Use the following graph of two theoretical populations (species A and B) to answer the following questions:
avanturin [10]
A) This is predator-prey relationship.

B) Species A is prey and species B is predator.
- If prey population decreases in number, the predator population will also decrease because there is not enough food for predators to survive and vice versa.

- If predator population decreases, the prey population will increase because less prey will be eaten by predators and vice versa.


C) Let population A be Zebras, and population B Lions.

From the graph, at the beginning the there is increase in Lions, as well as in smaller rate in Zebras. At one point, the population of Lions begins to decrease, so they will eat less Zebras. This will allow Zebras to increase population. With more Zebras on the menu, more Lions will eat and increase their chance to survive. This leads to decrease in Zebra population. But again, with less Zebras, the Lion population must decrease allowing Zebra population to increase, and so on.

To amplify and express a gene of interest, it must first be cut out of the chromosomal DNA and inserted into what? A) restrictio
Papessa [141]

The right answer is C) vector

In molecular biology and genetic engineering, vectors are DNA molecules that allow the propagation of sequences of interest. These are chimeric DNA molecules such as plasmids or artificial bacterial chromosomes, containing an origin of replication and one or more genetic markers. The origin of replication allows the maintenance of the vector in the target cell during generations.

How do living things make use of the energy stored in food molecules?
ipn [44]
Answer:
             The energy stored in food molecule (glucose) is released in he process of respiration. 

Explanation:                     Respiration is a cellular process in which glucose molecule is broken down into carbon dioxide, water and ATP is produced as end product. Respiration consists of following main steps:
1. Glycolysis:                It occurs in the cytoplasm of cell, and each glucose molecule is converted into two pyruvates with help of ATP.
2. Formation of Acetyl coenzyme A:                                                        It is a connecting link reaction between glycolysis and Kreb cycle. In this phase Each pyruvate react with Coenzyme A to become acetyl coenzyme A.
3. Kreb Cycle:                   It occurs inside mitochondria. In this cycle each acetyl coenzyme A with fixed with CO to produce citrate which undergo in a cyclic reaction to produce ATP and NADH. . 
4. Electron transport chain:                                           It is the last step of respiration which complete in mitochondrial membrane. In this phase most of the energy is produced along with H₂O as by product.
