Answer 1
Answer:

Answer:

Based on similar appearance - traditional

Based on evolutionary relationships-  modern

Known as cladistics- modern

Known as Linnaean classification- traditional

Explanation:

Linnaeus was a Swedish Botanist who was the first to classify organisms based on the structural similarities which organisms had. This method of classification came to be known as the Linnaean classification. Organisms which had more closer resemblances in structures and features had more groups or taxa in common.

The modern system of classification depends on the evolutionary history of organisms. It determines which organisms are more closely and have common ancestors in the past.

How does natural selection change the frequency of genes or traits over many generations? Biology students conducted an experiment mimicking genetic variation and coloration. Students used different colored beans to represent animals that might be prey: mice, for example. A student in each group was the predator: a hawk. Beans (mice) were randomly scattered on multicolored floor tiles, each color within four tiles. The hawk collected mice (beans) for 10 seconds. Mice not eaten reproduced. Three generations of data a shown in the table. All BUT ONE could be a reason for the color variation in the mice. That is A) meiosis. B) mutations. C) genetic variation. D) asexual reproduction.

Answers

The answer would be D) asexual reproduction.


Asexual reproduction will produce a offspring that has the same genetic material with their parent. That mean the offspring will have the same genetic that code their parent color, thus their color is the same as their parent. Other option will allow the offspring to have different genes, so the offspring could have different color.

Answer:

D. asexual reproduction.

Explanation:

Asexual reproduction results in genetic sameness, not genetic variation.

Which of the following is not a required process for the survival of animals? A. Elimination of waste B. Movement C. Response to stimuli D. Absorption of nutrients and oxygen

Answers

Answer:

B. Movement

Explanation:

Movement is not a required process for the survival of animals.

This means that animals can survive without moving.

For example, during hibernation, a snake survives resting in a particular place without movement.

If a person's movement is confined to zero, the person can still survive, but if absorption of nutrients and oxygen stops, then the person shall die.

There are three major groups of mammals, categorized on the basis of their _____. see concept 34.6 ( page 739)

Answers

There are three major groups of mammals, categorized on the basis of their method of reproduction. Monotremes lay eggs to have children instead of having the mother bear them. The second type of mammal is the marsupial, which are non-placental animals who carry their young in their pouches. Eutherians are the third group who are placental mammals.

Why is ability to adjust conclusions were necessary important to critical thinking

Answers

When new information leads to new and different conclusions, it is important to be able to adapt to the most up-to-date conclusions. If conclusions are rigid and fixed regardless of any new information that may come to light, then they are not truly based on the facts under discussion.
