In human populations of northern European origin, the disorder called hemochromatosis causes excess iron uptake from food and affects one in 200 adults. Among individuals 15 to 50 years old, men are ten times as likely as women to suffer from iron overload. Part A Taking into account this range of ages, what explains this difference
Answers
Answer:
Females of reproductive age lose iron through menstrual blood
Explanation:
Iron is an essential micronutrient involved in the formation of hemoglobin, myoglobin and many enzymatic groups. Moreover, hemochromatosis is a genetically inherited disorder caused by mutations in genes associated with the processes of absorption, transport and storage of iron. The excess of iron is stored in different organs (e.g., liver, heart, pancreas, etc), causing characteristic tissue damage. During each menstrual cycle, women and girls suffer a blood loss of approximately 40 ml, which is associated with an average loss of 1.6 mg of iron. In consequence, it is expected that women of reproductive age (ie, 15–49 years) lose iron during their menstrual periods, thereby avoiding iron overload caused by hemochromatosis.

Hydrophytes is flood tolerant plants, barley is salt tolerant crop and sorghum is a drought tolerant crop.
Explanation:
Hydrophytes also known as flood tolerant plants that have adaptations to survive flood problems. The plant has the development of air spaces in the roots and stems which allow diffusion of oxygen from the aerial portions of the plant into the roots. Barley shows a greater degree of salt tolerance by applying method of osmoregulation which helps the plant to tolerate salt stress. Sorghum is a plant that is adapted to drought condition. These plants have less number of stomata and waxy layers on the leaves which lowers the rate of evaporation or transpiration.

Explain (in details), starting with the motor neuron, how muscle contraction occur. List all the molecules involved in this
process.
Answers
Muscle contraction is a complex process that involves the interaction of various molecules. It starts with the motor neuron, which carries the signal from the brain or spinal cord to the muscle. The signal, known as an action potential, travels down the motor neuron and reaches the neuromuscular junction, where the motor neuron and muscle fiber meet.
At the neuromuscular junction, the action potential triggers the release of a neurotransmitter called acetylcholine (ACh) from the motor neuron. ACh then binds to receptors on the muscle fiber's membrane, causing it to depolarize. This depolarization propagates along the muscle fiber's membrane and into the deeper regions of the muscle fiber through a network of tubules called the transverse tubules (T-tubules).
The depolarization of the T-tubules activates another set of tubules called the sarcoplasmic reticulum (SR), which is a specialized structure within the muscle fiber. The SR releases calcium ions (Ca2+) into the muscle fiber's cytoplasm. The increase in Ca2+ concentration in the cytoplasm triggers a series of events that lead to muscle contraction.
The rise in Ca2+ concentration allows the Ca2+ ions to bind to a protein called troponin, which is part of the thin filaments in the muscle fibers. The binding of Ca2+ to troponin causes a conformational change in the troponin-tropomyosin complex, exposing the active sites on the actin filaments.
Next, another protein called myosin, which is part of the thick filaments, binds to the exposed active sites on actin, forming cross-bridges. This binding triggers the release of energy stored in the myosin molecule, causing the myosin heads to change their shape and pull the actin filaments towards the center of the sarcomere (the basic unit of muscle contraction).
ATP, adenosine triphosphate, is the molecule that provides the energy for this process. When ATP is hydrolyzed to ADP and inorganic phosphate (Pi), the energy released is used by the myosin heads to move and generate force.
The cycle of myosin binding to actin, pulling the actin, and then detaching and resetting is repeated as long as Ca2+ is present and ATP is available. When the action potential ceases and Ca2+ is pumped back into the SR, the troponin-tropomyosin complex blocks the active sites on actin, and the muscle relaxes.
In summary, muscle contraction involves a series of events starting with the motor neuron, where the action potential triggers the release of ACh. This leads to depolarization of the muscle fiber, activation of the SR, release of Ca2+, binding of Ca2+ to troponin, exposure of the active sites on actin, and the formation of cross-bridges between myosin and actin. The hydrolysis of ATP provides the energy for the myosin heads to generate force and pull the actin filaments, resulting in muscle contraction.

refer to the section global waste clock (tab at the top of the page). what percentage of global waste is not collected at all?
Answers
The amount of global waste produced per person per day varies greatly over the world, from 0.11 to 4.54 kilos, with an average of 0.74 kilograms. Despite having only 16 percent of the world's population, high-income nations produce around 34 percent, or 683 million tones, of the waste produced worldwide.
By 2050, worldwide garbage is anticipated to reach 3.40 billion tonnes, more than double the rate of population growth during that time. In general, trash generation and income level are positively correlated. In comparison to low- and middle-income countries, where it is anticipated to rise by roughly 40% or more, daily per capita trash creation is forecast to rise by 19% in high-income countries by 2050. At the lowest income levels, waste generation first falls and then rises. By 2050, it is anticipated that the overall amount of waste produced in low-income nations will have increased by more than three times. The Middle East and North Africa region produces the least amount of waste globally, at 6%, whereas East Asia and the Pacific account for 23% of global waste production.

what is the responding variables when green papaya is used to cook meat
Answers
Answer:
The responding variable would be the meat becomes tenderized.
Explanation:
The Green Papaya is rich in an enzyme known Papain and this is the compound which has the ability to break down meat fibres. Raw Papaya is almost tasteless and not sweet at all, which makes it a suitable choice for marinating meat successfully. Papain is an enzyme, present in the leaves, latex, root, and fruit of the papaya plant. As an enzyme, papain catalyses the breakdown of proteins by hydrolysis (addition of a water molecule). This means that papain is able to break down tough meat fibers and make meat more tender. Therefore, meat can cook faster when a papaya is added. Tasters characterized green papaya as “clean-tasting” and “like cucumber or jícama”; in fact, jícama and seeded cucumber make good substitutes if green papaya is unavailable. GREEN PAPAYA The firm white flesh of green papaya comes from the same fruit as orange papaya—it just hasn't ripened.
