Chameleons shift colors wherever they go. They are able to turn any colors or combine colors depending on where the environment is. What trait is being described?

The field of science is changing the lives of all organisms through technology and research. This is explained by ______________.

All organisms alive today have descended from simple cellular creatures billions of years ago. Biologists were able to identify and preserved some of the characteristics of that earliest organisms. This is associated in what theme?

The asexual reproduction where the organism splits into two separate organisms like in bacteria.

Flat worms (planarians) divides into two, leaving one piece headless and the other tailless each piece grows the missing body parts.

A new individual grows on the body of its parent like hydra and yeast.

Reproduction in animals that involves production of new living organism by combining two gametes from different organisms, one male producing motile gamete that must fuse with the egg cell from female organism.

This is when an organism possesses two reproductive systems and are referred to as monoecious

Which of the following describes as a process in which animals with desired characteristics are mated to produce offspring with the desired traits?

Which of the following is a process of creating an organism that has an exact genetic copy of another?

Which refers to a technique in artificial selection that involves propagation of organisms with desired traits?

Which refers to a process where a DNA is cut out from one organism and put into another organism?

Which describes a technology used in genetic engineering where DNA molecules from two different species are combined?

What do you call the process of manipulating genes to alter an organism’s genetic make-up?

Which among the choices is the other term for genetically modified organisms?

Which among the choices below is used for improving human health condition by producing vaccines and pharmaceuticals?

Which is referred to as the ethical implications and applications of the process of genetic engineering?

What do you call the transgenic organism that has the taste of grapes but looks like an apple?

Which system delivers oxygen and nutrients to every cell in the body?

What can you infer about carbon dioxide from the function of the respiratory system?

The circulatory system and the nervous system both:

What is the main function of your stomach?

Which body system is responsible for taking in oxygen and getting rid of carbon dioxide?

Which of the following is an example of the endocrine system directly interacting with the nervous system?

During the final stages of human gestation, receptors for the hormone oxytocin increase on the smooth muscle cells of the uterus. The release of the oxytocin during labor stimulates the smooth muscle tissue in the wall of the uterus. The vigorous contraction of the uterine smooth muscle helps push the baby through the birth canal so that delivery can occur. This process involves the interaction of which organ system?

Kidneys are part of the excretory system. They purify the impure blood and send it back to the rest of the body. Which system is mainly responsible for the transport of plasma to the kidneys?

What two body systems are most useful in getting nutrients from the food that you eat?

What two systems work together to provide body cells with a constant supply of oxygen while removing carbon dioxide waste?

According to his theory of evolution, organisms change during their lifetime to survive, then pass these changes to their offspring. Who is the scientist credited for this theory?

Which of the following refers to a change over time in the characteristics of a species?

Each living species has descended, with changes, from other species over time and as a result species today look different from their ancestors. Which theory describes this phenomenon?

Which of the following explains the difference in survival of individuals that reproduce in a particular environment?

Which of the following occurs when there is a change in genetic makeup of organism?

The Greek word phylon from the word phylogeny means ____________.

The Greek word genesis means ____________________.

Diagram that traces evolutionary relationships and connections among organisms

Lineages that evolved early from the root and remain unbranched

The point where split takes place

Which of the following is an example of environmental resistance?

Which of the following is NOT an environmental resistance?
