Answer:
Since albinism is an autosomal recessive trait, it means that both parents must possess the gene for it, for the albinism to occur.
Thus, David could be the father if both Rose and David are carriers(heterozygotes) for the albino allele.
Answer:
TP synthesis in glycolysis: substrate-level phosphorylation
Explanation:
-One of the substrates is a molecule derived from the breakdown of glucose
-An enzyme is required in order for the reaction to occur
-A bond must be broken between an organic molecule and phosphate before ATP can form.
Incorrect:
-The phosphate group added to ADP to make ATP comes from free inorganic phosphate ions.
-The enyzmes involved in ATP synthesis must be attached to a membrane to produce ATP.
Answer:
a. thoracic duct
Explanation:
Trunks drain into ducts. Therefore only ducts drain into the bloodstream. The answer can be either option a or b.
Why a? The thoracic duct allows lymph from the left side of the body and the limbs (left and right side) to drain into the bloodstream. The right lymphatic duct drains fluid from the upper regions of the body, the right side, right arm and the head.
Answer:
The correct answer is A and D
Explanation:
According to Russell's conception that lies in natural proton gradients. He states that Four billion years ago, alkaline fluids bubbled to produce mildly acidic oceans (As CO2 levels were about a thousand times higher, and it reacts with H2O to form carbonic acid, rendering the oceans mildly acidic). Acidity is just a measure of proton concentration, higher in the oceans than in vent fluids. This difference has given rise to a natural proton gradient across the vent membranes that had the same polarity (outside positive) which is similar to the electrochemical potential as modern cells have. This might be the reason that last universal common ancestors of all the three domains have evolved proton pumps.
