Answer:
sickle cell anemia and malaria
Explanation:
Scientists believe the sickle cell gene appeared and disappeared in the population several times, but became permanently established after a particularly vicious form of malaria jumped from animals to humans in Asia, the Middle East, and Africa.
The two diseases have been studied together that provide evidence of evolution in humans is sickle cell anemia and malaria.
What is sickle cell mutation?
The sickle cell mutation is relevant to malaria because infection of a red blood cell with the malaria parasite leads to hypoxia. In individuals of the AS genotype such blood cells sickle and are then eliminated by macrophage cells of the body’s immune system, lessening the burden of infection (Luzzatto, 2012). Carriers of the sickle cell trait are particularly resistant to severe malarial episodes; they are less resistant to mild cases. The mechanism by which carriers are protected from malaria is different than the acquired immunity that both AA and AS individuals achieve following repeated exposure to the disease.
The benefit that possessing a single copy of the sickle cell gene conveys counterbalances the biological cost incurred when homozygous SS children are stricken with sickle cell disease. An individual of the AS genotype is more likely to reach adulthood than is an individual of the AA genotype, but the former is also more likely to see his/her child die of sickle cell disease. This is known as a heterozygote advantage or balanced polymorphism. As shown more formally below, the stronger is the pressure of malaria on survival, the more advantaged are individuals who carry the S gene, and in equilibrium, the higher the percentage of the population who will be carriers. Indeed, it was the correlation of high prevalence of the sickle cell gene and the presence of malaria that first led scientists to understand the protective role of the sickle cell mutation (Kwaitkowski, 2005). As will be seen in the next section, the underlying genetic mechanism by which the sickle cell trait is transmitted provides a means of mapping sickle cell prevalence into an estimate of the mortality burden of malaria.

Self-heating cans use the concept of an interior heating vessel that is able to warm up food. The diagram below shows a model of how a self-heating can works.
When the activation button is pressed, the water is released into the calcium oxide. When the water and calcium oxide mix, a chemical reaction occurs and releases heat, which is able to heat the soup in the can. Which statement best describes the interior heating vessel?
A.
It is able to produce a larger quantity of food through the process of a chemical reaction.
B.
It is designed to insulate thermal energy from moving from one medium into another.
C.
It is able to regulate the flow of the calcium oxide and water into the food to make it warm.
D.
It is designed to control when thermal energy is produced and where it can flow.
D. It is designed to control when thermal energy is produced and where it can flow. The interior heating vessel contains the calcium oxide and water separately until the activation button is pressed, which allows them to mix and undergo a chemical reaction that releases heat.
What are Self-heating cans?Self-heating cans are a type of food packaging containing all the necessary components to heat the food within the can without needing an external heat source. These cans are designed for convenience when there is no access to a stove, microwave or other traditional heating sources.
What is the use of self-heating cans?Self-heating cans are often used for ready-to-eat meals, soups, and other similar food products. They are popular for outdoor activities such as camping, hiking, and emergencies where access to heat sources is limited. However, they can be more expensive than traditional canned foods and are not always easily recyclable.

Insertion mutation I believe.
A codon chart can be used to read the genetic code. To utilize this chart, start by finding the first codon nucleotide, then the second, and finally the third. The chart will then show which codon codes for the amino acid. Because the genetic code is degenerate, there are several codons for each amino acid.
What role of genetic code in DNA sequence?The genetic code serves as the body's language for converting the DNA instructions from our genes into the constituent parts of life. It is typically discussed using the “codons” found in mRNA since mRNA is the messenger that transmits information from the DNA to the site of protein production.
Therefore, TAC GGG AGT CTT TCC ACT -DNA

