Ruminant herbivores gain from the microflora in their gut through digestion of cellulose and in return, the microflora gets the nutrients from the ruminants. The shark doesn't benefit from the remora but the remora gets a free ride from the shark and it feeds on the leftovers from the shark's meal. The human host loses nutrients because the tapeworm gets to eat the food provided by the host. Cats provide shelter and food for the flea but the cat becomes anemic because of blood loss from its parasites.
<span>Genetic variation in bacterial made it possible for some individuals to have resistance to the antibiotic, survive, and reproduce is a statement that explains the theory of evolution very well. Some of the bacteria that became resistant to the antibiotics, passes this down the genes for drug resistance. I hope the answer helps you.</span>
Answer:
Where is the DNA template strand?
Explanation:
Answer:Proteins have many different functions, while DNA has limited functions.
Explanation:
Chemicals that make up the living organisms consists of more protein than DNA. This is because proteins have different functions while the function of DNA are limited. Excluding water and fat, the human body is made up almost entirely of protein. Most of the structural framework of the body such as bones, muscle, organs, skin and nails are made up of protein.
Protein are responsible to do most of the work in cells by acting as enzymes, hormones and carriers. Proteins are largely required for the structure, function, and regulation of the body's tissues and organs.
Answer:
New species can appear gradually through small changes in an ancestral species.
Explanation:
The new species that appear are due to hereditary variations that occur in a population. The adaptive variations are said to confer a selective advantage to organisms possessing them. The result of variations is that well adapted individuals are able to survive and reach the reproductive age and pass over their favourable characteristics to their offspring.
