Answer:
Nutrition In Human Beings. Nutrients are the substances in food that maintain the body and make it work. Most of what one eats is made up of carbohydrates, proteins, and fats. Nutrients needed in smaller amounts, but still vital, are vitamins and minerals.

Hope it's answer you plz mark as Brainlist
The human being has a heterotrophic nutrition. Nutrition is realised by digestion. Digestion can be either intracellular or extracellular. Intracellular digestion occurs for example when white blood cells consume pathogens or dead tissue. Extracellular digestion occurs in the digestive tract. Digestion can be either mechanical(chewing) or chemical(hydrolysis-a process in which for every broken bond a water molecule is added).
The main types of nutrients are:
Carbohydrates that are mainly used for energy. In the digestive tract there are different enzymes that hydrolyse the carbohydrates to monosaccharides.
Carbohydrate----(enzyme)--->monosaccharide
Proteins play an important structural and functional role in the body. There are specific enzymes that digest them. They are broked down to amino acids.
Protein-------(enzyme)---->amino acid
Lipids store energy. There are enzymes that break lipids down to fatty acids and glycerol.
Lipids----(enzyme)--->fatty acids+glycerol
Vitamins help the metabolism and are not chemically processed in the digestive tract nor are minerals or water.
Which macromolecule is made of only carbon, hydrogen, and oxygen and is used as short term energy storage for
building the structural components of living things?
A. lipid
B. protein
C. nucleic acid
D. carbohydrate
A macromolecule that is composed of only carbon, hydrogen, and oxygen and is specifically used as a short-term energy source for building the structural components of living things is Carbohydrates.
Carbohydrates are one of the biomolecules that are made up of only elements such as Hydrogen, Carbon, and Oxygen. Each molecule’s type has its unique specific function. Some significant functions of carbohydrates are mentioned as follows:
Carbohydrates are useful for different living organisms as an attainable energy source to activate various reactions in our cells. Living cells tend to modify their structures to enhance their function by combining carbohydrates with proteins and lipids. It helps in supporting the cell by providing a structure within the walls of the cells.Thus, we can conclude that the correct answer is carbohydrates and thus, option D is the correct answer.

what is the relationship between inertia and motion
Ally wants to reduce the amount of carbon dioxide in her local area. What are two different things that Ally could do to reduce the amount of carbon dioxide in the atmosphere? Explain how each would reduce the amount of carbon.
Answer:
1, Planting trees
2. Actions that reduce carbon dioxide emission
Explanation:
Ally can reduce the amount of carbon dioxide in the atmosphere in two ways
1. By planting trees or reforestation
Trees generally act as a sink for carbon through photosynthesis. Hence, planting more trees means that more carbon dioxide in the atmosphere will become fixed into the trees leading to the reduction of the gas in the atmosphere.
2. Reducing emission
To further reduce the amount of carbon dioxide in the atmosphere, the rate of emission of the gas has to be reduced. Actions such as the burning of vegetation and fossil fuels need to be reduced because they increase the emission of carbon dioxide gas into the atmosphere. The actions can be substituted for less or no carbon dioxide emitting alternatives.
When less carbon dioxide is emitted into the atmosphere and more is being fixed into trees, the overall concentration of the gas in the atmosphere will reduce greatly with time.
What happens when the atmosphere interacts with the biosphere?
Answer:
At the point when environment connects with biosphere they centers around on the sources and sinks of green house gases (GHGs) air toxins, specific issues, water and vitality between the world's surface and the climate. The biosphere influences the atmosphere.

How many daughter cells are made during mitosis? ______________ During meiosis? _____________ 2. In humans how many chromosomes will be in a daughter cell after mitosis? _____ After meiosis? ____ 3. What happens during interphase before both mitosis and meiosis can begin?
Answers and explanation:
Most of the cells in the human body are somatic cells and have 23 pairs of chromosomes (46 chromosomes in total) and are thus called 'diploid cells'. The only cells that have 23 single chromosomes are the gametes, which are haploid cells - the reason behind this is that gametes in females (ovum) need to be fertilized by the gametes present in males (sperm) to form a new being: the zygote.
Mitosis and meiosis are both processes in which the cells are divided, but they are quite different. In Mitosis, the somatic cells divide themselves to generate two daughter cells that are equal to the cell that has divided. In Meiosis, the diploid cells that generate the gametes, divide into four daughter cells, which will all have half of the chromosomes (the four of them will be haploid cells with 23 chromosomes each).
1. How many daughter cells are made during mitosis? 2.
During meiosis? 4.
2. In humans how many chromosomes will be in a daughter cell after mitosis? 46. After meiosis? 23.
3. What happens during interphase before both mitosis and meiosis can begin?
Interphase is the name given to the part of the cell cycle in which the cells are not dividing themselves. In this phase, cells spend most of their lives, and they use it to do things such as obtaining nutrients and metabolizing them so they can make use of them to carry on with their specific tasks, which vary depending on the type of the cell. In a very specific part of Interphase called the S phase, the cell duplicates its DNA - this leads to the cell having 2 copies of the same information, which will be important when cell division comes (in Mitosis, each daughter cell will get one complete copy; in Meiosis, each daughter cell will have half of a copy).
Which of the following is an example of adhesion in organisms?
a. capillary action of liquid in plant stems
b. release of sweat to reduce body heat
c. movement of ions to maintain homeostasis
d. pumping of blood through the circulatory system
Answer:
a. capillary action of liquid in plant stems
Explanation:
Vascular plants need to transport water from roots to stem and leaves. For this purpose, water molecules adhere to xylem cell walls (xylem is one of the two classes of transport tissues in higher plants). Adhesion, also known as capillary action, is a mechanism produced when water molecules cling to xylem cell walls. Thus, adhesion can be defined as a molecular mechanism caused by the attraction between molecules, in this case, between molecules of the xylem and water molecules.
Difference between annual and perennial plants any two please
Answer:
Annual plants live for one growing season and then die, while perennials regrow every spring. ... The difference, according to plant geneticist Siegbert Melzer and his team, comes down to two critical flower-inducing genes that, when turned off, can make an annual plant regrow every year.
Trevor examines some water from the open ocean and finds that it contains several single-celled and multi-celled organisms. What term should Trevor use to describe the organisms based on their method of locomotion? Trevor should use the term to describe the organisms on the basis of their ability to move in water. Every time I try to put Pelagos, I get it wrong.
Answer:
Mobility.
Explanation:
Mobility is the term used for all types of movement such as walking , running, swimming and flying etc. Mobility refer to the movement, those organisms which has the ability to move from one place to another is known as mobile organisms e.g lion, birds, tiger and humans etc, while on the other hand those organisms that are unable to move from place to place is called immobile organisms.
