Group of similar cells that perform a particular function.

Answer:energy in the form of heat and matter (nutrients, solids, dissolved substances, and gases)

Explanation:

The correct answer is moss.

Mosses are seedless plants that have a dominant gametophyte generation. In the life cycle of mosses, the gametophyte generation is the dominant and most visible phase of the plant's life. The gametophyte produces reproductive structures called gametangia, which produce the male and female gametes (sperm and eggs). Fertilization occurs within the gametophyte, leading to the formation of a sporophyte generation. The sporophyte remains attached to the gametophyte and relies on it for nutrition. The sporophyte produces spores through meiosis, which are dispersed and develop into new gametophytes, completing the life cycle of mosses.

Pine trees, sunflowers, and ferns, on the other hand, are seed-producing plants that have a dominant sporophyte generation. The sporophyte generation is the most prominent phase in their life cycle, and the gametophyte generation is much smaller and dependent on the sporophyte for nutrition.

The gram-negative bacterium appearing purple after performing a gram stain is likely due to a mistake made during the staining process. Gram staining is a technique used to differentiate bacterial species based on their cell wall composition. Gram-negative bacteria have a thinner peptidoglycan layer and an outer membrane, which makes them resistant to the crystal violet stain used in the first step of the staining system. The counterstain, safranin, is then used to stain gram-negative bacteria pink.

However, if the decolorizing step is not done properly, the crystal violet stain may remain in the gram-negative bacteria, resulting in a false positive, and the bacteria will appear purple instead of pink. It is important to follow the proper steps and timing in the gram staining process to ensure accurate results.

Answer:

An important source of genetic variation comes from mutations. A mutation is a change in the DNA sequence of a gene. Though some mutations are harmful, most are not. A mutation may change a trait in a way that may even be helpful, such as enabling an organism to better adapt to its environment.

The simplest mutation is a point mutation. This occurs when one nucleotide base is substituted for another in a DNA sequence. The change can cause the wrong amino acid to be produced. In some cases, the change has little effect. In other cases, the incorrect amino acid can affect the structure or function of the protein being encoded.

Here’s an example of how this works. This sentence composed of three-letter words is similar to a DNA sequence made up of three-base sequences called codon Now, what happens if one letter is changed?

The sentence now has a different meaning! Notice that the change affects just one word. If this was a DNA sequence, a change in one codon might not cause problems.

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.
