How does a calorie on a food label relate to a calorie that is produced in cellular respiration?? Please help

Answers

Answer:

There are 1000 calories in 1 Calorie (notice the difference in the capital C) on our food labels the Calories are given. Cellular respiration ; the process that releases energy by breaking down glucose and other food molecules in the presence of oxygen, begins with a chemical pathway called glycolysis

Explanation:

Hope this helped, Have an amazing, spooky Halloween!!

The relationship between the calorie on a food label with the calorie produced in a cellular respiration is ;

I Calorie on a food label is equivalent to 1000 calories produced in cellular respiration

When labeling food to indicate the nutrients contained in the food ( especially canned foods ) the amount of calories contained in the food is indicated and for every Calorie ( 1 calorie ) indicated on the label represents an equivalent of 1000 calories found in cellular respiration.

Hence we can conclude that 1 Calorie indicated on a food label is an equivalent of 1000 calories produced in a cellular respiration.

Which of the following is NOT true about matter in the biosphere?
a) Matter is transferred in one direction through the biosphere. b) Biogeochemical cycles transform and reuse molecules. c) The total amount of matter decreases over time. d) Human activity does not affect the movement of matter

Answers

Answer:

c) The total amount of matter decreases over time.

Explanation:

The statement 'the total amount of matter decreases over time' is NOT true about the matter in the biosphere (Option c).

The biosphere refers to the total of all ecosystems of the Earth.

The biosphere can be defined as a closed system in terms of matter because matter does not enter or exit.

In the biosphere, the total amount of matter remains constant over time, whereas the total amount of energy decreases over time.

This energy is lost in the form of heat when it spreads from the Earth's surface and outward into space.

In conclusion, the statement 'the total amount of matter decreases over time' is NOT true about the matter in the biosphere (Option c).

As you have observed, animal hairs usually have a large medulla composed of air-filled compartments. These air-filled compartments are present for a reason and can actually help hair do its job better. Describe one reason that might explain why having a hair made of air filled compartments could be helpful to an animal.
PLEASE HELP

Answers

Answer:

to provide insulation

Explanation:

The medullary index is the proportion of the diameter of the hair medulla in regard to the diameter of the entire hair: The equation to calculate the medullary index is medulla diameter/hair diameter. In animals, the hair medulla is generally thicker compared to humans (medullary index approximately 0.5 and 0.33, respectively). The thicker the diameter of the hair medulla, the better is the insulation.

a. I y II son correctas

b. III y IV son correctas

c. II, III y IV son correctas

d. I, II y III son correctas.

Answers

Respuesta:

La respuesta correcta es la C, ya que II, III y IV son correctas.

Explicación:

Nuestro sistema inmunológico nos defiende de agentes patógenos que pueden enfermarnos, y está compuesto por dos tipos distintos de inmunidades: la inmunidad innata y la inmunidad adaptativa.

La inmunidad innata es aquella que reacciona primero cuando se presenta una amenaza, atacando a los patógenos de manera inespecífica gracias a mecanismos que ya existían antes de que se desarrolle la infección. Cuando se trata de inmunidad innata, nuestras principales barreras de defensa son la piel y las mucosas, y las células de la respuesta inmune de mayor relevancia son los neutrófilos, entre otras.

Por el contrario, la inmunidad adaptativa, es de respuesta tardía y puede actuar de maneras diferentes dependiendo de cuál sea el patógeno invasor. Hay dos tipos de inmunidad adaptativa, la humoral y la celular. De la inmunidad humoral participan principalmente los linfocitos B, que fabrican anticuerpos específicos; mientras que la inmunidad celular es llevada a cabo por linfocitos T. La ventaja que tiene la inmunidad adaptativa en comparación con la innata es que es específica, diversa, más eficaz, y POSEE MEMORIA.

Las células de la inmunidad adaptativa presentan la capacidad de "recordar" cómo el cuerpo actuó ante una amenaza en el pasado para poder llevar a cabo un plan mucho más eficaz. Esta es la razón por la que las vacunas funcionan: porque se le inyecta a los individuos una versión débil del patógeno (por ejemplo, del virus que causa la varicela) para que el cuerpo "aprenda" a vencerlo para cuando se encuentre con ese microorganismo en un futuro.

Given that almost all organisms obtain energy from food by the process of cellular respiration, which is the most likely explanation for what prevents Earth from running out of oxygen?

Answers

Answer:

Oxygen cycles keeps the flow of oxygen at a constant rate.

Explanation:

The oxygen constitutes about 20% of the gaseous components in the atmosphere and it's being renewed continuously by the various microorganism and primary producers as green plants that use photosynthesis and converts the sunlight and carbon dioxide to water and releases oxygen. Oxygen cycle makes life possible as most of the elements are combined with oxygen in some way or another and are found on the lithosphere, hydrosphere, and atmosphere even biosphere hence its is present insufficient amounts.

Answer:

A.)     The net effects of the reactions of photosynthesis and cellular respiration are the opposite of one another, therefore the products of one are the reactants of the other, creating a cycle.

Answers

Explanation:

·have cell wall

cell wall is present in plant and fungi due to protection

but not in animals due to locomotion mode of life

Fungi have cell walls characteristic which fungi share with plants but not animals, hence option C is correct.

What are the characteristics of fungi?

When compared to animals, fungi need prepared organic substances for energy because they are heterotrophic organisms without chloroplasts.

