Isn’t it active transport????
Brodt and Zimbardo found that shy women who were bombarded with loud noise and told that it would leave them with a pounding heart were subsequently no longer so shy when interacting with a handsome male.
a) with a pounding heart; no longer so shy
<u>Explanation:</u>
Shy is an emotion expressing nervousness, being reserved and timidity when communicating or being with some people. Shyness is generally observed in the person who has low self-confidence and inferiority complex.
Brodt and Zimbardo found that when a woman is continuously allowed to face loud noise, initially it may lead to pounding heart and subsequently they get used to it and they will be no longer shy. These scientists also found that when woman is interacting with the handsome male they will never feel shy.
Answer:
38
Explanation:
In eukaryotic cells, the maximum production of ATP molecules generated per glucose molecule during cellular respiration is 38, i.e., 2 ATP molecules from glycolysis, 2 ATP molecules from the Krebs cycle, and 34 ATP molecules from the Electron Transport Chain (ETC). <em>In vivo</em> (i.e., in the cell), this number is not reached because there is an energy cost associated with the movement of pyruvate (CH3COCOO−) and adenosine diphosphate (ADP) into the mitochondrial matrix, thereby the predicted yield is approximately 30 ATP molecules per glucose molecule. In aerobic bacteria, aerobic respiration of glucose occurs in the cytoplasm (since bacteria do not contain membrane-bound organelles such as mitochondria), and thereby, in this case, it is expected that aerobic respiration using glucose yields 38 ATP per glucose molecule.
Mammalian fertilization comprises sperm migration through the female reproductive tract, biochemical and morphological changes to sperm, and sperm-egg interaction in the oviduct. Recent gene knockout approaches in mice have revealed that many factors previously considered important for fertilization are largely dispensable, or if they are essential, they have an unexpected function. These results indicate that what has been observed in in vitro fertilization (IVF) differs significantly from what occurs during “physiological” fertilization. This Review focuses on the advantages of studying fertilization using gene-manipulated animals and highlights an emerging molecular mechanism of mammalian fertilization.
