Answer:

The polarity of membrane phospholipids

Explanation:

The inner core of membranes is made of nonpolar tails of phospholipids which in turn makes the membranes impermeable for polar, large and charged substances since these substances cannot cross the non-polar inner core. The saturated hydrocarbon tails pack tightly and make membrane less permeable while cholesterol affects the membrane permeability by interacting with non-polar tails.

Higher temperatures make the membrane more fluid and more permeable while at lower temperatures, membranes are more rigid due to tight packing of hydrocarbon tails and less permeable. The polar heads of phospholipids make the inner and outer surface of the membrane. Therefore, the polarity of phospholipids does not affect the membrane permeability.

Please help me...Why is it important for a health care provider to maintain accurate patient records?
Serggg [28]

Answer:

Explanation:

An accurate written record detailing all aspects of patient monitoring is important, not only because it forms an integral part of the of the provision of care or nursing management of the patient, but because it also contributes to the circulation of information amongst the different teams involved in the patient’s treatment or care.

In a legal sense, documentation and record keeping is also there for the protection of the nurse or healthcare professional.

A well-kept record can protect the practitioner in instances where the legal defence of their actions is required. Documentation also ensures a matter of professionalisation and proof of the improvement of practices.

Can anyone tell me the ratio of the genotype and phenotype ???
iogann1982 [59]
<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2><h2>_____________________________________</h2><h2>Phenotype:</h2>

It is the physical appearance of the trait, whether the person has smooth chin or cleft chin.

<h2>Genotype:</h2>

A genotype refers to the genetic characteristics of an organism's trait, if it is heterozygous or hom.ozygous, recessive or dominant.

<h2>_____________________________________</h2><h2>Alleles:</h2>

Cleft chin C is dominant over smooth chin c

<h2>Genotypes of Parents:</h2><h3>FATHER:</h3>

Father has smooth chin thus, it is hom.ozygous recessive i.e. cc

<h3>MOTHER:</h3>

Mother has cleft chin, since cleft chin is dominant there are two possibilities of her genotype,

                           Heterozygous Dominant : Cc

                           Hom.zygous Dominant : CC

but if we cross the hom.zygous fominant mother to hom.ozygous recessive father we will get all the offsprings with the same genotype phenotype so it is not possibile, So the mother is HETEROZYGOUS DOMINANT Cc

<h2>_____________________________________</h2><h2><u>Question</u>:</h2><h2>_____________________________________</h2><h2>Genotypes of Parents:</h2>

FATHER: cc (Hom.ozygous Recessive)

MOTHER: Cc (Heterozygous Dominant)

<h2>_____________________________________</h2><h2>Punnet Square:</h2>

Picture attached!

Picture no 1: it is the cross between hom.ozygous recessive father and hom.ozygous dominant mother and all the offsprings are same both phenotypic and genotypic way so IT IS NOT POSSIBILE

Picture no 2: Its cross between hom.ozygous recessive father and heterozygous dominant mother and there are hybrid and pure recessive both type of offsprings present thus IT IS POSSIBLE!

<h2>_____________________________________</h2><h2>Genotype Ratio of the Offspring:</h2>

Hybrid : Pure Recessive

2 : 2 or 1 : 1

<h2>_____________________________________</h2><h2>Phenotype Ratio of the Offspring:</h2>

Cleft Chin : Smooth Chin

2 : 2 or 1 : 1

<h2>_____________________________________</h2><h2>Best Regards,</h2><h2>'Borz'</h2><h2 />
