Density independent factors are limited factors whose effect are
Answer:
Any cause that can affect the capacity of the species' population and not taking into consideration the density of the population is referred to as density-independent factors. These are considered as limiting factors that affect the population in cluster or apart. These factors came from physical and chemical development that affect per capita growth rate of the population. If such limiting factor will be suddenly unavailable for organisms to consume, such organism will perish that thereby affect the population size.

Which statement describes an event that occurs during glycolysis that contributes to the production of ATP?
A. Pyruvic acid is broken down to form carbon dioxide.
B. Oxygen molecules are broken down and converted into pyruvic acid.
C. High-energy electrons and hydrogen ions are passed to NAD+ forming NADH.
D. Carbon atoms in glucose are transferred to ADP, forming ATP.
Answer:
C. High-energy electrons and hydrogen ions are passed to NAD+ forming NADH.
Explanation:
The sixth step in glycolysis is the first of the two-energy-conserving reactions of glycolysis which results in the formation of ATP. This step involves the oxidation of glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate.
In the oxidation of glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate, high-energy electrons and hydrogen ions are passed to NAD⁺ forming NADH.
Glyceraldehyde-3-phosphate + inorganic phosphate + NAD⁺ ----> 1,3-bisphosphoglycerate + NADH + H⁺
The NADH produced in this reaction transports the high-energy electrons passed to it through the electron transport chain to produce ATP in oxidative phosphorylation.

The coefficient of viscosity of blood is directly proportional to the frequency of interactions of erythrocytes with the vessel walls. As blood enters small vessels, many erythrocytes tend to flow in the center of the vessel. Given this information, which graphic best describes the effect of vessel diameter on the coefficient of viscosity?.
The coefficient viscosity is the resistance for blood to flow. There is a direct relationship between vessels diametre and viscosity. In the attached files it is the graph that best describes this relationship.
What is blood viscosity?
Viscosity is the property of fluids to resist the tangential displacement of molecule layers.
Blood viscosity refers to the resistance for blood to flow. Blood viscosity depends on the blood density and the vessel diameter.
Viscosity increases when the number of blood cells increases and when more cells get in contact with vessels walls.The more viscose is in the blood, the greater resistance there is to move it, and the more blood pressure it requires to flow through vessels.
Viscosity decreases when blood velocity increases.According to this framework and to the problem statement, we could assume that
smaller vessels ⇒ faster flow ⇒ less wall resistance → less vistositybigger vessels ⇒ slower flow ⇒ more wall resistance → more viscosity
In smaller vessels, blood flow is greater and more cells move in the center, leading to fewer cells interacting with walls. There is higher pressure and less resistance for blood to flow.
In bigger vessels, blood flow is slower, and more cells are interacting with each other and with the vessel walls. There is lower pressure and more resistance for blood to flow.
Since the coefficient of viscosity is directly proportional to the frequency of interactions of erythrocytes with the vessel walls, we can assume that blood flowing through bigger vessels express a higher coefficient of viscosity than blood flowing through smaller vessels.
In the attached files you will find an image representing the relationship between the coefficient of viscosity and vessel diameter.
You should compare this image with your images and choose the correct one.

Explanation:
Cell division is the process by which a parent cell divides into two or more daughter cells.
Cell division usually occurs as part of a larger cell cycle.
Mitosis is a process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells. During cell division, mitosis refers specifically to the separation of the duplicated genetic material carried in the nucleus.
Meiosis takes place in the reproductive organs. It results in the formation of gametes with half the normal chromosome number.
if a cell needs 180 molecules of ATP to perform a function within the cell,home many molecules of glucose and oxygen will be needed. Include in your answer the equation for cellular resperation and how its used to calculate the answer
Answer:
Fill in the word that completes each sentence.
Food contains a sugar called
glucose
which is broken down in a process called cellular
⇒ respiration.
This process uses
⇒ oxygen
Explanation:
The equation for cellular respiration is:
Glucose + Oxygen → Carbon Dioxide + Water + Energy (ATP)
What is cellular respiration?
Cellular respiration is the process by which cells convert the energy stored in food molecules into a form that can be used by the cell, called adenosine triphosphate (ATP). This process occurs in the mitochondria of eukaryotic cells, and in the cytoplasm of prokaryotic cells.
To calculate how many molecules of glucose and oxygen will be needed to produce 180 molecules of ATP, we can use the ratio of ATP produced per molecule of glucose and oxygen consumed.
The standard ratio of ATP produced per molecule of glucose is 36 ATP per molecule of glucose. Therefore, to produce 180 molecules of ATP, the cell would need to consume 5 molecules of glucose.
The standard ratio of ATP produced per molecule of oxygen is 4 ATP per molecule of oxygen. Therefore, to produce 180 molecules of ATP, the cell would need to consume 45 molecules of oxygen.
So, the cell would need 5 molecules of glucose and 45 molecules of oxygen to produce 180 molecules of ATP through cellular respiration.

How do flowers attract pollinators
Answer:
Explanation:
Plants produce nectar to attract pollinators. As the pollinator moves from flower to flower collecting nectar, they are also moving pollen from flower to flower. Certain fruits and seeds will not be produced if their flowers are not pollinated.
Flowering plants need to get pollenDust-like grains that contain male sex cells (gametes) of flowering plants (angiosperms) and cone plants (gymnosperms). Pollen is made on the anthers of flowering plants. from one flower to another, either within a plant for self-pollination or between plants of the same species for cross-pollination to occur. However, pollen can’t move on its own, so animals or the wind (and water in rare cases) move the pollen for plants.
Seven times a number minus the number is -48. Find the number
Answer:
the number should be -(8)
Explanation:
7x-(8) = -56 - 8 = -48
The reason I put it in the format that I did is because if you just put -8, that means that you would multiply 7 by -8 and then instead of subtracting -8 from -56 you would be adding it to -56 so your answer would be incorrect. so by putting the negative outside of the parenthesis that means that the number isn't always going to be negative.
This may be wrong but I hope it helps.
