Cattle digest food - methane and carbon dioxide
Animals perform respiration - carbon dioxide
Forest fires burn - carbon dioxide, carbon monoxide, and methane
Plants perform photosynthesis = oxygen
Events and the gas they contributeCattles are able to digest cellulose, fibers, and their likes through the activities of certain bacteria. The process happens through the enteric fermentation of these materials. Thus, carbon dioxide is produced as well as methane.
During respiration, carbohydrates in the form of glucose are broken down to extract the lock-up energy for biological processes. In addition to water, carbon dioxide is also produced as a by-product.
Burning forests leads to the emission of gases like methane, carbon dioxide, and carbon monoxide.
During photosynthesis, inorganic materials are used to synthesize carbohydrates with the by-product being oxygen gas.

The thyroid gland secretes a hormone that increases the body's metabolic rate, breathing rate, and heart rate.
The thyroid gland makes two hormones that it secretes into the bloodstream. One is called thyroxine ,this hormone contains four atoms of iodine and is often called T4. The other is called triiodothyronine, which contains three atoms of iodine and is often called T3. Activation of thyroxine (T4), to the active form, triiodothyronine (T3), by 5′-deiodinase type 2 (D2) is a key mechanism of TH regulation of metabolism.

In common parlance, the term "symmetry" describes a sense of lovely proportion and balance. More exact meaning of "symmetry" can be found in mathematics, where it typically refers to an object that is unaffected by certain transformations like translation, reflection, rotation, or scaling. The development of symmetry Similar to all other characteristics of organisms, symmetry (or asymmetry) develops as a result of natural selection for the organism's benefit. This involves variations in symmetry-related gene frequency across time.
Each object has its own unique pattern and symmetry. Symmetry breaking is viewed by scientists as the process of creating new patterns. In order to categorize unanticipated changes in shape, broken symmetries are crucial. New patterns in nature emerge as a result of symmetry breakdown.

G Proteins are the specialized proteins having the ability to bind GTP and GDP and is of three units called Alpha, Beta and Gamma subunits which together formed G proteins.
When G protein is activated it will bind GTP and each receptor binds in lock and key method and binding result into conformational change which will trigger a complex chain of events influencing different cell function.
Features exhibited by Signal Transduction System are:
1. Specificity- Signal molecules fits binding site on its complementary receptor. Other signal do not fit
2. Amplification- When enzymes activates enzymes, the number of affected molecules increases.

What is an igneous rock?Igenous rocks come straight from the interior of the Earth.
A liquid mass of silicate composition coming from the Earth's core erupts out of a volcano as lava.
Since this melted mass comes from the Earth's interior, its temperature is extremely high.
Lava begins to cool and solidify during its ascent to the Earth's surface.
Igneous rocks are produced by the magma cooling and cristalizing when they get in touch with air.
Thre are two types of igneous rocks
• plutonic rocks ⇒ close to the terrestrial crust ⇒ intrusive ⇒ slow cooling
• volcanic rocks ⇒ on the surface ⇒ extrusive ⇒ quick cooling
Among the options, there are three descriptions that match the igneous rocks,

Gluconeogenesis uses the same enzymatic reactions of glycolysis except for the?
With the exception of the three irreversible events in glycolysis, gluconeogenesis utilizes the same enzyme processes as glycolysis.
Glycolysis & Gluconeogenesis:
In contrast to gluconeogenesis, which is crucial for sustaining blood glucose levels during hunger, glycolysis is a catabolic process that hydrolyzes glucose to produce energy and biosynthetic intermediates.In the catabolic route of glycolysis, glucose is converted to pyruvate. The anabolic route known as glucose conduction produces glucose from non-carbohydrate sources like glycerol and glucogenic peptides. Pyruvate turns into glucose during the process of gluconeogenesis.The general consensus would be that glycolysis and gluconeogenesis don't happen at the same time within similar cells, instead, that metabolic circumstances or allosteric effectors that drive flux along one pathway repress flow in the other direction.Original question:
