Carbon 12 is the most common isotope of carbon with a mass number of 12. However, the average atomic mass of carbon found on the periodic table is more than 12 tons. This is because of the following reasons: The tom does not include the mass of electrons.

This is because electrons are much lighter than the other subatomic particles, and their mass is not considered in the calculation of the atomic mass of an element. Some carbon stores in uwe have an extra proto. Carbon 12 is the most abundant isotope of carbon and has six protons and six neutrons in its nucleus. However, some carbon atoms have an extra neutron or two, making them isotopes of carbon. The presence of these isotopes in nature accounts for the slightly higher atomic mass of carbon found on the periodic table.

Some Carbon atominature have more on. Some carbon atoms have more than six neutrons in their nucleus, making them heavier isotopes of carbon.

The important enzyme in Calvin cycle is ibulose bisphosphate carboxylase (RuBisCO).

The Calvin cycle is important because it performs chemical reactions by plants to fix carbon from CO2 into three-carbon sugars. Then, plants and creatures can transform these three-carbon compounds into amino acids, nucleotides, and more complex sugars like starches.

Reactions of photosynthesis that use the energy stored by the light-dependent reactions to form glucose and other carbohydrate molecules is called Calvin cycle. Carbon fixation occurs  During the first phase of the Calvin cycle.

The carbon dioxide combines with ribulose 1,5-bisphosphate to form two 3-phosphoglycerate molecules (3-PG) and the  enzyme that catalyzes this reaction is RuBisCO. It is the enzyme  that is responsible for photosynthetic carbon assimilation in catalyzing the reaction of CO2 with ribulose 1,5‐bisphosphate (RuBP) to form two molecules of d‐ phosphoglyceric acid (PGA).

In John Steinbeck's "Of Mice and Men," Lennie is compared to a bear and a dog, both of which are large, powerful animals that can be dangerous if they lose control.

In "Of Mice and Men," Lennie Small, one of the main characters, is frequently compared to animals, particularly a bear and a dog. Lennie's physical size and strength are reminiscent of a bear, while his loyalty and simple-mindedness are reminiscent of a dog. However, both bears and dogs can be dangerous if they lose control, just as Lennie's strength and lack of understanding can lead to unintended harm.

In the novel, Lennie's physical strength is a recurring theme. He is described as being "shapeless of face, with large, pale eyes with wide, sloping shoulders, and he walked heavily, dragging his feet a little, the way a bear drags his paws" (Chapter 1).

This description highlights Lennie's physical resemblance to a bear, emphasizing his size and strength. Throughout the novel, Lennie is portrayed as being able to perform feats of strength that are beyond the capabilities of the other characters, such as lifting bags of grain and breaking the necks of small animals.

Lennie's loyalty and simple-mindedness are also compared to that of a dog. He is described as being "like a terrier who doesn't want to bring his ball to its master" (Chapter 1) and "like a kid" (Chapter 3). These descriptions emphasize Lennie's desire to please and his lack of understanding of the consequences of his actions.

Lennie's behavior towards animals is particularly reminiscent of a dog, as he is gentle and affectionate towards them, but his lack of control can lead to unintentional harm, such as when he accidentally kills a puppy.

Answer:

defensive mutualism

Explanation:

took the quiz, got it right.

Due to cell specialization, the majority of genes in eukaryotes are individually regulated and have more complicated sequences.

Prokaryotes have operons, which are collections of genes that are controlled collectively. The regulation of gene expression in eukaryotes can occur on a variety of levels, and it is more difficult in multicellular organisms because of cell specialization. Then there are microRNAs, which through RNA interference can prevent the production of certain genes. Generic or common cells become specialized cells with specific functions through a process called cell specialization, also known as cell differentiation. Through cell differentiation, generic embryonic cells become specialized cells.

Arterial pressure is substantially higher than venous pressure. Option 3 is Correct.

The vascular pressure in a vein or the heart's atria is referred to as venous pressure. With typical readings of 5 mmHg in the right atrium and 8 mmHg in the left atrium, it is significantly lower than arterial pressure.  Because the arteries receive blood from the heart after contracting, as well as because of their contractile ability, blood pressure in the arteries is significantly higher than in the veins.

In comparison to veins, arteries have thicker tunica media, smoother muscle fibres, and more elastic tissue. Due to their close proximity to the heart's ventricle, the major arteries (such the aorta) have the highest blood pressure. as the small blood vessel divides. Option 3 is Correct.

The statement that is not true concerning enzymes is option d: "they can form covalent bonds with their substrates." Enzymes do not form covalent bonds with their substrates during the course of a reaction.

Enzymes act as catalysts, facilitating chemical reactions by lowering the activation energy required for the reaction to occur. They achieve this through several mechanisms, including options a, b, and c.

Enzymes do not require an input of energy from ATP for activation (option a). Instead, they utilize their own three-dimensional structure to facilitate reactions. Enzymes can change the shape of substrates (option b) by binding to them and inducing a conformational change that brings reactive groups together.

This helps increase the rate of a specific reaction. Additionally, enzymes can bring reactants together in the proper orientation (option c), allowing them to interact more efficiently and enhancing the likelihood of a chemical reaction.

Therefore, the correct statement is that enzymes do not form covalent bonds with their substrates, option d.

The most important process in improving the features of plants long used by humans as staple foods over human history are artificial selection.

Artificial selection has been the most significant process in improving the features of plants that have served as staple foods for humans throughout history. Artificial selection, also known as selective breeding, involves the deliberate selection and breeding of plants with desirable traits to produce offspring with enhanced characteristics.

Through careful selection and controlled breeding practices, humans have been able to modify plants' genetic makeup and cultivate varieties that are more productive, resistant to diseases, and better suited to specific environmental conditions.

Genetic engineering, while a more recent development, has also played a role in improving crop traits by directly manipulating the plants' DNA. However, over the course of human history, the practice of artificial selection has been the primary method employed to enhance the features of staple food plants.

By selecting and breeding plants with desired traits, humans have been able to create crop varieties that provide higher yields, improved nutritional content, and enhanced resistance to pests and diseases, contributing to the advancement of agriculture and food production.

In contrast, while natural selection, sexual selection, pesticide and herbicide application, and other processes may have influenced plant evolution, they have not been as significant or intentional in shaping the features of staple food plants as the artificial selection has been.
