Why is the percentage of food eaten a good number to use?explain

Answers

To understand that you have to balance each food you intake in your body; Balancing your food is not only used to make you stay fit but it can enhance your mental and physical health.  Nutrition is vital for your body and all of its systems to function properly, by having good nutrition it will help you maintain a healthy weight, reduce body fat, provide your body with energy, promote good sleep and generally make you feel better. 

With the use of proper diet, you will go on to your everyday routine without feeling uncomfortable. Eating a diet rich in some vegetables and fruits as part of an overall healthy diet may protect against certain types of cancers. Diets rich in foods containing fiber, such as some vegetables and fruits, may reduce the risk of heart disease, obesity, and type-2 diabetes.

Final answer:

The percentage of food eaten provides valuable insights into energy conversion, nutrition, and socio-economic trends. It details how much of our food energy is converted into work, thermal energy, or stored fat, aids in making healthy food decisions, and reflects socio-economic shifts in food consumption.

Explanation:

The percentage of food eaten is an important number to use as it helps us understand the energy conversion and nutritional value of what we consume. It is a ratio that reveals that very little of the energy released in the consumption of food is used to do work. In fact, less than 10% of our food energy intake is used to do work while more than 90% gets converted to thermal energy or stored as chemical energy in fat. Moreover, knowing the percentage can be beneficial when making healthy food choices. Foods high in fiber and proteins are considered healthier as their nutrient density is high.

Furthermore, such information contributes valuable insights into socio-economic trends. For example, as income rises, people demand more calories from fats and proteins and fewer from carbohydrates. This has implications for global food production, obesity rates, and environmental consequences. Thus, the percentage of food eaten serves as a significant figure in understanding individual and community health, and global food economics.

Explain how flowering and non flowering plants are classified into major groups

Answers

Classify flowering and nonflowering plants into major groups such as those that produce seeds, or those like ferns and mosses that produce spores, according to their physical characteristics.

Hope this helped. 

Plants are classified into non-vascular, vascular, gymnosperms, and angiosperms. Flowering plants (angiosperms) are divided into monocots and dicots, with details about their life cycle and structure. Non-flowering plants (gymnosperms) do not produce flowers but have seeds.

Plants are classified into major groups based on their characteristics and reproductive structures. Here is how flowering and non-flowering plants are classified:

Classifications of Plants

Seedless Non-Vascular Plants: These include bryophytes like mosses and liverworts. They do not have vascular tissues and reproduce via spores.Seedless Vascular Plants: These include ferns and horsetails, which have vascular tissues but reproduce via spores rather than seeds.Gymnosperms: Non-flowering plants that produce seeds not enclosed in an ovary. Examples include conifers like pine trees.Angiosperms: Flowering plants that produce seeds enclosed within an ovary. Angiosperms are classified further into monocots and dicots.

Groups Within Angiosperms

Monocots: These plants form a single cotyledon (seed leaf). Examples include grasses, lilies, and irises. They typically have parallel leaf venation and floral parts in multiples of three.Dicots: These plants form two cotyledons. Examples include roses, sunflowers, and oak trees. They typically have net-like leaf venation and floral parts in multiples of four or five.Basal Angiosperms: These are primitive flowering plants that diverge early from other angiosperms. Examples include magnolias and water lilies.

Answers

I want to say A. but go listen to the cells rap to find out hope i helped plz give me brainliest answer

Mitochondria releases energy stored in food. Correct option is A.

Mitochondria are the cell's organelles responsible for releasing energy stored in food. They are often referred to as the "powerhouses" of the cell. Through a process called cellular respiration, mitochondria convert nutrients from food, such as glucose, into usable energy in the form of adenosine triphosphate (ATP). This energy is essential for various cellular activities and functions. Mitochondria are found in most eukaryotic cells, including animal and plant cells.

The primary function of mitochondria is to generate energy in the form of ATP through a process called cellular respiration. This process involves breaking down organic molecules, such as glucose, obtained from food to release energy. Mitochondria act as the site for several interconnected reactions that occur in different stages: glycolysis, the citric acid cycle (also known as the Krebs cycle), and the electron transport chain.

