Answer:
2
Explanation:
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.
Her teacher suggested that she redraw her graph as a line graph. Why should she redraw the graph?
• A line graph looks better in a scientific report.
• She was measuring a rate of change.
• She had graphed the wrong relationship.
• Her experiment had many different variables.
The correct answer is B. She was measuring a rate of change.
Explanation
A linear graph is a type of graph that contains a series of data represented by points joined by linear segments, which allow you to quickly check the change in the trend of the data. Therefore, inline graphs quantitative variables are usually used to see their behavior over time. According to the above, Anjuli had to use a linear graph to express the information in the graph more clearly, because the data that he was using in his graph were quantitative variables. Also, she wanted to express the respiration rate of the yeast per minute. According to the above, the correct answer is B. Ella She was measuring a rate of change.
Explain what will happen to your eyes when..
a) you move in a very bright light.
b) you move in a dim light
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.
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
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.

The corpus callosum separates the brain into two halves. separates the brain into two halves. is a large network of neurons on the cerebral cortex. is a large network of neurons on the cerebral cortex. is a thick band of neural fibers enabling communication between the two brain hemispheres. is a thick band of neural fibers enabling communication between the two brain hemispheres. describes the hemispheres of the brain
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.

What kind of rock is this?
igneous
Where would this rock most likely be formed?
To which group of rocks would this rock belong?
Rocks can be classified based on texture. The
size of the grains in a rock affects its texture.
Coarse-grained rocks have large grains, and fine-
grained rocks have small grains.
Rocks formed from magma under Earth's surface
have larger grains than rocks formed from lava
on Earth's surface. This is because magma cools
slower underneath the ground than it does above
ground.

Answer:
¿todos los miembros de dicha familia tienen simpatia por las mismas ideas políticas? En las últimas elecciones presidenciales, ¿todos los miembros de dicha familia votaron por el mismo partido?¿Puedes preguntarles cómo votaban los integrantes de esa familia hace veinte años, y hace cincuenta años? ¿Qué ha cambiado? 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.
-el cambio a sido la tecnología y el voto residencial, pues con la tecnología se ha hecho mas fácil el cuento de los votos y el voto residencial a permitido que se les facilite asistir al centro de votación.

Explain why your model improves upon the student’s original model. How would your model help someone who was learning about photosynthesis for the first time? Plato question
Answer:
Due to inclusion of more steps of photosynthesis.
Explanation:
My model is more advance than the student's original model which provides more information about the process of photosynthesis to the learners by explaining various parts of photosynthesis. My model presents the various steps of photosynthesis in a very efficient way with the help of including some extra parts. The student's original model is not more advance so it can't provides more information about the process of photosynthesis so that's why my model provides more information about photosynthesis.
Answer:
This model shows all the major molecules involved in the Calvin cycle and how they change at each stage of the process. This added detail would clarify that the Calvin cycle is a series of complex steps. The student’s original model didn’t show this breakdown at all, and it shows only the final products. This model also shows the number of each molecule created, which the original model doesn’t do.
Using complete sentences, explain how proximity to major rivers influenced the location of early cities.
Answer:
Locations along rivers meant faster travel upstream and downstream to rule territories. The city became the place where the ruler or rulers lived together in a stationary spot. The city's location along early rivers encouraged stronger government, which in turn encouraged stronger cities.
Rivers are one of the most crucial resources that played a major role in the development in ancient times. It led to river valley civilization that influenced the location and kingdoms.
What is river valley civilization?The river valley civilization was one of the most important events that led to the establishment of many kingdoms and regions. The proximity to the river banks influenced many factors.
The cities located on the riverbanks have greater development in services including import, export, travel, agriculture, accessibility, etc. This allowed the people to practice agriculture on a large scale due to the availability of the irrigation system.
The river banks allowed the cities to grow as major trade centers and allowed downstream and upstream travel easier. This also led to the emergence of strong government systems.
Therefore, the proximity to major rivers led to river valley civilization.

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 ______.
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.

Which of the following is not true of integrin? Question 4 options: Integrin molecules serve as stable, permanent anchors that anchor a cell to the extracellular matrix. Integrins undergo extensive conformational changes on binding to molecules on either side of the plasma membrane. Certain intracellular chemical signals can activate integrins from inside the cell, causing them to reach out and grab hold of extracellular structures. When integrin binds to the extracellular matrix, it stretches into an extended, activated state to attach to molecules on the inside of the cell.
Answer:
Integrin molecules serve as stable, permanent anchors that anchor a cell to the extracellular matrix.
Explanation:
Integrins are transmembrane protein receptors that attach the cell cytoskeleton to the extracellular matrix (ECM) in animal cells. These glycoproteins (integrins) are highly dynamic heterodimeric molecules that anchor cells in their position and transduce signals into and out of cells. Integrin-ligand binding activates signaling pathways that are involved in fundamental cellular functions including, among others, organization of the cell cytoskeleton, cell migration, regulation of the cell cycle, etc.
The statement i.e. not true is Integrin molecules serve as stable, permanent anchors that anchor a cell to the extracellular matrix.
