Hydrogen-oxidizing bacteria are the members of gram-negative bacteria, metabolism involves using hydrogen as an electron source and oxygen as a terminal electron acceptor, hence forming water.
Gram-negative genera Aquifex and hydrogenobacter stand for "water-maker" to indicate hydrogen oxidation and terminal electron transfer to oxygen. They are chemoautotrophs, that share the ability to oxidize H₂ and fix CO₂ to provide energy and synthesize cellular material. Applicatated for resource recovery and pollution removal.
They are known to grow at the highest temperature and grow usually at neutral or slightly acidic pH. These microorganisms use CO₂ assimilation pathways. They are metabolically versatile chemolithoautotrophs, using reductive tricarboxylic acid (rTCA) cycle.

Answer:
Feedback inhibition is also necessary to prevent enzymes from breaking down too many molecules that are energy sources for the cell, such as glucose. Inhibition takes place in glycolysis, the process of breaking down the sugar glucose to produce the cell's "energy currency" molecule ATP.
<span>Summer temperatures in the Arctic remain cool, fluttering around zero in many places, from June through September. In fact, Arctic residents must frequently heat their homes all year long. Neighbourhoods near the sea tend to remain close to 0°C throughout the summer, but inland areas, particularly in the south, regularly reach 7°C–13°C, and hardly as much as 20°C. One reason for the opposition is that the sea ice, which gradually melts, consumes much of the sun's energy, giving little to heat the air over it.

Answer:
A. inheritance and reproduction
Explanation:
These two terms are interrelated as the act of one (reproduction) gives rise to the other (inheritance). The process whereby offsprings are produced using gametes (sexual reproduction) or without gametes (asexual reproduction) from a an organism called the parent is called REPRODUCTION. Reproduction is necessary to ensure the survival of a particular species.
During reproduction, the genetic material (DNA) in form of chromosomes of an organism is passed down from parents to offsprings in a process called INHERITANCE or HEREDITY. The information needed for certain processes like growth, reproduction, survival and others are contained in the genetic material, and are transferred from the parents to their progenies.
In sexual reproduction, this biological information encoded in the genetic material is passed on via gametes produced by each parent (male and female) during meiosis.
Answer:
<u>23</u> chromosomes
Explanation:
Each daughter cell <u>will have half of the original 46 chromosomes</u>, or 23 chromosomes. Each chromosome consists of 2 sister chromatids. The daughter cells now move in to the third and final phase of meiosis: meiosis II.
