Answer :
B.) they orbit the sun
Answer: hydrolysis of intermediate palmitoyl Co A ,with loss of labeled CoA.before reaching the matrix gives the answer
Explanation:
This is because when the labeled Coenzyme A of the Plamitate combines as Palmitoy-CoA with oxaloacetate to form intermediate (palmitoyl-CoA )in Citric Acid cycle:
CoA is hydrolysed with loss of the labelled CoA which returns to the cystosol. Therefore, the labelled CoA does not reach the matrix of the mitochondrial,but returns to the Cystosol.
Consequently, the CoA in the Cystosol will be labelled in palmitoylCoA and the one in the matrix of the liver mitochondrial will be non radioactive(,will not labelled).
Answer:
DNA, RNA, Proteins, the genetic code, ribosomes, phospholipid membranes, DNA polymerase for DNA replication, RNA polymerase, ATP-ase (=ATP synthase).
Explanation:
Reductive Citric Acid Cycle is not present in the anaerobic organisms.
Answer:
the oxygen concentration decreases only when the air reaches the alveoli, which are the terminal branches of the respiratory system
Explanation:
The human respiratory system is responsible for taking in oxygen-rich air, and they expelling oxygen-poor air. The respiratory system consists of lungs, which helps in the exchange of gases: Oxygen and carbon dioxide.
The statement ''the oxygen concentration decreases only when the air reaches the alveoli, which are the terminal branches of the respiratory system'' explains the change in oxygen concentration of the inspired air
1. fossils and chemical isotopes found in sediments and glacial ice
By studying the type of climate fossilized species preferred global temperature trends can be inferred. The changes in the concentration and type of isotopes are also an accurate measurement tool of these changes.
2. decrease in mortality because winter is warmer
The phenomenon known as global warming will bring more extreme weather. Thus, it is possible for some winters to be very cold and summers be very warm.
Even with warmer winters, the mortality will not decrease. Without a snow cover, pests such as mosquitoes and pathogens will thrive and live for longer periods of time. Thus, the spread of diseases will increase which will lead to potential increases in mortality.
3. all activities by humans affecting the Earth and its biosphere
Anthropogenic activities are all activities by humans affecting the Earth and its biosphere.
4. decline in sea ice
The main cause behind declining numbers of polar bears is the diminishing size of the sea ice. The bears use the ice as hunting ground where they stalk seals.
