Answer:
c. Cellular respiration is affected by the availability of reactants.
Explanation:
No doubt the cell has less availability of oxygen (reactant). When the oxygen cannot be efficiently pumped to cells for proper cellular respiration to occur the respiration shifts to anaerobic that produces lactic acid as waste and soreness occurs. If cell has a sufficient amount of oxygen the cellular is no more effected.
The corect ancer i thank it is c
Answer: Photoperiod controls many developmental responses in animals, plants and even fungi These mechanisms include the detection of the light signal in the leaves, the entrainment of circadian rhythms, and the production of a mobile signal which is transmitted throughout the plant.
The answer is a production of spores which are used for reproduction.
In fungi, the fruiting body contains spores, which are the fungi's reproduction units. Spores are released by wind, rain, or animals. Once they land on an adequate surface they grow into hyphae, and eventually form a mycelium. The mycelium can later develop into the fruiting body and, thus, the cycle is repeated.
<h2>The Cardiac cycle</h2>
Explanation:
Correct order is: 3,5,6,4,2,1,8,7
The cycle of events that happen in a single heart beat is called Cardiac cycle. Basically, it refers to repeated pattern of contraction and relaxation of the heart.The contraction of heart is called systole and the relaxation of heart is called diastole. The cardiac cycle includes systole and diastole of atria as well as systole and diastole of the ventricles. When heart rate is about 75 beats per minute, a cardiac cycle takes 0.8 seconds.
The order of events is cardiac cycle is :
- beginning of atrial systole
- completion of ventricular filling.
- beginning of ventricular systole.
- closure of AV valve.
- isovolumic contraction.
- opening of semilunar valve.
- ventricular ejection.
- ventricular relaxation.
