Answer:
Afferent arterioles are a group of blood vessels that supply blood to glomerulus in nephron while afferent arteriole brings back blood from glomerolus.
Answer:
Explanation:During fertilization the embryo receives half of its genetic information from both parents. If one parent is a carrier or sickle cell their genes would be Aa little a being the recessive gene. When mixed with the other parents gene who does not have sickle cell their genes would be AA. When you make a pun net square the results would be AA,AA,Aa,and Aa. Therefore the offspring would have a 50% chance of being a carrier of sickle cell but not having the actual disease
Answer:
Gap junctions.
Explanation:
Gap junctions may be defined as the intercellular connection present between the cells of the animals. They are made of the connexons and present in all cells of the body except skeletal muscles.
The small molecules and ions can easily pass through the gap junctions. The neighbouring cells can pass the molecules and communicates with each other through the gap junctions. They are known as macula communicans. Invertebrates have the gap junction made of innexin.
Thus, the answer is gap junctions.
