Answer:
Allele frequencies
Explanation:
The only component that is transmitted from generation to generation is the genetic material (genes), the fact that an individual leaves more descendants implies that their genetic variants (alleles) will be more represented in the next generation. The frequencies of the different alleles will change from one generation to another, and this change will be irreversible when the set of genes in the population is considered, since it is highly unlikely that a previous configuration will be returned in all gene variants. Hence, from a population point of view, evolution is ultimately a cumulative and irreversible change in the proportions of different gene variants in populations. The agents that change the allele (or gene) frequencies of populations, that is, factors of evolution, are mutation, genetic drift, migration, and natural selection. Mutation is a factor that increases genetic diversity. Natural selection is the process by which the gene frequencies involved with certain traits vary from generation to generation, since some variants of the trait have a greater capacity than others to survive and produce offspring. The mutation rate of a gene or DNA sequence is the frequency at which new mutations occur in that gene or sequence in each generation. In each generation there is a gene raffle during the transmission of gametes from parents to children which is known as genetic drift. In the absence of gene flow, gene drift will also lead to local differences in allele frequencies.
What is the end result of transcription?
an amino acid chain (protein)
messenger RNA (mRNA)
complementary DNA
Okazaki fragments
Put the following molecules in order of the correct sequence they are made in protein synthesis.
Reorder answers
RNA
Protein
Gene
Answer: 1. messenger RNA (mRNA). 2. rna, gene, protein. brainliest?
Explanation:
The end result of transcription is mRNA, and the correct sequence of molecules in protein synthesis is Gene → Transcription (RNA) → mRNA → Protein.
Transcription is the process in which a segment of DNA is used as a template to synthesize a complementary mRNA molecule. It occurs in the nucleus of eukaryotic cells and in the cytoplasm of prokaryotic cells. During transcription, the DNA molecule unwinds, and an enzyme called RNA polymerase binds to a specific region of the DNA known as the promoter. The RNA polymerase then moves along the DNA strand, synthesizing a complementary mRNA molecule using the base pairing rules (A with U, G with C).
The end result of transcription is the production of mRNA. mRNA is a single-stranded molecule that carries the genetic information from the DNA to the ribosomes in the cytoplasm. It serves as a template for translation, where the information encoded in the mRNA is used to synthesize proteins.
Regarding the sequence of molecules in protein synthesis, the correct order is as follows:
Gene: A gene is a specific sequence of DNA that contains the instructions for making a protein. It serves as the starting point for protein synthesis.Transcription (RNA): Transcription is the process in which an mRNA molecule is synthesized from a DNA template. This step occurs in the nucleus.mRNA: The mRNA molecule carries the genetic information from the gene to the ribosomes. It serves as the template for protein synthesis.Protein: Protein synthesis occurs during translation, where the mRNA is read by ribosomes, and amino acids are assembled in the correct order to form a protein.Therefore, the correct sequence of molecules in protein synthesis is Gene → Transcription (RNA) → mRNA → Protein.

Is the following sentence true or false? During meiosis, the two alleles for each gene stay together.
Answer:
False
Explanation:
During meiosis, a cell goes from a diploid stage to a haploid stage. So no, the alleles do not stay together.
The Meiosisi is basically a process by which the number of chromosomes is reduced by half to form a sex cell.
A student is observing an image of an object that could be a comet, meteoroid or asteroid. Which of the following questions
would BEST confirm that the object is a comet?
A. Does the object contain ice?
B. Does the object contain metals?
C. Where is the object found?
D. How big is the object?
Answer:
A does the object contain ice
Explanation:
The BEST question that would confirm that the object is a comet is "Does the object contain ice?" Hence the correct option is A.
What are comets?Comets are small, icy celestial bodies that originate from the Kuiper Belt and the Oort Cloud. As they approach the Sun, they heat up and release gas and dust in the form of a coma and a tail, which can be observed from Earth. Therefore, if the object contains ice, it is most likely a comet.
Meteoroids, on the other hand, are smaller rocks that travel through space, and asteroids are larger rocks that orbit the Sun between Mars and Jupiter. Neither meteoroids nor asteroids typically contain ice.
As for the other options, whether the object contains metals or how big it is does not provide enough information to determine whether it is a comet, asteroid, or meteoroid. And while the location of the object may provide some clues about its origin, it is not a definitive factor in determining whether it is a comet.

Clouds water cycle pls tell me :)
Answer:
Clouds exist in the atmosphere because of rising air. As air rises and cools the water in it can "condense out", forming clouds. Since clouds drift over the landscape, they are one of the ways that water moves geographically around the globe in the water cycle.

what is the difference between an alligator and a crocodile
Snout Shape: Alligators have a wide, rounded, u-shaped snout, while crocodiles have long, pointed, v-shaped snouts. ... Crocodiles are different from alligators in this sense, where both upper and lower jaws of a crocodile are the same size, exposing their teeth as they interlock, creating the look of a toothy grin.
Alligators have U-shaped faces that are wide and short, while crocodiles have thin V-shaped muzzles. When an alligator closes its mouth, you tend to see only its upper teeth. Crocodiles on the other hand flash a toothy grin with their top and bottom teeth interlacing.

Answer:
A
Explanation:
Almost all embryos of vertabrites look the same at early embryo stages, even humans to other organisms. This is because they all have a common ancestory, adn orginated from a organism with an embryo that looked like this.
It is clear it cannot be the other answers for the folowing reasons:
The organisms will definatly not look the same, considering they are birds and reptiles. The 2nd answer speaking of geography isnt very accurate, and cannot be determined because as I said above, any vertibrate embro looks very similar, and close geopgraphy isnt what made them look similar.
Again, all vertabrites have the same embryos, and that is a phylum. Not a genus. There are many genus in a phylum, and the ecaxt one cannot be determines.
As I said above, HUMANS look simiar to BIRDS and REPTILES, but clearly grow to be much different.
Answer:
A: the organisms share a common ancestory
