E. By presence of paired homologous chromosomes in the meiotic cell.

Which best explains heating by convection? A. Air molecules touch the warm ground,heating them up.
B. Warm air rises and takes heat with it; eventually it cools and sinks.
C. Sunlight travels through space without the aid of fluids or solids.
D. Land and ocean absorb and re-emit heat from the sun.
First you have to ask yourself, what is convection? The definition of convection is "the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat." according to the dictionary. So think about it. Which answer talks about sinking and rising?
If you haven't figured it out yet, it's B.
your answer to this is : B)Warm air rises and takes heat with it; eventually it cools and sinks.
Heat Convection. Convection is heat transfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat, carrying energy with it. Convection above a hot surface occurs because hot air expands, becomes less dense, and rises.
I hope this helps you out
you have a great Afternoon
Entomophily is the transfer of pollen by an insect.
Transitions between biomes do not have to be sharp and sudden, which means that different biomes can share characteristics. True or False
The answer is; TRUE
The transition between two biomes is called an ecotone. The ecotone may have the characteristic of the two biomes in which it borders. It may have plant species from both biomes. Examples of ecotones are the transition zones between grassland and forest biomes in equatorial mountain ecosystem.

How does severe weather in Earth’s atmosphere affect Earth’s biosphere?
One way that severe weather in the Earth's atmosphere affects the biosphere is that it can determine ones existence. Some people can survive and some will die when there is a severe storm such as flooding, tornadoes, and hurricanes.
There are many various ways that the biosphere (the plants, animals and other life on our planet) affect climate. Some produce greenhouses gases and further warming of our planet by the greenhouse effect, while others diminish the number of greenhouse gases increasing cooling of our planet.
Which of the following is mis-matched? A. Receptor – Monitors the changes in a controlled condition and sends input to a controlled center.
B. Control center – Receives input from a receptor and analyzes it.
C. Effector – Analyzes receptor output to determine if a controlled condition is correctly maintained.
D. None of these statements is mis-matched.
C) Effector – Analyzes receptor output to determine if a controlled condition is correctly maintained.
Example; The temperature receptors detect the change in temperature (high temperature), they send the information to control center ( hypothalamus) to analyze the information and the control center send the command to blood vessels to dilate and active the sweat glands.
Most asteroids _______. 1. revolve around Jupiter
2. are made of frozen gas and ice
3. are found between Mars and Jupiter
4. generate their own heat through nuclear fusion
Asteroids do not revolve around Jupiter. Jupiter has its own moons and that is all that revolves around it that is easily visible.
Not all are made that way. In fact most are made out of rocks.
Three is correct. That's where they are.
Four is just absurd. If the earth can't do it, the other planets can't either.
3. Are found between Mars and Jupiter
The person who answered this first is tottaly correct!

Why is it important to use a weakened virus in a vaccine?
If you used a full active virus, that defeats the point of a vaccine. You will trigger your immune response, but since you would just be injecting the virus, it will make you sick, and your body will be less effective at fighting the pathogens.
Viruses in vaccines are weakened, so they essentially will not "fight" back. They most importantly just contains the antigen markers so the body can trigger the immune response, quickly eradicate the pathogen, and build up the memory cells to that virus.
Injecting a virus that is not weak will just be the same thing as if you got the virus, you will likely get sick.
