In the earliest stages of development the embryos of a fish, calf, human, and tortoise all look similar. In the next stage the fish looks the most different. What assumption can be made based on this different?

The correct assumption may be that the calf, human and the tortoise are more related to one another as compared to the fishes.

The embryology plays a very important role in determining the common ancestors in the organism. The organisms sharing similar embryological development are more closely related as compared to the others, which do not have the similarity in the embryogenesis. More closely related the organism, the more similar embryonic development would be. Hence, it can be said that the calf, human and the tortoise are closely related to one another as compared to the fishes.

A scientist wrote an article about a drug that he believes reduces the effects of viral infections. Which of these MOST LIKELY needs to be done by a scientific committee before the drug is made available to the general public? A) An experiment related to the drug but not about viral infections B) A review of the scientist’s credentials and a review of the article C) An experiment not related to the drug but about viral infections in general D) An experiment related to the drug and a review of the article written by the scientist

Answer:

The answer is d)An experiment related to the drug and a review of the article written by the scientist

Explanation:

A scientific committee will verify that the medication has been evaluated in its entirety before placing it at the disposal of the general public, and for this it should be verified that said medication is supported through scientific experimentation, which will help establish the nature between independent variables and dependents. In a controlled study of a drug, scientists conduct two or more experiments simultaneously: a treatment group, where the effect of manipulation on a dependent variable is analyzed, and a control group, in which the same conditions are used, to treatment exception.

In a paragraph address these following questions: • How does an underwater earthquake cause a tsunami? • Why do some earthquakes cause more damage than others? the paragraph needs to also include the following things: • discuss how the different types of waves are formed and describe how the waves travel • explain how scientists use waves to track and analyze earthquakes • cover recent events involving earthquakes and/or tsunamis that illustrate the points made in your explanation

What is an Earthquake

Earthquakes are vibrations in the earth's crust They occur along all plate boundaries but are more destructive usually at destructive plate boundaries

How are they measured

The magnitude or size of an earthquake can be measured by an instrument called a seisometer and are shown on a seismograph. The earthquakes are measured on the Richter scale from a value of 1 to 10. Each level of magnitude is 10 times more powerful than the previous. Therefore a level 7 is 100 time more powerful than a level 5.

Why do some earthquakes cause more damage than others?

Some earthquakes take place in rural areas where few people live and little is damaged

If they occur near large urban areas with many people, transport services, large buildings and services such as gas and electricity - there can be a great amount of deaths and damage

In Poor countries - LEDC's they have poorly built buildings, few emergency facilities, and the equipment to help rescue people - a good term to use is that they have a poor infrastructure.

In rich countries - MEDC's such as the USA they prepare for an earthquake with drills and have a great deal of trained emergency personnel and equipment to go to help the injured. They also try to build to withstand earthquake damage - ie The Transamerica building

The time of day can be important - If the earthquake hits when it is the rush hour or when there is a large number of people located in a certain area - this can cause a great loss of life

Obviously if they occur near to coasts then Tsunamis can cause a great deal of damage and deaths such as the 2004 Boxing Day Tsunami

Landfills are waste disposal sites. They are often man-made depressions in the ground covered with a lining designed to prevent any leakage of waste materials. However, landfills can leak through the base resulting in negative impacts on the surrounding environments. What negative impact to the environment is caused by the production of methane gas in landfills?

The landfill gases have a negative effect on climate change. The prime constituents are methane and carbon dioxide, both of these are greenhouse gases. In terms of global warming, methane is over twenty-five times more harmful to the atmosphere in comparison to carbon dioxide.  

The emission of methane gas from the landfills can result in hygiene, environmental, and security issues in the area surrounding the landfills. In supplementation to the threat of explosion and fire, the migration of gas in the subsurface can lead to exposure of methane gas with the groundwater, thus, contaminating the source of water.

Soo A nucleic acid sequence is a succession of letters that indicate the order of nucleotides within a DNA (using GACT) or RNA (GACU) molecule. By convention, sequences are usually presented from the 5' end to the 3' end. For DNA, the sense strand is used. Because nucleic acids are normally linear (unbranched) polymers, specifying the sequence is equivalent to defining the covalent structure of the entire molecule. For this reason, the nucleic acid sequence is also termed the primary structure.

The sequence has capacity to represent information. Biological deoxyribonucleic acid represents the information which directs the functions of a living thing.

Nucleic acids also have a secondary structure and tertiary structure. Primary structure is sometimes mistakenly referred to as primary sequence. Conversely, there is no parallel concept of secondary or tertiary sequence

If 20% of a DNA sample is made up of thymine, T, what percentage of the sample is made voof cytosine, C?A. 15%B. 30%C. 35%D. 50%

Answer:

B. 30%

Explanation:

DNA has four type of nitrogenous bases in its nucleotides named as adenine, thiamine, cytosine and guanine and the abbreviations for these bases are A, T, C and G respectively. DNA is a double stranded bio molecule and the nucleotides of both the strands of DNA are joined with each other with the help of either double bonds or triple bonds which exist between the nitrogenous bases of its nucleotides. There are two type of bases, purines and pyrimidines. Adenine and guanine are purine bases while cytosine and thiamine are pyrimidine bases.

Chargaff's base pair rule says that the ratio of purine bases with respect to pyrimidine bases must be 1:1 ratio. It can be possible only if a purine base pairs with pyrimidine base of the adjacent DNA helix. So, adenine which is a purine always pairs up with thiamine which is a pyrimidine with the help of two hydrogen bonds while guanine being a purine always pairs up with cytosine which is a pyrimidine with the help of three hydrogen bonds. It simply means that a DNA molecule will have as many adenine as many there are thiamine. Also, for the same reason there will be as many cytosine as many there are guanine.

So, 20% of T means same amount of A which is 20%. Hence, A and T will together form 20% + 20% = 40% of the sample.

In the remaining 60% sample the amount of C and G is equal that means it will have 30% C and 30% G.

So, the answer is 30% C or cytosine.

Answer: If a decision was made to convert forest to agriculture then the example of negative trade off based on this decision will be plants and animals. Forest serves the animals with food and shelter and with the decision of shifting all the forests into agricultural land, the animals will have to migrate to another place. They will be diminished as a effect of this.
