Your science teacher brings in a speaker to talk to your class about climate change. During the session, students ask a few questions. Which questions are related to the current evidence on climate change? 1. Where on Earth has the population decreased in the last decade?
2. What is the average cost of a college education per person?
3. By what rate has the melting of glaciers increased?
4. Where are the average temperatures changing on Earth?
5 If the global climate is warming, why were there record-breaking cold spells last winter?

Answers

Answer 1
Answer:

Answer:

Climate change is any remarkable long-term change in the weather of a region (or the whole Earth) over a considerable period of time. Climate change is about abnormal variations to the climate, and the effects of these variations on other parts of the Earth.                                                                                    

From the definition above, questions 3, and 5 are clearly related to current evidence on climate change.

  • The rate at which the the glaciers are melting is an after effect of global warming viz a viz climate change.
  • record-breaking cold spells can also be an after effect of climatic change.

Question 4 seems related too however, it speaks to average temperature change. Temperature change may be an evidence of climatic change if it occurs to a great degree over a long period of time. So the phrase "average change" is neither here nor there.

Cheers!

A population of white rabbits and brown rabbits both live in a temperate deciduous forest where the summers are mild and average about 50°f. The winters are often below freezing. If warmer temperatures last longer into the fall and the average temperature in the winter is getting warmer?

Answers

Answer:

Q: ...what do you expect to happen to the population of each color of rabbit?

A: The white rabbit population may slowly die off while the brown rabbit population thrives and reproduces.

Explanation:

The white rabbits are well adapted to survival in cold winter months and snowfall, where they may camouflage effectively to avoid predation. However, the brown rabbits, more adapted to warmer periods in the fall, spring and summer in the temperate deciduous forest; the trees lose their leaves before cold seasons.

Leaf litter and foliage in warmer months likely provides better camouflage for brown rabbits. Camouflage is an adaptation to predation; the rabbits blend into surrounding colors, textures and patterns to avoid detection.  In the onset of shorter winters, the white rabbits will be unable to avoid predators without snow to blend into; they would contrast with their surroundings making them easy targets to be hunted. Thus, with extended periods of warm temperatures, brown rabbits are more likely to survive and reproduce leading to a thriving population.

Biological molecules you are what you eat worksheet answers

Answers

Biological molecules are also known as biomolecules are what we eat. They are what all living things needed to survive. They come in form of carbohydrates,  proteins, lipids, and nucleic acids.  

Food gives the body the nourishment it requires to survive. Many of these essential nutrients are biological macromolecules or big molecules that are required for life. These macromolecules called polymers are composed of various arrangements of smaller organic molecules called monomers.

Carbohydrates, lipids, proteins, and nucleic acids are the four primary groups of biological macromolecules; each one is a significant cell constituent and serves a variety of activities. 

Carbohydrates are a necessary component in our diet;

  • cereals,
  • fruits, and;
  • vegetables

are all organic sources of carbohydrates.

Carbohydrates supply energy to the body, notably glucose. It is a simple sugar found in starch and found in many basic meals.

Proteins are the most common organic molecules in biological systems and it is the most universal range of activities of any macromolecule. A biological system's cells may contain protein complexes, each with a distinct purpose.

Lipids are a broad category of molecules that are predominantly nonpolar in nature. In a cell, lipids play a variety of functions. Cells reserve energy in the form of lipids for long usage. 

Nucleic acids are the most crucial macromolecules for the continuation of life. They include the genetic information of a cell as well as information for the cell's functionality.

Therefore, we can conclude that the importance of biological molecules is important in human life.

In dna, a purine must always pair with a pyrimidine and vice versa in order to ensure that

Answers

In DNA, a purine must always pair with a pyrimidine and vice versa to ensure distance between the two phosphodiester backbones remains constant.

What is DNA?

Deoxyribonucleic acid is a polymer composed of two polynucleotide chains that coil around each other to form a double helix. The polymer carries genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses. DNA and ribonucleic acid are nucleic acids.

Moreover, DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases.

Therefore, DNA is made of nucleotides. A nucleotide has two components: a backbone, made from the sugar deoxyribose and phosphate groups, and nitrogenous bases, known as cytosine, thymine, adenine, and guanine.

When you wash an oily pan, dish soap aids in washing away the oil by surrounding the fat droplets and rinsing them away with the excess water. what similarities does this have to digestion in our bodies?

Answers

Our liver produces bile which is stored in the gall bladder and delivered to the stomach where the bile physically breaks down the fat droplets into smaller fat droplets to increase surface area to volume ratio so that enzymes can chemically break it down into simpler substances such as fatty acids and glycerol. The dish soap acts as the bile that physically breaks down the fat droplets into smaller fat droplets.

What is the name of the major volcano that erupted in 2010

Answers

Answer:

Iceland’s Eyjafjallajökull Volcano

Explanation:

Iceland’s Eyjafjallajökull Volcano eruption happened on March 20, 2010. It consisted of different stages:

  • The first eruption happened in an ice-free area (1660 m high), this eruption was little but it produced lava.
  • The next phase of the eruption, on 14 April, produced a 2.5 km wide caldera under the ice cap. This led to the melting of such ice, flooding the southern region, 800 people were evacuated. During this phase, the interaction between magma with water created a plume of volcanic ash and gas of over 10 km. This lasted from April 15th to April 21st.

Even though the eruption itself wasn't that big, the melting ice that flooded the surrounded area and the ashes column that blocked the air paths for almost a week, converted this event into one of the most disastrous eruptions.

I hope you find this information useful and interesting! Good luck!

How many high-phosphoryl-transfer-potential molecules are required to synthesize phosphatidylethanolamine from ethanolamine and diacylglycerol? Assume that the ethanolamine is the activated component.

Answers

Answer: 3(three)

Explanation:

In the biosynthesis of phosphatidylethanolamine from ethanolamine and triglyceride, 3 high energy molecules are used in the first and second step.

The first steps occur in the cytosol, where ethanolamine is phosphorlated with ATP to give phosphoethanolamine and ADP by the enzyme ethanolamine kinases, and in the next reaction which is the rate-limiting step, phosphoethanolamine react with cytidine triphosphate (CTP) to form cytidine diphosphoethanolamine. In this reaction two molecules of phosphate group is given off.

The third step occurs in the endoplasmic reticulum CDP-ethanolamine react with diacylglycerol to form phosphatidylethanolamine.

The answer is Three high energy molecules. One molecule of ATP to form phosphorylethanolamine and two molecules of ATP to regenerate CTP from CMP.
