Answer:
Exponential population growth: When resources are unlimited, populations exhibit exponential growth, resulting in a J-shaped curve. When resources are limited, populations exhibit logistic growth. In logistic growth, population expansion decreases as resources become scarce.
Explanation:
May I please see the entire table so I can answer your question.
By definition, an arthropod is an animal that is invertebrate and has an exoskeleton also known as an external skeleton. In addition they have a jointed appendages. Other characteristics include segmented bodies, open circulatory systems and bilateral symmetry. Based on this we can say that from the list given we can select "endoskeleton" "jointed appendages"
Answer:
Stage IV - There is a primary tumor, lymph node involvement and metastases.
Explanation:
Staging is the extent of spread of tumor within the patient.
The American Joint Committee on Cancer (AJCC) divides all cancers into Stages 0 - IV, incorporating into each stage several TNM (tumor/node/metastasis) stages usually with the same prognosis.
Staging is essential in determining the patient prognosis.
The approximate 5-year survival rate for colorectal cancer patients of all stages is 64.4% (In the United States) and survival is inversely related to stage.
Surgery usually provides the only curative option for patients diagnosed with Stage IV colon cancer.
Number of Moles are calculate by using following formula,
Moles = Mass / M.mass --- (1)
M.mass is calculated by adding the atomic masses of all elements present in molecule, Since, MgCl₂ contains one Mg (atomic mass = 24.3 g/mol) and two Cl atoms (atomic mass = 35.45 × 2 = 70.9 g/mol), So,
Molar mass = 24.3 g/mol + 70.9 g/mol
Molar Mass of MgCl₂ = 95.2 g/mol
Now, putting values in eq. 1,
Moles = 310 g ÷ 95.2 g/mol
Moles = 3.256 moles
