Answer:
The correct answer is:
population of the predator species is larger and the populations of the prey species are smaller. (C)
Explanation:
apparent competition occurs occurs between two species or group of organisms that do not directly compete for resources affect each other indirectly by being prey to the same predator. For example consider three species of organisms; sparrows, earthworms and beetles, where earthworms and beetles are preys of the sparrows, an increase in the population of earthworms will in the long term lead to an increase in the population of sparrows, which means that more predators will be available, leading to a decrease in the population of beetles, because more predators are available to prey on them. Also a decrease in the population of earthworms will also lead to a decrease in the population of beetles because their probability of being seen by the predators will increase leading to an increase in their killing.
Therefore in apparent competition, although it occurs between two prey species, their in an increase in the number of predators and a decrease in the population of the prey.
Answer:
The correct answer is 2. "the child needs these pancreatic enzymes to help the digestive system absorb fats, carbohydrates, and proteins".
Explanation:
90% of patients with cystic fibrosis get the pancreatic enzymes supplement because of their pancreatic insufficiency. These enzymes are released in the intestine and help to digest food.
The enzymes´ principal functions are:
- To digest carbohydrates, proteins, and fats;
- To help to gain weight;
- To promote the absorption of nutrients.
To get an appropriate corporal weight and an improved lungs´ functioning it is important to take the enzyme supplement with every meal. It reduces bad absorption and improves nutrition.
The correct answer is: Replacement of defective genes with normal genes
Recombinant DNA molecules are made in laboratory by the methods of genetic recombination such as molecular cloning. The aim of these methods is to bring together genetic material from different sources, creating “combinations” that usually couldn’t be found in the genome. The process of recombination is possible because, DNA molecules from all organisms share the same chemical structure (nucleotides are same among different species, difference is only in the nucleotide sequence).
The answer is R. The structure of singulair (montelukast), a medication used to manage asthma, the absolute absolute configuration of the chirality center is r and not s. Montelukast is aeukotriene receptor antagonist used to relieve symptoms of seasonal allergies.and used <span>for the maintenance treatment of asthma.</span>
