Which of the following statements describes a way in which bacteria differ from animals and plants?
The BEST statement that describes how bacteria differ from animals and plants is bacteria do not have membrane-bound organelles and nuclei.
Prokaryotic cells (i.e. bacteria and Archea) have no nuclei and lack organelles.In these cells (prokaryotic cells), the genetic material consists of a single circular chromosome localized in a region of the cytoplasm called the nucleoid.On the other hand, eukaryotic cells (e.g., plant cells and animal cells) have their genetic material delimited by a membrane-bound organelle known as the cell nucleus. Moreover, eukaryotic cells also have different types of membrane-bound organelles that carry out specialized functions in the cell (e.g., mitochondria, chloroplasts, Golgi apparatus, vacuoles, etc).In conclusion, the BEST statement that describes how bacteria differ from animals and plants is bacteria do not have membrane-bound organelles and nuclei.

Explanation:
The oxygen released during photosynthesis comes from molecules of water
True or False
Answer: False
Photolysis takes place in the light dependent reaction of the photosynthesis. The reaction can be represented as: H 2 O + 2 photons --> 2 e − + 2H + + O. Here, the electrons released are accepted by the photosystem to fulfill the electron gap. The last electron acceptor is the oxygen and thus, the oxygen is liberated from the water molecule. The experiments conducted by Samuel Ruben and Martin Kamen by using radioactive isotopes helped to prove that the oxygen liberated during photosynthesis came from photolysis the water.
Explanation:
Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.Carbon dioxide is released during photosynthesis. Plants which synthesise their food themselves are called saprotrophs.

TMV Assembly Each of these statements is an experimental observation concerning the reassembly of tobacco mosaic virus (TMV) virions from TMV RNA and coat protein subunits. In each case, carefully state a reasonable conclusion that can be drawn from the experimental finding.
a. When RNA from a specific strain of TMV is mixed with coat protein from the same strain, infectious virions are formed.
b. When RNA from strain A of TMV is mixed with coat protein from strain B, the reassembled virions are infectious, giving rise to strain A virus particles in the infected tobacco cells.
c. Isolated coat protein monomers can polymerize into a virus-like helix in the absence of RNA.
d. In infected plant cells, the TMV virions that form contain only TMV RNA and never any of the various kinds of cellular RNAs present in the host cell.
e. Regardless of the ratio of RNA to coat protein in the starting mixture, the reassembled virions always contain RNA and coat protein in the ratio of three nucleotides of RNA per coat protein monomer.
Answer:
Explanation:
tobacco mossaic virus is aa RNA containing virus enclosed in aaprotein coat. in above sttaed experiment when TMV cause infection in tobacco plant is leaves get infected due to replication of virus in its cells. RNA is first converted into complementary DNA and form a double stranded nucliec acid structure. it syntheaize its protein to make new coats and to wrap the newly synthesized RNA, and make a completely infected new virus which we called virion. in any case the number of coats are equal to RNA so that to prepare new viruse. n

Membrane proteins offer structural support to the membrane but have no other function. Both plant and animal cell membranes are considered fluid mosaics.
Answer:
- In water, phospholipids spontaneously arrange into a bilayer
- Steroids in cell membranes allow the membrane to be more fluid
- Phospholipid bilayers surround all eukaryotic cells
- Both plant and animal cell membranes are considered fluid mosaics
Explanation:
All living things (i.e.. both eukaryotic and eukaryotic organisms) are composed of cells, and all cells have cell membranes. In an aqueous environment, phospholipids spontaneously form bilayers: hydrophilic heads of phospholipids face the water environment at the surface of the bilayer, while hydrophobic fatty acid chains are shielded from the water in the interior. Steroids are lipids that intercalate into the bilayer of the cell plasma membrane, reducing the fluidity of the membrane. Integral membrane proteins may have different biological roles. For example, permeases are integral membrane proteins that facilitate the diffusion of certain molecules (e.g., glucose) across the cell membrane by passive transport. Both plant and animal cell membranes are considered fluid mosaics where different types of molecules (e.g., phospholipids, cholesterol, proteins, etc) are constantly moving across the membrane.

Answer:
The definition of kinetic energy (also called energy of movement) is a form of energy that an object has which involves motion, and it's a property of a moving object and depends not only on motion but also on mass.
The definition of thermal energy (also heat energy) would be: the energy that's inside of a system that has sole control over its temp.

Suppose you are given an unknown solution and you need to test its pH. The pH meter is broken, and all you have is the indicator bromothymol blue to use. You add two drops of bromothymol blue to 10 mL of your unknown, and the solution turns a bright yellow. Which of the following is the best estimate of the pH of the unknown solution?
a. 8.5
b. 11.5
c. 1.5
d. 7.0
Answer: The best estimate of the pH of the unknown solution is 1.5. Option C.
Explanation:
A substance which shows different colours in acidic and basic media is called an indicator. Typical examples of common indicators includes:
--> Litmus: colour in acid ( red), colour in base (blue) and colour in neutral (purple).
--> Methyl orange: Colour in acid (red), colour in base (yellow) and colour in neutral (Orange).
--> Phenolphthalein: Colour in acid (colourless), colour in base (pink) and colour in neutral (colourless).
--> BROMOTHYMOL BLUE: Colour in acid ( yellow), colour in base (blue) and colour in neutral (green).
The indicators are themselves weak organic acids or bases and hence slightly dissociated in solution. The colour of the indicator at any given point depends on the relative proportion of the dissociated ions to the undissociated molecules since they have different colours.
From the question, since the pH meter is broken, and the pH of the unknown solution is to be determined,using an indicator instead. The best estimate of the pH of the unknown solution is 1.5. This is so because BROMOTHYMOL BLUE is blue when the pH is greater than 7.6, green when the pH is between 6-7.6, and yellow when the pH is less than 6. And pH value of 1.5 is less than 6, indicating the solution is very acidic.

Which location has the warmer air temperature: Tarapoto or Neuquén? Why?
view the pic below.
Answer:
Palmas is closer to the equator than Neuquén. Which location has a warmer air temperature.Neuquén, because more energy is transferred from the sun directly to the air. Neuquén, because more energy is transferred from the sun directly to the surface, and then from the surface to the air.
Answer:
The climate in Tarapoto is hot, muggy, and mostly cloudy. Over the course of the year, the temperature typically varies from 70°F to 94°F and is rarely below 67°F or above 98°F.
And that is why the neuquen has the warmer air temperature!
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
