Answer:
C
Explanation:
The error that the student made was to place the containers for the different fruits in different areas around the school.
In order to ensure that each contain receives the same treatment, they should have been placed in the same area around the school. Different areas around the school might have varied populations of fruit flies, hence, jeopardizing the result.
The containers should have been subjected to the same conditions in order to ensure an unbiased outcome.
The correct option is C.

How do particle speed relate to the distance between particles
Answer:However, particles will move in straight lines until they collide with something. Collisions usually change the speed and direction of the particles movements. If the motion of particles slows the particles move closer together. This is because the attraction between them pulls them toward each other.
Explanation:
Larger particles move slower, due to their larger mass and may be influenced by numerous collisions with many nearby smaller particles. Smaller particles move faster. ... Hotter particles move faster because they have more energy. The rate of diffusion increases as temperature increases because the particles move faster. You're welcome :) - xoxo madster

Which answer choice BEST supports the idea that the Scientific Revolution questioned the established ways that Europeans understood the world around them? A During this time, philosophers and thinkers in Asia, the Middle East, and Europe developed ideas and theories about how the Universe functioned, and then used mathematics to support their ideas. B This revolution was, in part, a response to the flood of new ideas pouring into Europe as a result of its expanded contacts with the rest of the world. C Europeans were able to collect and form new knowledge, and this led to Europe's unmatched power in the centuries that followed. D This way of thinking challenged the idea that the Bible was the source of all human knowledge, both historical and scientific.
Answer:
C. Europeans were able to collect and form new knowledge, and this led to Europe's unmatched power in the centuries that followed.
Explanation:
Scientific Revolution occurs in the Renaissance period in which the transition of Europe occurs from middle age towards modern era. This change occurs due to scientific revolution in the Europe. People at that time focus on obtaining knowledge and performing new research and experiments in order to obtain more knowledge and invent new technologies which make them powerful in the coming future.

Prokaryotic cells do not contain many of the organelles that eukaryotic cells have. Prokaryotic cells do have a primitive form of _____________.
A.) ribosomes
B.) Golgi apparati
C.) mitochondria
D.) chloroplasts
Answer:
Ribosomes
Explanation:
Prokaryotic cells do have a primitive form of ribosomes. Thus, the correct option for this question is A.
What are Prokaryotic cells?Prokaryotic cells may be defined as the types of cells that lack a well-defined nucleus and other membrane-bound cell organelles. The genetic material of a prokaryotic cell is a single chromosome made up of a single strand of DNA.
A Prokaryotic cell typically has a cell membrane or plasma membrane that functions or operates like a protective cover. Golgi apparatus, mitochondria, and chloroplasts are significantly absent in prokaryotic cells. This is because they are membrane-bound cell organelles.
The traces of ribosomes are required for the process of protein synthesis in order to accomplish metabolic activities required for the survival of prokaryotic organisms.
Therefore, prokaryotic cells do have a primitive form of ribosomes. Thus, the correct option for this question is A.

Human muscle cells are examples of what type of cells?
prokaryotic
eukaryotic
bacteria
plant
Answer:
Eukaryotic
Explanation:
Answer:
Eukaryotic cells
Explanation:
Human cells have organelles, and so do eukaryotes. Prokaryotes, on the other hand, do not have any organelles and can be seen in small microorganisms such as bacteria.
Plants is not an option becuse plant cells make photosynthesis and human cells (a type of animal cell) do not, as we are missing the chloroplasts necessary for photosynthesis.

Explanation:
proteins are made up of 21 different L-amino acids. these amino acids are joined together with peptide bonds. peptide bond is a bond between a caboxylic group of one amino acid with amino group of other amino acid.
following is a figure to describe the structure of a single amino acid, where R -group is variable and can contribute for the amino acid to be neutral, acidic or basic. next figure gives an idea of how many various amino acids are there.
Will water that contains no solute ever stop flowing into a hypertonic solution through osmosis?
Answer:
No, it will never stop flowing
Explanation:
Osmosis is the movement of water from an area of lower concentration of solute to an area of higher solute concentration through a semi-permeable membrane. If one side of the membrane is completely free of solute, water will move to the hypertonic solution continuously in a bid to achieve equilibrium until all the water completely moves to the hypertonic side. This is because equilibrium cannot be attained since one side is completely void of solute and another has solutes.
It is like having red coloured paint on one side and water on another side of a membrane, and the water moves into the paint compartment and only stops when they both have the same color. No matter how much water moves across, they cannot have the same color on both sides.
What do DNA and RNA code for?
Answer:
The genome of an organism is inscribed in DNA, or in some viruses RNA. The portion of the genome that codes for a protein or an RNA is referred to as a gene. Those genes that code for proteins are composed of tri-nucleotide units called codons, each coding for a single amino acid.

Which statement describes why hypotheses are valuable, even if incorrect? Select one: a. Adds to existing knowledge b. Answers a defined problem c. Allows theories to be proven d. Allows theories to be disproved A theory doesn't get disproved without large amounts of da
Answer:
The correct option is a: "Adds to existing knowledge"
Explanation:
A hypothesis is an idea that is brought forth based on an observation. It needs to be tested by carefully and thoroughly planning an experimental design that either supports or refutes the hypothesis. So even if it comes out to be incorrect, it still allows us to understand some aspect of a phenomenon that was unknown till then.

What do all living cells have in common? 1. A cell membrane and genetic material 2.Chloroplast and mitochondria 3. A cell wall and cell membrane 4. A nucleus and genetic material
Answer:
one.
Explanation:
nuclei aren't present in prokaryotes, a cell wall/chloroplasts are a part of plants. the basic beings just need a cell membrane (to separate it from it's environment) genetic material, to get information to code proteins, and ribosomes, to create proteins.
All living cells have a cell membrane and genetic material. The correct option is 1.
A cell membrane, also known as the plasma membrane, is a fundamental feature of all living cells.
It is a thin, flexible barrier composed of lipids and proteins that surrounds the cell and separates its internal contents from the external environment. The cell membrane regulates the passage of molecules, ions, and other substances in and out of the cell, maintaining an internal environment necessary for cellular processes.Genetic material refers to the hereditary material that carries the genetic instructions for the functioning, development, and reproduction of living organisms.
In most cells, the genetic material is in the form of deoxyribonucleic acid (DNA).DNA contains genes, which are specific sequences of nucleotides that encode the information necessary to build and maintain an organism.All living cells have a cell membrane that serves as a boundary and a genetic material, usually in the form of DNA, that carries the instructions for the cell's functioning and inheritance. These two components are essential for the basic structure and processes of all living cells.
Thus, the correct option is 1, A cell membrane and genetic material.
