There is a practical joker in the maternity ward who removed all the baby ID bracelets. There are two babies that cannot be easily distinguished, and the parents want to be sure they get the right ones back, so the doctors do a blood test.
Parents 1: mom is heterozygous type A and the dad is type O. Parents 2: mom is heterozygous type A and dad has AB. The baby 1 has blood type AB and baby 2 has blood type O.
Determine what baby goes with which parents. Explain how you know. Provide evidence and reasoning by explaining multiple alleles inheritance and your Punnett squares results.
Answer:
Baby 1 goes to parent 2 and baby 2 goes to parent 1. My results for the first Punnett square for parent 1 was 100% AO. My results for the second Punnett square is 50% AO, 50% OO. My results for the first punnett squares for parent 2 is 50% AA, 50% AB, and the results for the second punnett square is 25% AA, 25% AO, 25% AB, 25% BO.
Explanation:
Baby 1 belongs to parents 2, whereas baby 2 belongs to parents 1.
In this case, it is important to have into account that the ABO blood type is inherited in an autosomal codominant fashion.
The A and alleles B are codominant and therefore both alleles are expressed, thereby if an individual inherits allele A from one parent and allele B from another parent, he/she has blood type AB. It is the case for baby 1 (genotype AB).
Conversely, the A and B alleles are dominant on the allele O, which is recessive. It is the case for baby 2 (genotype OO).
The genotypes of the parents are:
Parents 1:
Mom is heterozygous type A (genotype AO) and the dad is type O (genotype OO).Parents 2:
Mom is heterozygous type A (genotype AO) and dad has AB (genotype AB).Parents 2 can produce these gametes:
Mom: 1/2 A; 1/2 ODad: 1/1 OSo their offspring can be:
A O
O AO OO
F1: 1/2 AO; 1/2 OO
In consequence, baby 2 (genotype OO) belongs to parents 1
Parents 2 can produce these gametes:
Mom: 1/2 A; 1/2 ODad: 1/2 A; 1/2 BSo their offspring can be:
A O
A AA AO
B AB BO
F1: 1/4 AA; 1/4 AO; 1/4 AB; 1/4 BO
In consequence, baby 1 (genotype AB) belongs to parents 2
In conclusion, baby 1 belongs to parents 2, whereas baby 2 belongs to parents 1.

what type of mutation has the least amount of impact on a protein ?
Answer: Silent Mutation
Explanation: Silent mutation: Some mutations that change DNA bases do not have any effect on the sequence of amino acids in the protein. These mutations are called silent mutations and they do not affect the structure or function of the protein because there is no effect on the amino acid sequence.
Answer:
Point Mutations

3. How does your body ensure that the new cells are the same?
Answer:
When cells split and increase they do this very important thing in order tonmake the new cells exactly the same as the previous before them. Each cell makes more of all it's genes. Then each one.splits into two with one group of genes in each one of the new cells. During the process they make sure that all are copied correctly.

describe the effects that fire in the temperate grasslands biome has on grasses and on trees
Answer:
When fire is suppressed, the vegetation eventually converts to scrub and dense forests. Often, the restoration or management of temperate grasslands requires the use of controlled burns to suppress the growth of trees and maintain the grasses. Burning causes new grass to grow, which brings back the grazing animals.

What do you think the term gene expression means? How do you think the term relates to the total number of genes a human inherits from his or her parents?
Answer: Gene expression is how genes are expressed in an organism. This relates to the total number of genes from each parent because the number of genes from each parent determines how your genes are expressed physically.

what are the four molecules that carry energy through photosynthesis
Answer:
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
ATP
ADP
CO2
SUGAR
What is Photosynthesis ?
Plants and other living things employ a process called photosynthesis to transform light energy into chemical energy that can then be released through cellular respiration to power the organism's activities. Despite the fact that various species undertake photosynthesis in different ways, the process always starts when proteins called reaction centres that contain green chlorophyll absorb energy from light. Unlike bacteria, which have these proteins incorporated in the plasma membrane, plants store these proteins in organelles called chloroplasts, which are most prevalent in leaf cells.
When the cell needs energy, ATP can be taken out and used to fuel processes or stored for use in later ones. Animals use ATP to retain the energy released during meal digestion. Similar to this, plants use ATP molecules to store the energy they obtain from light during photosynthesis.
In addition to converting ADP to ATP, photosynthetic processes are used by plants to absorb, process, and store solar energy. Animals convert ADP to ATP, which can subsequently be utilised to drive essential development and cell maintenance, using the energy supplied from the breakdown of glucose and other molecules.
Plants absorb water (H2O) and carbon dioxide (CO2) from the soil and atmosphere during photosynthesis. Water is oxidised, which means it loses electrons, while carbon dioxide is reduced, which means it receives electrons, inside the plant cell. Water is converted into oxygen and carbon dioxide into glucose as a result.

Many people who own pet fish put a pondweed called Elodea canadensis in their
fish tanks. This species of pondweed produces an extremely high amount of oxygen.
If many fish were placed in a tank without this species of pondweed or a filter, what
would likely happen?
Answer:
In the scenario given above, Elodea Canadensis which produces extremely high amount of oxygen is used in raising fishes placed in a tank. This oxygen is needed for easier living in the tank. In a situation whereby the Elondea Canadensis is not present in the tank, the fish would struggle to leave comfortably in the tank. with time, the water will become clouded with carbon-dioxide. This would lead to the fish dying due to lack of oxygen.
