Answer:
2 ATP molecules.
Explanation:
This question is describing KREB'S CYCLE, which is the second stage of aerobic cellular respiration that occurs in the mitochondrion. In the Kreb's cycle, also known as tricarboxylic acid cycle, pyruvic acid (product of glycolysis) is oxidized to produce NADH, FADH2, ATP and CO2 as products.
In a nutshell, per glucose molecule that begins the respiration process (glycolysis), 2 molecules of ATP are produced alongside 3 NADH and 1 FADH2 molecules in the Krebs cycle. Note that, the electron carriers (NADH and FADH2) are used in the electron transport chain.
Answer:
a. Viral infections may lead to inflammation between the ribs (i.e., costochondritis)
b. Viral infection
c. Viral infection may lead to the influx of chemical mediators (cytokines), increased blood flow, and movement of plasma and white blood cells (leukocytes) from the blood into the injured site
Explanation:
Costochondritis is a painful condition caused by the inflammation of the cartilage that joins the ribs to the breastbone (this joint is known as the “costochondral joint”). Costochondritis is caused by inflammation of the costochondral joint, which may be triggered by multiple causes including, among others, viral/bacterial/fungal infections, exercise or strenuous activity, chest trauma, osteoarthritis, presence of tumors, etc. Acute inflammation is the immediate immune response of the body to harmful stimuli (e.g., viral infections), which is characterized by the increased movement of white blood cells (such as neutrophils and macrophages) that rapidly travel from the blood into the injured area. This plasma contains chemical mediators like pro-inflammatory cytokines which are secreted from immune cells (e.g., Th1 cells, CD4+ cells, macrophages) in order to promote inflammation.
Humans have a density close to 1000 kg/m³ (the density of water). If a human has a mass of 75 kg, the volume would be around 0.075 m³.
<u>Answer</u>: Formation of a fossil.
<u>Explanation</u>:
- The fossils are formed when an organism dies and gets preserved due to some conditions.
- Since all living organisms contain a certain amount of carbon in their body when they die and, their fossil is formed the carbon present in the living organisms gets stored in the fossil as well.
- An example is the carbon film fossil which is formed due to the carbon residues left behind of soft-bodied organisms after they die.
