What is an ionic compound?
Answer:
Ionic compounds are ion compounds. These ions are atoms that gain or lose electrons, resulting in a net positive or negative charge. Metals tend to lose electrons, so they have a net positive charge and become cations. Non-metals tend to gain electrons, creating a net negative charge of anions.

Use your knowledge of the mechanism of photosynthesis and the data presented in the chart to determine which of the statements is a correct explanation for the students' data.Group of answer choicesCup 2 had the highest rate of photosynthesis because it had the highest ratio of disks floating to wattage of light.Cup 1 had a low rate of photosynthesis because 0.5 grams of baking soda did not provide a sufficient amount of CO2.Cup 3 had the same rate of photosynthesis as Cup 1 because they had the same ratio of disks floating to wattage of light.Cup 4 had the lowest rate of photosynthesis because it had the least CO2.
Answer:
D. Cup 4 had the lowest rate of photosynthesis because it had the least CO2.
Explanation:
Carbondioxide gas is the main reactant for the process of photosynthesis which decides the production of food in the leaves. If plants has high amount of carbondioxide gas and water so in the presence of sunlight it produces more food in the leaves in the form of glucose so we can conclude that the lowest rate of photosynthesis occurs due to presence of least concentration of carbondioxide gas in the cup 4.

B. Air and water are equal dense
C. Rain Water is less dense than fog
D. Orange Juice is denser than a whole orange
Answer:
A.
Explanation:
because solid metals will sink when placed on top of whole milk.
Metal is denser than milk is the property of density, these are true. Thus option A is correct.
What is density ?The density can be defined as its mass per volume and it is the ratio between mass and volume, where how much stuff of an object has in a unit volume.
Density is a calculation of matter, where it shows how tightly matter is mixed together, density was discovered by the Greek scientist Archimedes
The density of an object can be represented as the mass (m) can be divided by the volume (v)
Density = Mass/Volume
The SI unit of density is represented as kilogram per cubic meter (kg/m3) or in cgs unit it can be represented as grams per cubic centimeter (g/cm3).
Thus option A is correct.

describe how the intestines, liver, stomach, and pancreas all work together.
Answer:
They work together in the digestive system to make the food originate from the esophagus to the anus.
Explanation:
Answer:
Glands in your stomach lining make stomach acid and enzymes that break down food. Muscles of your stomach mix the food with these digestive juices. Your pancreas makes a digestive juice that has enzymes that break down carbohydrates, fats, and proteins, along with your liver that makes a digestive juice called bile, which helps digest fats and some vitamins. The pancreas delivers the digestive juice to the small intestine through small tubes called ducts. Bacteria in your small intestine make some of the enzymes you need to digest carbohydrates. It also absorbs water with other nutrients. Bacteria in your large intestine help break down remaining nutrients and make vitamin K NIH external link. Waste products of digestion, including parts of food that are still too large, become stool.
Some extra info:
Stomach. Glands in your stomach lining make stomach acid and enzymes that break down food. Muscles of your stomach mix the food with these digestive juices.
Pancreas. Your pancreas makes a digestive juice that has enzymes that break down carbohydrates, fats, and proteins. The pancreas delivers the digestive juice to the small intestine through small tubes called ducts.
Liver. Your liver makes a digestive juice called bile that helps digest fats and some vitamins. Bile ducts carry bile from your liver to your gallbladder for storage, or to the small intestine for use.
Small intestine. Your small intestine makes digestive juice, which mixes with bile and pancreatic juice to complete the breakdown of proteins, carbohydrates, and fats. Bacteria in your small intestine make some of the enzymes you need to digest carbohydrates. Your small intestine moves water from your bloodstream into your GI tract to help break down food. Your small intestine also absorbs water with other nutrients.
Large intestine. In your large intestine, more water moves from your GI tract into your bloodstream. Bacteria in your large intestine help break down remaining nutrients and make vitamin K NIH external link. Waste products of digestion, including parts of food that are still too large, become stool.

In a population of cats, a gene that controls an observable trait has several different alleles. Which of the following best explains how genetic drift might affect the genetic makeup of this cat population over time?
It is a directed process, so it might cause an increase in the gene pool's allele frequencies.
It is a nonselective process, so it might cause an allele to disappear from the gene pool by chance.
It is a random process, so it might cause a population to reach genetic equilibrium.
It is a selective process, so it might cause an increase in the population's genetic variation.
Answer:
It is a nonselective process so it might cause an allele to disappear from the gene pool by chance.

A. Warbler finches and cactus finches are the most closely related.
B. Tree finches and warbler finches are the least closely related.
C. No finches have a common ancestor.
D. Tree finches and cactus finches have a common ancestor.
The phylogenetic tree shown shows tree finches and cactus finches have a common ancestor. So, the correct option is D.
What is Phylogenetic tree?A branching diagram that depicts the evolutionary relationships between a set of creatures, species, or genes is called a phylogenetic tree, sometimes referred to as an evolutionary tree. On the basis of the similarities and contrasts in their physical or genetic traits, it depicts the evolutionary history of these groups.
We can draw the conclusion that cactus and tree finches are more closely connected to one another than they are to any other finch species on the tree. The diagram does not indicate if tree finches and warbler finches are more or less closely related to one another, or whether cactus finches and warbler finches are.
Therefore, the correct option is D.

La respuesta correcta para esta pregunta abierta es la siguiente.
A pesar de que se te olvidó incluir las opciones o incisos para responder a tu pregunta, podemos comentar lo siguiente, basándonos en nuestro conocimiento sobre la materia.
Podemos pensar que la hormona que no produce este niño que sufre de gigantismo es la hormona llamada somatotropina. Esta hormona es muy importante durante el crecimiento y desarrollo del niño en la infancia porque secreta la adenohipófisis, una glándula vital para el correcto y proporcionado desarrollo en la etapa de la niñez.
Entonces, si no hay una secreción correcta de la hormona somatotropina, ésta hace que el niño desarrolle la condición llamada gigantismo.
Entonces podríamos decir lo siguiente.

What is the genetic relationship between individuals Level 1 - 2 and Level
III - 4
Answer:
Grandmother - grandson.
Explanation:
The genetic relationship between individuals Level 1 - 2 and Level III - 4 is grandmother - grandson because the gap between individuals is two generations. The circular shape represents male while on the other hand, the square shape represents female individual. So we know that in the first level, the second individual is square which means it is a female while on the other hand, in the third level, the fourth individual is circular that represents male so it is a relationship of grandmother - grandson.
