Photosynthesis is an endothermic process in which carbon dioxide is fixed into glucose using sunlight, and oxygen is released. Cellular respiration is an exothermic process in which the glucose is oxidized back into carbon dioxide, releasing stored energy as ATP.
Photosynthesis is an endothermic process in which carbon is fixed, whereas cellular respiration is an exothermic process in which carbon is oxidized. In photosynthesis, green plants convert carbon dioxide and water into glucose and oxygen, using sunlight as the energy source. The chemical formula for this process is 6CO2 + 6H2O --(in the presence of sunlight)--> C6H12O6 + 6O2. This process not only creates glucose, which plants use as 'food,' but also contributes vital oxygen to the atmosphere, essential for animal life.
On the other hand, cellular respiration is how cells convert the stored chemical energy within glucose into usable energy called ATP (adenosine triphosphate). During this process, oxygen is used to break down glucose, which results in the production of carbon dioxide and water as waste products, releasing energy in the process.

Why did redi carry out another experiment with three jars?
Francesco Redi performed an experiment with three jars to disprove the theory of spontaneous generation by showing that maggots did not randomly appear but were born of flies' eggs.
Explanation:Francesco Redi was a 17th century Italian physician who conducted an experiment with three jars to disprove the then-prevalent theory of spontaneous generation, which claimed that living organisms could arise from non-living matter. Each jar had meat in it. The first jar was left open, the second was covered with gauze, and the third was sealed. Flies were able to lay eggs on the meat in the open jar, resulting to maggots. For the second jar, flies were attracted to the meat but were unable to reach it due to the gauze, hence no maggots were found. And for the sealed jar, there were no flies nor maggots observed. This experiment established that the maggots did not spontaneously appear but were born of the flies' eggs.

A person who is homozygous for the x chromosome is
Final answer:
A person homozygous for the X chromosome has two X chromosomes (XX) and is biologically female, in contrast to males who are heterozygous (XY). This is a basic principle of mammalian sex determination.
Explanation:
A person who is homozygous for the X chromosome possesses two copies of the X chromosome (XX) and is biologically female. This genetic configuration differs from males who are heterozygous with one X and one Y chromosome (XY), leading to male characteristics. In the context of sex determination, being homozygous for the X chromosome means that the individual will develop female characteristics, as the absence of a Y chromosome does not trigger the development of male traits. This is a fundamental aspect of mammalian sex determination, which follows the XY system, also found in some insects and plants.

Why is there controversy to the opinion that human contribution of carbon dioxide to the atmosphere is causing global warming?
choose the answers that best fit
Because the Earth goes through periodic cycles of cooling and warming.
Because the levels of carbon dioxide being released by humans has not increased since the past.
Because climate is so complex that the two cannot be definitively related.
Because the statistics are not clear about how much additional carbon dioxide input would be required to raise global temperatures.
Answer: Because the statistics are not clear about how much additional carbon dioxide input would be required to raise global temperatures.
Explanation:
Global warming can be define as the increase in temperature worldwide due to increase in abundance of greenhouse gases in the atmosphere. These gases are responsible for trapping the heat energy from sunlight.
Carbon dioxide is also a greenhouse gas which is chiefly responsible for global warming. There is a controversy that human beings are responsible for global warming as release of carbon dioxide into the atmosphere is due to burning of fossil fuels and deforestation on the large scale. But volcanic eruption and other natural factors are also responsible for such increase in abundance. Therefore, a proper statistical account for release of carbon dioxide in the environment has not been framed.

Trigeminal motor neurons found in the brain cell helps in moving the muscles but during REM sleep, the two neurotransmitter receptors namely GABAA and glycine are paralysed by the brain stem and hence no muscle activity could be observed during the REM sleep
Zooplankton eat algae. this is an example of a feeding stage or _____.
Final answer:
Zooplankton consuming algae exemplifies the primary consumer role in a food web. As primary consumers, zooplankton feed on primary producers like phytoplankton, situating them at trophic level 2 in aquatic ecosystems.
Explanation:
Zooplankton eating algae is an example of a feeding stage called the primary consumer level in a food web. Phytoplankton are primary producers that utilize photosynthesis to create energy and serve as the base of the aquatic food web. Zooplankton, which are considered herbivores in this context, feed on these phytoplankton. This interaction illustrates one of the many energy transfer steps within a food chain.
Within a food web, different organisms occupy various trophic levels based on their source of food. Zooplankton would be at trophic level 2 as primary consumers when they exclusively eat phytoplankton.

What is the biochemical basis for the spectrum of fastidiousness seen in the microbial world?
Final answer:
The biochemical basis for microbial fastidiousness is due to the diverse metabolic needs and tolerances of microorganisms, necessitating specific growth factors and environmental conditions that can be hard to replicate in a lab. Biochemical profiling and advanced technologies like MALDI-TOF mass spectrometry are used for identification, but newer approaches like oligotyping offer more nuanced insight into microbial diversity.
Explanation:
The biochemical basis for the spectrum of fastidiousness in the microbial world is rooted in the diverse array of microbial physiological requirements and metabolic capabilities. Organisms vary in their need for specific nutrients, tolerance to environmental stressors, and the complexity of their energy-producing biochemistry. For instance, fastidious microorganisms may require very particular growth factors or conditions that are difficult to replicate in a laboratory setting. These organisms are often studied using metagenomic sequencing and bioinformatic tools, which bypass the need for culturing and allow for a more accurate representation of microbial diversity.
In terms of identification, a foundational method is the creation of a biochemical profile through assays that reveal the presence of certain metabolic intermediates or end products. Biochemical assays provide clues to an organism's identity and may require stringent conditions reflective of an organism's native habitat. Advanced technologies like MALDI-TOF mass spectrometry further enable rapid identification based on mass spectral fingerprints of bacterial proteins. However, generating accurate results using culture-dependent identification methods may be subject to biases against slower-growing or more fastidious organisms. Techniques such as oligotyping can overcome some of these challenges by providing highly resolved taxonomic categorization.
