Transcription is A. The process of making RNA from DNA. B. The activation of a gene that produces proteins. C. Irreversible changes to the DNA sequence. D. The process of making proteins from RNA
Answer: A. The process of making RNA from DNA.
Explanation:
The transcription can be defined as the process of transfer of genetic information from DNA or deoxyribonucleic acid into messenger RNA. For this double strands of DNA are separated and each strand act as a template strand for the synthesis of mRNA. The transcriptions is initiated by the enzyme RNA polymerase. The enzyme RNA polymerase utilizes DNA for synthesizing the matching complementary bases. The mRNA molecule get elongated and serves as a blueprint for the synthesis of protein in translation.

Explanation:
Show are meiosis and mitosis different
Answer:
The purpose of mitosis is the creation of diploid somatic cells and the purpose of meiosis is the creation of haploid sex cells.
Explanation:
Mitosis takes place in somatic, or body cells, and meiosis takes place in gametes, or sex cells. The purpose of mitosis is growth and repair, while the purpose of meiosis is creating gametes with half the normal number of chromosomes and is for reproduction. Mitosis goes through Interphase, Prophase, Prometaphase, Metaphase, Anaphase, Telophase, and Cyokinesis once to produce two genetically identical diploid somatic daughter cells. Meiosis goes though that twice (Meiosis I and Meiosis II) to produce 4 genetically unique haploid gametes. It has stages (Prophase, Metaphase, Anaphase, and Telophase) such as Prophase I and Prophase II because meiosis occurs twice. Another difference is that mitosis happens throughout your life and meiosis occurs before females are born and throughout a males life.
Contrast the terms “parasitism” and “mutualism” in a sentence
Answer:
Explanation:
Mutualism is the interaction between two or more organisms where both organisms can benefit from the interaction while Parasitism is the interaction between two species where only one benefits from the other organism and the other is harmed in return
Answer:
When both the partners or organisms get benefits from one another by living together is known mutualism. When only one partner or organism gets benefits without any effect on the other is commensalism. When one partner or organism gets benefits while the other is harmed is known as parasitism.

5. You cross one black (Bb) mouse with one brown (bb) mouse. Complete the Punnett square to find the expected ratio of black to brown mice pups. All six mice pups in the litter have brown fur. Explain this result.
I think all the mice had brown fur due to epistasis
Explanation:
The expected results would be 50% black and 50% brown and the ratio could be 2:2. But, if epistasis occurred and the brown fur gene overshadowed the black fur gene, then all the offspring could have brown fur.
The Punnett square to find the expected ratio of black to brown mice pups is to be considered when all the mice had brown fur because to epistasis.
Completion of the Punnett square:The expected result should be 50% black and 50% brown and the ratio should be considered as the 2:2.
In the case when epistasis should be arisen and brown fur gene should be overshadowed the black.
Hence, the same should be considered.

why is important to use an organism with a recessive phenotype in a cross with an organism of unknown Genotype
Answer:
One of the central conclusions Mendel reached after studying and breeding multiple generations of pea plants was the idea that "[you cannot] draw from the external resemblances [any] conclusions as to [the plants'] internal nature." Today, scientists use the word "phenotype" to refer to what Mendel termed an organism's "external resemblance," and the word "genotype" to refer to what Mendel termed an organism's "internal nature." Thus, to restate Mendel's conclusion in modern terms, an organism's genotype cannot be inferred by simply observing its phenotype. Indeed, Mendel's experiments revealed that phenotypes could be hidden in one generation, only to reemerge in subsequent generations. Mendel thus wondered how organisms preserved the "elementen" (or hereditary material) associated with these traits in the intervening generation, when the traits were hidden from view.
It is important to use an organism with a recessive phenotype in a cross with an organism of an unknown genotype to identify the recessive traits.
What are phenotype and genotype?The observable traits of an individual are the result of gene expression; the clinical manifestation of a person with a certain genotype is called the phenotype of an individual. Some examples of the phenotype are height, skin color, eye color, hair nature, etc.
The term "genotype" refers to an organism's whole gene pool, or, in other words, the genetic makeup of that creature. The phrase can also be used to describe the alleles, or different forms of a gene, that an organism carries in a more specific meaning.
A recessive phenotype is used in a cross with an organism of unknown Genotype to identify the recessive traits.

Explanation:
Why did Mendel study pea plants?
Answer:
Pea plants were fundamental in allowing him to understand the means by which traits are inherited between parent and offspring. He chose pea plants because they were easy to grow and could be bred rapidly and had many several observable characteristics like petal color and pea color. Mendel used a tall plant and a small plant expecting a medium plant to com out. That was not the case one tall plant came out and so did 3 small ones. This is because of genetics. And the genetic chart showing what the percents are.

Answer:
A. a phylogenetic tree. it says that i need 20 more characters to enter so this is me wasting them. but the answer is A
The given diagram basically represents a cladogram. The correct option is D.
What is cladogram?A cladogram is a type of diagram that depicts the evolutionary relationships between organisms.
It is a branching diagram in which the nodes represent the descendants' most recent common ancestor. The cladogram is based on the organisms' shared characteristics or traits.
These characteristics, which can be physical or genetic in nature, are used to classify organisms into clades.
Clades are groups of organisms that share a common ancestor, and they are represented on the cladogram as branches.
The organisms are more closely related the closer the branches are to each other. Cladograms are commonly used in biology to study organisms' evolutionary histories.
Thus, the correct option is D.

2. How do gene splicing and gene therapy differ? How are they alike?
Gene therapy and gene splicing are separate but linked processes. A new organism can be created by cutting and recombining genetic material from two separate sources, a process known as gene splicing.
What is gene splicing ?It is a technique that scientists utilise in the lab to develop new organisms with desired features. On the other side, a healthy gene is introduced into the patient's cells during a medical process called gene therapy to treat diseases and disorders.
Gene splicing and gene therapy share certain similarities despite their distinctions. Both procedures entail the modification of genetic material, frequently derived from several sources, in order to produce the desired outcome.
The goal of gene splicing is the development of a new creature or its modification.that of an active organism. Treatment of a disease or disorder is the intended outcome of gene therapy. Both procedures also entail the manipulation of genetic material using specialised methods, such as recombinant DNA technology. Finally, for both methods to be effective, a good understanding of genetics is necessary.

Gel electrophoresis is a technique used to separate DNA fragments according to their size.
DNA samples are loaded into wells (indentations) at one end of a gel, and an electric current is applied to pull them through the gel.
DNA fragments are negatively charged, so they move towards the positive electrode. Because all DNA fragments have the same amount of charge per mass, small fragments move through the gel faster than large ones.
When a gel is stained with a DNA-binding dye, the DNA fragments can be seen as bands, each representing a group of same-sized DNA fragments.

Which experiment could the scientists use that would best determine if these tiny structures are spores?
Answer:
The experiment that scientists could use that would best determine if the tiny structures are spores is called Opto-Electronic Imaging and Imaging Processing.
Explanation:
Optoelectronics speaks to the body of knowledge and of electronic devices that source, detect and control light and how they are used or applied. It is founded on the quantum mechanical effects of light on electronic materials.
Besides Optoelectronic Imaging, there are several other techniques that can be used to identify spores. Some of them are:
1. The culture-based methods: These methods involve the growing of spores on an agar plate and on the enumeration of colony units formed therein.
2. Culture-independent methods: These methods are based on
the counting of spores under an electron microscope. This method utilizes the hybridization of DNA for the detection of pores. Opto-electric imaging is preferred and considered more efficient because it is faster than all the above processes that have been mentioned. The above processes have the disadvantage of time-consumption.
