Which of these statements about DNA is true.
1.All animals have DNA.
2.Proteins signal the cells to make DNA.
3.DNA is too similar to use for grouping organisms.
4.DNA is a protein
.Which characteristic is common among vertebrates?(1 point)
1.make own food
2.eat with teeth
3.supported by an exoskeleton
4.breathe with lungs or gills
Which characteristic is common to a starfish and snail?
1.both are mollusks
2.both are echinoderms
3.both are the same size
4.both are invertebrates
Which characteristic distinguishes animals from plants?
1.Plants are made of cells.
2.Animals reproduce.
3.Animals consume other organisms.
4.Plants evolve through natural selection.
1. All animals have DNA is true.
2. Breathe with lungs or gills is common among vertebrates.
4. Both starfish and snail are invertebrates.
3. Animals consume other organisms distinguishes animals from plants.
1. The statement "All animals have DNA" is true. DNA is the genetic material that contains the instructions for the development and functioning of all living organisms, including animals.
2. The statement "Proteins signal the cells to make DNA" is not true. Proteins are involved in various cellular processes, but they do not directly signal the cells to make DNA. DNA replication is a complex process that involves the actions of multiple enzymes and proteins.
3. The statement "DNA is too similar to use for grouping organisms" is not true. DNA analysis is widely used in biology to study and classify organisms. DNA can provide valuable information about the evolutionary relationships and genetic diversity among different species.
4. The statement "DNA is a protein" is not true. DNA (deoxyribonucleic acid) is a nucleic acid, not a protein. It is composed of a sequence of nucleotides and is responsible for storing and transmitting genetic information.
Among the given options, the characteristic common among vertebrates is "breathe with lungs or gills."
Neither of the options 1-4 is correct for the characteristic common to a starfish and a snail. The correct answer is: There is no common characteristic between starfish and snails.
The characteristic that distinguishes animals from plants is "Animals consume other organisms." While both plants and animals are made of cells and can reproduce, the ability of animals to actively consume and obtain nutrients from other organisms is a characteristic that sets them apart from plants. Plants, on the other hand, produce their own food through photosynthesis.
