the prompt: the diagram above shows how carbon is cycled through the environment. what two processes are most important in maintaining this cycle? make sure your claim is supported with evidence and reasonable. include a rebuttal in your response.
In the environment, the carbon cycle is maintained by two different processes, such as photosynthesis and the decomposition of dead organisms. The carbon level is balanced in this way.
What is the carbon cycle?The carbon cycle carries out its work in the environment and maintains the level of carbon in the atmosphere, and the major source of the carbon cycle is photosynthesis, where the plants take the carbon dioxide and water and, with the help of sunlight, glucose and oxygen are released. Glucose is a carbon-based food that can be used by both plants and animals for cellular activities, resulting in the release of carbon dioxide. Decomposers release carbon into the soil and the atmosphere after living organisms, such as plants and animals, die, and in this way the carbon cycle continues.
Hence, in the environment, the carbon cycle is maintained by two different processes, such as photosynthesis and the decomposition of dead organisms.

pasteur's experiment provided conclusive evidence to reject the spontaneous generation hypothesis, which states that cells arise from nonliving material. as a consequence, his results supported the all-cells-from-cells hypothesis. which element of pasteur's experimental design was most important and why? see section 1.2 (page) .
The Experiment name is 'swan neck flask'.
Since only one of his two treatments employed the same type of nutritious broth and flask, only one of his two treatments was exposed to preexisting cells.
Nutrient Broth- A common culture medium for undemanding microorganisms is nutrient broth. Numerous standardized techniques for analyzing meals, dairy products, water, and other items advocate it.
Pre-existing Cell- All cells originate from previously existing cells, according to the third component of the cell theory definition. This implies that cells are not created spontaneously, as the term "spontaneous genesis" implies. Current cells are constantly used to create new ones.

4. The process by which autotrophs use energy from sunlight to build carbohydrates is called ____________________.
Answer:
photosynthesis
Explanation:
Each cell runs on the chemical energy found mainly in carbohydrate molecules (food), and the majority of these molecules are produced by one process: photosynthesis. Through photosynthesis, certain organisms convert solar energy (sunlight) into chemical energy, which is then used to build carbohydrate molecules.

What is the step of cell division where 2 identical daughter cell are formed?
Answer:
It's MITOSIS.
Explanation: We are also learning about this in class.
During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells. Mitosis itself consists of five active steps, or phases: prophase, prometaphase, metaphase, anaphase, and telophase.
In mitosis of the cell cycle, a eukaryotic cell undergo nuclear division followed by cytoplasmic division results form two genetically identical daughter cells. Mitosis It consist of five phases: prophase, prometaphase, metaphase, anaphase, and telophase.
What is mitosis ?The process in which somatic cell undergo equational division where equal number of daughter cell produced from their parent cell.
Here the number of chromosomes remains the same, except in the case of germ cells where the number of chromosomes become half and the nucleus of a cell is divided into two nuclei having equal amount of genetic material.
nuclear division is followed by cytoplasmic division after the separation of the nucleus. It is important for the growth of the cells and the replacement of worn-out cells.

Cell Length of one side Area of one side of the cube (l × w) Surface area (area of one side × 6 sides) Volume (l × w × h) Surface area / volume Ratio of surface area to volume (for example, 5:1) A 1 cm B 2 cm C 3 cm
The complete question is as follows:
1. What does a surface area/volume ratio of 6:1 mean for the cell’s ability to get the materials it needs that move across its surface?
2. What does a surface area/volume ratio of 3:1 mean for a cell’s ability to get materials across its membrane, compared to the cell with a ratio of 6:1?
Answer:
1 . Surface area to volume ratio = 3 : 1
surface area= 3 cm³ or (l = 1 cm) (1 cm x 1 cm x 3) (W = 3)
volume= 1 cm³ (1cm x 1cm x 1cm)
2. Surface area to volume ratio = 6 : 1
surface area= 6 cm³ or (1 cm x 1 cm x 6 ) (w= 6)
volume= 1 cm³
Diffusion increases with the increase in surface area to volume ratio through the semi-permeable membrane of the cell membrane that allows substances to move into the cytoplasm

Explanation:
Ecosystems are geographical regions made up of biotic factors (plants, animals, bacteria) and non-living or abiotic factors (rocks, rainfall, temperature).
They live in groups called communities within their ecosystem and occupy a specific place in their community, a niche - here, they contribute to nutrient cycling and energy flow. They may often wander in search of food, or shelter in a region known as a habitat.
in a chemical reaction bonds in the reactants molecules are broken and new bonds are formed to yield products. how does an enzyme make this happen an optimal rate in a cell?
Answer:
A. It increases the amount of energy needed to break the bonds in the substrate.
Explanation:
Enzymes are known to be protein-based catalyst. It helps to speed up the chemical reactions that take place in the human body. They actually bind molecules and work in ways to alter chemical reactions. These enzymes are needed for food digestion, reproduction, healing diseases, blood coagulation, etc.
Enzymes help to increase the rate of reaction by lowering the activation energy. Certain enzymes can work to convert substrate to product at million of times faster. As a catalyst, it increases the energy needed to break bonds found in the substrate. This makes the reaction to occur at a faster rate.
A population of 5000 long-horn beetles lives in a tract of forest. What variables would affect the rate at which the population increases or decreases?
Answer: Weather, food competition
The variables that would affect the rate of the population whether it is increase or decrease are as follows;
Environmental conditions.Competition with other organisms. Available resources like food and space.What do you mean by Population?A Population may be defined as a group of individuals belonging to the same species living in the same area at a definite given time.
Environmental conditions vary from place to place which directly affects the rate of the population by influencing the relative fitness of organisms. The competition also inhibits the fitness and survivability of organisms.
It may be intraspecific and interspecific. While food and space together lead to resources that are available for the organisms in order to reproduce themselves under natural conditions.
Therefore, the variables that would affect the rate of the population whether it is increase or decrease are well described above.
