Vaccines are given to prevent spread of infectious disease, when researching and developing new flu vaccines, scientists are likely to focus on Europe because that is where flu originated from in the early 90's.
What is a vaccine?A vaccine is prepared to provide active acquired immunity against a particular infectious disease. It could be a virus or bacterial disease.
Influenza vaccines are prepared and given to protect against infection by influenza viruses.
This vaccine production will focus more on Europe because that is where it originated and there are possibilities of new strains developing and more prevalent as such, there is a need for more attention to be focused there.Therefore, when researching and developing new flu vaccines, scientists are likely to focus on Europe because that is where flu originated from.

There is much controversy surrounding stem cells and the use of them. Do you think the use of stem cells is ethical? Why or why not?
Answer:
Explanation:
Ethical issues Historically, the use of stem cells in medical research has been controversial. This is because when the therapeutic use of stem cells first came to the public’s attention in the late 1990s, scientists were deriving human stem cells from embryos.
Walruses live in the Arctic and have a thick fat layer. The ancestors of the modern-day walruses might not have had such a thick layer. Over time, the walruses have probably changed. According to the theory of evolution by natural selection, what is the most likely reason that this change has probably occurred?
Answer:
The walruses that had thicker fat layers were more apt to survive and live to reproduce
Answer:
Explanation:
The walruses gained a thicker layer overtime because they adapted to the cold environment allowing them to slowly grow a thicker layer of fat.

Describe how restriction enzymes and ligase enzymes are used to make the plasmids that are introduced to bacteria cells during transformation. Include the words sticky ends and complementary in your response.
Answer:
DNA restriction enzymes cut the DNA molecule, while DNA ligases join the resulting DNA fragments
Explanation:
Transformation is a naturally occurring process by which bacteria incorporate exogenous genetic material from their surrounding environment. This process (transformation) is used for DNA cloning via plasmid vectors. In DNA cloning, transformation occurs after restriction enzymes cut the DNA at specific sequences named palindromic sequences (i.e, sequences that can be read the same in opposite direction). Restriction enzymes can generate sticky-ends, where enzymes make staggered cuts in the two strands (e.g., BamH), or blunt ends, where the resulting strands are of the same length (e.g., HaeIII). In general, sticky-end enzymes are more useful because they generate a 3' overhang in one molecule and a complementary 5' overhang in the other, increasing the yield and specificity of ligation. During ligation, a DNA ligase is used to join both DNA strands by forming phosphodiester bonds in the plasmid. Following transformation, bacteria can be selected on antibiotic plates.

What have scientists realized over the years of how temperature affects humans? Does temperature affect climate change? If it does, how can it be reduced?
HELP!!!
Answer:
Temperature affects humans in many different ways.
Explanation:
Humans can be affected by temperatures because high temperature often can cause health problems, people may feel: Increased irritability. Loss of concentration and ability to do mental tasks. Also temperature doesn't really affect climate change, its more like the other way around. Thing you can do to reduce climate change are use renewable energy, and don't use cars if you don't have to. Because the gas that comes out of the cars turns into green house gas which is the cause of climate change.

Eastern Indigo snake. Which of the following describes the impact of Hurricane Charley on the Eastern Indigo snake?
1.Genetic diversity will decrease because of genetic drift caused by bottleneck effect
2.Mutations will decrease genetic diversity because the indigo snake became isolated
3. The snakes will learn to swim, become a new species, and emigrate to other parts of Florida.
4. The Easter Indigo will be forced to mate with other species of snakes and become a new species
Answer: the correct answer is actually
1.Genetic diversity will decrease because of genetic drift caused by bottleneck effect
Explanation: this is due to the bottleneck effect because the bottle neckeffect is when size or population decreases due to earthquakes human activity, etc;
1. Genetic diversity will decrease because of genetic drift caused by bottleneck effect

True or false wave energy can travel in all directions
Answer:
TRUE
The direction of energy transfer is perpendicular to the motion of the waveA: Waves do not always travel in the same directions as the currents. Waves are created by the wind and then radiate in all directions away from the disturbance. Currents represent the movement of water particles which is controlled by winds and density differences. Waves and currents can travel in opposite directions
