Answer:
The dominant allele
Explanation:
The dominant allele will be expressed because in a heterozygous genotype, the phenotype will always show the dominant gene (in Mendelian genetics)
This is because the dominant allele will dominate the recessive one and it will "mask" the recessive allele.

Using radio telescopes, astronomers have found evidence the new matter is forming in the universe, which is what the big bang theory predicted.
Your answer is B
Well since the big bang theory already supports the idea of new matter forming, we are using new technology to prove an existing theory
In this case, we are using new technology to prove existing theories. NOT making new ones, or modifying them.

an ice cube has the following dimensions :
5.5cm - 8.0cm - 8.4cm
its mass is 340g.Calculate:
a-its volume
b-its density
Answer:
The correct answer would be :
1 volume = 369.6
2. density = 0.9199
Explanation:
Given :
dimensions : 5.5cm - 8.0cm - 8.4cm
Mass : 340 g
Formula :
volume = side * side * side
density = mass/ volume
Solution :
volume of ice cube would be
= 5.5cm * 8.0cm * 8.4cm
= 369.6 m³
density of ice cube would be
= 340/369.6
=0.9199
Thus, the correct answer would be
1 volume = 369.6

Analysis in which general conclusions are drawn from specific observations is called
a. deductive reasoning
b. inductive reasoning
c. reductive reasoning
d. productive reasoning
Answer: Option B
Inductive reasoning.
Explanation:
It is inductive reasoning because inductive reasoning is a type of reasoning in which general informations are made based on some specific observations or information even when the conclusion is not complete guaranteed to be true.
This means that you make a guess's or generalizations based on the information you have at hand.
For example; The left handed people the you know uses left hand in right and you now make the conclusion that all left handed people write with their left hand only.

Answer:
sympathetic and autonomic
Explanation:
Hello there! :D
Firstly, I want to say that some of the written out answers look incomplete. I am going to try my best to answer this question and give you context so that you can choose the best answer choice! :)
There are two main systems within the boundaries our nervous system:
The CNS (central nervous system) and the PNS (peripheral nervous system).
Struturally,
the CNS constistues the brain and spinal chord,
the PNS consistutes your nerves and ganglion.
Functionally, the CNS recieves messages from the PNS and sends messages to the PNS. Think of the CNS as the control center, and the PNS as the reactor.
The PNS has two systems within it, the somatic nervous system, and the autonomic nervous system. The somatic nervous system senses things consciously percieved (ie. eye sight, pain, taste) and the autonomic nervous system senses things unconsciously percieved and controled (ie. stress, anxiety, etc). The point being, you cannot control when it happens or stop the function of it consciously.
The autonomic nervous system holds two main systems, which would be the parasympathetic system and the sympathetic system. The parasympathetic system helps maintain your circadian rythmn, replenish energy, and relax your body. The sympathetic system is known as your "fight or flight" system. This system can be triggered by test anxiety, unsafe situations, and in any case where your life or emotional well being is being threatened.
My best answer for this question, in my opinion, would be the autonomic nervous system, and the sympathetic system. The sympathetic system deals with fear (fight or flight) and is controlled by the autonomic nervous system).
I hope this helps you and you have a wonderful day,

List the monomers and polymers of carbohydrates, lipids, proteins, and nucleic acids.
Answer:
monomer of carbohydrates glucose,sucrose,fructose
polymer of carbohydrates starch,cellulose,glycogen
monomer of protein amino acids
polymer of protein polypeptides
monomer of nucleic acid nucleotides
polymer of nucleic acid DNA
polymer of lipids triglycerides
monomer of lipids 3 fatty acids and glycerol
Monosaccharides are the monomers and polysaccharides are the polymers of carbohydrates. Amino acids are monomers and polypeptides are the polymers of proteins. Nucleotides are the monomers of nucleic acid and polynucleotides are the polymers of nucleic acids. Fatty acids and glycerol are monomers and triglycerides are the polymers of lipids.
What are monomers and polymers?Lipids, Polysaccharides, Proteins and Polynucleotides are the four major groups of macromolecules that are found in the bodies of all living organisms. These are also called biomolecules.
Monomers are small molecules which are generally organic. These molecules combine with other similar monomers which form large molecules. These are polymers. All the monomers can form chemical bonds with at least two monomer molecules.
A class of synthetic substances that are composed of multiples of simpler units or monomers are called polymers. These are the chains of monomers which have a nonspecified number of monomeric units.
Therefore, monosaccharides are the monomers and polysaccharides are the polymers of carbohydrates. Amino acids are monomers and polypeptides are the polymers of proteins. Nucleotides are the monomers of nucleic acid and polynucleotides are the polymers of nucleic acids. Fatty acids and glycerol are monomers and triglycerides are the polymers of lipids.

What is the difference between science and trickery?
Science is- by definition understanding the natural and social world following a systematic methodology based on evidence. Proof is needed, experiments take place etc. Whereas trickery is simply the act of deception, can be for multiple reasons.
However trickery exists in the natural world too in the form of animals using tricks to make themselves look frightening or like another animal. In both cases you cannot believe what you see. The difference would probably be that the tricks science plays can be uncovered by experiments and other observations, but im not sure.
Your question has been heard loud and clear.
Science is basically the logic that explains why things happen and how they occur the way they are , especially with natural phenomena. It is solely used for beneficial purposes so that humans can advance and develop themselves through science.
Trickery is the art mastered by people who just live by using shortcuts and making loopholes out of everything to bypass consequences. It is indeed the complete opposite of science because trickery is not used for improvement like science , but it is used to bring others down while the trickster rises. It is not beneficial for development and advancements. Trickery is however useful to the person using it , and science is useful to the person using it and to the people , but trickery is only beneficial for the person using it , unlike science.

without actually conducting an experiment. Is this
True or false.?
Answer:
it is true
Explanation:
Computer modelling can be defined as the computerization of mathematical models in order to understand the dynamics of biological, physical, and chemical systems. The computerized simulations can be run by using programs that have into account the parameters of the system and thus make predictions that resemble natural experimentation procedures. Examples of computer modelling include, among others, the potential distribution of invasive species, prediction of changes in the genetic structure of a given population over n generations, etc.
