Germ layer is a primary layer of cells found in the embryo. The three primary germ layers that generate most of the cells in the developing mammalian forelimb are ectoderm, mesoderm and endoderm.
Ectoderm forms the outer component of a mammalian body such as skin, hair, etc. Endoderm forms the inner layer that comprises of the linings of digestive system, lungs and thyroid. Mesoderm is the middle layer that forms the skeletal system, heart, etc.
Neural tube is generated by the inward folding of the ectoderm. This process is called neurulation. Ectoderm also forms neural crest.
The blood glucose level is 7.45.
Answer:
The correct flow is - the body (a)<u> Venules/vein/vena cava</u> (b) <u>Right atrium</u> tricuspid valve (c) <u>Right ventricle</u> (d)<u> Pulmonary artery, </u>capillary bed of the lungs(alveoli)
Explanation:
Deoxygenated blood is moved from the tissues to the venules, veins or vena cava to the right atrium chamber and move through the tricuspid valve present in between both right chambers right atrium and right ventricle.
From the right ventricle, the deoxygenated blood is pumped into the pulmonary artery that takes the blood to the lungs more specifically to the capillary bed of lungs.
Thus, the flow is - the body (a)<u> Venules/vein/vena cava</u> (b) <u>Right atrium</u> tricuspid valve (c) <u>Right ventricle</u> (d)<u> Pulmonary artery, </u>capillary bed of the lungs(alveoli)
Answer:
d. introduce native flowering plants the adult butterflies need for nectar, their main food.
Explanation:
Organisms choose the habitat based on the availability of basic requirements such as food, nutrients, space, etc. in the region. The absence of one or more of these factors makes them choose another habitat. Butterflies feed on nectar made by plants in their flowers. To make the butterflies stay in the landscape, flowering plants adapted to local conditions should be planted. The butterflies would feed on the nectar of these plants and would stay in the landscape.
The answer is tree hope this helped :)
