how is observations used by scientist
Answer:
scientists use observation to collect, and record data, which enables them to construct, and then test hypotheses and theories.
Answer:
yes
Explanation:
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.
Show the energy of Oxidation of two mole pyruvic acid.
Answer:
Methanesulfinic acid (MSIA) is an important intermediate in the oxidation of dimethyl sulfide (DMS) in the marine boundary layer. The oxidation of MSIA by ozone in the gas phase to form methanesulfonic acid (MSA) was investigated using theoretical calculations in this paper. Three pathways can be found for the reaction of MSIA with ozone. The highest energy barrier is 13.02 kcal mol−1 in the most favorable pathway. By comparing the reaction rate of MSIA + O3 with that of MSIA + OH, it can be concluded that the oxidation of MSIA by O3 to form MSA is of minor significance relative to its oxidation by OH radical in the gas phase. This study can provide some information for the theoretical and experimental studies in the significantly heterogeneous and aqueous-phase oxidation of MSIA by O3.
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.

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.

My leg is on fire: a case study on spinal and peripheral nerve anatomy answer
Hello. The question above is incomplete. The full question is:
My leg is on fire: a case study on spinal and peripheral nerve anatomy
Sarah Mitchell is a 68-year-old female who is normally healthy. However, about five days ago she began to feel very fatigued and started to experience a burning and tingling sensation on her right thigh.
You ask to see the area and upon visual inspection you notice 3–4 small, red, swollen areas with vesicles on the posterior aspect of her right thigh. She describes the pain to you, saying "it feels like the back of my leg is on fire and it hurts so bad." She denies being exposed to any excessive heat sources, any changes in her diet, and any changes in the type of body soap, lotion, or laundry detergent she is using. All other physical findings are within normal limits, but her oral temperature is 100.6°F. She complains about being under a lot of stress for the past three months because she has been helping take care of her husband, who is in the end stages of Alzheimer's disease. She has no known drug allergies, is a non-smoker, and attends a water aerobics class twice a week. You suspect she may be suffering from a particular viral infection, so you ask if she had chicken pox as a child. Sarah confirms that she had chicken pox and measles during childhood. Her answer confirms your suspicions that she is likely suffering from shingles (herpes zoster) due to varicella-zoster virus infection.

Answer:
Paresthesia: Term describing the loss of sensation in some region of the body, usually on the tongue, lips and buccal buccal. This loss of sensation occurs with the application of anesthesia in the desired location. Skin vesicle: Term that refers to the appearance of bubbles in the skin. These bubbles may have different sizes, but they all have a liquid inside them. The skin blister can cause itching, tingling and even a burning sensation. Dorsal: Term that refers to the region of the back in the body. It covers the back muscles and is present in the internal and external skeletons. Ventral: Refers to the front of a body and is related to the entire belly. Dormant: Refers to the lack of sensitivity in a muscle. This term is associated with the sense of something that is asleep and unavailable at the moment.Describe the three stages of urine production. Be sure to include how each stage relates to the structure of the nephron and why the composition of urine reveals information regarding the health of the body.
Answer:
Urine is considered to be a true reflection of bodily health because it releases metabolites not necessary for our body.
In some situations, other solutes or secretions are eliminated since they are increasing or are a sign of pathologies.
Clear examples of these situations are: increased protein in urine, presence of hematocrit in urine, presence of glucose in urine, etc.
The three phases of urine formation are: glomerular filtration, reabsorption, and secretion.
Explanation:
The glomerulus and the nephron are responsible for the formation of urine.
Faced with certain pathologies such as diabetes, leukemias, urogenital infections, ketoacidosis, hypercapnia, increased ketone bodies, hyperproteinemias, etc., it is urine that reflects this state of imbalance in the body.
The glomerulus is a filter that is in charge of filtering in a meticulous way those residues of our organism, it releases the unnecessary residues and the chemical compounds or molecules or even cells in excess.
Glomerular filtration is higher or lower in terms of the volume of the afferent and efferent arteries of the renal glomerulus, and the pressures these vessels have within them.
This is how it correlates with the renin-angiotensin-aldosterone system, blood pressure, lungs, nutritional levels, and the overall health of the body.

A blue whale is louder than any animal around.
Go in search of a thing that also makes a loud sound.
The correct answer to this open question is the following.
A blue whale is louder than any animal around.
Go in search of a thing that also makes a loud sound.
Well, talking abound animals sounds, what about the roaring of a lion or a tiger. That is loud too, and scary.
If we do not want to refer to an animal sound, we could talk about the sound of the turbines of an airplane. That is loud. Indeed, floor airport operators have to use earplugs or other kinds of protection to avoid ear damage in the workplace.
The sounds of machines in many industries and factories are also very loud.
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.

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.

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.
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.

Select all that apply.
Answer:
It's B I think
Explanation:
Glycogen, cellulose and starch are all polysaccharides made up of monosaccharides bonded by a glycosidic linkage. Therefore, option (B) is correct.
What are polysaccharides?The most prevalent kind of carbohydrates in food are polysaccharides, often known as polycarbohydrates. They are long-chain polymeric carbohydrates made up of glycosidic connections that connect monosaccharide units. Using amylase enzymes as a catalyst, this carbohydrate may combine with water to create its component sugars.
The polysaccharides starch, cellulose, and glycogen are a few examples of. Polysaccharides are used as stabilisers and dietary fibre in the food industry. Polysaccharides may also be produced by bacteria, for instance while making yoghurt.

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
