Answer: 1,2 and 3.

The following are common to transformation, transduction and conjugation.

1. Unidirectional transfer of genes.

2. Incomplete gene transfer.

3. Homologous recombination.

Explanation:

Transformation is the taking up of free DNA from the environment.

Transduction is the transfer of DNA by bacteria to a viruses.

Conjugation is the transfer of Plasmid or circular DNA through a tube between the cells. Incomplete DNA are transferred unidirectional .

During cell division, genetic material is contained in structures called
777dan777 [17]

The right answer is D-chromosomes.

Chromosomes are visible only at the time of cell divisions (mitosis or meiosis). They essentially contain the molecules of A.D.N. carriers of genetic information and proteins such as histones that maintain the structure of chromosomes.

Each species contains a number of chromosomes of its own. In most sexually reproducing species, non-sexual cells (somatic cells) possess duplicate chromosomes, one of which is derived from the male gamete and the other from the female gamete. These species, individuals or cells are called diploids. Gametes that contain only one chromosome of each pair are called haploid.

Is it possible for natural selection to create a new species? Explain your answer. *
mel-nik [20]
Yes, natural selection can create different species because over time one species will turn into subspecies and as soon as one subspecies cannot breed with the other subspecies they are no longer the same species. Natural selection creates species through adaption and survival of the fittest, so yes natural selection can create different species.

Brums [2.3K]

Answer: Lipids.

Explanation:

The large carbon -hydrogen bonds(C-H) in chains of lipids makes them ideal storage of energy.

T<u>he more C-H bonds breakage, the higher protons availability from Citric acid cycle NADH and FADH2  and hydrogen atom splitting (to protons and electrons) for  the electron transport chains (ETC</u>), and therefore the higher proton pumps for  more ATP's synthesis in the mitochondria matrix.  

In addition large number of electrons  surrounding carbon atom in fatty acids than other food molecule is added factor.  The transfer of these electrons to oxygen during oxidation of fatty acids releases large amount of energy (9 kilo calorie) into the cells,  more than other food substances
