Answer: a line connecting her mother and father, a colored circle representing Jenna, and two empty circles representing her sisters

Explanation: Jenna's red hair can be determined by incomplete dominance.

Incomplete dominance is a condition where neither of the alleles responsible for a trait is dominant.

In incomplete dominance, one allele for a specific trait is not completely expressed over its paired allele. So, if an organism is heterozygous for a trait, it shows a third phenotype.

Which of the following is NOT a density-dependent factor affecting population growth?
sveta [45]

B

<u>Temperature</u> is NOT a density-dependent factor affecting population growth

Explanation:

Density-dependent factors mean variables that are affected by the density of the population. The opposite of density-depend is density-independent factors. These are those variables that affect the density of the population but are not affected by the density of the population.

In this case, temperatures are not affected by the density of the population. However, temperatures affect the density of the population. Most individuals can only survive within an optimal temperature range.

The rest of the choices are density-dependent variables

frozen elephant trunk for aortic arch reconstruction is associated with reduced mortality as compared to conventional techniques
wariber [46]

To compare the perioperative results of frozen elephant trunk (FET) vs. traditional elephant trunk (ET) procedures for aortic arch repair. 390 individuals had aortic repair with elephant trunk reconstruction between 2002 and 2018 at 9 facilities: Aortic dissection affected 37% of patients who received a FET (mean age: 65+/-13 years, 30% female), while 43% of patients who received an ET (mean age: 63+/-13 years, 37% female) experienced aortic dissection. In-hospital mortality, stroke, and spinal cord injury were among the outcomes of interest (SCI).

<h3>What is Aortic arch ?</h3>

The top portion of the principal artery sending blood away from the heart is known as the aortic arch. A combination of symptoms and signs known as aortic arch syndrome are linked to anatomical issues in the arteries that branch off the aortic arch. The valves, chambers, and accompanying vessels that make up the heart's interior.

<h3>What is conventional techniques ?</h3>

Conventional methods assess the long-term heat stability of polymer products at temperatures below their melting points, for instance, through accelerated aging in "circulating air ovens" until degradation effects like discolouration and embrittlement become apparent.
