identify the advantages and disadvantages for both fossil fuels and nuclear fuels
Fossil Fuels
Advantages: Large amounts of fairly cheap electricity can be generated in one place. Transporting it to power stations and plants is easy. Easy to find.
Disadvantages: Major pollution, the plants that use fossil fuels let out lots of carbon dioxide, which contributes to the greenhouse effect. They also produce sulfur dioxide, a gas that contributes to acid rain. Mining coal can be very dangerous. Coal power plants require lots of coal to run.
Nuclear Fuels
Advantages: No greenhouse gases. The energy obtained in these plants is 10 million times more powerful than the same amount made in a coal plant. This type of energy is also reliable and rarely shuts down due to outside causes.
Disadvantages: Very harmful waste. Supplies will run out in years to come. It takes days to shut down a plant. Meltdowns expose very large amounts of radioactivity in an area.
Answer:
Alright so:
Explanation:
Advantages of fossil fuels: cheap, easy access, give a ton of concentrated energy, easier to transport from place to place, very stable and very reliable.
advantages of nuclear fuels: they are also cheap, also easy to get access, are cleaner, are safer, and less pollution.
Disadvantages of fossil fuels: they contribute to global warming, lots of pollution, dirty, extremely dangerous if an accident is made, the process of drilling for fossil fuels is also very dangerous and it is nonrenewable.
Disadvantages of nuclear fuels: radioactive waste, pollute the environment as well, dangerous if accidents happen, nonrenewable, expensive, limited supply, and it takes a long time before it can be transported.
DNA codes for _______ which determines ________
(a) proteins, peptide bonds
(b) mRNA, tRNA
(c) mRNA, ribosome
(d) protein s, traits
DNA carries genetic information in nucleotidic sequences. This information is translated into proteins that codes for traits. Option D. Proteins - Traits.
What DNA codes for?DNA molecules carry genetic information stored in their nucleotidic sequences. This molecule has information about the whole organism and its functions.
Through protein synthesis, this information is first transcripted into mRNA molecule and then translated into proteins.
mRNA is in charge of taking only sequences that code for a single protein from the nucleus to the cytoplasm, where rRNA and tRNA will build the protein.
What are proteins and what is their function?
Proteins are complex macromolecules formed by a sequence of amino acids. They carry out several functions in the organisms.
They are in charge of most cellular activities and are necessary for the structure, function, and regulation of tissues and organs.
Proteins are in charge of determining traits or features that will be expressed by the individual through its development.
The correct option is D. DNA codes for _proteins_ which determines _traits_.

https://brainly.com/question/7575381
Final answer:
DNA codes for proteins which in turn determine traits, with the sequence of amino acids in a protein being critical to its function. The process involves transcription and translation with mRNA and tRNA playing key roles.
Explanation:
DNA codes for proteins which determines traits. The process begins with transcription, where DNA's nucleotide sequence is copied into messenger RNA (mRNA). This mRNA then provides the code for the sequence of amino acids in a protein during translation. Proteins are comprised of long chains of amino acids linked together by peptide bonds. The specific sequence of amino acids in a protein dictates its structure and function. Transfer RNA (tRNA) carries amino acids to the ribosome, where they are added to the growing protein chain as dictated by the mRNA sequence.
The correct answer to the question is therefore (d) proteins, traits. Proteins are responsible for carrying out a vast array of functions in cells and organisms, and the traits of an organism can be influenced by the types and functions of the proteins produced as a result of gene expression.
Two spotted leopards produce a litter of four cubs. Three of the cubs are spotted and one is solid black. The black coat is probably what type of trait? *
Two spotted leopards produce a litter of four cubs. Three of the cubs are spotted and one is solid black. The black coat is Recessive Trait
Explanation:
A recessive trait is a trait that have been expressed when an organism has two recessive alleles or two forms of a gene.
Traits are called the physical/non-physical characteristics of a organisms that can or cannot be observed.
Physical characteristics like hair, eye color can be observed while other characteristics like the shape of blood cells cannot be observed.
It is important to note that if the trait is dominant, one of the parents will have the trait. Dominant traits does not skip a generation. In case the trait is recessive, neither of the parent will have the trait .Recessive trait can skip a generation
So we can say that in the case mentioned in the question
Two spotted leopards produce a litter of four cubs. Three of the cubs are spotted and one is solid black. The black coat is Recessive Trait
Final answer:
In a litter of four cubs where three are spotted and one is solid black, the solid black coat is likely a recessive trait, since the spotted pattern is exhibited by the majority and is thus the dominant trait.
Explanation:
The question addresses a scenario where two spotted leopards produce a litter of four cubs, three of which are spotted, and one is solid black. Since the majority of the cubs are spotted, this suggests that the spotted pattern is the dominant trait. The solid black coat in one cub is therefore likely to be a recessive trait. In genetics, a dominant trait is one that is expressed in the phenotype even if only one copy of the allele for that trait is present (heterozygous). On the other hand, a recessive trait requires two copies of the allele (homozygous recessive) to be expressed.
Given the context, and consistent with information about cat coat genetics, the solid black color exhibited by the single cub can follow principles of incomplete dominance, co-dominance, or be influenced by multiple genes or loci, which is a more complex topic involving epistatic interactions. The most straightforward answer is that the black coat is a recessive trait when considering the simple Mendelian inheritance patterns observed in the litter.

