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 0. 50-kilogram ball is thrown vertically upward with an initial kinetic energy of 25 joules. Approximately how high will the ball rise? [neglect air resistance. ].
When it is freed, its kinetic energy and gravitational potential energy will be about equal (a little is lost to air resistance). Be aware that this will be based on the release point having no potential energy.
What happens to the ball's kinetic energy when it is hurled vertically up?The kinetic energy is canceled out. Kinetic energy is changed into potential energy in accordance with the rule of conservation of energy. At this height, potential energy is at its highest.
Gravitational potential energy is mgh.
mgh=25J
h=25J/(0.5kg x 9.81m/s^2) = 5.097m
So it goes about 5.1 meters.
Potential energy when a ball is hurled vertically up?The ball's kinetic energy progressively transforms into potential energy when it reaches its highest point. The ball's potential energy is at its highest point, where the ball's velocity falls to zero.

Describe at least two factors that contributed to the hostility between Maurice Wilkins and Rosalind Franklin
She would be in charge of the X-ray studies of DNA. Wilkins thought that Franklin would be his assistant.
What was the conflict between Wilkins and Franklin?Wilkins felt DNA was his dominant and Franklin was being hired as his deputy, not an independent scientist with her own mind and procedure. Wilkins and Franklin never got along. Markel loudens a chorus of their colleagues on why. Watson blamed Franklin for declining to accept her role as Wilkins' assistant.
He mistook her for a new secretary, and it emerge that they never established a good working connection as fellow scientists. Franklin had gotten the impression she would be waged alone in the lab; Wilkins saw her in a more supportive role to his work.
So we can conclude that Rosalind Franklin acquires images of DNA using X-ray crystallography, an idea first raised by Maurice Wilkins.

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.

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.
