Answer:
They turn moist red litmus paper blue and they react with metals.
They turn moist red litmus paper blue because they have a pH range of 8-14, hence they are indicated by a blue colour of the litmus.
They react with metals because they are reactive, the reaction forms a metal salt and water.

Isotopes are forms of the same element that have a different number or protons.
TRUE or FALSE ?
Answer:
false Isotopes. An isotope is one of two or more forms of the same chemical element. Different isotopes of an element have the same number of protons in the nucleus, giving them the same atomic number, but a different number of neutrons giving each elemental isotope a different atomic weight.

Genetic engineering is best described as:
A. changing the RNA of a living thing to change its characteristics.
B. using certain genes to accomplish engineering tasks.
C. using genetic structures as examples for modern engineering practices.
D. changing the DNA of a living thing to change its characteristics.
Answer:
D. changing the DNA of a living thing to change its characteristics.
Explanation:
Genetic engineering is the process of using recombinant DNA (rDNA) technology to alter the genetic makeup of an organism. Traditionally, humans have manipulated genomes indirectly by controlling breeding and selecting offspring with desired traits.
Genetic engineering is the field of science that changes the DNA of the living organism to alter its original characteristic. Thus, option D is correct.
What is Genetic engineering?Genetic engineering is the manipulation and modification of genetic makeup like the DNA of the organism by deleting, altering, and adding the nucleotide bases.
It uses various techniques and tools to alter the DNA and hence, modify its characteristics. It uses RDT and another process to manipulate the genome and produces desired traits by controlled breeding.
Therefore, genetic engineering changes the DNA of a living organism.

In an energy pyramid, what organisms have the most energy available? *
1.) herbivores
2.) producers
3.) carnivores
4.) top predator
Answer:
I think producers
Explanation:
In an energy pyramid, producers have the most energy available. The correct option is 2.
What is energy pyramid?A graphic that depicts the biomass or bioproductivity at each trophic level in an ecosystem is called an ecological pyramid.
An ecosystem's energy transfer from one trophic, or feeding, level to the next is depicted by an energy pyramid.
The model is a figure that contrasts how much energy different trophic levels of species use. Kilocalories are the units used to measure the energy in an energy pyramid (kcal).
The producers are located in the base of the pyramid, which is also its greatest level.
The amount of energy diminishes and the levels get smaller as you progress up the pyramid, via the trophic levels to primary, secondary, and tertiary consumers.
Thus, the correct option is 2.

What piece of evidence supports the theory that volcanic eruptions formed Earth's early atmosphere?
O Volcanoes expel gases with chemical compositions which closely match the ratios of gases in air not caused by photosynthesis.
O Volcanoes are clustered near the equator, so their gas output spreads over Earth's surface.
O Volcanoes expel a mixture of gases consisting almost entirely of water vapor and oxygen
Volcanic eruptions are inversely proportional to local atmospheric pressure.
Answer: Volcanoes expel a mixture of gases consisting almost entirely of water vapor and oxygen
Volcanic eruptions are inversely proportional to local atmospheric pressure.
Explanation: I think
Volcanoes expel a mixture of gases consisting almost entirely of water vapor and oxygen.
What is volcanoes?
Volcanic eruptions are inversely proportional to local atmospheric pressure.
An opening in the crust of a planet or moon known as a volcano allows molten rock, heated gases, and other things to erupt. As layers of rock and ash accumulate from numerous eruptions, volcanoes frequently take the form of a hill or mountain.
There are three types of volcanoes: active, dormant, and extinct. Active volcanoes have recently erupted; they are likely to do so once more. Volcanoes that are dormant have not erupted in a very long time yet could do so in the future. It seems unlikely that extinct volcanoes will erupt in the near future.
Therefore, Volcanoes expel a mixture of gases consisting almost entirely of water vapor and oxygen.

There are some clouds forming in the sky on a hot day, but inside the clouds, there are freezing temperatures. Which form of precipitation would you expect?
A) Hail
B) Rain
C) Sleet
D) Snow
Answer:
C) Sleet is the correct answer
I hope it's help for you
Have a nice day
Answer:
Hail - A
Explanation:
The temperature outside of the clouds is very hot which caused the colder water in the clouds to condensate. When the clouds got colder, the water began to freeze which would cause tiny drops of ice, i.e, hail to fall to the ground. Hope this helps :)

A sample of DNA is collected from an organism. It is analyzed and determined that 20% of the DNA is made up of the base adenine. Based on this information, which of the following correctly lists the amounts of the three remaining bases for this sample
A 20% cytosine, 20% thymine, 20% guanine
B 30% cytosine, 209. thymine, 30% guanine
C 10% cytosine, 30% thymine. 40% guanine
D 30% cytosine, 30% thymine, 20% guanine
Explanation:
According to the Chargaff's rules the DNA from any cell of all organisms should have a 1:1 ratio (base Pair Rule) of purine bases [for the DNA cytosine, thymine and for the RNA uracil] and pyrimidine bases [guanine and adenine for RNA and DNA]. The amount of guanine should be equaled to cytosine and the amount of adenine should be equaled to thymine. You can follow this rule in both strands of the DNA.
According to the information given above, the amount of the three remaining bases for this sample is 30% cytosine, 20% thymine, and 30% guanine. Thus, the correct option is B.
What are Bases?Bases may be defined as the monomer of nucleic acids such as DNA or RNA. These nucleotide bases are composed of a pentose sugar, and a phosphate group.
There are four types of nucleotide bases that are generally found in any nucleic acid sequence. They are adenine, guanine, thymine, and cytosine. But in RNA, Thymine is replaced by Uracil.
According to Chargaff's rule, the amount of adenine is always equal to the amount of thymine, while the amount of guanine is always equal to the amount of cytosine.
∴ A = T : G = C.
If the amount of adenine is 20%, the amount of thymine is also 20%. Together, they constitute 40% of DNA, now the remaining is 60%.
This 60% is then equally divided into two parts between 30% cytosine and 30% guanine.
Therefore, the amount of the three remaining bases for this sample is 30% cytosine, 20% thymine, and 30% guanine. Thus, the correct option is B.

A,it dissolves many substances.
B,Itis slightly more acidic than air.
C,Its solid

A
Please mark brainliest if correct. Have a blessed day. :)
One of the unique properties of water is that it has the capacity to dissolve many substances. The correct option, in this case, would be A.
Water is often referred to as a universal solvent. This is because the liquid has the capacity to dissolve more substances than any other liquid known to exist in nature.
The ability of water to dissolve a wide range of substances has been linked to its chemical and physical properties, especially its polar nature. Water molecules are polar with slightly positive and negative charges, Thus, they are able to attract other types of molecules

what are the four layers that make up the earth?
Answer: The 4 layers that make up the earth is the crust, mantle, inner core and outer core.
Explanation: The crust, which is a main layer is where we live on. Without the crust, we'll be standing on the mantle! The temperate of the crust is 392 Fahrenheit! The crust is 30 km thick. The mantle is the second layer of the earth. It's below the crust and it's hot, dense and semi-solid. It's mostly made of iron, magnesium and silicon. It can reach as hot as 1000 Celsius (1832 Fahrenheit)! It's about 2900 km thick! Anyone who standing on it will melt! The inner core is the 3rd layer. It's below the mantle and made out of liquid iron (molten iron) and nickel. It is about 5,200 Celsius (9392 Fahrenheit). Now that is hot! Hotter than a fire even a heater! The last layer is the outer core. It's made out of liquid iron and nickel, like the inner core. The outer core can be as hot as 5500 Celsius (8132 to 9932 Fahrenheit!)