delivered a healthy baby boy at Metropolitan General Hospital. At 1:20 pm the hospital's
fire alarm sounded. Nurses and orderlies scrambled to evacuate patients and the three
babies were rushed to safety. After the danger had passed, the hospital staff was distressed
to find that in the confusion, they had forgotten which baby was which! Since the babies
were rescued before receiving their identification bracelets, there was no easy way to
identify them. Dr. Robinson, head of pediatrics, ordered that DNA profiles be preformed

To determine which baby belongs to which parents in the hospital mix-up scenario, DNA fingerprints of the babies and their parents are compared to find genetic markers that confirm biological relationships. The child must share DNA markers with both parents, and the DNA analysis is used to match these genetic profiles.
Explanation:The question revolves around a scenario where three children were delivered at the same time in a hospital, and due to an emergency, their identities got mixed up. To determine which baby belongs to which parents, DNA profiles of the babies and their parents were compared to establish biological relationships based on genetic markers. By examining the DNA fingerprints of the babies and comparing them to those of the parents, the child's parents can be ascertained. The child must share genetic markers with its parents, as children inherit half of their DNA from the mother and half from the father. During a DNA analysis, specific regions of the DNA are analyzed to detect similarities that are unique to family members.
When dealing with paternity or maternity testing, a match in these genetic markers must be found between the child and the alleged parents to confirm a biological relationship. Modern forensic science often uses this approach to resolve cases of uncertain paternity or identify individuals in scenarios like the hospital mix-up described. DNA analysis is a powerful tool in maternity and paternity testing, used not only for medical and legal cases but also for research purposes.
Some people have one sickle cell gene and one normal gene. They have few defective cells and no symptoms because the sickle cell gene is recessive. How does the human system of reproduction result in people getting one copy of a sickle cell gene and one copy of a normal gene? Describe the process.
Answer:
Explanation:During fertilization the embryo receives half of its genetic information from both parents. If one parent is a carrier or sickle cell their genes would be Aa little a being the recessive gene. When mixed with the other parents gene who does not have sickle cell their genes would be AA. When you make a pun net square the results would be AA,AA,Aa,and Aa. Therefore the offspring would have a 50% chance of being a carrier of sickle cell but not having the actual disease
Asexual reproduction involves...
A) two parents and results in offspring that are different from both parents.
B) only one parent and results in offspring that are very different from the parent.
C)only one parent and results in offspring that are identical to the parent.
D)two parents and results in offspring that are identical to one parent.
Answer:
c
Explanation:
C)only one parent and results in offspring that are identical to the parent.
Final answer:
Asexual reproduction involves a single parent and produces offspring that are genetically identical to the parent, through processes like binary fission.
Explanation:
Asexual reproduction involves a single parent. It results in offspring that are genetically identical to each other and to the parent. This form of reproduction can occur in various organisms, including all prokaryotes and some eukaryotes. Different methods of asexual reproduction include binary fission, fragmentation, and budding, with binary fission being a process where a parent cell splits into two identical daughter cells.
Therefore, the answer to the student's question is C) only one parent and results in offspring that are identical to the parent.
