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.

El compuesto SeO y HgO es: * óxido ácido y óxido básico óxido ácido y óxido ácido óxido básico y óxido básico óxido básico y óxido ácido
Answer:
óxido ácido y óxido básico
Explanation:
Los óxidos son compuestos químicos formados por la combinación de un elemento químico con el oxígeno (O). Si el elemento que se combina es un metal, el óxido formado se denomina óxido básico. Por el contrario, si el elemento que se combina es un no metal, el óxido resultante es un óxido ácido.
Se (Selenio) es un elemento no metálico, por lo que su óxido (SeO) es un óxido ácido.
Hg (Mercurio) es un elemento metálico, por lo que su óxido (HgO) es un óxido básico.
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.

Yuki has a bowl of ice. She places the ice in a warm room and watches as it melts into liquid water. Yuki then places the liquid water over a Bunsen burner and heats it until it vaporizes. Explain what happens to the water molecules in Yuki's experiment; from the beginning to the end of the experiment.
Answer:
ice is a solid.When heat is added it turns into a liquid,its a reversible change.As regarding to the water moleculesWhen water is heated, it expands, or increases in volume. When water increases in volume, it becomes less dense. As water cools, it contracts and decreases in volume. When water decreases in volume, it becomes more dense. For samples of water that have the same mass, warmer water is less dense and colder water is more dense.Im not sure if this helps but try it out :)

a

b

c

d

Answer:
c increases genetic diversity
Explanation:
Answer:
C. increases genetic diversity
Explanation:
First, by process of elimination: sexual production doesn't necessarily increase survival rate, it can, but not always. Sexual reproduction involves two parents, so b is wrong. And sexual reproduction doesn't produce identical offspring, because it's mixing the genes from both parents, do d is wrong. That only leaves c, with two parents, the gene pool is always expanding, and with less chance of mutation

Plants take energy
from the sun
and make food, which for plants is
Answer:
Photosynthesis
Explanation:
Plants use a process called photosynthesis to make food. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.
Answer:
[tex]\boxed {\boxed {\sf Glucose}}[/tex]
Explanation:
Plants (plus some bacteria and algae) are autotrophs and undergo a process called photosynthesis.
They obtain light energy from the sun and capture it using a green pigment called chlorophyll, water from the soil is drawn up through the roots with capillary action, and carbon dioxide diffuses into stoma on leaves.
Then, in the chloroplast, these substances are turned into oxygen and glucose. Both of these are used in cellular respiration, which creates energy for the plant to grow and carry out cellular and biological functions. Therefore, glucose is often called "food" for the plant.

How do the trachea, bronchi, bronchioles, and alveoli work together to process the oxygen that you inhale?
Answer:

Which of these statements explains why the plants in Groups E and F died? The high sugar content caused too much water to move into the root cells. The high sugar content caused too much water to move into the root cells. The high sugar content clogged the pores in the cell membranes. The high sugar content clogged the pores in the cell membranes. The high sugar content prevented the plant from capturing energy. The high sugar content prevented the plant from capturing energy. The high sugar content caused too much water to move out of the root cells.
Answer:
The high sugar content caused too much water to move out of the root cells.
Explanation:
Too much causes transpiration to occur, in this case too much water killed the plant.
The statement which explains why the plant in Group E and F died is that the high sugar content caused too much water to move out of the root cells.
What do you mean by High sugar content?
High sugar content in plants may be defined as the amount of carbohydrates (glucose) and their components get accumulated in the different parts of the plants in a high ratio. It also affects the rate of photosynthesis.
High sugar content leads to the loss of water (transpiration) in plants. In this condition, water loss is maximum which results in the scarcity of water in the root cells. And hence the plant died.
Therefore, the statement which explains why the plant in Group E and F died is that the high sugar content caused too much water to move out of the root cells.
