Answer:
Aerobic respiration is the process or set of cycles that producing cellular energy with the help of oxygen. In this process cells, breakdown glucose in the multi-step process in which the very first step is glycolysis, the second is the Krebs's cycle and the third is the electron transport system in the mitochondria.
<u>Glycolysis</u>: It is the first step of cellular respiration that is enzyme based metabolic reaction that converts glucose into pyruvate and releases energy in the form of ATP and NADH. The net gain of the pathway is two ATP and two NADH.
Pyruvate oxidative link is an intermediate reaction between glycolysis and Krebs cycle that converts pyruvate to acetyl CoA.
<u>Krebs cycle:</u> It is a pathway involves chemical reactions release stored energy through the oxidation of acetyl CoA derived from pyruvate into adenosine triphosphate and carbon dioxide.
<u>Electron transport system:</u> all previous steps reduce the electron carriers to NADH + H+ and FADH2. Then these donate protons and electrons to the electron carrier proteins of the ETS system. In the end, the electron accepted by oxygen.

Explanation:
DescriptionA biological system is a complex network of biologically relevant entities. Biological organization spans several scales and are determined based different structures depending on what the system is. Examples of biological systems at the macro scale are populations of organisms.
The answer it’s D I hope ugly it right and good luck with ur test
Answer:
Phenotypic ratio= 1:1
Genotypic ratio = 1:1
Explanation:
This is a monohybrid cross involving a single gene that specifies a color phenotype.
According to the question, WW, which is homozygous dominant i.e same allele is white while ww, which is homozygous recessive is black.
Hence a genotype Ww will possess a white phenotype since the W allele will mask the expression of w.
In a cross between a female and male with a a Genotype Ww and ww respectively. The parents alleles will be separated into gametes according to Mendel's law of segregation. (See attached image).
Ww will produce gametes W and w
ww will produce gametes w and w
The four possible offsprings will have Ww (2) and ww (2) genotypes. Hence two of them will be white while two will be black.
Hence, the phenotypic ratio will be 1:1 while the genotypic ratio will also be 1 Ww: 1 ww
