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.

A difference in an inherited trait of an organism that may lead to new species?
variation
Difference between adaptation and natural selection?
Adaptation are the physical or the behavioral traits that make an organism better fits to its environment while the Variation usually comes from random mutations. Mutations are iniatially cause by a new heritable traits.
What are the 4 factors of natural selection?
1. All populations have genetic variation 2. The environment presents challenges to successful reproduction 3. Individuals tend to produce more offspring than the environment can support 4. Individuals that are better able to cope with the challenges presented by their environment tend to leave more offspring than those individuals less suited to the environment doIndividuals better able to adapt to changes leave more offspring.
How do you xxplain how the hitchhicker's thumb trait is determined using the following words allele domnate recessive homozygous heterozygous?
basically, the hitchhiker's thumb is a physical characteristic that is inherited from your mother and/or father. when you were conceived, your mother gave you some of her genes, and your father gave you some of his. the hitchhiker's thumb is either a dominent or recessive trait. It if is dominant, you could have a heterozygous parent and still have a 100% chance of inheriting it. If the hitchhiker's thumb is recessive, you must have both of you parents homozygous for the gene to have a 100% chance of inheriting it. The alleles are either HH (homozygous dominant), Hh (heterozygous), or hh (homozygous recessive). H H << if the thumb is dominant trait, you have a 100% chance of getting it H HH HH << if the thumb is recessive trait, you have a 0% chance of getting it h Hh Hh
A trait that is hidden?
The trait that is hidden is recessive trait.
A variety of a trait improves an organism's survival enabling it to produce more offspring than other members of the population then the trait is said to be what?
it is said to be fit
What does a mutation help with?
mutation help increase our chance of survival. By giving an non-existing gene or trait to an individual of a species population. This special gene can either be passed on or extinct. The special gene will pass on if the gene have proven it is useful and will extinct if its not. Overall, mutation help all life survival in the ever-changing environment and challenge they face.
How does evolution start?
Evolution generally starts when a species is under environmental stress. As long as food is plentiful, predations not too common and individuals can live long and healthy lives, most individuals are generally able to pass on their genes. When life becomes difficult, then those individuals with a trait that gives them a greater chance of survival will be more successful in passing on their genes. Then, from their offspring, any individuals that have acquired that trait to a greater degree, or acquired some additional trait that assists in survival, will be more successful in passing on their genes. Slowly over many generations, a new variation, then a new subspecies, then a new species can evolve.
What describes adaptations?
A trait that is beneficial to survival.
What is known as adaptation?
A trait that is beneficial to survival.
What is the central force in evolution?
There is no central force, except that anything which does not hinder a gene's chance of reproducing will allow whatever species that gene belongs to live on. If a trait helps a species to survive, that trait will be "selected". Look at it this way, if a particular trait means that some members of a species is less likely to breed than other members, that trait will die out eventually. This could mean that lions which have shorter claws than their fellows, or cheetahs which can't run as fast as their fellows will go hungry, and be less successful in having and rearing cubs which carry their genes. That is not so much a force driving evolution as a force culling those members of a species which are "less fit" for survival than their fellows
How do changes at the DNA and gene level change populations to eventually form new species?
I think you're talking about genetic mutation... If the trait is dominant then it will be spread to its offspring and if it doesn't hinder the offspring's survival then the trait will continue to be passed on to new generations.
Traits that improve the chance for survival?
It can be almost anything: a trait that allows an individual to run quicker, to hide better, to metabolize food better, to defend better against diseases, etc.
Can one sibling have the trait and the other not have the sickle cell trait?
Yes. There is a 1 in 4 chance that a child can contract sickle cell with the remaining having a chance to get the trait or being normal.
Are big ears a dominant trait?
Big ears in some species are considered to be a dominant trait. In other species having big ears is a recessive trait.
An individual heterozygous for a trait and an individual homozygous recessive for the trait are crossed and produce many offspring?
The offspring has a 50% chance of the dominate trait (while being heteroygous) and a 50% chance of having the recessive trait ( homozygous recessive).
What would the offspring most likely be if an individual with a heterozygous trait and an individual with a homozgous recessive trait crossed be?
The offspring would have a 50% chance of being heterozygous and showing the dominant trait and a 50% chance of being homozygous for the recessive trait.
