Describe the steps of how a protein is specifically made.
Include both Transcription, Translation & protein folding (all levels)
Answers
Answer:
Ok. Let me explain.
Explanation:
First of all this process starts from genes in DNA.
At first an enzyme called RNApolymraze،makes a copy of one strand of DNA. We call the copied strand mRNA (messenger RNA). This stage is called transcription . This mRNA leaves nucleus from nucleus pores and enters the cytoplasm.
When the mRNA reaches a ribosome. Another process starts which is called translation.
In translation a special RNA which is called tRNA that has an amino acid attached to it ،enters the ribosome. Every three code on mRNA is a code of special amino acid so when the code on tRNA and mRNA are suitable، different amino acids bond together with peptide bond.
After this process the peptide chain is produced
Every protein has four structures until it can be used.
First structure is peptide chain. It is after the translation.
The second structure this peptide chain makes alpha helix and beta sheet.
The third structure it makes a shape like T or a kind of plant in persian :(برگ شبدر)
The fourth structure is when it folds with aid of tao protein and now it can be used.
Describe what lines up at the cell's equator during metaphase 1 of meiosis
Answers
During metaphase, spindle fibers attach to the centromere of each pair of sister chromatids. The sister chromatids line up at the equator, or center, of the cell. This is also known as the metaphase plate. The spindle fibers ensure that sister chromatids will separate and go to different daughter cells when the cell divides.

What happens to the energy that is passed through to the primary consumer? List three possibilities
Please help
Answers
Answer: Primary consumers only obtain a fraction of the total solar energy—about 10%—captured by the producers they eat. The other 90% is used by the producer for growth, reproduction, and survival, or it is lost as heat. You can probably see where this is going. Primary consumers are eaten by secondary consumers.
Explanation:
The energy that is passed through to the primary consumer is only 10% of their total energy as 90% of energy is lost in the metabolic process or excretions process.
The flow of energy in any ecosystem is linear from the sun to the consumers in an ecosystem. Energy is transferred from each trophic level to the next, however, only 10% of the energy of each level is transferred other 90% of energy is lost in the various process:
transferred to the next trophic level: If energy passed through the primary consumer then 10% of the total energy will transfer to the secondary consumerLost as heat or metabolic process: Most of the part of the energy is lost in performing various cellular functions and metabolic functions such as cellular respiration, digestion, reproduction, and others.Lost in excretion: some part of the energy is also lost in the excretion process.Thus, the correct answer and possibilities are given above.

Which process requires the expenditure of
cellular energy?
A. passive transport
B.
active transport
C. osmosis
D. diffusion
Answers
Answer:
D Difusion......
help ...
Active transport requires the expenditure of cellular energy. Therefore option B is correct.
Active transport is a process that requires the expenditure of cellular energy, typically in the form of adenosine triphosphate (ATP).
In active transport, molecules or ions are moved against their concentration gradient, from an area of lower concentration to an area of higher concentration.
This movement against the concentration gradient requires energy to be expended by specific carrier proteins or pumps embedded in the cell membrane.
These pumps actively transport substances across the membrane, maintaining concentration gradients and facilitating the uptake of essential nutrients or the removal of waste products from the cell.
Passive transport, osmosis, and diffusion, on the other hand, do not require energy as they occur spontaneously along concentration gradients.
Therefore option B Active transport is correct.

Explanation:
Answer:
Both are natural hazards that affect Florida.
Both may affect coastal and inland regions.
Both may be caused by thunderstorms.
Both may cause property destruction.
Explanation:
Wildfires increase the potential for flooding, debris flows, and landslides. Smoke and other emissions contain pollutants that can cause significant health problems. they also threaten lives directly, and wildfire smoke can affect us all. They spread air pollution not only nearby, but thousands of miles away—causing breathing difficulties in even healthy individuals, not to mention children, older adults and those with heart disease, diabetes, asthma, COPD and other lung diseases.
On the other hand Standing flood waters can also spread infectious diseases, contain chemical hazards, and cause injuries. Each year, flooding causes more deaths than any other hazard related to thunderstorms. The most common flood deaths occur when a vehicle is driven into hazardous flood waters.
Which is the final electron acceptor in the electron transport chain of cellular respiration?
NADH
FADH2
oxygen
carbon dioxide
Answers
Answer:
The answer is Oxygen .. so the name "oxidative phosphorelaton".
ETC is the part of cellular respiration to break sugar into energy. Oxygen is the final electron acceptor in the ETC of the cellular respiration process. Thus, option c is correct.
What is ETC?ETC is abbreviated for electron transport chain. It is one of the steps of the cellular respiration process that is involved in breaking the sugar molecule and oxygen into carbon dioxide, water, and energy. It uses electron and protein complexes to move the ions.
The oxygen acts as the final acceptor of the electron in the ETC due to its high electronegativity and affinity that allows it to accept electrons which leads to the formation of water as the byproduct. This further proceeds to the oxidative phosphorylation step.
Therefore, option c. oxygen accepts electrons in ETC.

Feral pigs are an invasive species commonly found in the Pineywoods of East Texas. Areas where feral pigs are found often have damaged farmlands, grass, and tree roots. When the pigs live close to water sources, their presence erodes the soil. This disrupts the native vegetation and makes those plants vulnerable to invasive plant species. There are no known predators to feral pigs.
How will the removal of the feral pig affect existing populations in that ecosystem?
A- Removing the pigs will not affect the ecosystem because the pigs have no natural predators that will be affected by their removal.
B- Removing the pigs will cause an increase in native plant populations over generations because the pigs will no longer damage the land.
C- Removing the pigs will cause the native vegetation to become quickly overgrown because the plants will no longer be the prey of the pigs.
D- Removing the pigs will cause an increase in invasive plant populations because the pigs were the only organism eating invasive plants.
Answers
Answer:
B.
Explanation:
In the excerpt, it says that the pigs eat the native plants, and disrupt the land.
So by taking the pigs out of the ecosystem, it will result in the native plants growing again, and the land forming back to normal.
The statement (B) is correct. Removing the pigs will cause an increase in native plant populations over generations because the pigs will no longer damage the land.
What do you mean by native plants?They are plants that have been growing in a particular habitat and region, typically for thousands of years or longer. Also called indigenous, they are well adapted to the climate, light, and soil conditions that characterize their ecosystem.
Moreover, a native species is found in a certain ecosystem due to natural processes such as natural distribution. The koala, for example, is native to Australia. No human intervention brought a native species to the area or influenced its spread to that area.
Hence, native trees: Palash, Indian Coral tree, Sita Ashok, Indian cork tree, Neem, Peepal, Kadamba, Karanj. Native shrubs: Kanchan, Shankasur, Ratrani, Mehendi, Gulmehndi, Parijatak. Native seasonal flowers: Utricularia, Balsam, Eriocaulon, Smithia.

D : Eclipsing Binary
Credits go to the person above me.

Explanation:
EDGE 2021
The phenomenon that is being described in this scenario is an eclipsing binary.
An eclipsing binary is a type of binary star system in which one star passes in front of the other, causing a periodic decrease in brightness as seen from Earth. This occurs because the star in front blocks some of the light emitted by the star behind it.
In an eclipsing binary, the period and depth of the eclipses can be used to determine the sizes and masses of the stars, as well as their distance from Earth. Therefore, eclipsing binaries are important tools for astronomers to study the properties of stars and their evolution.
