By reading it three times, it’s not the last two answers since it didn’t mention it, and it’s not the first one because that it “doesn’t harm the toad”. So your answer is the second one; “It increases its survival as it better evades predators”. If you see a link like that again, don’t click on it. Actually, take a screenshot so if it’s familiar when it gets send to you again, you will know not to click it. I saw many of that same link pop up in every math problem.
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:
Sexual reproduction in plant waste energy and pollen grains because the size of pollen grains is very small and in sexual reproduction there is less chances of reaching the pollen grains to the stigma of the flower. So that's why more pollen grains will fall on the stigma of the flower in order to fertilize the ovary. For fertilization, few pollen grains are enough if reach on the stigma.
Answer:
Three tissue layers I think
Answer:
Explanation:
A cell that can differentiate into all cell types of the adult organism is known as pluripotent. Such cells are called meristematic cells in higher plants and embryonic stem cells in animals, though some groups report the presence of adult pluripotent cells
