Jorge is conducting an comparative experiment where he is comparing the heights of adults who grew up taking a certain vitamin and adults who did not. He finds that those who took vitamins are, on average, 2 cm taller. What is a major limitation of his experiment?
Answer:
Major limitation of Jorge's experiment are -:
Vast amounts of data can be obtained.He does not prove definitively that a person is taller because of vitamins. No association between vitamins and height can be seen.Explanation:
ABOUT VITAMINS -:
A vitamin is an organic molecule that is an important micronutrient that an organism requires in limited amounts for the proper functioning of its metabolism (or a chemically closely connected group of molecules, i.e. vitamins). In the body, basic nutrients can not be synthesized in adequate amounts, either at all or not, and must therefore be ingested via a diet.
Hence, the major limitations of the experiment are mentioned above.

1. Krista is conducting an investigation to determine how much fertilizer is best for her sunflower plants. She uses five plants and gives each a different amount of water for six weeks. Each week, she measures the height of each plant. She records her findings in a chart.
Answer the following:
1a. What are the independent and dependent variables?
1b. What should she record in the chart?
1c. What kind of scientific investigation is this example?
Answer:
1a. Independent variable: WATER
Dependent variable: HEIGHT
1b. the height of each plant every week
1c. Experimental investigation
Explanation:
The independent variable in an experiment is the variable that is changed or manipulated by the experimenter. In this case, the independent variable is the AMOUNT OF WATER given to each plant.
Dependent variable is the variable that is measured in an experiment. It is the variable that responds to changes made to the independent variable. In this experiment, the dependent variable is HEIGHT.
(1b) In an experiment, the dependent variable is the variable that is recorded. Hence, in this experiment, the HEIGHT of each plant every week is recorded in the chart.
1c) 1c. This investigation is a type of EXPERIMENTAL INVESTIGATION because it involves testing how the independent variable affects the dependent variable.

There are 3 identical plants in 3 identical pots. They are all kept at the same temperature and receive the same amount of sunlight each day. One plant is given a full cup of water everyday, another plant is given half a cup of water every day, and the last plant is given no water. After 3 weeks all of the plants were measured and the results were recorded.
Answer:
If the question is what grew more, than its the plant given a full cup of water everyday.

Can cells survive without support of other cells?
Answer: There are literally countless single celled life forms all over the planet and every creature living is the descendant of single celled organisms. So the answer to your question as written is no, a cell can survive perfectly fine on its own, without the support of other cells, so long as its in a favorable environment.
Explanation:
Answer: No
Cells in bodies of living organisms are designed to help one another, so cells can not live/survive without support of other cells. They work in unity to help our body.

What are the differences between the source of energy of producers and consumer
Answer:
Producers are capable of photosynthesis, a process by which they covert light energy into chemical energy, while consumers use respiration. Producers generate complex organic molecules, while consumers break them down into simpler ones (say, sugars to carbon dioxide, etc.).

Answer:
Answer: insoluble
Lipids are all insoluble in polar solvents like water but highly soluble in the non-polar or weakly polar organic solvents, including ether, chloroform, benzene, and acetone. In fact, these four solvents are often referred to as "lipid-solvents" or "fat-solvents".

A scientist discovers several new prokaryotic organisms near a deep seafloor vent. Which best describes the general characteristics of these organisms?
A.
colonial, autotrophic
B.
multicellular, heterotrophic
C.
single-celled, autotrophic
D.
multicellular, autotrophic
Answer:
a,
Explanation:
The general characteristic of the new prokaryotic organisms is single-celled, autotrophic. Therefore, the correct statement is option C.
What are prokaryotic organisms?Prokaryotic organisms are unicellular organisms that lack a nucleus and other membrane-bound organelles. They can be either autotrophic or heterotrophic.
Deep seafloor vents are chemosynthetic organisms, which produce organic molecules using energy from chemical reactions. Prokaryotic organisms include bacteria and archaea and are the most common types of organisms found in deep-sea vents, and many of these are chemosynthetic and autotrophic.
The new prokaryotic organisms discovered near a deep seafloor vent are single-celled and autotrophic which can produce their food through chemosynthesis.
Therefore, new prokaryotic organisms near a deep seafloor vent are that they are single-celled and autotrophic.

Urey and Miller cooked a "Primordial soup" with Hadean gases, water and electricity to make ___, ___, ___, and ___.
Answer:
Urey and miller cooked a "primordial soup" with Hadean gases, water and electricity to make glucose, acetic acid, amino acids and lipids.
Explanation:
In the Miller-Urey experiment, the aim was to reproduce the conditions of the earth before the existence of life, with the objective of demonstrating the formation of organic matter from inorganic molecules.
The scientists took water and gases present in the Hadean eon —previous to the existence of life— such as methane, carbon dioxide, hydrogen, nitrogen and even ammonia, the primordial soup. This mixture was subjected to electrical discharges, inside closed containers.
The results were some organic molecules, including glucose, acetic acid, amino acids and fatty acids. In these results the presence of macromolecules, such as proteins or nucleic acids, is not appreciated, however it was a significant contribution to the knowledge of the origin of life on earth.
