A researcher examined the response of dandelions to herbivory by rabbits. She finds that in a greenhouse with no rabbits, there is variation in the number of seeds produced by different dandelion plants. She then mimics herbivory by rabbits and finds that dandelions that have been "eaten" by rabbits produce more seeds. From this she concludes:___________

a. The number of seeds of a dandelion is a genetically variable trait
b. Dandelion seed number is a constitutive defensive response to rabbit herbivory
c. Rabbits cause a decline in the number of dandelion seeds
d. Rabbits alter the genetics of dandelions as they feed on them

Answers

Answer 1

Answer:

b.

Explanation:

Based on the information provided within the question it can be said that from this info the researcher can conclude that Dandelion seed number is a constitutive defensive response to rabbit herbivory. This is mainly due to the fact that Dandelions that have been eaten by the rabbits have produced more seeds, meaning that the Dandelions defense mechanism produces more seeds when attacked in order to prevent the flower's extinction.

Rarely, the conjugation of Hfr and F− cells produces two Hfr cells. Explain how this event takes place.

Answers

Answer:

"F" on account of E.coli show the fertility factor. Cells possessing this factor (called donors) hold the ability to move the hereditary material over the strains by a procedure called conjugation. F-factor exists as a free element (cell is called episome) or integrated into bacterial chromosome (cell is called Hfr-High frequency recombinant). Cells with no F factor are recipients.

In a Conjugation between a F+ and F-cell just F factor from F+ cell gets moved o produce two F+ cells. But during a Hfr and F-conjugation as the F factor is incorporated into the chromosome and by the intrinsic idea of F factor to get moved the Hfr cells attempt to move their whole genetic material across and there are two outcomes wherein one case there is a fragmented exchange of hereditary material and the recipient cell remain F-and when there is a finished exchange of hereditary material the cell becomes Hfr yet this is uncommon as the time taken for the total exchange of hereditary material is excessively long for the cells to remain contact.

Why is the word "translation" used for protein production? Protein production is the process of:________.

Answers

Answer:

Answered below

Explanation:

Translation is the actual process of protein synthesis and it occurs in the cytoplasmic ribosomes. Protein production or protein synthesis is the process in which cells make proteins. This process occurs in two stages called transcription and translation.

Transcription involves the transfer of genetic information in the deoxyribonucleic acid to the messenger ribonucleic acid in the nucleus through the process of initiation, elongation and termination. The messenger ribonucleic acid is processed and carries the information to a ribosome in the cytoplasm where protein production takes place through translation.

During translation, the instructions in the messenger ribonucleic acid are read and transfer ribonucleic acids ensure the correct sequencing of amino acids in the ribosomes. The rRNA is involved in the bonding of the base pairs to produce a polypeptide chain which is a unit of a finished protein.

Answer:

The word translation is use for protein production because it is the process of translating RNA sequence of bases.and thereby producing sequence of encoded amino acids from the RNA

sequence which is a consist of polypeptide chain during protein synthesis.

Protein production is the process of synthesising protein.

Explanation:

Translation is a process that occur in the RIBOSOMES or endoplasmic recticulum after transcription of RNA and it is the process where genetic code in the messenger RNA is decided or translated to a sequence of amino acid.

Protein synthesis is processs by which cells produce protein which occur in the RIBOSOMES.

Protein synthesis occurs in two stages which are Transcription and translation.

Transcription is the process whereby genetic instructions or materials in DNA are transmitted to messenger RNA in the nucleus.

It involves initiation, enlongation and termination.

Translation is a process that occur in the RIBOSOMES or endoplasmic recticulum after transcription of RNA and it is the process where genetic code in the messenger RNA is decided or translated to a sequence of amino acid.

Explanation:

Dams are used to store or hold water for hydroelectric power plants. This stored water which has gravitational energy is a form of potential energy.

When the water is left to fall and run fast through the turbine, the gravitational energy is transformed into kinetic energy which makes the turbine to spin.

As the turbine spins, kinetic energy that is produced also powers the shaft of the engine in the electric generator, which produces electricuty.

Kinetic energy is transformed to electric energy and transmitted along powerlines.

John complains of severe pain in the region of his left cheek which seems to increase when he chews on his food. A tense swelling is seen just anterior to his left ear. Which of the following structures do you think is the most likely cause of the problem?
1) submandibular salivary gland2) lingual tonsil3) palatine tonsil4) parotid salivary gland5) sublingual salivary gland

Answers

Answer:

Parotid salivary gland.

Explanation:

John's parotid salivary gland is the major cause of the problem

Parotid salivary gland is the largest of the salivary gland. Parotid salivary gland is found in the mouth, the upper part of the cheek and part of the ear.

This gland help to chew and empty saliva into the mouth.

A viral infection like flu, mumps can cause swelling of the parotid salivary gland.

Other symptoms include ;

Tender , lump cheeks.

Swollen cheeks

Difficulty in opening the mouth and swallowing food.

Pain in the left ear

Fever , chills and general weakness and so on.

Treatment of this depend on the type of infection, drinking hot water with lemon juice can help can help stimulate saliva.

Answer:

parotid salivary gland-parotitis.

Explanation:

This is located in front of and just below  each ear.When the duct which drains this gland it blocked,drainage of saliva is prevented, and therefore lack of drainage leads to pain.

its inflammation is due primarily to bacterial infection,among other factors which are HIV,diabetes,etc.

Antibiotic intake is the most effective way of treatment.

In addition,the treatment is based on saliva stimulation to unblock the drainage. Therefore lemon intake either as raw or with water is ideal way.
