In the deep water where there is no sunlight, how do bacteria and plants create
their food?
Answer:
Bacteria and Plants use the process of chemosynthesis to create/make food using chemical reactions.
Explanation:
"Autotrophs that perform chemosynthesis do not use energy from the sun to produce food. Instead, they make food using energy from chemical reactions, often combining hydrogen sulfide or methane with oxygen. ... Bacteria that live in the deep ocean, near hydrothermal vents, also produce food through chemosynthesis."
During replication, enzymes called ____________________ untwist the double helix, separating the two parental strands. The point at which the two chains separate is known as the _______________________.
Answer:
During replication, enzymes called helicases untwist the double helix, separating the two parental strands. The point at which the two chains separate is known as the replication fork.
Explanation:
Replication is the process of multiplication of DNA molecules where, from one molecule, two molecules with the same information as the original can be obtained.. Each new replicated DNA molecule has an original strand and a new strand, so replication is semi-conservative.
For replication to occur, the double strand of DNA must be separated, a process that requires the participation of a group of enzymes called helicases. The helicases are responsible for breaking the hydrogen bonds between the complementary bases of one strand and another.
The DNA strands, when separated, form a zipper-like image, and the point of separation between the two is called the replication fork.
The study of genes is called genetics.
The correct answer is During replication, enzymes called helicases untwist the double helix, separating the two parental strands. The point at which the two chains separate is known as the replication fork.

What is an advantage and disadvantage of using 4.5-7.5 pH paper?
Answer:
The correct answer would be:
Advantage: helps in finding the exact ph value with a narrower range.
Disadvantage: You don't know the exact ph value on a regular scale.
Explanation:
The pH paper is a pH paper with a color indicator that helps in determining the pH value precisely between the 4.5 to 7.5 pH range. It is accurate in comparison to other pH papers such as 0-14 paper. One no need to guess the color between the different colors from various color mixtures as it has a more precise color reading that helps in finding accurate pH value in a narrow range.
On a regular scale, it is not as accurate and one can not find the exact value as it provides a narrow range value between 4.5 to 7.5.
Describe the transportation system in plants .
Answer:
Transportation System in PlantsTransportation Of Materials In PlantsAll living organism need some method of moving substances from one part of the body to other parts of the body. For example, in living organisms food and oxygen are moved in the body to all the cells and waste materials such as carbon dioxide is taken away from them. The system of moving substances in different parts of body is called transport system. In plants, food and water are transported by bundles of tubes present in stem called phloem and xylem. In animals, food, water and respiratory gases (oxygen and carbon dioxide) and other substances are transported by blood.
In plants, transport system is not complicated as in animals. The transport system in plants consists of bundles of tubes in the stem, branches and roots. These tubes are called xylem and phloem. The main function of xylem is to transport water and dissolved minerals from the roots to rest of the plant body. While, the phloem transports the food manufactured in the leaves to all parts of the plant.

All of the offspring produced in a test cross involving a brown rabbit and a white rabbit are brown. The result of this cross is best explained by A. Incomplete dominance B. Codominance C. Crossing over D. Dominance
Answer:
D
Explanation:
The result of the cross is best explained by dominance.
According to Mendel, when the alleles that make up a gene are different and one of the alleles is dominant over the other, the dominant allele would mask the effects of the recessive allele.
In the same vein, when the alternate version of the same trait is dominant, such trait would be expressed over the other version in heterozygous state.
Assuming that the genotype of the brown rabbit is BB and that of the white is bb. When the two rabbits are crossed:
BB x bb
Bb Bb Bb Bb
All the offspring would be heterozygous and brown in color because the brown allele is dominant over the white allele.
Hence, the correct option is D.

How is a light element like helium is formed in stars and how is a heavier element like gold formed by stars? YALL HELP ME WITH THIS PLEASE
1. Elements are not formed in stars. All elements were formed during the Big Bang and no elements have been formed since then.
2. Both light and heavy elements are formed only under very high energy conditions, such as a supernova.
3. Only light elements like helium are formed by stars. They are formed from the fusion of hydrogen nuclei. A hydrogen nucleus is made of a single proton. When protons fuse together, a new atom of helium is formed. Heavier elements like gold cannot be formed under any condition.
4. A light element like helium is formed by the fusion of hydrogen nuclei. A hydrogen nucleus is made of a single proton. When protons fuse together, a new atom of helium is formed. Heavier elements like gold form under very high energy conditions, such as a supernova, when helium atoms combine under enough successive collisions to form very heavy elements.
Answer:
its d
Explanation:
lol im pretty sure im right but i could be wrong
The theory behind the formation of helium and gold is the fusing of hydrogen nuclei results in the formation of a light element like helium. One proton makes up the hydrogen nucleus. New helium atoms are created when protons combine. When helium atoms combine through enough consecutive collisions, as occurs during a supernova, they combine to generate heavier metals like gold. The correct option is 4.
What is fusion?
Fusion is a process in which two nuclei combine to form a large, heavier nucleus. This is a nuclear reaction. Nuclear reactions are of two types, fission, and fusion.
Smaller element or lighter elements like hydrogen and helium are formed by the process of nuclear fission, in which the division of element occur from smaller nuclei.
Heavier elements are formed by the process of nuclear fusion. Where lighter elements joined to create heavier elements.
Thus, the correct option is 4.

In order for protein synthesis to occur, both transcription and translation must occur. Which of the following statements describes the difference between transcription and translation?
In transcription, the genetic code of a DNA molecule is encoded. Translation is the process of converting the DNA code into a code that RNA can use.
In transcription, an amino acid chain is encoded in a DNA molecule. Translation is the process of turning the amino acids into nucleic acids in an RNA molecule.
In transcription, a double helix DNA molecule is split into two separate single strands. Translation is the process of joining each single DNA strand with a single strand of matching RNA.
In transcription, the genetic code of a DNA molecule is transferred to a messenger RNA molecule. Translation is the process of creating an amino acid chain using the encoded messenger RNA.
Answer:
1
Explanation:
In transcription, the genetic code of a DNA molecule is transferred to a messenger RNA molecule. The translation is the process of creating an amino acid chain by using the encoded messenger RNA. So the correct option is D.
What are transcription and translation?The first step in the process of gene expression is called transcription. In this process, the DNA sequence of a gene is copied for the formation of an RNA molecule.
RNA polymerase enzymes link the nucleotides of DNA to form an RNA strand. The DNA strand is the template. For every gene in the genome, transcription is separately controlled.
The translation is the process by which an mRNA molecule encodes for a protein. The process of translation happens with the help of tRNA in the ribosomes.
Translation requires ATP which is produced by the tRNA. The tRNA in the ribosomes supplies energy to RNA for the transcription of proteins The entry of mRNA occurs by the smaller subunit of RNA and the amino acid chain extends from the larger subunit.
Therefore the correct option is D.

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!)
