What process formed this delta?
Select one:
-A:erosion and deposition
-B :condensation and precipitation
-C:rock layer deformation
-D: shifting tectonic plates
Answer:
I think A
Explanation:
because erosion is the washing away of soil
Erosion and deposition are the formed on this delta. Thus, the correct option is A.
What is Erosion and deposition?Erosion is the action of the surface processes such as water flow or wind which removes the soil, rock, or dissolved materials from one location on the Earth's crust and then transports it to another location on the Earth's crust where it is deposited. The erosion is distinct from that of weathering that involves no movement.
Deposition is the laying down of the sediment carried out through the wind, flowing water, the sea or ice. Sediment on the Earth's crust can be transported as pebbles, sand and mud, or as salts dissolved in water. Salts may later be deposited by the organic activity such as sea shells or by evaporation.
Therefore, the correct option is A.

A. RNA polymerase is______ present in a cell, but present in viruses.
B. tRNA is________ present in a cell, but present in viruses.
C. Ribosomes are________ present in a cell, but present in viruses.
D. Genes are_______ present in a cell, but present in viruses.
1. Never
2. Sometimes
3. Always
Answer:
A. RNA polymerase is always present in a cell, but sometimes present in viruses.
B. tRNA is always present in a cell, but Never present in viruses
C. Ribosomes are always present in a cell, but Never present in viruses.
D. Genes are always present in a cell, but always present in viruses..
Explanation:
A. RNA polymerase is always present in a cell, but sometimes present in viruses. RNA polymerase is the enzyme responsible for transcription in eukaryotic cells, it is the enzyme that stimulates transcription, that is, the passage from DNA to RNA. All RNA viruses encode in their genome an RNA-dependent RNA-polymerase (RdRp) that acts as a catalytic subunit, along with other viral and cellular proteins, in the replication of the viral genome. B. tRNA is always present in a cell, but Never present in viruses Transfer RNA is a type of ribonucleic acid that is responsible for transporting amino acids to ribosomes where, according to the sequence specified in a messenger RNA (transcribed, in turn , from DNA), proteins are synthesized. C. Ribosomes are always present in a cell, but Never present in viruses. Ribosomes are responsible for the granular appearance of the cytoplasm of cells. It is the most abundant organelle, several million per cell. Viruses do not have cytoplasm or ribosomes (elements necessary to form a cell), so they cannot multiply on their own and they need to infect the cell of another organism to do so.D. Genes are always present in a cell, but always present in viruses.Genes are the storage units of genetic information, they are fragments / segments of DNA that encode a specific functional product. Viruses are small pieces of RNA (ribonucleic acid) or DNA (deoxyribonucleic acid), many are encapsulated in an envelope made of base of proteins known as capsid, others protect their genetic material with a membrane or envelope derived from the cell they infect and some others also surround their capsid with a cell membrane. RNA viruses bring with them their own genetic information copying machines (eg, RNA polymerase enzyme) or possess genes (genetic information) that produce the proteins required to assemble the copying machines within the cell that they infect, thereby which makes them independent of the cellular machinery and capable of infecting cells that are not actively reproducing.
How is viral reproduction different from the reproduction of single-celled and multicellular
organisms?
A. The virus depends entirely on a host cell to reproduce.
B. The virus relies on nucleic acids, such as DNA, to reproduce.
C. The virus relies on proteins to reproduce.
D. The virus reproduces very rapidly, but in smaller numbers.
Answer:
A. The virus depends entirely on a host cell to reproduce
Viral reproduction different from the reproduction of single-celled and multicellular organisms because the virus depends entirely on a host cell to reproduce. Thus, option A is correct.
What are the difference between single- celled and multicellular organism?The main difference between single- celled and multicellular organism is that single- cellled organisms are made up only single cell on the other hand multicellular organisms are made up of multiple cells.
Cell theory is a scientific theory that's help to learn how living organisms are made up of cells, that's they are the basic structure unit of all organisms, and that all cells from pre-existing cells.
Prokaryotic Cell
Prokaryotic cells are single-celled microorganisms known to be earliest on earth.
Eukaryotic cell
Eukaryotic cells have a nucleus enclosed within the nuclear membrane and form large and complex organism.
Difference between unicellular and multicellular.
The main difference between unicellular organisms and multicellular organisms is that unicellular organism is unspecialized it means all the body function depends upon only on the single cell and in multicellular organism there is specific cells for specific purposes.
Multicellular and unicellular organisms are perform almost all the life running activities and processes such as respiration, reproduction digestion, breathing, and metabolism.
In unicellular organism division of labour is at the organ level on the other hand in multicellular the division of labour at cellular, tissue, organs and organ system level.
Unicellular organism has simple body organization and multicellular organism have complex body organism.
Therefore,viral reproduction different from the reproduction of single-celled and multicellular organisms because the virus depends entirely on a host cell to reproduce. Thus, option A is correct.

ACCGTACTG
Given the following sequence of DNA write the correct sequence of amino acids.
ATAGGCGTA
Answer:
1. ATGGCTATT
2. UGGCAUGAC
3. mRNA: UAU-CCG-CAU, amino acids: tyrosine(tyr)-proline(pro)-histidine(his)
Explanation:
For DNA, the complementary bases are T=A and C=G. This means every time you see one of these letters, the corresponding letter goes with it. For mRNA, the bases are T=A, A=U, C=G. It is the same except now, there should be no "T" in the mRNA sequence. With amino acids, you would first code for the mRNA sequence, every three letters being the amino acid sequence. To find the amino acid, you would look at a codon chart unless your teacher wants you to memorize them. The first three letters of the amino acid are the abbreviation.

In this phase the nuclear ________starts to reform and the DNA de-condenses.
MITOSIS:
This question is describing the process of mitosis, a kind of cell division that results in two genetically identical daughter cells. Mitosis consists of four stages namely: prophase, metaphase, anaphase, and telophase etc. PROPHASE is the first stage of mitosis where DNA condenses down into CHROMOSOMES, and the duplicated separate.METAPHASE is characterized by the lining up of sister chromatids at the CELL PLATE through a push and pull motion as they connect to the microtubule spindle fibers emanating from the CENTROSOME. ANAPHASE is the third stage of mitosis in which duplicated chromosome/sister chromatids are pulled apart into opposite poles. The fourth stage is TELOPHASE where the NUCLEAR MEMBRANE starts to reform and the DNA de-condenses.Learn more at: https://brainly.com/question/3327479?referrer=searchResults
