A Venus flytrap is a producer. You see, the flytrap does not really EAT the insects that it catches. It decomposes them and uses their chemicals like fertilizer. These plants are designed to live in very poor soil, so they cannot get the chemicals they need for their biological processes from the soil. Thus, they get t...
The 3rd Edition of Biology was significantly revised and updated. Some of the updates include: * Updated content to present the most current science * A reorganized structure of the information, which helps students logically progress through their biological studies * Experiments which have been updated or rep...
No. It is change in chromosome number. If a gamete has 2 alleles for a trait, it must have 2 chromosomes for that trait. When that gamete joins with another gamete, the result will be three chromosomes, which is one too many. Remember, each normal gamete carries one chromosome per pair, and thus has one allele per trai...
**We recommend biology in the 9th grade for several reasons:** * Taking biology at the same time as algebra will allow all of the prerequisites for later science courses to be met. * Science-oriented students should have at least one college-level science before they head to college. By taking biology in 9th, che...
The rubbing alcohol pulls the DNA away from all of the other junk. Before you put the alcohol in, the DNA is mixed in with the pulverized onion, water, meat tenderizer, soap, etc. To make it easier to see those thin white wisps of DNA, you need to separate it from all of the other junk. DNA is more attracted to alcohol...
Anacharis has the common name of Elodea. If your local pet shop or aquarium store do not have Anacharis plants, ask for Elodea plants. If you can’t find that, just find the thinnest leaf you can. Your goal is to have a leaf thin enough for light to pass through it. ...
We recommend algebra and biology together because biology is a freshman-level course, and algebra marks the spot at which a student is at a freshman level when it comes to science and math. If your student is READY for algebra, he or she is, most likely, ready for biology. Taking biology and algebra together ensures t...
You will need to use dried split peas or lentils for this experiment. You should not cook them beforehand since cooking or freezing ruins the DNA. ...
**Multiple seeds form in many ways.** 1. In multiple fruits like pineapples, several flowers come together to form a single fruit. Thus, there are multiple seeds because multiple flowers are involved. 2. In berries, you typically have several carpels per flower, each of which might have several ovules. 3. In drup...
**This course has 3 kinds of labs:** 1. Household (15 labs) 2. Microscope (19 labs) 3. Dissection (4 labs) If you want to do ALL of the labs, you will need a microscope kit that includes a high quality high school microscope along with the slide set. You will also need the dissection kit. ...
