Compare fission and fusion
Answer:
fission and fusion are both nuclear reactions that produce energy, but the applications are not the same.
Fission is the splitting of a heavy, unstable nucleus into two lighter nuclei, and fusion is the process where two light nuclei combine together releasing vast amounts of energy.
CAN SOMEONE HELP ME WITH THIS? YOU HAVE TO Transcribe and translate the following DNA sequences. plz help
To solve this you should know that Adenine(A) pairs with Thymine(T), but in RNA thymine is replaced with Uracil(U) and Guanine(G) pairs with Cytosine(C).
The codon, present in the mRNA represents a group of three letters that is complementary to the DNA strand. The codon is a result of transcription. The anticodon is present in tRNA, the structure that transports amino acids to the protein synthesis site(ribosome) during translation. The anticodon is complementary to the codon.
It's pretty easy to interpret the codon table as the first, second and third letters are indicated.

DNA binding proteins in prokaryotes regulate gene expression by controlling transcription
true or false
Answer:
True
Explanation:
Gene expression, which involves the transcription of DNA into mRNA and the subsequent translation of mRNA into proteins, is regulated in the cell of prokaryotes i.e. it is kept under control. This regulatory process, however, is done at the TRANSCRIPTIONAL LEVEL, in prokaryotic organisms like bacteria.
DNA binding proteins called transcription factors bind to the promoter region of a gene and either facilitates/enhance the binding of RNA polymerase or inhibits its binding. The enhancers are called ACTIVATORS while the inhibitors are called REPRESSORS.
What technique did Hershey and Chase use in their experiment that led to the conclusion that DNA, not protein, was the genetic material in viruses?
Answer:
They used radioactive labeling techniques to build two different types of phage.
Explanation:
In 1952, a set of experiments were carried out by American biochemists Alfred D. Hershey (1908-1997) and Martha Chase. They prepared two separate virus samples, one contained DNA labeled with a radioactive isotope and the other contained protein labeled with a different radioactive isotope. They grew the two types of viruses separately, infected bacteria with the two sets of phages and analyzed the bacteria for radioactivity. From the results obtained, Hershey and Chase concluded that the viral genetic material was DNA and not protein, reinforcing the observations previously made by Avery.
In dogs, there is a hereditary type of deafness caused by a recessive gene. Two
heterozygous dogs mated, they both carry the gene for deafness but have normal hearing. Using the Punnett Square below, answer the following questions.
1. What are the possible genotypes? Select all that apply based on the Punnett Square above. *
DD
Dd
dd
2. What is the genotype for offspring #2?*
DD
Dd
dd
Answer:
All of the genotypes for question one are possible. for question 2, the genotype of offspring 2 is Dd.
Explanation:
The chart shows that there can be a combination of genes DD, Dd, and dd (D being the dominant trait, d the recessive). there's a one in four chance of blindness for the dog. by reading the rows and columns of the chart, you can determine which genes the dog will have.
1.Since both of the parents are heterozygous the offspring can have all three genotype possiblities: DD Dd and dd
2.The genotype of offspring is the combination of the alleles D and d:Dd

Explanation:
why do the antibody numbers remain higher after the first infection than before it?
Explanation:
During a primary infection levels of antibodies slowly increase, peak at around ten days and then gradually decrease. ... The antibodies are produced so quickly by the memory cells that the pathogen is killed off before it can make the person ill.

Answer:
Similarities of Mitosis and Meiosis :))
Explanation:
Mitosis and meiosis have different purposes, but share common features in how they work.
Easy Answer:
-Both can divide (option 1)
-Same number of chromosomes as the original cell (option 4)
-Both have the basic 5 phases
Multiple Stages
Both mitosis and meiosis are multistage processes. The stages are interphase, prophase, metaphase, anaphase and telophase. The same general processes occur in each of these stages for mitosis and meiosis. Interphase is cell growth and DNA replication in preparation for cell division. Prophase is when the nuclear membrane degrades. Metaphase is when the chromosomes align in the middle of the cell. Anaphase is when the chromosomes are pulled apart. Lastly, telophase is when one cell splits into two separate cells.
DNA Replication
Mitosis and meiosis both involve duplication of a cell’s DNA content. Each strand of DNA, or chromosome, is replicated and remains joined, resulting in two sister chromatids for each chromosome. A common goal of mitosis and meiosis is to split the nucleus and its DNA content between two daughter cells. Before DNA can be separated between two cells, it must be duplicated and then condensed into a form that can be efficiently transported. The condensed form of DNA is called chromosomes. Chromosomes can be physically pulled apart, and make separating long strands of DNA easier for the cell because the DNA strands become like a tightly wrapped yarn ball.

How do H-R diagrams help scientists compare new stars with the Sun? In your answer, name one type of data that H-R diagrams do not show.
Answer: Hertzsprung-Russell (HR) diagram is an essential tool used in stellar evolution. In the universe, there are several hundreds of billions of stars. Scientists use the tool, in differentiation, the billions of stars in the world from the sun. In the HR tool, there plotting of the luminosity or energy output of a star, which is plotted on the X-axis of a graph against the absolute magnitude. The sun's magnitude is an absolute of +48, which, when plotted against its luminosity, helps in setting an apparent variance between the sun and any other star. Additionally, the sun has been identified as the primary star with a very high temperature. Hence the tool can locate the sun from other forms of stars. HR diagrams outline data such as temperature and luminosity or energy. However, star distance from the Erath is not a type of data represented in the charts.

Many pine trees grow in the taiga, the largest habitat in the world. Using incredible sources such as nasa research the typical climate conditions in the taiga. Explain why the structure of pine cones helps ensure successful reproduction in the taiga
Answer:
Hard structure of cones protects reproductive parts of pine trees.
Explanation:
The structure of pine cones helps in successful reproduction in the taiga because in pine trees both male and female reproductive parts are present on the same tree that leads to successful reproduction and production of seeds. The pollen from the male cone fall onto the female cone that produces seeds after fertilization process. The structure of cones are hard that protects the male and female reproductive part in that environment.

Describe three interactions that red wolves might have with other living things.
Answer:
By scent-marking, body language, and a series of vocalizations, red wolves interact. These contain, along with a series of barks, growls, and yaps, the distinctive howl. The howl of the red wolf is somewhat similar to that of a coyote, but is mostly pitched deeper and lasts longer.
Red wolves communicate with one another through vocalizations, body language, and scent-marking. The unique howl may be heard in these, along with a variety of barks, growls, and yaps.
What best define red wolves interactions?Until they become accustomed to people, wolves typically avoid engaging with them.
In general, red wolves create enduring pair connections with one another. There are still more than half of red wolves in captivity. Red wolves live an average of eight to nine years in the wild.
Please make a donation to protect wolves where they belong—in the wild. Fend off the wolves. Although wolves are apprehensive of people, they can lose that fear by becoming accustomed to them.
The howl of the red wolf resembles that of the coyote in some ways, but it is often deeper and lasts longer.
Therefore, red wolves communicate by scent-marking, vocalizations, body language.

What piece of evidence supports the viral model presented in Viewpoint #2 that viruses are non-living?
Answer:
b. viruses do not undergo mitosis
Explanation:
One characteristics of non-living things is their ability to reproduce. Viruses on their own lack this ability to reproduce their kind. Mitosis is a form of reproduction where one cell divides to form two daughter cells. Viruses do not undergo mitosis.
Viruses are just an assembly of biochemical particles that need to gain entrance into a living cell to be able to multiply.
