Answer:b,c,e
Explanation:
The correct options are:
B. All cells in a single organism contain the exact same DNA.
C. DNA makes RNA which makes protein.
D. DNA is single-stranded
E. RNA contains uracil
What is DNA?Deoxyribonucleic acid, also known as DNA, is the molecule that carries the genetic material necessary for an organism's growth and operation. The structure of DNA is a double helix, which is made up of two connected strands that loop around one another to resemble a twisted ladder. Deoxyribose and phosphate groups alternately form the backbone of each strand. One of the four bases—adenine (A), cytosine (C), guanine (G), or thymine (T)—is joined to each sugar.Adenine forms chemical bonds with thymine while cytosine forms chemical bonds with guanine to join the two strands together.
All DNA is used to code for proteinsProtein-coding genes make up only around 1% of DNA; the remaining 99% is non-coding. Protein synthesis instructions are not found in noncoding DNA.
All cells in a single organism contain the exact same DNA.Yes, our body's cells all begin with identical copies of the same DNA.DNA makes RNA which makes protein.An explanation of the transmission of genetic information within a biological system is the core principle of the central dogma of molecular biology. "DNA makes RNA, and RNA makes protein,"
DNA is single-strandedSingle-stranded (ssDNA) and double-stranded (dsDNA) DNA are two different types of DNA. Two strands of DNA loop around one another to form double helices, which are dsDNA. ssDNA can fold into various forms, although it typically takes the form of a stellate or star. Only a few viruses use ssDNA to store genetic information, while the majority of organisms use dsDNA to encode genetic information.RNA contains uracil
Adenine, cytosine, uracil, and guanine make up the four nitrogenous bases that makeup RNA. The pyrimidine uracil is structurally related to the pyrimidine thymine, which is present in DNA. Uracil can base-pair with adenine, just like thymine.
Therefore, options B, C, D, and E are correct.

Describe in three paragraphs how the actions of the entire human race contribute to (or take away from) the amount of ENTROPY in the universe.
Answer:
At the moment of the Big Bang, almost all of the entropy was due to radiation, and the total entropy of the Universe was S = 1088kB. On the other hand, if we calculate the entropy of the Universe today, it's about a quadrillion times as large: S = 10103kB. There are 3 three human enterotypes.
An enterotype is a classification of living organisms based on its bacteriological ecosystem in the gut microbiome. The discovery of three human enterotypes was announced in the April 2011 issue of Nature by Peer Bork and his associates.
Explanation:
Yes, the entropy of the universe is increased by human civilization. but only by a negligibly small amount. The entropy of the cosmos is increased by a one-gram mass entering a supermassive black hole more quickly than the entire Earth's annual energy production.
What is entropy?The quantity of energy that cannot be used to perform work is measured by an object's entropy. The number of alternative arrangements that the atoms in a system can have is also measured by entropy. Entropy is a measure of uncertainty or randomness.
What is the relation between entropy and the human race?
Living things should have substantially lower entropy than their non-living components since life is highly organized. In reality, one of the primary characteristics of life is the use of energy to establish and sustain order. Based on the few observations we have of other worlds, it appears that life is improbable, which is one implication of low entropy for life. However, another implication is that if living things act to raise entropy globally, there must be a corresponding decrease in entropy locally to counteract that rise. This is necessary because of the second law of thermodynamics, which states that a rise in entropy is by far the most statistically likely result.
However, "closed systems," which refers to a system that is unable to exchange heat or energy with its surroundings, are subject to the second law. Heat can be used by an organism that can interact with its environment to reduce local entropy and gain local order. The ability to locally lower entropy is literally a matter of life and death for that creature, even though the overall state of chaos continues to worsen.
Human beings are a clear illustration of this idea. Compared to inanimate objects like air and water, our human bodies have a relatively high degree of order. A human represents far more order even when compared to dirt, which has a diverse ecosystem of microorganisms and larger creatures like worms. However, this is not in conflict with the second law because our ability to consume food and eliminate incredibly disorganized waste products allows us to sustain life. In order to maintain or reduce local entropy levels and hence stay alive, humans can extract the chemical energy from food and consume it.

