During transcription
Answer:
mRNA is “messenger” RNA. ... The process of making mRNA from DNA is called transcription, and it occurs in the nucleus. The mRNA directs the synthesis of proteins, which occurs in the cytoplasm. mRNA formed in the nucleus is transported out of the nucleus and into the cytoplasm where it attaches to the ribosomes.
By what process do glucose and fructose bond together to form sucrose (D)? What is the by-product of this reaction?
Answer: dehydration synthesis; water
Explanation:
When a monomer of glucose and a monomer of fructose combine to create a glycosidic bond during a dehydration reaction, sucrose is the result. One water molecule is lost throughout the process.
What is process do glucose and fructose bond together?The disaccharide sucrose is created through the condensation process between glucose and fructose.
One type of disaccharide is sucrose, also referred to as table sugar. Two monosaccharides are joined to create a disaccharide, which is a type of carbohydrate.
By joining the monosaccharide sugars glucose and fructose, sucrose is a disaccharide, or two-part molecule.
When honeybees ingest plant nectar, they break down the sucrose molecules using an enzyme called an inverstase to produce honey, which is mostly a mixture of sucrose, glucose, and fructose.
Therefore, glycosidic linkage glucose and fructose bond together.

Why must the cell make sure it duplicates its
organelles and DNA before mitosis occurs?
Explanation:
Cells will duplicate or copy their DNA right before they divide. The process of cell division is called mitosis. Since the cell is dividing it needs two copies of its DNA - one is kept by the parent cell and the other is passed to the daughter cell. ... So this process of duplicating DNA is very important.

Using the list of events in the article, complete the diagram to show a cause, its effects, and then the response. Please help me 
:(
Answer and Explanation:
Cause: The plague swept across Europe.
Effects:
1. Production slowed down
2. The price of grain dropped.
3. The population of cities fell
Response: Italians began making wine, oil, and cheese.
(This is correct assuming that the plague occurred first when stated in the article)
So, why is it like this?
We know that a plague is a infectious and super contagious disease that can be transmitted by infected fleas, and is known for killing many people.
So, it makes sense that because this plague happened, we would see a price of grain drop, since the amount of workers were shortened from the plague, and there are less people to buy the grain for the factories and businesses to gain the money from the people's shopping of grains.
That has the production slowed down, so there is less food and grain, and the population would decrease as people were dying from the plague.
This results in the Italians making wine, oil, and cheese to combat the plague.
I'm sorry if this is wrong, and hopefully the article tells you in order the events that occurred. This is my best guess, and what makes sense to me.

what is living thing that work together to coexist?
Answer:
When a group of individual organisms live together in one place we call it a population. A population is defined as a group of organisms from the same species that live together in the same area.
Explanation:
Coexistence: living harmoniously with wildlife in a human-dominated world is a primer on IFAW’s mentality that coexistence is better than conflict. People’s relationship with native wildlife is often that of conflict. Animals such as coyotes, wolves, bears, and beavers are considered “nuisances” and are treated as something to be controlled. The result is millions of animals killed in barbaric ways every year by governments, all to “reduce conflict.” This report highlights examples of people finding innovative, yet simple ways to coexist with wildlife so that we can live side by side with these species. IFAW understands that not only are native wildlife species important to protect, but they are also essential to the ecosystem and therefore our own well-being. We work every day to make the planet a better place for both people and animals.

Question 12 (6 points)
Answer the following relating to PHOTOSYNTHESIS and CELLULAR RESPIRATION
for 2 points each:
1. Identify WHERE each process occurs in cells.
2. Identify what EACH process needs and makes.
3. Explain how photosynthesis AND cellular respiration are important to the carbon
cycle.
1. Photosynthesis occurs in the Chloroplast, which contain a chlorophyll whereas Cellular Respiration takes place in the double-membrane organelle called the mitochondrion.
2. PHOTOSYNTHESIS:
6CO2 + 6H2O → C6H12O6 + 6O2.
The reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll into a sugar molecule and six oxygen molecules, the products.
CELLULAR RESPIRATION :
C6H12O6 + 6O2 → 6CO2 + 6H2O.
The equation for cellular respiration is the direct opposite of photosynthesis.
3. Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.
