The human gut microbiome is a collection of microbes that are necessary for proper function of the digestive system and that con
Fiesta28 [93]

Answer: Gut microbiome degrade the ingested milk sugars through a biochemical pathway, producing ATP required for the energy needs of infant.

Explanation:

The human breast milk fed on by infants  contains a high concentration of indigestible oligosaccharides which include lacto-N-tetraose and lacto-N-fucopentaose.

These milk sugars are utilized by microbes in the gut of infants, yielding lactate as the final product of metabolism and releasing several molecules of ATP as useful energy for use by the infant.

Thus, the presence of these gut microbes at birth, and the feeding of infant with breast milk is vital to fulfilling their energy needs

Exercise scientists at an Olympic training center want to monitor athletes to determine at what point their muscles are function
RoseWind [281]

Answer:

The correct answer is option c, that is, lactic acid.

Explanation:

One can determine the anaerobic function of muscles by observing the levels of lactic acid buildup in muscles. The production of lactic acid in muscles takes place by the process of anaerobic respiration. At the time of rigorous training or exercise, one requires more amount of energy for a short burst of time.  

As oxygen is already used for higher purposes in the body, the levels of oxygen get reduced for performing any more activities. Thus, in order to generate more energy the process of anaerobic respiration takes place. Anaerobic respiration is the form of respiration that takes place in the absence of oxygen. In the process, one molecule of glucose gets transformed into two molecules of lactic acid, which gets accumulated in the muscles. This production of lactic acid provides a quick form of energy, which is utilized at the time of intense training and thus, one can check the anaerobic functioning of the muscles by observing the levels of lactic acid in the muscles.

How could you use a microscope to help determine whether a specimen is a living or nonliving thing
lara [203]
<span><em>Whether living or non living:</em>
<em>When you put a sample of tissue under a microscope, if u can see a cell membrane, and can identify some cell structures like nucleus, mitochondria, vacuoles etc. , it was living, if not, its a non living thing.</em></span>

<span><em>However some cells don't have a nucleus( eg. prokaryotic cells), but all cells have a cell membrane or some sort of protective covering to contain the cell's insides. </em></span>

<span><em>To check if your specimen maybe-once living, maybe-still living "something", is living, get a look at it through an electron microscope - thats the best microscope ever- and see if the mitochondria's making any ATP( adenosine triphosphate, source of energy for most organisms), if it does, its living. If not, no</em></span><em>n living. :)</em>

What protein is responsible for the initial step in unwinding the DNA helix during replication of the bacterial chromosome?
maw [93]

Answer:

Proteins play a fundamental role for life and are the most versatile and diverse biomolecules. They are essential for the growth of the organism and perform a huge amount of different functions.

The passage of DNA to proteins begins with the step of transforming genetic information into an intermediary between DNA and protein. This intermediary is called messenger RNA (mRNA). The difference between DNA and mRNA is that the second corresponds to a very small fraction of all DNA, consists of a single chain (it is no longer a “zipper” but a strand), and that Thymine (T) is replaced by the Uracil (U). This fraction corresponds to the stretch of DNA that contains the sequence necessary to ultimately synthesize the protein.
