Answer:

The preceding section reviewed the major metabolic reactions by which the cell obtains and stores energy in the form of ATP. This metabolic energy is then used to accomplish various tasks, including the synthesis of macromolecules and other cell constituents. Thus, energy derived from the breakdown of organic molecules (catabolism) is used to drive the synthesis of other required components of the cell. Most catabolic pathways involve the oxidation of organic molecules coupled to the generation of both energy (ATP) and reducing power (NADH). In contrast, biosynthetic (anabolic) pathways generally involve the use of both ATP and reducing power (usually in the form of NADPH) for the production of new organic compounds. One major biosynthetic pathway, the synthesis of carbohydrates from CO2 and H2O during the dark reactions of photosynthesis, was discussed in the preceding section. Additional pathways leading to the biosynthesis of major cellular constituents (carbohydrates, lipids, proteins, and nucleic acids) are reviewed in the sections that follow.

Carbohydrates

In addition to being obtained directly from food or generated by photosynthesis, glucose can be synthesized from other organic molecules. In animal cells, glucose synthesis (gluconeogenesis) usually starts with lactate (produced by anaerobic glycolysis), amino acids (derived from the breakdown of proteins), or glycerol (produced by the breakdown of lipids). Plants (but not animals) are also able to synthesize glucose from fatty acids—a process that is particularly important during the germination of seeds, when energy stored as fats must be converted to carbohydrates to support growth of the plant. In both animal and plant cells, simple sugars are polymerized and stored as polysaccharides.

Gluconeogenesis involves the conversion of pyruvate to glucose—essentially the reverse of glycolysis. However, as discussed earlier, the glycolytic conversion of glucose to pyruvate is an energy-yielding pathway, generating two molecules each of ATP and NADH. Although some reactions of glycolysis are readily reversible, others will proceed only in the direction of glucose breakdown, because they are associated with a large decrease in free energy. These energetically favorable reactions of glycolysis are bypassed during gluconeogenesis by other reactions (catalyzed by different enzymes) that are coupled to the expenditure of ATP and NADH in order to drive them in the direction of glucose synthesis. Overall, the generation of glucose from two molecules of pyruvate requires four molecules of ATP, two of GTP, and two of NADH. This process is considerably more costly than the simple reversal of glycolysis (which would require two molecules of ATP and two of NADH), illustrating the additional energy required to drive the pathway in the direction of biosynthesis.

The model is called a double helix because two long strands twist around each other like a twisted ladder. The rails of the ladder are made of alternating sugar and phosphate molecules. The steps of the ladder are made of two bases joined together with either two or three weak hydrogen bonds.

Explanation:

Application of fertilizer granules to the yard is not a common source of air pollutants.

The natural and artificial airborne components, which are released into the air resulting in air pollution are known as air pollutants. These are detrimental to health of human beings as well as the entire planet.

Agriculture is an essential sector, which contributes to air quality and environmental effects. The air pollutants from agriculture like hydrogen sulfide, ammonia, toxic organic components, particulate matter, and pesticides are contributing to human health issues.

Burning yard waste release harmful gases like carbon monoxide to the atmosphere contributing to health issues. While driving car, combustion of fuels takes place, which release air pollutants to the atmosphere.

The application of fertilizer granules to the yard is the common source of water pollutant as washing off of fertilizers into the water bodies results in water pollution, which is harmful to the aquatic species and affects the food chain associated with it.

Thus, the correct answer is option D.

Answer:

1. It serves as the functional unit of the nervous system. b. neurons

2. It collects information from the sense organ such as the eyes and the nose. c. peripheral nervous  system

3. It serves as the primary organ of the  central nervous system. f. spinal cord​  

4. It controls or regulates the body's internal brain environment, including the body temperature,  pulse and respiration rate, and bood pressure. e. autonomic nervous  system

5. It is one of the systems that is directly involved in maintaining the normal functions of cells. d. nervous system  

Explanation:

Neuron: Neurons are the structural and functional units in the nervous system.  Neurons transmit nervous impulses. These cells are formed in general by a cellular body, dendrites that are cytoplasmic extensions that receive stimuli from other cells, and an axon that is a long formation capable of conducting the electrochemical signals. Every neuron forms connections with other neurons. These connections are known as synapsis.

Peripheral nervous  system: Sense information is received by the peripheral nervous system and processed by neurons and synapses in the central nervous system. There are three types of neurons involved in this transmission: sensory or efferent neurons, interneurons, and motor or efferent neurons.

Spinal cord: The nervous system might be divided into the central nervous system and peripheral nervous system. There are two organs involved in the central nervous system that funtion as control centers. One of them is the brain, and the other organ is the spinal cord, surrounded by the vertebral column.  

Autonomic nervous  system: The autonomic nervous system is conformed by the sympathetic nervous system and the parasympathetic nervous system. It has too many functions in the organisms, controlling pressure, heart bitting, body temperature, sexual responses, urination, digestion, general metabolism, among others. It controls and regulates the whole organism.  

The nervous system: Homeostasis refers to stability, balance, or equilibrium. The organism needs to maintain homeostasis to guarantee the correct functioning of cells, tissues, organs, and so on. The homeostatic regulation is controlled by the endocrine system and by the nervous system, which acts as the control center.

Answer:There is a fundamental difference in the way energy and matter flows through an ecosystem.Matter flows through the ecosystem in the form of the non-living nutrients essential to living organisms. When a living organism dies, nutrients are released back into the soil. These nutrients then are absorbed by plants, which are eaten by the herbivores. Matter, once again, is passed on. The herbivore is eaten by a carnivore (and matter is yet again transferred therein). Ultimately, when the carnivore dies, matter is returned back to the soil by the decomposers and the cycle repeats. So you see, matter is recycled in the ecosystem.Unlike matter, energy is not recycled through the system. A part of the energy is lost at each stage.

Explanation:

As every single living organism, the mice also have their own unique requirements as to how much food they need to produce enough energy in order to stay healthy. Because the mice are small, warm-blooded, highly active, and have very fast metabolisms, they need a lot of food for their size.

If one mouse needs four square meters of grass to stay healthy, so if we want to find out how much grass is needed for more mice we just need to multiply the number of mice by the amount of grass needed for one mice. In this case, we have 50 mice:

4 x 50 = 200

We got 200 square meters of grass, meaning that that would be the amount/area of grass that will be enough to support the population of 50 mice.

Answer:

III-5 is male.

Individual III-5 is affected by the genetic condition.

Individual III-5 is the proband.

Explanation:

In human pedigrees, males are represented by squares while females are represented by circles. Individuals affected by the focus trait in human pedigrees are usually shaded, those that are carriers are half-shaded, while those that are not affected at all are not shaded in any form.

Thus, from the pedigree (see the attached image), III-5 individual is a male and affected by the genetic condition in focus.

Also, III-5 individual is a proband, because a proband is an individual that is first affected by a genetic trait in a family.
