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.

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

The correct answer is - priming.
Explanation:
Priming is a phenomenon that explains the behavior of an individual when an individual experiences a certain stimulus that influences response to a subsequent stimulus, unknowingly of the connection. This effect is known as the priming effect.
In this case, watching a cartoon of a rabbit acts as the stimulus that influences the response of identifying the image of duck as a rabbit. He is experienced priming effect.
Could you explain the roles and relationships among producers, consumers, and decomposers, and identify the distinguished characteristics of several common relationships among organisms in an ecosystem near you?
Answer:
A consumer may also eat other consumers as food. When producers and consumers die, the Decomposer will come along to decompose (break down) the bodies of the dead producers and consumers into smaller chemicals - in short treating them as a food source
Explanation:
Your welcome have a good day :)
The producers, consumers, and decomposers are related to each other in an ecosystem in a specific way.
What is an Ecosystem?The interaction between the organisms of different species plays their role in a systematic way as decided by natural selection, which is known as the Ecosystem.
Producers use light energy and inorganic matter to produce food. They are always present first in the ecosystem. Consumers take energy from plants known as herbivores, and also from herbivores known as Carnivores. Decomposers convert dead organic matter into inorganic matter. This inorganic matter helps producers perform metabolic activities. And finally, this cycle goes on.
Therefore, the producers, consumers, and decomposers are related to each other in an ecosystem in a specific way.

Which photon has the greatest amount of energy?
Answer:
Gamma rays, a form of nuclear and cosmic EM radiation, can have the highest frequencies and, hence, the highest photon energies in the EM spectrum.
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.
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!
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.

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
