Explanation:
Identify the key metabolic process for step I and the key metabolic process for step II, and briefly explain how each process promotes movement of carbon through the cycle. For each process, your explanation should focus on the role of energy in the movement of carbon.
The question is incomplete, however, the correct and complete question is attached as an image:
Answer:
The correct answer is -
Step 1 - photosynthesis, promotes the movement of the carbon cycle because the energy in is sunlight
step 2 - cell respiration, promotes the movement of the carbon cycle the energy out for cell respiration is heat.
Explanation:
Step I is the photosynthesis / Calvin cycle and step II is (cellular) respiration / citric acid cycle / Krebs cycle. Both processes have their particular carbon input and output and the role of energy is also specific to the process.
During Photosynthesis CO2 is the input of carbon in the carbon cycle that Uses solar or light energy come from sunlight or ATP molecules come from light reactions and carbon output is Organic molecules such as glucose or sugars.
During (Cellular) Respiration Organic molecules are the carbon input of the carbon cycle that is broken down uses chemical energy and leads to ATP production and CO2 is carbon output in the carbon cycle.
Cell Junctions help in moving up a level in the hierarchy of organization of living systems. When cell junctions from, the system goes from the cell level to the _________ level.
Which cellular processes are directly controlled by the cell membrane? A. protein production, respiration , digestion of food molecules B. movement of materials, recognition or chemical messages, protection C. enzyme production, elimination of large molecules, duplication of DNA D. release of ATP molecules, regulation of cell production, food production
Answer:
The cell membrane controls the movement of substances in and out of cells and organelles. In this way, it is selectively permeable to ions and organic molecules.
Explanation: I researched this so I hope this helps
The cellular process directly controlled by the cell membranes includes ( B ) :
Movement of materials, recognition or chemical messages, protectionThe cell membrane performs several cellular functions like protection and giving shape to the cell as in humans, also the cell signaling, adhesion and conductivity of ions in and out of the cell are part of the several functions of the cell membrane.
The cell membrane also serves as a point of attachment for extra cellular structures such as glycocalyx.
Therefore we can conclude that the cellular process directly controlled by the cell membranes include : Movement of materials, recognition or chemical messages, protection

Some fungi and insects benefit each other; the fungi protect the insects from predators and the insects spread spores for the fungi. This is an example of a mutualistic relationship.
What is a Mutualistic relationship?A mutualistic relationship may be defined as a +,+ type of interaction in which both species benefit from the existence of each other. Example includes lichens, mycorrhizae association, coral reefs, etc.
In the question, the Fungi protect the insects from predators and benefit the insects to get survivability, while in return insects spread spores for the fungi and assist them in their reproduction process.
Therefore, both insects and fungi undergo a mutualistic type of relationship through which both species benefit from the existence of each other.

Explain how diffusion restored homeostasis during the dialysis treatment.
Explain why countercurrent flow met the goals and why parallel flow did not meet the goals.
Answer:
Explanation:
By maintaining amount of ions in the blood.
Countercurrent flow met the goals due to difference in concentration gradient.
Explanation:
Diffusion restored homeostasis during the dialysis treatment because during dialysis, the concentration of ion in the blood is maintained that leads to homeostasis.
Countercurrent flow met the goals because it flows in opposite direction while on the other hand, parallel flow did not meet the goals because it flows in the same direction. For example. the blood flows in one direction and the dialysate flows in the opposite direction. The countercurrent flow of the blood and dialysate increases the concentration gradient between the blood and dialysate. The increased gradient helps to remove more potassium, phosphorus and urea from the blood. If we used parallel flow so less concentration gradient of solutes is present and hence, less potassium, phosphorus and urea are removed from the blood

The instructions, or 'code', in our DNA is dependent upon the order of the _____ in the DNA
-phosphates
-proteins
-bases
- sugars
Answer:
C. Bases
Explanation:
Deoxyribonucleic acid, commonly known as DNA, is the a type of nucleic acid that serves as the genetic material in living organisms. DNA holds information or instructions needed for the synthesis of useful products like proteins that is responsible for growth, reproduction, and general survival of organisms. Hence, it is referred to as the "BLUEPRINT OF LIFE".
However, in the structure the of the DNA molecule, it contains certain monomeric building blocks called NUCLEOTIDES. These nucleotide bases are of four types namely: Adenine, Thymine, Guanine and Cytosine. It is upon these order of nucleotide bases that instructions, or 'code', in our DNA is dependent upon.

The population change equation is Population Change = (Natality - Mortality) + (Immigration - Emigration). Which equation would create
stable population? (1 point)
natality + immigration = mortality - emigration
O natality + immigration = mortality + emigration
O natality + mortality = immigration + emigration
O natality - immigration = mortality + emigration
Answer:
B. natality + immigration = mortality + emigration
Explanation:
Migration refers to the movement of a group of people from one geographical region (location) to another geographical destination in search of better living conditions, work or social amenities.
Migration selectivity can be defined as the likelihood or tendency that a subset (part) of a group of people are going to move (migrate) out of a particular geographical location or area.
Some of the factors that influence migration selectivity are income level, age, education, gender etc.
Population change equation states that the change in the size of a population over a specific period of time is equal to the sum of the number of births and the number of immigrants that joined.
Mathematically, the population change equation is given by the formula;
Population Change = (Natality - Mortality) + (Immigration - Emigration)
Therefore, the equation which would create a stable population is given by the formula;
Natality + immigration = mortality + emigration.
