Appendages
What is an appendage?
The external part of an organism with a specific function or appearance.
Is blue eye color recessive or dominant?
Recesssive
How does selective breeding and biotechnology change genetic makeup?
They change the genetic makeup to be completely modified or to create GMO crops and plants to produce for the needs of humans.
What does vascular mean in the body?
The circulatory system, which is made up of blood vessels to carry blood to the body.
What are fungi?
They are eukaryotic organisms that include microorganisms such as yeasts, molds and mushrooms.
True or False:
All organisms or living things have visible appendages.
False.
Single-celled organisms -like bacteria- don't have visible appendages. Appendages on these organisms may refer to a pili or flagella on the cells surface.
If a family member has a disease, will the genes be passed down to the child? Why?
Yes. There is a 25% chance of the child getting the disease or a 50% chance of being a carrier of the disease.
Are GMO’s a result of biotechnology?
Yes! Humans modify crops to manipulate crops DNA. Tomato plants for example, are modified to produce more tomatoes than a typical vine.
What does vascular mean in plants?
It transports water and nutrients throughout the plant.
What is a Protista/Protist?
A simple eukaryotic organisms that are neither plants nor animals or fungi. Protists are unicellular in nature but can also be found as a colony of cells.
What are the 4 types of appendages?
1. Straight- shape
2. C-shaped
3. T-shape
4. L-shape
What makes genes recessive or dominant?
The interaction between the alleles of the genes is present.
How can biotechnology but not selective breeding change the genetic makeup of organisms?
Biotechnology only changes one gene, while selective breeding changes thousands of genes.
What does non-vascular mean in both plants and animals?
That there is no system to transport or carry important things to the body or plant.
What is the difference between abiotic and biotic?
Biotic factors are living things within an ecosystem; such as plants, animals, and bacteria, while abiotic are non-living components; such as water, soil and atmosphere.
Which animals have a tough exoskeleton that is joined by appendages?
Arthropods
Why are dominant genes more dominant than recessive genes?
If more than one gene is present the dominant gene is most likely to be on top.
Is selective breeding man-made or natural?
It is both. Natural selective breeding is when an animal needs to adapt to a new environment naturally, and artificial breeding is when humans choose what animals are bred together.
Do all animals and organisms have a vascular system?
No. Some organisms rely on their cell membranes to transport necessary nutrients and gases to the organism.
What are herbicides?
They are chemicals used to manipulate or control undesirable vegetation.
Are appendages and limbs the same?
No. Limbs are a jointed part of the body, while appendages are projecting from the body.
How many alleles does a child inherit?
We inherit one allele per gene.
What are some examples of biotechnology?
1. Agriculture
2. Medicine
3. Food
4. Forensic science
5. Biofuels
What animals are included in the non-vascular system category?
1. Jellyfish
2. Planarians (flatworms)
3. Sponges
What is the difference between acquired and inherited genes?
Acquired genes are developed and inherited genes are traits passed down from parents through DNA.
