Let's use process of elimination to answer this question!
D is wrong, and we know this because of the names of DNA and RNA. The D in DNA stands for deoxyribose, and the R in RNA stands for ribose. These are the types of sugars in each nucleic acid. Therefore, they don't both contain a ribose sugar.
C is wrong, and this is because RNA does not contain thymine, but uracil instead.
B is wrong, and we know this because we know that RNA is composed of only one strand, and therefore it is not composed of multiple stands (plural).
Therefore, A must be right. We can confirm this, because we know that polymers are large molecules consisting of repeated subunits. DNA and RNA are both polymers consisting of nucleotides.<span />
There is going to be a 25% chance of it being heterozygous unless both parents are heterozygous then if so you do happen to have to heterozygous parents it will be 100% heterozygous.
One type of atom
a pure substance
Explanation:
Because we always seek to make sense of any perceived stimulus to better understand the reality that surrounds us and act before it. Through perception we process information from the senses, with which the brain builds and tries to give meaning to those stimuli that reach it. However, each person captures, selects and organizes sensory stimuli differently and, therefore, arrives at different interpretations and responses when solving a problem, in which memory and experience also form a fundamental role. Thus, differences between perceptions help explain how people interpret the environment and why they behave differently in the same situation. For example, when we recognize a specific object, an action can be initiated, in which a motor activity is propitiated in response to that recognition, and which can be different in each person.
