Answer:
The correct order would be:
b. "Unwind the DNA molecule near the promoter."
d. "Transcribe the complementary RNA strand."
c. "Exit the nucleus to the cytoplasm."
a. "Combine the mRNA strand with a ribosome and a tRNA carrying a methionine."
The given order is according to the central dogma of a cell. According to central dogma DNA is first transcribed into mRNA which is then moved out of nucleus (in eukaryotic cells).
For transcription, the DNA is unwind near the promoter region where transcription factors and RNA polymerase binds the template strand. It then make mRNA which is moved out of the nucleus.
The mRNA then is translated with the help of ribosome and tRNA. The start codon in mRNA usually codes for methionine due to which tRNA carrying methionine recognises the start codon and initiate the process of translation.

Answer:
1- The immune system develops antibodies to the disease so that it cannot make you sick again.
2- Immunization describes the actual changes your body goes through after receiving a vaccine.
3- Immunization is the process whereby a person is made immune or resistant to an infectious disease.
4- Vaccines stimulate the body’s own immune system to protect the person against subsequent disease.
5- Immunity is the capability of multicellular organisms to resist harmful microorganisms from entering their cells.
6- Immunity is the ability of an organism to resist a particular infection or toxin by the action of specific antibodies or sensitized white blood cells.
7- Immunization is the action of making a person or animal immune to infection.
8- Vaccines strengthen the immune system.
• all forests populations
• plants fungi and microbes in the forest
• rushing stream
• rock on which turtles and
frogs sit
please i am really confused and my test is timed so please can someone answer fast :(
Answer:
every squirrel in the forest
all forests populations
plants, fungi and microbes in the forest
Explanation:
In ecology, a community refers to a population of different species of organisms occupying a particular area at a particular time. In other words, community is a group of living organisms of different species interacting with one another in a given habitat.
According to the question, a forest community will contain all plants, animals and microbes in the forest involved in a series of interaction with one another. This includes every squirrel in the forest, all population of organisms in the forest and all plants, fungi and microbes in the forest.
N.B: If the abiotic components are included to the living ones, they will together make up an ECOSYSTEM.
The greenhouse effect is a natural proccess that allows the development of life, it has natural causes. On the other hand, the enhaced greenhouse effect, also know as climate change or global warming, it's reffered to the impact on the climate caused by the overheating of the Earth's surface because of the human activity. Then, option D is correct.
