Phagocytosis is defined as a process of ingestion of bacteria or other infectious agent by phogocytes.
In human beings, the major and professional phagocytes are White Blood cells. These cells are specialized in attacking infectious agents that enters the body and kill them by engulfing them.
In protozoan, the phagocytosis starts with the ingestion step, in which an infection agent is taken up by protozoans and form a special vacuole like structure which secretes lysosomes enzymes that attack the agent and kill it and then removed from body by egestion.
Hence, there is not any significant difference between the process of phagocytosis in humans and protozoan; however the steps included vary in both.
Answer: Option A) sensory somatic nervous system-controls skeletal muscles
Explanation:
The somatic nervous system (SNS) is controlled by the brain, and direct conscious or voluntary actions by stimulating the skeletal muscles.
For instance: On seeing an oncoming vehicle, a cyclist will swerve to a safe path. This is a voluntary action, where the skeletal muscles are stimulated by the somatic nervous system to avoid hitting the oncoming vehicle.
Answer:
Cross a heterozygous male for tallness with a homozygous recessive female for tallness. Then give the genotype and phenotype ratios. Dihybrid crosses involve tracking two traits simultaneously. For example, we can predict the outcome for offspring as the traits for both height and color are concerned.
Explanation:
