Cellular respiration is an exothermic reaction and photosynthesis is an endothermic reaction. How does the required activation energy compare for these two reactions?.

Answers

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.

The term "big data" first appeared in the early 2010s, and it is now understood that these features are what caused the field of study, analysis, and applications to take off.

Feature selection plays a crucial function in assisting in the reduction of high-dimensionality in machine learning problems in an era of increasing data complexity and volume as well as the emergence of big data. We go over the history and significance of feature selection as well as contemporary developments in a variety of fields, such as DNA microarray analysis and face recognition. Huge datasets have been created in recent years, and it is obvious that their size and number will only increase. As a result of the growing need for scalable yet effective feature selection methods due to the likelihood that current methods will be insufficient, this new big data environment presents feature selection researchers with both opportunities and challenges.

What is the evidence that chiasmata are points of physical exchange between chromatids?.

Answers

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.

What is the main thing that drives water to move up from roots through the stem or trunk and to the leaves in plants?.

Answers

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.

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.
