Answer:
C. II and IV only
Explanation:
X linked recessive inheritance follows the criss-cross pattern in which affected mothers always have affected sons as sons get their X chromosome from mothers only. Condition "II" can not be true for X linked inheritance as hemophiliac mothers (XhXh) should have hemophiliac sons (XhY) only.
Daughters get one copy of their X chromosome from the father and the other from mother. To have affected daughters, mother should be carrier or hemophiliac and the father should be hemophiliac (XhY). This would make it possible for both the parent to transmit one copy of X chromosome with the gene to daughters (XhXh).
Answer:
You can use either your answer or the sample answer you gave. You are so nice by the way!
Explanation:
THE FOLLOWING ARE TWO ANSWERS YOU CAN CHOOSE FROM
ANSWER 1:
The red crystals are compounds. This is because when the sample is heated, a GAS (element) is released and BLUE POWDER (element) is left. Two elements make up these red crystals. A compound can also be shown through color change - the RED crystals, when heated, turn into BLUE powder. Elements cannot be broken down into substances using physical force, like heating. So yes, this is a compound.

EITHER ONE YOU CHOOSE WILL BE CORRECT, JUST SAYING!
<span>For the first step, you must isolate the cells from the media. The cells contain the DNA so you keep the cells and pellet.
The next step would be a cell lysis which causes the cells to open and the DNA to come out. At this point you would keep the supernatant, as the pellet is the cell membrane and other parts of the cell.
The chelex is to bind to transition metal ions. This would cause and DNases in the cell to become inactive because the metal ion is their cofactor. The pellet in this case would contain the chelex and the DNA would still be in the supernatant.</span>
Answer:
e) Political governance.
b) Health.
d) Personal activities, including work.
c) Education.
f) Social recreation issues.
g) Environmental conditions (current and future conditions).
a) Material life
h) Financial safety and security.
Explanation:
The quality of life is an index that is calculated by using different estimators that covers diverse aspects of human life such as, among others health, safety, happiness, security, transportation, etc. The INEGI (National Institute of Statistics and Geography, Mexico) calculates the quality of life by using the estimators above described (and others). In my opinion, the most important one of this list is political governance, because it is an underlying characteristic that has a direct effect on the further estimators, thereby affecting their performance in a short/medium-term period.
C=they are better adapted to areas with days that are 14 to 16 hours long.
