The statement 'scientists used radioactive dating to study the age of material from the moon and Earth' best explains how scientists confirmed that the moon formed around the same time as Earth.
What is radioactive dating?Radioactive dating is a well-known technique used to date the age of specific rocks (in this case, moon rocks).
Radioactive dating uses the average life of radioactive isotopes to determine the age of a particular rock.
Radioactive isotopes used in radioactive dating may include, among others, Carbon-14 and Hydrogen-3 (tritium).
In conclusion, the statement 'scientists used radioactive dating to study the age of material from the moon and Earth' best explains how scientists confirmed that the moon formed around the same time as Earth.

Environmental Science :)
The part of the following options that are not a long-term effect of mining in the Picher Mining District is the increased amounts of vegetation.
Picher Mining District is an area located in Ottawa, Northeast of Oklahoma. In this area, mining activities are being carried out and these activities can have long-term detrimental effects or complications to respiratory organs.
Miners are required to practices safety rules during mining activities and periodically go for check-ups to extract any harmful substances away from the body system.
Therefore, we can conclude that in an area where mining activities are being carried out, the effect of mining which is not a long-term effect is the increased amounts of vegetation.

3. population
2. community
4. ecosystem
5. biome
5. biosphere
Explanation:
Biological term related to the number of individual organisms from smallest to largest is organisms, populations, communities, ecosystem, biome, and biosphere.
An organism is a single organism or unity entity in a population, a population is a group of similar individuals that combinedly form a community with other types of population.
A community is a group of various types of populations, that interact with one another. If a community interact with other biotic and abiotic factors it is known as an ecosystem that together with other ecosystems forms a biome

What is a possible result of an increased amount of CO2 in the atmosphere?
Answer:
There are no options to this question, however, it can be answered using general knowledge. The answer is GLOBAL WARMING
Explanation:
Carbon dioxide, commonly called CO2, is one of the gaseous constituent of air. It is considered to be the most important greenhouse gas i.e. gases that have the ability to trap heat from the surrounding atmosphere. Due to this ability, CO2 in addition to other gases like methane are known to contribute to a phenomenon called GLOBAL WARMING.
GLOBAL WARMING is an increase in the atmospheric temperature of the Earth due to the effect of greenhouse gases. Global warming is a concern for the world populace, hence, an increase in the concentration of gases like CO2 in the atmosphere will lead to GLOBAL WARMING (an increase in Earth's atmospheric temperature).
When making yogurt, bacteria and milk are mixed together and set in a warm area. The container is sealed and no gasses are allowed to enter the container. After 24 hours the container is opened, and there is still no gas. Upon tasting the mixture there is a tart flavor. What type of respiration were the bacteria most likely carrying out?
A.
photosynthesis
B.
alcoholic fermentation
C.
lactic acid fermentation
D.
aerobic cellular respiration
Answer:
When making yogurt the tart flavor get in the end is more likely because the bacteria have carried out a type of respiration named lactic acid fermentation (option C).
Explanation:
The process of obtaining yogurt from whole milk involves the association of the bacterial species Streptococcus and Lactobacillus. In order to carry out the lactic acid fermentation that produces yogurt, the bacteria act in a different way:
Streptococcus is in charge of removing the oxygen from the milk product.Lactobacillus promotes the conversion of lactose sugar into lactic acid.This fermentation process leads to the conversion of milk into a coagulated and tart flavor product.
Other options are not correct because:
A. Photosynthesis : is the process that occurs in plants to obtain chemical energy from sunlight.
B. Alcoholic fermentation: in this chemical process alcohol is obtained from the fermentation of a sugar.
D. Aerobic cellular respiration: does not involve fermentation, but the series of processes that convert glucose into energy.
the sequence of the bases in DNA is most important for which of the following?
A. allowing the DNA to have the shape necessary for replication.
B. preventing mutations from occurring during DNA replication
C. helping from the sugar-phosphate backbone of DNA molecules.
D. providing the instructions for the traits of an organism.
Answer:
D. providing the instructions for the traits of an organism
Explanation:
It can't be A because RNA is used for replication not DNA
It can't be B because mistakes in the RNA are what causes mutation.
It can't be C because sugar phosphate wouldn't be in the nucleus.
It has to be D because that is the purpose in DNA is to give instructions to the cell
China's economy is growing very quickly and requires a large amount of energy. Most of the energy consumed by the country comes from a nonrenewable energy source. Which of the following is a nonrenewable energy source?
A
coal
B
hydroelectric
C
solar
D
wind
Fun fact ; I made this sentence while brushing my teeth , you can tell with how this sentence is lowercased and multiple typos
Answer:
A non-renewable source of energy is coal.
Explanation:
The mineral coal is a brown or black rock, of sedimentary origin, that comes from organic matter, so it is considered a fossil fuel.
Currently, coal is used as an energy source, since its combustion produces a great amount of heat. However, the speed with which coal is consumed is faster than its production —which can last millions of years— so it is considered a depletable or non-renewable energy source.
The other options, such as hydroelectric, solar and wind energy are renewable energy sources.

The arthropods with three body sections, three pairs of legs, and one or two pairs of wings are the _______
Answer:
Insects
Explanation:
Insects, like ants, have three body sections, the head, thorax, and abdomen. They have three pairs of legs, three on each side of the body, six legs. And some ants have wings.
The arthropods with three body sections, three pairs of legs, and one or two pairs of wings are the insects.
What are the characteristics of arthropods?Arthropods are invertebrate animals with an exoskeleton, a segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda.
Insects such as ants, dragonflies, and bees. Arachnids such as spiders and scorpions. Myriapods (a term which means “many feet”) such as centipedes and milipedes. Crustaceans such as crabs, lobsters, and shrimp.
All arthropods posses an exoskeleton, bi-lateral symmetry, jointed appendages, segmented bodies, and specialized appendages. The major arthropod classes can be separated by comparing their number of body regions, legs, and antennae.

does anyone know how to make my voice deeper I'm ftm so I need help
Hey I have a suggestion if you're still wondering!
So this method actually helped me a lot.
So start by tilting your head downward and by humming in your regular pitch. Then slowly raise your head while continuing to hum. And finally tilt your head back down. And now your voice is deeper than before you started the process.
This helps your vocal cords to become deeper. You can do this as many times you need until you're satisfied. But please be careful and don't do it too much. The first time I did it, I felt really proud. And the day after my throat hurt. I'd say that doing it only once actually lasts a couple hours!
