In eukaryotes, gene expression is regulated mostly by _____.
Answers
Answer:
Gene expression in eukaryotic cells is regulated by repressors as well as by transcriptional activators. Like their prokaryotic counterparts, eukaryotic repressors bind to specific DNA sequences and inhibit transcription.
Explanation:
In eukaryotes, gene expression is regulated mostly by transcription factors.
What are transcription factors?Transcription factors are proteins that bind to DNA in the promoter region of a gene, and they play a critical role in controlling when and to what extent a gene is expressed.
They can either activate or repress gene expression by promoting or inhibiting the recruitment of RNA polymerase. Transcription factors are themselves regulated by a variety of signals, including hormones, growth factors, and other external cues, as well as by feedback loops and other regulatory mechanisms within the cell.
Ultimately, this complex interplay of factors allows eukaryotic cells to precisely control which genes are expressed, when they are expressed, and to what degree, enabling them to respond to changing internal and external environments.

what will happen to a population of organisms that are in an oxygen rich environment. (Double click the story board to draw on it)
Answers
Answer
I'll assume this means adding additional oxygen to the atmosphere.
Paper airplanes now fly farther. With all that extra air, the air pressure near the surface increases significantly. Gliders, parachutists, birds and paper-plane hobbyists enjoy greatly improved performance.
Everyone gets better gas mileage. Oxygen-enriched air improves engine performance by producing hotter reactions and reducing the proportion of nitrogen, which reduces heat transfer (Page on Energy.gov)
Higher elevation Biomes become inhabited by more vertebrates. Areas such as the high Himalayas or high Andes are no longer off-limits to animals without special adaptations to increase their levels of hemoglobin.
Insects of unusual size. Many insects rely on gaseous diffusion to for respiration, therefore the maximum body size depends on the proportion of oxygen gas in the atmosphere. Most bugs get bigger, some smaller (see Atmospheric oxygen level and the evolution of insect body size)
Everyone feels more alert, active, and happier. All that fresh oxygen improve our cognition, alertness, and physical performance. As a result, most athletic records would likely be broken by oxygen-enriched athletes.
We get sick less often. Neutrophils, soldiers of the immune system, destroy bacteria by using NADP oxidase to pump ions into, and disrupt, intruding cell's membranes causing rupture. More oxygen, more oxidase. (Page on Nih.gov)
We die younger. Free radicals (i.e. O2-) are thought to exacerbate the aging process through Oxidative stress, which interferes in numerous cellular processes: protein production, DNA replication, intercellular communication, and are also thought to contribute to MS, Alzheimers, Parkinsons, and a host of other ailments.

what are the functions of the kidney
Answers
The kidneys are essential for homeostasis (maintaining a constant internal environment) of the body's extracellular fluids. Their basic functions include:
1. Regulation of extracellular fluid volume. The kidneys work to ensure an adequate quantity of plasma to keep blood flowing to vital organs.
2. Regulation of osmolarity. The kidneys help keep extracellular fluid from becoming too dilute or concentrated with respect to the solutes carried in the fluid.
3. Regulation of ion concentrations. The kidneys are responsible for maintaining relatively constant levels of key ions including sodium, potassium and calcium.
4. Regulation of pH. The kidneys prevent blood plasma from becoming too acidic or basic by regulating ions.
5. Excretion of wastes and toxins. The kidneys filter out a variety of water-soluble waste products and environmental toxins into the urine for excretion.
6. Production of hormones. The kidneys produce erthryopoietin, which stimulates red blood cell synthesis, and renin, which helps control salt and water balance and blood pressure. They are also involved in regulating plasma calcium and glucose levels.

what is the ultimate source of electrons for photosynthesis in plants?
Answers
Answer: Water
Explanation:
What is the ultimate source of electrons for photosynthesis?
In photosynthesis, water is the source of electrons and their final destination is NADP+ to make NADPH
Photosynthesis is a plant process to make food and energy. It includes various steps to release energy. The water molecule is the ultimate electron donor in the process.
What is photosynthesis?Photosynthesis is said to be the process that converts solar energy into the chemicals that are used as the energy source in cellular respiration activities. Here, sunlight, carbon dioxide, and water act as reactants.
The carbon dioxide and water undergo splitting by the membrane pigments and then the electron produced from water is carried with enzymes to make NADP⁺. This is further used to make NADPH. As result oxygen along with the sugar molecules are produced and are rich in ATP.
Therefore, water is the foremost source of electrons for photosynthesis in plants.

(Hope this helps can I pls have brainlist (crown)☺️)
Explanation:
They consume food and they have much higher metabolism. That means that more waste products are produced. Plants can use much of the waste produced and it is in fact raw material. Animals don't normally produce their own chemicals from scratch like plants normally do so they can't just recycle the waste. They need to remove it. About the only waste plants need to get rid of is excess oxygen produced during the day. That is actually three reasons but recycling is related to plants not consuming but making their own chemicals from scratch. In a way it pretty much comes down to one main reason.

Answers
Answer:
Explain how kinetic energy affects each object as it changes its state of matter:
A) Water boiling:
B) Popsicle freezing:
C) Water condensing on the side of a water bottle:
Explanation:
A) A water boiling will result in evaporation, therefore the particles will move extensively faster than liquid due to it being vapor.
B) A popsicle freezing is originally a solid so it'll have the least amount of kinetic energy as the particles remain fairly slow.
C) Due to the fact that water is condensing, while turning into a liquid. The water condensing on the side of the water bottle would produce a lower kinetic energy level due to the fact that it's becoming a liquid. Though liquids have higher kinetic energy than solids, as gases have a higher kinetic energy compared to liquids.
Evaporation from boiling water causes the particles to move much more quickly than they would in a liquid state.
What is Kinetic energy?A popsicle is initially a solid, it will have the least kinetic energy because the particles are still moving slowly. Because water is condensing as it transforms into a liquid.
Because it is turning into a liquid, the water that is condensing on the water bottle's side would have less kinetic energy.
Gases have a higher kinetic energy than liquids, despite the fact that liquids have a higher kinetic energy than solids.
Therefore, Evaporation from boiling water causes the particles to move much more quickly than they would in a liquid state.

All of these.
Answers
Glucose has combined with oxygen to make carbon dioxide and Glucose has 6 carbons and has been completely broken down by this stage.
Glucose react with oxygen to make carbon dioxide, water and energy in the form of ATP. Glucose has 6 carbon atoms which react with oxygen that is completely broken down into three products such as carbondioxide, water and energy in the form of ATP by the process of cellular respiration so we can conclude that carbondioxide gas is produced by breaking down of glucose molecules from the Krebs cycle that is a stage of respiration.
