Answer: A magnet has two poles that is north pole and south pole. From the directional property of the magnet, we know that whenever a magnet is freely suspended, it is always aligned along the north and south direction of the earth.
It can also be identified using a test magnet whose poles are already known. From attraction property of magnet, we know that unlike poles attract with each other and like poles repel each other. Therefore, the pole of unknown magnet that attract to the south pole of the known magnet will be north pole and the other will be south pole.
Thus, by freely suspending the magnet and by using a test magnet, the unmarked poles of the magnet could be easily identified.
Answer:
C: All offspring with at least one R will have red flowers.
Explanation:
Mendel's Law of Dominance states that: “In a cross of parents that are pure for contrasting traits, only one form of the trait will appear in the next generation. Offspring that are hybrid for a trait will have only the dominant trait in the phenotype.”
This simply means that if there exists two contrasting traits (I.e Rr), one of the traits will always suppress the other, thereby expressing itself. R suppresses r, thus making the offspring with big R have red flowers. The trait is called a dominating trait and the suppressed is called recessive trait.
True or False
b. egg cells.
c. stem cells.
d. somatic cells. E. germ cells
Answer:
d. silencer
Explanation:
Based on the information provided within the question it can be said that the deleted sequence most likely functions as a silencer. This term refers to a DNA sequence that is located thousands of base pairs away from the gene that they actually control. In this situation, seeing as the DNA sequence that was found outside the protein coding region actually affected the rate of transcription when it was deleted then it is considered a silencer.
B) low concentration of dissolved oxygen, and farming in the Midwest
C) high concentration of nitric oxides and burning coal to generate electricity in the Northeast.
D) low concentration of dissolved phosphates an Barge traffic on the Mississippi River
B. coded in proteins on the surface membrane.
C. coded in either RNA or DNA.
D. found only in bacteriophages.
2. A lytic infection concludes with the
A. insertion of viral DNA into the host cell’s DNA.
B. production of a prophage.
C. bursting of the host cell.
D. production of messenger RNA.
3. A prophage is made of
A. bacteriophages.
B. carbohydra
A virus's ability to replicate itself is encoded in either DNA or RNA. The creation of biological viruses throughout the infection process in the target host cells is referred to as viral replication and lytic cycle.
Thus, Viruses must initially enter the cell in order to begin viral replication. This packaging allows the virus to spread to new hosts by making copies of itself. The host cell bursting is the correct response.
The host cell bursts at the end of a lytic infection. A lytic cycle is produced when an infected cell and its membrane are destroyed. There are pathogenic bacteriophages, which exist as free-floating molecules, that exclusively use the lytic cycle.
Viral DNA is used to create prophages. Bacteriophage genomes that are integrated and inserted into circular bacterium DNA chromosomes are known as prophages and lytic cycle.
Thus, A virus's ability to replicate itself is encoded in either DNA or RNA. The creation of biological viruses throughout the infection process in the target host cells is referred to as viral replication and lytic cycle.
