Answer:
The immune system response against pathogens in order to protect our cells from the damage and prevent diseases.
There are different cells in the blood including macrophages, mast cells, and natural killer cells etcetra which recognises the specific pathogen-associated molecular patterns (PAMPs) on the pathogen’s surface. PAMPs can be classified as polypeptide, carbohydrate, and nucleic acid which are expressed by bacteria, parasites, and viruses. Immune system detects "self" from the "foreign" antigen and destroy the pathogen without damaging the host cell.
Hence, immune cells detect foreign pathogens through specific pathogen-associated molecular patterns (PAMPs) on the pathogen’s surface.
Cell division is called reproduction. a parent cell divides into 2 daughter cell. When the 2 daughter cells grow, they both divide and divide into 4 daughter cells.. that's how the process goes on and on. cell's reproduction helps us grow
Answer:
Nothing will happen.
Explanation:
Nothing will happen to the octopus population if the number of snails decreased or extinct in the area because there are many other organisms on which octopus can feed. Octopuses feed on crabs, small fishes, clams, snails, and on other octopuses so if other food sources are available to Octopus so there is no effect on the Octopus population but if there is no other food source then the Octopus population will definitely decreases due to lack of food.
I would say that the answer is A. Answers B and C are definitely wrong because DNA in eukaryotic cells are in the nucleus while two identical daughter cells are created from asexual reproduction. Answer D is wrong because you can compare two different organisms like a human and a dog. Since both are eukaryotic they will have eukaryotic cell structures with their organelles. I believe that A would be correct, if you remember the the level of organizations, then you know that cells are simple, as cells become tissues, they become a little complex, as tissues become organs, they get a little complex, finally when organ systems are formed, they are highly complex from the organs, tissues and cells. Hope that answered your question.
The prey are the food source. When the prey numbers are plentiful, there comes a period of time when the predator begins producing offspring to capitalize on the abundant food source. Offspring cant survive unless there is plenty of available food.
