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.

How does carbon dioxide enter the atmosphere?
A)Carbon dioxide is only released into the atmosphere by human activities.
B)Carbon dioxide is only released into the atmosphere by animals and bacterial decomposers.
C)Carbon dioxide is only released into the atmosphere by plants, animals, and bacterial decomposers.
D)Carbon dioxide is released into the atmosphere by plants, animals, bacterial decomposers, and human activities.
Carbon dioxide is released into the atmosphere by plants, animals, bacterial decomposers, and human activities.
What is Carbon dioxide?An essential component of the Earth's atmosphere is the colorless gas known as carbon dioxide .
Carbon dioxide exists in the atmosphere naturally and is also released into the atmosphere as a result of human activity such as the burning of fossil fuels, making cement, and decomposers.
In addition to being necessary for plant growth, carbon dioxide also plays a role in controlling the climate and decomposers of the planet.
One carbon atom is covalently doubly linked to two oxygen atoms in each molecule that makes up carbon dioxide, a chemical compound.
When the temperature is ambient, it exists as a gas.
Carbon dioxide functions as a greenhouse gas because it absorbs infrared light despite being transparent to visible light when it is in the air.

Two astronauts, one of mass 55 kg and the other of mass 85 kg, are initially at rest together in outer space. They then push each other apart. How far apart are they when the lighter astronaut has moves 12 m?.
As a result, the heavier astronaut moved 19 meters whilst the lighter astronaut moved 12 meters.
Calculation:Mass of the first astronaut, m1 = 55 kg
Mass of the second astronaut, m2 = 85 kg
Distance moved by the first astronaut, d1 = 12 m
d2 = distance traveled by the second astronaut.
using the law of conservation of momentum, we can say
m1d1 = m2d2
So that, d2 = m1d1 / m2
d2 = (55 * 12) / 85
d2 = 660 / 85
d2 = 7 m
If we then account for the 12 m that the first astronaut traveled. According to our calculations, the second astronaut traveled a total distance of 7 + 12 = 19 m.
When an astronaut is in space, does their weight change?Astronauts are basically weightless in space since there is no gravity pulling them down. Investigating the distinction between mass and weight is crucial. Astronauts' bodies remain the same shape and size even though they may not weigh anything and can move around freely in space.
Are astronauts heavier in space or on Earth?The astronaut's mass won't differ between the Earth and the Moon. Although weight of a person varies depending on where they are on the earth, mass is a fixed figure. Weight is the force of gravity acting downward on a person or any other body.

a.Trees shade buildings which reduces the use of energy derived from fossil fuels.
b.Trees remove carbon dioxide and add oxygen the atmosphere.
c.Trees filter particulates and polluting gases from the atmosphere.
d.All of the above
The sentence that best explains how trees help conserve energy and reduce pollution in cities is d.All of the above.
What ways do trees minimize pollution?The carbon dioxide gas in the atmosphere is absorbed by plants for photosynthesis if trees are grown in big numbers. Plants absorb carbon dioxide, which is produced when fossil fuels are burned, and thus helps to reduce pollution.
Buildings are shaded by trees, which lowers the need for energy derived from fossil fuels. Trees improve the atmosphere's oxygen content and eliminate carbon dioxide. The atmosphere is cleaned by trees of particles and harmful gases.

Why can humans not rely on the transport method used in small organisms what can they do to overcome this
Humans cannot rely on the transport methods used in small organisms because we have much larger and more complex bodies that require specialized systems to transport materials such as oxygen, nutrients, and waste products.
Small organisms, such as single-celled organisms, can rely on diffusion, which is the movement of molecules from an area of high concentration to an area of low concentration, to transport materials throughout their body. However, diffusion is not efficient for larger organisms like humans, as the distance that materials need to travel is much greater.
To overcome this, humans have developed specialized transport systems such as the circulatory system and the respiratory system. The circulatory system, which includes the heart, blood vessels, and blood, is responsible for pumping oxygen and nutrients to the cells and removing waste products. The respiratory system, which includes the lungs, trachea, and bronchi, is responsible for getting oxygen into the body and getting rid of carbon dioxide. Additionally, humans have a complex nervous system which coordinates and controls all the vital functions of the body.
In summary, Humans rely on specialized transport systems like circulation, respiration, and nervous system to overcome the limitations of diffusion, which is the transport method used in small organisms.

which part of the eye changes the shape of the lens?
Answer: The ciliary muscle
Explanation:
The ciliary muscle is a ring-shaped muscle located around the circumference of the eye's lens. It is responsible for changing the shape of the lens by contracting or relaxing.
When the ciliary muscle contracts, it loosens the zonules (fibers that hold the lens in place) that attach the lens to the ciliary body. This allows the lens to become flatter, which is necessary for focusing on distant objects. On the other hand, when the ciliary muscle relaxes, the zonules tighten, causing the lens to become thicker and more rounded. This allows the eye to focus on close objects.
This process is called "accommodation", by which the eye is able to adjust the shape of the lens to focus on objects at different distances.

Gene flow is the mechanism that causes the gene pool of two populations to become similar.
Gene flow is the process of transfer of genes in and out of a population. The new genes introduced into the population through gene flow then reproduce with the existing genes of the population and that is how the similarity of genes occurs.
Gene pool is the collection of the entire genome (genes and alleles) of a population whose organisms are able to reproduce. A large gene pool consists of varying genomic diversity which is considered to be able to adapt better in the unfavorable conditions.

Is the gene that causes hemophilia recessive or dominant? Use the image to explain your reasoning.
I don't see a provided imagine but I can answer your question.
The gene that causes hemophilia is recessive. Hemophilia is caused by a mutation in the gene that codes for clotting factors VIII (hemophilia A) or IX (hemophilia B). The normal version of these genes is dominant, meaning that it masks the effects of the mutant gene. But when there are two copies of the mutant gene, one inherited from each parent, the lack of clotting factors leads to the bleeding disorder. The individual must inherit two copies of the gene (one from each parent) in order for the disorder to manifest. Hemophilia is often inherited in an X-linked recessive pattern, which means that the gene responsible for the disorder is located on the X chromosome.
