Answers

Answer:

B is the answer. Glucose and oxygen are given off during Photosynthesis

The cells in this leaf are making their own energy by the process of photosynthesis, where carbon dioxide and sunlight at Q and R are taken in and then converted into glucose and oxygen at S and T.

What do you mean by photosynthesis?

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.

In plants and algae, which developed much later, photosynthesis occurs in a specialized intracellular organelle—the chloroplast. Chloroplasts perform photosynthesis during the daylight hours. The immediate products of photosynthesis, NADPH and ATP.

Photosynthesis is critical for the existence of the vast majority of life on Earth. It is the way in which virtually all energy in the biosphere becomes available to living things.

The formula for the volume V of a cylinder is V = πr2h where r is the radius of the base and h is the height of the cylinder. Solve the formula for h. Then find the height of a cylinder with a volume of 36πcm3 and a base with a radius of 3 cm. Please help me its due today

Answers

Answer:

h = 4 cm

Explanation:

First, we solve for h.

h=[tex]\frac{V}{pi*r^2}[/tex]

h = unknown

v = 36*pi

WHICH RESERVOIR OF THE CARBON CYCLE CHANGES THE MOST AND THE QUICKEST?
(please helpp)

Answers

the ocean is the reservoir that changes the most and the quickest

The reservoir of the carbon cycle that changes the most and the fastest is the atmosphere, as the atmospheric carbon pool changes due to the constant release of carbon dioxide through household sources and cellular respiration.

What is the significance of the carbon pool?

The carbon pool maintains the carbon ratios in the earth, as the atmosphere is the reservoir of the carbon cycle that changes the most and quickest due to burning fossil fuels, usage of household electric appliances, usage of more vehicles that release carbon dioxide, deforestation, etc. If the carbon pool is not maintained and becomes uncontrolled, the environment will be harmed due to global warming, etc.

Hence, the reservoir of the carbon cycle that changes the most and the fastest is the atmosphere, as the atmospheric carbon pool changes due to the constant release of carbon dioxide through household sources and cellular respiration.

Somoene please help and explain how to read the graph!!

Answers

Answer:

Whats going on is that you have a specific amount of enzyme that can do a specific amount of work. Think of it like a hotdog stand. the enzyme would be you and your substrats are your hot dogs and buns. You can only go as fast as the materials you have. If you have more materials than hands you can only go as fast as you can make them. To many substrates and you enzyme rate will cap out at maximum speed.

Explanation:

The plot shows rate of reaction of an enzyme as a function of the concentration of substrate. At stage B, the rate flattens and becomes constant, which means there's too much substrate for the enzyme to handle. So the fourth statement is false - the rate of reaction cannot be increasing.

C: Corresponding temperature and wind patterns
D: Similar ocean currents and vegetation

Answers

C: Corresponding temperature and wind patterns are in common.

What are the 3 characteristics of climate?

The simplest way to describe climate is to look at average temperature and precipitation over time. Other useful elements for describing climate include the type and the timing of precipitation, amount of sunshine, average wind speeds and directions, number of days above freezing, weather extremes, and local geography.

Climate features also include windiness, humidity, cloud cover, atmospheric pressure, and fogginess. Latitude plays a huge factor in determining climate. Landscape can also help define regional climate. A region's elevation, proximity to the ocean or fresh water, and land-use patterns can all impact climate.

Answers

Collagen has: A. pyrrolidine rings, which stabilize helices and glycine residues at every third position (because only glycine residues can fit inside of the super-helical cable).

Collagen can be defined as the main or most abundant structural protein found in the bones, tendons, connective tissues, skin and muscles of a living organism such as a human being.

Basically, collagen is a chemical substance (protein) made up of amino-acids and it holds the human body together.

Hence, collagen typically makes up about 30% of the proteins contained within the human body.

Additionally, collagen comprises the following specific amino-acids:

Hydroxyproline.Glycine.Arginine.Proline.

Each of the three chains of a collagen triple helix with 3.3 residues per turn, is normally stabilized by the steric repulsion between the pyrrolidine rings of hydroxyproline, glycine and proline residues.

Therefore, the pyrrolidine rings of collagen helps in the stabilization of helices and glycine residues, at every third position because the only residue that fits inside of the super-helical cable is the glycine residues.

9. Ginny the Dog: A Hero Among HeroesHeroes come in many shapes and forms, but they all do uncommon things in unusual situations. They stand out. We've all heard stories of hero dogs that save their owners. One dog saved his owner by fighting off an alligator. Another woke his sleeping family when a fire broke out in its home. Still others rescue injured or needy people in dangerous situations. One dog even managed to call 911 when his owner suffered a seizure. But one dog, named Ginny, performed heroic acts on a regular basis, not just once or twice in unusual situations. Because of her kindness, many lives were saved.Ginny the dog was adopted by her owner from an animal shelter in 1990. Within days of bringing her home, her owner discovered that Ginny seemed to be able to find cats in distress. On her daily walks, Ginny would often find abandoned, trapped, or endangered kittens or cats that needed rescuing. In one such episode, Ginny found a group of kittens trapped in a pipe. She managed to let her owner know, by scratching and barking at the pipe, that something needed her help. Because of Ginny, all the kittens were saved.Almost daily, Ginny would find cats that needed rescuing or, in some cases, a little love. Ginny's owner reported that when Ginny saw a cat on their walks, she would pull away from her leash and run after the cat. Instead of chasing cats like most dogs, Ginny would nuzzle and lick them, giving them comfort. Because of Ginny, her owner soon found he was caring for hundreds of wild neighborhood cats. In addition, Ginny pushed her owner to adopt more than 20 cats, most of whom had permanent injuries or special needs."When we would go to the pound to drop off donations," her owner said, "Ginny always found the cat that was blind or deaf or hurt in some way. She would sit down in front of the cat's crate and not move until we brought it home."What makes a dog behave in such a kind way? Some believe Ginny had a very strong mothering instinct. But how could she tell when a cat was deaf? How did she know which cats needed love and attention? Regardless of how she did it, Ginny rescued hundreds of cats in her life and set an example we all can follow.Read these lines from the text:When we would go to the pound to drop off donations," her owner said, "Ginny always found the cat that was blind or deaf or hurt in some way. She would sit down in front of the cat's crate and not move until we brought it home.What is the main purpose of this quotation?A To create awareness of animal sheltersB To encourage readers to do further research on animal behaviorC To suggest Ginny had something that humans lackD To explain how Ginny got him to adopt cats Which scenario describes an interaction between two of Earths spheres?ASAP HELP PLSSA.Water flows from a stream to a lake.B.Gravity moves rocks to another location.C.Lions use energy to catch other animals for food.D.Bears dig big holes in the ground to protect their young. a square has a perimeter of 6x - 20 units.
