discuss briefly on the origin of life according to creationists and naturalists
Answer:
Creationists believe that a god created everything in the universe, including all life. Typically they don't believe in evolution; they believe that their deity created every species exactly how it's supposed to be and they don't need to change. They believe that everything in nature happens for a planned reason.
Naturalists believe that everything in the universe happens by chance. They believe in theories like the Big Bang Theory, which states that the universe itself was created by chance. They also believe in evolution - that every species adapts to its surroundings and evolves more desirable traits. Naturalists believe that the first life happened due to the correct conditions coming together by chance to create unicellular organisms, which eventually reproduced, mutated, and evolved into the millions of specialized species that exist on earth now.

Which is defined as a cell structure made of DNA that gives all of the master instructions for the cell?
The Nucleus is the cell structure that contains chromosomes which hold the genetic information of the individual.
What do you mean by DNA?DNA stands for Deoxyribonucleic acid. It is one of the most common types of genetic material in most organisms. It is found in both forms single-stranded or double-stranded.
Chromosomes are made up of tightly coiled DNA and consist of proteins known as histone proteins and provide all the master instructions to the cells.
Therefore, the chromosome inside the nucleus is the cell structure made of DNA that gives all of the master instructions for the cell.

Which testing method is considered better than traditional chemical analysis testing?
methods of analyzing trace evidence are more accurate, faster, and can be automated. These include mass spectroscopy, infrared spectroscopy, and gas-liquid chromatography.
The Trace Materials Unit uses methods and techniques to predict items of evidence. Instrumental methods are considered faster in providing results as compared to traditional chemical analysis.
What is the Instrumental method?Instrumental analysis is a field of analytical chemistry that helps to investigate analytes using some sort of scientific instrument.
Many of the instrumental methods can be done for both qualitative and quantitative analysis.
The major categories of instrumental methods are as follows:
Spectral. Electroanalytical. Separatory.Instrumental methods are considered much faster at producing results as compared to traditional chemical analysis. This factor is often important during a crime investigation.
Thus, the instrumental method is considered better as compared to chemical analysis.

Does the King Fish have the same organ of respiration as Dolphins do? Justify your answer
Answer:
Dolphins are mammals, not fish. Unlike fish, who breathe through gills, dolphins breathe air using lungs.
They don't have gills, so they can't breathe underwater like fish. They breathe through a set of nostrils on top of their heads known as a blowhole. While swimming or resting under the water, they can take breathes by exposing only the tops of their heads to the air.
Like all mammals, dolphins have lungs and breathe air. They are the organ of the respiratory system which process the air inhaled through the spiracle.

Which compound is inorganic?
O A C6H1206
O B. KH2PO4
OC. CH3COOH
OD. C2H6
O E. C2H5OH
Answer:
KH2PO4
Explanation:
Organic compounds generally contain carbon and hydrogen.
Inorganic compounds are formed using other elements in the periodic table.
The right response, KH2PO4, is Option B. Since KH2PO4 is an inorganic substance, it doesn't include carbon. Potassium, hydrogen, phosphorus, and oxygen atoms make up the ionic composition. It is a potassium and dihydrogen phosphate anion salt that is used as a food ingredient and fertiliser.
What are organic substances ?Contrarily, organic substances are those that have carbon and hydrogen atoms in them. The organic molecules C6H1206, CH3COOH, C2H6O, and C2H5OH are a few examples.
These substances differ from inorganic substances in that they include carbon atoms. As KH2PO4 is an inorganic chemical, Option B is the best choice for the right response. Contrarily, organic chemicals are not inorganic since they include carbon atoms.
There are two types of compounds that are organic and inorganic and these both of the molecules are possessing different types of varieties and with that varies as per the compounds and the qualities and with these different types of compounds are made.

A trait I which the alleles are not dominant over one another
Answer:
They are co-dominance and incomplete dominance.
Explanation:
Co-dominance occurs when both alleles in a heterozygous genotype for a trait are both equally expressed. An example is the human AB blood group, in which both the A and B alleles are equally expressed.
Incomplete dominance occurs when the heterozygous genotype for a trait is expressed as a blend. An example is blue feather color in chickens, in which a black allele and white allele together are expressed as blue feather color.
Energy efficiency = useful energy output/total energy input x 100(%)
If a power plant uses 100 units of energy to create electricity and the output is 5 units, where does the 95% of the energy input go?
A: Lost as heat
B: Lost as gas
C: Escapes the system as potential energy
Answer:
no
Explanation:
No, a real machine can't have an efficiency of 100%. An efficiency of 100% means that there is no loss and the output energy (or work) of the machine is equal to input energy (or work). In real machines, there is always some loss of energy to overcome friction and air resistance
Look at the table you filled in above. How does the numbers for how much the snakes are consumed compare to how much these predators consume other organisms in the habitat (particularly mammals)? What could be a reason for the differences?
The number of organisms decreases on movement from producers to consumers in a food chain. This happens due to decreased energy levels at higher trophic levels.
What is a food chain?Food chain is the sequence of matter and energy transfers as food from one organism to another.
Food chains interconnect locally into a food web as most organisms consume more than one type of animal or plant.
The number of organisms decreases on movement from producers to consumers in a food chain. This happens due to decreased energy levels at higher trophic levels.
Thus, it can be concluded that this is the main reason behind the number of snakes consumed as compared to other organisms.
