Explain how the characteristics of the two types of fish relate to the genetic diversity of the species. (for context they're speaking about the Mexican tetra, the surface one and the blind cave one
Answers
Answer:
So, there are 3 parts that explain the answer to your question.
Explanation:
Part A-
The surface fish live near the surface of the water, and the blind cave fish live in dark subterranean caves. The surface fish have eyes and pigmentation on their bodies. The blind cave fish don’t have eyes, and they’re often albinos.
Part B-
The two fish are of the same species because they can mate with each other. Also, the characteristics of the blind cave fish enable them to live in caves. Eyes need energy. So, developing bodies with no eyes allowed these fish to function more efficiently.
Part C-
The two types of fish developed different traits within their respective habitats. However, as a species, they have some genetic diversity because these populations have different genes between them.

3. What is the difference between finite and infinite?
4. How does using a fan lowers the greenhouse gas emissions?
5. What is mitigating?
6. How can sweeping minimizes noise pollution?
7. How does planting can conserve our natural resources?
Answers
Answer:
Explanation:
1) Hanging clothes to dry reduces electricity use and greenhouse gas emissions and makes clothes last longer.
2) The carbon footprint serves as an indicator to compare the amount of greenhouse gases emitted over the entire life cycle from the production of a good or service along the supply chain to its final consumption
3) The word 'Finite' itself describes that it is countable, and the word 'Infinite' means it is not finite or uncountable.
Answer:
Explanation:
1.) Using hanging clothes instead of using any machine(dryer) reduces the emission of gases and uses natural ways (sunlight, wind) to dry them up.
2.) Carbon footprint can be defined as the amount of greenhouse gases especially carbon dioxide (CO2) and methane emissions, that relate to daily human activities.
3.) If the no. of elements are countable then they are said to be finite, while if the no. of elements are uncountable then they are said to be infinite.
4.) Fans help to evaporate moisture from the skin, providing a cooling effect as it creates breezes instead of cooling it, while
Air conditioners remove heat from the air by using energy-intensive refrigeration cycles,
Thus fan helps to reduce greenhouse gas emissions.
5.) Mitigating refers to the act of reducing or minimizing the negative impacts of a particular issue or problem.
In 4 or more complete sentences, describe the process of protein synthesis and explain how transcription and translation creates protein
Answers
Protein synthesis occurs in the cell and is divided into 2 stages, namely transcription and translation. The process of transcription occurs in the cell nucleus by copying the genetic code in DNA and forming mRNA strands which are duplicates of DNA.
The RNA strands that are formed will come out of the cell nucleus and then undergo a translation process that occurs in the cytoplasm. With the help of ribosomes, the amino acids will line up according to the sequence of the genetic code in the mRNA to form polypeptide chains that make up the protein structure.
What is protein synthesis?
Protein synthesis is the formation of proteins in the human body and occurs in the smallest units, namely cells. Protein synthesis is divided into 2 stages, in the following order:
1. Transcription
Transcription is the process of copying the genetic code or DNA that occurs in the cell nucleus or nucleus. The process of copying the genetic code is carried out by unbinding the DNA with the help of RNA polymerase, then forming a copy of the genetic code that is complementary to the sequence of hydrogen bases in the DNA. The process of transcription produces a strand of genetic code called mRNA or RNAd.2. Translation
Translation is the process of translating the genetic code contained in the mRNA and occurs in the cytoplasm. With the help of the ribosome, the mRNA will be translated and the amino acids will move towards the ribosome. Amino acids will form a sequence that is complementary to the mRNA so that a polypeptide strand that makes up the protein molecule is formed.Learn more about Protein synthesis at https://brainly.com/question/15404950
#SPJ1
1. Transcription:
Transcription is the first step in protein synthesis and takes place in the nucleus of eukaryotic cells or in the cytoplasm of prokaryotic cells. It involves the conversion of genetic information from DNA into a complementary RNA molecule. Here's how it works:
a. DNA unwinding: An enzyme called RNA polymerase binds to a specific region of the DNA molecule known as the promoter. The DNA molecule unwinds at this site.
b. Complementary RNA synthesis: RNA polymerase reads the DNA template strand and synthesizes a complementary RNA molecule, using adenine (A), cytosine (C), guanine (G), and uracil (U) as the RNA bases, instead of thymine (T). This newly formed RNA molecule is called messenger RNA (mRNA).
2. Translation:
Translation is the second step in protein synthesis and occurs in the cytoplasm, specifically at the ribosomes. It involves the conversion of the mRNA molecule into a functional protein. Here's how it works:
a. Initiation: The ribosome attaches to the mRNA molecule at a specific start codon (usually AUG), signaling the beginning of translation.
b. Elongation: Transfer RNA (tRNA) molecules bring amino acids to the ribosome, guided by the mRNA codons. These tRNA molecules have anticodons that complement the mRNA codons.
c. Peptide bond formation: As the ribosome moves along the mRNA molecule, it catalyzes the formation of peptide bonds between the amino acids carried by tRNA molecules. This forms a growing polypeptide chain.
d. Termination: Translation continues until a stop codon (UAA, UAG, or UGA) is encountered on the mRNA. At this point, a release factor binds to the ribosome, leading to the release of the completed polypeptide chain.
In summary, protein synthesis begins with transcription, where DNA is transcribed into mRNA. Then, during translation, the mRNA is decoded by ribosomes, and amino acids are linked together to form a polypeptide chain, which eventually folds into a functional protein. This intricate process ensures that the genetic information encoded in DNA is faithfully converted into the proteins that carry out essential functions within cells and organisms.

