Answer:
Chromosome condenses
Pairing up to form tetrad
Crossing over
Lining up on metaphase plate
Homologous chromosome separate
Explanation:
Condensation of chromosomes occurs in prophase I phase. Pairing up to form tetrad occur during prophase I. Crossing over occurs during prophase I of meiosis cell division. Chromosomes line up along the metaphase plate in the stage of Metaphase. Centromeres break down and homologous chromosomes separate in anaphase I phase of meiosis.
Why is carbon special compared to other elements?
Answer: Carbon is the only element that can form so many different compounds because each carbon atom can form four chemical bonds to other atoms
Explanation:
because the carbon atom is just the right, small size to fit in comfortably as parts of very large molecules. Having the atomic number 6, every carbon atom has a total of six electrons.
Answer: Carbon is the only element that can form so many different compounds because each carbon atom can form four chemical bonds to other atoms, and because the carbon atom is just the right, small size to fit in comfortably as parts of very large molecules.
Explanation: Carbon's characteristics include its ability to bond with oxygen, hydrogen, nitrogen, phosphorus and sulfur. Carbon biochemical compounds are essential to all life on the planet. Carbon atoms can bond to one another and form different structures. Which is not a function of proteins.

How does energy flow (move) in a food chain?
Answer:
Like the primary producers, the primary consumers are in turn eaten, but by secondary consumers. This is how energy flows from one trophic level to the next. Living things need energy to grow, breathe, reproduce, and move. At the bottom of a food chain is always the primary producer.

Which of the following is not accounted for by cell theory?
A. the growth and reproduction of unicellular organisms
B.the generation and replacement of cells in multicellular organisms
C. the origin and nature of the very first cells, from which all other cells derive
D. the existence of erythrocytes, neurons, and other cells that do not reproduce
Answer:
Answer C is the answer to your question
The statement which is not accounted for by cell theory is as follows:
The origin and nature of the very first cells, from which all other cells derive.Thus, the correct option is C.
What is Cell theory?Cell theory was proposed by a German botanist M.J. Schleiden and a German zoologist T. Schwann. According to them, the cell theory states that:
All living organisms whether it is plant or animal is made up of cell. A cell is the smallest unit of all living organisms. The Cell is the structural and functional unit of organisms.Later in 1855, the cell theory is further refined by German biologist R. Virchow. According to him, all cells are arising from pre-existing cells.
So, cell theory never illustrates any evidence about the origin and nature of the very first cells, from which all other cells derive.
Therefore, the correct option for this question is C.

Explanation:
In recent years, scientists have collected data on populations of Adelie and Gentoo penguins. Adelie penguins are ice dependent. They rely on sea ice as a foraging platform for feeding on prey such a krill and fish, while Gentoo penguins are considered ice-intolerant. How does the data in the graph support or refute the theory of global climate change?
a. The graph refutes this theory, as it shows increases in Adelie and Gentoo penguins.
b. The graph supports this theory, as it shows that penguin populations are fluctuating in number.
c. The graph supports this theory, as it shows a gradual decline in populations of Adelie penguins.
d. The graph refutes this theory, because it does not provide any information on global temperatures.
Answer:
C. The graph supports this theory, as it shows a gradual decline in populations of Adelie penguins.
Explanation:
Since Adelie penguins depend on ice to survive, a decline of ice would spell chaos for their survival. And coupled with the fact global warming means a bigger fluctuation of temperatures and a faster melting of ice on Earth, that would line up with the data of the decreasing Adelie penguins.

