Answer: The enzyme increases the effectiveness of reactant collisions thereby increasing the number of reactant molecules that reach activation energy.
A reaction occur if the substrates needed collide with each other. Enzyme is like a mold that can hold the substrate so that it will be easier to collide. The effect of enzyme could be seen in the activation energy needed to do the reaction because enzyme lower it very much. This will help speed up the reaction so it create product faster.
The correct answer is primary spermatocytes.
The process of spermatozoa development from germ cells is called spermatogenesis and it occurs in the seminiferous tubules of the testis. The germ cells move towards the lumen as they mature. There are 4 phases of spermatogenesis:
1. Mitosis of spermatogonia-primary spermatocytes are produced
<span>2. First meiosis - form the primary spermatocytes to the formation of secondary spermatocytes
</span> <span>3. Second meiosis-formation of the spermatids
</span> <span>4. <span>Spermiogenesis-up to the completed sperm cells.</span></span>
Stage 3 and stage 4 pressure ulcers may require debridement
Debridement definition - surgical removal of foreign matter and dead tissue from a wound
Chloroplast are found in leaves because they absorb more sunlight which is needed for photosynthesis to produce food for the plant .
