Answer:
"Macrophages" cells are commonly dispersed (mixed in) with simple columnar epithelial cells. They are responsible for secreting mucus.
Explanation:
The parasympathetic nervous system <span>conserves energy as it slows down heart rate, increases intestinal and glandular activity, and relaxes the sphincter muscles of the gastrointestinal tract. It gets the nickname "rest and digest" for doing exactly so. Typically most active when sleeping, however is also the explanation for post-prandial fatigue, or being tired after eating (especially a large meal).</span>
The smaller a population, the greater the potential effect of genetic drift on gene frequencies.
Genetic drift is an evolutionary term which refers to the random changes in a population's allele frequencies. These changes happen by chance due to the random selection of alleles from the genetic pool in each generation. Genetic drift can lead to either loss of some alleles or the fixation of others (100% frequency). The effect of genetic drift is stronger in smaller populations. This is because, the larger the population, the larger the sample size and the slower the result of genetic drift.
Answer:
Plants and animals are living things. They feed, respire, excrete, grow, move, reproduce and are sensitive to their environment. Animals and plants need food for energy but they feed in different ways.
Tissues form organ and organ forms organ systems,then it’s a complete organism
