Explanation:
In evolutionary theory, the relationship between the rough-skinned newt and the common garter snake is considered an example of co-evolution. The mutations in the snake's genes that conferred resistance to the toxin have resulted in a selective pressure that favors newts which produce more potent levels of toxin.
The most common condition is whether or not there is a source of water on the planet
It moves by the process of active transport which happens against the concentration gradient
Answer: C. When they mixed, some of the bacteria from strain X obtained plasmids from strain Y, these plasmids gave them DNA that allowed them to resist the antibiotic.
Explanation:
Conjugation is a mode of sexual reproduction used by some strains of bacteria to reproduce. In this the bacteria transfers the genetic material to another bacteria through direct contact. In this one bacteria act as a donor and another one act as a recipient.
The strain X which was affected by the antibiotic might have mixed with the strain Y, as a result of this strain X being not resistant with the antibiotic died. But when this bacterial strain got mixed with the strain Y, which is antibiotic resistant. The strain X might received the antibiotic resistant property from strain Y through sexual reproduction by the mode of conjugation. In this plasmid DNA transfer from strain Y to strain X, helped strain X to develop antibiotic resistance, and further helped strain X to survive.
Answer: D: it has a large capacity to hold heat
Explanation:
The property of water is that it has a large capacity to hold heat. It should be noted that in order to increase the temperature of water to a certain degree, it requires a lot of energy thereby water helps to regulate the temperature.
Other properties of water are that it is an excellent solvent, it is polar, it has adhesive and also cohesive properties.
