Biology Excursion Question Using data collected on field trip and two named animals, explain the relationship between the distribution and abundance of these two organisms and the abiotic features of the rock platform. There is a close relationship between the abundance and the distribution of organisms living amongst the long reef platform. Abiotic features such as temperature range, salinity, Ph. levels, turbidity, water availability effect the distribution and abundance of aquatic sea creatures living in the area. Some of the organisms such as Tesseropora Roseas (Barnacles) and Knobbly Winks have different adaptations, which allow them to survive in these harsh conditions.
Associate Level Material Appendix F Natural Selection and Patterns of Evolution Worksheet Complete the worksheet writing 100- to 200-word short answers for each question. Format your references consistent with APA guidelines. 1. What is the direct evidence in support of the theory of natural selection? Include at least four examples.
Depending on if the cell is an animal cell or a plant cell. | | Cytoskeleton | Cytoskeleton has intercellular proteins that help the cell maintain its shape and with helps with movement. | The word skeleton in Cytoskeleton reminds me of the meaning. | K Key Idea | I Information | M Memory Clue | Ribosomes | Ribosomes are protein builders. | The word Ribosomes remind me of Ribs.
These bacteria can move quickly due to their corkscrew movement and ability to use flagella. 3. Bacteria is heterotrophs must
Some epithelia are relatively impermeable; other are easily crossed by compounds as large as proteins” (Essentials of Anatomy & Physiology, Fifth Edition. 2010 pg. 94). 3. Provide sensation.
These types of animals usually tend to live in a more stable environment because their internal body needs to match their external living environment. The second way animals can regulate their osmotic concentration is by being an osmoregulator. These animals are independently able to maintain their salt level in their internal tissues regardless of the external environment’s solute (Campbell, 2008). Most marine invertebrates are osmoconformers and for them to survive in a hyperosmotic environment, an osmoconformer which is hyperosmotic to the environment must discharge excess water (Campbell, 2008). If the environment was hyperosmotic then an osmoregulator must intake water in order to survive (Campbell, 2008).
Chapter 6 Skeletal System: Bones and Bone Tissue ! 1. Important functions of the skeletal system include ! ! a. protection of the brain and soft organs.
(C) The organisms act as the foundation of the restricted food chain in a manner that is comparable to the role of the phytoplankton. (D) The ability of the ocean depths to support biological life is the result of the interaction between the phytoplankton and the organisms. With improvements in the design and function of unmanned submersible technology, scientists have marine vastly expanded their One of capacity the to accumulate data regarding the less-accessible environments. most significant discoveries relates to the role played by underground vents, fissures in the crust of the ocean floor that expel
The joints give the body flexibility and allow movement to occur. Bones: An Overview * Identify the subdivisions of the skeleton as axial or appendicular. * Axial – bones that form the longitudinal axis of the body - skull, vertebral column, ribs, sternum * Appendicular – bones of the limbs and girdles – all others * List at least three functions of the skeletal system. * Support – framework that supports and anchors soft organs * Protection – protect soft organs * Movement – place for skeletal muscles to attach and use bones as levers to move the body * Storage – fat is stored in internal cavities, also stores minerals such as calcium and phosphorus * Blood cell formation – aka hematopoiesis – occurs within the marrow of certain bones * Name the four main kinds of bones. * Long bones – longer than wide with shaft and heads at both ends made mostly of compact bone (dense and looks smooth and homogeneous) – all bones of limbs except wrist and ankle bones * Short bones – cube-shaped and contain mostly spongy bone (small needlelike pieces of bone and lots of open space) – bones of the wrists and ankles, sesamoid bones (form within tendons), and patella
The blowhole of a sperm whale “is found far forward on the left side of the head with a spout that comes out at a sharp angle from the head and toward the left” (Brownell 682).Sperm whales have a wrinkled appearance (Brownell 682).“They has 18 to 25 peglike teeth one each side”(Wursig 258). The “adult male sperm whales measure up to 36 to 65 feet” while the “adult female sperm whales measure up to 28 to 41 feet” (Brownell 682).“Almost all sperm whales live only in tropical and mild water” (Wursig 258).Their daily intake of food consists of large squids, “certain fishes, such as cod, skate, barracuda, and shark”(Wursig 258). Another type of toothed whales is the beaked whales.Beaked whales “have a beaklike snout and only two or four teeth in the lower jaw” (Wursig 258) and “the upper teeth are absent or vestigial” (Brownell 682a). “Beaked whales are of medium size,” (Brownell 682a) “some kinds grow only about 12 feet long, but others reach 42 feet” (Wursig 258).“There are 18 known species of beaked whales” (Wursig 258). “Beaked whales live in all the oceans”(Wursig 258), but some of the beaked whales “species live in the deep waters” (Wursig 258).
