Crime-scene work often involves obtaining a DNA sample from a drop of blood to help identify persons who may have been involved. Frequently, the size of the DNA sample is extremely small, too small for easy analysis. Which of the following laboratory procedures could criminologists use to amplify the amount of DNA present?
A: Cloning and gel electrophoresis
B: Cloning and polymerase chain reaction (PCR)
C: DNA splicing and polymerase chain reaction (PCR)
D: Vector amplification and DNA splicing
Amplification of DNA is a very useful tool in the study of the human genome. DNA amplification ensures the production of multiple copies of the needed segment.
Criminologists can use Cloning and PCR to amplify the amount of DNA present...
Cloning involves creating identical copies of a particular DNA segment in study. Then amplification of the DNA using polymerase chain reaction will aid in amplifying and producing thousands of these copies of short targeted segments in minutes. This tool is very useful in ensuring the multiplication of that particular targeted sequence for analysis.Learn more about PCR: https://brainly.com/question/20757028
The world population has surpassed 7 billion and is continuing to increase dramatically. Select the factor that has demonstrated an
inverse relationship to population growth.
es )
A)
deforestation
B)
violent political conflict
spread of communicable diseases
D)
biodiversity of plant and animal species
Answer:
D
Explanation:
As population grows all the above factors increase expect the biodiversity of animal and plant species.
On a basic level, it is obvious that population increase and per capita income growth are related. Per capita income is simply total income divided by the population. Thus, option D is correct.
What inverse relationship to population growth?When attempting to forecast changes in population size, demographers frequently focus on four essential criteria.
The population's starting age profile (whether it is relatively young or old to begin with), migration, and fertility rates (death rates; life expectancy).
Depending on particular environmental factors, two different patterns of population expansion may manifest: In a perfect, limitless environment, an exponential growth pattern (J curve) manifests itself.
The development of a logistic growth pattern (S curve) occurs when external forces reduce the pace of growth.
Therefore, The gap between the growth rates of income and population is roughly equivalent to the growth rate of per capita income.

The G. rabbit is the only primary consumer seen.
Trophic Levels in Food ChainThe food chain is made up of three main groups of living beings:
ProducersConsumers and Decomposers.Each of them represents a trophic level of energy flow transmitted through food. The first trophic level is formed by the producers and the last one is the decomposers.
Primary ConsumersAre all organisms that feed directly on Producers. In this case, they are usually herbivorous or omnivorous animals, as they consume plants.
With this information, we can conclude that in the alternatives, g. rabbit is the only alternative corresponding to a primary consumer.

During photosynthesis, plants produce _____________ and oxygen from the _____________________________ of solar energy, water, and carbon dioxide
Answer:
During photosynthesis, plants produce glucose from simple inorganic molecules - carbon dioxide and water - using light.
Explanation:
Most life on Earth depends on photosynthesis.The process is carried out by plants, algae, and some types of bacteria, which capture energy from sunlight to produce oxygen (O2) and chemical energy stored in glucose (a sugar). Herbivores then obtain this energy by eating plants, and carnivores obtain it by eating herbivores.
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.

____________ diffuses out of the alveoli and into the pulmonary capillaries, while _______ diffuses out of the pulmonary capillaries and into the alveolar sacs.
Answer: Oxygen; Carbon Dioxide
Explanation:
Oxygen diffuses out of the alveoli and into the pulmonary capillaries, while carbon-dioxide diffuses out of the pulmonary capillaries and into the alveolar sacs.
What are pulmonary capillaries?PULMONARY CAPILLARIES: Deoxygenated blood enters into the pulmonary arteries from the right side of the heart and is delivered to the pulmonary capillaries, the smallest blood vessels inside of the lungs, attached to the walls of the alveoli.
Moreover, oxygenated blood then passes from the capillary beds through venules into the pulmonary veins. The pulmonary veins transport it to the left atrium of the heart.
Therefore, the pulmonary arteries are the only arteries that carry deoxygenated blood, and the pulmonary veins are the only veins that carry oxygenated blood.

The T-Rex diagram relates to the evolution of species on planet Earth.
The following images are shown in this diagram:
A T-Rex dinosaurA drawing of the planet EarthA drawing of grassA drawing of a cowA drawing of a humanThese 5 pictures can be related to finding the main message of the diagram. This diagram can be interpreted as the evolution of species on planet Earth because a dinosaur is shown first, a species that lived millions of years ago.
An image of the Earth is then displayed showing the familiar shape of the continents to demonstrate evolution on the Earth's surface.
Then show the grass because this represents the evolution of plant species that were expanding throughout most of the Earth.
Subsequently, a cow is shown as an example of the mammalian animals that exist today and finally the human who is the product of various evolutionary processes that resulted in the society and the world that we know today.
