_________ is when the cell uses the mRNA code to build protein. This process takes place in the _________ with the help of the organelle called the ___________.

Answers

Answer:

1. Translation

2. Cytoplasm

3. Ribosome

Explanation:

Translation is a process whereby the cell uses a mRNA template to produce an amino acid sequence (protein). It is the second stage of gene expression in living organisms.

Translation occurs in the CYTOPLASM of a cell with the help of an organelle called RIBOSOME. The ribosome attaches to the mRNA molecule in the cytoplasm to initiate the process of translation.

what is the end product of the cell cycle

Answers

Answer:

The Meiosis Cell Cycle

Explanation:

Cell cycle is the process if cell division. The end product of cell cycle is two genetically identical daughters cells produced by cell division.

What is cell cycle?

Cell cycle is the process occurring through different stages by which a cell divides to form its daughter cells. Various enzymes have significant roles in cell cycle.

A large number of DNAs in the chromosome of a cell undergo division where, the double stranded DNA separate and and each strand forms two new DNAs.

Therefore, at the end of a cell cycle through proper cell division, two genetically identical daughters cells are produced.

Which pattem of wind flow is most likely to occur during a hot summer season in a coastal location?
А
From land to sea, toward areas of lower air pressure.
B.
From sea to land, toward areas of lower air pressure
С
From land to sea, toward areas of higher air pressure.
D
From sea to land, toward areas of higher air pressure

Answers

Answer:

B.  From sea to land, toward areas of lower air pressure

Explanation:

The pattern of wind flow is most likely to occur from sea to land during a hot summer season in a coastal location due to difference of air pressure. In the summer season when the land is heated, the temperature of the air also increases and hot air rises up, as a result a region of low pressure is created at the surface. The air over the sea moves into this area of low pressure on the land. Hence, the direction of the wind is from the sea to the land during the day in summer season.

_______ 9.  A severe mutation may lead to cell death and may have no effect on the body.

_______ 10.  Most mutation are harmful.

Answer:

FalseFalseFalseFalseTrueTrueFalseTrueTrueFalse

Explanation:  

_False_1.  A molecular group consisting of a sugar molecule, a phosphate group, and a nitrogenous base is a nucleic acid.

Nucleotides: subunits or monomers composed of a sugar molecule, joined with a phosphate group and a nitrogenated base. The chain or sequence of nucleotides composes the polymer. Different nucleotides joined by their extremes compose the nucleic acid: DNA or RNA.  

A molecular group consisting of a sugar molecule, a phosphate group, and a nitrogenous base is a nucleotide.

_False_ 2. In a DNA molecule, a base pair would be composed of adenine and guanine.

In the DNA molecule, Adenine (Purine) always pairs with Timine (Pyrimidine), while Guanine (Purin) pairs with Cytosine. A-T pair is united by 2 hydrogen bonds, and the G-C pair is united by 3 hydrogen bonds.

In a DNA molecule, a base pair would be composed of adenine and timine, or In a DNA molecule, a base pair would be composed of cytosine and guanine.

_False_ 3.  Cytosine and adenine are purines.

Nitrogenated bases that form nucleic acids correspond to purines and pyrimidines. Adenine and guanine derive from purines, while Thymine and Citocine derive from Pyrimidines.

Guanine and adenine are purines.

_False_ 4. During the replication of DNA, bonds are broken between the phosphate groups.

During the replication of DNA, bonds are broken between the hydrogen groups.

_True_ 5.  RNA contains the nitrogenous base uracil.

Instead of Timine, RNA contains uracil that pairs with adenine.  

_True_ 6. There are 20 different amino acids in a cell.

_False_ 7. The coded message carried by messenger RNA is translated into polypeptides at organelles called chloroplasts.  

When mRNA leaves the nucleus, meets a free ribosome in the cytosol. Into this organelle, it starts the protein building. Ribosomes read the mRNA code and begin protein synthesis by adding the correct amino acid using transference RNA.

The coded message carried by messenger RNA is translated into polypeptides at organelles called ribosomes.  

__True__ 8.  The decoding of a messenger RNA message into a polypeptide chain is known as translation

__True__ 9.  A severe mutation may lead to cell death and may have no effect on the body.

_False_ 10.  Most mutation are harmful.

A mutation is a change or alteration in DNI sequences that introduce new variants. Many of these are eliminated, but most of them might succeed and be incorporated into each individual. These mutations are the ones that have been selected by natural selection, leading to evolution.

Most mutation are not harmful

Based on structure, DNA molecules are composed of nucleotides and mutations in DNA are mostly harmful.

What is DNA?

DNA refers to sequences of nucleotides which contain the genetic information of organisms.

Nucleic acids are chains of nucleotides.

Nucleotides are molecular group consisting of a sugar molecule, a phosphate group and a nitrogenous base.

