Explanation:
Answer:
1) Recursive definition: 
2) At the beginning of the 4th interval
Explanation:
1)
The initial population of the bacteria at time zero is
Here we are told that the reading is taken every two hours; we call this time interval "n", so
And also, after every time interval n, the number of bacteria has tripled.
This means that when n = 1,
And when n=2,
Applied recursively, we get
And substituting p0,
(1)
2)
Here we want to find at the beginning of which interval there are
bacteria.
This means that we can rewrite eq.(1) as
By simplifying,
Which means that
However, this means that the number of bacteria is 1,350,000 after 3 time intervals; therefore, at the beginning of the 4th interval.
Answer:
A = 1
B = 4
C = 5
D = 3
E = 2
F = 6
Explanation:
A) Peptide hormones are not lipid soluble hence known as lipophobic and cannot diffuse through cell membranes examples of peptide hormones include luteinizing hormones, thyroid stimulating hormones, insulin and follicle-stimulating hormones.
B) Steroid hormones can not stored in secretory vesicles because of their lipophilic nature.
C) Amino acid-derived hormone are the hormones which are derived from tyrosine and tryptophan.
D) Anterior pituitary lobe of Pituitary gland is true endocrine gland of epithelial origin.
E) Hypothalamus produce screates six hormones in which vasopressin is also synthesized.
F) Posterior pituitary is responsible for storage and release site for oxytocin
Choices 1, 2, and 3 all emit carbon dioxide, not enough to destroy the planet, but they still can cause it over a large amount of time, due to Carbon Dioxide being a greenhouse gas. Therefore, the answer is 4. Bicycles do NOT emit any carbon dioxide at all.