The pyruvate dehydrogenase complex is subject to allosteric control, especially inhibition by reaction products. The main regulatory process controlling pyruvate dehydrogenase's activity in eukaryotes is
Answer:
phosphorylation by ATP and dephosphorylation, which turn off/on the complex
Explanation:
The pyruvate dehydrogenase complex consists of three different enzymes capable of converting pyruvate into acetyl-CoA. The enzymes that form the pyruvate dehydrogenase complex are pyruvate dehydrogenase (E1), dihydrolipoyl transacetylase (E2) and dihydrolipoyl dehydrogenase (E3). In eukaryotic organisms, the pyruvate dehydrogenase complex is controlled by pyruvate dehydrogenase kinase and pyruvate dehydrogenase phosphatase, which turn off and turn on the complex, respectively. In this mechanism, pyruvate dehydrogenase kinase phosphorylates (using ATP) to target serine residues in E1 subunit, while pyruvate dehydrogenase phosphatase dephosphorylates this subunit, thereby deactivating and activating the complex, respectively.

Write a 750-1,000-word essay about water quality in your community that addresses the following points:
1. Obtain a water quality report from your local municipality within the last two years and discuss what you found in the report?
2. Identify a water quality issue happening in your community and where the pollution comes from? This includes point sources (for example, water discharge from a factory; contamination from a Superfund site), Non-point sources (for example, agricultural runoff), and Natural sources.
3. Describe how the pollution source is impacting the environment and human health in your community, and provide two examples of each.
4. Identify three management practices to minimize water pollution.
5. Remember to support your data and information with appropriate citations. A minimum of five peer-reviewed references must be included.
Water is a precious resource that is essential for life. It is used for drinking, bathing, cooking, cleaning, and growing food. Water quality is the condition of water in terms of its physical, chemical, and biological properties. Water quality can be affected by a variety of factors, including pollution, climate change, and natural events.
Water Quality Report
I obtained a water quality report from the City of Lucknow: https://lmc.up.nic.in/ for the year 2022. The report found that the water quality in Lucknow is generally good. However, there are some areas where the water quality is not meeting standards. For example, the report found that the levels of coliform bacteria in some areas of the city are above the safe drinking water standard. Coliform bacteria are a type of bacteria that can cause diarrhea and other health problems.
Water Quality Issue
One of the main water quality issues in Lucknow is pollution from agricultural runoff. Agricultural runoff is the water that flows off of agricultural land after it has been used to irrigate crops or to wash away manure and other waste products. Agricultural runoff can contain a variety of pollutants, including pesticides, fertilizers, and animal waste. These pollutants can contaminate surface water and groundwater, and can harm aquatic life and human health.
Another water quality issue in Lucknow is pollution from sewage treatment plants. Sewage treatment plants are designed to remove pollutants from wastewater. However, if sewage treatment plants are not properly maintained, they can discharge pollutants into the environment. These pollutants can contaminate surface water and groundwater, and can harm aquatic life and human health.
Impact of Pollution
The pollution from agricultural runoff and sewage treatment plants is impacting the environment and human health in a number of ways.
Impact on the environment: The pollution from agricultural runoff and sewage treatment plants is harming aquatic life. The pollutants can kill fish and other aquatic animals, and can also make the water unsafe for swimming and fishing. The pollution is also harming the watershed, which is the area of land that drains into a river or lake. The pollutants can damage the soil, and can also make the water unsafe for drinking.Impact on human health: The pollution from agricultural runoff and sewage treatment plants is also harming human health. The pollutants can cause a variety of health problems, including diarrhea, vomiting, nausea, and stomach cramps. The pollutants can also cause long-term health problems, such as cancer and reproductive problems.Management Practices
There are a number of management practices that can be used to minimize water pollution. These practices include:
Preventing pollution at the source: This can be done by using less pesticides and fertilizers, and by properly disposing of animal waste.Treating wastewater before it is discharged into the environment: This can be done by installing and maintaining sewage treatment plants.Restoring degraded watersheds: This can be done by planting trees and other vegetation, and by reducing erosion.Educating the public about water quality: This can help people to understand the importance of protecting water resources, and to make choices that reduce pollution.Conclusion
Water quality is a critical issue in Lucknow. The pollution from agricultural runoff and sewage treatment plants is harming the environment and human health. There are a number of management practices that can be used to minimize water pollution. It is important to implement these practices to protect our water resources and ensure the health of our community.
