Answers
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 .

Explain mutations and how they can cause genetic disease
Answers
A mutation is a change in a DNA sequence. Mutations can result from DNA copying mistakes made during cell division, exposure to ionizing radiation, exposure to chemicals
called mutagens, or infection by viruses. Germ line mutations occur in the eggs and sperm and can be passed on to offspring, while somatic mutations occur in body cells and are not passed on.
Mutation has been the source of many Hollywood movies, but it's really a simple process of a mistake made in a DNA sequence as it's being copied. Some of that's just the background noise that DNA copying is not perfect, and we should be glad of that or evolution couldn't operate. But mutation can also be induced by things like radiation or carcinogens in a way that can increase the risk of cancers or birth defects. But it's pretty simple; it's basically an induced misspelling of the DNA sequence.
That's a mutation.
When a variant alters a protein that plays a critical role in the body, it can disrupt normal development or cause a health condition. A condition caused by variants in one or more genes is called a genetic disorder. In some cases, gene variants are so severe that they prevent an embryo from surviving until birth.

Describe the roles of the soil organisms in the carbon cycle
Answers
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.

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.
Answers
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

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.
Answers
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:
