Which statement regarding genes and evolution is true?A. If an organism has a mutation, it will be less "fit" (less able to reproduce) than other organisms.
B. Today's plethora of microorganisms is the result of an extremely brief period of genetic recombination events.
C. Mutations function to prevent the offspring of an organism from evolving.
D. Random, heritable genetic mutations are a source of genetic variation. This variation is necessary for natural selection to occur.

Answers

Answer 1
Answer:

The statement which is true regarding genes and evolution is as follows:

  • Random, heritable genetic mutations are a source of genetic variation. This variation is necessary for natural selection to occur.

Thus, the correct option is D.

What is Genetic mutation?

Genetic mutation may be defined as sudden, stable, and inheritable alterations in the genetic material of an organism. It is considered one of the most useful events for evolution to occur.

Random mutation takes time but they are the least effective and non-influential. Such type of mutations are easily heritable and induces genetic variation among individuals of the same species.

As a result of this, as time passes such mutations become a base for natural selection to occur and allow the favorable variation to survive and reproduce effectively.

Therefore, the correct option for this question is D.

Answers

Vertebrates that are endothermic are birds and mammals. Endothermic organisms are able to regulate their own body temperature while ectothermic organisms depend on the temperature of the environment. Birds and mammals are endothermic organisms. Fish, amphibians, and reptiles are ectothermic organisms.

If you are in an emergency and there is no space to the side to steer out of the way of a crash, __________.

Answers

The correct answer is controlled braking.

If someone suddenly pulls out in front of the person while driving, the natural reaction is to apply the brakes. Although, this is a good reaction if there is the adequate distance to stop and one applies the brakes accurately.

While in case of emergency stops, one should apply brakes in a way, which will maintain the vehicle in a straight line and permits one to turn if it becomes essential. For this, the person can use stab braking method of controlled braking.

In controlled braking, one applies the brakes as hard as one can without locking the wheels. There is a need to keep steering wheel movements very slight while attempting this. If one needs to make bigger steering amendments or if the wheels lock, release the brakes.

Which school of thought studies how cognitive processes help people and animals develop habits?a. psychoanalytic theory
b. functionalism
c. Gestalt psychology
d. behaviorism

Answers

The right option is b. functionalism

Functionalism is the school of thought that studies how cognitive processes help people and animals develop habits. Functionalism is a theory concerned with the nature of mental states where mental states are recognized by their functional role through its organization rather than by what they are made of. Functionalism maintains the standard objective that mental states are internal states of thinking creatures when compared with behaviorism.


Behaviorism is the learning theory that focuses on observed behavior. Believed that one's responses are based upon what goes on around them, and then in turn ultimately shapes one's actions. By figuring out what environmental stimuli trigger some habits or behavior, you can therefore change and remold reactions.
