Where does the oxygen used in cellular respiration end up?
xz_007 [3.2K]

Oxygen used in cellular respiration ends up in ATP Synthesis in Oxidative Phosphorylation.

Explanation:

Since oxygen is the last electron acceptor in Electron transfer chain, the H ions flow through ATP synthase for ATP synthesis. The electrons from the NADH and FADH are pumped from the matrix of mitochondria to inter-membrane space. The energy released due to the proton gradient formed is used for making ATP.

In your own words, describe the purpose and process of translation. The purpose of translation is… The process of translation is
kondaur [170]

Answer:

the purpose of the translation is to make proteins. proteins are responsible for making bones, muscles, cartilage, skin and blood. proteins are synthesized from the information in a mRNA.

Process of translation

it happens in 3 phases

  • initiation: the small ribosomal subunits binds to the start of the of the mRNA sequence. then a tRNA molecule carrying the amino acid methoionine binds to start codon of the mRNA sequence. after that large ribosomal subunit binds to form the complete intiation complex.
  • elongation: the ribosome continues to translate each codon in turn each corresponding amino acid is added to the growing chain and linked via bond called peptide bond. elongation continues untill all the codons are read.
  • termination: it occurs when the ribosome reaches a stop codon. since there is no tRNA molecules that can recognise these codons the ribosome recognises that translation is complete.

after these 3 phases a new protein is realeasd

Which shot angle rarely results in a clean kill, ruins a lot of meat, and provides an animal the best opportunity to detect the
iogann1982 [59]

Answer:

The correct answer is option d) "head-on".

Explanation:

In hunting, the head-on angle refers to a position at which the hunter and the prey are face to face. This shot angle rarely results in a clean kill, ruins a lot of meat, and provides an animal the best opportunity to detect the hunter as the animal is in front of the hunter. At the head-on angle it is harder for the hunter to kill an animal with the first shot and ruins a lot of meat because the animal produces hormones such as adrenaline result of the stress.

In a certain species of plant, the allele to produce green melons (G) is dominant over the allele to produce yellow melons (g).
marishachu [46]

Answer:

4.26

Explanation:

Let the green-melon parents be Gg, then we expect the cross with the yellow-melon plant gg so as to produce 50% Gg and other 50% of gg offspring. What we observed was that 53 green and a 41 yellow. Based on the total number of 94 offspring , we expected half and a half ratios to be 47 of each color.

                                Observed(o)   Expected(e)   (o-e)    $(o-e)^2$      $(o-e)^2/e$

Green-melon plant        53                    47               6          36             0.766

Yellow-melon plant        41                    47              -6          36             0.766

Therefore the chi-square value is 1.53 which is less than the critical value of 3.84. Therefore, the null hypothesis is accepted.

Explain how an organism's circulatory, digestive, or excretory system helps the organism maintain homeostasis
choli [55]
Circulatory - 
Brings oxygen and nutrients where it is needed, removes toxic chemicals, maintains a stable body temperature

Digestive -
Food and nutrients are absorbed in the small intestine. These nutrients are necessary for other body systems to maintain homeostasis. 

Excretory - 
Removes all waste from the body, kidneys filter chemicals, liver filters toxins
