III. Ribosome reaches a STOP codon and detaches from the mRNA
IV. Each tRNA adds an Amino Acid to the chain as the Ribosome moves along the mRNA
V. Complimentary mRNA strand is made from DNA template

Answers

Answer:

I. tRNA anticodon bonds to mRNA codon

II. Ribosome bonds to mRNA strand

III. Ribosome reaches a STOP codon and detaches from the mRNA

IV. Each tRNA adds an Amino Acid to the chain as the Ribosome moves along the mRNA

Explanation:

Translation is the second process of gene expression in which a protein molecule is synthesized from the information in a mRNA strand. Translation occurs in the RIBOSOME (an organnelle for protein synthesis made up of ribosomal RNA (rRNA) and proteins). The process of translation occurs in three stages viz: Initiation, Elongation and Termination.

Initiation occurs when the ribosome binds to the mRNA strand in the cytoplasm. The mRNA sequence is then read in a group of three nucleotides called CODON by the ANTICODON of a transfer RNA (tRNA). The basis of reading is the complementary base pairing rule i.e. A-U, G-C. Options I and II describes this stage.

In the elongation stage, the tRNA carries an amino acid corresponding to what it reads in the mRNA codon to the growing polypeptide chain. The amino acids bonds to one another via a peptide bond. As each codon is being read, the mRNA gradually moves over the means sequence. Option IV describes this stage.

Elongation stage continues until any of the stop codons (UAA, UAG, and UGA) are finally encountered by the trans in the ribosome. Since, there are no corresponding anticodons that can read the stop codons, they signal the termination of the translation process. The ribosome then detaches from the mRNA sequence. Option III describes this stage.

Note, option V describes TRANSCRIPTION not TRANSLATION.

many endangered species are predators that belong to the higher trophic levels. Which is the process that primarily affects animals at the highest trophic levels?

Answers

Answer:

Top predators at the highest trophic levels eat lower-level predators and herbivores

Explanation:

A trophic level is defined as one group of organisms in the ecosystem occupying the same level in the food chain, which is composed of different levels (primary, secondary and higher levels). Top predators at the higher levels maintain the trophic balance by eating other species that eat on primary producers/consumers, thereby favoring the homeostasis of the ecosystem.

Membrane-bounded vesicles that contain enzymes for oxidizing small organic molecules with the formation of hydrogen peroxide are Group of answer choices

Answers

Answer:

peroxisomes

Explanation:

The peroxisomes represent one of the organelles of the cell. They are usually small and characterized by membrane-bound vesicles that contain oxidative enzymes.

The enzymes in peroxisomes are involved in the oxidation of organic molecules - a process that leads to the formation of hydrogen peroxide. The later is further converted to water and oxygen by the constituent catalase enzyme of the peroxisomes. Fatty acids are also oxidized in peroxisomes but instead of hydrogen peroxide, acetyl groups that are utilized in other biosynthetic reactions are produced.

he most common source of osteomyelitis is an infection that migrates via the bloodstream. direct invasion from a fracture. surgical contamination. a joint prosthesis.

Answers

The correct answer is A. An infection that migrates via the bloodstream

Explanation:

Osteomyelitis is a serious condition, in which an infection develops in bones. This causes symptoms such as pain, inflammation, and can lead to the spread of the infection to other tissues or bone necrosis if it is not treated. In terms of causes, this condition develops when the bone is exposed to bacteria or similar that causes the infection, this can occur during surgeries or fractures. However, the most common source of infection is via bloodstream this means the bacteria or germ is in the blood and it enters the bone through the bloodstream. Also, once the bacteria or germ is in the bone it causes the infection.

Acidification of the stomach uses all of the following types of transport EXCEPT: A. channels. B. pumps. C. antiporters. AND. symporters. E. All of these are used by parietal cells.

Answers

Answer: Option E.

All of these are used by parietal cells.

Explanation:

Parietal cells are found in the stomach and they produced gastric acid(Hcl)..

HCl is produced when water mixed with carbondioxide in the parietal cell to produced carbonic acid which is catalyses by carbonic anhydrase. The carbonic acid then dissociates into hydrogen ion and carbonate ion.

Parietal cell produce HCl due to histamine (via H2 receptors), acetylcholine (M3 receptors) and gastrin (gastrin receptors).

