Answer: in chart 2, the age 65+ line is increasing and the age <5 line is decreasing. These trends indicate that the number of old people is increasing while the number of young people is decreasing.this can strain resources, because there may not be enough young people to take care of the old when they are sick.

Las plantas transforman la luz del sol a través de unas células llamadas: a) Estomas. b) Cloroplastos. c) Raíces. d)Clorofila.
Respuesta:
La respuesta correcta es: b) Cloroplastos.
Explicación:
Los cloroplastos son organelas que se encuentran en las células vegetales y son responsables de realizar el proceso clave para la supervivencia de estos seres vivos: la fotosíntesis.
La fotosíntesis consiste en la transformación de sustancias inorgánicas a materia orgánica gracias a la energía proveniente de la luz solar. Esta materia orgánica será utilizada para la producción de los nutrientes requeridos por las células de la planta.
Los cloroplastos constan de una envoltura conformada por dos membranas y por unas vesículas llamadas tilacoides donde se encuentran las moléculas que participan en la transformación de energía lumínica a energía química que ocurre durante la fotosíntesis, por ejemplo la clorofila (que es un pigmento verde que le da a la planta su característico color).

B. Mechanical Weathering
C. Sediment Deposition
D. Karst Topography
Answer:
I think it's D. Karst Topography

What might happen if a coral species that is well adapted to higher temperature was introduced into a coral reef habitat?
Answer:
May die eventually
Explanation:
A coral species which is living in a regions of high temperature will not be able to be in symbiotic relationship with algae at normal temperature of the sea side coral reefs and may expel it out. A long lasting exposure to change in temperature will lead to bleaching, turning corals white and ma eventually cause death.

Western and Eastern meadowlarks look very similar and it is difficult to tell them apart, until they sing. Their mating songs are quite different. The Western meadowlark has a melodious song, whereas the song of the Eastern meadowlark sounds more like a whistle. Even though their ranges overlap in the central United States, they do not interbreed and are considered two different species. How would speciation MOST LIKELY have occurred in these two species of meadowlarks
Answer:
The correct answer is - Reproductive isolation occurred through behavioral isolation.
Explanation:
Behavioral isolation is a type of isolation that takes place due to the beginning to develop different behaviors in populations of the same species which is not preferred by these different populations.
Due to this behavioral isolation, these populations show reproductive isolation and new species form. The most common example of behavioral differences is mating calls.

What is the role of DNA polymerase in DNA Replication?
reads one strand of DNA and creates another strand
unwind and unzip the DNA
repair errors
bind sugars to phosphates in the backbone
Answer:
One of the key molecules in DNA replication is the enzyme DNA polymerase. DNA polymerases are responsible for synthesizing DNA: they add nucleotides one by one to the growing DNA chain, incorporating only those that are complementary to the template.

What is the measured output force of a pulley system if the Mechanical Advantage is 0.48 and measured input force is 10N?
Answer:
Output force is 4.8 N
Explanation:
A pulley is a simple machine made of a grooved wheel with a rope or cable wrapped around it. Pulleys are used in the transmission of energy or motion.
The input force is also known as the applied force while the output force is the force exerted on an object by a simple machine.
The mechanical advantage of a pulley is the ratio of the output force to the input force.
Mechanical advantage = output force / input force
Substituting:
0.48 = output force / 10
Output force = 4.8 N

Los organismos sencillos como las bacterias, los protozoos, las algas y los hongos no tienen sistema especializado para la excreción, la excreción se efectúa por difusión y transporte activo a través de
Answer:
Por difusión.
Explicación:
Los organismos simples como las bacterias, los protozoos, las algas y los hongos no tienen un sistema de excreción especializado. Hicieron la excreción a través del proceso de difusión en el que los materiales se mueven de la región de alta concentración a la región de menor concentración. Debido a esta difusión, hay una gran cantidad de material de agua presente, por lo que el material de desecho se mueve desde el interior del cuerpo al entorno exterior a través de la membrana presente alrededor de su cuerpo y este proceso de difusión también se utiliza para la absorción de nutrientes.
One parent has type A blood and the other has type B. What are their genotypes if they produced children whose blood types were all type AB?
Answer:
iAiA and iBiB
Explanation:
Blood type in humans is controlled by a gene with three alleles namely: iA, iB, and i. Alleles iA and iB are dominant over allele 'i' but codominant. The following are the allelic combinations of the genotype and the resulting blood types:
iAiA or iAi - type A
iBiB or iBi - type B
iAiB - type AB
ii - type O
According to this question, one parent has type A blood and the other has type B. If all the offsprings of these parents have blood type AB, this means that the parents must have a genotype of iAiA and iBiB respectively.

Answer:
⭕ AirHOPE IT helps!
Answer:
Air
Explanation:
Air is a mixture of various different gases such as nitrogen, oxygen, carbon dioxide etc.

plz help with my hmwk
This process is based on a chemical reaction that occurs when the warm exhaust gases from the coal-fired boiler come into contact with limestone.
When the warm gas comes into contact with the limestone slurry a chemical reaction occurs between the Sulphur Dioxide (SO2) in the gas and the limestone.
This reaction removes the SO2 from the flue gases and converts the limestone into Calcium Sulphite.

4. Ocean currents and waves sometimes deposit sand and dirt offshore, building up a new landform called a(n) Barrier island. Estuary. Marsh. Sea wall.
Answer:
Barrier island
Explanation:
Barrier islands represent a class of coastal landform composed of sand and sediments that forms parallel to the coast. These islands are constantly changing, being shaped by different factors which include water currents (ocean currents), erosion and waves. Some of the most important parameters that influence the length and width of barriers are tidal range (i.e., the height difference between high tide and low tide), wave energy (i.e., the energy restrained from oceanic waves), the amount of sediment supply and sea-level trends.
Answer:
barrier island
Explanation:
A barrier island is a coastal accident composed of sand and other sediments. It might be narrow, of low height, and parallel to the coasts, but separated from them. In general, barrier islands appear like chains that can be composed of a few or several islands. These chains might extend for many kilometers. Their formation depends on many oceanic factors, which can easily form them and then make them disappear, such as waves, tides, streams, and other physical factors of the ocean. They are significant because they protect the coasts and lands from erosion and the damage caused by the storms. Besides, the barrier islands usually provide habitat for many different species. Their shape is very dynamic. They form, get eroded, change position, change their size, disappear and appear again through time. An estuary is a region where freshwater mixes with seawater. These are unique ecosystems where many different species can live in. A marsh is a depressed area saturated and cover by water, where many aquatic plants grow. A sea wall is a structure that is placed on the coasts and that protects them from erosion, specifically, wave erosion. These structures are not separated from the land.how do you get rid of asbestos
