An advantage of using natural gas, rather than oil, as a fuel is that natural gas is less of a contributor to global warming because it does not release CO2 when it burns less of a contributor to global warming because it does not release CO2 when it burns A less expensive because most reserves are in the United States less expensive because most reserves are in the United States B more abundant because it is a by-product of photosynthesis more abundant because it is a by-product of photosynthesis C cleaner because it burns more completely cleaner because it burns more completely D safer to store because it is a gas
Answer:
A. less expensive because most reserves are in the United States
Explanation:
Natural gas is less expensive because in the united states there are huge amount of reservoirs present. According to the research, the United States has about 475 trillion cubic feet of proved reserves and 2,392 trillion cubic feet of unproved reserves of dry natural gas. It is a clean source of energy comparatively coal and fossil fuel because it produces less amount of carbondioxide and other pollutants in the atmosphere so that's why the natural gas is less expensive and prefers in usage.

Use your understanding of prevention and treatment of viruses to answer the questions below.
A
is a substance containing incomplete portions of a virus that produce an immune response when injected into the body.
I'm a bit confused about this question. But I will try my best to answer. :)
To prevent a certain virus, or increase someone's immunity towards a virus, doctors give patients a shot/vaccine. For example, people get a flu shot yearly to help prevent them from getting the flu. The shot contains a small portion of the flu itself. The flu remains dormant until the body decides to activate it or fight it off. This also helps the body become more immune to the virus/sickness and fight it off easier.
I hope this helps! :)
A hapten is a substance containing incomplete portions of a virus that produce an immune response when injected into the body.
What is the Immune response?The immune response may be defined as the type of reaction that occurs in response to specific antigens or foreign agents. Such types of responses defend the organism against foreign invaders.
A hapten is essentially an incomplete antigenic particle. Such small substances or molecules only elicit an immune response when attached to a carrier known as proteins.
Carrier molecules typically do not elicit an immune response by themselves.
Therefore, it is well described above.

Where can you find the DNA in a eukaryotic cell? Where can you find the DNA in a prokaryotic cell?
Answer:
first question:The nucleus is particularly important among eukaryotic organelles because it is the location of a cell's DNA. Two other critical organelles are mitochondria and chloroplasts, which play important roles in energy conversion and are thought to have their evolutionary origins as simple single-celled organisms
:second question: The DNA in prokaryotes is contained in a central area of the cell called the nucleoid, which is not surrounded by a nuclear membrane.

why would you expect Greenland to have a higher albedo than its surrounding areas?
The albedo of the ice sheet is high in winter when much of Greenland is covered by fresh snow.
Greenland is filled with ice and has a higher reflectance rate as in winters it's covered with fresh snow.
Where is Greenland?The greenland is an island nation and lies between the arctic and Atlantic ocean. Has an area of 2.166 million square km and is among the largest island in the world.
It has the third-largest area in North America after Canada, The lowest temperature is recorded in Greenland in the northern hemispheres. Greenland is Greenland snow is thick and fresh in winter this creates a higher albedo.

A high population of greater prairie chickens once inhabited the prairies of Illinois. The conversion of the prairies into agricultural land caused the chickens to lose their habitat. Studies have concluded that this change greatly reduced the greater prairie chicken population. The habitat loss also resulted in a decrease in the population’s genetic variation.
Which change in the gene pool occurred in the greater prairie chicken population?
gene mutation
gene flow
genetic drift
genetic resistance
The answer is C. genetic drift
Genetic drift affects the population size and decreases genetic variability by setting some alleles and losing others. Option C. The exposed example is a case of genetic drift - bottleneck effect -.
What is genetic drift?
Genetic drift is an evolutive force. It refers to the random change that occurs in the allelic frequency of a population through generations.
The magnitude of this change is inversely related to the size of the original population.
These changes produced by genetic drift accumulate in time. Eventually, some alleles get lost, while some others might set. Genetic variation in the population decrease.
Genetic drift affects a population and reduces its size dramatically due to
a disaster or pressure ⇒ bottleneck effectthe population split ⇒ founder effect.The exposed example is a case of the bottleneck effect. The conversion of the prairies into agricultural land and the consequent habitat loss is the pressure acting on this prairie chickens population. The population decreases in size and decreases its genetic variation.

Pulmonary circulation pumps deoxygenated blood through the pulmonary artery. This artery divides above the heart into two branches, to the right and left lungs, where the arteries further subdivide into smaller and smaller branches until the capillaries in the pulmonary air sacs (alveoli) are reached.

natural selection

genetic variation
Answer:
Genetic variation
Explanation:
It could lead to natural selection, but natural selection isn't the cause. Many years down the road you could see a particular variation having a higher population, which is the result of natural selection/survival of the fittest via better camouflaging from predators.

How many chromosomes are in the gametes of an organism that has 88 chromosomes in its diploid cells?
Answer:
It is a worldwide universal truth that all living organisms produce gametes which comprised of a quasi or half number of Chromosomes in contrast to their inventive number of chromosome. Generally, in simple words, the gametes ploidy will be going halves on than the ploidy of the organism.
Ovum is the ‘female’ gamete which is truly the new-fangled individual of the species. It is basically, the solo cell in which disunion progression take place and baby will make. The ovum being single cell comprised of, ample chromosomes set. In humans Ovum chromosomes is 22 and one more X chromosome overall, making it 23 chromosomes. �The ovum required chromosomal set to become doubled and to the concert itself in the baby by development and cell division. This can be done once after when comprehensive and identical chromosomes of sperm combined with ovum after mating. Therefore, humans body cells comprised of 46 chromosomes.

Is it possible to have a knockout mutant plant that shows no visible phenotype that is different from the wild-type plant?
Answer:
Molecular genetic approaches to the study of plant metabolism can be traced back to the isolation of the first cDNA encoding a plant enzyme (Bedbrook et al., 1980), the use of the Agrobacterium Ti plasmid to introduce foreign DNA into plant cells (Hernalsteens et al., 1980) and the establishment of routine plant transformation systems (Bevan, 1984; Horsch et al., 1985). It became possible to express foreign genes in plants and potentially to overexpress plant genes using cDNAs linked to strong promoters, with the aim of modifying metabolism. However, the discovery of the antisense phenomenon of plant gene silencing (van der Krol et al., 1988; Smith et al., 1988), and subsequently co‐suppression (Napoli et al., 1990; van der Krol et al., 1990), provided the most powerful and widely‐used methods for investigating the roles of specific enzymes in metabolism and plant growth. The antisense or co‐supression of gene expression, collectively known as post‐transcriptional gene silencing (PTGS), has been particularly versatile and powerful in studies of plant metabolism. With such molecular tools in place, plant metabolism became accessible to investigation and manipulation through genetic modification and dramatic progress was made in subsequent years (Stitt and Sonnewald, 1995; Herbers and Sonnewald, 1996), particularly in studies of solanaceous species (Frommer and Sonnewald, 1995).
