The six pedigree symbols with the corresponding names of the individuals in Rose's family will be like 2nd - Rose; 7th - Becky; 4th - Dave; 8th - Mike; 10th - Pat and 13th - Erik.
The second will be Rose because Becky's father, who is Rose's husband, is healthy and Jess, Becky's mother, has myotonic dystrophy. The seventh person is Becky, who has myotonic dystrophy and is married to Mike, who is healthy. Dave, who has myotonic dystrophy, is the fourth.
Mike, who is normal and married to Becky who has the condition or is impacted, comes in at number eight. Pat (unaffected), the daughter of Dave and Mary, is ranked tenth. Erik (affected), the son of Becky and Mike, is the 13th person on the list.
Myotonic dystrophy is an autosomal dominant condition that is passed vertically from parents to offspring. This illness affects both men and women equally and does not pass down through generations.

The answer is true, since catabolism is the breakdown of more complex compounds into more simpler ones.
Answer:
Water along with carbon dioxide and oxygen are the agents of chemical weathering to support that statement.
Explanation:
- Chemical weathering is the continuous process that makes the rocks weak and decompose by changing its composition.
- Water is the main agent for chemical weathering, the molecules of water separates the ions from their existing compounds and edges them.
- Water has the ability to completely dissolve some minerals. for example, salt.
- Oxygen also takes part in chemical weathering by the process called as oxidation.
- Similarly carbon dioxide initiates weathering by the acid rain.
Answer:
Catalyst, in chemistry, any substance that increases the rate of a reaction without itself being consumed. Enzymes are naturally occurring catalysts responsible for many essential biochemical reactions.
Answer:
The classic tool to predict the patterns of heredity is using a <u>Punnett Square</u>.
Explanation:
In genetics, a trait can be considered dominant or recessive. Since the important discoveries of Gregor Mendel, scientists use a <u>capital letter (D) to indicate a trait is dominant, and a lowcase letter (d) to show a trait is recessive. </u>
Assuming that a scientist knows the genotype for the desired trait they want to predict on the offpsring, a Punnett Square is<u> a reliable tool and a graphic representation that permits them to visualize the potential features of the offspring by showing how the alleles may be exhibited and passed on the offspring and will determine the possible combination of genotypes.</u>
<em>How does it work?</em>
For example, as we can observe in the image below, both parents are homozygous for a trait <em>PP=Purple; pp=white</em>. P is dominant and p is recessive (the color purple will be dominant, and the white will be recessive). So, we put one parent's genotype in the top row (PP) and the other parent's genotype in the left column (pp) and combine one of each letters on the squares, <em>i.e</em>. one of each parent's alleles. Then, we can observe in the results that 3 of the offspring will exhibit the purple color (PP, Pp, Pp) and only one will exhibit the white recessive color (pp); or more properly known as a genotypic ratio of 3:1.
