There are many reasons but to name a few:

-prevents respiratory problems such as asthma, hyperreactive airway, shortness of breath, etc.

-good for digestion

-prevents snoring

-the nasal hair filters out chemicals from the air, while the mouth has no filter.

50N of force is applied to a kg box. What will the acceleration be
Cloud [144]
<h2>ANSWER:</h2>

\huge\boxed{50\frac{m}{s^-2}}

<h2>_____________________________________</h2>

DATA:

Force = 50N

Mass of the Body = 1kg

Acceleration = ?

<h2>_____________________________________</h2><h3>SOLUTION:</h3>

By the second law of newton,

                            F = ma

Rearrange the equation,

                             a = \frac{F}{m}

Substitute the variables in the equation,

                             a = \frac{50}{1}

OR,

                              a = 50 m/s^2

Binding of glucose to hexokinase causes a conformational change in the enzyme. This is an example of the __________ model of enz
irina [24]

Answer:

Binding of glucose to hexokinase causes a conformational change in the enzyme. This is an example of the<u> induce-fit </u>model of enzyme catalysis.

Explanation:

The induce- fit model is generally the most accepted theory for enzyme catalysis. This theory states that the active site of an enzyme is not always a perfect fit for a substrate. The substrate induces changes in the active site so that it can fit into the active site. This theory is contrary to the theory of lock and key model, which stated that substrates exist as a perfect match for particular active sites of an enzyme.

Higher Ultra-Processed Food Consumption Is Associated with Increased Risk of Incident Coronary Artery Disease in the Atheroscler
Eddi Din [679]

Yes, it is true that Higher Ultra-Processed Food Consumption Is Associated with Increased Risk of Incident Coronary Artery Disease in the Atherosclerosis Risk in Communities Study.

Objectives:

To test the hypothesis that higher intake of ultra-processed foods is associated with higher risk of coronary artery disease.

Methods:

A total of 13,548 adults aged 45-65 y from the Atherosclerosis Risk in Communities study were included in the analytic sample. Dietary intake data were collected through a 66-item FFQ.

Ultra-processed foods were defined using the NOVA classification, and the level of intake (servings/d) was calculated for each participant and divided into quartiles.

We used Cox proportional hazards models and restricted cubic splines to assess the association between quartiles of ultra-processed food intake and incident coronary artery disease.

Results:

There were 2006 incident coronary artery disease cases documented over a median follow-up of 27 y.

Incidence rates were higher in the highest quartile of ultra-processed food intake (70.8 per 10,000 person-y; 95% CI: 65.1, 77.1) compared with the lowest quartile (59.3 per 10,000 person-y; 95% CI: 54.1, 65.0).

Participants in the highest compared with lowest quartile of ultra-processed food intake had a 19% higher risk of coronary artery disease (HR: 1.19; 95% CI: 1.05, 1.35) after adjusting for sociodemographic factors and health behaviours. An approximately linear relation was observed between ultra-processed food intake and risk of coronary artery disease.

Conclusions:

Higher ultra-processed food intake was associated with a higher risk of coronary artery disease among middle-aged US adults. Further prospective studies are needed to confirm these findings and to investigate the mechanisms by which ultra-processed foods may affect health.

Job specialization can most likely result in _____.
Snezhnost [94]

Answer:

Employee boredom

Explanation:

When an employee specializes in a specific part of job, and it tends to be repetitive each day, it leads to Employee boredom . Therefore, there should always be novel challenges and tasks in work place which do not make an employee feel boring about same monotonous work each day in which they are already specialized.

This never intends to mean that Job specialization is a bad thing, but there should be versatility in work because the work of repetitive nature tends to create a sense of boredom in person and makes his mind less creative as he is doing something daily on which he is expert and do not needs more learning.

Hope it helps!
