Answer:

; (1.8 meters per minute)

Step-by-step explanation:

Use dimensional analysis to solve this problem.

The proper units of conversion are given in parentheses on this question: 100 cm = 1 m.

Start with the given value, 3 centimeters/1 second.

Convert this rate to meters/minute by multiplying 3 cm/1 sec by 1 m/100 cm.

The top and bottom units should cancel out, so that's how you know to put the cm units on the bottom to cancel out with the 3 cm on the top.

Multiply the fractions together. The "cm" units cancel out.

Now you want to make the bottom units = minutes. There are 60 seconds in 1 minute, so you can use  to multiply with .

The "seconds" unit cancels out, so you are left with meters on the top and minutes on the bottom. Multiply the fractions together.

We want the rate to be meters per minute (1), so completely simplify this fraction and divide the fraction by (100/100), so the denominator is 1 min.

IM SORRY THIS IS SO LATE!!!

Explanation:

The first step of digestion begins the moment the food on your plate touches your lips and goes into your mouth, believe it or not, teeth are part of the digestive system! Your teeth help chew and grind the food into smaller pieces, which makes it easier to swallow. Saliva then continues to break down the food further by converting starches to sugars, with the help of the enzyme that is in saliva called amylase. Once this occurs the food particles that are left will be passed down to the esophagus. The esophagus is a muscular tube that is on average ten inches long and about one inch wide. It passes food down by using many different contractions to force food and liquids into the stomach. When the food reaches your stomach, it begins to churn and move which ends up grinding the food. To do this the stomach produces juices that break down the tissues of meat. This stomach juice is known as gastric juice, it is a mixture of acid, enzymes, and water. The stomach empties out a small amount of food every thirty minutes to the small intestine. The food stays in the small intestine for approximately ten hours. During this time, the food slowly dissolves into the blood. The blood then carries the digested food to all parts of the body. The inside of the small intestine is a wall made of hundreds of small fingers called villi. Each villus has its own tube to take in the dissolved digested food. Since some food remains after the food has been digested this food is passed on to the large intestine. These waste remains are passed out of the body through the lower part of the colon known as the rectum. Studies have shown that having a good diet is especially important to have a healthy colon, some foods to eat that are good for you are celery, lettuce, and cabbage.  

  I would personally eat the apple since a nice, juicy, and crispy apple sounds much more appetizing than a chocolate candy bar. The reason I would eat an apple is because if you are looking for a healthy snack and compare the nutrition facts it is surprisingly a closer call than I anticipated. The apple has 19 grams of sugar and the candy bar has 21 grams of sugar. Going off that the apple is a better choice. If we go off carbohydrates there are both 25 grams, so that would be by just choice if we go off that. If we look at all the nutrition facts and long-lasting effects in 2018 Journal of Food Composition and Analysis showed that processed chocolate had unsafe levels of cadmium and nickel. This is a huge long-term affect that can cause permanent damage in your body that you will not realize right away. When you eat an apple a day though there are many more positive health benefits for example, apples help with keeping a healthy good balanced gut health. They also provide 14% of the recommended daily use of vitamin C. Now a chocolate candy might solve your cravings for sugar but in the future, there are way more positive effects if you eat an apple instead of a chocolate. Considering all these factors I would rather eat an apple.

Answer:In particular the epithelial cells lining the small intestine. ... They will therefore have a large surface area provided by the microvilli and due to the need for active transport across their cell membranes they will contain a large number of mitochondria providing them with ATP.

Explanation:

I’m Diffrent

Epithelial cells have many mitochondria because such cells desperately have high levels of energy output and significantly require the ATP that is considerably synthesized by mitochondria.

Mitochondria may be defined as a double membrane-bound cell organelle present in the cytoplasm of the cell. Mitochondria are known as the "Powerhouse of the cell" because the energy required for various activities is produced by this specific cell organelle in the form of ATP.

The epithelial cells of organs like lungs, alveoli, intestines, kidneys, etc. facilitate the absorption of nutrients along with gases that remarkably provide a filtration barrier. These processes necessarily require high levels of energy output.

Therefore, epithelial cells have high levels of energy output and significantly require the ATP that is considerably synthesized by mitochondria.

Answer:

The answer is decrease friction

Answer:

to decrease friction

Answer: Way colder

Explanation:

The greenhouse gases in the atmosphere are found to be responsible for the increase in temperature. If the atmosphere does not contain greenhouse gases then the earth's temperature will be colder than that with greenhouse gases.

A greenhouse gas absorbs and emits radiant energy within the thermal infrared range which causes the greenhouse effect. Greenhouse effect leads to increase in the atmospheric temperature of the earth.

The main gases responsible for the greenhouse effect are carbon dioxide, methane, nitrous oxide, and water vapor, and fluorinated gases.

The natural greenhouse effect is caused by the greenhouse gases which are present naturally, and is vital to life. In the absence of the natural greenhouse effect, the Earth would be approximately 33°C cooler.

Answer:

The phase of the cell cycle description corresponds to the interphase, specifically, the G1 stage.

Explanation:

The interphase is the previous step before mitosis occurs. The interphase is formed of the G1, S, and G2 stages.

During the G1 stage, it occurs a high and intense biochemical activity. The cell duplicates its size, and the organelles and other molecules and cytoplasmatic structures duplicate too. Some structures, such as microtubules and actin filaments, are synthesized from zero. The endoplasmic reticulum increases and produces a membrane for the Golgi apparatus and vacuoles, lysosomes, and vesicles. During this stage, the pair of centrioles separate, and each centriole duplicates.  

The stages S and G2 follow the G1. Once the whole interphase is completed, mitosis occurs.  

The correct phase of the cell cycle description given is - G1 phase of interphase.

It is the phase in the cell cycle that has three stages G1, S, and G2. The most of the cell lifetime the cells are in interphase and in interphase the G1 phase.

G1 Phase

In this subphase, the rate of cell growth varies that depends on the type of the cell. The cell grows and cellular structures are doubled by protein and mRNA synthesis.

Answer:

D)4

Explanation:

The graph has to have exponential growth in the beginning, ruling out 3. Then, the paragraph states the moth was introduced to slow the spread. 1 is all over the place and inconsistent, and 2 is basically taking the cactus away. 4 is leveling out the exponential growth, so it's 4

The graph that best describes the changes in population growth of the cactus before and after the introduction of the moth is four.

Population growth may be defined as the increase in the number of individuals in a population over a certain period of time in a given area.

Graph four describes the phenomena of exponential growth, which means that before the introduction of the moth the population of cactus rose rapidly. But as the moth was introduced, the population of cactus slows down not completely decreases.

Therefore, the graph that best describes the changes in population growth of the cactus before and after the introduction of the moth is four.
