This section was hard to read and understand

Hair length is a factor for the fox and camel. Depends if the camel is dehydrated or not to have high internal temperature, but average the camel stays homeostasis.

starts with brushes and small insects, and bigger animals like rabbits eat it and foxes eat rabbits, so forth

Depends what kind of habitat they're in.

since they introduced the wolves into Yellowstone National park in 1995, there has been an increase in the ecosystem of trees grown, because the elk have to be in the grass to get their food, because there is not enough seedlings from trees. but when the wolves were introduced it made the elk scatter and become scared.

A few birds a part from the group to feel safer. other than that they form a flock to act like one individual to possibly get away from the predator.

Isolation within the species because they can exist in a certain area, but also be in a smaller area for themselves

They come from your genes, proteins, and physiology.

Depends on the maturity level of the species. and when it can produce offspring. There is more little ones than bigger or older ones. also variation between the age and the population because of the maturity level has to happen before offspring.

They need to survive so they communicate with each other to revive resources for survival.

Unicellular Bacteria

Yes, ticks can use their saliva to spread bacteria to the host which is the human. and then it can spread inside of the human, and flushed down the toilet, and then can restart their life

going through digestion of food takes a complex step soon after going the stomach, this is were all the nutrients are absorbed and taken to the rest of the body

Nutrients from the environment and plus rainfall together get stuck and that's when plankton likes to use to grow its bacteria and spread.

Nitrogen Fixation

Cell division is important for single cells to create a large number of that cells species. Going through Mitosis

This means that the plant had adaptive radiation due to being close to the water, and in water at somepoints, but still survived very well on both land and sea

Don't know the exact date, but you can see how closely related other plants are together with the graph. The scientist figured that spores in the plants can determine how and when plants could shape the existence of wild animals surviving longer

Yes you can even with the slightest change you still can determine the species with the evolutionary tree

So for the evolutionary tree. Does this mean that if you create a "v" shape and put two species on top, and then branch them off from within the two, they all share the common ancestor? How do i know who is more related to each other than others?

The saliva from the tick can carry many diseases that can be transferred to the host (humans) witch causes sickness and other symptoms

Because they need algae to survive. without this they are just a bleached exoskeleton that are desperate and ready to die

I'm not quite sure what the dot sizes means in figure 21.3. I understand that pollination from the moths, and the visits but the different sizes of dots, I'm not sure

Scientist found that chimps have the same shape of head as humans. So through the evolutionary tree you can determine that the chimps and humans share closely ancestors

Yes, in fact they do, because the male guppies have gone close to the predator, and have survived. Survived to tell their mate, and possibly protect them. So in this case Yes females prefer bold males

Firstly, you have to understand what the graph is telling you. There may be errors in the graphs that might through you off, but very closely could be something else

Natural causes such as wind, heat, cold, mountains, etc. can separate a species that once became one, but over time and isolation they will slowly grow apart from each other.

I know that in Canada people have to pay a tax due to the pollution of the air, are try to fix this problem.

So the prey is scared? or are the guppies scared? which one swims away from the other? sort of confusing here

Yes, and no, because humans are another type of species that are competing to survive as well. If we don't want something, something else will have it instead. But since human population is growing there are going to be less for other species and down the road will become extinct.

1. Find relative proportion of each species 2. then find natural log of each, 3rd. Multiply each by natural log. 4th is to add the three together.

Yes, chemical communication is used to block and defend itself from potential in this section, according to the moths and their offspring.

In this case the Lizards want to be in homeostasis state which means they don't want to get too hot, or too cold while they are at the ants nest feeding. Plus with this experiment the scientist only followed the Lizard around for only 1 day.

Some species intercept information transfer between members of another species. Most of the time predators will hear vocalization from a prey and go after them to a sound that they prefer.

Temperature is a big factor because animals want to stay at a certain temperature just like humans. We don't like it when it's too cold or too hot, we like it just right. And that makes the animals feel comfortable to try to find a mate faster. Mid day is best. Too early in the morning they are cold and tired. And too late in the day, they are also tired and ready for bed.

Humans communicate with each other by visual and audio. But some people can't hear so they depend on visual. Sometimes information that is sent doesn't mean what that is being received. If you have a large group of the same species they will understand each other. But if you have few different, the different ones will not understand.

We need annual vaccination because science every year makes changes. Scientists make these changes to find out what works the best and what works the worst. Obviously on the hospital aspect it's a good way to keep jobs open while always improving equipment.
