A significant difference between the effects of the genetic information passed on from asexually reproducing parents to their offspring and sexually reproducing parents to their offspring is the*
Aphids, small insects that feed on the sap of plants, undergo asexual reproduction during the summer months. They produce eggs that are formed without the separation of chromosomes. These eggs do not need to be fertilized, and all of the resulting offspring are female.
The best explanation for all of these offspring being female is that*
The diagram below represents a form of cellular reproduction.
As a result of this process, offspring 1 and offspring 2 will have*
Female hammerhead sharks sometimes produce offspring by a type of asexual reproduction. These offspring*
The diagram below represents a technique used to produce carrots.
Which reproductive process determines the traits present in the cluster of cells?*
A student used a microscope to observe a single-celled organism. As he watched, it looked as if the organism split into two cells. He made drawings, shown below, of the organism over a short period of time.
Which process did the student record in his drawings?*
The paramecium is a single-celled organism that reproduces asexually. The offspring of a paramecium usually contain*
The ameba, a single-celled organism, reproduces asexually. Variations in an ameba would most commonly occur through*
When an organism reproduces asexually, it usually has*
Base your answers to questions 10 on the diagram below and on your knowledge of biology. The diagram represents a technique used by scientists today to maintain the genetic makeup of an organism.
Which graph below best represents the DNA content found in each cell in each of the stages in the diagram above?
The diagrams below represent two reproductive processes used by different organisms.
When compared to organisms that utilize process A, organisms that utilize process B would most likely produce offspring with*
An organism that reproduces asexually will have offspring that have*
Identify one way in which the process of growth of a human embryo is similar to the process of reproduction in a single-celled organism. *
Base your answers to questions 14 on the information and photograph below and on your knowledge of biology.
Transgenic (GMO) Tomatoes
The use of pesticides to control insects costs billions of dollars every year. Genetically modified organisms (GMOs) are an attempt to reduce this cost. Tomato plants that are genetically modified can make proteins that are poisonous to the insects that feed on them. Using these GMO tomatoes would reduce the need for the chemical control of insects.
Identify the process responsible for passing the gene for insect resistance in a leaf cell of a genetically modified tomato plant on to the cells that develop from it. *
A farmer planted two corn varieties, one of which was very tasty but had small ears, and the other one had large ears but did not taste nearly as good. The pollen from one variety was used to fertilize the other variety of corn. State one biological advantage this method of reproduction has over cloning. *