The main points of the cell theory are:
1. The cell is the SMALLEST living unit of life.
2. The cell is so small is it is not visible to the naked eye.
3. The shape of the cell can vary based on the different lifeforms they are in.
4. The size of the cell also varies.
5. All living organisms or lifeforms are made from cells.
6. Cells originate from a pre-existing cell, in multicellular lifeforms, then the pre-existing cell will divide into many other cells with the process repeating.
7. All cells retain the same properties, such as growth, respiration, and etc.
1) Examine the diagrams below.
2) Describe and explain the changes in the groups of species 2 through 6 in the “Over Time in Six Stages” graph (the top one). Use scientific reasoning to support your explanation.
Answer:
This a process of ecological succession that occurs in every environment.
Explanation:
The first organism which starts growing on the rocky surface are the mosses and grasses. We called it primary succession because mosses and grasses are the first organisms which lives on rocky surface. After some time, these mosses disappear or removed due change occur in the environment and new species such as higher plants start growing on these surface. The mosses die and provide nutrients for the higher plants. We called it secondary succession because the mosses are removed and higher plants takes their place.
Antoine Lavoisier performed his classic twelve-day experiment in 1779 which has become famous in history. First, Lavoisier heated pure mercury in a
swan-necked retort over a charcoal furnace for twelve days. A red oxide of mercury was formed on the surface of the mercury in the retort. When no
more red powder was formed, Lavoisier noticed that about one-fifth of the air had been used up and that the remaining gas did not support life or
burning. Lavoisier called this latter gas azote (Greek 'a' and 'zoe' - without life). He removed the red oxide of mercury carefully and heated it in a
similar retort. He obtained exactly the same volume of gas as disappeared in the last experiment
Lavoisier's experiments use the scientific, method of finding out the nature of an unknown substance by analysis, breaking down, and synthesis, and
then building it up again from its constituents. In his experiments Lavoisier separated air into two constituents: the one which supports life and
combustion, and is one-fifth by volume of air he called oxygen, the other four.fifths which is now called nitrogen. From the two gases he synthesized
something that has the characteristics of air. Lavoisier's experiments gave us the theory of combustion as we have it to this day: that when a substance
burns in air, it combines with oxygen of the air and the product of combustion is heavier than the original substance.
What happens to the second and third stages when they run out of fuel?
Answer:
When the first stage separate, then it will not descend further and it will fall away. It would not be able to launch into air.
The first stage actually help to release it from shell, the first stage of multistage rocket help it to sprout.
If the first stage runs out of the fuel, then there will be no combustion in rocket and it will not ascend further into next stages.
If the second and third stage run out of the fuel then the next 4th and 5th stages will happen to a cessation and there will be a likelihood for it to fall down to earth.

how would you use the scientific method to answer this question: do mice live longer when they are fed high-sugar diets
Answer:
The question: Do mice live longer when they are fed high sugar diets?
Hypothesis: There are two hypothesis the null hypothesis which we assume is correct, it states that a high sugar diet will have no effect on the life span of a mouse and an alternate hypothesis that we accept if evidence shows that sugar does increase the life span if mice. It says a high sugar diet does incerease the life span of mice.
Prediction: Assume that the null hypothesis is correct. High sugar diets will not increase the life span of the mice.
Collect data through experimentation. Use some mice as a 'control'. These mice will not undergo any changes but will be kept for comparison. Expose some other mice to high sugar diets and the compare the outcome with the 'control' mice.
Analyzing: From the experiment this you can choose which hypothesis you are going to accept. I.e. null: no change or alternate: there was a change and do some extra research to back up your hypothesis.

If the adenine in the 15th position of the sequence is changed to a guanine, the person does not have CF. However, if the thymine in the 14th position is changed to a cytosine the person does have CF. What are some reasons this might occur?
Answer:
Explanation:
Mutation is a sudden heritable change in the genome of an organism.
Substitution is a form of mutation whereby a base pair is been substitued for by another base pair resulting in a serious damage.
Codon are three alphabeth coding for a particular amino acid.
When substitution occurs in a base pair and the replacement forms a protein that has the same function as the one that was removed there will be no observable in the phenotype. Hence, If the adenine in the 15th position of the sequence is changed to a guanine, the person may not have cystic fibrosis.
But when a particular base pair is substituted for and an entirely new protein or amino acids results with a different functions and structure it could lead to a serious damage or healthy issue. Hence, If the adenine in the 15th position of the sequence is changed to a guanine, the person does have cystic fibrosis.
