The statement "All organisms appeared on Earth at the same time and remained unchanged throughout history." is just a saying, it does not have any scientific evidence.
And in above option,
'A' shows about scienticific data but there is no any science in statement.
'C' shows Mendel's work with pea plant which is a scientific experiment.
'D' shows Lamarck's idea which is also based ob science.
Therefore, the answer is religious beliefs
(Carnivorous) They don't rely as much on the mechanical breakdown of foods in the mouth as much as they usually eat their prey whole. They also have U-shaped stomachs.
They regurgitate indigestible things (e.g. Large Bones)
They have shorter, spiralling intestines, but this means it also has a large surface area.
Solution:
4.2 x 10^6 bp/10^3 bp/seconds = 4.2 + 103 s which is 4200 seconds and equivalents to 70 minutes
In addition, assuming a pause of 2 seconds for re initiating after completing every okazaki fragment and assuming the okazaki fragments average 1000 nucleotide long.
4.2 x 10^6 bp/10^3 bp = 4200 okazaki fragments 4200 * 2 seconds = 8400 seconds which is 140 minutes or 2 hours 20 minutes of pauses alone.
Therefore, overall time would be pauses plus the 70 minutes so total time of 210 minutes. Assuming that the replisome completely disassociates from the DNA after every okazaki fragment and must spend one-minute rebinding.
4200 okazaki fragments. 60 seconds rebinding time per fragment: 4200 x 1 minute = 4200 minutes rebinding time plus 70 minutes for actual replication. 4200 minutes is 70 hours which is almost 3 days.
Answer:
The entry of food into the stomach.
Explanation:
Gastric secretion is triggered by the act of eating which is called as reflex phase and the entry of food into the stomach called a gastric phase. The entry of the food particles into the small intestine also helps to control the secretion of gastric called an intestinal phase.
The secreted fluid in the small intestine contains some ions, acids, etc such as pepsinogen, intrinsic factor, bicarbonate, hydrochloric acid, and mucus. The reflex phase or cephalic phase helps to stimulate parasympathetic neurons that release acetylcholine chemical, then it produces the higher secretion of gastric juice.
