A common cold virus, primarily rhinovirus, infects the upper respiratory tract of larger organisms like humans, leading to symptoms such as a runny nose, sore throat, coughing, and sneezing. The virus attaches to and enters the epithelial cells of the respiratory system, hijacking the host's cellular machinery to replicate itself. This infection triggers an immune response, causing inflammation and the typical symptoms associated with a cold. While usually mild and self-limiting, it can lead to complications in individuals with weakened immune systems or pre-existing respiratory conditions.
The weight of a microorganism can vary greatly depending on the species and size of the organism. For example, a single bacterium can weigh as little as a few trillionths of a gram, while a larger microorganism like a protozoan can weigh a few micrograms.
all organisms are made of cell, and a cell contains a nucleus that controls life activities, cell reproduction and the genes.
because they are larger and slower.
Generally, larger organisms are higher up in the food chain because they are apex predators that predate on smaller organisms. As you move up the food chain, energy is transferred and stored, so larger organisms can sustain themselves by consuming a larger quantity of smaller organisms. Larger organisms also usually have fewer natural predators to keep their populations in check.
the microorganism will stick to a cell and steal nutrients from the cell, grow larger and then to the same thing over and over to the other cells too, causing the plant to die.
The smallest classification groups, like species, have organisms with more similarities because they share a more recent common ancestor. As you move up the classification hierarchy to larger groups like phyla or kingdoms, the organisms are more distantly related and have accumulated more differences over evolutionary time.
Larger organisms are required to consume and give off lots energy to survive. But, smaller organisms do not consume and release as much energy than larger ones. This energy, when given off, is represented by heat. Therefore, larger organisms produce more heat than smaller organisms, and this extra heat is required in cold climates.
Size can indirectly affect reaction time, as larger organisms may have longer nerve pathways to transmit signals, resulting in slightly slower reactions. However, factors such as training and neurological efficiency play a larger role in determining reaction time.
Cells are the basic units of life and the building blocks of larger living organisms. They are not considered organisms themselves, but rather the fundamental components that make up all living things.
n a single-celled organism , the cell gets larger and divides, making other organisms.
Yes, the size of an organism can affect its breathing. Smaller organisms typically have a higher surface area-to-volume ratio, which means they have a larger surface area relative to their volume. This can impact how efficiently they exchange gases with their environment, affecting their breathing.
Shared derived characters are traits that are shared by a group of organisms and are unique to that group, indicating a common ancestor. Shared ancestral characters are traits that are shared by a group of organisms but are not unique to that group, as they are inherited from a common ancestor of a larger group.
