Cellular respiration is an exothermic reaction and photosynthesis is an endothermic reaction. How does the required activation energy compare for these two reactions?.
Because the products are at a lower energy level than the reactants, cellular respiration requires less energy to start the reaction.
The activation energy is the bare minimum of energy required for compounds to undergo a chemical reaction. In an exothermic reaction, breaking bonds in the reactants requires less energy than the energy produced when new bonds form in the products. The term "exothermic" literally means "give out heat." Exothermic reactions occur during cellular respiration.
An endothermic reaction, on the other hand, requires more energy to break bonds in the reactants than is released when new bonds form in the products. The term "endothermic" literally means "take up heat." Exothermic reactions occur during cellular respiration.

Looking at a microscope slide under the microscope, you see an E. coli cell, a cork cell, and a mouse cell. Which cell is most likely going to be the smallest?
E. coli
Mouse cell
Elephant cell
Cork cell
Answer:
cork cell I think.... ..
out of the cells of an E. coli cell, a cork cell, and a mouse cell. The E. coli cell is most likely going to be smaller than the mouse and cork cells because these two are eukaryotic cells with lots of organelles. First one is true.
What are the different types of cells?Cells are different types, such as prokaryotic cells, eukaryotic cells, etc., and they are divided on the basis of the nuclear membrane. The prokaryotic cell is comparatively smaller than the eukaryotic cell as these eukaryotic cells have many organelles in them such as the nucleus, mitochondria, etc.
The plant cell is larger than the animal cell because it has an extra cell wall surrounding it, an extra chloroplast, and a large vacuole, all of which eukaryotes lack. Here, the cork cell is a plant cell, so it is the biggest out of all, while the mouse cell is an animal cell, so it comes in second, and the E. coli is the bacterial cell, and it comes in last in terms of cell size.
Hence, the smallest cell is E. coli.

What is the main thing that drives water to move up from roots through the stem or trunk and to the leaves in plants?.
The main thing that drives water to move up from roots through the stem or trunk and to the leaves in plants is evaporation from the leaf pores
As water molecules evaporate from plant leaves, they attract water molecules that remain in the plant, assisting in the water flow from the roots to the stems. The combined effects of capillary action and transpiration transport water from the roots to the leaves of a plant.
Because water molecules tend to grip together (cohesion) and stick to the walls of tubes, they rise from the roots to the leaves (adhesion). The water evaporating from the leaf surface aids the root system's capacity to absorb additional water. This mechanism is known as capillary action.

2. Explain how to focus a microscope using the high power lens. Include any safety issues you need to be
aware of
Answer.
Type your answer her to focus a microscope using the high-power lens you have to use the focus adjustment
knob but be careful because if you crank down too hard you can damage the microscope and the slide
Is my answer right
To focus a magnifier using the high-energy lens you haveto use the main focus adjustment knob however take care as a result of if youcrank down too hard, you'll be able to harm the magnifier and therefore the slide.
Fine Adjustment Knob - This knob is within the coarse adjustment knob and is employed to bring the specimen into sharp focus underneath low power and is employed for all focusing once using high power lenses.You don't wish to wreck the slide. therefore you ought to forever look on the aspect of the magnifier therefore you do not break it and use fin adjustment knob only.

What is the evidence that chiasmata are points of physical exchange between chromatids?.
The evidence that chiasmata are points of physical exchange between chromatids is Cytological markers such as knobs and translocations.
The chiasma is a structure that develops through crossover recombination between a pair of homologous chromosomes and physically connects the homologous chromosomes during meiosis.
Cytological markers are those that are connected to variations in chromosome number, shape, size, and banding pattern. To put it another way, it alludes to the chromosomal banding caused by various stains, such as G banding.
Hence, in chiasmata when the crossing over structure is formed then with the help of cytological markers it can be easily observed and thus it can give physical evidence of exchange and thus these crossing over forms can be easily detected with markers.
