List 3 ways that microwaves are beneficial to society
1. It’s a super-fast way to get a (healthy) dinner on the table.
2. Despite what you’ve heard, it’s perfectly safe.
3. It can help migraine sufferers.
1. It’s a super-fast way to get a (healthy) dinner on the table.
For some reason, when most of us think of microwaves, we think of unhealthy (and not-so-tasty) frozen microwavable dinners. But they’re good for so much more than that! Aside from reheating leftovers, you can also use a microwave to make a tender baked potato in just eight to 10 minutes and steam veggies in two minutes with very little cleanup. You can even use it to heat up whole grains and healthy proteins. Not only does it get dinner on the table quickly (no oven preheating or waiting for pressure to release), but it’s especially great this time of year when it’s too hot to even think about turning on the oven. Beyond dinner, I use my microwave regularly to heat up oatmeal in just a few minutes and heat up non-dairy milk for quick lattés.
2. Despite what you’ve heard, it’s perfectly safe.
For several years, I admittedly avoided microwaves because I’d heard myths about dangerous toxins flying through my kitchen and other health claims. Now, I laugh about this.
After doing some digging, I’ve found that many studies confirm that microwaves are more efficient at retaining nutrients than other methods — especially roasting at high temperatures, something most all of us feel safe doing in the oven. Another important fact: Most of us are exposed to more radiation through our cell phones each day than we are with one or two sessions a day of simple microwave use.
Also, no studies to date have found that microwaves cause cancer or any other major disease in humans. The tests that do link microwaves to cancer and neurological issues have only been performed on rats — not humans — which can’t be equally compared and shouldn’t be.
The most important thing to remember when using a microwave is to skip the plastic containers. Old plastic containers could have BPA, and that can leach into our food when the plastic heats. Even if you have new plastic, why not just use glass?
3. It can help migraine sufferers.
I do not suffer from chronic migraines, but I know plenty of people who do — and many of them say that their microwaves are key to helping them manage their pain. See, there are these little bags that can get heated up, and they almost provide instant relief. Yes, you can heat these bags in the oven, but then you have to wait for the oven to heat up and then for the bag to heat up. With a microwave, you just nuke the bag for two minutes and you’re in business

All the cells in your body need ___________ to survive
Answer:
Oxygen or Minerals or Sugars (Oxygen is the most relevant one)
Explanation:
To survive, every cell must have a constant supply of vital substances such as sugar, minerals, and oxygen, and dispose of waste products, all carried back and forth by the blood cells. Without these substances, cells would die in a very short period of time.
At the end of a sunny day, Cindy turns on an electric fan to cool off her room. When she turns off the fan a little later, she notices that the area around the motor is warmer than it was when she turned on the fan. What is the most likely explanation for this?
1.Electrical energy was transformed into heat and energy of motion.
2.Solar energy was transformed into heat and energy of motion.
3.Solar energy was transformed into electrical energy and heat.
4.Electrical energy was transformed into sound and light.
Answer:
One
Explanation:
Because it never says that the fan used solar energy and 4 wouldn't make it heat up.
Which of the following statements best explains the general process of cellular respiration?
A: Living organisms use energy from the sun and water to create food in the form of sugar.
B: Living organisms take in oxygen and water to create food in the form of sugars and energy.
C: Living organisms breakdown sugar from food to combine with oxygen making usable energy
D: Living organisms take in oxygen and release carbon dioxide through the cells thereby providing energy.
Answer:
C. Living organisms breakdown sugar from food to combine with oxygen making usable energy.
Explanation:
Cellular respiration is about making food into energy. Since C is the only one with that aspect C can be the only answer.
The statement which best explains the general process of cellular respiration is: C: Living organisms breakdown sugar from food to combine with oxygen making usable energy.
Cellular respiration can be defined as a series of metabolic reactions which typically occur in living cells, so as to produce energy in the form of adenosine triphosphate (ATP).
Generally, high energy intermediates that can then be oxidized to make adenosine triphosphate (ATP) are created during cellular respiration.
Basically, the general process involved in cellular respiration can be represented by a single equation while using the following substances;
Glucose (Sugar).Oxygen.Carbon dioxide.Water.Adenosine triphosphate (ATP).[tex]Glucose + Oxygen ---> Carbon \;dioxide + Water + ATP[/tex]
In conclusion, all living organisms breakdown sugar or glucose from their food to combine with oxygen, so as to make usable energy during cellular respiration.

How are functional MRI machines being used to determine the function of different parts of the brain?
Answer:
Magnetic resonance imaging (MRI) is a technology that produces 3D images in order to assess brain activity, which is used in the diagnosis, monitoring and treatment of diseases
Explanation:
Magnetic Resonance Imaging (MRI) is a non-invasive method that generates three-dimensional (3D) images which are used for diagnostics and disease monitoring. MRI is useful to distinguish between white and grey matter in the brain, and thereby this technique can be used for the diagnosis of tumors and aneurysms which are caused by weakness in the arterial walls. Moreover, MRI is also useful to analyze the relationship between regions of the brain and cognitive processes by monitoring the neurological-psychophysiological status of an individual.

Use the codon table posted below (or the circular one on the first page) to determine which amino acids are assembled to make the insulin protein in both the cow and the human. Human DNA DNA CCA TAG CAC GTT ACA ACG TGA AGG AAA RNA GGU GLY Amino acid Cow DNA DNA CCA TAG CAT GTT ACA ACG CGA AGG GAC RNA Amino acid
Answer:
Please find the complete table attached as an image
Explanation:
This task is describing the processes of transcription and translation, which are the two processes involved in gene expression. The DNA of a human and cow is given in the table of the attached image and we're asked to transcribe into a complementary RNA, and subsequently translate into an amino acid using the CODON table (genetic code).
- Transcription is the process whereby DNA is used as a template for the synthesis of RNA based on complementary base pairing i.e. A-U, G-C, T-A etc.
- Translation is the process whereby RNA transcript is used to synthesize an amino acid sequence. The mRNA is read in a group of three nucleotides called CODON, where each of this codon specifies an amino acid.
The table has been completed and attached below. Note that in the amino acids row;
GLY means Glycine
ILE means Isoleucine
VAL means Valine
GLN means Glutamine
CYS means Cysteine
THR means Threonine
SER means Serine
PHE means Phenylalanine
ALA means Alanine
LEU means Leucine
