We calculate the number of moles of water given its mass by dividing the mass by the molar mass.
n water = (36.04 g) / (18 g/mol)
n water = 2 mols
From the given balanced equation, every 6 moles of water produced will require 7 moles of oxygen.
n oxygen = (2 mols H2O) x (7 moles O2 / 6 moles H2O)
n oxygen = 2.33 mols O2

Explanation:
La ________ es un proceso de unión de ______, llamados también células ______________. a. Reproducción - organismos - diploides. b. Reproducción - moléculas - somáticas c. Fecundación - individuos - progenitores d. Fecundación - gametos - haploide
Respuesta:
La fecundación es un proceso de unión de gametos, llamados también células haploides.
La correcta es la D.
Explicación:
El proceso por el cual es posible la reproducción y la continuación de nuestra especie se llama fecundación. La fecundación se produce cuando el gameto masculino, el espermatozoide, toma contacto con el gameto femenino, el ovocito.
Los gametos son células haploides, lo que significa que tienen 23 cromosomas - a diferencia de las células somáticas, que son diploides y tienen dos juegos de 23 cromosomas (46 en total). Esto es importante para que cuando se fusionen ambos gametos, la suma de los cromosomas sea siempre 46.
La manera en la que los gametos obtienen 23 cromosomas en lugar de 46 es gracias al proceso de meiosis.
Cuando se produce la fecundación, la célula resultante será el cigoto que, a lo largo de aproximadamente 40 semanas se desarrollará en el útero de su madre.

Mendel is considered the Father of Genetics. His famous pea plant experiments helped to formulate several laws in genetics that have
stood the test of time with very little modification. Match each law or term with the correct description/definition.
Answer:
The Principles Of Mendel's Genetics
1.Law of Segregation
2.Law of independent assortment
3.Law of dominance
4.Recessive Allele
5.Co-dominance
6.Incomplete Dominance
Explanation:
The Law of Segregation, often known as Mendel's First Law, stipulates that two alleles for a trait segregate during the production of gametes, resulting in each gamete having just one copy of each allele.
What is an explanation of the concept ?This concept explains why a cross between two animals with dissimilar features, such as flower colour, can occasionally result in an intermediate phenotype in the progeny.
Mendel's Second Law, or the Law of Independent Assortment, states that the inheritance of one feature is not reliant upon the inheritance of another trait. This concept explains why a cross between two animals with dissimilar features can result in offspring that exhibits every feasible combination of the two qualities.
Mendel's research with pea plants was groundbreaking in thea branch of genetics. His thorough research and tests resulted in the development of two laws that are now the cornerstones of genetics. According to the Law of Segregation, two alleles for a trait separate from one another throughout the development of gametes, leaving just one allele per trait in each gamete.
This concept explains why a cross between two animals with dissimilar features, such as flower colour, can occasionally result in an intermediate phenotype in the progeny.
According to the Law of Independent Assortment, one trait's inheritance is not correlated with that of another. This law explains how a cross between two creatures with distinct features can result in offspring that can display any combination of the traits.

How does your model show what happened to the circled rock material as a result of plate motion?
Answer:
Once exposed, they are weathered, both physically (by mechanical breaking of the rock) and chemically (by weathering of the minerals), and the weathering products — mostly small rock and mineral fragments — are eroded, transported, and then deposited as sediments. Therefore, the model should show signs of deterioration and subduction.

Question: Can Hox genes be transcribed?
Answer:
os genes Hox son un grupo de genes selectores homeóticos, que a su vez conforman un subconjunto de la familia de genes homeobox y son uno de los conjuntos de genes más implicados en el desarrollo embrionario. Los genes Hox actúan en el control maestro del desarrollo del eje anteroposterior de varios organismos multicelulares, que incluyen gran variedad de taxas animales y a la mayoría de los tunicados y, aunque existen otros genes parecidos en plantas, no se ha demostrado homología. Los factores de transcripción expresados por el conjunto de genes Hox, se encargan de la regulación de la morfogénesis y diferenciación celular durante el desarrollo embrionario temprano y, aunque el patrón de expresión conlleva ajustes complejos conforme el desarrollo va progresando, en cada célula el complejo Hox actúa como un sello o marca de registro permanente de la posición anteroposterior que ocupa la célula en el embrión.

In patients infected with nonresistant strains of the tuberculosis bacterium, antibiotics can relieve symptoms in a few weeks. However, it takes much longer to halt the infection, and patients may discontinue treatment while bacteria are still present. How could this result in the evolution of drug-resistant pathogens?
The bacteria are still present and may obtain antibiotic resistance to spread to other species by horizontal gene transfer.
Antibiotics have become diluted and weak because of a limited supply.
Bacteria have purposefully directed their immune system to resist the effect of the antibiotic.
Resistant bacteria are polyploidy and can resist the antibiotic, a trait that is passed on to their offspring.
Answer:
The bacteria are still present and may obtain antibiotic resistance to spread to other species by horizontal gene transfer.

What causes stomach cramps?
Answer:
the main causes are, infection,abdominal growth,inflammation,obstruction blockages
Explanation:
“Stomach cramps” is a general term that refers to sharp, intermittent contractions or feelings of pain or discomfort that occur anywhere in the abdomen between the lower chest and the pelvis or groin. The abdomen consists of many organs, including the stomach, intestines, liver, gallbladder, pancreas, esophagus, and numerous blood vessels.
Stomach cramps are a common symptom of a wide variety of mild to serious diseases, disorders and conditions that are often related to the abdominal organs and sometimes the pelvic organs, such as the uterus and bladder. Most people will experience stomach cramps at some point during their lifetime, and they can occur in any age group or population. Common causes of stomach cramps include indigestion, gastroenteritis, menstrual cramps, bladder infection, and excessive flatulence (gas).
Stomach cramps may be generalized, which means they occur throughout the abdomen. Stomach cramps may also be localized in a small area of the belly, such as the lower abdomen or pelvis near the groin, or in the upper abdomen where the stomach is located.
Depending on the cause, stomach cramps can last for a few minutes or hours, such as when they occur from indigestion due to eating rich food or from vigorous exercise. Stomach cramps can also last for a few days, such as when they are due to a menstrual period. Long-term stomach cramping may be continuous or occur periodically and may be due to more serious conditions, such as colorectal cancer.
In some cases, stomach cramps may be caused by serious conditions, such as food poisoning or colorectal cancer. Seek prompt medical care if your stomach cramps are unexplained, persistent, or cause you concern.
Stomach cramps may accompany other symptoms, which vary depending on the underlying disease, disorder or condition. If you have other symptoms along with stomach cramps, be sure to inform your health care provider. This information will help your doctor diagnose the reason for your stomach cramps.

Gray rabbits would be eliminated by predators.Explanation:
Gray population rabbits would blend into either environment would most likely happen to the gray rabbits. So, the correct option is A.
What is Population?A population is a collection of organisms belonging to the same species that co-exist in the same place and are able to reproduce. Members of a population interact with each other through mating, competition for resources, and other social behaviors. They also share a common gene pool.
The ratio of the birth rate of a population to its death rate as well as immigration and emigration determine the size of the population. When the birth rate exceeds the death rate, population growth results; When the death rate is high, the population declines. Emigration occurs when people leave a population to go elsewhere, whereas immigration occurs when people move into a population from outside.
