It is true that bones <span>in your joints are covered with a smooth and slippery material called cartilage.
Cartilage is the connective tissue between bones that allows the smooth movement of joints. </span>
A heart cell taken from a rat and placed in Flask A with a nutrient-rich culture medium produced heart cells after 24 hours.
A kidney cell taken from the same rate placed in Flask B with a similar nutrient-rich culture medium produced kidney cells after 24 hours.
The best explanation is:
INFORMATION DICTATING CELL TYPE IS PASSED FROM PARENT CELL TO OFFSPRING DURING MITOSIS.
The answer would be –genesis and –gram.
Suffixes that have a Greek or Latin roots and that are used
to combine with other words or parts of words are not called suffixes, these
kind of affixes are called combining forms.
One combing form is –genesis.
As an independent medical term, this means the origin of
something in medicine. When a doctor talks about the genesis of a contagion, he
or she is speaking of the point of origin of a contagion.
-genesis used as a suffix, can indicate a particular process
or pathogen. Example is parthenogenesis.
One combining form is –gram.
As an independent medical term, gram indicated the metric
weight of an object as a unit of mass. If nurses talk about how much serving of
food, they are talking about it in grams.
-gram signifies something written down. Example is
pictogram.
Answer:
a. Genotype of male parent= BbNn
Genotype of female parent: bbnn
b: Progeny ratio= 1: 1: 1: 1
c: 1/4
Explanation:
a. Genotype of male parent= BbNn
Genotype of female parent: bbnn
b. Gamete formed by the male parent: BN: Bn: bN: bn in 1:1:1:1 ratio.
Gametes formed by female parent: All gametes with "bn" alleles.
c. The probability that the offspring will have a genotype of Bbnn=
Bb x bb= 1/2 Bb: 1/2 bb
Nn x nn= 1/2 Nn: 1/2 nn
Therefore, probability that the offspring will have a genotype of Bbnn= 1/2 Bb x 1/2 nn= 1/2.
Answer: Individuals with a high concentration of cysteine in their urine, show symptoms of cystinuria.
Explanation:
Cystinuria is an hereditary and rare disease in which stones of an amino acid called cystine form mostly in the kidney but also in the ureter and bladder. This is a dimeric amino acid which is formed by two cysteine molecules linked by a disulfide bond. L-cysteine is a non-essential sulfuric amino acid found in a wide variety of foods, some of which are proteins. <u>This condition is passed from parents to children so it is hereditary, the person must inherit the defective gene from both parents. </u>
Cystinuria is caused when there is a high concentration of cystine in the urine. Normally, most cystine dissolves, enters the kidneys and returns to the bloodstream. <u>However, people with cystinuria have the genetic defect that interferes with this process. </u>This condition is due to a defective transport of cystine in the apical membrane of the intestinal epithelium and proximal renal tubule. The result is an absence of cystine reabsorption in the renal proximal tubule producing an excess of cystine in urine and with the consequent formation of kidney stones. Cystine stones are very difficult to remove by lithotripsy unlike the rest of the stones. Therefore, a non-invasive therapy should be carried out to prevent the recurrence of stone formation. This therapy would be based on a high intake of liquids, alkalization of urine, and use of chelating agents. In order to preserve kidney function, a combination of these three therapeutic measures is necessary to reduce both the recurrence and the morbidity of the disease.
