Competition is one of the factors that limit the population density and is dependent on the density. Thus option 3 is correct.
What is the competition?Competition is a density-dependent limiting factor the more the individual lies in an area the more resources they take up and hence this type of fact is a major factor that represents the evolution of the species and is dependent on the population diversity.

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.
A man with type a blood married a woman with type B.Their offspring will be AB blood. The pattern of inheritance is called
Answer:
Codominance
Explanation:
Their offspring receives one version of a gene, called an allele, from each parent.
This means neither parent is dominant over the other in the inheritance pattern, so it is called codominance.
Heather and Matthew take 60 sec to walk eastward along a straight road to a store 90 m away. What was their speed?
Answer:
1.5m/s
Explanation:
Using the formula;
Speed (m/s) = distance (metres) ÷ time (seconds)
According to the information provided in this question, Heather and Matthew spend 60seconds to travel a distance of 90 metres. This means that t = 60s, d = 90m
Hence,
Speed = 90/60
Speed = 3/2
Speed = 1.5m/s.

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.

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.

D. stratosphere
What is the theory of natural selection, and why does it occur in an organism? Give an example.
Answer:
It occurs in organisms because an organism with a beneficial trait/mutation have a higher chnace of surviving compared to organisms that do not. So the organsims that do survive pass on their genes to the next generation, and the bext generation will pass on those genes to the generation after and so on. But all the organisms that do not possess a beneficial trait/mutations will not survive, therefore they cannot reproduce and pass on those genes to their offspring. This means that most of the population will posses that trait/mutation.
Example: Spotted moths camouflage with bark so they are seen by predators and eaten. Black moths are easily seen by predators and are eaten. Spotted moths then pass on their genes to the next generation of moths.
in the process of meiosis the new cells have half the dna of the original cell why is this important to life HELP PLEASE THIS IS DUE IN 1 MINUTE
Answer:
Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. During meiosis one cell divides twice to form four daughter cells.
This is because meiosis creates cells that are destined to become gametes (or reproductive cells), this reduction in chromosome number is critical — without it, the union of two gametes during fertilization would result in offspring with twice the normal number of chromosomes to make a human child.
In photosynthesis, what gives energy to the electron moving through the electron transport chain?
A.
water
B.
NADPH
C.
light
D.
ATP
Answer:
In photosynthesis, light gives energy to the electron moving through the electron transport chain. So its C.
Explanation:
In the photosynthesis of plants, the light gives energy to the electrons passing through the electron conveyor chain. This Light energy is then transformed to chemical energy, which creates ATP; an energy storehouse molecule, and NADPH, a decreased electron transport. Moreover, light energy is utilized to elevate protons across a membrane to compose a proton-motive force.
