Another way to introduce foreign DNA into bacteria is to transform or transduce them with the DNA and then allow them to mate. Bacterial mating is called conjugation, and occurs when two bacteria exchange DNA through a tube that connects them

List 2 adaptations that helped Darwin's finches survive.?
Vaselesa [24]

Answer:

Two adaptations of Darwin's Finches that helped them to survive are:

  • Beak structure.
  • Behavioral adaptations to use tools for foraging.

Explanation:

There are fourteen species of Darwin's finches that originated from a single  species of ground dwelling seed eating finch.

These Finches occupied different niche in the Galapagos island  and were widely studied by Darwin.

These finches are one of the best Examples of Adaptive radiation.

Studies state that during severe drought in Galapagos island most vegetation dried out and a few softer seeds were left.

These few seeds were quickly fed upon by the birds and only dry , hard seeds were left.

Only birds who had large and hard beaks could feed on these hard dry seeds.

To Ensure survival the Finches developed adaptations which resulted in hard and large beaks so that they can feed on those dried hard seed.

Some groups started feeding on insects and got their beaks adapted to capture and kill insects.

Second line of adaptation included changes in behaviour and cognitive intelligence where birds started using tools for foraging.

g The Electron Transport Complex (ETC) consists of four proteins. How many of these proteins directly contribute to the proton g
vladimir2022 [97]

Answer:

Three proteins directly contribute to the proton gradient by moving protons across the membrane

Explanation:

The Electron transport chain is a group of proteins and molecules incrusted in the internal mitochondrial membrane and organized into four complexes, I, II, III, and IV. These complexes contain the electron transporters and the enzymes necessary to catalyze the electron transference from one complex to the other. Complex I contains the flavine mononucleotide -FMN- that receives electrons from the NADH. The coenzyme Q, located in the lipidic interior of the membrane, conducts electrons from complex I and II to complex III. The complex III contains cytochrome b, from where electrons go to cytochrome c, which is a peripheric membrane protein. Electrons travel from cytochrome c to cytochromes a and a3, located in the complex IV. Finally, they go back to the matrix, where they combine to H+ ions and oxygen, to form the water molecule. As electrons are transported through the chain, protons are bombed through three proteinic complexes from the matrix to the intermembrane space. These are complexes I, III and IV.
