Answer:
plant group 1
Explanation:
Because, it is the only one that has not gotten fertilizer
The plant group that is the control group is plant group 1.
What are fertilizers?Any substance of earthy or man-made origin applied to soil or plant tissues to provide plant nutrients is referred to as fertilizers. It's possible to distinguish fertilizers from spreading agents.
The biology student is studying the effect of fertilizers on plants. Fertilizers increase the growth of the plant, and they also affect the soil of the plant in which they grow.
There are three groups of plants that are used. The growth of the first plant is O and 3.0. The growth of the second plant is 5, 3.2, 3, and 10 and the growth of the third plant is 10, 4.4, 20, and 5.0.
By seeing the Table, we can assume that the growth of plant group 1 is most affected and all other plants have similar.
Thus, the plant group is 1.

means
Answer:
A single phospholipid molecule has a phosphate group on one end, called the “head,” and two side-by-side chains of fatty acids that make up the lipid “tails. ” The phosphate group is negatively charged, making the head polar and hydrophilic, or “water loving.” The phosphate heads are thus attracted to the water

B. Dependent Variable=
C. Control=
Answer:
it is an independent variable as it can be changed by studying and also a dependent variable as you can measure her results and see its increase or decrease
Explanation:
hope this helps
could u pls help me with my latest questions pls pls pls pls pls
The variables in the given situation would be as follows:
A). Independent Variable: Amount of time given on study
B). Dependent Variable: Grade in Science
C). Control: Additional Study of 30 minutes
In an experiment or research, an independent variable is described as a variable that remains unaffected by the change in other but rather a manipulation or change in it can affect the other variables. Dependent variables are the variables that receive a direct effect of change in the other variable and therefore, it is the variable that the researcher aims to measure or study.While control helps in making the comparison of the results with or without it. Thus, the given variables are classified in this situation as mentioned above.

Which clue can be used to identify a chemical reaction as a combustion reaction? Oxygen is a product. A hydrocarbon reacts with oxygen. Water and carbon dioxide react. The reaction involves ions.
Answer:
A hydrocarbon reacts with oxygen
Explanation:
The clue that can be used to identify a chemical reaction as a combustion reaction from the options would be if a hydrocarbon reacts with oxygen.
Basically, a combustion reaction is a kind of reaction involving oxygen and another reactant with energy being released in the process. The energy is usually in the form of light and heat.
Thus, following the definition:
Oxygen is rather a reactant, and may not be a product in combustion reactionsWater reacting with carbon dioxide is not a combustion reactionReaction involving ions may not be a combustion reactionThe only reaction that may identify as a combustion reaction is, therefore, the one involving hydrocarbon and oxygen.

Mitochondria differ from chloroplasts in that Group of answer choices mitochondria convert solar energy to chemical energy whereas chloroplasts convert one form of chemical energy to another mitochondria contain three different membrane-bound compartments, whereas chloroplasts contain two mitochondria contain membrane folds called cristae, whereas chloroplasts contain vesicles in stacks called grana mitochondria are not found in plants, whereas chloroplasts are not found in animals
Answer:
mitochondria contain membrane folds called cristae, whereas chloroplasts contain vesicles in stacks called grana
Explanation:
Mitochondria are composed of two membranes (i.e., the inner and outer membranes), which are separated by the intermembrane space. The inner mitochondrial membrane is composed of several folds that form the cristae, which extend into the mitochondrial matrix. On the other hand, in chloroplasts, the inner membrane consists of interconnected stacks of sacs named thylakoids, whose arrangement is known as grana.

What are possible products of glycolytic, or anaerobic, catabolism?
Answer:
The products of a glycolytic metabolism is lactic acid and the increase of the insulin enzyme at the plasma level.
Explanation:
Lactic acid is the product of the reaction of glucose catalysis in oxygen-deficient states such as in anaerobic activity.
Lactic acid is an acid that can be metabolized by the body, which accumulates in the muscles, and is generated once the physical activity has finished or in the last stages.
Insulin, once generating the rest of the activity, or the cessation of the action, comes into play at the plasma level and increases, in order to neoform new energy reserves (glucose) and thus prepare for the next action.
This hormone has the opposite effect to glucagon.

Which of the following statements concerning ribosomes is true?
A. Several ribosomes are often attached to and translating the same MRNA.
B. Ribosomes join amino acids together to form a polypeptide.
C. Ribosomes have one binding site for MRNA and three binding sites for 1RNA molecules.
D. Ribosomes are the organelles responsible for protein synthesis.
E. All of the above statements are true.
Answer:
E. All of the above statements are
Explanation:
Ribosomes are organelles found free floating in the cytoplasm or attached to endoplasmic reticulum (RER). They are the site of protein synthesis in a cell. Ribosomes initiate the translation process by binding to the mRNA molecule using their mRNA binding site. Several ribosomes called POLYSOMES are often attached to and translating the same MRNA molecule.
A ribosome contains four (4) binding sites; one for the mRNA and three (P-site, A-site and E-site) for tRNA, which are small RNA molecules that carry and add amino acid to the growing polypeptide chain during the process. In a nutshell, the ribosome via the aid of tRNA is responsible for joining amino acids together to form a polypeptide chain (future protein).
Ribosomes are complicated macro molecules composed up of nucleic acids and proteins. They are important as they perform a major role in protein assembly and transportation.
The correct answer is:
Option E. All of the above statements is true.
The explanation for the above option is:
The ribosome is located either free or is connected to the endoplasmic reticulum(RER).Ribosomes assist in the translation of the information from mRNA.Polysomes are numerous ribosomes connected to a single mRNA molecule.Ribosomes have one binding position for mRNA and three binding positions for tRNA molecules.The three binding sites for tRNA is (A- site) amino acyl site, (P-site) peptidyl site and (E site) the exit site.Ribosome assembles amino acids to form a polypeptide chain. These polypeptides get transported to the cytoplasm.Therefore all the above statements are true for ribosomes.

Age structure diagrams show the distribution of people of various ages. The diagrams also show the number of people in the prereproductive, reproductive, and postreproductive years. Research and note what else you can infer from age structure diagrams.
Answer:
Age structure diagrams show the following.
The height of the graph indicates life expectancy.
The width of the base shows birth and fertility rate.
The slope of the pyramid-shaped diagram indicates death rate.
Bends in the graph indicate reductions in birth rate or increases in
death rate.
The overall shape of the diagram indicates whether it is an economically developed country or not.
Explanation:
In a stable human population, the age structure diagram looks like a pyramid with a narrower base. The narrower base depicts that the birth rate is low. A stable human population also has a high number of older individuals. A greater number of older people in a population shows that quality of life is high in that area/country and the population has access to nutritional diet, medical care, and healthcare services. These features of the age pyramid in a stable population indicate a developed country. Age pyramids of underdeveloped countries have a wider base (high birth rate) and narrow tip.
