commensalism:only one specie benefits why the other is neither helped not harmed. eg is the remora fish are very bony and have a dorsal fin that acts like a suction cup the remora fish gets a meal while the host gets nothing. selfish, sure but neither gets hurt

parasitism:one organism(the parasite)gains while the other(the host) suffers the deer thick is a parasite it attaches to a warm-blooded animal and feed on its blood. the thick benefits from the animal blood and unfortunately, the animal suffers from the loss of blood and nutrients and may get sick

Reconoce la ciencia indispensable para la vida del ser humano para dar explicación a fenómenos de la naturaleza

Answers

Answer:

La ciencia es indispensable porque permite comprender cuales son las fuerzas y los mecanismos que dan lugar a los fenómenos naturales tal y como los conocemos

Explanation:

Un fenómeno natural puede ser definido como un evento y/o proceso que se produce en el entorno natural y que puede ser percibido por algunos de los sentidos que posee el ser humano (es decir, vista, olfato, gusto, oído y tacto). La ciencia utiliza un método estandarizado (el método científico) el cual permite desentrañar cuales son las fuerzas que rigen los fenómenos naturales. De este modo, la ciencia es una herramienta indispensable para comprender cómo nacen y se desarrollan las pautas del mundo natural. Los avances científicos derivados de la aplicación del método científico resultan fundamentales porque de ellos depende en gran medida el desarrollo de nuevas tecnologías y procesos con el objetivo de mejorar la calidad de vida del ser humano, como así también el desarrollo de metodologías para preservar el entorno natural que nos rodea.

D. whipping cream.

Answers

Answer:

whipping cream

Explanation:

d. whipping cream

Among the following whipping cream is not a cultured dairy product. So the correct option is D.

What are cultured dairy products?

The technology required to create cultured dairy products on an industrial or commercial scale was developed in the late 19th century along with microbiological and nutritional sciences.

Warm raw milk from cows, sheep, goats, camels, or horses was naturally preserved by common strains of Streptococcus and Lactobacillus bacteria in ancient times, leading to the creation of fermented milk. By mixing in a little amount of the previous batch, the "cultures" were created.

These non-toxic lactic acid makers worked well to control spoilage and harmful organisms, allowing fresh milk to be kept for a few days or weeks without refrigeration. As people traveled, cultured goods gradually gained favourites with many ethnic groups and were spread around the world.

Therefore, the correct option is D.

Why is it better to get calories from nutrient-dense foods rather than from foods that lack nutrition? Diagram the passage of food through the digestive system. Label the organs involved in digestion and absorption and identify the sites where carbohydrates, proteins, and fats are digested. For each of the following foods, choose the one that’s more nutrient-dense. a. Low-fat popcorn or buttered crackers b. Macaroni and cheese or plain pasta c. Celery sticks or fresh fruit salad d. A slice of cheese pizza or a double cheeseburger e. Oatmeal with banana and raisins or cornflakes with milk Calculate the number of calories in each of the following foods. a. A slice of whole-wheat bread with 8 grams of carbohydrates b. 2 ounces of cheddar cheese with 6 grams of fat c. A serving of grilled chicken with 10 grams of protein

Answers

Answer:

Foods that are nutrient-dense give your body more than just calories; nutrient-dense foods provide the body with essential vitamins and minerals, whereas foods that aren’t nutrient-dense give the body only calories.

The body accesses nutrients through digestion, which begins in the mouth. Saliva and chewing break down the food. The esophagus empties into the stomach where protein is digested. Fat, carbohydrates, and leftover proteins are digested in the small intestine. The colon helps to absorb fluid. The pancreas, gallbladder, kidneys, and liver are also involved in digestion.

a. Low-fat popcorn—Crackers are high in fat.

b. Macaroni and cheese—The cheese does have more fat but offers protein,

calcium, vitamins A and D, and other nutrients.

c. Fruit salad—It contains more vitamins and minerals than celery alone.

d. Pizza—It probably contains less fat; the sauce has a small amount of vitamins.

e. Oatmeal—It contains more fiber, probably less fat, and more vitamins and

minerals with fruit.

a. Carbs have 4 calories per gram, so 4*8

32 calories.

b. Fat has 9 calories per gram, so 9*6

54 calories.

c. Protein has 4 calories per gram, so 4*10

40 calories.