What are the disadvantages of a flatworms digestive system having only one opening?

Answers

The main disadvantage of a digestive system like this is that there is only one opening where the food enters and leaves. Therefore the organism, in our case,  the flatworm, must wait for the food to be digested and excreted through the opening in order to be able to eat again.
I  think the answer is that they cannot eat continuously. Due to the fact that flat worms have on opening, they will have to excrete using the same hole they eat from. This digestive system is common in simplest invertebrates in a gastrovascular cavity. It is also called an incomplete digestive system.

Which level of organization in the classification system is directly above the class level?
Domain
Family
Kingdom
Phylum

Answers

Answer:

Phylum

Explanation:

In the biological classification system, categories are used to group organisms according to their similarities. The basic category is species, which is defined as similar beings who are able to reproduce naturally and generate fertile descendants.

Animals of the same species are grouped into another category, the genus. All who belong to the same genre are grouped into families, which are grouped into orders, which in turn come together in classes, assembled in phyla, and finally we have the kingdoms. Kingdoms are therefore the last category in the hierarchy and subdivided into the most basic category. So we have:

Kingdom ⇒ Phylum ⇒ Class ⇒ Order ⇒ Family ⇒ Gender ⇒ Species

From this we can conclude that the level of organization in the classification system that is directly above the level of "class" is the "phylum".

Answer: Kingdom

Explanation: In this system of classification, kingdom is always ranked the highest followed by division, class, order, family, genus, and species.

Alana's diet contained 2150 kcal, with grams of protein (is this plenty for her?), 360 grams of carbohydrate, answers

Answers

I need to know this too!

Final answer:

Alana's protein intake is adequate if it ranges from 54 to 161 grams for a 2150 kcal diet, aligning with the AMDR of 10 to 30 percent of caloric intake. Her carbohydrate intake is slightly above the AMDR recommendation, which suggests a range of 242 to 349 grams for her caloric level. It's critical to personalize dietary recommendations based on individual health goals and activity levels.

Explanation:

The question seeks to evaluate if 2150 kcal with an unspecified amount of protein is sufficient for Alana's dietary needs. To determine the adequacy of protein intake, we refer to recommended dietary guidelines. The Acceptable Macronutrient Distribution Range (AMDR) for protein is 10 to 30 percent of daily calories. Using the higher end of this range for active individuals (such as endurance athletes), and assuming Alana falls into this category, an intake of 93 to 108 grams of protein would be appropriate on a 3000-kilocalorie diet, making up approximately 12 to 14 percent of daily calories. If Alana's diet contains 2150 kcal, approximately 54 to 161 grams of protein would align with the AMDR, based on 10 to 30 percent of her caloric intake.

For carbohydrates, the AMDR is 45 to 65 percent of daily calories, equating to roughly 242 to 349 grams for a 2150-kilocalorie diet. Alana's current intake of 360 grams of carbohydrate slightly exceeds this range, suggesting that while her carbohydrate intake may be sufficient or somewhat high, it is crucial to emphasize carbohydrates high in fiber for the majority of intake.

To assess the overall balance of Alana's diet, it's essential to consider her specific health goals, activity levels, and any dietary restrictions she may have. Consulting a dietician or nutritionist would provide personalized guidance.

Competitive ______ occurs when the competing species is no longer present.

A. exclusion
B. release
C. expulsion
D. none of the above

Answers

Competitive exclusion occurs when the competing species is no longer present.

The correct answer is B. release

Explanation:

In ecosystems, competition occurs as different organisms or species need the same limited resources such as water, territory, food or shelter and therefore compete for it, this includes competition within species and also between them. This type of interaction often leads to the disappearance of one of the organism or species interacting, which is regulated by the competitive exclusion principle that states to species competing cannot coexist. Additionally, once one of the competing species is no longer present competitive release occurs, this implies the competition ends and the remaining species can access the resources more fully. According to this, competitive release occurs when the competing species is no longer present.
