The answer is A because the heart pumps blood from the heart through pulmonary artery that is low in oxygen and high in carbon dioxide concentration, to the lungs.
Answer: I would say A
Explanation: The daughter cell is part of a haploid cell, and for the fertilization process the daughter cell cannot productively function independently, It isn't connected to the parent cell, or at least not for long if i'm incorrect, and every cell contains DNA.
Sugar-phosphates and nucleotides
Answer:
Rigid Structure i think...
Explanation:
Plant cells contain a cell wall which contributes to the <u>rigid</u> structure it obtains.
Answer:
(a) number of strands (n) = time (t) ÷ proportionality constant (k)
(b) The time needed for the bacterial to double its initial size is 3.36 hours.
Explanation:
(a) Let the rate (time) be represented by t and the amount (number) of strands of bacteria be represented by n
t is proportional to n, therefore, t = kn (k is the proportionality constant)
Since t = kn, then, n = t/k
(b) Initial amount of strands = 300
Amount of strands after 2 hours = 300 + (300 × 20/100) = 300 + 60 = 360
k = t/n = 2/360 = 0.0056 hour/strand
Double of the initial size is 600 (300×2 = 600)
Time (t) needed for the bacterial to double its initial size = kn = 0.0056×600 = 3.36 hours
