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.
If an environment experiences change, which BEST predicts the population that is MOST LIKELY to survive?
Answer:
the population that reproduces sexually and undergoes meiosis
Explanation:
the population that reproduces asexually and undergoes mitosis
the population that reproduces sexually and undergoes mitosis
the population that reproduces asexually and undergoes meiosis
the population that reproduces sexually and undergoes meiosis
The correct answer would be the population that reproduces sexually and undergoes meiosis.
Meiosis is always related to sexual reproduction. It leads to the production of sex gametes that participate in fertilization. During meiosis, genes are recombined and the gametes genetically variable from their parents. The genetic variation ensures that sexually produced organisms have the inherent ability to adapt to changes in their environment.
This is unlike asexually produced organisms. They are produced by mitosis and no form of gene recombination occurs. Hence, they are genetically identical to their parents. This means that a single change to the environment can wipe out both the parents and their offspring.
Therefore, the only population that can survive adverse changes to the environment is the population that reproduces sexually and undergoes meiosis.
Let's bring what you have learned about the carbon cyde, photosynthesis, and cellular respiration and show how they are connected work together in an ecosystem. Play the role of a carbon atom in an ecosystem. Start with the production, how are they made? And then explain how they transform through different processes. 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.

The middle layer contains smooth muscle tissue, which contracts and relaxes to push blood. It also contains elastic connective tissue, which helps to regulate blood pressure. How do the two tissues in the middle layer relate to the artery's function?
Answer and explanation:
Arteries are the blood vessels that take blood from the heart to the tissues where it's needed. For this task to be achieved, arteries have different structures and properties in each of their layers.
Arteries have 3 layers, also called tunicas: the intima (in contact with the blood), the media, and the adventitia (the most external layer).
The media -or middle layer- is composed of smooth muscle tissue and elastic connective tissue. This tunica is usually the thickest of the three and has a hugely important role in blood flow and blood pressure regulation.
Blood pressure (BP) is a variable that the body needs to maintain in a range for everything to work effectively. When blood pressure falls, the middle layer of the artery contracts (both in response to the change in blood flow and thanks to the action of specific hormones) so blood can flow somewhat faster and compensate for the disturbance in BP. On the other hand, when blood pressure rises, the middle layer of the artery dilates, to make the blood flow slower.
Smooth muscle tissue is fundamental for contraction, while elastic connective tissue is needed for dilatation.
Answer:
D. The two tissues contain different types of cells, and each type performs different functions.

How are photosynthesis, cellular respiration, and the carbon cycle all related?
respond with a full paragraph (3-5 sentences)
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.
Answer:
Cellular respiration and photosynthesis are important parts of the carbon cycle.
The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth. While cellular respiration releases carbon dioxide into the environment and produces ATP thanks to oxygen and glucose, photosynthesis pulls carbon dioxide out of the atmosphere and produces oxygen and nutrients from water and CO2

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.

One day, at a certain time, a student measured the shadow of a fence and found that it was 2 m long. The next day, she measured the shadow of the same fence at a different time and found that it was 3 m. long. What can you infer about the time of day at which the student measured the shadows? Explain.
Answer:
The time of day the second time the student measured the length of the fence shadow was either earlier or later than the first time she measured the shadow.
Explanation:
As the first time the student measured the shadow of the fence gave an answer of 2 meters, the second time gave an answer of 3 meters. For this reason, the shadow is longer in length. This means that the sun is closer to the horizon, yielding a light beam that is closer to the ground.
Moreover, if the sun was directly above the fence post, there would be no shadow. However, because the sun is closer to the horizon, showing that it is earlier or later then the first measurement, the second measurement has a longer shadow.

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.

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.