Therefore it uses channels, pumps, antiporter.

This question is incomplete; here is the complete question:

All of the following are examples of organic matter soil except

A. Decaying plants

B. Bacteria

C. Fungi

D. Water

The answer to this question is D. Water

Explanation:

Organic matter derives from living beings, due to this, organic matter is considered as a biological product. In this context, materials such as decaying plants are organic matter because they derive from living organisms and contain biological molecules (most contain carbon). This category does not apply to water, which is composed of hydrogen and oxygen and does not derive from living beings. Thus, the one that is not organic matter is water.

DNA C. tRNA D. Thymine E. Uracil F. rRNA G. Ribosome

Answers

Answer:

A molecule containing genetic information - DNA

RNA base that pairs with adenine - Uracil

Carries amino acid to ribosomes - tRNA

The site of protein synthesis - Ribosome

DNA base that pairs with adenine - Thymine

Carries the genetic code to ribosomes - mRNA

Explanation:

DNA is the molecule that is responsible for conveying genetic information in living organisms. It is made up of deoxyribose sugar, a phosphate group, and purine/pyrimidine bases. The purine bases consist of adenine and guanine while the pyrimidine bases include thymine and cytosine. As a matter of rule in the DNA, Adenine base always pairs with Thymine base while the Cytosine base always pairs with Guanine base.

RNA on the other hand is single-stranded unlike the double strands of DNA. It has all the nucleotide bases present in DNA except that the Thymine bases are usually replaced with Uracil.

There are three types of RNA:

the messenger RNA that is responsible for carrying genetic code from DNA to the ribosome for translation purpose, the transfer RNA responsible for carrying amino acids to ribosome during the translation process; and the ribosomal RNA which forms an integral part of the subunits of the ribosome itself.

Design a controlled experiment to test the effect of water temperature on goldfish. be sure to include your hypothesis, independent variable, dependent variable as well as experimental group and control group.

Answers

Answer:

In this experiment, indepedent variable will be temperature and dependent variable will be the respiratory rate of goldfish. Temperature affects the respiratory rate of goldfish, as it's respiratory rate decreases with decrease in temperature of water, the experiment is as follows:

Take two glass containers filled with water A and B and put one goldfish in each container.Measure the temperature of the water using a thermometer.Count mouth movement of both the fishes in certain time.Now put some ice in container B that will decrease the temperature of water and measure the temperature again.Now count the mouth movement of both the fishes for the same time it was counted earlier.

The result will be that respiratory rate of goldfish decreases with the decrease in temperature in container B in comparison to container A goldfish.

An experiment meant to determine the cause of an effect, the effect is the independent variable, while the cause is the dependent variable

A controlled experiment to test the effect of water temperature on goldfish is designed as follows:

The experimental group are: The gold fish in a glass Jar X filled with fresh water and with the lid left open (the treatment of temperature reduction is applied to the experimental group)

The control group are: A second gold fish (selected at random) of the same size, in another glass jar Y filled to the same level with fresh water collected from the same source of the first gold fish

Independent variable: The independent variable is the temperature of the water which will be varied by placing ice cube gradually into the glass jar B

Dependent variable: The number times the gold fish gulp air by rising to the surface, and or the number of time goldfish opens its mouth, which indicates that the goldfish is breathing

The hypothesis: The breath rate of goldfish decreases with decrease in temperature because the goldfish metabolic rate decreases and the water holds more dissolved air and therefore oxygen at a reduced temperature

The Experiment Design:

The experiment is conducted by measuring the initial temperature and breathing rate of both fishes

The temperature of the fresh water in jar X is decreased gradually by adding ice cubes and recording the temperature and breathing rate of the goldfish

A similar experiment from an online source (Maryland School improvement website) the following results where obtained

[tex]\begin{array}{|c|cc|} \underline {Breathing \ rate}&&\underline {Water \ Temperature } \\&&\\ (Dependent \ Variable)&&(Independent \ Variable)\ \\&&\\103&&78.8 ^{\circ}F\\78&&68^{\circ}F\\55&&57.2^{\circ}F\\28&&46.4^{\circ}F\\4&&35.6^{\circ}F\end{array}\right][/tex]

From the experiment, it can be seen that the in the experimental group dependent variable, which is the breathing rate of the goldfish reduces as the temperature which is the dependent variable is reduced
