Amanda [17]3 years ago
8 0

Answer:

See the answer below

Explanation:

Aslam answered 34 correctly out of 70;

Percentage score = 34/70 x 100%

        = 48.57%

Imran answered 61 correctly out of 85;

Percentage score = 61/85 x 100%

     = 71.76%

<em>The percentage score of Imran is 71.76 while that of Aslam is 48.57, hence, </em><u><em>Imran is better than Aslam when it comes to quizzes.</em></u>

B. theory that the first organisms on Earth were heterotrophs

C. close relationship between fish and mammalian reproductive patterns

D. close relationship between humans and annelids

rusak2 [61]

Answer:

E. glucosuria (glucose in the urine)

Explanation:

Generally, glycosuria occurs in patients with kidney changes due to diseases such as Wilson's disease or cystinosis, can also be a hereditary problem, but is not expected in patients with kidney damage caused by prolonged lithium use.

Normally, the kidneys filter the blood, eliminating all substances that are not necessary for the body to function, while glucose is reabsorbed in the blood because of its importance in energy production, but people with renal glycosuria do not reabsorb glucose. , which causes it to be eliminated in the urine, occurring glucosuria.

When enzymes are elongating (building) a newly synthesized dna strand in pcr, new nucleotides are being added to the ____ of the
Tamiku [17]
The correct answer is c. 3 ' hydroxyl of deoxyribose.  
<span>
During the DNA synthesis via PCR, polymerization occurs in 5’-3’ direction. This means that enzyme DNA polymerase which synthesizes a new DNA strand is complementary to the DNA template strand (3’-<span>5’ direction). 5’ phosphate group of the free nucleotides which are added is attached to the 3'-hydroxyl group at the end of the elongating DNA strand.</span></span>

The wechsler intelligence scale for children (wisc) is a good indicator of innate "genetic" ability for:
goblinko [34]

Answer:

The wechsler intelligence scale for children (WISC) is a good indicator of innate "genetic" ability for children of six to sixteen years old.

Explanation:

Wechsler Intelligence Scale for Children (WISC) is basically a system of testing IQ of children from six to sixteen years old. This testing was created by David Wechsler, who stated that intelligence is a global quality and it should be reflected in children's verbal as well as non-verbal abilities.

This testing system is used by schools for several purposes:


• To evaluate the performance of kids during placement process.  

• It is also used to evaluate abilities of dis-abled children or  deferentially able children.

• IQ scores from WISC can be used to diagnose the problems of the children such as mental re-tardation or some specific learning dis-ability. It can also be used to determine the problems of the children who face hyperactivity or attention deficiency.


• In addition, the test can also diagnose brain related and neuro-psychological disorder.


Point to remember:

The WISC system is not useful to determine the extreme form of intelligence like IQ below 40 and above 160. Wechsler himself focused on this point many times that test is not adequate for children with IQs of below 70 or above 130. Despite of this fact, people use this test to determine the intelligence of deferentially able children who usually have IQ above 130 that is not very appropriate thing.

The pKa of an acid depends partly on its environment. Predict the effect of each of the following environmental changes on the p
Galina-37 [17]
The pKa represents the pH of the medium at which the zwitterionic amino acid assumes most stable ionic form due to structural stabilization. As the pKa is dependent upon the environmental factors of the solution around the amino acids, a change in their structure and localization can cause change in the pKa of the protein. Thus, the answers can be found as below:

Part A: Decrease (As the lysine is basic in nature, it will tend to stabilize the electrostatic interaction and weak interactions between the acidic amino acids and hydrogen bonds in the viscinity, thus lowering the pH and hence pKa of the protein)

Part B: Increase (As the carboxyl group is acidic in nature, removal of it will tend to increase the pKa since the basic amino acids will tend to accumulate more negative charge in their viscinity)

Part C: Increase (As glutamic acid is an acidic amino acid, its shift from outside to a non-polar site will prevents its ionization and hence the pKa will tend to shift from slightly acidic to slightly basic, hence increase)
