Answer:

Spoilage microbes produce acid

Explanation:

When food becomes spoiled or is unprotected, bacteria will invade the food. These types of bacteria are called spoilage bacteria. The bacteria will multiply by consuming the nutrients from the food and grows very rapidly. In certain conditions, the invading bacteria will produce acids that protects them and creates a barrier for other microbes. This acid is what gives spoiled food a sour taste.

<em><u>Crude oil, coal, wind and natural gas are all primary energy sources. Electricity is not a primary energy source, it's an energy currency (see electricity as an energy currency for an in depth discussion). Likewise, secondary fuels are also energy currencies and aren't primary energy sources, they must be made.</u></em>

Answer:

In case of a physical support there is a bone system involved, in case of the maintenance of the  body weight there is  wide spectrum of thyroid hormones as well as leptin and ghrelin, according to the recent studies.

Explanation:

There is a whole spectrum of physiological  body systems involved in the maintenance of the body weight in humans, as well as metabolism.  One of the most important hormones are thyroid hormones. According to the most recent studies, the major role there is an adequate function of the digestive system as well. The most important digestive-related hormones are leptin and ghrelin.

In case of the physical protection of the human body weight the major role have bones, cartilages and ligaments. All of the aforementioned structures support the human body organs and other structures. In case of skeleton, it has been estimated that it consists of 206 bones. In case of younger individuals, the human skeleton has a greater protective effect to other body systems. In case of bones, its main role is to have a rigid support for internal organs and other body structures. In that way, the body weight is is supported against the force of gravity. Additonaly, it provides a support for muscles to maintene their movements as ligaments bind to the distal and proximal parts of the corresponding bones. If we analyze the upper parts of skeleton, their promienent role is in the lifting and carrieng objects etc. The lower parts of the skeleton are involved in a variety of functions such as walking, runinng, playing sports etc.

In case of internal portions of skeleton, it is necessary to outline the major role of skeleton for example in the abdominal and peritoneal cavities. In these cases, the role of skeleton is to act protectively to the contained organs in those cavities. In case of bones themselves, they act as aa storage site for diverse minerals (calcium, phosphate etc. ). The bone marrow is a storage site for the production of blood components producing cells.

Thyroid hormones have an essential role in the body weight regulation. Their major role is through the regulation of the energy in the human body. Thyroid impairment (such as hyperthyroidism, hypothyroidism) may have a large impact on the changes in the body weight and basal metabolic rate.

The most important thyroid hormones studied in the context of the body weight regulation are free triiodothyronine (T3), free thyroxine (T4), total T3, total T4 and thyroid stimulating hormone (TSH). Thyroid hormones regulate the basal metabolic rate via increasing ATP production and regulation of the Na⁺/K⁺ and Ca₂⁺ concentrations and gradients.

Leptin and ghrelin are hormones that regulate energy balance. Leptin mediates a long-term regulation of energy balance. Leptin suppresses food intake and regulates  energy expenditure.. In that way, leptin leads to weight loss. Leptin is a 6-kDa protein with helical structure, secreted from white adipocytes. The leptin receptors have a role similar to the cytokine receptor I class via transduction mechanisms. Leptin receptors form homodimers. It has been documented that in case of food deprivation, there is a rapid decrease in leptin gene expression. Leptin acts centrally. It inhibits the synthesis and  effect of neuropeptide Y. Such role is the most prominent in the arcuate nucleus of the hypothalamus. There is a lipostatic theory of leptin. Leptin is secreted in the white adipocytes, afterwards secreted into the blood circulation and transported to brain structures. In the brain it inhibits or release the aforementioned factors in order to regulate food intake.

Ghrelin is a fast-acting hormone. It has the role in the meal initiation. It is known that leptin resistant individuals are obese. Ghrelin is a 28-amino acid that stimulates appetite and the release  of growth hormone. Nearly 70 percent of ghrelin is secreted by the stomach and small intestine. Ghrelin has a major role in white adipose tissue where it stimulates adipogenesis, fat storage enzymes and increases trygliceride concentration. It decreases lipolysis.

In the energy pyramid below, what would most likely happen to all other levels if a disease killed off all of the rabbits? *
Pavlova-9 [17]
The answer is A. Rabbits eat grass. The snakes eat the rabbits and the hawks eat the snakes. So if rabbits died off, so would the snakes, and the hawks. Because both of their food sources would deplete. And grass would flourish.

Wittaler [7]

In the military strategy of the south the army remains effective, and mobile before an enemy that is stronger to wear it off over time. The plan of the military strategy of the north has three steps: the Union called for the blockade of the south coast, the capture of Richmond, the capture of Mississippi R. With this plan they toppled the south.
