or look alike.
Thus, if a trait is influenced by genes, then it ought to be more highly correlated across pairs of identical twins than across pairs of fraternal twins.

5. Which type of microscope would be the best tool to use to view the surface of a bacterial cell? Why? Answer:
Answer:
Electron Microscopy. EDS Analysis.
A scanning electron microscope is the best tool for studying the details of the surface of a bacterial cell.
What is a scanning electron microscope?
A scanning microscope or SEM is a microscope in which a focused beam of high-energy electrons is used for to the generation of signals on the surface of solid specimens. These signals are derived from the interactions of electron-sample.
This reveals the information about the surface of a sample which includes external morphology or texture, chemical composition, and structure and material orientation of the sample. In most of the applications of this microscope, the data is collected for the selected area of the surface of the sample and the 2-D image for that is produced which displays spatial variations in these properties.
In a scanning mode, areas ranging from 1 cm to 5 microns are visualised using conventional techniques of SEM techniques. In this, the magnification ranges from 20X to approximately 30,000X with a spatial resolution of 50 to 100 nm.
Therefore, to study the details of the surface, a scanning electron microscope is used.

A certain toxin prevents the mitochondria from functioning properly. Describe the immediate effect this toxin would have on a cell.
Answer:
The cell can't perform its activities.
Explanation:
The immediate effect of this toxin, the cell is greatly affected because mitochondria is the powerhouse of the cell which provide energy in the form of adenine tri phosphate (ATP) by the breaking down of the glucose molecule. If mitochondria does not function properly so there is no energy for the cell and the cell can't perform its activities and our body muscles will be weaker and tired very fast.
If a certain toxin prevents the mitochondria from functioning properly, then the cell won't be able to create energy in the form of ATP. Cellular respiration occurs in the mitochondria.
Mitochondria are the energy centers of the eukaryotic cells where ATP (the energy coin of the cell) is synthesized.Cellular respiration is a series of metabolic reactions by which cells produce energy in the form of ATP from energy from foods and oxygen.This process (cellular respiration) has three stages: glycolysis, the Krebs cycle and oxidative phosphorylation.Glycolysis occurs in the cytoplasm, whereas the Krebs cycle and oxidative phosphorylation occur in the mitochondria.In conclusion, if a certain toxin prevents the mitochondria from functioning properly, then the cell won't be able to create energy in the form of ATP.

1. For each missing word or phrase, circle the choice that correctly completes the sentence. The three main gases that trap heat in Earth's atmosphere are (carbon dioxide / oxygen / nitrogen / hydrogen), methane, and water vapor. They contribute to the (climate / ecosystem / greenhouse / biosphere) effect, which makes Earth's temperatures warmer than they would be otherwise.
Answer:
Carbon Dioxide; Greenhouse
Explanation:
Carbon dioxide, methane, and water vapor all trap heat in the Earth's atmosphere. Because they are trapping the gasses in the atmosphere, they are contributing to the Greenhouse effect, which makes Earth's temperatures hotter/warmer. The "Greenhouse" part is saying that everything underneath the Earth's atmosphere is "housing" the heat and keeping the heat in.
O hipotálamo produz 2 hormônios: ocitocina, que estimula a contração do útero no parto e estimula a liberação do leite marterno; e prolactina, responsável pela produção do leite materno
Answer:
O hipotálamo produz 2 hormônios: ocitocina, que estimula a contração do útero no parto e estimula a liberação do leite marterno; e prolactina, responsável pela produção do leite materno
Explanation:
O leite materno é considerado o melhor alimento para o bebê, por isso é necessário cumprir a amamentação obrigatória nos primeiros seis meses de vida do bebê no caso de ter leite.
As mães que faltam ao leite materno é porque há uma inibição desse eixo entre o hipotálamo, o útero e as glândulas mamárias, os hormônios não são secretados, portanto o órgão alvo não os percebe através de seu receptor e não tem um produto metabólico.
Por outro lado, a ocitocina é um hormônio que promove a contração muscular do útero, gerando trabalho de parto para a expulsão do bebê pelo canal vasginal, essas contrações para iniciar o trabalho de parto devem ser a cada cinco minutos e intensidade Alto.
