While working with cultured mouse cells, a researcher unknowingly treated the cells with a mutagen that causes the deletion or insertion of individual nucleotides in DNA. Subsequently, she isolated and cultured a single cell from this group. She noticed that the progeny of this cell were not producing a certain protein and that this affected their survival. The mutation would be most harmful to the cells if it resulted in ______.
Answers
Answer:
The correct answer is - a single nucleotide insertion near the start of the coding sequence.
Explanation:
Insertion mutations are the mutation that takes place when there is an extra nucleotide is added to the DNA strand during replication and causing the particular protein translation or inhibits the translation if present at the start codon.
It did not allows the translation in this sequence, Deletion, and insertion both are a dangerous mutation that causes the production of unwanted protein or not producing the protein and if this protein is essential for surviving it will lead to cell death.

Located in China you have blade-like pillars of limestone and sandstone, often over 10m tall. A wonderful landscape that looks parallel to a forest of stone is appropriately named the Stone Forest. The stone forest was constructed in a shallow sea about 270 million years ago. Sandstone and limestone compiled in the bay over time and were ultimately pushed upwards towards the sky. The rocks then began to be molded by wind and water of the surface to create the impressive and grand stone statues they are today.
Giant's Causeway
In Northern Ireland, exist over 40,000 enormous hexagonal black pillars each with some irregular sides, jutting out of the cliff. All of these irregular pillars mesh neatly together appearing as steps. They were established after volcanic eruptions about 50-60 million years ago during the Paleogene Period. It was assumed that the speed at which the lava cooled may have to do with the sizes and shapes of the columns. However, the volcano that was the cause of the columns can no longer be seen today, it has vanished due to erosion.
Ha Long Bay
There stands a glorious terrain formed of limestone pillars and caves located in Vietnam. The rocks have been forged by the sea falling and rising over an estimated 500 million years. The bay also consists of over 1600 islands, a large portion of which remain uninhabited. However, the handful of Islands that contain civilization are fishing villages with towns built on the water. According to the towns peoples stories, it was dragons that created the islands and pillars of rocks to protect Vietnam from invaders.

A pesticide tolerance refers to the a. amount of a pesticide that can be applied to a food and how much of the pesticide that is permitted to remain on the food in the marketplace. b. ability of the liver to detoxify a pesticide c. toxicity of the pesticide in the laboratory d. number of pests that are killed by a selected dose of the pesticide
Answers
Answer:
a. amount of a pesticide that can be applied to a food and how much of the pesticide that is permitted to remain on the food in the marketplace.
Explanation:
Pesticides are chemical substances used to get rid of or kill pests that attack crops on farmlands. These pesticides, although help the farmer to get rid of his pest problem and likely have an increase in yield, are dangerous to human and animal health if consumed.
As set up by the Environmental Protection Agency (EPA), pesticide tolerance is the amount or quantity of pesticide chemical that can be applied to a food and how much of the pesticide that is permitted to remain on the food in the marketplace.
Sickle-cell anemia is caused by a mutation that changes the second nucleotide of the codon from GAG to GUG. This results in a change of the amino acid from glutamic acid to valine. If the mutation affected the third nucleotide of the codon and changed GAG to GAU then the amino acid would change from a glutamic acid to aspartic acid. Would you predict this change to have the same effect
Answers
Answer:
This change would be predicted to have less effect compared to the change of the amino acid from glutamic acid to valine.
Explanation:
A conservative mutation is a type of mutation that leads to the replacement of one amino acid by another with similar properties. Both glutamic acid and aspartic acid are similar in size and biochemical properties. These amino acids are acidic dicarboxylic acids (i.e., they contain two carboxyl groups or ―COOH). The side chains of both glutamic acid and aspartic acid are similar, with the exception that glutamic acid contains one additional methylene group in its side chain.

