Tissue and Homeostasis
What are the four types of animal tissue?
Epithelial, connective, muscle, and nervous
What type of immunity do ALL animals have?
Innate immunity
What are some costs of sexual reproduction? List 2
-finding a mate takes time/energy
-only half your genes get passes into the next generation
-half as many daughters as asexual
The study of behavior
What is the hierarchy of the different levels of ecology?
organismal -> population -> community -> ecosystem -> landscape -> global
What is adipose tissue?
-specialized loose connective tissue that stores fat.
What do cytokines and histamines do to help the body elicit an imflammatory response?
What is haplodiploidy?
Honeybees, ants, and a few other species reproduce both sexually (to form daughters) or asexually (to form sons)
What is Taxis?
When a stimulus causes the target to move towards or away.
EXAMPLE - when plants grow towards the sunlight (phototaxis)
The less trees there are the more CO2 that is left in the atmosphere causing climate change.
Which type of tissue has the proteins actin and myosin? What are the three subtypes of this kind of tissue?
Muscle tissue - skeletal, cardiac, and smooth
"Lymphocyte antigen receptors bind to specific parts of an antigen called epitopes. Leads to formation of cells that secrete a soluble form of the receptor, called antibodies."
What type of cell is being described by the quote above?
B cells - antigen recognition
B cells are one of the kinds of lymphocytes
Why is sexual reproduction advantageous in an environment that is constantly changing?
Sexual reproduction equals variation in the offspring, making them more resilient to a changing environment
In birds mnay males will create extravagant dances to attract females. Many of these dances are unlearned by the males and they come naturally. What are these dances an example of?
Fixed action pattern
Draw the three types of survivorship curves and give an example of an animal with this curve.
one - humans , elephants
two - squirrels , birds
three - sea turtles
Negative
What are the 4 characteristics of acquired immunity?
What are the three types of asexual reproduction? Give examples of each.
1) fission - Sea anemone: Divide in half; genetically identical
2) Budding - Hydra: New individual from existing individual
3) Fragmentation + Regeneration - Starfish (sea star): Detached arm can turn into a complete individual (some species)
What is the difference between proximate and ultimate causes for animal behavior?
Proximate deals with what direct stimulus or physiological mechanism causes a certain behavior.
Ultimate looks at how that behavior is adaptive and what the evolutionary history is of certain behaviors.
Compare and contrast R-strategist vs. K-strategists
R
K
Compare and contrast the endocrine system versus the nervous system.
What are the two types of T cells? How do they work in our body's immune system?
1) Helper T cells
-assist in both humoral and cellular immune response
2) Cytotoxic T cells
Daphnia is a microscopic aquatic crustacean. At certain times a female daphnia will reproduce without fertilization and create haploid offspring, but the same daphnia can also reproduce with fertilization creating diploid offspring. What process describes this daphnias reproduction?
Parthenogenesis
How far food is located away
Draw a graph depicting the [CO2] from 1958 to 2024 in Mauna Loa, Hawaii
Draw the seasonal variation too.
seasonal - positive january - july
negative july - december
1958 - 315 ppm
1996 - 355 ppm
2024 - 423 ppm