Transformation is a process in which bacteria take up new DNA released by dead cells and integrate it into their own genomes (see Chapter 9). In Streptococcus pneumoniae (which causes many cases of pneumonia, inner-ear infections, and meningitis), the ability to carry out transformation requires from 105 to 124 genes, collectively termed the com regulon. The com regulon is activated in response to a protein called competence-stimulating peptide (CSP), which is produced by the bacteria and exported into the surrounding medium. When enough CSP accumulates, it attaches to a receptor on the bacterial cell membrane, which then activates a regulator protein that stimulates the transcription of genes within the com regulon and sets in motion a series of reactions that ultimately result in transformation. Does the com regulon in S. pneumoniae exhibit positive or negative control
Answer:
Positive (inducible)
Explanation:
Increased levels of CSP induce the receptor to stimulate transcriptional activator functions, which allow gene expression to occur similar to what happens in positive inducible.

The polar regions increase salinity because the water is frozen
The cooler waters decrease the salinity of the water near the equator,
Evaporation rates of warm water increase, which increases the salinity of water
Warmer waters cause evaporation to be slowed down, which decreases salinity of water,
Answer:
Evaporation rates of warm water increase, which increases the salinity of water.
Explanation:
Evaporation rates of warm water increase, which increases the salinity of water because the amount of water is decreases which automatically increases the salinity in water. This higher salinity can be balanced by the continuous falling of fresh water from rivers into the sea ocean. There is higher rate of evaporation in warm water due to intensity of sunlight which cause the change of state from liquid to vapor form of water.

Clasisifcar los huesos del esqueleto apendicular y axial en : largos, cortos, planos, irregulares, sesamoideos. ayudaaa por favor!!
Answer: Se clasifican de acuerdo a la forma y tamaño.
Explanation:
El esqueleto posee distintas funciones como el soporte del cuerpo en sí y la protección de órganos vitales. Para lograr esto, existen distintos tipo de huesos con distintas formas, de acuerdo a su ubicación y función.
Los huesos del esqueleto humano se dividen en dos grandes grupos:
Esqueleto apendicular: Huesos que forman los miembros superiores e inferiores, además de la cintura escapular y la pelviana. El esqueleto axial: Huesos del eje largo del cuerpo en la cabeza, columna y caja torácica.Tanto en el esqueleto apendicular como en el axial, existen cinco tipos de huesos: largos, cortos, planos, irregulares, sesamoideos.
Largos: Se clasifican así por ser mas largos que anchos y su función es la de soportar el peso del cuerpo y producir movimiento. Se ubican principalmente en el esqueleto apendicular como por ejemplo, huesos del miembro inferior como el fémur, tibia y peroné de las piernas. Además de los huesos en los miembros superiores como radio, húmero, cúbito en los brazos; y falanges metacarpianos en las manos.Cortos: Se clasifican así por tener aproximadamente la misma longitud que ancho, y su función es proporcionar estabilidad y movimiento. Estos huesos se ubican en articulaciones del tobillo y muñeca. y algunos ejemplos son los huesos tarsianos en tobillos (navicular, cuboides, astrálago, calcáneo, cuneifrome lateral, intermedio y medial); y los huesos carpianos de la muñeca (piramidal, pisiforme, trapezoide, trapecio, escafoides, hueso ganchoso, hueso semilunar, hueso grande)Planos: Son huesos de forma plana y su tamaño de área grande sirve para la unión de distintos músculos. Su función principal es la de la protección de órganos internos. Entonces, se encuentran en la caja torácica (donde se encuentran por ejemplo las costillas y esternón), y en la pelvis (donde se encuentra el ilion, isquion y pubis). También forman parte de la estructura ósea de la cabeza, donde se hallan los huesos occipital, frontal, parietal, lagrimal, nasal y vómer.Irregulares: Su forma y estructura es variable además de que pueden tener forma compleja. Su función es la de proteger órganos internos, por ejemplo a la médula espinal que es protegida por las vértebras y huesos irregulares de la columna vertebral .Sesamoideos: Huesos redondos en tendones donde los protegen del deterioro, particularmente en los tendones de las manos, pies y rodillas, como por ejemplo la rótula.How many of the hypothetical offspring produced during this lab activity had the same phenotype?
