Biotic Factors depend/rely on abiotic factors because living things (biotic) need nonliving things (abiotic) to survive. Biotic rely on other Biotic factors because they need the food and resources from other living things.
For example, we (biotic factors) need energy from the sun and oxygen/air ,which is abiotic factors, to live and grow. Just like plants (biotic) need the sun's energy (abiotic) to help it grow.
I hope u understand me. Sorry If u don't
They allowed scientists to study heredity and further develop it
If the respiratory membrane is composed of two layers of
stratified squamous epithelium, it will mostly contain numerous cell layers
because it is its composition of having to be a stratified squamous epithelium.
Another thing, the tissue will most likely be a shield for this type of
epithelium will serve as a protection against abrasion of which the respiratory
membrane will be protected of.
Hello!
During replication, DNA sequence is maintained in the new strands
The reason for it is the action of DNA Polymerase. This is an enzyme who has the function of "proofreading" the DNA sequence to ensure that all nucleotides are in the right order. This process is so accurate that an incorrect base is introduced every 10⁹-10¹⁰ bases.
Sensory neurons receive impulses and carry them from the sense organs to the spinal cord or brain. Interneurons connect sensory and motor neurons and interpret the impulse. Motor neurons carry impulses from the brain and spinal cord to muscles or glands. Draw and label the structure of a typical nerve cell.
