No, a cell could not live without an endoplasmic reticulum. The endoplasmic reticulum is essential for protein and lipid synthesis, processing, and transport within the cell. Without this organelle, the cell would not be able to properly function and would eventually die.

Everything takes up space and has weight so why doesnt atom.you can't feel it because its to small to feel or see,touch etc.

I think it's gotten close to $50 per kilo. I'm invested in a stock SRSR Sarissa Resources Inc. and I've heard $22-23 per pound batted around the last few months. The metals websites with the prices are too expensive for me to get a membership, so I just read around to see what shows up in articles from time to time.

They argued that white was the superior race. And that immigrants would destroy the country

1. Interplanetary debris that was not gravitationally swept up by the planets during the formation of the solar system.

2. Material from the asteroid belt.

3. The solid remains of comets that once traveled near Earth's orbit.

Dawn is a time of day, when the sun first appears in the sky. As such, it is not exactly made of anything.

Yes, several spacecraft have successfully landed on Mars. Some notable examples include the Mars rovers Spirit, Opportunity, Curiosity, and Perseverance, as well as the InSight lander. These missions have provided valuable information about the Martian surface and environment.

He developed an equation from which one can derive the probability of an electron having a specific value for location or velocity.

He had nothing whatsoever to do with the discovery of neutrons.

sensible fluid losses ar those the person is aware of such as through wound drainage, GI tract losses and urination. Insensible fluid losses may occur without the person's awareness. Insensible losses occur daily through the skin and lungs.

Yuri Gagarin became the first human to journey into outer space on April 12, 1961, when he orbited Earth once aboard the Vostok 1 spacecraft. His spacecraft traveled approximately 200 miles into space during the historic flight.

Stars are most stable during the main sequence stage of their life cycle. During this stage, stars maintain a balance between the inward force of gravity and the outward force of nuclear fusion in their cores. This equilibrium allows them to burn hydrogen efficiently and emit a steady amount of energy.

The temperature of the abyss varies depending on the location, but it is generally close to freezing, around 0-3 degrees Celsius. At certain depths where hydrothermal vents are found, the temperature can rise significantly, reaching up to 400 degrees Celsius.

The umbilical cord connects the navel of a fetus with the placenta. When the baby is born the umbilical cord is cut. The belly button is the location where the umbilical cord connected to the placenta.

Umbilical cord is located at the umbilicus of the new born. The other end is attached to the placenta. Fetus gets the nourishment from the mother via umbilical cord.

Hot countries typically produce salt through evaporation of seawater in shallow ponds called salt flats. The water evaporates under the sun, leaving behind salt crystals which are then collected, processed, and refined for consumption or industrial use. This method takes advantage of the high temperatures and low humidity in hot regions to speed up the evaporation process.

the most common combination, and it is over 99.99% is two eyes and one head of hair. Some sadly have no hair, and even less fortunate, some have one or no eyes. But seriously, it depends where you are. In Europe light eyes and light hair is much more common than in the good ole USA. In the US Brown/brown is the most common.

A week after the Full Moon the Moon looks like a semi circle again, this phase is called ''Third Quarter''

Information on a physical medium like paper can include text, images, drawings, diagrams, and any other visual or written content that can be physically printed or written on the paper surface.

An average adult blue whale, the largest animal on Earth, weighs roughly 200,000 to 300,000 pounds. To reach 4,000,000,000 pounds, you would need about 13,333 to 20,000 blue whales collectively.

I assume you mean Friday, October 13, 1307. This date is believed by some to be the origin of the "Friday the 13th" superstition. On this date, thousands of members of the Knights Templar, a prominent religious order in Europe, were rounded up and arrested by the French king, who accused them of various crimes of heresy and fraud, most of which turned out later to be false.

It all has to do with wavelengths of energy. The wavelengths that we absorb and sense as heat tend to be the longer wavelengths just below the visable spectrum, i.e infrared. The visible wavelengths of energy that we see as light cover a range we perceive as the spectrum. The longest wavelengths the eye can detect are red, the shortest blue to violet. The hotter something is the faster its molecules vibrate and the shorter the wavelengths of energy it gives off. Once the frequency enters the visible range the item appears to glow. It would start with red-hot. As it gets hotter it might give off energy across the visible spectrum and become white hot. If it gets really hot it starts going beyond the visible spectrum and the only thing you could see would be the blue wavelengths. You can't see the higher wavelenthgs just like you can't hear the high pitch of a dog whistle. We tend to associate warm with things in the red to yellow end of the spectrum, like fire or a redhot poker because that is what we are used. Things that are blue tend to be just giving off blue light -- short, high-energy wavelengths but in small quantity. So we think of things that are blue as being cold. We never experience true blue heat because if you were standing next to something glowing blue-hot you would be burnt to a crisp. So the blue stars' are giving off a lot more enregy and in higher wavelengths than our cooler yellow sun, but luckily they are far enough away that they are just a cool-blue dot in the night sky.

Related disciplines and approaches under ecology include environmental science, conservation biology, population ecology, community ecology, landscape ecology, and ecosystem ecology. These disciplines study interactions between organisms and their environment at different levels of organization, from individuals to ecosystems, to understand how ecosystems function and how they can be managed and conserved.

I value God's creation by recognizing its inherent beauty and complexity, understanding the interconnectedness of all living things, and striving to be a good steward of the Earth by caring for the environment and respecting all forms of life.

Bats use high-frequency ultrasound waves, typically between 20 to 200 kilohertz, for their echolocation radar system. These sound waves can travel long distances and bounce off objects, allowing bats to navigate and hunt in the dark by interpreting the echoes.

The formula for working out Potential enery is:

PE = mgh - where g equals to the acceleration due to gravity (which is 10 newtons)

- mass should be in Kg's

- and height in meters

- final answer should be in Joules (J)

Therefore substitute it in :-)

Pe = (500g = 0.5kg) x (10N or more exact 9.8N) x (2 meters)

Pe = 10 Joules of potential energy with a object weighing 500g (or 0.5 kg) and from a height of 2 meters

Some instruments that gather and record information from a distance include satellites, drones, radar systems, and telescopes. These tools allow for remote sensing and monitoring of a variety of parameters such as weather patterns, land use changes, and astronomical observations.
