Explanation:
There are a number of ways to produce hydrogen: Natural Gas Reforming/Gasification: Synthesis gas, a mixture of hydrogen, carbon monoxide, and a small amount of carbon dioxide, is created by reacting natural gas with high-temperature steam. The carbon monoxide is reacted with water to produce additional hydrogen.
As of 2020, the majority of hydrogen (∼95%) is produced from fossil fuels by steam reforming of natural gas, partial oxidation of methane, and coal gasification. Other methods of hydrogen production include biomass gasification and electrolysis of water.
Answer:
Explanation:
Cellular respiration is a process which occurs in the all living cell all the time. It is an oxidative process by which respiratory substrate such as glucose (C₆H₁₂O₆) is oxidised completely in presence of oxygen(O₂) to produce carbon dioxide (CO₂), water and energy in the from of ATP. ATP is is the energy currency of the cell. The process of cellular respiration begins in cytoplasm and completes in the mitochondria of the cell.
The overall reaction of respiration is given below:
C₆H₁₂O₆+ 6O₂ → 6CO₂+ 6H₂O + Energy (ATP)
Answer:
A blood clot
Explanation:
It is formed to stop bleeding and foreign bodies from entering the body.
Answer:
Root hair cells are alive and therefore need energy, which is why root hair cells contain many mitochondria in them. Root hair cells don't contain chloroplasts. Chloroplasts are used by the plant to make food using light energy. Since the roots aren't exposed to any form of light, they have no need for chloroplasts.
Nondisjunction is most likely responsible for the failure of a gamete to receive a copy of a particular chromosome.
What is non-disjunction?
When a pair of homologous chromosomes fails to segregate or separate at anaphase, both of the pair's chromosomes pass to the same daughter cell. This most likely happens during meiosis, but it can also happen during mitosis to create a mosaic individual. These are some potential causes of nondisjunction, while the exact cause or causes are unknown. Growing maternal age is linked to trisomy 21 and trisomy 18 fetuses and newborns, indicating that the mother's age may be a significant etiological component. Chromosomal structural defects such translocations and pericentric inversions might hinder chromosome pairing during meiosis and encourage nondisjunction.
