Which adaptation is most helpful to a mammal that lives underground like a mole?
Second to bats moles are the animals most known for living underground. These small cylindrical mammals have become well-adapted to life underground. They have extremely tiny ears velvety fur small eyes short hind limbs and large paws that aid in digging.
How does the environment affect organisms?
Most plants and animals live in areas with very specific climate conditions such as temperature and rainfall patterns that enable them to thrive. Any change in the climate of an area can affect the plants and animals living there as well as the makeup of the entire ecosystem.
How might the environment influence the way in which a certain species evolves quizlet?
Species adapt to fit their environment because a species environment is what selects for traits that are fit or less fit. … Process by which a single species or small group of species evolves into several different forms that live in different ways rapid growth in the diversity of organisms.
Who believes that giraffes have long necks?
In the case of a giraffe Lamarck believed that giraffes once had short necks that got progressively longer as members of each subsequent generation stretched their necks as long as they could. In doing so Lamarck believed that each generation would grow slightly longer necks and pass that trait onto their offspring.Jan 16 2018
How does the survival of the bunnies explain evolution by natural selection?
How does the survival of the bunnies explain evolution by natural selection? The survival of the rabbits showed that fitness depends on the environment. In this case the overall color of the environment favored a similar coat color.
What is the relationship between mutation natural selection and adaptation quizlet?
The result of natural selection. Adaptations usually occur because of mutations some mutations can help an organism survive better than others in the species without mutation. It allows organisms to survive reproduce and pass on DNA. This is the link between evolution natural selection and adaptations.
Does a mole have eyes?
Moles are small burrowing mammals. Their eyes are poorly developed but what they lack in sight they make up for in their sense of touch. All moles have very sensitive snouts and long clawed digits that they use to dig tunnels.
What are 3 environmental factors that can play a role in natural selection?
Natural selection occurs if four conditions are met: reproduction heredity variation in physical characteristics and variation in number of offspring per individual.
- Reproduction. …
- Heredity. …
- Variation in Characteristics. …
- Variation in Fitness.

What theory states that organs not in use will disappear?
Lamarck proposed that when an organ was not used it slowly and very gradually atrophied. In time over the course of many generations it would gradually disappear as it was inherited in its modified form in each successive generation.
What are some examples of environmental changes that could create selection pressures for a species?
Predation competition and disease are examples of selection pressures.
Does natural selection only act on heritable traits?
Natural selection only acts on the population’s heritable traits: selecting for beneficial alleles and thus increasing their frequency in the population while selecting against deleterious alleles and thereby decreasing their frequency. This process is known as adaptive evolution.
Why are only inherited traits not acquired ones involved in the process of natural selection quizlet?
Why are only inherited traits not acquired ones involved in the process of natural selection? You can’t pass on acquired traits you have to learn them. … Artificial and natural selection are similar because they both have organisms that are evolving.
How do lizards survive in the desert without water?
Ever wonder how animals adapt to the lack of water in the scorching desert? While some animals have developed ways of extracting water from the food they eat or reducing water lost through evaporation desert dwelling lizards don’t drink water at all they absorb it through their skin.
What will happen to a lizard in a cold environment?
Without external heat sources all reptiles — snakes lizards turtles and tortoises — become hypothermic meaning their body temperature declines. As a result they become less active their digestion slows their immune system doesn’t function properly and they become susceptible to secondary infections.
How do moles adapt to their environment?
Senses. Crawling around in underground tunnels all day would leave most creatures with eyes and ears full of dirt. Moles however have a thin layer of skin over their eyes for protection as well as eyelids shaped to help push dirt away keeping their eyes clear. … This way dirt falls around instead of into them.
How do adaptations relate to natural selection?
In evolutionary theory adaptation is the biological mechanism by which organisms adjust to new environments or to changes in their current environment. … The idea of natural selection is that traits that can be passed down allow organisms to adapt to the environment better than other organisms of the same species.

What are individuals that are well adapted to their environment will survive and produce?
Individuals with adaptations that are well-suited to their environment can survive and reproduce and are said to have high fitness. Individuals with characteristics that are not well-suited to their environment either die without reproducing or leave few offspring and are said to have low fitness.
What are some environmental factors that can cause mutations?
Mutations can also occur as the result of exposure to environmental factors such as smoking sunlight and radiation. Often cells can recognize any potentially mutation-causing damage and repair it before it becomes a fixed mutation.
What eventually happens to a species when the environment changes and the organisms adapt?
Change in an organism’s environment forces the organism to adapt to fit the new environment eventually causing it to evolve into a new species. … They eventually become different species. Moreover if there is a change in the environment of one group it does not necessarily occur in the environment of the other.
What is most likely to happen to a species that is not adapted to its environment?
Organism that do not adapt or move die out or go extinct in the region where the major environmental change has happened.
How does environmental change affect the survival of a species quizlet?
Genetic variation allows natural selection to occur. How can an environmental change affect a population? When the environment changes some animals will die. … Natural selection is when a certain organism is picked to survive.
What is a lizards adaptation?
Lizards have a variety of antipredator adaptations including running and climbing venom camouflage tail autotomy and reflex bleeding.
Do individual organisms choose their adaptations or are the adaptations among organisms luck of the draw?
Note: this natural selection is not a conscious act- no one is choosing who survives and who doesn’t. Individuals had to inherit the “fit” traits by the “luck of the draw”. The other conditions of the organisms environment select who can compete better.

Which answer best shows an animal’s adaptation to the tropical rainforest?
Which answer best shows an animal’s adaptation to the tropical rain forest? Camouflage in a tree frog.
What occurs if the environment changes in a species is no longer able to survive?
What occurs if the environment changes and a species is no longer able to survive? The species becomes extinct.

How do mutations lead to adaptations?
Alternately if the mutation has a positive affect on the fitness of the offspring it is called an adaptation. Thus all mutations that affect the fitness of future generations are agents of evolution. Mutations are essential to evolution.
How are each of these lizards adapted to its environment?
How is each of these lizards adapted to it’s environments? They adapted by blending in with their surroundings.
How are heredity and natural selection involved in the process of evolution?
How are heredity and natural selection involved in the process of evolution? In natural selection nature selects and favors organisms for survival based on their heritable characteristics. … Convergent Evolution- organisms from 2 different ancestors evolve similarly because they both live in similar environments.
Why do lizards do push ups?
Lizards work out for the same reason a guy at the gym might: as a display of strength. And with lizards as can be the case with men the push-ups also mean “get out of my territory.” And a new study finds some lizards make a morning and evening routine out of the displays.

How can a species evolve through natural selection?
Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.

How does environmental change affect the survival of a species?
Climate change can alter where species live how they interact and the timing of biological events which could fundamentally transform current ecosystems and food webs. Climate change can overwhelm the capacity of ecosystems to mitigate extreme events and disturbance such as wildfires floods and drought.
Why are only inherited traits involved in the process of natural selection?
Inherited traits are influenced by genes which are passed on to offspring and future generations. Things not influenced by genes are not passed on to your offspring. Natural selection only operates on traits like earlobe shape that have a genetic basis not on traits that are acquired like a summer tan.
Why do lizards live in hot climates?
Lizards warm themselves using insolation and conduction. Insolation is the absorption of the sun’s rays and conduction is absorbing heat from the ground. If the lizard gets too hot he will move into the shade or a burrow to cool off.
How does the environment influence natural selection?
In a population the natural selection will favour the individuals with the higher fitness (In other words : the ones which have the best chances to survive and reproduce) in a given environment. … It means that for different environment one gene can give different trait values at the phenotypic level.
