Answer:
<u>G. Nitrogenous base</u>
Explanation:
Double-stranded DNA (Deoxyribonuclease) molecules store genetic information. Their 5-carbon deoxyribose sugar, phosphate and one of four nitrogenous bases from which nucleotides derive their name:
The nucleotides on a single strand are bonded together via covalent bonding. Base pairs are formed between nucleotides on opposite strands, due to hydrogen bonding between bases. For instance, <u>Adenine forms double bonds with thymine, while cytosine forms triple bonds with guanine.</u>
Answer:
The girls with polydactyly color-blind and is 1/8, the boys with normal fingers and color vision is 1/8.
Explanation:
X - linked recessive trait may be defined as the trait that are normally passes down from mother to son. Males have high chances since they have only one X chromosme. The female should have both X chromosome affected to express the trait. Autosomal dominant trait express the trait in both the homozygous dominant and heterozygous condition.
The red - green color blinded male with polydactylous is married with female that have normal color vision and normal toes and finger. With the help of pedigree chart and probability,the outcome of their children with specific phenotype can be calculated.
Martha is normal for poldactyly and contains recessive trait for polydactyly. She is a carrier for the color blindness as his father is affected by the disease. Bill is affected by the color blindness and heterozygous for the polydactyly trait. The marriage between marry and bill have the children with 1/8 proportion of the girls can be color bind and shows polydactyly {1/4 ( girls with color blindness) × 1/2 ( the probability of polydactyly}. 1/8 proportion of the boys with normal vision and normal toes and finger {1/4 (boys are normal) × 1/2 ( the probability of normal toes and finger}.
Decomposers break down dead organisms and other organic wastes and release inorganic molecules back to the environment. Food chains and food webs are diagrams that represent feeding relationships. They model how energy and matter move through ecosystems
The best diet would be beef, a glass of skim milk, 3/4 cup strawberries, and 1/2 cup lima beans. Strawberries are a good source of vitamin C while beef, skim milk, and lima beans are good sources of protein.
