Question Completion with Options:
a. increasing the size of your cohorts.
b. increasing the diversity of your cohorts.
c. increasing the size of your affected cohort.
d. increasing the diversity of your affected cohort.
Answer:
All of the following modifications to the study are likely to allow identification of new variants associated with the disease, EXCEPT
a. increasing the size of your cohorts.
Explanation:
Option A is chosen because increasing the size of the cohorts will be equally divided between the affected and unaffected cohorts since the study discovered that these two classes are roughly the same size. Therefore, new variants of the disease may not likely be identified and isolated unless the other modification options are followed instead of Option A.
Enzymes increase the rate of reaction
Answer:
ionic
Explanation:
Ionic bond:
It is the bond which is formed by the transfer of electron from one atom to the atom of another element.
Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.
For example:
Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion.
There are one valance electron in sodium so it needed to lose one valance electrons to complete the octet while chlorine needed one electron to complete the octet. Thus electrons lost by sodium atom is gained by atom of chlorine and form ionic compound.
2Na + Cl₂ → 2NaCl
Answer:
the golgi body packages proteins and other vesicles and send them around the cell
Answer : Option C) vestigial structures.
Explanation : In the example of whales which is displaying the remnants of the pelvis and femur bones it seems to be the example of vestigial structures.
As vestigial structures are those anatomical feature which no longer seems to have a purpose in the current form of an organism of the given species.