A pedigree chart is used to _______.
predict percentage of offspring with a trait
predict genotypic probabilities
track inherited traits through generations
identify the genotype of parents
Answers
A pedigree chart is used to track inherited traits through generations.
A pedigree chart is a visual tool that represents the inheritance patterns of specific traits or genetic conditions within a family. It helps to trace the occurrence of traits, diseases, or genetic conditions across multiple generations by depicting the relationships between individuals and their affected or unaffected status.
Pedigree charts are commonly used in genetics and genetic counseling to analyze patterns of inheritance, identify carriers of genetic disorders, determine the probability of passing on certain traits or diseases, and study the transmission of traits within families. By examining the patterns of inheritance in a pedigree chart, one can gain insights into the mode of inheritance, such as autosomal dominant, autosomal recessive, or X-linked inheritance, and make predictions about the likelihood of certain traits or conditions appearing in future generations.
When an offspring receives one green allele (G) and one red allele (R), the result id a green leaf with red veins
Answers
Answer:
GR
Explanation:
the genotypes of the parents are homozygous dominant GG and RR so when they fertilise they give all GR offsprings
The genotype of the plant is GR. This is because the offspring received green allele (G) as well as red allele (R), and both results showed up as the plant is green with red veins.
When something gives up alleles to its offspring, the parents originally have alleles like Aa and Bb. When offspring is created, you can use the Punnett square to guess which alleles will be passed on. In the plant’s case, G and R were passed on.

Use the concept of natural selection to explain how a population of moths might evolve if only a few members can blend in with their environment.
Answers
Answer:
A great example is the peppered moths evolution. Since the Industrial Revolution the birch trees started to turn black from the soot. This casued all the white moths to be eaten from birds. The ones that were left to mate were black moths which favored the black gene. So overtime black moths became more common. They were naturaly selected based on color to survived and pass down their black colored genes.
Explanation:
A population of moths might evolve if only a few members can blend in with their environment, and those who cannot blend in would be chosen by the predator. Through natural selection, the blended population will grow.
What is natural selection?
Natural selection is the force that selects the organism in the ecosystem that can fit best in the environment. In the case of the peppered moth, the light-colored moth was earlier camouflaged with the light color of the bark, so the dark moths were chosen by the predator. Later, after industrialization, the bark became black from pollution, allowing light moths to be seen and eaten by the predator, demonstrating how natural selection varies depending on environmental conditions.
Hence, the population of moths might evolve if only a few members can blend in with their environment, and those who cannot blend in would be chosen by the predator. Through natural selection, the blended population will grow.

Explanation:
5),[5] better known by his stage name Chief Keef, is an American rapper. Cozart's music first became popular during his teen years in the early 2010s among high school students from Chicago's South Side.[6] In 2012, his popular local single "I Don't Like" was remixed by American rapper Kanye West and reached the Billboard Rap Top 20, further raising Cozart's profile.[6] A bidding war between major labels resulted in Keef signing with Interscope. His debut album Finally Rich was released in December 2012, and featured the singles "I Don't Like" and "Love Sosa", which would popularize the Chicago rap subgenre drill.[7]
Chief Keef has faced ongoing legal issues during his career, including weapons possession charges, house arrest sentences, and a performance ban imposed by Chicago authorities.[8] Though he was dropped from Interscope in late 2014 and later signed to 1017 Records, he continued self-releasing projects through his own Glo Gang label. These included: Nobody (2014), Back from the Dead 2 (2014), Bang 3 (2015), and Th0t Breaker (2017).
By the late 2010s, critics have pointed to Chief Keef as a major influence on contemporary hip hop through his innovation with the drill subgenre and the impact of his music on other artists.[9][7][10]
