Some years ago, before crude oil prices became an economic concern and an international political issue, a biologist proposed a curious-sounding plan. He suggested that a portion of our crude oil supplies be converted directly into edible food, instead of distilling it to gasoline for the typical farming methods for raising food.
Before you become nauseated at the idea, you should know that this conversion has been done on a trial basis. Making edible, non-toxic food from petroleum is feasible. Also, considering that the components of fossil fuels were once ordinary plants and animals in an ordinary food chain, maybe there is some logic in his plan. What does crude oil amount to, anyway, but dinosaur fat? (No, really it is primarily formed from microscopic organisms.)
It might be the right time to form a new corporation and market a new product. What shall we call it…”DinoSnack,” maybe? With interest in dinosaurs as high as it is, how can we go wrong?
Your task is to evaluate this suggestion, allowing for both pro and con, the positive and the negative aspects of it. Surely there will be economic and political considerations, but concentrate especially on the biological, ecological factors.
OK, this sounds like a winner, because…

Explain how climate change connects to a common resource?
Explanation:
The evidences of climate change abound. However, its explanation to ordinary farmers for better understanding should involve a historical comparison of the past and present climates in their respective localities especially as it relates to their farming activities. For instance, inception and duration of rainfall in the past and present, the past and present trend in temperatures, in their localities can be used to illustrate evidences.
Climate change has both direct and indirect effects on productivity of agricultural productions which include changing drought, and the geographical redistribution of pests, flooding, rainfall pattern and diseases.
What are the factors affecting the climate?There are several natural or man-made factors that can lead to changes in climatic conditions and hence change the common resources.
The factors that affect climatic conditions are:
Elevation or altitude.Topography.Geography.Global warming, etc.As the climate changes it starts affecting the common resources. It affects agricultural productivity. It can also alter the energy needs and energy generation potential.
Thus, this is the connection between climate change and common resources.

3.The 3-dimensional double helix structure of DNA, correctly elucidated by James Watson and Francis Crick. Complementary bases are held together as a pair by hydrogen bonds.
4.Chargaff's realization that A = T and C = G, combined with some crucially important X-ray crystallography work by English researchers Rosalind Franklin and Maurice Wilkins, contributed to Watson and Crick's derivation of the three-dimensional, double-helical model for the structure of DNA.
5.Created by Rosalind Franklin using a technique called X-ray crystallography, it revealed the helical shape of the DNA molecule. Watson and Crick realized that DNA was made up of two chains of nucleotide pairs that encode the genetic information for all living things.
6. 1869
7.The double helix of DNA is, like its name implies, in the shape of a helix which is essentially a three dimensional spiral. The double comes from the fact that the helix is made of two long strands of DNA that are intertwined—sort of like a twisted ladder.
8. In DNA, the code letters are A, T, G, and C, which stand for the chemicals adenine, thymine, guanine, and cytosine, respectively. In base pairing, adenine always pairs with thymine, and guanine always pairs with cytosine.
9. A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. ... Every person has two copies of each gene, one inherited from each parent.

11. A group of disorders that cause red blood cells to become misshapen and break down.
With sickle cell disease, an inherited group of disorders, red blood cells contort into a sickle shape. The cells die early, leaving a shortage of healthy red blood cells (sickle cell anaemia) and can block blood flow causing pain (sickle cell crisis).
12. Sickle cell anemia is caused by a mutation in the gene that tells your body to make the iron-rich compound that makes blood red and enables red blood cells to carry oxygen from your lungs throughout your body (hemoglobin).
13. The Human Genome Project was an international scientific research project with the goal of determining the base pairs that make up human DNA, and of identifying and mapping all of the genes of the human genome from both a physical and a functional standpoint.

What are two ways in which ultrasound technology produces images?
A. By the absorption of sound waves in the body
B. By detecting the frequencies of emitted sound waves
C. By using sound in frequencies that reflect off body tissues
D. By measuring the time it takes for reflected sound waves to be
detected
C and D
Hope this helps have a great day!!
The ultrasound images are produced by using the sound frequencies that reflect off body tissues and by measuring the time it takes for reflected sound waves to be detected. So the correct options are C and D.
What is ultrasound imaging?High-frequency sound waves are used in ultrasound imaging, also known as sonography, to look within the body.
Real-time ultrasound imaging allows for the display of blood flowing via blood vessels as well as the activity of the body's interior organs.
Contrary to X-ray imaging, ultrasonic imaging does not expose patients to ionizing radiation. A transducer (probe) is positioned either on the skin or within a bodily orifice during an ultrasonic examination.
To allow the ultrasonic waves from the transducer to pass through the gel and into the body, a small coating of gel is placed on the skin.
The ultrasound picture is created as a result of the waves' reflection off the body's structures. The information required to create a picture is provided by the intensity (amplitude) of the acoustic signals and the duration of the wave's passage through the body. Therefore the correct options are C and D.
