Answer:

Pneumotaxic centre in the pons region of the brain can moderate functions of the respiratory rhythm centre. Neural signals from this centre can reduce the duration of inspiration and thereby alter the respiratory rate. A chemosensltive area is situated adjacent to the rhythm centre to make necessary adjustments in the respiratory process. Receptors associated with aortic arch and carotid artery also can recognise changes in CO

​

 and H+ concentration and send necessary signals to the rhythm centre for remedial actions. The role of oxygen in the regulation of respiratory rhythm is quite insignificant.

So, the correct answer is 'Both Assertion and Reason are correct and Reason is the correct explanation for Assertion'.

Which of the following is a primary function of the active site of an enzyme?
Fiesta28 [93]

The primary function of the active site of an enzyme is to catalyze the reaction associated with the enzyme (Option c). It is a fundamental structure in the enzyme.

<h3>What is the active site of an enzyme?</h3>

The active site of the enzyme is It is a fundamental structure in the enzyme that has catalytic activity.

The active site of the enzyme is a site that binds to the substrate to form the enzyme-substrate complex.

The formation of this complex leads to the generation of one or more products of a given chemical reaction.

Answer:

Carbohydrates: Carbohydrates are the most abundant organic molecules in nature. stored in the body in the liver and muscles in the form of glycogen.

Proteins and Amino Acids: Proteins are the most abundant organic molecules of the living system. There are twenty amino acids (AA) which have been found to occur in all proteins and for which genetic codon exits.

Lipids are broadly classified (modified from Bloor) into simple, complex, derived and miscellaneous lipids, which are further subdivided. found in cell membranes, cholesterol, blood cells, and in the brain

One g of fecal matter was suspended in 99 ml saline solution (tube 1). After mixing gently but thoroughly, one ml from tube 1 wa
malfutka [58]

Answer: the cfu/g Gram-negative bacteria in the fecal sample is C = 3.0 × 10^3

Explanation:

We know that; Gram negative bacteria looks  pale reddish in color under a light microscope from Gram staining.

therefore

There are 30 red bacterial colonies counted.

1 mL of from tube 1 was removed and added to tube with 99 mL saline (tube 2) dilution is 1/100.

transferred volume  into the plate is 1 mL.

Now, we have to determine the cfu/g Gram-negative bacteria in the fecal sample

Formula to calculate CFU/g bacteria in fecal sample is expressed as;

C = n/(s×d )

where C is concentration (CFU/g) , n is number of colonies , s is volume transferred to plate , d is dilution factor.

so we substitute

C = 30 / ((1/100) × 1)

C = 30 / 0.01

C = 3000

C = 3.0 × 10^3

THERFERE, the cfu/g Gram-negative bacteria in the fecal sample is C = 3.0 × 10^3

Your teacher gives you an unknown protist to classify that is currently inactive. The protist appears to have long lash-like

appendages protruding from its cell surface. Which kind of locomotion can we expect from this protist? (1 point)

The appendages of this protist will move in a dragging motion that actively pulls the protist forward.

O The appendages of this protist will move in a sweeping motion like oars to actively propel the protist forward.

The appendages of this protist will move back and forth like a wagging tail to actively propel the protist

forward

O The appendages of this protist are not functional, and the protist moves passively via environmental forces.
