Bio Lab Final Flashcards
This animal has venom that is 15X stronger than rattlesnake venom. Has an hourglass- shaped mark on the abdomen.
Black widow spider
This plant has is characteristic of the woodlands we saw in Bang’s canyon. It is an evergreen with small reduced scale-like leaves and blue female cones. It is commonly used to flavor gin.
Juniper
This fragile organic layer is a complex of living organisms including: algae, cyanobacteria, bacteria, lichens, mosses and fungi.
Cryptogamic crust
This plant has a mutually beneficial relationship with its pollinator. The plant has tough, sword-like leaves and large clusters of white flowers.
Yucca
This animal is a carnivore. It is unique in that you can find them at night with a black light. It is venomous.
Scorpion
This plant is characteristic of the woodlands we examined in Bang’s canyon. It relies primarily on a species of Jay to spread its edible seeds around.
Pinyon pine
This plant is adapted to dry climates. It stores water in its succulent pad. Both the pad & the fruit are edible.
Prickly pear cactus
This plant is an invasive grass species that spreads its seeds on the fur of animals. It can take over disturbed ground and can be a fire hazard.
Cheatgrass
This is a native shrub species that we saw in both the riparian and the upland ecosystems. It has 3-tipped leaves and is very aromatic.
Sagebrush
These type of organisms make their own food using the sun as an energy source.
Producers, autotrophs
This plant has jointed stems with small scaly leaves. The plant is one of the first primitive plants with a vascular system. The stems are very rough with silica in them and the stems are also hollow.
Horsetail, scouring rush
This plant is an invasive rounded bushy annual that breaks off at ground level and is blown around by the wind spreading its seeds everywhere. (Tumbleweed/ Russian thistle)
Tumbleweed, Russian thistle
This plant is almost completely edible. You can eat the roots, leaves and seeds. It always grows it wet areas and we saw it along the Audubon trail and up in Bang’s canyon.
Cattails
This tree is a non-native species. It is the 1st to produce seeds in the spring. It has a very high germination rate for its seeds. It has no native predators and grows frequently in disturbed areas.
Siberian elm
This small tree is frequently found along the Colorado River. It is a non-native species. It is very tolerant to salty soils and has pink flowers and small leaves. It has no native predators but scientists have found a beetle from Asia that is currently being used as a biological control.
Tamarisk
These are small round structures that are commonly found on the stems of Rabbitbrush. They contain the larvae from a species of fruit flies.
Galls
This animal is nocturnal and a carnivore. It frequently occupies the old nests of Magpies.
Great horned owl
This tree is dioecious. It is closely related to maple trees and you can tap it for syrup in the spring. It is a common native weedy species often found in wet areas.
Box elder
What is one example of an omnivore that could be found in Bang’s canyon?
Bear
This is type of system that is used at the Persigo wastewater treatment plant.
Conventional activated sludge system
What term describes organisms that do not require oxygen to survive?
Anaerobic
This is the amount of oxygen that is required by the micro-organisms to ensure digestion of the sludge.
BOD/Biological oxygen demand
How long does it take for the water to travel from the input line to the output into Persigo Wash?
14 hours
These animals are adapted to eat plants. Includes rabbits, deer and elk.
Herbivor
The wastewater is pumped into this building. The waste stays here for 2 hours and 90% of the sewage is removed.
Primary clarifier
The activated sludge from the final clarifiers comes here and is reduced by cannibalism.
Aerobic digesters
This is the last stage in the treatment of the water. The water flows through light tubes to kill remaining organisms.
UV light station
The fluid from the primary clarifiers come here. The fluid retention time is 6 hours and 8% of the waste is removed.
Aeration basin
What is produced by the micro-organisms in the Anaerobic digesters as a by-product?
Methane
Water is diverted into these tanks if there is too much liquid to handle at one time or if the incoming water is too toxic to be brought directly into the system.
Flow equalization basins
How many gallons of water does the treatment plant handle every day?
8 million gallons
What is the largest organ in the body?
Skin
Which layer of the skin is the outermost? Layer that primarily protects us from injury and pathogens?
Epidermis
These cells produce the pigment Melanin and protect us from UV radiation?
Melanocytes
What are the most common type of cells found in the epidermis of the skin?
Keratinocytes
This is a gland that produces an oily secretion called sebum. Found along the hair follicles.
Sebaceous gland
These are muscles that act to lift the hair shaft upright and result in goosebumps?
Arrector pilli muscle
What is the layer of the skin that provides insulation to the body and is composed of adipose cells?
Hypodermis
