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.

Explanation:

The amount of the gravitational force doubles

When the mass of an object doubles; The amount of gravitational force between it and another object whose mass stays the same doubles.

According to Newton's law of universal gravitation;

On this note, since the mass of the other object is kept constant; the gravitational force is doubled when the mass of the object is doubled.

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.

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.

Un estudiante presenta una condición especial llamada gigantismo su altura es mucho mayor que la de los compañeros de la misma edad y se descarta que la causa sea un problema heredero podemos suponer que este estudiante tiene insuficiente de la hormona de crecimiento o somatotropina. Esta hormona no ingresa a las células en su mecanismo de accion por ser una derivación de aminoácidos.

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.

Answer:

It is a nonselective process so it might cause an allele to disappear from the gene pool by chance.

Answer:

It is because in winters there in mostly less sunlight as compared to summer and as we all know that plants need sunlight frim photo synthesis so in Winter there is less chance of leaves turting to green

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.

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.

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.

The phylogenetic tree shown shows tree finches and cactus finches have a common ancestor. So, the correct option is D.

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.
