Answer: True
Explanation: The U.S. population is projected to increase from 312.2 million in 2010 to 400.9 million in 2050.33 For this four-decade period, that is an increase of 28% at an average annual rate of 0.6%. The anticipated annual rate of growth in the U.S. population is significantly slower than in the past. In the six decades from 1950 to 2010, the U.S. population had increased from 157.8 million to 312.2 million, a total gain of 98% at an average annual rate of 1.1%. Thus, the projected annual rate of growth in the U.S. population is only about half the rate of growth experienced in the recent past. The projected slowdown in population growth is even sharper in the world overall. From 1950 to 2010, the world population increased from 2.5 billion to 6.9 billion, or by 174%. The average annual rate of growth—1.7%—was much higher than in the U.S. In the future, the global population is expected to increase from 6.9 billion in 2010 to 9.6 billion in 2050, or by 38%. The average annual rate of growth—0.8%—is only slightly higher than the rate projected for the U.S.

The correct answer is actually
B) energy that flows from warmer objects to cooler objects.
because temperature is a measure of the average amount of energy possessed by an object due to the random motions of its particles. Heat is the energy that flows from warmer objects to cooler objects. Heat cannot flow in the opposite direction.
<u>Answer</u>: B.The heliocentric model shows that Earth revolves around the Sun. The geocentric model shows that the Sun revolves around Earth.
The geocentric model is also known as the Ptolemaic model and had as center of the Universe Earth. However, the heliocentric model presented by Nicolaus Copernicus and Galileo Galilei, had the sun as the center of the Solar System, with Earth orbiting around it. However, it is thought that this theory was older than Copernicus.
Answer:
48 amino acids
Explanation:
The wild type gene codes for a protein with 100 amino acids. One amino acid is encoded by one triplet code of the gene. This means that the wild type gene has a total 100 triplets or 300 nucleotides to code for a protein of 100 amino acid. Mutation in this protein has introduced the code "UAA" at the 49th codon. The code "UAA" is a stop codon. Therefore, the mRNA transcribed from the mutant allele would code for a protein having 48 amino acids as the protein synthesis will be stopped once the stop codon at the 49th position is read.
Answer:
Which of the following is an advantage of an in vitro experiment?
Variables and environmental conditions are controlled.
Explanation:
An advantage of in-vitro experiment is that the variables and environmental conditions are controlled because in-vitro experiment is performed outside a living organism with the environment in control
