Mr. and Mrs. Green have a daughter, Georgia, who was born at Riverside Community Hospital. Mr. and Mrs. Blue have a daughter, Be
Pani-rosa [81]

Answer:

Yes, Mrs Green is correct that Belle is her biological daughter

Explanation:

According to this question, Mr. and Mrs. Green is said to have a daughter, Georgia while Mr. and Mrs. Blue is said to have a daughter, Belle. Both daughters were born the same day. Hence, a controversy occured as Mrs. Green thinks that Belle is her biological daughter.

Based on the blood analysis, the following were obtained:

Mr. Green: Type A

Mrs. Green: Type A

Georgia: Type A

Mr. Blue: Type AB

Mrs. Blue: Type A

Belle: Type O

The genotype of the following blood types is as follows:

Type A - iAiA or iAi

Type B - iBiB or iBi

Type O - ii

Type AB - iAiB

From the analysis of blood types of Mr and Mrs Green, which are both type A, they can possibly produce a child with type A.

However, from the analysis of Mr. and Mrs. Blue, it is impossible to have a child with blood type O. However it is possible for Mr and Mrs. Green if they are both heterozygous (iAi × iAi). The punnet square is attached. Hence, Mrs Green is correct about her claim since Mr. and Mrs. Blue cannot have a child with blood type A.

Explain why glucose consumption must increase in hypoxic tissues to provide the same amount of ATP that could be produced from g
slega [8]

Answer: B. In hypoxic tissues, in contrast to normoxic tissues, ATP is additionally consumed to transform lactate to pyruvate

Explanation:

In hypoxic tissues such as new cancerous cells, the vascular system is still underdeveloped, thus oxygen supply is reduced. To meet energy need, additional glucose is needed to convert lactate (result of anaerobic glycolysis) to pyruvate which can then go into the TCA cycle to yield energy. This phenomenon is very common in muscle tissues during exercise.

(hi, i dont know about this one personally, but i found an answer somewhere else on the internet thatll hopefully help u)

Answer: They consist of long chains of C, H, and O.

Explanation:

In terms of chemical composition, lipids differ from nucleic acids and proteins because they mostly just contain carbon, hydrogen, and oxygen (except for phospholipids which of course contain phosphorous). In addition to those elements, proteins contain nitrogen and sulfur, and nucleic acids contain nitrogen and phosphorous.

Carbohydrates share the C, H, and O composition as lipids, but they differ in structure. Lipids are generally exist as triglycerides, which consist of a triple hydroxyl alcohol (glycerol) that has bonded to three long-chain carboxylic acids (fatty acids) in a triple condensation reaction. Carbohydrates on the other hand are made of carbon ring structures that either remain alone or polymerize into long polysaccharide chains.
