Answer: Well, shadows are visible to us because they are darker than the light around them. When an object is translucent it allows a lot of light to pass through. This amount of light makes the shadow very light and similar in color to the original light source.Why do translucent and opaque materials form shadow? Answer: Translucent and opaque materials form shadow because translucent objects block some light and opaque object block the light completely.A shadow appears the side of the objects furthest from the light source. * An opaque material makes a dark shadow. * A translucent material makes a faint shadow. * A transparent material cannot make any shadow. so it translucent

Why do light-fur mice survive LESS often on dark rocks, compared to dark-fur mice?
Answer:
for a creature with a lighter fur color it is next to impossible to blend into darker colored environments compared to darker fur colored creatures
The light fur mice survive less on the dark rocks compared to the dark fur mice. The reason is the light fur mice can be easily visible by the Predator and eaten by them.
What is adaptation?An adaptation is a process in which an organism tries to adapt with the environment in order to protect itself from the predator. There are different types of adaptation seen in the animal kingdom, such as mimicry.
An example is mice fur coloration on the dark rocks. Dark rocks have dark coloration. When dark-furred mice live on this type of rock, their colour will mix with the dark colour of the rock. As a result, they can't be clearly visible to the predator's eye. Predators that are present at a distance, such as birds can't distinguish between the rock and the dark mouse's fur. This increases their chance of survival. When a light fur-colored mouse lives on the dark Rock, it can easily be differentiated by the Predator and eaten by them.
Hence, light colour fur mice survives less than the dark fur mice on the dark Rock as they can easily be seen by predators.

why are onion cells yellow?
Answer:
I believe they are actually white but onions can be yellow when they are old or when they turn bad
Please answer as soon as you can
Answer:
Differences in air temperature cause movement in the air, which creates pressure.
The radiant energy from the Sun is transferred to the atmosphere, causing air movement. The air becomes less dense, so it rises.
As the air falls, it becomes more dense and cools to Earth’s surface.
The higher the latitude, the colder the climate; the lower the latitude, the hotter the climate.
1. Friction can cause a moving object to stop.
TRUE OR FALSE
Answer:
true
Explanation:
cus over a time when the objects energy get's reduced it would be halted by friction
Friction can absolutely causes a moving object to stop (stationary). So, the answer is True.
What is Friction?
It is a type of force that tries to slow down or stop the movement of a moving object when the two surfaces are touching each other.
To stop the object, surfaces also play an important role. For example, Rough surfaces produce more friction otherwise things would be just rolling.
Therefore, friction can cause a moving object to stop.

According to the Northern Hemisphere, all the statements given are exactly true.
What is the Northern hemisphere?It is one-half of the earth that is located in the north of the equator. It has about 90 percent of the world's population and most of the world's land.
Equinox means the duration of day and night are equal in length. There are two equinoxes in a year when the sun moves across the celestial equator, which lies directly above the earth's equator. The summer solstice occurs when the earth's pole is tilted towards the sun and receives more sunlight in the northern hemisphere. Winter solstice occurs when the earth's north pole is tilted away from the sun and receives less sunlight. Overall, the tilting and revolution of the earth is the main reason for the causation of different seasons.
Therefore, all the given statements are true with respect to the northern hemisphere.

At the end of meiosis ll, each of the haploid sex cells had only half the number of chromosomes as the original diploid cell. Why is this important?
Answer:
The cells at the end of meiosis II must have half the number of chromosomes because, if they didn't have, the reunion of both gametes with diploid number of chromosomes for example, in gametes would form twice the number chromosomes.
Plant hormones are chemical regulators that stimulate or inhibit growth depending on their concentration and type of tissue in which they
are found

LOW
HIGH
HORMONE CONCENTRATION
Based on the information in the graph, which is a correct conclusion about plant hormones?
F. They stimulate maximum root growth and stem growth at the same concentration.
OG. They stimulate maximum stem growth at low concentrations,
OH. They stimulate maximum root growth at high concentrations.
OJ. They stimulate maximum root and stem growth at different concentrations.
Answer:
OJ. They stimulate maximum root and stem growth at different concentrations.
Explanation:
Looking at the graph found in the attachment below, conclusions can be drawn about the effect ofnthe difference in concentration of plant hormones in the two different parts of the plants under consideration, the roots and the stem.p
Considering the roots;
maximum growth of the roots of plants as seen by the upward curve ofbthe arrow, is obtained when plant hormones are at low concentrations. However, with increase in the concentration of plant hormones, the growth of root diminishes as seen bynthe downward slope of the curve.
Considering the stems:
At low concentration of hoeprmones, the growth of stem is very minimal. However, with increase in concentration of plants hormones, a rapid upward shoot is seen in curve indicating a rapid increase in growth. Maximum growth occurs at high concentration of plant hormones.
Therefore, the proper conclusion is that, plant hormones stimulate maximum root and stem growth at different concentrations.

True
False
Answer:
False
Explanation:
Im not 100% sure tho
Waves run through substances, but they do not move the substances in the direction of the waves, and this is true for the first option as the wave transfers energy through the medium, causing the particles to vibrate.
What is the significance of the waves?Waves play a significant role in many areas of science and technology, such as in physics, where they are used to explain the behavior of light; in technology, where they are used for communication, as in radio; and in other fields, such as ultrasound and X-rays, where waves are used for the purpose of imaging.
Hence, waves run through substances, but they do not move the substances in the direction of the waves, and this is true for the first option as the wave transfers energy through the medium, causing the particles to vibrate.

A pH scale measures how acidic or basic a substance is.
Explanation:
The pH measures the H+ concentration in a substance. The more lower the pH, the more acidic the substance, the higher the pH, the more basic the substance. It measures from 0-14, with 7 being neutral. Anything less than 7, acidic. Anything above 7, basic.

1. Compare neutron stars and black holes.
2. explain the role of white dwarfs in recycling matter
3. Distinguish between an astronomical unit and a light year
4. How does a convection zone transfer energy?
Thanks!
Answer:
1. Both neutron stars and black holes are the corpses of stars that died in explosions known as supernovas. Black holes form when the most massive stars die and neutron stars form when stars not as large die. They both have a very strong gravitational pull, but a black hole's pull is stronger than a neutron star. Neutron stars will turn into black holes if the force of gravity breaks the resistance of electrons.
2. White dwarfs are degenerate, which means they can compress matter. The material in a white dwarf no longer undergoes fusion reactions, so it is supported only by electron degeneracy pressure. This causes it to be extremely dense, saving space and energy.
3. A light year is the distance light travels in a year while an astronomical unit is the average distance between the earth and the sun.
4. A convection zone transfers energy by radiation and conduction.
