Ierofanga [76]

Answer:

LysThrHis, LysHisThr, HisLysThr, HisThrLys, ThrLysHis, ThrHisLys

Explanation:

You easily combine the options for the tripeptide if you made a chart

Also you can calculate the posibilities with the factorial function in the calculatio (x!): 3*2*1 (you can multiplicate the number of amoniacids by the followed numbers until 1) = 6

Answer:

A statement can contain one argument, more than one argument or no argument.

Argument are intended to determine the degree of truth hence enabling a conclusion to be made. It contains one or more premises and only one conclusion.

A premise is the statement in the argument that provides reasons to support a conclusion.

In the first statement, there is no argument. This is because there is neither a premise nor a conclusion

The second statement has a conclusion(the last sentence) and two premises(first two sentences) therefore it is an argument.

You have been growing some animal cells in a test tube. The cells grow for several days, then do not appear to grow as well. You

Answer:

D. There is no enough oxygen in the culture fluid

Explanation:

The cells in the test tube need to carryout one of the important metabolic processes of living organisms - respiration. The process involves the breakdown of glucose to generate energy for other metabolic processes in the cell.

Respiration can be carried out in the presence of oxygen (aerobic) or in the absence of oxygen (anaerobic). Human cells are primarily aerobic but can carryout respiration anaerobically in the presence of inadequate oxygen.

For aerobic respiration, glucose is broken down in the presence of oxygen to produce carbon-dioxide, water and energy in the form of ATP:

$C_6H_1_2O_6 + 6O_2 --> 6CO_2 + 6H_2O + ATP$

<em>In the absence of oxygen, the glucose becomes converted to lactic acid and a smaller amount of ATP is produced as compared to aerobic respiration.</em>

<em>Hence, lactic acid gradually builds up in the absence of oxygen due to anaerobic respiration.</em>

The correct option is D.
