Kangaroos are uniquely adapted for survival in Australia, a country that suffers frequent droughts.
* The mother kangaroo spends most of her adult life pregnant, but in drought times, she has the ability to indefinitely "freeze" the development of the young embryo until food sources are replenished.
* The mother can also produce two different types of milk to suit the needs of two different aged joeys. She might have a more mature joey that spends less time in the pouch, while a very young embryo has attached itself to a teat. Each joey has different milk requirements - which the mother is able to supply.
* Kangaroos are able to travel long distances at a high speed, expending very little energy. They are very energy-efficient, and this is linked directly to the physical action of bringing their hind legs up with each hop. Every hop literally refills the lungs.
* Kangaroos have large, strong tendons in their hind legs which act as "springs". The springing motion requires less energy than running does, so kangaroos are able to bound for longer distances than other mammals with the standard four legs can run. They have strong back legs and elongated hind feet for bounding.
* Kangaroos are strong swimmers. Many parts of Australia are subject to seasonal flooding rains, but the kangaroo's body shape does not prohibit it from swimming. In fact, kangaroos have been observed swimming to offshore islands off the southern coast. This is the only time the kangaroo's hind legs move independently of each other.
* Kangaroos are more active in the cooler hours of the early morning and the late afternoon. During the heat of the day they are more sedentary, lying around quietly and chewing their cud.
* The teeth of the kangaroo are continuously being worn down by the tough grasses they eat. Instead of continuously growing, once a kangaroo's front teeth are worn down completely, they fall out, and the back teeth move forwards to take the place of the worn front teeth. Kangaroos have four such pairs of chewing teeth.
* Kangaroos have the ability to hear very well: kangaroos can twitch their ears independently around to determine the direction of specific sounds, much as a cat does
* They have long, strong tails for balancing.
These adaptations are the same for most species of kangaroos, including Red Kangaroos, Grey Kangaroos, wallaroos and wallabies.

Adaptations give organisms a better chance for?
Survival and reproduction in their environment by increasing their chances of obtaining resources, avoiding predators, and successfully reproducing. These adaptations help organisms to thrive and pass on their genes to the next generation.
How does adaptations improve the survival of a species?
Adaptations increase chances of survival for a species because the better prepared that species is to defend against attackers (i.e. humans defending themselves against viruses), the better chance that species has to defend against that type of attack again in the future and prevent the threat of that species' extinction.

How do adaptations contribute to the process of natural selection?
Adaptations are traits or characteristics that help organisms survive and reproduce in their environment. These adaptations can give individuals a better chance of survival and reproduction, passing those beneficial traits on to their offspring. Over time, through the process of natural selection, individuals with advantageous adaptations are more likely to survive and pass on their genes, leading to a population that is better suited to its environment.
What are any inherited characteristic that increases an organisms chance of survival called?
Adaptation."Darwin argued that fitness arises through a process called adaptation. Successful adaptations enable organisms to become better suited to their environment, better able to survive and reproduce. Darwin also used the word adaptation to describe any inherited characteristic that increases an animal's or plant's fitness for survival."-Prentice Hall Biology Text book.
Are adults or children given a better chance for survival from lymphoma?
The survival rate among children is definitely better than among older people.
What do you think has a better chance of survival a Euglena in an environment with no light or an amoeba in an environment with other organims?
An Euglena in an environment with no light has a better chance of survival because Euglenas are photosynthetic organisms that can make their own food using sunlight. Amoebas in an environment with other organisms may face competition for resources or predation, which could decrease their chances of survival.
What cell size has a better chance of survival?
A cell that hasn't been damaged.
Behavioral adaptations and instincts can increase an organisms chance for survival?
Yes, behavioral adaptations and instincts are beneficial because they help organisms respond effectively to environmental challenges, find food, avoid predators, and reproduce successfully. These adaptations are shaped by natural selection and have evolved over time to enhance survival and reproductive success.
What is the difference between helpful and harmful mutation?
a beneficial mutation in an animal, plant, cell or bacteria will allow it to have a better chance of survival and allow it to continue passing on its DNA in its offspring. a harmful mutation does the exact opposite it hinders the animals survival and will eventually lead it's species to extinction.
What is Behavioral Adaptations of Plants?
they are actions that a plant takes in order to increase its chance of survival. An example of a behavioral adaptation in plants are tropisms. Tropisms are the growth of plants toward sunlight.
Trait that improves a species chance of survival?
Adaptation is a trait or structure that improves an organism's chance for survival and reproduction. Benthos is organisms that live on or near the ocean bottom, sometimes attached to surfaces.
