What two diseases have been studied together that provide evidence of evolution in
humans?
A)malaria and ebola
B)sickle cell anemia and malaria
C)cytochrome c disease and plasmodium fever
D)iron-deficient anemia and yellow fever
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.

Que tedria de particular la retina de un animal que no pudiera diferenciar los colores cuya vision fuera exclusivamente en blanco y negro
Answer:
La falta de células cono en la retina
Explanation:
En vertebrados, la retina se encuentra formada por dos tipos básicos de células denominados células conos y células bastones. Las células cono son unas células fotosensibles las cuales forman una capa concentrada en el centro de la retina. Estas células (células cono) son responsables de la distinción entre diferentes colores del espectro de luz visible. Las células cono se clasifican en tres tipos de acuerdo a su sensibilidad para distinguir la luz azul, roja, y verde. Esta sensibilidad se debe a la presencia de diferentes tipos de proteínas opsinas, las cuales confieren la capacidad de absorber la luz en una longitud de onda particular: cianopsina (sensible a la luz azul), eritropsina (sensible a la luz roja) y cloropsina (sensible a la luz verde). Animales como los gatos y los perros son daltónicos, es decir, no pueden completamente diferenciar los colores, debido a la falta de una o más clases de células cono (y por lo tanto también de opsinas) en la retina.
What is index of refraction and what does it have to do with the speed of light?
Answer:
Index of refraction is the ratio of the velocity of light in medium to the velocity of light in vacuum.
OR:
Index of refraction is the ratio of the sine of the angle of incidence to sine of the angle of refraction of light propagating from one medium to another.
When the refractive index is greater, the speed of light is greater as it moves from the medium to vacuum.

What part of the digestive system first causes chemical changes to food?
A. teeth in the mouth
B. saliva in the mouth
C. enzymes in the stomach
D. enzymes in the small intestine
Answer:
b. saliva in the mouth
Explanation:
saliva contains enzymes that help break down food
Saliva in the mouth causes the first chemical changes in the food. So the correct option is B.
What is saliva?Saliva is a continuously present, viscous, colorless, opalescent fluid in the mouths of humans and other animals. It is made up of amylase, water, mucus, proteins, and mineral salts.
Saliva takes up food particles, bacterial cells, and white blood cells as it moves about in the oral cavity. Every day, a person's mouth excretes one to two liters of fluid.
The total amount of saliva is produced by three primary pairs of salivary glands as well as numerous smaller glands that are dispersed across the has included of the cheeks, lips, tongue, and palate.
The mouth naturally produces small amounts of saliva on a regular basis, but the introduction of food, or even just the scent or idea of it, will significantly enhance saliva production.
Salivation serves a variety of purposes. In order to aid in speaking and transform foodstuffs into a liquid or semisolid material that can be tasted and taken more readily, it primarily lubricates and moistens the interior of the mouth.
Therefore the correct option is B.

What organic molecule contains a carboxyl functional group and an amino functional group?
A. DNA
B. carbohydrate
C. lipid
D. protein
The basic amino group (NH2), the acidic carboxyl group (COOH) and the specific organic R group (or side chain) for each amino acid make up an organic molecule known as an amino acid. Thus, option D is correct.
What is Structure of protein?
The linear arrangement of amino acids within a peptide or protein constitutes its fundamental structure.
Conventionally, a protein's main structure is described from amino-terminal end to carboxyl-terminal end. Ribosomes in cells are most frequently responsible for protein production.
Peptide bonds are created when amino acids condense to form protein structures. The main structure of a protein is its arrangement of amino acids.
The dihedral angles of the peptide bonds determine the secondary structure, while the folding of protein chains in space determines the tertiary structure.
Therefore, a protein organic molecule contains a carboxyl functional group and an amino functional group.

Answer:
The cells on the shaded side of the plant will shrink, causing the opposite side of the plant to grow toward the window.
Explanation:
The cells on the shaded side of the plant will shrink, causing the opposite side of the plant to grow toward the window.
Hydrogen ions are released in the cells on the shaded side of the stem. As a result, the pH of the cells decreases that in turn activates expansins (an enzyme). This enzyme causes the opposite side of the plant to grow toward the window.
Finn listed two of the three steps involved in gene therapy. 1. The normal allele is removed from the chromosome. 2. The normal allele is added to the cells of a person with the disorder. Which step should he also include, and where?
Answer:
The unhealthy gene sequence is cut from the DNA before 2
Explanation:
Gene therapy refers to genetic engineering techniques aimed at introducing exogenous nucleic acids (either DNA or RNA) into the patient's cells in order to restore gene function. Gene therapy techniques hold a great promise to treat genetic diseases and disorders. Gene therapy may involve replacing defective genes with a functional copy of the gene of interest within the desired cells. For this purpose, it is required to use a DNA-specific damaging agent to knock out the defective gene and subsequently restore normal gene function by inserting a functional gene sequence into the recipient cells. Gene therapy techniques can be divided regarding target cells into 1-somatic gene therapy, where genetic modifications are applied on somatic body cells (and therefore they are not inherited by offspring), and 2-germinal gene therapy, where genetic modifications are applied on germinal cells (i.e., gametes) or undifferentiated stem cells (and therefore genetic changes may pass to the following generations).
