Compare and contrast a provirus and viral DNA.
A provirus is viral DNA incorporated into the host cell’s DNA.
A provirus is newly replicated viral DNA after injection.
A provirus is the host cell’s DNA that has been destroyed.
A provirus is bacterial DNA incorporated into the viral DNA.
The main difference between 'provirus' and 'viral DNA' is that provirus is viral DNA incorporated into the host cell’s DNA (Option 1)
A provirus can be defined as the genetic material (DNA) of a particular virus which is integrated into the genome of an individual.Since a provirus is already integrated into the host's genome, this sequence can be transmitted from one generation to the next by cell division (either mitosis and meiosis depending on the cell type).For example, the human immunodeficiency virus (HIV) is a retrovirus whose genome is integrated into the host genome (e.g., into host CD4 cells), thereby making it a provirus.Learn more in:

Describe the roles of the soil organisms in the carbon cycle
Carbon cycle is a biogeochemical cycle by which carbon is exchanged among the different components of the Earth.
Carbon cycle along with the Nitrogen cycle and the Water cycle, comprises a sequence of events that are key to make Earth capable of sustaining life.
It describes the movement of carbon as it is recycled and reused throughout the biosphere, as well as long-term processes of carbon sequestration to and release from carbon sinks.
The terrestrial carbon cycle is dominated by the balance between photosynthesis and respiration.
Carbon is transferred from the atmosphere to soil via ‘carbon-fixing’ autotrophic organisms, mainly photosynthesizing plants and also photo- and chemoautotrophic microbes that synthesize atmospheric carbon dioxide (CO2) into organic material.
Fixed carbon is then returned to the atmosphere by a variety of different pathways that account for the respiration of both autotrophic and heterotrophic organisms.
The reverse route includes decomposition of organic material by ‘organic carbon-consuming’ heterotrophic microorganisms that utilize the carbon of either plant, animal or microbial origin as a substrate for metabolism, retaining some carbon in their biomass and releasing the rest as metabolites or as CO2 back to the atmosphere.
What is the role of soil organisms in the Carbon Cycle?Soil Organisms or Microbes are critical in the process of breaking down and transforming dead organic material into forms that can be reused by other organisms and thus the microbial enzyme systems involved are viewed as key ‘engines’ that drive the Earth's biogeochemical cycles.
Soil microbes essentially transfer carbon between environmental compartments to fulfil their fundamental goal: survival through reproduction.
Thus, microbes utilize different organic and inorganic forms of carbon as carbon and energy sources.

What was the name of the orbiting telescope that helped explore space by taking images like this one? THIS IS SICENCE
Answer:
Hubble Space Telescope
Hubble Space Telescope is the name of the orbiting telescope that helped explore space by taking images like this one. Therefore, option (4) is correct.
The Hubble Space Telescope takes photographs like these. Famous astronomy observatory named for Edwin Hubble, launched in 1990. It provides vivid, detailed photographs of celestial objects by orbiting Earth beyond the atmosphere.
Its powerful equipment have revealed faraway galaxies, nebulae, stars, and planets, revolutionising our view of the cosmos. Cosmology advances have revealed the universe's age and expansion pace. Hubble's magnificent images have increased our understanding and sparked public enthusiasm in space exploration and research. Therefore, option (4) is correct.

when energy or heat increases?
A. they disappear
C. their motion decreases
B. they stay the same
D. their motion increases
Answer: it is D : their motion increases
Explanation: because as heat is increased it causes the particles to gain more kinetic energy making them move faster thus increasing their motion and leading to more successful particle collision .

A DNA segment is changed from AATTAG to AAATAG. What type of mutation is this and what is its effect on the genetic variation of a population?
A.
The mutation is a substitution which causes a decrease in the genetic variation of a population.
B.
The mutation is an insertion which causes a decrease in the genetic variation of a population.
C.
The mutation is an insertion which causes an increase in the genetic variation of a population.
D.
The mutation is a substitution which causes an increase in genetic variation of a population.
The mutation from AATTAG to AAATAG is a substitution which causes an increase in genetic variation of a population.
MUTATION:
Mutation refers to any change in the nucleotide sequence of DNA molecule. Mutation can be of different types depending on how it occurs. A substitution mutation is that in which one or more nucleotide base is replaced by another in the sequence. In this question, an original sequence of DNA is given as AATTAG. It was mutated to AAATAG via the replacement of 'T' with 'A'. This means that it is a substitution mutation. However, this mutation will cause an increase in the genetic variation i.e. difference in a population.Learn more at: https://brainly.com/question/21220597?referrer=searchResults
