Answer:
Bulbus arteriosus
Explanation:
The heart of a fish is a two-chambered organ which works in a single cyclic way but the heart also has the entrance and exit organs.
The deoxygenated blood from the body of the fish is first collected in an entrance structure called sinus venosus from where the blood enters the atrium. The atrium passes its blood to the ventricle and before out of the heart, the blood is collected in a chamber called the Bulbus arteriosus.
The Bulbus arteriosus is a pear-shaped organ which maintains the flow of the blood to the gill in the fish.
Thus, Bulbus arteriosus is correct.

The first one is 2, The answer to question 2 would be: <span>gene splicing or cloning
First, the gene that makes insulin is cut from human cells. After having the insulin gene, the scientist will put it inside bacteria so the bacteria will produce human insulin. </span>This was called gene splicing.
Then the bacteria have insulin genes, the bacteria will be cloned to make multiple colonies of same bacteria. This phase called cloning.
and the last one 2, mitochondria.
The right options are;
A.The population of pink katydids will decrease.
B.The population of green katydids will decrease.
What will eventually happen to the population of the katydids is that the population of both the pink and green katydids will decrease. The predators which are the birds that feeds on the katydids (prey) will negatively influence the size of the prey populations by reducing them.
