Hello, so let's answer now the question.
00:03
So let's start with number one.
00:07
So we are asked which of the following pairs are incorrectly matched, based on the or the vertebral tissue with the germ layer.
00:18
So option a states that the heart is from the mesoderm, it is correct.
00:23
Option b states that the bone is from the mesoderm, it is also correct.
00:28
Option c states that the pitilial lining of the mouth is from the ectoderm it is also correct and we have here option d which says that neuron is from ecoterm which is correct so our answer here is we have option e option e is incorrect okay because the gut motility muscles is not from the endo derm so the smooth smooth muscles in the gut, okay, which are present in the wall of the, the smooth muscles, which are present in the wall of the gut, is not from the endoderm, but from the mesoderm.
01:17
Okay, so it should be mesoderm, not endoderm.
01:20
So this statement is incorrect.
01:22
Okay, so let's proceed to question number two about microvili.
01:28
So which of the following statement? statements here is true about the microvili so let's go directly to the answer our answer here is we have microvili provide an increased surface area you provide an increased surface area for the exchange of materials okay exchange of materials or basically provide an increased area for the increased absorption of materials into the bloodstream in the smooth or in the small intestine.
02:34
Okay.
02:34
So microvili are microscopic cellular membrane protrusions that increase the surface area for diffusion and absorption and minimize any increase in volume.
02:49
You.
02:50
Okay...
