Which element is a metal?
O A. Ne
O B. Xe
C. F
D. Mo
Answer:
D. Molybdenum
So a metal is: a class of elements characterized by physical properties that include shininess, malleability, ductility, and conductivity.
So what is molybdenum?
It has the atomic number 42 and is a silvery-gray transition metal. Although the free element is not found in nature, it has an extremely high melting point—the sixth highest of all known elements. It is mostly mined and manufactured for alloying, notably with steel.
Uses for molybdenum metal include:
An alloying agent gives quenched and tempered steels their hardenability and toughness. Additionally, it increases steels' strength at high temperatures (red-hardness). In nickel-based alloys (such Hastelloys) and stainless steels, it gives chemical solutions heat resistance and corrosion resistance. Electrodes for forehearths and glass furnaces that use electricity for heating. Uses for nuclear energy, such as in missile and aircraft parts (where high temperature resistance is vital).As a catalyst in the petroleum refining process. In electronic and electrical applications as a filament material.As a pillar of support for lightbulbs and radios.Electric connections that are arc resistant.Sheaths for thermocouplesCoatings for other metals that prevent corrosion and flames (generally arc deposited for metallising).A recent study of a model organism found that a specific HMG protein localized mainly to the ends of chromosomes.

A recent study of a model organism found that a specific HMG protein localized mainly to the ends of chromosomes. Given this result, the site of localization for this HMG protein would correspond to regions in humans that Contain heterochromatin similar to that of centromeres.
Telomeres are regions at chromosomal ends that are time and again truncated with every round of the cellular department. Centromeresjoin sister chromatids and are required for correct chromosome division for the duration of mitosis.
Notwithstanding their different chromosomal locations, each telomere and centromere are composed of heterochromatin, a tightly condensed complex of DNA wrapped around histones.
Due to its structurally restrictive form, heterochromatin is transcriptionally inactive, which means that proteins liable for regulating gene expression can't get entry into the tightly packed DNA. As an end result, hetechromatic regions are often gene-bad and incorporate repetitive DNA.

Nitrogen released from the breakdown of proteins A) is used to synthesize liver glycogen. B) travels in the bloodstream to the lungs, where it is excreted when we exhale. C) triggers acidosis. D) is used in the synthesis of urea, which is excreted by the kidneys in the urine.
Nitrogen released from the breakdown of proteins is used in the synthesis of urea, which is excreted by the kidneys in the urine.
The urea acid cycle transforms the nitrogen waste released during this process into urea, which is then excreted in the urine. Amino acids can be converted into energy during famine and go via the Krebs cycle.Muscle protein is broken down into amino acids while fasting, some of which are partially oxidized to provide energy. These amino acids are split up into alanine and glutamine, which are released into the circulation together with other amino acids.

Explain the processes of venous return in the abdomen. do not just list them! why must the veins employ these methods?
Answer:
Venous return (VR) is the flow of blood back to the heart.
Venous return to the right atrium is the most important factor determining cardiac output, provided both ventricles and the pulmonary circulation are normal.
Explanation:
Venous return refers to the flow of blood from the periphery back to the right atrium, and except for periods of a few seconds, it is equal to cardiac output.
Venous return is facilitated by a number of factors, including inspiration, increased total blood volume, increased venomotor tone, the cardiac suction effect, the presence of venous valves and the skeletal muscle pump.
Contraction of the skeletal muscles surrounding veins increases the pressure within the veins, pushing open the proximal valve and forcing blood toward the heart. For example, when calf muscles contract during exercise, blood is forced toward the heart, thus increasing venous return.

Describe one method for temporarily storing carbon in the natural cycle.
The one method for temporarily storing carbon in the natural cycle are Most carbon is stored in rocks and sediments, and the rest is stored in the ocean, atmosphere and organisms.
How can I control the carbon cycle?It destroys the carbon cycle by burning fossil fuels and clearing land. When logging, we remove the dense plant growth, or biomass, that stores carbon in trees, stems, and leaves. Logging of forests eliminates plants that absorb carbon froThe the atmosphere as they grow.
These are reservoirs or sinks for carbon to remove carbon dioxide from the air through the process of photosynthesis in order to convert carbon to produce food for plant growth.
Carbon moves from plants to animals. The carbon contained in plants travels through the food chain to the animals that eat them. Animals that eat other animals also get carbon from their food. cycle. The sea is a huge carbon sink that absorbs carbon. Carbon is temporarily stored in soil organic matter because plants can take years (or decades for large trees) to decompose.Read more about carbon :

Liam is dehydrated because he has not drank enough water and has been exercising.
how will his body's endocrine system respond? why?
Antidiuretic hormone (ADH) is released by the hypothalamus through the posterior pituitary gland. The kidneys receive a signal from ADH to extract water from urine, which effectively dilutes the blood plasma.
What is dehydration?A condition that develops when the body loses too much of the fluids it needs to function normally, including water.
How does the endocrine system respond to dehydration?A person who is dehydrated, characterized by a net loss of water, which leaves insufficient water in the tissues and blood. Eventually, blood plasma is used to remove the water that leaves the body as exhaled air, perspiration, or urine. The thirst response, a chain of physiological events, is initiated as the blood gets more concentrated. In the thirst center of the hypothalamus, osmoreceptors are sensory receptors that keep track of the blood's osmolality, or solute content. The hypothalamus sends signals that cause a person to become aware of their thirst if blood osmolality rises above a healthy level. Water consumption is the appropriate response, and it usually is.
A dehydrated person's hypothalamus also releases antidiuretic hormone (ADH) via the posterior pituitary gland. The blood plasma is diluted as a result of ADH telling the kidneys to extract water from urine. A dehydrated person's hypothalamus also tells the salivary glands in the mouth to preserve water through the sympathetic nervous system. The signals cause a decrease in the release of watery, sour substances. This alteration in secretions causes "dry mouth" and a thirst-inducing sensation.

10. Suppose a human blood cell containing a 0.9 percent solute concentration was put into a container of a 30 percent solute solution. Would the blood cell get bigger or smaller?
If the blood cell (hypotonic) is placed inside the 30% solute solution (hypertonic), then the cell will become smaller in the size (shrink) because of the osmotic pressure.
What are hypotonic and hypertonic solutions?Hypotonic solutions have lower solute concentrations compared to the hypertonic solution with a higher solute concentration. The blood cells have a hypotonic environment on their inside as it contains 0.9 % solute concentration.
The outer of the cell has a 30 % solute concentration making it hypertonic and hence the water from the cell will move out into the more concentrated solution making the cell shrink in the size.
