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.

Tides on Earth are influenced by
both the moon and the sun
the sun only
the moon only
neither the moon nor the sun
Answer:
The moon only
Explanation:
The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. These bulges of water are high tides.

Characteristics demonstrate that sea anemones are animals and not plants are;
The cells do not contain a membrane-bound nucleus; that is, they are prokaryotic.The organism consists of cells that perform chemosynthesis.What are sea anemones?. They are soft-bodied, sedentary colourful flower-like animals. They are attached to the sea bed with the help of a fleshy foot.
.Thus, the move of sea anemones is restricted. They are good predators and catch prey with their tentacles. Sea anemones possess features of animals thus, cell wall is absent in their cells

Which statement describes a difference between the nitrogen and carbon cycles?
The nitrogen cycle occurs entirely in the ocean.
The nitrogen cycle requires a process called nitrogen fixation that is carried out by certain bacteria.
The carbon cycle requires freezing temperatures.
The carbon cycle involves only plants.
Answer:
The nitrogen cycle requires a process called nitrogen fixation that is carried out by certain bacteria
The primary distinction between the carbon and nitrogen cycles is that the former involves recycling carbon, whilst the latter involves recycling nitrogen. There are numerous ways for both systems to recycle carbon and nitrogen. With gases, both cycles begin and end. Thus, option B is correct.
What between the nitrogen and carbon cycles?Both go through chemical changes that change the shape of the molecules they are contained in. All organisms that are living contain both nitrogen and carbon. Both entail releasing the element into the atmosphere in a molecular form. The cycles start and end as gases.
Therefore, The amount of nitrogen that can be absorbed into organic matter and then recycled rises as the flux of carbon does.Both involve releasing the element as a molecule form into the atmosphere. As gases, the cycles begin and finish.

Why is the elimination of feaces not an excretory process?
Answer:
Feaces is a product of egestion. It is not directly formed from the major organs responsible for excretion (liver, kidneys, lungs and skin) and hence is not a result of metabolic reactions. That is why, feaces are not an excretory product.

1. How many years does the table include, from the first species to the last?
2. From the fossil evidence shown, how did the forefeet change over time?
3. From the fossil evidence shown, how did the skills change over time?
4. How might the environment in which each of these species lived have affected the evolution of horses?
Answer:
1: 50 million years
2: The forefeet changed over time by the bones merging into one to create the hoofed feet that we are used to today.
3: Their teeth and skull changed over time to better fit the environment and food they fed on. Their feet and hight changed based on the physical requirements of the environment like walking across dense forests vs open prairies and how they had to move to access food.
4: The environment affected the way the horses evolved because they had to evolve to better fit and survive/thrive the new environments they lived in.

Explanation:
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).

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
