3. List two behavioral adaptations that Darwin observed<br><br> PLZ HELP FAST
antoniya [11.8K]
Observations

The first observation is overproduction. This means all species produce more offspring than will survive to become adults. Think of all the thousands of fish eggs produced each year. This means populations of species should be getting larger all the time, but they aren't, because there are mechanisms in place to curb population explosions, such as competition for food, predation, and disease. From this, Darwin was able to make a deduction: there is a struggle for existence. Many of those fish eggs are food for predators, who would not survive without them.

Darwin's second observation was variation. This means members of the same species show variation in characteristics. For example, zebras show variation in pattern and color of their stripes. Goldfish have gold scales, orange scales, or brown scales, or a mixture of all three.

Variation applies to all traits, even those essential for the survival of the individual organism. An eagle depends on excellent eyesight to locate prey, but it can still be born shortsighted. This means that variations are random and are not specific to any favorable adaptation.

The next observation, selection , means organisms that survive are more likely to reproduce and pass on favorable adaptations to their offspring than those with unfavorable adaptations. For example, height is an inheritable characteristic, and for the giraffe, having long necks (which added to their height) was reproductively advantageous. The taller giraffes were able to reach leaves in tall trees, which kept them alive longer, and able to reproduce, making them more reproductively fit than shorter giraffes who couldn't reach those leaves and died without reproducing.

The last observation Darwin made wasadaptation . This means that some traits are passed on to new generations and become common within the population, like the long neck of the giraffe. This doesn't happen overnight, it takes time for these traits to spread throughout a population.

So, what does this mean for natural selection and genetic diversity? Let's find out.

State three reasons for preventing food spoilage​
bogdanovich [222]

Answer:

1) Refrigerate or freeze

If you freeze or refrigerate the food, the bacteria or whatever organism growth will slow down in the food by a Greta amount due to the coldness. Refrigerate might be a temporary food soteage for like a week or 2/ month max. While freezing will just freeeze the bacteria and mold on the food which can be stored up to 3- 12+ months even. But then again it will be most likely flavorless by the end or have no nutrients value. You can stores mik in the freezer for a while but its not recommended to taste, same for other thing syou usually see in the fridge, eggs/ vegetables/fruits/ milks/ yogurts/ etc.

2) No moisture, no water of any kind (drying in the sun or salted)

So every living thing we know of needs water. Including bacteria and mold. Without water, theres no place to thrive. No place to thrive means no bacteria and food is safe for a good amount of time. Dried foods can last a really long time, sure some types are really unpleasant but its edible. But you can’t techincally “dry” meat since it will be A whole nest for flies before it even reaches the halfway mark. You can slat it which will lessen he time but still really efficient. Salt absorbs water and breaks down any type of Stuff. Its like a mini acid.

3) Canned good and no air access (Pressurized/ controlled container)

This is done by putting all your favortie food in a metal container. With no air access, the bacteria or mold in the food already in can’t escape and new ones can’t get in. THe can then is boiled to a certain tempature where then the bacteria dies. Now the food can even be perishable stuff like meat (most common fishes), fruits and even a nice can of liquid soup. Nothin g can get in. Nothing can get out but nothing CAN get out becuase eveythign is dead. Canned food can last REALLY LONG, good for long term expeditions without a fire or food.
