Part 1:

You need to include a

• Title: Lab- Interdependence of Organisms

• Purpose: Measure the effect the worms have on plant growth in the population

• Question: Will adding worms to the soil affect the growth of plants?

• Hypothesis: If plants grow in soil containing worms, then the plant growth will be greater because worms help decompose organic matter and distribute it through the soil in a form that plants can use.

• Variables:

Independent- number of worms

Dependent- plant growth

Constant- the type of plant, amount of sunlight, etc.

Control-

Part 2: Materials and Procedure

Supplies- two trays, lima bean seeds, worms, location with sunlight, black marker, meter stick, graduated cylinder, water

Procedure

1. label trays for each group, control and experimental group

2. fill each tray with 6 to 7 cm of soil

3. add six lima bean seeds to each of the trays and label them 1-6

4. add 50 mL of water to each tray evenly

5. leave them in sunlight for a week

6. Measure each of the sprouts in each tray

7. Record data and average the heights for each group, control and experimental, as well as find the difference

8. add worms to the experimental group

9. after three weeks measure each of the plants, record the data, average the height, and record the difference

10. after five weeks measure each of the plants, record the data, average the height, and record the difference

Part 3: Data

Week 1:

Control

10, 9, 8, 9, 10, 8 avg. 9

Experimental

8, 9, 8, 8, 8, 7 avg. 8

Week 3:

Control

22, 23, 21, 22, 22, 23 avg. 22

Experimental

24, 28, 26, 25, 27, 26 avg. 26

Week 5:

Control

49, 47, 49, 50, 47, 52 avg. 49

Experimental

50, 60, 49, 53, 58, 60 avg. 55

Part 4: Analysis and Conclusion

Analysis: discuss the relationship between the independent independent variable, explain trends in the data, describe data points to explain the experiment outcome, interpret statistics, and interpret graphs

Conclusion: determine whether the hypothesis was supported, restate the hypothesis, state whether it is correct or incorrect, and explain.

1. What caused the Lake Missoula

klasskru [66]

Answer:

The lake was the result of an ice dam on the Clark Fork caused by the southern encroachment of a finger of the Cordilleran Ice Sheet into the Idaho Panhandle. It was the largest ice-dammed lake known to have occurred.

Name the process by which mucin leaves the goblet cells

ankoles [38]

Answer:

The "Apocrine method" is a process in which the mucin leaves the globet cells.

Explanation:

Globet cells are of columnar globet shaped just like those epithelial cell which is responsible for the secretion of gel forming mucin. For secretion the method used is the merocrine method and for leaving the secretion apocrine method is used. This happens under the stress condition. The apocrine method happens or leaves the secretion through the plasma membrane which produces extracellular membrane bound vesicles. The apical portion of the secretory cells gets pinched and enters into the lumen.

fenix001 [56]

Answer:

A) nutrient A only

Explanation:

In this case, enzyme A is required for the digestion of nutrient A, thereby evidencing that the mutation affects the enzymatic pathway and the mutant strain only can grow by supplementation with this nutrient. In molecular biology, mutant strains are useful to study enzymatic functions (for instance, the role of enzyme A in nutrient assimilation), as well as to examine downstream signaling pathways.

In experimental design, spontaneous mutations are induced to study their effects on the phenotype. Subsequently, reverse mutations may also be induced to reverse the forward mutation, thus restoring the original wild-type phenotype.

What is the process in which the number of chromosomes per cell is cut in half through the separation of homologous chromosomes

Tcecarenko [31]

Answer: Meiosis is a process in which the number of chromosomes per cell is cut in half through the separation of homologous chromosomes in a diploid cell. Meiosis usually involves two distinct divisions, called meiosis I and meiosis II. By the end of meiosis II, the diploid cell becomes four haploid cells.
