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.

Answer:

Scientists try to control most variables in an experiment to find a relationship between the independent variable and the dependent variable

Answer:

Controls are done in order to know if experiments or the subjects being tested are working. Both the control and the subject are compared and observed for change or improvement that will lead to answering to the hypothesis. Since the tested variables will determine the results.

The Circulatory System is about the Blood and the heart: they deliver oxygen to the rest of the body (except lungs). AFTER they deliver the oxygen they get the waste (Carbon Dioxide) and deliver it to the LUNGs (Respiratory System)

The Respiratory system is about the Lungs, Bronchi, Alveoli, Trachea, etc. They EXCHANGE the carbon dioxide from the blood with oxygen, they do this in the ALVEOLI (a small, grape-like sockets in the lungs).

The Digestive System consist the Esophagus, Stomach, Intestines, Gallbladder, and Anus. They Digest the food, they ABSORB the nutrients from the food we eat and we poop out the UNNECESSARY wastes.

 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.

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.

there could be harmful chemicals

Explanation:

The main difference between acellular and cellular organism is that acellular organism doesn't contain cells and cellular organism contain cells.

Answer:

Their structures have to do more things (in an apartment the living room is also the dining room), This analogy applies to cells because simpler prokaryotic cells, which have less structures. It also applies to more complex eukaryotic cells that have more structures, where each structure only does a singular task. (In a mansion each room, only serves one purpose.) I believe it means that even though the homes/cells may appear different, they all include the same basic essentials.

Explanation:

An apartment could represent a prokaryotic cell while a mansion could represent a eukaryotic cell, since the latter is much larger and more complex.

Prokaryotic cells are unicellular organisms that lack membranous organelles and whose genetic material is dispersed in the cytoplasm in an area called the nucleoid. Examples of these type of cells are bacteria, microscopic organism. They are small cells, approximately 1-10 µm, and they have the following components:

On the other hand, eukaryotic cells present organelles with membranes and an organized cell nucleus containing DNA. They are larger than prokaryotic cells, 10-30 µm in size. Examples of eukaryotic cells are the ones that form complex organisms such as animals and plants. However, there are also some eukaryotic unicellular organisms, such as protozoa. They have the following components:

Prokaryotes and eukaryotes vary in several important ways and these differences include structural variation, whether a nucleus is present or absent, and whether the cell has membrane-bound organelles, and molecular variation, including whether the DNA is in circular or linear form. Since prokaryotic cells are so much smaller and simpler, they would be like an apartment, while eukaryotic cells are like a mansion because they are much more bigger, have more structures and are more complex. In a smaller space everything is close at hand, while in a larger space more organization is needed to find things efficiently. Eukaryotic cells, as they form more complex organisms, need to produce more energy and have a larger number of organelles, with more important functions, so the cell needs a larger size to accommodate them.

Therefore, eukaryotic cells resembles a mansion and prokaryotic cells resembles an apartment. This is because of the larger size of the eukaryotes and its cellular machinery which is more complex since it has an endomembrane system which enables greater metabolic efficiency. This allows the separation of functions in the cytoplasm. And prokaryotes are much smaller and simpler, they do not need so much metabolic efficiency or a big size.

pls give brainliest tell me if im wrong

The fraction that Point A on the number line below represent is negative 4 over 8. The correct option is B.

A number line is a picture of a graduated straight line that serves as a visual representation of real numbers in elementary mathematics.

Every point on a number line is assumed to be a real number, and every real number is assumed to be a point.

Number lines are horizontal straight lines with integers placed at equal intervals in mathematics. A number line can represent all of the numbers in a sequence.

The correct answer is -4/8. There are seven marks between 0 and -1, and -8/8 is -1. You count the lines from 0 to A, and you get four lines. Each line represents one eighth.

Thus, the correct option is B.

Two or more tissues working together make up organs in the body.

Tissues are formed of group of cells. they have specific origin and function.

The tissues forms organs and organ system in the body of an organism.

Based on their ability to perform different function and distinct morphology, tissues are classified into four main types.

Epithelial tissues create a protective lining around the delicate organs. They occupy the linings of digestive track, urinary track, etc. Epithelial tissues are protective and secretory in functions.

Connective tissues connect the organs in the body and also present in fat storing cells. Blood is an example of specialized connective tissue.

Muscle tissues have the property of contraction. Skeletal muscle, smooth muscles and cardiac muscles are present in the body of an organism.

Nervous tissues contain specialized nerve cells for the conduction of information and chemical signals from central nervous system to various parts of the body.

Therefore, tissues are important in control, co-ordination and regulation of body functions.
