Scientific questions must be...
Answer:
testable
Explanation:
What is the scientific method? Is there just one universal scientific method? Why or why not?
Answer:
"The scientific method describes the processes by which scientists gain knowledge about the world. It's characterized by six key elements: questions, hypotheses, experiments, observations, analyses, and conclusions. These elements are interrelated steps, so they don't always function in the same order."
Explanation:
The scientific method is the process that involves various steps to develop knowledge about the natural world that has characterized the development of science.
The scientific methods involve the following steps in order:
Making a Testable Question. Collecting Background Research. Develop Hypothesis. Design Experiment. Perform Experiment. Collect Data. Analyze dataDevelop Conclusions. Publish FindingsThere is more than one scientific method used worldwide as scientists can add steps, take out steps, revise, therefore, there can not be only one single universal scientific method.

Assume in otters short hair (L) is dominant to long hair (l) and black hair (B) is dominant to brown (b). If you found a black short-haired otter, you could determine its genotype by crossing it to another otter with a genotype of:
Answer:
llbb
Explanation:
The genotype of the black, short-haired otter could be determined by testing-crossing with a brown, long-haired otter whose genotype would be llbb.
Analysis of the resulting zygote from the cross would give an indication of the genotype of the otter - whether it has two dominant alleles each for the black, short-hair traits or heterozygous.
If the otter has two dominant alleles for the two traits, all the resulting zygote from the test-cross would have black, short-hair, but if it is heterozygous, a mixed phenotype set of zygote would be obtained.

Amino acids and sugars are both required by animals to maintain their health. Without a diet containing both of these, animals cannot
survive. Amino acids are obtained by animals when they digest .
A) nucleic acids
B) carbohydrates
C) proteins
D) lipids
Answer:
c
Explanation:
Amino acids are the monomers of protein molecule.Each amino acid molecule is made up of an amine group,caboxylic acid group,Hydrogen atom and R-group. All are attached to the alpha carbon.It is the R-side group that differentiate one amino group from another.
These amino acids units are joined together by the peptide bonds to form the giant protein molecules
The arrangement, the number of the amino acids and the orientation of these amino acids can be used to classify protein into different primary,secondary, tertiary and Quaternary levels.
Generally protein digestion begins and ends in the stomach and the small intestine. by enzymes pepesin and renin, and the activities of enzymes of the pancreas chymotrypsin and trypsin,respectively.
The cells in the wall of the small intestine finally breakdown the digesting protein into amino acids by the activities of the enzymes there.
In prokaryotic cells, regulator proteins bind to a section of DNA called a/an
A)chromatin
B)repressor***
C)promoter
D)operon
“*** is my answer”
Answer:
C) Promoter
Explanation:
Gene expression is the process of synthesizing RNA from a gene (transcription), and subsequently, proteins from mRNA (translation). In both prokaryotic and eukaryotic cells, gene expression is controlled at the transcriptional level, which is regulated by certain proteins called transcription factors. Transcription factors are proteins that regulate the synthesis of a protein from a gene.
Transcription factors regulate the progression of transcriptional process by binding to a regulatory region on the DNA sequence about to be transcribed called PROMOTER. The promoter region is a DNA sequence contained in the OPERON. This binding influences the binding of the transcription enzyme, RNA polymerase in order for transcription to start.
Answer:
I think the best option given the options above would be D) operator.
How did the process of the spontaneous origin of life end?
Answer:
The Greek philosopher Aristotle (384–322 BC) was one of the earliest recorded scholars to articulate the theory of spontaneous generation, the notion that life can arise from nonliving matter. Aristotle proposed that life arose from nonliving material if the material contained pneuma (“vital heat”). As evidence, he noted several instances of the appearance of animals from environments previously devoid of such animals, such as the seemingly sudden appearance of fish in a new puddle of water
A species of lizards migrates to a group of islands in the ocean. Over time, they diversified and evolved into several different species. Each species has a unique jaw shape that allows it to eat its own specific diet. This is an example of
gradualism because one species evolved into several different species over a relatively short amount of time
adaptive radiation because one species evolved into several different forms that occupy different niches
coevolution because the evolving lizard species changed in order to interact with the changing environment
convergent evolution because one species evolved into multiple species that live alongside each other
Answer:
adaptive radiation because one species evolved into several different forms that occupy different niches
No, because its genes are still the same. To evolve would mean that the frog had one set of genes as a tadpole, then a different set as an adult. It just doesn't work that way. The genes are the same.

Scientific method is well-established method used to study biological systems and conduct experiments leading to valid results. in the methods of science, which step generally comes before the other three steps?
Answer:
phycological method
Explanation:
The development of a hypothesis is the step in the scientific method that comes before the three steps.
What is a scientific hypothesis?A scientific hypothesis is an idea that provides a tentative form of explanation for one single phenomenon or a set of phenomena that is observed in the natural world.
Falsifiability and testability are the two primary features of a scientific hypothesis. These are reflected in an “If" or a "then” statement which summarizes the idea presented in such a way that it can be accepted or rejected through experimentation.
The process of the formation and testing of a scientific hypothesis is an important part of the scientific method. The scientific method is the approach used by scientists use when they are attempting to understand and test ideas in the form of a hypothesis that they have observed about natural phenomena.
Therefore, the development of a hypothesis in the scientific method comes before experimentation.

In which condition is relative velocity known by adding the velocity of the first body and that of second body?
Answer:
When the two bodies are moving in opposite direction
Explanation:
The relative velocity of two bodies is found by adding the velocity of one body to the other body when the two bodies are moving in opposite direction
For example, if one body is moving towards the right direction at 5.0 km/hr and the other body is moving left at 1.0 km/hr, the relative velocity of the body moving right relative to the other moving left is given as 5.0 + 1.0 = 6.0 km/hr.
Relative velocity can be experienced when moving up along on an escalator relative to the visible side drive mechanism going down.

Answer:
Biogenesis
Explanation:
Biogenesis has permitted rapid advances in our understanding of structural macromolecules from living cells. Biogenesis theory was first coined by Rudolph Virchow and countered the claim of organisms being in existence according to the Big Bang Theory technique. Biogenesis involves the study of how organisms evolved from smaller ones to become complex.
Biokinetics deals with ways to maintain a healthy body through physical activities. Bio thermodynamics deals with the flow of energy in a biological system while Bioinformatics deals with the use of computer and technology in data analysis.
Remember, carbon dioxide helps to trap the Sun’s heat inside the atmosphere. What might happen to temperatures on Earth if your prediction is true?
Answer:
Temperatures on earth may rise.
Explanation:
Answer:
The temperatures will increase. This will cause global warming that results to phenomenon such as melting of polar ice, increase in ocean and sea levels, and extremities of weather. Carbon dioxide is a greenhouse gas that allows infrared light to pass through but does not allow heat to escape from the earth surface and atmosphere.

Which statement describes one feature of Rutherford’s model of the atom? The atom is mostly empty space. The atom cannot be divided into smaller particles. Electron clouds are regions where electrons are likely to be found. The electrons are located within the positive material of the nucleus.
Answer: The atom is mostly empty space.
Explanation:
Before to Rutherford, the accepted model for the atom was Thomson's model:
The atoms were a positive sphere, with electrons occupying space in it".
This was called the "plum pudding model".
Then came Ernest Rutherford, and he created a model where the atoms are mostly empty space (void) with a positive charged nucleus (really compressed in the center), and the electrons were orbiting around it.
Then the correct option is that the atom is mostly empty space.
Answer:
The atom is mostly empty space
Explanation:
