The non spontaneous, anabolic and positive delta E are some of the reaction where net delta G is positive.
What are metabolic reactions?The Gibbs free energy difference between a reaction's products and reactants is known as delta G.
The response is spontaneous if Delta G is negative, non-spontaneous if it is positive, equilibrium if it is zero, and non-spontaneous if it is negative. If dH is positive and dS is negative according to the equation dG = dH - dS*T, then delta G is positive.
Delta G is negative if dH is negative and dS is positive. It depends on the temperature at which the reaction is taking place whether dH and dS are both positive or both negative.
Therefore, The non spontaneous, anabolic and positive delta E are some of the reaction where net delta G is positive.

O C. Mitochondrion
D. Nucleus
The part of the cell which contains the instructions that ribosomes use to assemble proteins is (D) nucleus.
Both prokaryotic as well as the eukaryotic cells has a nucleus, which is where the genetic material DNA is contained and which houses information about the entire structure of the organism.
The ribosomes are instructed by the DNA found in the nucleus to assemble the proteins that the cell needs to survive. These ribosomes construct complex proteins by building constituent parts in accordance with directions provided by the DNA. Translation is the term for the process by which proteins are created from DNA.

1) In 250-300 words describe the light reactions in photosynthesis
2) In 200-250 words describe the dark reactions in photosynthesis
In light reaction it includes the use of light energy for the two molecules. The dark reaction is a light independent reaction.
Describe the light reaction in photosynthesis and also describe the dark reaction in photosynthesis?
Light Reaction:
In light reaction it includes the use of light energy for the two molecules which is needed for the next stage of photosynthesis the energy storage molecule ATP (Adenosine tri phosphate) and the reduced electron carrier NADPH. In plants, the light reactions take place in the thylakoid membranes of organelles called chloroplasts. During the light reaction the chlorophyll absorbs light energy which excites some pigments molecules to higher energy levels.
Dark reaction:
The dark reaction is also called the carbon-fixing reaction. It is a light-independent process in which sugar molecules are formed from carbon dioxide and water molecules. The dark reaction occurs in the stroma of the chloroplast, where they use the products of the light reaction.
So we can conclude that in light reaction it includes the use of light energy for the two molecules. The dark reaction is a light independent reaction.

Define extinction and explain how the fossil record can give evidence of an extinction event.
Answer:
i think it's helpful for you The fossil record, however, describes sudden, global extinctions that affect many species. These dramatic events are known as mass extinctions. Some populations seem more vulnerable than others: tropical forms of life have been drastically affected, while land plants tend to be highly resistant to mass extinctions.hi Mary can we friends ?
Extinction refers to the complete disappearance of a species or group of organisms from the Earth. Extinction can be caused by a variety of factors such as climate change, habitat destruction, competition, predation, disease, and human activities such as hunting and pollution.
Why fossil record is one of the most important sources of evidence?The fossil record is one of the most important sources of evidence for extinction events. When a species goes extinct, its fossils can still be found in the rock record, often in a particular layer of sediment that corresponds to the time period when the extinction occurred.
By studying the fossil record, scientists can identify periods in Earth's history when there was a sudden and widespread disappearance of species, which is known as a mass extinction event.
For example, the fossil record shows that there have been five major mass extinction events in the history of life on Earth, with the most famous being the extinction of the dinosaurs at the end of the Cretaceous period.
The extinction of the dinosaurs is marked by a distinct layer of sediment that contains high levels of iridium, which is rare in Earth's crust but is abundant in asteroids and comets. This layer of sediment suggests that a large asteroid impact may have triggered the extinction of the dinosaurs and many other species.
Overall, the fossil record provides valuable evidence for understanding the history of life on Earth, including the occurrence and causes of extinction events.

An isotonic environment outside a cell has _______% salt, the same as the inside of the cell.
An isotonic environment outside a cell has same amount of salt, the same as the inside of the cell.
What is isotonic solution?Isotonic solutions are the ones that have the similar concentration of water as well as solutes as cell cytoplasm. Because there is no net gain or loss of water, cells in an isotonic solution will neither shrink nor swell.
When a cell is immersed in an isotonic solution, there is no net flow of water into or out of the cell, and the volume of the cell remains constant.
If the concentration of solutes outside the cell is the same as the concentration inside the cell and the solutes cannot cross the membrane, the solution is isotonic to the cell.
Thus, it has same percentage of salt inside and outside.

16. Which of the following geoengineering forms proposes increasing the planet's reflectivity so that more solar radiation is reflected into space?
Intentionally altering the Earth's natural systems on a massive scale to combat climate change is known as geoengineering.
With the use of reflective particles sent purposefully into the upper atmosphere, where they can block the sun's warming rays, solar geoengineering aims to reflect incoming sunlight back into space. First, there is carbon geoengineering, often known as carbon dioxide removal (CDR). The other is solar geoengineering, which is additionally referred to as solar radiation management (SRM), albedo alteration, or sunlight reflection. At least three main categories can be used to classify geoengineering proposals:

c) The potato cube that goes into the 0% water solution weighs 2.78 grams
d) The potato cube that goes into the 0% salt solution weighs 2.78 grams
These are the weights of a potato cube after an experiment of osmosis.
Osmosis is the naturally occurring diffusion or passage of water or other solvents over a semipermeable membrane (one that prevents the passage of solutes, or dissolved compounds). The crucial biological mechanism was initially in-depth investigated in 1877 by German plant physiologist Wilhelm Pfeffer.
Previous researchers had conducted less precise examinations of leaky membranes (such as animal bladders) and the transport of water and escape chemicals through them in opposite directions. Thomas Graham, a British chemist, coined the term "osmose," which is still used to refer to the process, in 1854. A solution will tend to become more diluted by absorbing solvent through a membrane separating it from the pure solvent if the membrane is permeable to the solvent but not to the solute.

Do plants die becuase of too much sun or too much water??
Answer:
They can die from both
Explanation:
Plants need sun but too much sun can dehydrate or damage the plant. As if too water plants need air too breath so adding too much water can drown them
Answer:
Both
Explanation:
Plants harvest energy from the sun with the help of chlorophyll and carotenoid, two photon-capturing molecules. But if the plants are exposed to too much sun, these molecules absorb more energy than they can handle and generate reactive species of oxygen that can destroy the plant.

Roots growing in waterlogged soil may die because they cannot absorb the oxygen needed to function normally. The longer the air is cut off, the greater the root damage. The dying roots decay and cannot supply the plants with nutrients and water. Damage caused by over watering is frequently misdiagnosed as pest damage.
