A lab investigation involves using food coloring to track diffusion. Which action should students take to avoid damaging their clothing? Wear old, stained clothing to the lab. Wear a lab apron or lab coat over clothing. Have plenty of paper towels for cleaning up spills. Tuck sleeves into long safety gloves.
While working in labs with chemicals or specimens one should follow good laboratory practices. Professional conduct and manner should be maintained during working in labs.
The action that should be taken by a student is:
Option B. Wear a lab apron or lab coat over the clothing.
The good lab practices can be explained as:
To avoid staining clothes individuals should wear lab coats over their clothes.Lab coats avoid staining and splashing your skin and clothes from chemicals and dyes.Lab coats are designed to protect against corrosive chemicals from soaking into the skin.Therefore, the student should wear lab coats and aprons.

A drought is a long period of abnormally low precipitation. Suppose a drought occurred in Yellowstone National Park from 1916 to 1917. Predict how a graph line would appear for this time period. Explain your prediction in terms of the effect on resource availability.
Answer:
A drought is a long period of abnormally low precipitation. Suppose a drought occurred in Yellowstone National Park from 1916 to 1917. Predict how a graph line would appear for this time period. Explain your prediction in terms of the effect on resource availability.
Explanation: The graph line would have a downward trend because the amount of bison would start to decrease. Droughts heavily impact grassland ecosystems. A drought would increase the risk of a wildfire starting causing the bison to lose their habitat. The drought would also result in reduced plant growth. Therefore the bison would die off either because they were impacted by a wildfire, because they don’t have grass to eat etc.

why is sunlight important for life on earth
Answer:
drives weather, ocean currents, seasons, and climate
Explanation:
The sun has extremely important influences on our planet: It drives weather, ocean currents, seasons, and climate, and makes plant life possible through photosynthesis. Without the sun's heat and light, life on Earth would not exist.

Which is an accurate statement about the different types of radiation emitted by the Sun? Select the two correct answers
Radiation with the shortest wavelengths is emitted steadily and constantly from the sun.
Radiation with the longest wavelengths is emitted steadily and constantly from the sun.
Radiation with the longest wavelengths is most likely to cause wide variation in Total Solar Irradiance.
Radiation with the shortest wavelengths is most likely to cause wide variation in Total Solar Irradiance.
Answer:
Radiation with the longest wavelengths is emitted steadily and constantly from the sun.
Radiation with the shortest wavelengths is most likely to cause wide variation in Total Solar Irradiance.
Radiations with the longest wavelengths is emitted steadily and constantly from the Sun and the radiations with the shortest wavelengths is most likely to cause wide variation in the total solar irradiance. Thus, the correct options are B and D.
What are the solar radiations?
Solar radiation is often called as the solar resource or simply sunlight. It is a general term which is used for the electromagnetic radiations that are emitted by the Sun. Solar radiations can be captured and turned into useful forms of energy, such as heat and electricity, using a variety of different technologies.
The radiations with the longest wavelength is emitted steadily and constantly from the Sun and the radiations with the shortest wavelengths is most likely to cause wide variation in the total solar irradiance.

Answer:
I think it's the last one! "They have the same set of product molecules"

Fraternal twins, while conceived at the same time, are not genetically identical.
Which statement best explains why these siblings are genetically different from each other
Answer:
Fraternal twins are also called dizygotic twins. And the difference between fraternal and identical twins is that fraternal twins derive from two different eggs. Fraternal twins may be the same gender, they may have many of the same characteristics, but also may be very different from each other and, in fact, share half of their genes just like their sisters and brothers. It's important to recognize that the difference between fraternal twins and monozygotic, or identical twins, is that monozygotic twins result from the fertilization of a single egg with a single sperm and then during the embryonic development, or during the cell splits, those massive eggs split into two individuals, which later develop into two offspring.
