Excretion is a process in which metabolic waste is eliminated from an organism. In vertebrates this is primarily carried out by the lungs, kidneys, and skin. This is in contrast with secretion, where the substance may have specific tasks after leaving the cell. Excretion is an essential process in all forms of life. 

In simple terms, the process of eliminating or expelling waste matter.

b)They provide energy statements are NOT true of micro nutrients

Do micronutrients control bodily functions?

Every single micronutrient is crucial for the health of your body's systems. Getting enough of the various vitamins and minerals is essential for good health and could even aid in the prevention of disease.

This is due to the fact that micronutrients are involved in almost every bodily process.

One of the most important vitamin categories that your body need are micronutrients. They contain minerals and vitamins. The creation of energy, immune system health, blood coagulation, and other processes all depend on vitamins.

In the meanwhile, minerals are crucial for a number of functions, including growth, bone health, fluid balance, and others.

Answer:

Medulla.

Explanation:

The primary role of the medulla is regulating our involuntary functions that keeps us alive such as breathing, swallowing and heart rate. As part of the brain stem, it also helps transfer neural messages to and from the brain and spinal cord. It is located at the junction of the spinal cord and brain.

Hope this helps!! Brainliest?? Anyways have a great day!! :))

The respiratory center is medulla oblongata. It is involved in minute to minute control breathing.

Brain stem is made up of pons and the medulla oblongata.  

The apneustic and  the pnuemotaxic  centers of pons work together to  just control rate of  the breathing.  In that the medulla just  sends the  signals to muscles that just  initiate the  inspiration and  the expiration and just  controls the  nonrespiratory  in the air movement of the  reflexes like coughing and sneezing.

The cerebellum is  well known to just  be the  part of neuronal circuitry  that is just activated in the respiratory challenges that are  such as  the hunger for  the air but are not been made to be involved in control of  the spontaneous and the  unobstructed breathing .

Answer:

I thinks its A but not 100%

Explanation:

Answer:

If 0.9% NaCl were isotonic to a cell then anything greater than 0.9% would be hypertonic. A hypertonic solution is one which has a greater concentration of dissolved solutes while an isotonic one has a similar concentration of solutes.

Explanation:

If a 0.9 % salt solution is isotonic to an animal cell, then a hypertonic solution would be 1.0%. Thus, the correct option for this question is D.

A hypertonic solution may be defined as a type of solution that significantly has lower osmotic pressure than another solution to which it is compared. If the surrounding solution has a higher solute concentration compared to inside the cell, it represents a hypertonic solution.

According to the context of this question, if a 0.9 % salt solution is isotonic to an animal cell, then anything greater than 0.9% would be hypertonic. So, all the options except for 1.0% are lesser than or equal to 0.9%.

Therefore, if a 0.9 % salt solution is isotonic to an animal cell, then a hypertonic solution would be 1.0%. Thus, the correct option for this question is D.

Explanation:

The potato, bacteria and a human is alike in the way that they all are made up of cells. The correct option is B.

Cells are the fundamental cornerstones of all life. Gazillions of cells make up the human body.

They support the body's framework, absorb nutrients from food, convert those calories into energy, and perform specialized functions.

The cell, first discovered by Robert Hooke in 1665, has a rich and interesting history that has led to many of today's scientific advances.

Cell theory is a biological theory first proposed in the mid-nineteenth century that states that living organisms are made up of cells, that cells are the basic structural/organizational unit of all organisms, and that all cells originate from pre-existing cells.

Thus, the correct option is B.

phosophlipids containing a phosophate and 2 fatty acid chains connected by a glycerol molecule.

Explanation:

Phosophlipids containing the phosophate and two fatty acid chains connected by a glycerol molecule.

Lipid has been defined as an organic compound which has been unable to dissolve in the water. The example of lipids are oils, waxes, hormones, and fats. The main function of the lipid is to just maintain the structure as well as components of cell membranes, storage of site of energy, and important molecule of signaling that utilised in the process of signalling.

Full form of the RNA could be ribonucleic acid and it is a nucleic acid which has been found in almost all cells that are said to be living and RNA is mostly similar to the DNA but there is a difference between RNA as well as  DNA and the difference is that the RNA is single stranded but DNA is double stranded or its structure.

The RNA's backbone has been made up of phosphate group that is arranged in alternating form and the sugar known as ribose other than the deoxyribose which is  present in DNA. There are four bases found  in the RNA and these are adenine, uracil, guanine, and cytosine.

Explanation:

Answer:

TO TEST SUPPLY OF WATER QUALITY OF THE LOCALITY Excessively high and low pHs can be detrimental for the use of water. High pH causes a bitter taste, and water pipes.

Alkaline water turns red litmus paper blue. Acidic water turns blue litmus paper crimson. Pure or neutral water won't modify the litmus paper's color.Therefore, it can be used to test the quality of the drinking water.

A quantity that expresses the degree to which a substance or solution is acidic or basic. On a scale that ranges from 0 to 14, pH is measured. A pH value of 7 is considered neutral on this scale, which indicates that the substance in question is neither acidic nor basic. If the pH value is lower than 7, the substance in question is more acidic, and if the pH value is higher than 7, it indicates that the substance in question is more basic.

It is recommended that you consume water that is neither overly acidic nor overly alkaline, as well as water that is both clean and pure. The Environmental Protection Agency of the United States suggests that the pH level of drinking water should fall somewhere in the range of 6.5 to 8.5. The pH reading of the vast majority of ground and surface water should fall somewhere within this range.

Answer: Venn diagram of exocytosis , diffusion , endocytosis , osmosis is

described below.

Explanation:

Exocytosis: refers to the  process by which the contents of a cell are released to the exterior environment  through fusion of the vacuole membrane with the cell membrane.

Endocytosis: refers to the process in which cells take the material from outside the cell by taking in the vesicle. These materials serve as nutrients and pathogens which help cell to fight against foreign diseases.

The common thing these two process have among them is

Diffusion: It is the process of movement of molecules from through a

semipermeable membrane from the region of higher concentration to lower concentration.

Osmosis: The movement of water molecules from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules, through a cell's fractionally  permeable membrane.
