Gene expression in prokaryotes is regulated at which stage?
A. Translation
B. Transcription
C. Post-transcriptional modification
Answer:
Transcription
Explanation:
This occurs in three steps itself: initiation, elongation, and termination
Initiation (beginning)
- RNA polymers bind to a promoter on a gene
- DNA then unwinds to be "read" by an enzyme
- DNA now ready to make mRNA strand
Elongation (Second step)
- nucleotides are added to mRNA strand
- mRNA molecule is built after RNA polymers reads the DNA that unwound
- adenine (A) in DNA connects to a uracil (U) of RNA while connected to each other
Termination (End)
- RNA will cross a stop sequence in the gene (termination)
- mRNA done and disconnects or detaches from DNA

Answer: D
Explanation:
Years after the lava from an erupting volcano destroyed an area, lichens started to grow in that area. These were gradually replaced by grasses, shrubs, conifers, and finally, by
a deciduous forest. If the deciduous forest remains unchanged, it will be referred to as
1) a pioneer community
2)a stable climax community
3)a food chain
4)the biosphere
Answer:
2)a stable climax community
Explanation:
It is a stable climax community because the community went through various degrees of succession starting from the pioneer species which comprised of lichens. Successive species such as grass, Shrubs and conifers were also present till it reached a climax with zero degree of succession.
The deciduous forest remaining unchanged is referred to as a stable climax community.
Answer:
2) a stable climax community
Explanation:
This question portrays ECOLOGICAL SUCCESSION, which is a series of gradual changes that occurs to the community of an ecosystem. According to the question, a natural occurrence (lava from an erupting volcano) destroyed an area, which was later recolonized by LICHENS, regarded as the PIONEER species.
The lichens were later replaced by grasses, shrubs and conifers until the area later became a deciduous forest. If the deciduous forest remains unchanged for a long period of time, it will be the final stage of the succession and hence will be regarded as a STABLE CLIMAX COMMUNITY.
It is called a stable climax community because the organisms in the deciduous forest have adapted to the environment and succession has stopped occurring.
Compare and contrast the elevated temperature of someone who is exercising vigorously and someone who has an infection.
Answer: seen below
Explanation:
In vigorous exercise, your brain and body do everything they can to cool you off by increase the flow of blood to the skin where it can cool down with the aid of sweating , while in someone who has an infection they push the temperature inside your body to extreme levels by strengthening your immune system resistance to the infection, the immune system deliberately raises your body temperature as part of its strategy to kill the infection attacking you.

b. How might more species diversity within a community make it more stable, even if it lacks genetic
variation? Consider species interactions and the flow of matter and energy in your answer. (2 points)
Increased species diversity within a community fosters stability through complementary interactions, niche partitioning, and trophic cascades, promoting resilience against disturbances.
When a community harbors more diverse species, each occupies a unique ecological niche, reducing competition for resources and allowing for niche partitioning, where species coexist by utilizing different resources. This enhances resource use efficiency and reduces the risk of resource depletion or single-species dominance.
Additionally, certain species may engage in mutualistic relationships, benefiting each other and promoting overall community resilience. Trophic cascades can also contribute to stability, where changes in one species' abundance influence the entire food web. In the absence of genetic variation, a diverse community can still respond better to disturbances due to the complexity of interactions, ensuring efficient matter and energy flow, and maintaining ecosystem stability.

How is smallpox different when it comes to making a vaccine?
Answer:
"The smallpox vaccine does not contain smallpox virus and cannot spread or cause smallpox. However, the vaccine does contain another virus called vaccinia which is live in the vaccine. Because the virus is alive, it can spread to other parts of the body or to other people from the vaccine site."

Name three adaptations that helped plants survive on land, and describe how each of them helped.
Answer:
Three adaptations that helped plants survive on land were thin leaves, vascular systems, and stomata.
Explanation:
Yes, this is superrrr late, but I hope this helps somebody!
Have a nice day :)
Plants have evolved several adaptations to life on land, including embryo retention, a cuticle, stomata, and vascular tissue.
What are the 3 plant adaptations?
There are three types of adaptation - structural adaptation, behavioral adaptation, and physiological adaptation. A structural adaptation is a physical feature that an organism has evolved in order to survive. In plants, this could include the evolution of waxy leaves or different root structures.
How did plants adapt to land?
Land plants evolved traits that made it possible to colonize land and survive out of water. Adaptations to life on land include vascular tissues, roots, leaves, waxy cuticles, and a tough outer layer that protects the spores. Land plants include nonvascular plants and vascular plants.
