The human body has four types of tissues, and the eye contains all four. Which statement correctly pairs the part of the eye
with the tissue type? (1 point)
Epithelial tissue is found in the sclera, the white part of the eye.
Muscle tissue is found in the iris, the colored part of the eye.
O Connective tissue is found in the comea, the outermost lens of the eye.
Nerve tissue is found in the retina, the rods and cones at the back of the eye.
Answer:
The correct answer is D) Nerve tissue is found in the retina, the rods and cones at the back of the eye.
Explanation:
The rods and cones are photoreceptors (that is nerve cells within the eyes that can sense light) which is situated in the retina.
These photoreceptors also sense colours and send these signals into the optic nerve for transmission to the brain.

Which of the following statements is true?
Plasma can be found in lightning and stars.
Liquids have a fixed shape but a variable volume.
Bose-Einstein condensates form at very high temperatures.
All of the above.
Answer:
Plasma can be found in lightning and stars.
Explanation:
Plasma is a state of matter that lacks a fixed volume and a fixed shape and consists of charged particles called ions. The sun and other stars consist of plasma. Plasma is also found naturally in lightning and the northern and southern lights.
The true statement is: Plasma can be found in lightning and stars and the correct option is option 1.
Plasma is the fourth state of matter, distinct from solid, liquid, and gas. It is an ionized gas consisting of a mixture of positively charged ions and free electrons. In this state, atoms have lost some of their electrons due to high temperatures or strong electromagnetic fields. This creates a highly conductive and energetic environment where particles move freely and interact with electromagnetic forces.
Plasma is commonly found in high-temperature environments like stars, lightning, and fluorescent light tubes. It also plays a crucial role in various industrial and technological applications, such as plasma TVs, fusion reactors, and certain medical treatments.
Thus, the ideal selection is option 1.

Jerome is learning how the model of the atom has changed over time as new evidence was gathered. He has images of four models of the atom, but they are not in the correct order. An image at the left labeled W with overlapping red and blue balls in the center with a circular fuzzy green cloud outside them. An image at center-left labeled X with a purple ball in the center surrounded by overlapping concentric black ovals, each with a small green ball on each of the 6 ovals. An image at center right labeled Y with a large black cross in a purple circle with a black line around the purple, with 10 small green balls dispersed within the purple circle. An image at right labeled Z with a purple center outlined in black with two concentric black circles around the center, the inner circle having 2 small green balls on it and the outer circle having 8 small green balls on it.

B. Less on the moon.
Mass and WeightAn object's mass is a measure of its inertial property, or the quantity of matter it contains.The weight of an object is a measure of the force imposed by gravity on the object, or the force required to support it.As the moon's gravitational force is roughly one-sixth that of the Earth's, one's weight on the moon would be roughly one-sixth that of the Earth.Mass is the amount of matter or “stuff” in the body.

A student reports the density of an article to be 1.92 g/mL. The accepted value of density is 1.89 g/mL. Calculate the student's percent error.
Answer:
1.59%.
Explanation:
The following data were obtained from the question:
Measured density = 1.92 g/mL
Accepted density = 1.89 g/mL
Percentage error =...?
The percentage error error of the student can be obtained as follow:
Percentage error = |Measured density – Accepted density |/Accepted density × 100
Percentage error = |1.92 – 1.89|/1.89 × 100
Percentage error = 0.03/1.89 × 100
Percentage error = 1.59%
Therefore, the student percentage error is 1.59%
It is 762 miles from here to Chicago. An obese physics teacher jogs at a rate of 5.0 miles every 20.0 minutes. How long would it take him to jog to Chicago if he jogged continuously and REALLY wanted to get there?
Answer:
3,048 minutes
Explanation:
762 divided by 5
that number times 20
The time required for a physics teacher to jog continuously and REALLY wanted to get there will be 50 hours and 48 minutes.
What is speed?The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the speed formula
Speed = Distance/Time
It is 762 miles from here to Chicago. An obese physics teacher jogs at a rate of 5.0 miles every 20.0 minutes.
Then the speed of the physics teacher will be
Speed = 5 / (20 / 60)
Speed = 15 miles per hour
The time required for a physics teacher to jog continuously and REALLY wanted to get there will be
15 = 762 / T
T = 762 / 15
T = 50.8 hours
T = 50 hours and 48 minutes
The time required for a physics teacher to jog continuously and REALLY wanted to get there will be 50 hours and 48 minutes.

ANALYZE Define a system you interact with every day. Is the system
open, closed, or isolated? How do matter and energy flow into, out
of, or within the system?
Answer:
A system that we use daily or almost every day is, for example, when boiling water for cooking.
Explanation:
This is the case of an open system.
Boiling water in a pot without a lid, exchanges heat energy and mixes with its surroundings when it enters a gaseous state.
The energy introduced into the system by the fire transforms the water into gas, which is released back into the environment. Without that constant heat injection, the water will stop boiling; and without room to get out, the steam (matter) will increase the pressure until the pot burst.
You can find examples like these anywhere, knowing the definition of each system:
Open systems. The most predominant of all, are characterized by exchanging energy and / or matter with the environment that surrounds them, either taking from it, expelling towards it or both. Closed systems. Unlike the previous ones, they exchange energy (heat, work) with the outside, but never matter (their mass remains intact). Isolated systems. They are so called because they do not exchange energy or matter of any kind with their environment, they are considered a system disconnected from the dynamics around them. Completely isolated systems do not really exist in the universe, so they are considered cases of abstraction in determined periods of time. They are assumed in thermodynamic equilibrium.What was the commonality between Becquerel and the Curies in terms of their work? polonium radium uranium cesium

What force opposes gravity and keeps objects from falling to the center of
the earth?
La fuerza de la gravedad depende de la masa (el peso) de cada objeto. La fuerza con que se atraen dos objetos es proporcional a su masa y disminuye rápidamente en el momento en que los separamos. De hecho, nosotros también atraemos objetos con ‘nuestra’ fuerza gravitatoria, pero pesamos tan poco que no podemos percibirlo. En cambio, el Sol es tan grande que es capaz de mantenernos girando a su alrededor a pesar de estar muy lejos. La Luna también ejerce su propia fuerza gravitatoria, pero, como es más pequeña y ligera que la Tierra, si nos pesásemos sobre su superficie veríamos que pesamos unas seis veces menos que en la Tierra.
Podríamos preguntarnos por qué la Luna no cae sobre la Tierra al igual que una manzana cae del árbol. La razón es que nuestro satélite nunca está quieto. Se mueve constantemente a nuestro alrededor. Sin la fuerza de atracción terrestre, se alejaría flotando en el espacio. Gracias a esta combinación de velocidad y distancia de nuestro planeta, la Luna siempre está en equilibrio, ni cae ni se aleja. Si se moviera más rápido, se alejaría, si se moviera con más lentitud, ¡caería!
Hemos dicho que la fuerza de la gravedad también depende de la distancia. Si nos alejásemos lo suficiente de la Tierra, escaparíamos a su fuerza de atracción. Y eso es lo que tratamos de hacer con las naves espaciales. Necesitamos superar la llamada ‘velocidad de escape’, que es aproximadamente 11,2 km/s (a esa velocidad, podríamos viajar de Londres a Nueva York ¡en tan solo 10 minutos!). Cuando un cohete alcanza esa velocidad, ya es libre para viajar por el sistema solar.
Dentro de una nave en órbita, no sentimos la fuerza de la gravedad terrestre. Los objetos no caen, sino que flotan, así que si saltas, no regresas al suelo. Es lo que les ocurre a los astronautas cuando están a bordo de una estación espacial que orbita alrededor de la Tierra.
