B) Crossing over is the correct answer to the question
Answer:
Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.
Answer:
Two
Explanation:
Consider the sequence ATGACATGCAATTGA.
Originally, there are 5 codons, translating to a minimum of 5 amino acids: ATG CAT GTC AAT TGA.
A base was inserted after the first G and the third T was deleted, the sequence become (assuming A is the inserted base);
ATG <em>ACA TGC</em> AAT TGA
<em>Only the second and the the third codon are changed and hence, their respective amino acid.</em>
Answer:
Positive affect" refers to one’s propensity to experience positive emotions and interact with others and with life’s challenges in a positive way. Conversely, "negative affect" involves experiencing the world in a more negative way, feeling negative emotions and more negativity in relationships and surroundings.
These two states are independent of one another, though related; someone can be high in positive and negative affect, high in just one, or low in both. Both states affect our lives in many ways, particularly when it comes to stress and how we handle it.
Answer:
False
Explanation:
The correct answer is false because Reabsorption of water and other filtered solutes like vitamins, sodium e.t.c. take place in the proximal convoluted tubules.
Reabsorption is when water and solutes in the PCT are removed and moved back into the blood and it's a process that take place through bulk transport.
The solutes and water are transported from the PCT to the interstitium and then move into peri-tubular capillaries and reabsorption in PCT is isosmotic i.e solutes have the same osmotic pressure.
