The correct answer is "mucociliary escalator intestines".
The mucociliary escalator is a mechanism that belongs to the bronchi, not the intestines. The mucociliary escalator is a mechanism of self-clearing where cilium, cilia and mucus work together to expel any material that's solid, or not too fluid or gaseous, including pathogens. From the main bronchi to the alveoli there is a moist lining produced by the specific present epithelium. This epithelium presents cilia. The cilia are embedded in mucus. The mucus is what helps in trapping any material that's solid, or not too fluid or gaseous, including pathogens. After these are trapped so that they don't progress to the alveoli, the cilia move in such a way that push the particles again to the exterior of the bronchi, like an escalator.
Point D is the point that most likely does not have any plants growing in it.
Phagocytosis of microbes by macrophages is enhanced by both the binding of antibodies to the surface of microbes & antibody-mediated opsonization of microbes
What is the function of phagocytosis?
Phagocytosis is the cellular process through which particles bigger than 0.5 m in diameter, such as bacteria, foreign substances, and apoptotic cells, are ingested and eliminated.
- Phagocytosis is found in many different types of cells and is hence an important step for tissue homeostasis.
- However, only specialized cells known as professional phagocytes are capable of high-efficiency phagocytosis.
- Among these specialized cells are macrophages, neutrophils, monocytes, dendritic cells, and osteoclasts.
Phagocytosis occurs in four stages:
I identification of the particle to be swallowed,
ii) activation of the internalization process,
iii) development of a specialized vacuole known as a phagosome,
iv) maturation of the phagosome to turn it into a phagolysosome.
Hence, the correct option is A

Answer:
Heterozygous roller/heterozygous curved, heterozygous roller/homozygous straight, homozygous non-roller/heterozygous curved, homozygous non-roller/homozygous straight
Explanation:
Answer:
b) 50kg
Explanation:
You simply use F=ma equation, newtons second law
We are given: F=500N a=10m/s^2 m=?
1) lets change F=ma to help us find the m, we divide both sides with the a so we get 
2) plug in the F and the a,
, where 
3) plug it in ur calculator and you should get 50kg
hope this helped :)
