Carbon found in the air is converted into Oxygen through photosynthesis. Us humans and other beings breathe in the air and turns it into Carbon Dioxide. Carbon is also found in living beings. When living beings die or sink such as phytoplankton, they become rocks who eventually become fossil fuels, gas, or coal. These elements when burned in factories by us humans, they release carbon into the atmosphere creating a cycle of carbon being created and formed into other things.

Which of the following is true about adaptation?

I. It is random.
II. It results from genetic mutations.
III. It only affects an individual in a population.

I, II, and III
I and II
II and III
I only

Answers

Answer: I and II

Explanation: so basically,  when adaptation occurs, it usually happens over a long period of time due to climate, predators, etc. because of these adversities,  Genetic mutations occur, helping that animal and its species as a whole survive, which checks number 2. number one is also correct because adaptation can not be predicted. it happens randomly at some point in time. 3 is incorrect because multiple offspring in a species could have adaptations that provide more of an advantage.

Answer:

No they cannot fly

Explanation:

Penguins dont have any feather to fly with

Answer:

Well, in a sense they really do fly, only through the water, not through the air. Their wing bones are fused straight, making the wing rigid and powerful like a flipper. Penguins don't really need to fly because they dive deep, and swim so that they can catch their prey. Their bodies have huge fat supplies, heavy muscles, and densely packed feathers. There’s no way they could fly with such short wings and heavy bodies.

1. What is the significance of the specific gravity of the abnormal urine?

Answers

Answer:

A very high specific gravity means very concentrated urine, which may be caused by not drinking enough fluid, loss of too much fluid (excessive vomiting, sweating, or diarrhea), or substances (such as sugar or protein) in the urine.

Explanation:

Urine specific gravity is a significant and convenient way to measure the abnormal urine. It indicates dehydration or presence of substances in the urine as in case of diabetes.

What is Specific gravity?

Urine specific gravity (USG) measures the concentration of particles which are present in the urine and the density of urine compared with the density of water. Measurement of USG is an easy way and very convenient way to know a patient's hydration status as well as the functional ability of kidneys.

Urine specific gravity falls between the range of 1.002 and 1.030 if the kidneys are functioning normally. However, if specific gravity results above 1.010 this can indicate mild dehydration in that person. The higher the number of specific gravity, the more dehydrated a person may be.

A very high specific gravity means very concentrated urine, which may be due to not drinking enough fluid, loss of too much fluid, or substances such as sugar or protein in the urine.

A. Prokaryotes do not use acetyl CoA.
B. The process occurs in the cytoplasm of Eukaryotes.
C. The process occurs in the mitochondria of Eukaryotes.
D. Eukaryotes do not produce carbon dioxide.
E. Prokaryotes do not produce FADH2.

Answers

Answer:

C. The process occurs in the mitochondria of Eukaryotes.

Explanation:

In eukaryotes: glycolysis takes place within cytosol, Krebs cycle within mitochondrial matrix & ETC within inner mitochondrial membrane. Prokaryotes undergo binary fission(only cytokinesis) & conjugation.Prokaryotes undergo binary fission(only cytokinesis) & conjugation. Eukaryotes perform mitosis, meiosis(both karyokinesis and cytokinesis).

Therefore in prokaryotic cells, the citric acid cycle occurs in the cytoplasm; in eukaryotic cells, the citric acid cycle takes place in the matrix of the mitochondria.

Acetyl-CoA reacts in the first step of the eight step sequence of reactions that comprise the Krebs cycle, all of which occur inside mitochondria of eukaryotic cells. While the Krebs cycle does produce carbon dioxide, this cycle does not produce significant chemical energy in the form of adenosine triphosphate (ATP) directly, and this reaction sequence does not require any oxygen. Instead, this cycle produces NADH and FADH2, which feed into the respiratory cycle, also located inside of the mitochondria. It is the respiratory cycle that is responsible for production of large quantities of ATP and consumption of oxygen. In addition, the respiratory cycle converts NADH and FADH2 into reactants that the Krebs cycle requires to function. Thus, if oxygen is not present, the respiratory cycle cannot function, which shuts down the Krebs cycle. For this reason, the Krebs cycle is considered an aerobic pathway for energy production.

explaining how carbon is
transferred within and
between organisms and the
environment.

Answers

Answer:

For example, in the food chain, plants move carbon from the atmosphere into the biosphere through photosynthesis. They use energy from the sun to chemically combine carbon dioxide with hydrogen and oxygen from water to create sugar molecules.

Describe: Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants get rid of carbon dioxide gas through a process called respiration. Carbon dioxide is added to the atmosphere naturally when organisms respire or decompose (decay), carbonate rocks are weathered, forest fires occur, and volcanoes erupt. Carbon dioxide is also added to the atmosphere through human activities, such as the burning of fossil fuels and forests and the production of cement. Organisms play an important role in the carbon cycle in the following ways: Plants absorb carbon from the environment in photosynthesis and return it in respiration. Animals obtain their carbon by eating plants; they release carbon in respiration.

In the early days of arctic exploration, dogsled was often the only way to travel. The ice, snow, and extremely cold weather made using other animals, such as horses, impossible. Snowmobiles were not invented yet. Most explorers journeyed by ship until the ice made it impossible to continue. Then, they would switch to dogsled. The dogs, working together, were a well-oiled machine that could cover long distances in the cold. Sled dogs needed to have long, warm coats to survive the arctic temperatures. They had to be fast and able to run for long distances while pulling a heavy load. Most importantly, they had to work together as a team. This made northern dogs, such as Siberian huskies and Alaskan malamutes, the best choices for the sled teams. These dogs have long coats, with a double layer of fur to keep out the cold, and they have wide paws with webbed toes that act like snowshoes. They have been bred for more than 9,000 years to be working dogs in extreme winter weather. They are friendly, team-oriented, and purposeful dogs. In the days of the arctic explorers, the physical features and determined personalities of the sled dogs made long journeys in harsh conditions possible. To be in the best condition for pulling heavy loads, the dogs needed a diet that was high in fat. They ate whale and seal blubber and fatty meats during their long journeys, which kept them strong and gave them energy to keep going. The dogs' paws also needed special care to make sure that they did not become injured by sharp ice or extreme cold. Treating the paws with fat or wax helped the dogs to run safely and comfortably. Although the days of arctic explorers are long past, sled dogs continue to run through the snow and ice of the North. Dogsledding is now recognized as a sport, with many competitions taking place all over the world. One of the most well-known of these is the Iditarod, a race of almost 1,000 miles. It commemorates the Great Race of Mercy that took place in 1925 when dog sled teams were the only hope of a town that needed life-saving medicine. The race takes 811 days to complete and is run regardless of weather conditions. Teams of twelve or more dogs train with their handlers for years before competing. The race is long and one of the most challenging in the world. Dogs and their handlers must be in top physical condition to have any chance of winning.During the race, the dogs get multiple rest stops and are checked by veterinarians to make sure they avoid injuries. They eat high-fat, high-protein foods to give them the energy to continue, just like the dogs of the arctic explorers did. With the same determination that drove the dogs of the 1925 Great Race of Mercy, the dogs competing in the Iditarod run through even the worst blizzards and race to win.Which reason supports the author's point that dogs and their handlers must be in top physical condition to compete in the Iditarod? Dogsledding is now recognized as a sport, with many competitions throughout the world. Sled dogs need special diets and care to prevent injury or sickness. The race commemorates the extraordinary Great Race of Mercy that took place in 1925. The race is 1,000 miles long and challenging, taking place no matter the weather conditions.
