Answer:
The correct answer is C in presence of oxygen production of acetyl CoA,TCA cycle and electron transport chain occur in a proper order.Whether in absence of oxygen lactic acid fermentation or alcoholic fermentation occurs.
Explanation:
Aerobic respiration occur in presence of oxygen which involves glycolysis,TCA cycle and electron transport chain.Aerobic respiration result in the catabolism of glucose to generate CO2,H2O and ATP.
But in absence of oxygen or during anaerobic condition pyruvic acid is converted to either lactic acid by pyruvate dehydrogenase or to ethanol through alcoholic fermentation.
The theory of Natural Selection was accepted after it got consensus from
scientists.
<h3>What is natural selection?</h3>
The theory of Natural selection defines the process in which individuals who adapts to their environment survives and reproduce more offspring.
- This theory was proposed by a scientist called Charles Darwin and Alfred Russel Wallace who also had the idea of evolution.
- This two scientist work together to publish a book on new evolutionary theory titled On the Origin of Species (1859). This is because they believed evolution occur through natural selection.
In this theory, organisms produce offspring but not all offspring survive this because they all struggle to live.
survival is based on survival of the fittest. some of those who survive can reproduce their kind while some do not grow to maturity and are loss.
Therefore, The theory of Natural Selection was accepted after it got consensus from scientists.

Answer:
a. histones. is the correct answer.
Explanation:
In a nucleosome, the DNA is wrapped around eight histones proteins to create strong loops termed nucleosome.
A nucleosome is the structural subunit of the chromatin.
Chromatin is a fiber polymer of double-stranded DNA which is composed up of a nucleosome core. The nucleosome core is made of histone proteins
Each nucleosome is composed of DNA enclosed around eight histone proteins which are called histone octamer.
Answer:
weathering occurs when rocks sit in a pool of salt water. weathering or eroding
Explanation:
<span>Earth consists of four major layers: the crust, mantle, outer core and inner core. While most of the layers are made of solid material, there are several pieces of evidence suggesting that the outer core is indeed liquid. Density, seismic-wave data and Earth’s magnetic field provide insight into not only the structure but also the composition of Earth’s core</span>
