Answering all 5 questions:

Answer 1: As shown in the picture- deer is one such biotic factor and water is an abiotic factor.

Answer 2: As an organism's survival, both biotic and abiotic play crucial parts in every organism's life. Abiotic factors are limited on this earth and with the growing population of organisms ( plants and animals), competing for getting basic things needs to become an edge for survival by parasitism, mutualism, and commensalism.

2 biotic factors like plants(food) and animals( meat) and 2 abiotic factors like soil and water- with these 2-2 biotic and abiotic factors, human beings as an organism compete with other human beings for survival.

Answer 3: Plants cannot move, however, from the germination of a seed to a fully grown-up tree, it requires space, sunlight, water, minerals, and air for which plants also compete with other trees and even with human beings for water consumption and space.

Answer 4: If animals living in arctic regions start experiencing global warming effects, they do three things: move, adapt or die. In adaptation, to the change in temperature, arctic animals may change their behavior and become less vulnerable to heat. They may also witness some body shape changes within themselves.

Answer 5: food chain is a chain of organisms where one organism acts as food for another organism to maintain the population of each organism. While food web is a collection of all food chains that exist in the ecosystem from an ant to a big elephant or a powerful lion.

Food chain and food web help in balancing the whole biodiversity of the environment.

The femur or thigh bone. It's the longest, strongest bone in your body. It's a critical part of your ability to stand and move. Your femur also supports lots of important muscles, tendons, ligaments and parts of your circulatory system.

Explanation:

Hope it helps! =D

The movement of the entire skeleton or skeletal elements utilizes the anchoring of muscles to attachment sites on the bones, which then serve as levers.

Muscles are anchored to tendon and fibrous connective tissue that attaches muscle to bone. Tendons may also attach muscles to structures such as the eyeball. A tendon serves to move the bone or structure.

Muscles attach to bones at locations called origins and Insertions. A skeletal muscle attaches to bone at two or more places. If the place is a bone that remains immobile for an action, the attachment is called an origin. When your muscle activates or bunches up, it pulls on the tendon. Tendons attach muscles to bones. The tendon pulls the bone and  make it move.

Mutation that did not affect the protein coded by a gene is silent point mutation .

Silent mutations generally occur when the shift of a single DNA nucleotide within a protein-coding portion of a gene does not disturb the sequence of amino acids that make up the gene's protein. Mutations that cause the modified codon to produce an amino acid with identical functionality are also classified as silent.

Silent mutation can some times be harmful it may cause pause during reading of genes .Many studies have also shown how silent mutation is responsible for many life threatening disease like breast cancer .

At a pH of 5, the concentration of ethanol is the greatest so alcoholic fermentation is taking place at a fastest rate.

This is referred to as power of hydrogen and it is the measure of the acidity or alkalinity of a substance. pH of 7 is referred to as being neutral while pH of 1-6.9 is regarded as being acidic.

Fermentation on the other hand is a chemical process which involves the breakdown of glucose anaerobically. This means in the absence of oxygen and the product is ethanol which is how various types of beer are made in industries.

The speed of both routes is 654.2 km/s and 461.78 km/s respectively.

Calculation:-

1 mile = 1.61 km

2,439 mile =  2,439×1.61 km

The properly sliced mature RNA transcript will be 500 bp long due to the presence of exons.  

Exons are the part of the genome that encode for the genetic information. These are present in a fully mature RNA as they are essential for the formation of protein. If a gene contains three exons with length 140, 230, and 130 bp, then the length of its mature RNA will be the sum total of all the exons only. Therefore the length is 500 bp.

The oxidation of pyruvate to acetyl CoA yields 1/3 carbon dioxide on glycolysis.

Glycolysis occurs in the cytoplasm and results in pyruvate. Pyruvate oxidation takes place in the mitochondrial matrix.

The following reaction results in the conversion of pyruvate to acetyl-CoA:

Pyruvate + NAD⁺ + CoA-SH ⇒ acetyl-CoA + NADH + CO₂

One molecule of pyruvate is converted into one molecule of carbon dioxide.

Also, two molecules of pyruvate are converted into two molecules of carbon dioxide (as glucose on glycolysis yields 2 molecules of pyruvate).

Acetyl-CoA also contributes to the citric acid cycle and generates two molecules of CO2.

Pyruvate thus generates a total of 3 molecules of CO2, whereas glucose generates 6 molecules of CO2 (as glucose on glycolysis yields 2 molecules of pyruvate)

Therefore, we get that pyruvate produces total 3 molecules of CO₂ and glucose produces 6 molecules of CO₂ (as glucose on glycolysis yields 2 molecules of pyruvate).

All living organisms need the strength to grow and reproduce, maintain their systems and respond to their environments. Metabolism is the set of life-sustaining chemical approaches that permits organisms to transform the chemical power stored in molecules into power that can be used for mobile tactics.

This energy comes from the food we eat. Our body digests the food we eat by mixing it with the fluids (acids and enzymes) inside the stomach. When the stomach digests food, the carbohydrates it contains (sugar and starch) are broken down into another type of sugar called glucose.
