Answer:
NucleusThe nucleus is the center of the cell. It holds the cell's DNA.
Ribosome(s)The ribosome(s) are made of RNA. They translate genetic code into amino acids that hold proteins for the cell.
Endoplasmic reticulumThe endoplasmic reticulum produces proteins similar to the ribosome(s) so that the cell can function on a day-to-day basis.
Hope this helps!
Answer:
Nucleus:
The nucleus is found in most cells. It is usually in the middle of animal cells. In plant cells, it is towards the edge. The nucleus hold the DNA, which is like a code that instructs the cell on what type of protein to synthesize.
Ribosome:
They are made of RNA and proteins, and are very small. This is where the cell, using instructions from the nucleus, synthesizes proteins by joining long chains of amino acids in a particular sequence.
Endoplasmic reticulum:
They can be either smooth or rough. Its main function is also to make proteins and lipids, and transporting and processing them.

Freh now ha an albedo of about 85%, and old now ha an albedo of about 50%. Which will reflect more of the un' radiation? Why?
Fresh snow has a higher albedo of about 85%, while old snow has a lower albedo of about 50%. Therefore, fresh snow will reflect more of the sun's radiation than old snow.
Albedo is a measure of the reflectivity of a surface, it is the ratio of the amount of light reflected by a surface to the amount of light incident on it. High albedo surfaces like fresh snow reflect more light and heat than low albedo surfaces like old snow. Fresh snow is a good reflector of sunlight because it has a high concentration of ice crystals, which scatter light in all directions.
Old snow has a lower albedo because it becomes more compacted over time, which reduces the number of ice crystals present, and because it may be dirty or covered with dust, which absorbs more light and heat. Additionally, old snow may have a layer of meltwater on top, which also has a lower albedo than the snow.
In conclusion, fresh snow has a higher albedo than old snow, and it reflects more of the sun's radiation back into space. This is why fresh snow appears brighter and whiter than old snow.

What are 3 negative impacts of rainforest removal?
3 negative impacts of rainforest removal:
The loss of trees and other vegetation can cause climate change, desertification, and increased greenhouse gases in the atmosphere.
Definition of Rain ForestA rainforest is an area of tall, mostly evergreen trees and a high amount of rainfall.
Rainforests are Earth’s oldest living ecosystems, with some surviving in their present form for at least 70 million years. They are incredibly diverse and complex, home to more than half of the world’s plant and animal species—even though they cover just 6% of Earth’s surface. This makes rainforests astoundingly dense with flora and fauna; a 10-square-kilometer (4-square-mile) patch can contain as many as 1,500 flowering plants, 750 species of trees, 400 species of birds and 150 species of butterflies.
Rainforests thrive on every continent except Antarctica. The largest rainforests on Earth surround the Amazon River in South America and the Congo River in Africa. The tropical islands of Southeast Asia and parts of Australia support dense rainforest habitats. Even the cool evergreen forests of North America’s Pacific Northwest and Northern Europe are a type of rainforest.
Rainforests’ rich biodiversity is incredibly important to our well-being and the well-being of our planet. Rainforests help regulate our climate and provide us with everyday products.
Unsustainable industrial and agricultural development, however, has severely degraded the health of the world’s rainforests. Citizens, governments, intergovernmental organizations, and conservation groups are working together to protect these invaluable but fragile ecosystems.

which part of the eye contains the cells that are sensitive to light?
Answer: The Retina
Explanation:
The retina is the innermost layer of the eye, lining the back of the eyeball. It is composed of several layers of nerve cells and other specialized cells, including the photoreceptor cells, which are responsible for sensing light.
There are two types of photoreceptor cells in the retina: rods and cones. Rods are responsible for detecting light in low-light conditions and they are more sensitive to light than cones. Cones, on the other hand, are responsible for detecting light in bright conditions and are responsible for color vision. Both rods and cones detect light by absorbing photons and triggering neural impulses that travel to the brain via the optic nerve.
In summary, the retina, the innermost layer of the eye, contains the photoreceptor cells, rods and cones, which are sensitive to light and allow us to see.

A carbon atom has 6 electrons however, its valency is 4. This is because the carbon atom has only 2 electrons in its first shell and 4 in the second shell.
Atomic carbon has six electrons: two core electrons in the 1s orbital and four valence electrons in the 2s and 2p orbitals. Because carbon has a valency of four, it can form bonds with four other carbon atoms or atoms of another monovalent element. This is known as carbon's tetravalency. If the number of electrons in the outer shell is four or less, an atom's valency is equal to that number. Otherwise, the valency is eight less the number of electrons in the outer shell.

Which sentence best describes how water affects rocks on the earth's surface?
O It applies pressure to rocks that causes them to metamorphose.
O It keeps sediment contained within its original location.
O It dissolves rock into small pieces and transports it elsewhere.
O It prevents erosion of rocks by protecting them from wind.
Water expands upon freezing. It then serves as a wedge. It gradually enlarges the fissures and splits the rock. By carrying away the minute rock particles lost in the split, liquid water conducts the act of erosion when ice melts.
How does water alter the surface of the Earth?Weathering and erosion brought on by water flow alter the features of the landscape. Localized weather patterns and climate are influenced by complex interactions, with the ocean playing a part. Water's special chemical and physical characteristics have a profound impact on the dynamics of the planet. The ions are carried by water as it dissolves the minerals in rocks. This procedure moves along quite slowly. But over millions of years, water in motion dissolves enormous quantities of rock. Particles of rock and soil are also picked up and carried by moving water.Rocks can dissolve minerals and become weaker over time when water penetrates into their pores and fissures. The process starts afresh when the water returns to the surface and evaporation takes place.To learn more about Earth’s surface, refer to:
