Answer:
Suzie can measure the HEIGHTS of the plants in metres (m) or centimeters (cm)
Explanation:
According to this question, Suzie Q wants to know how different colors of light effect the growth of plants. She sets up the experiment by exposing 5 ferns of the same species to different colors of light (white, blue, green, red).
After ensuring that some variables called constants like same 20 mL of water, same fertilizer (miracle-grow) etc are the same for all ferns, She then measures the growth of each fern placed under different colors of light.
The independent variable in this experiment is the different colors of light while the dependent variable is the growth of the plants. This question is asking for how Suzie could measure the dependent variable (growth). Suzie can measure the growth of the ferns placed under different colors of light by RECORDING THE HEIGHTS OF EACH FERN IN cm or m.

Two or more tissues working together make up organs in the body.
What are tissues?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 tissueConnective tissueMuscle tissueNervous tissueEpithelial 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.

A group of students hypothesizes that the amount of alcohol produced in fermentation depends on the amount of glucose supplied to the yeast. They want to use 5%, 10%, 15%, 20%, 25%, and 30% glucose solutions. 1)What is the independent variable? 2)What is the dependent variable? 3)What control treatment should be used? 4)What variables should be standardized (controlled)? 5)What type of graph is appropriate for presenting these data?
Answer:
1) Glucose solutions
2) Amount of alcohol
3) Water
4) Yeast
5) Bar chart
Explanation:
1) Independent variable is the variable that is "intentionally altered" by the researcher only and is not affected by any other variable. The Independent variable in the question is the glucose solutions.
2) Dependent variable is the variable that is as a result of the independent variable. The dependent variable in the question is the amount of alcohol.
3) The control treatment that should be given to the control group should be water. The control group is the group in which other groups are usually compared to and are hence given the control treatment.
4) Control variable is the variable that is kept constant throughout the course of an experiment. The control variable in the question is the yeast.
5) The type of graph that will best represent these data is the bar chart. The glucose solution will be on the x-axis while the amount of alcohol produced will be on the y-axis.

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

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.

As a group, discuss the opening analogy of an efficiency apartment and a mansion as it relates to cells. Record your final consensus of how this analogy applies to cell structure.
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:
Cell membrane Cell wall Cytoplasm Nucleoid Plasmids Ribosomes Periplasm Flagellum Capsule Pili or fimbriae GlycocalyxOn 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:
Cell membrane Cell wall (in plants) Cytoplasm Mitochondria Chloroplasts Ribosome Lysosome Golgi apparatus Smooth Endoplasmic Reticulum Rough Endoplasmic Reticulum Centriole Flagellum (not in all) Vacuole Microtubules VesiclesProkaryotes 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.

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.

"Francesco Redi was a scientist that performed an experiment to determine whether maggots formed from rotting meat. Versions of his experiments are described below. Meat was placed in two beakers. One of the beakers was left open to the air. The other beaker was covered with a fabric that only allowed air to get in. As the meat rotted, flies landed on the meat in the open beaker but were unable to get to the meat with the fabric over it. After a few days, maggots appeared on the meat in the open beaker, but not in the closed beaker. In the next experiment, rotting meat was placed in two beakers. Dead flies were placed in one beaker, and live flies were placed in the other beaker. Both beakers were sealed, allowing no air in. Maggots appeared in the beaker with live flies, but not in the beaker with dead flies." 1. Explain how this experiment disproves the theory of spontaneous generation. (3 points)
Answer:
Francesco Redi performed an experiment explained in the question to confirm wheather maggots formed from roeeting meat. He explained that maggots on meat do not form spontaneously.
These maggots come from the eggs laid by flies on the meat as it is only found on open meat jar where flies can go and lay their eggs. It disaproves the spontaneous generation thoery as if it was true open jar or closed jar every rotting meat jar must carry maggots on them.
