Answer:
lose more heat to the environment in cold environments
Explanation:
This is because as an animal have large surface area, it is exposed largely and prone to loss of heat. The larger the size of an animal, the larger the surface area and volume. It's surface area expose the tendency for the animal to sweat alot , through sweating heat is loss to the environment. In cold environment, the animal try to maintain internal homeostasis and through this heat is generated and loss to the environment.
Answer:
While many microbes are harmless to humans, others can cause serious problems. They can spoil food, introduce toxins, cause disease and lead to a host of other problems. The importance of microbiological testing is to quickly identify these contaminants and treat them before they do irreversible damage.
Explanation:
Aerobic bacteria are bacteria that can grow and live when oxygen is present.
Nucleus is the answer
Hope this helps :D
Answer:
The RIGHT ANSWER IS- Classification of the organism and characteristics of the spines.
Explanation:
In this senerio, we will consider the characteristics of the spines followed by the classification of the given animals as porcupine, sea urchins and hedgehogs are of varying phylum.
The two common terminology mostly used in the science of evolution are homology and homoplasy. These two terms varies in their scientific connotations.
Homology is the term used to express biologicals structures or characteristics that are similar and observed in two or more varying species. The noted characteristics originates from the orgsnism common ancestor.
An illustration to describe homology is the forelimbs of frogs, birds, rabbits, and lizards. The forelimbs of this species shows difference in appearance in each species and it shows they possess the same set of bones.
In Homoplasy, the biological structure or characteristic in two or more varying species is from different ancestor.
Homoplasy also shows how it evolved independently due to natural selection in same environments.
Homology is an aftermath of divergent evolution while Homoplasy is a result of convergent evolution.