Answers
Answer:
is a thick band of neural fibers enabling communication between the two brain hemispheres.
Explanation:
A brain can be defined as an organ of soft nerve tissue that is found in the skull of vertebrates and it's typically responsible for the coordination of nervous activities, intellect and sensation.
The human brain consists of various sections and these includes;
I. Anterior Cingulate Cortex (ACC) which resembles a bow or collar surrounding the frontal part of the corpus callosum. This is the frontal part of the cingulate cortex which helps to make complex cognitive functions such as impulse control, decision-making, emotions and empathy.
II. Ventral prefrontal cortex in humans are interconnected with the brain and are responsible for the processing of risk, empathy, fear and social decision-making
III. The Cerebral Cortex: this part of the brain primarily comprises of grey matter, foldable sheets of neurons and forms its outermost layer. Therefore, cerebral cortex is known as the outermost layer of the brain (cerebrum) and thus, makes up half of its weight. It is about 2.5 millimeters in thickness and as such it's able to fold.
The corpus callosum is a large, thick band of C-shaped neural fibers found beneath the cerebral cortex and it's saddled with the responsibility of enabling communication between the two brain hemispheres i.e the right hemisphere and the left hemisphere.
Explain what will happen to your eyes when..

b) you move in a dim light
Answers
Answer:
For A your pupils will shrink for B your pupils will dilate.
Answer:
When you look at something that is bright, your pupil may shrink.
When you look at something dim, your pupil may get larger.
Explanation:
I think your pupil may get larger if you look at dim light because your eye may have a hard time seeing what's going on. And the opposite may happen when you look at bright light.

B) A polysaccharide consisting of 2 types of monosaccharide units and cross-linking oligopeptides. C) A polysaccharide consisting of 3 types of monosaccharide units and cross-linking oligopeptides. D) Two different polysaccharides and 1 type of oligopeptide, which are cross-linked.
Answers
Answer:
B) A polysaccharide consisting of 2 types of monosaccharide units and cross-linking oligopeptides.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
Also, a unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
A bacterial cell is made up of peptidoglycan and its main function is to maintain the shape of a cell while preventing it from bursting due to osmotic pressure. Also, the bacterial cell inhibits the passage of larger molecules but allows the free movement (passage) of smaller molecules in the body of a living organism.
Basically, bacterial cell wall comprises a polysaccharide that's typically made up of two (2) types of monosaccharide units and cross-linking oligopeptides.
Anjuli performed an experiment to determine the respiration rate of yeast. She determined this by measuring the
amount of carbon dioxide (CO2) that was produced. Then, she created the following graph.

mapa mental sobre El origen de las especies

El origen de las especies, cuya primera edición apareció en 1859, es el libro más conocido de El biólogo británico Charles Darwin. En el libro, Darwin expone su teoría de la evolución:
Afirma que toda la vida en la Tierra tiene un ancestro común. Que la selección natural es el mecanismo principal para la evolución de las especies.El libro está considerado como una de las obras científicas más importantes de la historia. Causó revuelo en el momento de su publicación porque atribuyó la riqueza de la forma de vida en la Tierra a un proceso mecánico más que a una inteligencia sobrenatural. Es cierto que otros habían sugerido previamente que podría haber cosas como la evolución o la selección natural, pero "El origen de las especies" es el primer trabajo que extrae la mayor consecuencia de estos conceptos.

Escribe en tu cuaderno tus averiguaciones
Explanation:
Mi familia tiene diferentes ideales políticos y por eso votaron por diferentes partidos, antes el proceso era manual
En las elecciones actuales les he preguntado a los miembros de mi familia y no todos votaron por el mismo partido político unos creen en uno de los partidos políticos y otros creen en otros. Por lo tanto no todos simpatizan con las mismas ideas políticas
Anteriormente se votaba por medio de un papel escrito, entonces el proceso es mucho más lento y menos automatizado que con maquinas
No, cada familiar tiene una idea política distinta.
-no votaron por el mismo partido político pues siempre algunos presidentes hacen promesas y no las cumplen.
-las votaciones siempre las han realizado por numero de DUI, en institutos o en las calles frente a las alcaldías, tenían que buscar el numero de urna en la cual estaban asignados.
