Answer:
When molecular hydrogen (H2) and oxygen (O2) are combined and allowed to react together, energy is released and the molecules of hydrogen and oxygen can combine to form either water or hydrogen peroxide. In this oxidation, a molecule of hydrogen gas is ionized to two electrons and two protons
During binary fission in a bacterial cell, a base pair is changed from adenine to cytosine due to a random mutation.
Binary fission is a type of asexual reproduction through which a bacteria divides and its body is separated into two new bodies.
If during binary fission in a bacterial cell, a base pair is changed from adenine to cytosine, it is because of a random mutation. A mutation is a genetic alteration or a change in the DNA sequence which results in the generation of a variant. Mutations in the DNA sequence which occur without any specific pattern is known as a random mutation.

He needs to be careful to document his sources about the problem of invasive species.
<h3>What is Invasive species?</h3>
- An introduced organism that overpopulates and damages its new environment is referred to as an invasive species.
- Even though the majority of introduced species are neutral or helpful to other species, invasive species have a negative impact on habitats and bioregions, harming their ecology, the environment, and/or their economy.
- Invasive species are one of the largest issues our natural environments have ever faced.
- Invasive species have the potential to proliferate rapidly in the absence of their natural predators, displacing native species, destroying ecosystems, and incurring high costs.
- This increase is frequently attributed to growing global trade, manufacturing specialization, and linkages to previously remote areas.
- Additionally, the extension of existing imported specie's ranges is made possible by climate change.

Answer:
parathyroidoma
Explanation:
The condition where the parathyroid hormone is produces excessively is termed as Hyperparathyroidism. This condition arises when the balance between the calcium and phosphorus gets disturbed. The calcium and phosphorus balance is affected in following two cases –
a) When the parathyroid gland is not working properly due to its own problem usually termed as hyperparathyroidism or more specifically primary hyperparathyroidism
b) When the parathyroid gland is not working properly due to any other disease in the body affecting the functioning of parathyroid. It is termed as secondary hyperparathyroidism
