Their litter sizes range from five to twenty babies. The babies are born "alive" and not in eggs, although they hatch in eggs while still in the mothers before they are born. They are born in August and early September. It takes these young snakes around three to four years to reach sexual maturity and most females only reproduce every other year. If food is scarce, she
In a type three survivorship curve, a very large portion of the cohort is killed within the first few weeks of life (Natural Mortality Lab). C. Chyros and S. hispidus are economically important species as a food source. C. chrysos serves as a source of bait for other fishes. Both the blue runner and planehead file fish species eat plankton and associated matter (Rooker et al.

For each level of green crab and replication, I watched the experiment on a 70-week time span. 3. Results & Discussion I HYPOTHESIS THAT AN INCREASE IN GREEN CRAB WILL CAUSE AN INCREASE IN THE CORAL WEED. RESULTS: Table of the effects of Green Crab on Coral Weed in the tide pool off the Washington State coast. Amount of Green Crab at the beginning of each simulation | Green Crab | Coral Weed | 0 crabs | MEAN: 36 | MEAN: 190 | | 28 | 193 | | 33 | 173 | | 41 | 188 | | 43 | 206 | | 33 | 189 | 10 crabs | MEAN: 87 | MEAN: 213 | | 84 | 189 | | 79 | 213
6. Repeat step 5 four times. Data/Observations: Conclusion: Recall: We did a lab to learn about how the mass of an egg changes when it is put in different substances. Explain: We recorded the masses of two eggs every 15 minutes. One was put in water while the other was put in corn syrup.
These little fellows are found higher in the intertidal area. Watch for them in tide pools, under rocks, and under clumps of seaweed. They're very common here. Lower in the intertidal, you'll see the granular hermit crab (Pagurus granosimanus). It has red or orange antennae, lacks hair, and its claws seem rough or grainy.
These eggs are white in color. One egg can barely be seen by the naked eye. In about 4 to 20 days, the eggs will hatch and the beetle will begin the next stage which is called larva. The main goals of the larvae is to eat and grow. This stage lasts from 90 to 114 days.
If necessary, round the result to the nearest tenth. 38) 39) How many liters of 80% hydrochloric acid must be mixed with 40% hydrochloric acid to get 15 liters of 65% hydrochloric acid? Write your answer rounded to three decimals. 39) 40) If (9, -9) is the endpoint of a line segment, and (12, -10) is its midpoint, find the other endpoint. 40) 41) It has been determined that the number of fish f(t) that can be caught in t minutes in a certain pond using a certain bait is f(t) = 0.22t + 1, for t > 10.
In the first several days of life, most newborns lose 5 to 7 percent of their body weight before they adjust to feeding by sucking, swallowing, and digesting. Then they grow rapidly, gaining an average of 5 to 6 ounces per week during the first month. They have doubled their birth weight by the age of 4 months and have nearly tripled it by their first birthday. Infants grow about 1 inch per month during the first year, approximately doubling their birth length by their first birthday. Growth slows considerably in the second year of life (Burns & others, 2013).
10. Repeat the entire procedure with the four other eggs. Plot the densities for all five eggs on a chart. How much variation in density is there from egg to egg? Background Research- How Salty Does the Sea Have to Be for an Egg to Float?
