Answer:
Célula procariota y procariotas.
Explicación:
La célula procariota es un tipo de célula que apareció por primera vez en la Tierra hace unos mil millones de años. Estos tipos de células están presentes en los procariotas, lo que significa que estos organismos no tienen un núcleo verdadero o una membrana nuclear alrededor del núcleo y otros orgánulos de la célula. El ADN del organismo procariótico se encuentra en una parte central de la célula que se conoce como nucleoide. La pared celular de un procariota actúa como una capa adicional de protección, ayuda a mantener la forma y estructura celular y previene la deshidratación.

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.

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.

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

Ferns have vascular tissue, an adaptation to life on land, but they have an ancestral reproductive trait that tends to limit them to moist habitats. What is it?
Answer:
The correct answer is - flagellated sperm.
Explanation:
In ancestral trait that is flagellated sperm in ferns that were limited to moist habitat has sperms that must swim to the eggs. This is why ferns often require splashing water for the movement of sperm to points near female gametangia during reproduction.
Fern now adapted the vascular system to get life on the life and they are not limited to the water bodies, however, flagellated sperm is the ancestral reproductive trait.

Explanation:
The best definition of technology is the practice applications of the scientific knowledge. The correct option is D.
What is Technology?Technology involves the practical use of scientific knowledge to create tools, machines, and systems that improve our lives and solve problems. It is not limited to just electronic devices, but encompasses a wide range of fields including engineering, medicine, and agriculture.
Technology is the means through which we put scientific knowledge to use. It encompasses both tools (like computers) and methods (like how we make computer chips), as well as both. Although the majority of contemporary technology is electronic, this does not mean that all technology is.
While the pursuit of scientific knowledge is important, it is the application of that knowledge that defines technology.
Therefore, the correct option is D.
