Evolution is the change in allele frequency over time in a population of organisms.
Alleles are different molecular forms of the same gene and when their frequency changes in a population it indicates " hard " inheritance has taken place; the only type of inheritance that leads to evolution. Building bigger muscles during you lifetime can not pass the bigger muscles on to your progeny, thus mo evolution in any population.

Why was Lamarck's theory of evolution not eccepted?
Not well supported by the evidence and basically just assertion. Lamarck asserted that acquired characteristics, such as muscles developed during one's lifetime, were heritable. They are not. He also asserted that an organism had a " desire " to evolve. This was also not true.
Which is true about adaptions?
They are passed along to offspring.
What was incorrect about Lamarck's hypothesis?
Lamarck proposed the idea of acquired traits being passed on to offspring, known as the inheritance of acquired characteristics. However, this concept has been proven to be incorrect through the science of genetics, which relies on the understanding of DNA and how traits are inherited through genes, rather than through an organism's interactions with the environment.
How is evolution associated with DNA?
Evolution Is not true period. God created everything and all of his creation has a certain purpose. In Genesis 1: 1 it says: God created the heavens and the earth. So, Evolution pretty much has nothing to do with DNA. Read your Bible, its a great book with lots of knowledge!! :)
What did lamarck think evolution involved that caused his ideas to be incorret?
Lamarck believed that traits acquired by one individual, will be immediately passed down on it's descendants. FE: If your father was a smith, you will have stronger muscles and bigger hands. Which is not true because evolution like that happens over thousands maybe millions of years and genetic changes are only expressed if the mutations occur in the DNA of the reproductivecells (spermproducingcells etc) Note: Lamarck has proven to be right by scientist nowadays in the point of genetic expression: Children of people who survived the Hunger Winter in Holland of 1944 have more chance on heart diseases and become thicker more easily. This change is directed to the fact that certain events can activate certain genes, thus stating that Lamarck's theory isn't entirely wrong
What is true Individuals are constantly evolving. Populations are constantly evolving. Evolution involves descent with modification. Acquired characteristics lead to evolution.?
Individuals are constantly evolving - False. Populations are constantly evolving - True. Evolution involves descent with modification - True. Acquired characteristics lead to evolution - False.
Why was Lamarck's theory of evolution not eccepted?

What role did Lamarck think acquired characteristics played in evolution?
Lamarck put two ideas into his theory of evolution thought to be true in his time. 1. Use and disuse - people lose characteristics they don't use and keep the other ones . 2. Individuals inherit the traits of their ancestors. So instead of the environment selecting traits, he said that the species selected the traits.
Is it true or false that traits are the characteristics of living things?
True. Traits are the specific characteristics or features that living things exhibit, such as eye color, height, or behavior patterns. These traits can be inherited or acquired through environmental factors.
Which of Lamarck's ideas turned out to be true Which turned out to be false?
Right: adaptions to environment wrong: acquired traits are passed on
What must be true of all characteristics for it to affect evolution?
For a characteristic to affect evolution, it must be heritable, meaning it can be passed down from one generation to the next. Additionally, the characteristic must influence the survival and reproductive success of individuals in a population. These two factors are essential for natural selection to operate and lead to evolutionary change.
A change in gene frequency in a population over time is a foundation of biological evolution true or false?
True. That is the definition of evolution.

Is this statement true or false evolution involves descent with modification?
True.
Is the land east of the Appalachian mountains acquired as aresult of the civil war true or false?
YES this is true in most situations . HOPE i helped 😄
What is true of cuba?
the united sates acquired cuba as a protectorate
Is it true or false when Darwin returned to England he rushed his thoughts about evolution?
True
