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.

Which RNA strand below is transcribed
from DNA to carry a message?
tRNA
mRNA
rRNA
Answer:
mRNA (messenger RNA)
Explanation:
Answer:
mRNA........................
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.

Explanation:
A one-year simulation is run with the settings shown below. The resulting yield was 6.6 tons per hectare, or 44% of the maximum yield. What is the most likely cause for the poor yield?
Answer: The corn plants were damaged by the herbicide.
Explanation
Depending upon the plant affected and the herbicide used, effects of herbicide damage differ. Popular signs include flattened stems or twisting or corkscrewing. Leaves can have shapes, sizes or textures that are irregular. Moreover, yellow or reddened leaves or leaf veins may. This usually leads to loss in crops as noticed from the maize plantation where more than half was lost.
The most plausible explanation of the low yield would be herbicide harm to the maize plants.
Herbicide
Herbicide damage has different consequences it depends on the plant as well as the herbicide employed. Ground down stems, twirling as well as rotating clockwise are popular symptoms.
Leaves could have varied forms, dimensions, and properties. Furthermore, yellow or reddish leaves especially leaf veins are possible. This frequently results in crop losses, as seen in the maize plantations, where more than half of the harvest was destroyed.
Thus the response above is correct.

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.

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.

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.
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.

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.

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.

Proteins are made of genes and code for DNA.
2.
Genes are made of proteins that code for nitrogen bases.
3.
DNA is made of carbohydrates that code for genes.
4.
Genes are made of DNA and code for proteins.
Answer:
An accurate description of genes is that genes are made of DNA and code for proteins.
Explanation:
Genes are the molecules responsible for containing the genetic information that determines specific characteristics or features of an individual. Genes are housed in chromosomes, in specific locations called locus.
A DNA molecule forms a chromosome, and fragments of that same molecule form the genes on that chromosome. The information contained in each gene codes the synthesis of proteins, as well as the synthesis of RNA.
The other options are not correct because:
1. Proteins are not made of genes, but of amino acids, and they do not code for DNA.
2. Genes are not made of proteins, but of DNA fragments.
3. DNA is not made of carbohydrates.
Answer:
Genes are made of proteins that code for nitrogen bases.
