Answer: Nitrogen and oxygen are by far the most common; dry air is composed of about 78% nitrogen (N2) and about 21% oxygen (O2). Argon, carbon dioxide (CO2), and many other gases are also present in much lower amounts; each makes up less than 1% of the atmosphere's mixture of gases.
Explanation:
In addition to oxygen, the gases that make up the largest percentage of Earth's atmosphere may significantly include nitrogen, argon, carbon dioxide, etc.
Why oxygen is essentially required for living organisms?Oxygen is essentially required for living organisms because it helps organisms grow, reproduce, and turn food into energy. Humans get the oxygen they need by breathing through their noses and mouth into their lungs.
Oxygen gives our cells the capability in order to break down food in order to get the energy they need to survive. Oxygen consists of 21% of the total earth's atmosphere along with 78% of the nitrogen and 1% of all rest of the gases like argon, carbon dioxide, etc.

Hey guys what’s the best way to memorize a science fair project? I have to present one tomorrow and I’m worried
practice with people (parents, friends, siblings) and ask them to ask questions during it so you can learn how to keep focus and memorization, or practice in front of stuffed animals. read it out loud on recording, then practice saying it with the recording without the words in front of you. you'll do great! :)
Answer:
Just present to someone you know a couple of times but try to memorize it while speaking. You can also write what your going to say on some index cards or something just in case you forget something. Just stay calm and take deep breaths when needed
Explanation:
Sohan was a very active and a social child. He used to come forward for anybody help. One day he attended a blood donation camp and was ready to donate blood, but his blood test was done and he was HIV+ve. Therefore he was very upset and lost his interest in all activities and remained absent from school for long time. Rajiv, his friend met him and counselled him.He (Sohan) was back at school. a) What sense of responsibility did Rajiv show? b) A HIV+ve person should be isolated. Do you agree with this statement. Justify your answer?
Explanation:
(a) After vis friends comforted him he went back to school.
(b) No. HIV can only be caught by another person of they come in contact with your blood or through sexual intercourse. So it is not possible for others to become infected if they didn't come in contact with the person's blood or have unprotected intercourse. There is no reason for a HIV+ve person to isolate themself from the outside world. They are people just as we are but they only have something that can cause them to be really sick.
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.

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.
Do either of your diseases in part A have the same pattern of inheritance as the model colorblindness mutation you made?How do you know?
Answer:
Autosomal dominant pattern.
Explanation:
If the pattern of inheritance is same in the disease just like the model of colorblindness mutation so we can say that the disease has autosomal dominant pattern because the colorblindness mutation also occur due to the autosomal dominant pattern. Sometimes the disease is also inherited from their parents through genetically. So both diseases and the model colorblindness mutation are considered same if both have the same pattern of inheritance.
describe the effect of magnesium deficiency on the transport of sucrose out of the leaves and the sucrose concentration out of the leaf
Answer:
The impact of diminishing the convergence of magnesium salt on the development of S.polyrhiza is because the low mg accessibility keeps an eye on troublesome sucrose exportation, making leaves hold sucrose three to multiple times more than the leaves of plants that get Mg in satisfactory inventory, showing that the inadequacy of this supplement causes extreme hindrance of sucrose transport.

Answer:
adherence of phagocytes to the lining of blood vessels
Explanation:
The correct answer for the medical/biological definition of margination would be the adherence of phagocytes to the lining of blood vessels.
Margination is a process that takes place when injuries occur in complex animals. During the early phase of inflammation of the injury site, the blood capillaries dilate and the white blood cells (phagocytes and leukocytes) adhere to the endothelial cells of blood vessels.

How does the structure of DNA direct the formation of proteins?
Answer: During the process of transcription, the information stored in a gene's DNA is transferred to a similar molecule called RNA (ribonucleic acid) in the cell nucleus. ... A type of RNA called transfer RNA (tRNA) assembles the protein, one amino acid at a time.
The sequence of nucleotides of DNA directs the formation of the structure of proteins. The information stored in the DNA is transferred to the RNA by transcription and the RNA forms the proteins.
What is the process of protein formation?The process of the creation of protein molecules is called protein biosynthesis. Amino acid synthesis, transcription, translation, and post-translational events are the steps that are involved in protein synthesis. In the case of amino acid synthesis, a set of biochemical processes happen and they produce amino acids from various carbon sources like glucose.
In the case of biological systems, protein synthesis happens inside the cell. In the case of prokaryotes, it occurs in the cytoplasm. In eukaryotes, it happens in part in the nucleus and partly in the cytoplasm.
The transcript is formed in the nucleus and leaves the nucleus to reache the ribosomes and it is translated there and forms a protein molecule that has a specific sequence of amino acids.
The creation of proteins by cells uses DNA, RNA, and various enzymes. Usually, it includes the events like transcription, translation, and post-translational events. These are protein folding, modifications, and proteolysis.
Therefore, the sequence of nucleotides of DNA directs the formation of the structure of proteins. The information stored in the DNA is transferred to the RNA by transcription and the RNA forms the proteins.

describe about nutrition in human being
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.
Explanation:
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.

-Worldwide sea level increased
-river plains drowned
Explanation
Glaciers are large blocks of ice and with all the ice melting the water levels rose worldwide. (Correct Answer)
When sea levels rose it caused river plains to be flooded. (Correct Answer)
Glaciers are made from freshwater so when they melt the salinity in estuaries does change. (Not a correct Answer)
Erosion definitely affected river valleys. Alpine glaciers create valleys and even help erode valleys. With Alpine glaciers melting this slows the process of that erosion and with them melting the river valleys will eventually flood. (Not a correct Answer)

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).
