are the components for the activation of a helper t cell by a dendritic cell.
Answer:
The correct option will be Option B (study only physical aspect of primates).
Explanation:
- The significant components of that same endangered as well as surviving primates are analyzed by a primatologist. Also, the primates come to terms with either the molecular and physiological elements.
- A primer broader knows a great deal about everything from the bones of the primates. We also integrated depth of understanding of both biologizes including primate behavior.
The other choices don't apply to the specified scenario. So option B will be the perfect option for b.
Answer:
Different from one another.
Explanation:
Both rocks are different from one another because one rock is formed from small pieces of rock while the other is made of liquid rock. Due to formation from different types of materials both rocks are different from one another. If both rocks are formed from small pieces of rock or liquid rock, then we can say that both rocks are similar to each other in composition.

Question: Select the correct statement about the special fetal blood vessels.
A The umbilical vein becomes the ligamentum teres.
B The distal parts of the umbilical arteries form the superior vesical arteries.
C The hepatic portal vein forms from the umbilical artery.
D The fossa ovalis becomes the f
oramen ovale.
Answer:
C) The umbilical vein becomes the ligamentum teres.
Explanation:
After birth, many vascular changes occur in the newborn child as the pulmonary, renal and digestive systems start functioning. As the umbilical cord is tied off and severed, the blood does not flow through the umbilical arteries. The umbilical vein in the child collapses but remains as the ligamentum teres. Ligamentum teres is a round ligament and serves to attach the umbilicus to the liver. It is present in the free border of the falciform ligament of the liver.