Fungi are eukaryotic organisms, just like plants, and have nuclei in each of their cells. Like plants, fungi lack a cell wall and vacuoles, however, they do have a material called chitin in their cell walls that plants do not. In numerous important respects, fungi are also similar to animals.

Eukaryotic, non-vascular, immobile, heterotrophic creatures are fungi. They could be filamentous or unicellular and spread spores to reproduce. The phenomena of generational alternation are seen in fungi.

Therefore, in comparison to plants, fungi have vacuoles and a cell wall.

As lactose approaches the active site of lactase, as shown in the image, which of the following occurs first?

The lactose molecule is broken into glucose and galactose.
Lactase shifts to its lowest free energy level to allow lactose to enter the active site.
Lactose creates a microenvironment as it approaches lactase to promote binding.
Temporary bonding occurs between the active site and the substrate, causing a conformational change.

Answers

Answer:

There is no image attachment, however, this question can be answered based on general understanding of enzymes. The answer is:

Temporary bonding occurs between the active site and the substrate, causing a conformational change.

Explanation:

Enzymes are proteinous molecules that acts as catalyst in biochemical reactions by speeding up the rate of reactions. According to this question, lactase is an enzyme that acts on lactose sugar and breaks it down into its monomeric unit (glucose and galactose).

All enzymes possess an active site, with which they bind to their substrate. In this question, the lactose (substrate) approaches the active site of lactase (enzyme), what occurs first is that a temporary bonding occurs between the active site and the substrate, causing a conformational change in the shape of the enzyme.

Most mutations that cause cancer occur within body cells, and body cell mutations are not inherited. If cancer is not inherited, why does cancer statically appear to run in families?

Family members have a widely varied genetic make-up that can be affected by specific mutagens.
Family members share the contagious mutagens that can be passed by close exposure.

Answers

Answer:

Family members have a similar genetic make-up that may make them predisposed to cancer.

Explanation:

Variation in certain genes can increase the risk of developing certain cancers. This is why certain cancers run in families. There are lots of examples where the risk factor is small, but in some cases, the risk factor is very large.

For example, mutations in BRCA1 are very highly linked to the risk of breast cancer. As a result, many women with mutations in this gene opt to get a mastectomy to reduce their chances of developing breast cancer.

He cant have my shoes, he stole my guitar! Erkans eyes looked impudent beneath his dark brow as his cheeks reddened in fury. His gray-whiskered lips trembled as his hand gripped tightly around the nurses wrist. The nurse carefully but firmly freed himself from Erkans grasp. He then turned to the caregiver who was assisting him, smiled, and said calmly, Go get Michelle.Michelle was scanning boxes of gauze bandages and stacking them onto a shelf in the storeroom when the caregiver came in and announced, Phillips trying to get Erkan to take a shower and he needs your help. Michelle rushed out of the store room and down the hall to Erkans room.This was the last week of Michelles internship. It was her junior year, and the internship was part of her Workplace and Consumer Education class. At first she wanted to intern at her dads gas station, but her teacher told her she needed to branch out and signed Michelle up at the Oakcourt Nursing Home, only 15 minutes away from her house.Wearing a Pittsburgh Steelers sweatshirt and jeans, with dark curls pushed back in a hair clip, Michelle stood out from the crowd of nurses and caregivers in white pants and polo shirts who were standing huddled in the doorway of Erkans room. She moved past them and rushed to Erkans side. As soon as he saw her, Erkans face brightened and he stopped looking like a stricken animal and instead looked like someone who recognized a dear old friend.He cant have them, Michelle. I sold them at the corner, Erkan shouted, pushing his way to Michelle. He stole my guitar, he whispered.I know, Erkan, but he was only trying to help you get some money to pay for your trip. Michelle had been frightened by a lot of the residents of the nursing home when she first started the beginning of the semester. Many of them were incoherent and loud, and some could be very aggressive and scary. Erkan often pushed or kicked and ranted. Michelle had started to regret this internship, and she even avoided going near Erkans room whenever possible. He lives in his own world, Philip, the managing nurse, explained to Michelle after her first encounter with Erkans temper.Still, Michelle had been curious, and she felt sorry that Erkan had a bad reputation among the staff. She too had felt like everyone mistrusted herespecially at the nursing home where she was so much younger than the rest of the staffso she understood how he must feel. Besides, he was the only person in the whole place with skin nearly as dark as hers.Over time, she noticed patterns in Erkans rants: He would sometimes mention his guitar and his father and the city of Diyarbakir, which she learned is in Turkey. So she decided that the next time she brought supplies to his room, instead of avoiding Erkan, she would play along with whatever he said. If he lived in his own world, then she would try to join him there. Bit by bit, she discovered that he had immigrated to the United States from Turkey when he was very young. His father had saved as much money as possible to pay for his journey, but he needed to sell Erkans guitar to help cover the cost. Erkan had moved in with his aunts family in Scranton, Pennsylvania, and finished school there. Eventually he got married, had children of his own, and worked for years signing Turkish singers to a small record label. But hed never quite felt at home in the United States.I know he sold your guitar, but you told me yourself he just wants whats best for you, Michelle said, while Philip and the caregiver looked on in amazement as Erkan settled into an armchair. Now why dont you listen to Philip, take your shoes off, and have a shower?For you, Michelle, Ill do it.You can feel out of place in a country, in the place where you live, or even in your own head, Michelle thought.
