Global warming is predicted to produce an increase in extreme temperatures and it is caused mainly by an increase in CO2 levels. The increasing temperatures are likely to cause a modification in air circulation patterns and increase evaporation, among others. These have consequences over climate and produce an increment over frequency and magnitude of extreme climatological events (like hurricanes). Also, global warming leaves no place for adaptation (as it is fast compared to biological adaptation), so many species are likely to go extinct, with important ecological effects. I consider these to be catastrophic effects.

A couple who are close family friends of yours are concerned that their children may have a high risk of inheriting cancer from one of them. write a paragraph that describes the steps you would take to 1) Identify if either or both of the parents may contribute to the risk of cancer. 2) explain to the parents how genes may lead to the development of cancers that are not inherited and 3) how they could identify if an embryo ham the genetic components that will lead to cancer?
1.If either or both the parents have cancer,then the risk for contributing in cancer is very high.This can be analyzed with the help of family tree or pedigree analysis.But,its not always that if either one or both parents have cancer than offspring will get cancer.
2.Most cancers are not inherited,most cancers are occur due to genetic changes which a person acquire during his lifetime.The mutations which occur in genes can lead to development of cancer even its not inherited.
3.Tumors may arise from embryonic cells and can be identified by biopsy.

The Gulf of Mexico dead zone that forms each summer at the mouth of the Mississippi River is caused largely by the input of agricultural fertilizers. Many scientists advocate restoring wetlands (as well as creating them) as a strategy to reduce the severity and extent of the dead zone. The idea is that plants in healthy intact wetlands will remove these nutrients from the water (during growth) and prevent their washing into the river and the Gulf of Mexico. List at least two potential benefits to this strategy, as opposed to a more traditional chemical intensive approach such as that used at most waste water treatment plants.
1. Restoring wetlands could be cheaper in the long run, once the ecosystem is restored it maintainace will not be as costly as that of water treatment plants.
2. This strategy also will be benefical for biodiversiy conservation and would bring ecosystems services to surrounding communities.
Define gluconeogenesis and lipogenesis. Under what conditions do they predominantly occur?
The process of producing glucose (sugar) from lipid (fat) or protein breakdown products, as well as from its breakdown products is called gluconeogenesis whereas the creation of fatty acids from nonlipid precursors is known as lipogenesis.
Gluconeogenesis predominantly occurs both in the kidneys and the liver, because phosphoenolpyruvate carboxykinase is inhibited by ADP. As a result, gluconeogenesis is encouraged in cells that are abundant in ATP and biosynthetic precursors.
The liver, adipose tissue, small intestine, kidneys, and mammary glands are the primary sites of lipogenesis. Additionally, it happens in blood lipoproteins and the digestive system. It is a metabolic pathway that is activated by the high availability of carbohydrates and is used to break down extra carbohydrates.

sediment, transforming these
materials into oil and gas?
cocos
Natural gas may also be produced from organic material at high enough pressure. The two basic factors that convert biological matter into fossil fuels are heat and pressure.
What transforms extinct animals into crude oil and natural gas?Algae and plants inhabited shallow oceans millions of years ago. The organic material was buried when it perished and sank to the bottom, where it mingled with other materials. The remnants of these animals were converted into fossil fuels over millions of years under extreme pressure and heat.
Layers of clay and sand have been covering dead creatures that were buried in the water millions of years ago. These decomposing organisms became petroleum and natural gas as a result of the lack of air, the high temperature, and the high pressure.
Only carbon and hydrogen are necessary for the conversion of organic matter (OM) into petroleum.

People pave over a large field to build a parking Which of the following describes how this action will likely affect the water cycle for this region ?
The rain will be able to run off more quickly on concrete and in a vast field, which will probably cause flooding in both areas.
What is meant by the water cycle?The continual movement of water on, above, and below the Earth's surface is referred to as the water cycle, also known as the hydrologic cycle or the hydrological cycle.
Concrete is less porous than soil, thus the water won't be able to seep back into the soil. The volume of water in subsurface aquifers would decrease as a result.
Additionally, the rain will be able to run off more quickly on concrete and in a vast field, which will probably cause flooding in both areas. Both of these would probably hasten the water cycle and have detrimental consequences for people.
Therefore, the correct answer is option c. Runoff into storm drains increases.

