Answer 1

Answer: #5. The Rabbitt population is followed by an increase in the lynx because the rabbit is the lynxs food when there are more rabbits more lynx will come #7.when the rabbits population decreases the lynxs decreases because the rabbit is the lynxs food source and when their is no food the starve this is called famine #6 whenever the population of the lynx rises the rabbits decreases because it is being eaten by the lynx #8 Whenever the lynx population drops the rabbits rise because the rabbit has less chance of being preyed upon

Today, it is Moore's turn to measure the earthworms. For theworm above, Moore records a length of 6.0 cm. Explain whether Moore's recording is accurate and why.A)The earthworm length is shorter than 6.0 cm because the worm is curved.B)The earthworm length is shorter than 6.0 cm because Moore used theincorrect units.C)The earthworm length is longer than 6.0 cm because the worm needs tobe straightened.D)The earthworm measurement is accurate because Moore subtracted thebeginning and ending points from the ruler.

Answers

RNA nucleotides form complimentary base pairs with DNA bases. Hydrogen and sugar-phosphate bonds form and the mRNA is synthesized.

Explanation:

The process of mRNA formed by DNA is called transcription. The genes coding for the protein is present on DNA as a nitrogenous base or nucleotides.

Transcription takes place inside the nucleus with the assistance of major enzyme RNA polymerase. In transcription 5'to3' single strand of RNA is synthesized which is complementary to the 3'to5' strand of DNA. The sequence of DNA has promoter sites which will be recognized and DNA will unzip to form transcription bubble. Several transcription factors and enzyme will be required to synthesize mRNA.

This mRNA after some modification would become primary transcript and pass on to the cytoplasm where protein synthesis will take place.

What is a fine-grained material that has been transported and deposited by the wind ? A. Loess

B. Sandblast

C. Slip face

D. Sand dunes

Answers

Answer: Loess is the fine grained material that has been transported and deposited by the wind.The answer isA.

Explanation:

Since the wind can carry these types of material (find grained) father than sand, and also higher up, they are generally found very far from their original place of origin.

Loess is no larger than 50 micrometers in size. It is coarse in texture like clay, but finer than a grain of salt.

Many bacteria are able to pass small pieces of the hereditary information on their DNA from one bacterial cell to another. This can sometimes result in an increase in the number of drug-resistant bacteria. What name is given to the process by which one bacteria transfers DNA to another? A) sporolysis B) conjugation C) gametic transfer D) haploid translocation

Answers

Answer:

The process in which one bacteria transfers DNA to another is called conjugation.

Explanation:

Conjugation is the process of transferring genetic material from one bacteria to another through direct cell contact. In the process of conjugation one bacteria acts as donor and transfer the DNA to a recipient. There is a specific DNA sequence present in Donor's DNA called fertility factor (F factor). F factor helps in the formation of pillus which is the site of genetic material transfer.
