Stems can be said to be like a street with two way traffic because it performs two sole functions; stem transfers water and minerals to the leaves in upward direction for the photosynthesis to take place by xylem. Also, it transfers the food (glucose) from the leaves to other parts of the plant in downward direction by phloem.
Answer:
The correct answer is option b. "False".
Explanation:
There is still not definitive evidence that let paleontologists conclude whether dinosaurs were endotherms, in other words, warm-blooded animals able to heat themselves without the sunlight. Actually, evidence suggest that dinosaurs' fast pace to growth did not allowed them to be neither ectotherms nor endotherms. The most accepted theory is that dinosaurs occupied a middle ground called "mesotherms".
Answer: so whats the question
sorry if i failed to make it out
and
you typed that all in!!!
Explanation:
The fossil record is important for evolution because they show that life from the past is different from life today. Scientists, such as paleontologists can determine the age of fossils by using technology provided today; known as radiometric dating, to sort them and determine relationships with organisms today. It allows us to get a whole view on the possible relations of today.
Homologous Anatomical Structures provide such a big support to the thought of evolution as well. They are structures that are similar in some organisms because they were inherited from a common ancestor. The functions may or may not have been used by the past ancestors, either. This supports evolution widely due to us seeing what we've evolved from, and what animals have evolved from. It allows us to determine ancestors as well.
Embryology is a very good one, looking at the early stages of animal development. This allows scientists learn about how different species have evolved over time. It supports evolution largely due to this. A very good branch of science, spreading the thought of evolution each and everyday.
Apologies- I don't have an answer for the other explanations.
Autotrophs because they make their own food and therefore are producers in the food chain
