a. lack a reproductive phase

b. contains hyphae

c. has spores contained in ascus

d. has spores contained in basidia

Answer is C. Truffles has spores contained in the ascus.

Explanation:

Fungi like yeasts, molds and mushrooms are eukaryotic organisms which acts as main decomposers in the environment. Black truffles are aromatic edible fungi which belong to the ascomycota phylum. They are expensive and normally seen in the southern Europe. The main feature of the ascomycota is the ascus, a sexual spore bearing cell containing spores called ascospores. Black truffles are round shaped with black-brown skin and has small pyramidal cusps. It contains tightly interwoven hyphae (long filament like structure) and numerous asci (spore bearing cells). Each ascus contains some spores called ascopores, which is specific to fungi classified as ascomycetes. Mushrooms belong to the basidiomycota phylum. They are also composed of hyphae and reproduce sexually via the formation of specialized cells called basidia which have spores called basidiospores.

Pyruvate is a direct precursor of anapleurotic reactions which produce which intermediates of the tca cycle?
Virty [35]

The correct answer is:  oxaloacetate

Anaplerotic reactions are chemical reactions that form intermediates that can be used in the further steps of metabolic pathways. These reactions are very important, because it is crucial for the cell to regulate concentrations of TCA cycle metabolites and intermediates.

The reaction in which pyruvate is converted to oxaloacetate is catalyzed by pyruvate carboxylase and it occurs in mitochondria. Also, pyruvate can be converted to L-malate, in a similar way.

At 20°C the enzyme that catalyzes the breakdown of polysaccharides functions at 1 reaction every 20 microseconds. If this enzyme
lora16 [44]

Answer:

Seven segments

Explanation:

As given in the question -  

After every  twenty microseconds one reaction occurs i.e breakdown of polysaccharides.  

This means that after every  twenty microseconds the polysaccharides is broken down  

The total time for this hydrolysis reaction is  120 micro seconds

Thus , there will be six phases of division each after every  twenty microseconds

After 1st  twenty microseconds , total segments is equal to two

After 2nd  twenty microseconds , total segments is equal to three

After 3rd  twenty microseconds , total segments is equal to four

After 4th twenty  microseconds , total segments is equal to five

After 5th twenty  microseconds , total segments is equal to six

After 6th twenty microseconds , total segments is equal to seven
