How are food chains and food webs similar?
kolezko [41]

Answer:

Both the food chain and food web represent flow of food and energy through various organisms (including plants) and point from the producers to the consumers. Both the food web and food chain include a number of organisms including both producers and consumers (as well as decomposers).

In their simplest form, food webs are made of food chains. Food chains show a direct transfer of energy between organisms. A chain might involve a mouse eating some seeds on the forest floor.

for example A food web consists of many food chains. A food chain only follows just one path as animals find food. eg: A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. A food web shows the many different paths plants and animals are connected.

Diploid (2n) number of 38, how many chromosomes would be present in an epithelial cell
sergiy2304 [10]
The epithelial cell will have 38 chromosomes
A 2n or 2(19) = 38 chromosomes. This is because n is called haploid number of chromosomes; the number of chromosomes present in the gametes. Epithelial cells like other body cells divides through the process of mitosis; therefore; the parent cells yields daughter cells with the same number of chromosomes (diploid). The other haploid (n) number is present in the gametes which divides by the process of meiosis.
