The correct answer is that a bacteriophage lambda chromosome containing the human collagen gene, because Recombinant DNA is the name given to DNA molecules that have part of DNA derived from two or more sources, usually these sources are different species. Recombinant DNA technology is also known as molecular cloning or even gene cloning.

B. A bacteriophage lambda chromosome containing the human collagen gene

<h3>How is recombinant DNA produced?</h3>

Obtaining recombinant DNA is based on the molecular cloning technique. The process can be summarized as follows:

The first step is to isolate a DNA fragment, which contains the gene of interest. Remember that each gene makes a protein.
The gene of interest, now isolated, is placed in a medium with a fragment of circular bacterial DNA, the plasmid and the restriction enzymes.
The bacterial plasmid has the ability to insert a fragment of DNA external to its own genome.

DNA is the structure responsible for the transmission of all genetic characteristics — such as eye, skin and hair color, physiognomy, among others — in the process of reproduction of living beings. Thus, the main function of DNA is to transport information contained in its sequences, called genes.

Sauron [17]

Answer:

The correct answer is

1. A rabbit living in a desert has long ears to disperse heat- abiotic factor.

2. A moth immediately dives to the ground when it hears a bat- biotic factor.

3. A lizard stays warm by sunning itself on a rock- abiotic factor.

4. A cactus has spines instead of leaves to help conserve water- abiotic factors.

5. A petunia is bright red to attract hummingbirds- biotic factor.

6. A stick-bug blends in with trees to hide from predators- biotic factor.

Explanation:-

The environment includes both abiotic and biotic factors which can affect the ecosystem. Living elements like plants and animals which affect ecosystem are known as biotic factors while the non-living elements which include air, water, temperature are called abiotic factors.

In the given question the options affected by the biotic factors due to bat, due to hummingbirds and due to predators.

Options affected by the abiotic factors due to heat and due to water.
