Answer
(From top left to the bottom) Neisseria gonorrhoeae, Herpes Simplex virus, Human papillomavirus (HPV)
(From top right to the bottom) Theponema pallidum, Chlamydia trachomalis, Candida albicans
Explanation:
Neisseria gonorrhoeae: infected individuals may experience pain when urinating or during sexual intercourse. It may be accompanied by unusual discharge (white, creamy or green) from the vagina or penis
.
Herpes Simplex virus: causes painful sores around the lips and genitals. These sores are contagious
.
Human papillomavirus (HPV): a viral STI, it appears as warts on the male and female genitals when a person is infected. These look like a cluster of pimples
Theponema pallidum: also known as syphilis, it is characterized by painless sores around the mouth or genitals. The sores may later develop into rashes.
Chlamydia trachomalis: may not have any symptoms but if there are any, they include discharge from the vagina or penis
.
Candida albicans: is a fungal infection that produces vaginal discharge that looks like cottage cheese
.
Transcription is the process by which RNA (nucleic acid that is responsible for transferring genetic information from DNA ) is synthesized from the genetic information contained in the coding regions of DNA. Therefore, a copy of complementary RNA and antiparallel to the DNA sequence that was transcribed is obtained. Normally organism synthesize RNA by a reaction catalyzed by RNA polymerases (they are enzymes that are involved in the process of DNA replication).
Transcription occurs in three steps: initiation, elongation and termination.
Initiation: Is the beginning of transcription. It occurs when the RNA polymerase enzyme binds to a region of a gene called a promoter. This tells the DNA to unwind so that enzyme can 'read' the bases in one of the strands of DNA. The enzyme is now ready to create a strand of mRNA (it is a single stranded RNA molecule, complementary to one of the DNA strands of a gene) with a complementary base of bases.
Elongation: Is the addition of nucleotides to the mRNA strand. The RNA polymerase reads the unwound strand of DNA and builds the mRNA molecule, using complementary base pairs. THere is a brief moment during this process when the new RNA molecule is bound to the unwound DNA. During this process, an adenine in the DNA binds to an uracil in the RNA.
Termination: Is the term of transcription and occurs when RNA polymerase crosses a termination sequence in the gene. The mRNA strand is complete and separated from the DNA.
The two DNA strands unwind from one another during semi-conservative replication, and each serves as a template for the synthesis of a new, complementary strand. Two DNA molecules are produced as a result, each with one original and one new strand.
The act of duplication is referred to as replication. DNA replication is the first step in inheritance in molecular biology. The central dogma explains how the DNA replicates itself, codes for the RNA during transcription, and then codes for the proteins during translation.
On several sources of replication along the DNA template strand, DNA replication takes place (antinsense strand). One original strand and one freshly synthesized strand are included in every copy. Although it should be guaranteed that both copies are identical, Each strand of the double helix would act as a template for the manufacture of a new strand, according to the structure of DNA (which was discovered by James D. Watson and Francis Crick in 1953). The process by which freshly created strands united with template strands to create two double helix DNA molecules was unknown.

They are related because a modern bird has scales on its feet..
Answer:
True
Explanation:
Fixation converts nitrogen in the atmosphere into forms that plants can absorb through their root systems. A small amount of nitrogen can be fixed when lightning provides the energy needed for N
