Answer:

1000 sperm per second

Explanation:

Spermatogenesis is the process through which sperms are produced, testicles constantly produce sperms in the male body but the whole process takes almost 64 days normally.

For a man of age 25 the normal range of production of sperm per second is 1000. However, at the end of the cycle of sperm production that is after 64 days, 8 billion sperms are regenerated.

What is used to break the bonds of nodules??
olga_2 [115]
<span> </span><span>Bean roots will have no nodules if there are no compatible Rhizobium bacteria in the soil. The nodule is a symbiotic relationship between the plant and the bacteria. Nitrogen fixing root nodules are pinkish in color. Green root nodules indicate actively reproducing bacteria that are not fixing nitrogen. The number of nodules depends on the amount of innoculant (Rhizobium) available in the soil. Look at the photos and make an estimate like x nodules per y linear inches of root. Hope this helps.

The edible part of the radish root functions as a food storage organ. The string parts of the radish root function as normal roots absorbing water and dissolved nutrients. Bean roots have no modifications for food storage. Radish roots don't have nodules. The radish root is a "tap root". The bean root is a "fiberous root" 

Beans don't grown faster than radishes because of the root nodules. Bean seeds are large. Radish seeds are small. The energy stored in the bean cotyledons helps the seedling get a fast start. The radish gets a slower start from less stored energy.</span>

Identify the 2 major groups of enzymes that make the redox reactions possible: Describe their role in these reactions.
adell [148]

Answer:Enzymes that makes redox reactions possible in a biochemical process includes those that help to catalyze the transfer of electrons, atoms, or functional groups.

Explanation:

Here are some class categories of these enzymes and their roles ;

• Oxidoreductases - Transfer of electrons (hydride ions or H atoms)

• Transferases - Group- transfer reactions

• Hydrolases - Hydrolysis reactions (transfer of functional groups to water)

• Lyases - Addition of groups to double bonds, or formation of double bonds by removal of groups Transfer of groups within molecules to yield isomeric forms

• Isomerases - Formation of C-C, C-S, C--0, and C-N bonds by condensation reactions coupled to ATP cleavage

The above are however classified, given code numbers, and assigned names according to the type of transfer reaction, the group donor, and the group acceptor.
