Answer:
I think that birds have different bill lengths because of their habitats and their diet. Also natural selection and evolution has also played a factor due to the fact that birds have not always looked the way that they do now, for example the Archaeopteryx a bird that lived around the time of the dinosaurs had a shorter and more powerful bill to grind insects and small mammals
Explanation:
The significant role of spore formation in the reproductive cycle of this bacterium would be to allow the bacteria to survive in extreme conditions. The spore formed is called an endospore which is a thick cover made of protein. These spores are mostly resistant to heat and chemicals which makes the bacteria survive in harsh conditions. Spores can only be destroyed by sterilization and it require very high pressures and very temperatures. In microbiology and medical settings, this process is usually done in a device known as the autoclave. Sterilization is a process that involves the killing of all microorganism in a system whether it is harmful or beneficial.
Answer:
Grass
Explanation:
Biotic means living. There are some obvious abiotic factors here. The only gray area is what "soil" encompasses
grass-Biotic means living, all of the other choices are not living, and would therefore be abiotic factors
This is because it is a living thing (performs photosynthesis and cellular respiration).
Biotic means living, all of the other choices are not living, and would therefore be abiotic factors
An exothermic chemical reaction is change in the chemicals that can never be undone, an exothermic solution is a combination of chemicals
