Answer:1.) is LAW and 2.) is experiment
Explanation: i already did this
A theory is an accepted explanation of an observed phenomenon supported by empirical data, whereas the scientific method is an organized way of gathering information involving observation and theory to test scientific hypotheses.
1.) A theory is an accepted explanation of an observed phenomenon supported by empirical data. For example, the theory of evolution is an accepted explanation of the observed changes in species over time, based on a wealth of empirical evidence from biology, geology, and other fields. 2.) The scientific method is an organized way of gathering information involving observation and theory to test scientific hypotheses. This process includes making an observation, asking a question, doing research, constructing a hypothesis, testing the hypothesis through experimentation, analyzing data, and drawing a conclusion.

Answer: external fertilization
Explanation:
External fertilization is the process of fertilization in which the male sperm cells fuses with the female egg cells outside the body of the female. This type of fertilization is used by the organisms which live in the water body.
The salmon is a fish species which utilizes external fertilization. In the case of salmon, the female salmon drops the eggs in the bottom of the water which are fertilized by male salmon after secreting their sperms over these eggs.
The possible blood type of offspring, when a woman with type O and a man who is type AB are expecting a child are A and B.
There are four kinds of blood groups which are A, B, AB, and O, based on the presence of antigens in RBC. Blood groups A and B show co-dominance, while O is recessive.
When a woman with type O blood and a man who is Type AB are expecting a child, the possible blood types are A and B. 50% of the children would have A blood type, and 50% of children would have blood type B, which are heterozygous.
When Parents are both heterozygous for the B blood group, then the possible blood group of offspring would be 75% B blood type (25% are homozygous and 50% are heterozygous) and 25% O blood type.

The correct answer is " Both the patients need re-vaccination"
As per the “Center for Disease Control and Prevention (CDC)” it is recommended that all adults of age 60 or above are at high risk of pneumococcal disease. As per their statistics every year thousands of adults die because of pneumococcal diseases.
CDC recommends that two series of vaccines against pneumococcal diseases is sufficient to protect adults against this disease:
• PCV13 (pneumococcal conjugate vaccine)
• PPSV23 (pneumococcal polysaccharide vaccine)
As per CDC all adults with age 65 or above but since the first patient of 66 years of age is diabetic, he must also get re-vaccinated along with the second patient of age 76 years.
