Answer:
Ectoderm
Explanation:
Of the three primary germ layers in the very early embryo, the ectoderm is the one that gives place to the epidermis (epidermic skin cells).
The mesoderm will develop into muscle and bone, while endoderm turns into the lungs, stomach and other organs.
Answer:
C. A dead organism
Explanation:
A body is said to be in equilibrium if there is no likelihood of a change with relation to time. This also means that there is no detectable change in such a system.
However in relation to Biology a body is said to be equilibrium when it is dead. The metabolic state of the organism is usually zero and in a state of rest. There is absence of internal and external biochemical activity. Having life in carrying out cellular activities is the main determinant in the equilibrium state of an organism.
Answer: The answer is Morphological Species Concept
Explanation:
Species concept includes defining the differences between two or more species, especially similar species.
Morphological Species Concept is also known as Typical Species Concept, it includes defining these differences in species using their morphological attributes such as difference in shapes of their bodies, form, structure, colors, what they look like in the inside.
The Morphological Species Concept takes into account the Anatomical features or structures and not the genetic makeup or DNA of the species.
Answer:
Gqalpha.
Explanation:
The signalling processing occurs in the brain with the helps of different receptors, proteins and hormones. These receptors determines the taste sensation, visual and hearing sensation as well.
In case of the increase in the level of the diacylglycerol, the Gqalpha trimeric G protein bounds to the GTP. This subunit helps in the hydrolysis of phosphatidylinositol 4,5-bisphosphate (PIP2) to diacyl glycerol (DAG) and inositol trisphosphate (IP3) by activating the enzyme known as phospholipase C.
Thus, the answer is Gqalpha.
Answer:
macrophages
Explanation:
Macrophages are the specialized cells that perform phagocytosis which refers to the intake of microbes, pathogens, toxins, etc. to remove them from the body. During any injury, capillaries become more permeable under the influence of histamine and other substances. This allows the tissue fluid to move towards the site of infection. Monocytes are the phagocytes that arrive at the site of injury or infections along with neutrophils. Monocytes are transformed into actively phagocytic macrophages. Macrophages ingest the debris and pathogens and kill them by the hydrolytic enzymes present inside them.