Four nucleotides are present in DNA and they include:

adenine guanimecytidine andthymidine

In a DNA molecule, a base pair would be composed of adenine and guanine is false because adenine bonds to thymine, while guanine bonds to cytidine

Cytosine and adenine are purines is false because cytosine is pyrimidine while adenine is a purine

During the replication of DNA, bonds are broken between the phosphate groups is false because the bonds broken are hydrogen bonds.

RNA contains the nitrogenous base uracil is true as uracil is found in RNA in place of thymine in DNA.

There are 20 different amino acids in a cell is true as these amino acids are found in proteins.

The coded message carried by messenger RNA is translated into polypeptides at organelles called chloroplasts is false because protein synthesis occurs at the ribosomes.

The decoding of a messenger RNA message into a polypeptide chain is known as translation is true.

 A severe mutation may lead to cell death and may have no effect on the body is false because mutations can cause death of organisms.

Most mutation are harmful is true because only free mutations are beneficial.

Answers

Answer:

Fungi kingdom.

Explanation:

Domains are the highest taxonomic category in which living beings can be grouped or divided. There are three domains: archaea, bacteria, and eukarya.

The eukarya domain is composed of the Protist, Fungi, Plantae, and Animalia kingdoms.

Kingdoms include different phyla closely related.

The Fungi kingdom includes yeasts, molds, and mushrooms. All of them are characterized by the same general aspects.

All the members of the kingdom

They grow like hyphae, which are cylindrical uniformed structures that might reach many centimeters in length.Heterotrophic nutrition. The species can not produce their own food, so they decompose organic matter and get the nutrients from there.Reproduction is by spores, which are resistant to adverse environmental conditions.

What is one effect the hydrosphere has on the lithosphere 1).Erosion of rocks 2).Evaporation of water 3).Heating of the core 4).Melting of the core

Answers

Answer:

1).Erosion of rocks

Explanation:

Erosion of rocks has effect of hydrosphere on the lithosphere. When the river and streams passing through a region, the water eroded the rocks that comes in their way with the passage of time as well as the bank of the rivers. The speed of erosion depends on the speed of the flow of rivers because speedy flow of rivers causes fast erosion of rocks so we can say that the erosion is the main effect of hydrosphere on the lithosphere.

A species with genetically identical members would be wholly vulnerable to the same threats and could possibly be wiped out by a single threat.

presence of the placenta (mammals)

Explanation:

Cat and dogs are two species that belong to the group of placental mammals (class Mammalia). Some phenotypic traits that are exclusive of mammal species include, among others, mammary glands, presence of hair or fur, sweat glands, specialized teeth, etc. A phylogenetic tree is a representation of the evolutionary relationships among different groups/taxa. Moreover, cats and dogs represent two different species of placental mammals, which are characterized by the presence of the placenta (an organ that facilitates the exchange of nutrients during gestation). In this case, the remaining two branches in the phylogenetic tree (branches from left to right) separate from more closely related to less closely related taxa that diverged from the same ancestral node.

What are Gametes cells?

Answers

Answer:

I think Gametes are mature male or female reproductive cells that fuse together resulting in a zygote during sexual fertilization. The key difference between somatic cells and gametes depends on the ploidy of the genome. Somatic cells consist of diploid (2n) genome while gametes consist of a haploid (n) genome.

Hope it help you!:)

Answer: Gametes are an organism's reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome. ... In contrast, each egg cell, or ovum, is relatively large and non-motile.

Primary Source #1: Bailey and Kennedy, eds., The American Spirit, Volume I: To 1877, Houghton Mifflin,1998African-born James L. Bradley was a slave who purchased his freedom. In 1834, while a student at the Lane Seminary in Cincinnati, Ohio, he wrote a short account of his life. This is an excerpt from his account. I will begin as far back as I can remember. I think I was between two and three years old when the soul-destroyers tore me from my mothers arms, somewhere in Africa, far back from the sea. They carried me a long distance to a ship; all the way I looked back, and cried. The ship was full of men and women loaded with chains; but I was so small, they let me run about on deck. After many long days, they brought us into Charleston, South Carolina. A slaveholder bought me, and took me up into Pendleton County. I suppose that I staid [stayed] with him about six months. He sold me to a Mr. Bradley, by whose name I have ever since been called. This man was considered a wonderfully kind master; and it is true that I was treated better than most of the slaves I knew. I never suffered for food, and never was flogged with the whip; but oh, my soul! I was tormented with kicks and knocks more than I can tell. My master often knocked me down, when I was young. Once, when I was a boy, about nine years old, he struck me so hard that I fell down and lost my senses. I remained thus some time, and when I came to myself, he told me he thought he had killed me. At another time, he struck me with a currycomb [metal comb used for grooming horses], and sunk the knob into my head. I have said that I had food enough; I wish I could say as much concerning my clothing. But I let that subject alone, because I cannot think of any suitable words to use in telling you.Question: How did James L. Bradley obtain his freedom?
