how do plants move carbon from the atmosphere
Explain how carbon is related to each of the examples below. (1 point)
Organic matter
Photosynthesis
Cellular respiration
Organic Matter: Carbon (C) is what makes something organic; if it doesn't contain carbon, then it is not a living thing. For this reason, carbon is often considered the element of life.
Photosynthesis: Carbon is part of the compound Carbon Dioxide (CO2), and CO2 is a reactant in the process known as photosynthesis.
Cellular respiration: Although similar to photosynthesis, cellular respiration contains CO2 as a product, not a reactant, as is the case with photosynthesis.

2. Taking
Explanation:
Food chain is a linear relationship between organisms that depicts the flow of energy from one organism to another. In a food chain, organisms are arranged in trophic levels where arrows pointing to the right direction (➡) are used to show that the organim the arrow is pointing to eats the organism behind it.
Hence, according to this question, arrows in a food chain point from the organism SUPPLYING the energy to the organism TAKING the energy.
What factors limit the size of a cell?
Answer:
Cell size is limited by a cell's surface area to volume ratio. A smaller cell is more effective and transporting materials, including waste products, than a larger cell. Cells come in many different shapes. A cell's function is determined, in part, by its shape.

Explanation:
What are the two main phases of photosynthesis called and why?
Answer:
Photosynthesis takes place through several steps which occur during two stages: the light phase and the dark phase.
Explanation:
In the light-dependent process, which takes place in the grana, the stacked membrane structure within chloroplasts, the direct energy of light helps the plant to make molecules that carry energy for utilization in the dark phase of photosynthesis. The plant uses light energy to generate the co-enzyme Nicotinamide adenine dinucleotide phosphate, or NADPH and ATP, the molecules that carry energy. The chemical bonds in these compounds store the energy and are used during the dark phase
The dark phase, which takes place in the stroma and in the dark when the molecules that carry energy are present, is also known as the Calvin cycle or C3 cycle. The dark phase uses the ATP and NADPH generated in the light phase to make C-C covalent bonds of carbohydrates from carbon dioxide and water, with the chemical ribulose biphosphate or RuBP, a 5-C chemical capturing the carbon dioxide. Six molecules of carbon dioxide enter the cycle, which in turn produces one molecule of glucose or sugar.
Why is so little of the energy passed on?
Answer:
Why is there less energy at each trophic level?
Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level. ... A food chain can usually sustain no more than six energy transfers before all the energy is used up.

Make sure to include your role in the carbon cycle, photosynthesis, and cellular respiration. There is no set length as long as you explain the role of carbon in each process
Answer:
Humans are one of the important contributor for CO2 (Carbon Dioxide) Production. In our body, carbon dioxide is formed intracellularly as a byproduct of metabolism. Carbon Dioxide is transported in the bloodstream to the lungs where it is ultimately removed from the body through exhalation. This process is called Respiration generally Cellular Respiration.
And in Photosynthesis, the exhaled CO2 from human body ( or any other living organisms) are being used as the reactant (with the H2O) then produces Glucose (energy source of plants) and Oxygen (living organisms need to survive). This process takes place in chloroplasts, which contain the chlorophyll.
To sum up, carbon cycle is the process in which carbon travels from the atmosphere into organisms and the Earth and then back into the atmosphere. Plants take carbon dioxide from the air and use it to make food. Animals then eat the food and carbon is stored in their bodies or released as CO2 through respiration.
Therefore, without living organisms there are no carbon dioxide, oxygen and other gases will be produce same as without non-living organisms like gases, the sun, water and etc. human race and other organisms can't survive. And there will be no ecosystem.

Astronomers have two ways of measuring the brightness of a star, apparent magnitude and absolute brightness. Which statement best explains the difference between apparent magnitude and absolute brightness?
Answer:
Astronomers define star brightness in terms of apparent magnitude — how bright the star appears from Earth — and absolute magnitude — how bright the star appears at a standard distance of 32.6 light-years, or 10 parsecs. (A light-year is the distance light travels in one year — about 6 trillion miles, or 10 trillion kilometers.) Astronomers also measure luminosity — the amount of energy (light) that a star emits from its surface.

what would the ploidy of the zygote be if egg and sperm were produced by mitosis rather than meiosis? how would this affect the ploidy of each successive generation?
Answer: the ploidy of the zygote would be genetically identical to the parent cells. since mitosis doesn't reduce the number of chromosomes by half, each successive generation would have twice as many chromosomes as the last.
Explanation:
The ploidy of any zygote formed from egg/sperm produced by mitosis rather than meiosis would be tetraploidy.
Meiosis reduces the diploid chromosome (2N) in parent cells to haploid (n) in the daughter cells. During fertilization two haploid cells (sperm and egg) fuse to form a 2n zygote.
If mitosis replaces meiosis for the production of eggs/sperms, it means eggs and sperms would have complete diploid chromosomes instead of haploid. Thus, during fertilization 2n sperm fuses with 2n egg to form a 4n zygote. A 4n individual is known as a tetraploid.
If mitosis remains as the division for producing eggs and sperms, it means the ploidy level of each successive generation will be doubling from 4n to 8n to 16n, on and on.

B. Identify the species of the beetle and the species of both trees.
C. Determine why the beetle is eating one tree but not the other.
D. Recommend a treatment that will keep the beetles from eating the trees.
ANSWER: B. identify the species of the beetle and the species of both trees (quizlet)
Answer: It's B,
"Identify the species of the beetle and the species of both trees."
The botanist should firstly study the interaction of these organisms in the ecosystem by identifying the species of the beetle and the species of both the trees. Therefore, the correct option is B.
What are species?A species is a group or organisms that can interbreed and produce viable offspring. The concept of species is used to define a unique type of organism, and it is the basic unit of biological classification.
Species are considered to be different from one another if they are unable to interbreed and produce offspring that can survive and reproduce. This definition of species is known as biological species concept.
In the case given in the question, the botanist should first identify the species of both the beetles and the trees. Then try to deduce a relationship between them which could clarify that the reason of the beetles feeding on those specific trees. Hence, the correct option is B.

During transpiration, water moves through a plant and moves out into the atmosphere through the leaves. Transpiration is the result of the interaction of which two parts of a plant?
Transpiration is the evaporation of water at the surfaces of the spongy mesophyll cells in leaves, followed by loss of water vapour through the stomata . Transpiration produces a tension or 'pull' on the water in the xylem vessels by the leaves. Water molecules are cohesive so water is pulled up through the plant.
Transpiration is the outcome of the association between the xylem vessels and stomata present in the leaves.
• The evaporation of water at the surfaces of the spongy mesophyll cells in the leaves succeeded by the loss of water vapor via the stomata is termed transpiration.
• Transpiration generates a pull or tension on the water in the xylem vessels, and these molecules of water are cohesive so pulling up of water takes place through the plant.
• The primary sites of transpiration are the stomates present in the leaves. This stomata comprises two guard cells, which produce a small pore on the leaves' surfaces. These guard cells monitor the closing and opening of the stomates in reaction towards different environmental stimuli, and thus, regulate the loss of water by transpiration.
