D. Phytoplankton are most efficient
Calculate the acceleration of a boat that has been cruising
at 15 m/s but speeds up to 45 m/s in about 6 seconds. Don’t forget your units, m/s2.
In order to calculate the acceleration of the boat we first
have to identify the suited formula for acceleration in this scenario.
Hence, a = vf – vi / t.
Vi = 15 m/s
Vf = 45 m/s
T = 6 seconds
Solution:
A = 45 m/s – 15m/s / 6s
A = 5m/s^2
Answer:
B. DR, Dr, Rd, dr
Explanation:
This question involves two genes. Alleles D and R are dominant over alleles d and r. These two genes obey the law of independent assortment as proposed by Gregor Mendel.
Based on the question, a genotype RrDd will produce the following combination of gametes following the process of meiosis:
DR, Dr, dR, dr
Answer:
Species interaction- competition, predation, parasitism, mutualism, and commensalism.
From the 118 known elements, 25 elements are believed to be essential to human biology.
Out of 25 elements , 6 elements namely – carbon, oxygen, hydrogen, nitrogen, calcium and phosphorus , they make up about 99% of the human body. Some other elements like - potassium, sulfur, sodium, chlorine, and magnesium, they are also found in the human biology.
