Why is solar energy not distributed evenly over earth? Give at least THREE factors/reasons why.

Biology
1 answer:
Arisa [49]2 years ago
7 0

Answer:

  • The earth is round, meaning the part of it that is closer to the sun, will get more solar energy than the other parts which will get less. (Don't believe me? Just try placing a circle on a flat line, and see if you can get it to evenly touch.)
  • The earth is constantly rotating on it's axis, and since its axis is slightly tilted, the two poles will get different amounts of solar energy at different times. While one pole will be closer the other will be farther away, until the earth rotates of course.
  • The earth doesn't revolve around the Sun evenly, meaning instead of a perfectly even circle with equal space around the sun, it's more of an elliptical shape, or basically an oval. So this would mean the earth would be slightly further away from the sun as it completes its orbit.

I'm not an expert, nor am I absolutely sure if this is right, but I hope my answer helps.

P.S. Sorry if it's wrong

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.

A gene mutation is a change in the sequence of nucleotides that occurs during cell replication (mitosis and meiosis)within a sin
Shalnov [3]

True

Changes in the transcription of mRNA or the translation of a polypeptide are not considered to be mutations because they are not permanent changes to the cell.

Explanation:

The half-life of mRNA and proteins is short. mRNA has an average of 10 hours of life span while proteins have an average of  several days. Therefore mutation in these biomolecules will only persist as long as this mutated mRNA of protein exists. After its life-span, the molecule is degraded and replaced by a non-mutated mRNA or proteins. This is because the piece of DNA that codes for the mRNA and subsequent protein is not mutated. A mutation on DNA is the permanent kind of mutations because DNA is a highly stable molecule that stores information about the cell.