Which term describes an organism that remains in one place?
Sessile is the term used to describe an organism that remains in one place.
Why are some organism sessile?
Some animals such as corals and sponges are sessile. These animals don't expend their energy to catch their prey they live by attaching to a substrate. They choose a suitable spot to feed. They can be found on tree trunks, on rocks, and even in water.
Plants are typical example of sessile organism. They permanently grow in one spot taking nutrients from the soil and making use of the available sun for photosynthesis. Sessile organism doesn't have the ability to move from one place to another and it has a big advantage as they save energy and they also develop unique feeding mechanisms enabling them to survive in their habitat.
In summary, sessile organisms don't move yet they feed by attaching themselves to a substrate.

Which of the following has the highest average salinity?
w. Mediterranean Sea
x. Atlantic Ocean
y. Arctic Ocean
Z. Gulf of Mexico
Salinity is the measure of how much salt has been dissolved in a body of water. It significantly affects conductivity and has an impact on a variety of chemical properties of natural waters, as well as the biological processes that occur there.
Explain about the salinity?Lake describes the Dead Sea. The Salt Sea is another name for it. With a salinity of 33.7%, the Dead Sea is the saltiest body of water on earth.
Either grams of salt per kilogram of water or parts per thousand are used to express salinity. For instance, your salinity is 1g/kg, or 1 ppt (ppt, or ), if you have 1 gram of salt and 1,000 grams of water. Salt content in freshwater is typically less than 0.5 ppt.
The Atlantic Ocean is the saltiest of the five ocean basins. Near the equator and at both poles, salinity generally decreases noticeably, though for various reasons. The tropics, which are close to the equator, consistently get the most rain.

facilitated diffusion across a biological membrane requires ______ and moves a substance ______ its concentration gradient.
Facilitated diffusion is the process by which molecules diffuse across the plasma membrane with the assistance of membrane proteins like channels and carriers.
What main function of facilitated diffusion in membrane?Diffusion is the flow of chemicals across a biological membrane from an area of higher concentration to one of lower concentration, and it is facilitated by the usage of a transport molecule.
Because substances move in the direction of their concentration gradient, chemical energy is not directly needed.
Solutes diffuse through transport proteins in the plasma membrane when their diffusion is facilitated. A form of passive transport is facilitated diffusion.
Therefore, facilitated diffusion across a biological membrane requires transport proteins and moves a substance down its concentration gradient.

i have to make a model for class and i don’t understand anything i have to do, can anyone help me complete the model?Part 2 and 3.
Answer: I think maybe you could make an illustration about the process of photosynthesis and cellular respiration. Maybe you could print some images like the sun, leaves, and molecules. In the molecules like oxygen, carbon dioxide, water, you could just make small circles. You can put it all together by adding arrows to show the next step of the process.
2. Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body's cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP. Cellular respiration can occur both aerobically (using oxygen), or anaerobically (without oxygen). During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. The bonds are broken in glucose, and this releases the chemical energy that was stored in the glucose bonds. Carbon dioxide and water are created as byproducts. This process occurs in mitochondria.
3. In the two processes, we can see that the products of one process are reactants of another – and vice versa. Glucose and oxygen – which happen to be the products of photosynthesis, are required to facilitate cellular respiration, while carbon dioxide – which is a by-product of cellular respiration, is required to facilitate the process of photosynthesis.

Which of the following would result in an increase in plant growth?A. Decreased amount of other plant species, decreased amount of sunlight.B. Increase amount of other plant species, decreased amount of water.C. Decreased amount of herbivores, increased amount of sunlight.D. Increased amount of herbivores, increased amount of water.
All plants need the right temperature, light, water, air, and food to have a proper metabolism and to grow. The height of the plant is directly related to the number of nutrients in the soil and the light for its photosynthetic processes. On the other hand, the lower the number of herbivores, the less likely it is that the branches will be cut and the height of the plant will be reduced.
We can conclude that the correct answer is:
Answer:C. Decreased amount of herbivores, increased amount of sunlight.
