Answer AND Explanation:
Embryos of different vertebrate groups are morphologically similar during the early stages of development. Such similarity suggests a common ancestry. The closer the resemblance between the early stages of different organisms, the closer their evolutionary relationship.
Answer: If a mutation occurred in Silencer of Death Domain (SODD) that prohibited its interaction with the DD of TNF receptor, the TNF receptor would evoke its response by binding to a transmembrane receptor, TNFR1.
Explanation: Binding to TNFR1 inhibits the recruitment of cytoplasmic signaling proteins to TNFR1 to prevent recruitment of a number of protein (TRADD) or prevent spontaneous aggregation of the cytoplasmic death domains of TNFR1 molecules.
SODD mechanism is useful in preventing unwarranted TNFR1 activation in the process of apoptosis.
Answer:
option B) The oxygen end of the molecule has a partial negative charge and the hydrogen end has a partial positive charge.
Justification:
The electronegativity of an element accounts for its relative ability to attract electrons.
Being oxygen more electronegative than hdyrogen (the electronegativity of oxygen is 3.44 while the electronegativity of the hydrogen is 2.20), the electron density will be displaced toward the oxygen, letting it with a partial negative charge and the hydrogen with a partial positive charge.
Finally, since the charge is not symmetrical distributed around a center of the molecule, the molecule ends being polar.
