Regeneration in planarians depends on the presence of stem cells called neoblasts. These cells are distributed throughout the body and, when part of the worm has been amputated, they are activated to reform the tissues that have been removed.
Answer:
carbon, hydrogen, oxygen, and nitrogen (CHON). Nucleic acids such as DNA and RNA contain carbon, hydrogen, oxygen, nitrogen, and phosphorus (CHON P).
Explanation:
A chicken provides protein and therefore the chicken will have the molecules present in a protein
Answer and explanation;
-The insulin receptor itself has decreased kinase activity leading to fewer binding sites for singling effectors to become activated.
Therefore; the signaling effectors are less likely to be activated.
-Additionally,, feedback inhibition decreases signaling effector binding to receptor.
-The lack of activation of these initial signaling effectors prevents any subsequent steps from happening.
-We can thus conclude this by saying that higher insulin concentrations are necessary to obtain the same level of signaling leading to physiological effects that would exist in someone without type-2 diabetes.
-Also the requirement for higher insulin concentration means that the cells that respond to insulin are resistant to its effect.
Answer:
When ocean salt water evaporates, the salt in the water is left in the water. This causes the salt water to become heavily filled with salt.
