Match the vocabulary term to the correct definition. 1. the complete set of hereditary instructions contained in the DNA chromos

tresset_1 [31]

Answer:

The complete DNA instruction book, or genome, for a human contains about 3 billion bases and about 20,000 genes on 23 pairs of chromosomes
Because carbon atoms can form stable bonds with four other atoms, they are uniquely suited for the construction of complex molecules. These complex molecules are typically made up of chains and rings that contain hydrogen, oxygen, and nitrogen atoms, as well as carbon atoms.
In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
The gene is the basic physical and functional unit of heredity. It consists of a specific sequence of nucleotides at a given position on a given chromosome that codes for a specific protein (or, in some cases, an RNA molecule).

Which of the following statements is TRUE?

Pavlova-9 [17]

Answer:

В. It is possible that your body weight is within the appropriate range, but your body composition is not.

Explanation:

The "BMI" or "Body Mass Index" is used in order to know whether the weight of a person is within the normal range. However, it's not a real indicator for a person's body fat composition in the body.

For example, a person within the normal weight may look healthy because his BMI is within the standard range; however, he may actually be fatty on the inside if his body composition will be checked. Another example are the weightlifters. They may seem heavy on the outside and their BMI are above the normal range; however, their body fat composition is low. So, this means they're healthier though they're overweight.
