The map shows the allele frequency of sickled hemoglobin (HbS) and malaria endemicity in Africa.
(Picture Below)
Which statement best explains the relationship between HbS allele frequency and malaria endemicity in Africa?
A)When an area is malaria free, the HbS allele frequency is between 0 and 2.02.
B)When an area is holoendemic, the HbS allele frequency is between 0.52 and 4.04.
C)When an area is malaria free, the HbS allele frequency is between 12.64 and 18.18.
D)When an area is holoendemic, the HbS allele frequency is between 0 and 0.51.
Answers
When an area is malaria-free, the HbS allele frequency is between 0 and 2.02. Thus, option "A" is correct.
How, explain your answer briefly?In the two maps that show the allele frequency of sickle haemoglobin (HbS) and malaria endemicity in Africa, it can be seen that in the regions with no malarial outbreak or malaria-free areas coincide with the grey to lighter shades of red in the heat map of the allele frequency of HbS. The colour coding in the heat map for the allele frequency tells us that the frequencies range from 0 to 2.02 in the malaria-free areas.
Hence the answer is A)When an area is malaria-free, the HbS allele frequency is between 0 and 2.02.

Following digestion and absorption into the enterocyte, monoglycerides and free fatty acids are repackaged in what structure? a. Bile Duct
b. Chylomicron c. Sphincter d. Micelle e. Sinusoid
Answers
Following digestion and absorption into the enterocyte, monoglycerides and free fatty acids are repackaged in the structure known as a chylomicron.
Chylomicrons are formed in the endoplasmic reticulum of the enterocyte and then transported into the lymphatic system via the lacteals. The chylomicron is responsible for transporting lipids from the small intestine to various tissues in the body. Once the chylomicron reaches its destination, lipoprotein lipase breaks down the triglycerides into free fatty acids and glycerol, which are then utilized by the cells for energy or stored for later use.
Therefore, chylomicrons play a crucial role in lipid metabolism and transport. Following digestion and absorption into the enterocyte, monoglycerides and free fatty acids are repackaged in the structure known as a chylomicron (option b).

1. Critic the following two views from the perspective of today’s sustainability. (50 points)
• Aristotle’s anthropocentric view: "Plants exist to give food to animals, and animals, to give food to men. … Since nature makes nothing purposeless or in vain, all animals must have been made by nature for the sake of man."
• Biocentric outlook by Paul Maylor: It values all living things in Earth’s community, so each organism is "a center of life pursuing its own good in its own way," and all organisms are interconnected.
Answers
Aristotle's anthropocentric view places humans at the center and considers other organisms as means to human ends, whereas the biocentric outlook recognizes the intrinsic value of all living things and emphasizes the interconnectedness and independent pursuit of well-being by each organism.
Aristotle's anthropocentric view, while reflective of the dominant perspective during his time, is heavily criticized from the perspective of today's sustainability. This view places humans at the center and considers the natural world as existing solely for human benefit. It disregards the intrinsic value and interconnectedness of all living organisms and ecosystems. This anthropocentric mindset has led to unsustainable practices, exploitation of natural resources, and the degradation of ecosystems, resulting in environmental crises such as climate change, habitat loss, and species extinction.
On the other hand, Paul Maylor's biocentric outlook aligns more closely with the principles of sustainability. It recognizes the inherent worth and autonomy of all living beings and acknowledges the interdependence of organisms within Earth's community. This perspective emphasizes the need for ecological balance and harmonious coexistence, promoting a more holistic approach to environmental stewardship.
From the standpoint of sustainability, the biocentric outlook offers a more comprehensive and ecologically responsible framework. It encourages a shift away from exploitative practices towards a greater respect for the intrinsic value of nature and the need for conservation and preservation. By recognizing the interconnectedness of all life forms, this perspective promotes sustainable living that supports the well-being of both humans and the natural world.

Answers
The statement that the duodenum is the longest segment of the small intestine is false.
While the duodenum is the first segment of the small intestine, it is actually the shortest, measuring only about 10 inches in length. The longest segment of the small intestine is actually the ileum, which can measure up to 12 feet long in an adult.
The ileum is responsible for the majority of nutrient absorption, particularly vitamin B12 and bile salts. It also plays a role in the immune system, as it contains Peyer's patches which are important for the development of lymphoid tissue and the production of antibodies.

c) Porcentaje genotípico de los hijos.

El enunciado hace referencia a un caso de herencia monogénica y dominancia completa para el rasgo 'color de ojos', donde el padre es heterocigota y la madre es homo-cigota recesivo.
Las respuestas a estas preguntas son:
a) Genotipo del padre: Aa (ojos negros)
b) Cruzamiento: Aa (padre) x aa (madre)
c) Frecuencias genotípicas esperadas: 1/2 Aa; 1/2 aa
En genética, dominancia completa se refiere al proceso de herencia en la cual un individuo heterocigota, es decir, el individuo que presenta dos alelos diferentes para el mismo gen, presenta el mismo fenotipo que un individuo homo-cigota para el alelo dominante (el alelo dominante es aquel que enmascara la expresión del alelo recesivo en individuos heterocigotas).
En este caso, el carácter 'color de ojos' presenta un patrón de herencia monogénica, donde el alelo 'A' dominante codifica para el rasgo fenotípico ojos negros, mientras que el alelo 'a' recesivo codifica para el rasgo fenotípico ojos azules.
En el ejemplo, la pareja tuvo progenie en la cual uno de los hijos presenta el rasgo recesivo ojos claros, y por lo tanto el padre debe ser heterocigota y poseer un alelo recesivo 'a'; mientras que la madre expresa el fenotipo recesivo y por lo tanto su genotipo es 'aa'. En consecuencia, el cruzamiento de un padre heterozigota 'Aa' con una madre homo-cigota recesivo 'aa' producirá una descendencia con una frecuencia genotípica esperada de 1/2 (50%) de hijos con ojos 'color negro' de genotipo Aa y 1/2 (50%) de hijos con ojos 'color celelste' de genotipo aa >>
Cruzamiento: Aa (padre) x aa (madre)
Gametos padre: 1/2 A; 1/2 a
Gametos madre: 100% a
Cuadro de Punett (combinaciones gaméticas):

En consecuencia, este cruzamiento producirá 50% individuos ojos color negro (genotipo Aa) y 50% individuos con ojos color celelste (genotipo aa)

consider the dna non-template strand: 5’ – cat gag tac – 3’. what is the correct amino acid sequence?
Answers
The correct amino acid sequence for the given DNA non-template strand (5’ – CAT GAG TAC – 3’) is His-Glu-Tyr.
This is because the DNA non-template strand is complementary to the template strand, which is used to create the mRNA sequence. The mRNA sequence is then used to create the amino acid sequence during translation.
Here is a step-by-step explanation:
1. First, find the complementary DNA template strand for the given non-template strand. The complementary base pairs are A-T and C-G. So, the DNA template strand is 3’ – GTA CTC ATG – 5’.
2. Next, transcribe the DNA template strand into mRNA. The base pairs for mRNA are A-U and C-G. So, the mRNA sequence is 5’ – CAU GAG UAC – 3’.
3. Finally, translate the mRNA sequence into the amino acid sequence using the genetic code. The codons (groups of three bases) in the mRNA sequence correspond to specific amino acids. The codons and their corresponding amino acids are:
- CAU = His (Histidine)
- GAG = Glu (Glutamic acid)
- UAC = Tyr (Tyrosine)
So, the correct amino acid sequence is His-Glu-Tyr.
