Which of the following is a reason why Lamarck’s hypothesis was wrong? (More than one choice may apply).

Acquired traits cannot be passed down to offspring
Evolution is just a theory
Organisms can not gain a trait just by wanting or needing to have it
The ancestors of giraffes didn’t have short necks

Correct Answer(s)

A. Acquired traits cannot be passed down to offspring
A. Organisms can not gain a trait just by wanting or needing to have it

Explanation

Lamarck's hypothesis was wrong because acquired traits cannot be passed down to offspring. This means that if an organism develops a certain trait during its lifetime, that trait will not be inherited by its offspring. Additionally, organisms cannot gain a trait just by wanting or needing to have it. These reasons undermine Lamarck's idea that traits acquired during an organism's lifetime can be inherited and lead to evolutionary change.

A mass extinction (a bunch of organisms died out) occurred according to this rock layer. In what layer did this occur?

B
C
E
F

Correct Answer

A. E

Explanation

The correct answer is E. This can be inferred because the question states that a mass extinction occurred according to this rock layer. Therefore, the layer in which the mass extinction occurred must be represented by option E.

Choose the best answer:A porcupine’s quills is a characteristic that helps it survive. This is called a(n):

Tool
Trait
Adaptation
Defense mechanism

Correct Answer

A. Adaptation

Explanation

The correct answer is "Adaptation." A porcupine's quills are a characteristic that helps it survive. Adaptation refers to the process by which an organism adjusts to its environment in order to increase its chances of survival. In this case, the porcupine's quills serve as a defense mechanism, protecting it from predators. This adaptation allows the porcupine to thrive in its habitat.

Is the following an acquired or inherited trait?Baking a perfect green bean casserole

Acquired Trait
Inherited Trait

Correct Answer

A. Acquired Trait

Explanation

Baking a perfect green bean casserole is an acquired trait because it is a skill that is learned and developed over time through practice and experience. It is not something that is passed down genetically or inherited from parents or ancestors. This trait is acquired through observation, trial and error, and the accumulation of knowledge and techniques related to cooking and baking.

Is the following an acquired or inherited trait?the ability to grow a beard

Acquired Trait
Inherited Trait

Correct Answer

A. Inherited Trait

Explanation

The ability to grow a beard is an inherited trait because it is determined by genetics and passed down from parents to their offspring. It is influenced by hormones and the presence of certain genes, which determine whether or not an individual will be able to grow facial hair. This trait is typically more prominent in males due to higher levels of testosterone, although some females may also have the ability to grow a beard due to hormonal imbalances or genetic variations.

Is the following an acquired or inherited trait?the ability to grow a beard

Acquired Trait
Inherited Trait

Correct Answer

A. Inherited Trait

Explanation

The ability to grow a beard is an inherited trait. This means that it is passed down from one's parents through their genes. The presence or absence of facial hair is determined by genetic factors and hormones. Some individuals have a genetic predisposition to grow a thick beard, while others may have a genetic predisposition for less facial hair or none at all.

Is the following an acquired or inherited trait?having an ‘innie’ or ‘outie’ belly button

Acquired Trait
Inherited Trait

Correct Answer

A. Inherited Trait

Explanation

The presence of an "innie" or "outie" belly button is determined by the way the umbilical cord is cut and healed after birth. It is not something that can be acquired or changed throughout one's life. Therefore, the trait of having an "innie" or "outie" belly button is considered an inherited trait.

True or false: Lamarck influenced Darwin and other scientists of the time by introducing the idea that organisms can change over time.

True
False

Correct Answer

A. True

Explanation

Lamarck did indeed influence Darwin and other scientists of the time by introducing the idea that organisms can change over time. Lamarck proposed the theory of inheritance of acquired characteristics, suggesting that traits acquired during an organism's lifetime could be passed on to future generations. While this theory has been largely discredited, it was a significant contribution to the understanding of evolution and paved the way for Darwin's theory of natural selection. Darwin built upon Lamarck's ideas, incorporating them into his own theory of evolution by natural selection.
