Taxonomic Classification

Animals are placed in taxonomic classifications based on differences and similarities of their traits. If you know what critical traits to look for, it is possible to separate any animal into a taxonomic category. Download the document. (See attached file) The document contains a table with images. The images are examples

Lab

Laboratory 25- The Chordates 1. Describe characteristics for deuterostomes. 2. List phyla with deuterostomes. 3. List the subphyla of chordates and give an example of each. 4. Describe the general characteristics of echinoderms. 5. List and describe the four chordate characteristics. Structure Function notochord dors

Different Groups of Amniotes

I am studying Amniota and I was wondering if someone could explain to me the following concepts. I know that the features of Chordata are the notochord, dorsal nerve cords, gill clefts (except for Tunicata); segmented muscles and a post-anal tail. I know that developmentally we are related to echinoderms. Can you explain the

Q4 need concise answers

4. An investigator performed cytofluorimetric (FACS) analyses of a mouse strain called C.B20 and a spontaneously arising point mutant that arose in the same strain called "C.B20 scid." Splenocytes from each strain were stained with anti-IgM (green) and anti-CD3 (red), then analyzed. The proportion of cells falling into each phen

Biology

Some people argue that each individual animal has an intrinsic right to survival. Should this right extend to plants and microorganisms? What about the Anopheles mosquito, which transmits malaria? Tigers that sometimes kill people in India? Bacteria that cause typhoid fever? Defend your position. Is it right to use an

Animal Behavior

1.5 List threee types of evidence we have for genetic influences in the development of behavior and describe a non-human example that illustrates one of these tpes of evidence. 1.9 The evolutiont of flight in birds and the evolution of blood sucking by a moth inthe genus Calpe. Choose one of the above methods and describe how

Energy expenditure in resource management

Suppose a tree squirrel living in the conifer forests near La Grande eats seeds that it extracts from pine cones and fungi that it finds on the forest floor. Also, suppose that currently it takes an average of 2 minutes to find a cone and 4 minutes to find a fungus. It takes 10 minutes to break open the cone and eat the seeds an

Animal Adaptation

Think about gazelles, zebras, antelopes, and other large hooved animals living in herds on the plans of Africa where there are a variety of species of large mammation predators like cheetahs, lions, leopards, hunting dogs, etc. Visualize that you are a member of one of those prey species. Explain about the antipredator mechanism

Animal Behavior: Antipredatory Adaption

The terms below, tell how each function as an antipredatory adaption and give a non-human example. - bastesian mimicry - misdirection - chemical repulsion - surprise - disruptive coloration - removing telltale evidence

Territory and Home Range, Map Sense and Compass Sense

3, Below is the movement track made by a bacterium in a culture dish exposed to a heat lamp shining from the side. What kind of response has the bacterium made? 4. Differentiate (don't just define): a. Territory and home range - b. Map sense and compass sense - 5. In my paper on roost site selection by silver-haired bats

Animal Behavior - Offspring Dispersion

1. As this male and its mate search their territory for insects to feed their young they wander widely but are able to return straight back to the nest once they have found food. What ability are they using to do so? At the end of the first nesting period, suppose this male and its mate have successfully raised one son and on

Animal Behaviour and Ritualization

Define ritualization and give one example of the way a behaviour might be changed during this process. See attached file for full problem description.

Questions about animal behavior and learning

(1) Choose one of the following terms (imprinting, habituation or latent learning) and tell how this type of learning could be adaptive for a wild organism. (2) The two graphs [see attachment] show the results of testing 4 species of birds in a spatial task and a non-spatial task. Why are Clark's nutcrackers much better than

Biology - Biomimicry

Discover more about biomimicry techniques. You will create a presentation covering the following issues: what implication(s) does this have for our species?; how does this alter our thinking of the way we categorize organisms?; are we the first species in history to be directing our own evolution?; what are the implications for

Discussing the Actions of Birds, Reptiles and Aquatic Species

A. Lizards often lie in the sun in the mourning. Why? B. Basking sharks swim close to the surface of the water and appear to be sunning themselves like lizards. In fact, however, they are feeding on plankton. Why might a land-dwelling creature like a lizard need to sun itself, while a water-dwelling creature like a shark does

Bill Adaptations and Food Source

What are some of the BILL ADAPTATIONS and LIKELY FOOD SOURCES you might associate with the following habitats. Why would you expect to find this bill type? 1) Wetlands and shore birds 2) Lakes and open waters 3) Grasslands or Raptors 4) Oak wood land and/or Coniferous Forest

Claw, Leg and Foot Features

What are some of the CLAW, LEG, and FOOT FEATURES you might associate with the following habitats. Explain why these features would be realistic in consideration of the environment, food sources, environmental challenges the birds might face. 1) Wetlands, shore birds 2) Lakes, open waters 3) Grasslands full of rodents
