Answer:
point mutation, change within a gene in which one base pair in the DNA sequence is altered. Point mutations are frequently the result of mistakes made during DNA replication, although modification of DNA, such as through exposure to X-rays or to ultraviolet radiation, also can induce point mutations
Answer: Gastrocholic reflex
Explanation:
The gastrocholic reflex or gastrocolic response is one of the physiological reflexes in the stomach which controls the movements like peristalsis and motility in the gastrointestinal tract.
This reflex is generated by the the food particles that enters the stomach. The bolus of the food in the stomach helps in the mass movement of the other food particles in the colon.
This reflex is known as gastrocholic reflex.
I’m confused of the question your asking,can you give me more details?
the mitochondrion is where it takes place
Answer:
The correct option is A
Explanation:
To determine if water temperature has an effect on weathering of sedimentary rocks, different number (perhaps three) of identical sedimentary rocks should be obtained and then individually placed in different water temperatures (with at least one of the "water volumes" used for each having a temperature close to the room temperature so as to be used as the control).
Thus, each of the identical sedimentary rock can be broken into three and placed individually; as in one part of the rock in 20 °C of water (control), another part of the rock in 40 °C and another in 60 °C of water.
This above procedure should be repeated for the remaining two other identical sedimentary rock to confirm if there is any effect.
