Each of the following statements concerning hair is true except

Biology
1 answer:
Levart [38]3 years ago
5 0

Answer: A. scalp hairs grow constantly throughout life.

Explanation:

Hair is a squamous keratinized epithelium which is consist of multi-layered flat cells.  Hair are made up of protein called "keratin".

The statement "scalp hairs grow constantly throughout life" is false because at a particular age or due to several factors scalp hairs stop growing.

Scalp hair growth rate depends on three main factors including sex (female hair grows faster than male), age (hair growth slows with age), and ethnicity (Asian hair grows slower than Caucasian hair).

Scalp hair growth stops because of  follicle devitalization when the hair length become two or three feet.

Hence, the correct answer is A. "scalp hairs grow constantly throughout life".

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.

What glycolysis product is transported into the mitochondria?
docker41 [41]

Answer:

This question lacks options, options are:

A) ATP

B) NADP

C) Pryuvate

D) glucose

E) acetyl-CoA.

The correct answer is C) Pyruvate.

Explanation:

Pyruvate is a very important compound for the cell since it is a key substrate for energy production and glucose synthesis (neo-glycogenesis), that is, pyruvate is the end product of glucose breakdown in glycolysis. Before entering the mitochondria, it can be converted to lactate, through an anaerobic reaction (in the absence or under oxygen supply) of low performance in energy production, when the main pathway is interfered with. It can also be converted to the amino acid alanine. Within the mitochondria, it can be transformed, by pyruvate dehydrogenase (PDH), into acetyl-coenzyme A (acetyl-CoA), the entry point (substrate) of the Krebs cycle. In addition, by means of pyruvate carboxylase, it can be transformed into oxalacetate, which constitutes the first step in neoglycogenesis.
