The heaviest object ever directly weighed was the Revolving Service Structure (RSS) of launch pad 39B at NASA's Kennedy Space Center, Florida, USA. The structure was lifted up on 21 jacking points which, between them, measured the mass of the RSS as 2,423 tonnes (5,342,000 lbs).

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.

Help pls- <br><br> compare and contrast evaporation and boiling

DENIUS [597]

So the simple answer would be evaporation is slow and can only occur through the surface of a liquid and it cools it down, while boiling is fast and produces bubbles ( evaporation does not ) and it occurs throughout the liquid and doesn’t cool it down. A similarity between the two would be water vapor is given off
Both the processes of evaporation and boiling result in a change from liquid to vapor.

hope this is what u we’re looking for and this helps !! :)

Babies with very low or very high birth weight are less likely to survive. The graph shows the percentage of babies born at

dalvyx [7]

Answer:

Option C is correct.

The information provided clearly shows that the babies with average weights form a stable selection, the average is favoured.

Stabilizing selection is occurring because the average is favored.

Explanation:

Concluding Part of the question

A graph entitled Percentage of Babies born at Different Weights has weight in pounds on the horizontal axis, and percentage on the vertical axis. A small percentage of babies are born at the low and higher birth weights, and a greater amount are around 7 to 8 pounds.

Which statement is a valid claim that could be made using the data in the graph?

A) Directional selection is occurring because the graph favors an extreme.

B) Disruptive selection is occurring because the two extremes are favored.

C) Stabilizing selection is occurring because the average is favored.

D) Biodiversity variation is occurring because there is an increase in trait variation.

Explanation

Stabilizing selection represents a form of natural selection where the intermediate variants of a trait, that is the non-extreme trait values are the ones that ensure the survival and subsequent formation of stable population of the species with this average traits.

In this question, it is given through the data from the graph that babies with very low or very high weights are less likely to survive.

And it is logical as very low weight babies are most likely to be very weak, fragile and susceptible to being on the wrong side of natural selection and very high weight babies have all sorts of overweight issues plus the fact that they have to literally be squeezed out of the womb through a very narrow canal, really pushing their oversight bodies to its limits very early making them also susceptible to being on the wrong side of natural selection.

The average weight babies on the other hand do not experience any of the issues discussed in the last paragraph, they are usually healthy and thus have a high survival rate. So, it is evident to see that the population of babies stabilizes based on a particular non-extreme trait value (baby weight) through stabilizing selection.

Hope this Helps!!!
