Approximately how much methane does one cow produce per year? How does the greenhouse gas warming effect of methane compare to carbon dioxide? Describe the organisms that digest and ferment the hay inside of the cow’s stomach? How are scientists reducing the amount of methane released from cows?
Answer:
Cattle and other ruminants are significant producers of the greenhouse gas methane—contributing 37 percent of the methane emissions resulting from human activity. A single cow on average produces between 70 and 120 kg of methane per year and, worldwide, there are about 1.5 billion cattle.
While carbon dioxide is typically painted as the bad boy of greenhouse gases, methane is roughly 30 times more potent as a heat-trapping gas. ... As temperatures rise, the relative increase of methane emissions will outpace that of carbon dioxide from these sources, the researchers report.
The cow's rumen is like a large fermentation vat. More than 200 different bacteria and 20 types of protozoa help the cow to utilize fibrous feedstuffs and non-protein nitrogen sources. ... Bacteria adhere to the feed and gradually digest the fermentable material.
“You can probably reduce methane by about 20-25% by altering diet,” he says. One study by researchers at the University of California, Davis, estimated it might be possible to reduce global methane emissions from cows by 15% by changing their diet.

What would be the functional problems that would be experienced by a person in which the fiber tracts listed below have been cut. As part of your description give an example of an everyday event or activity and how it would be affected if the given tract was cut. Type your answers by number in the response box. 1. Dorsal column-medial lemniscal pathways 2. Anterolateral pathways 3. Spinocerebellar tracts 4. Pyramidal tracts
1. Dorsal column-medial lemniscal pathways - It would prevent the body from receiving stimuli related to pain and temperature: Corresponds to sensory pathways related to an organism's proprioceptive awareness. It is through these pathways that sensory stimuli and electrical impulses are transmitted from the body to the brain resulting in the display of quick and efficient responses. If cut, the individual would not be successful in receiving stimuli related to pain and temperature.
2. Anterolateral pathways - It would also prevent the sensation of pain and temperature, in addition to hindering the perception of touch and pressure: Located in the anterior part of the lateral column, this pathway is responsible for the transmission of nociceptive information, generally related to pain awareness. and temperature. Its cut would not only make it difficult to transmit these factors, but it would also make it difficult to transmit extroceptive information to the cortex.
3. Spinocerebellar pathways - would hinder information about the position of body members and joints: This pathway is located between the spinal cord and the ipsilaterally in the cerebellum. It consists of thousands of axonal fibers whose main function is to transmit information about the location of the body members, arms and legs, in addition to their joints. Its cut would make it difficult, or even prevent this information from being captured by the brain.
4. Pyramidal pathways - It would prevent the union of the cerebral cortex to the motor neurons of the spinal cord: It is formed by several axons that extend between the cerebral cortex and the spinal cord passing motor information that would be interrupted if the path was cut.
The Functional problems to be experienced when each fiber tracts is cut ;
1) Inability of to feel pain and temperature stimulus
2) Inability to perceive touch and pressure by the person
3) Inability to determine position of body organs like hands and legs
4) Prevention of the unionization of the cerebral cortex and the motor neurons
Every Fiber tract found in the human body system play a vital role in the overall functioning of the human therefore when any of the fiber tract is mutilated ( cut ) it presents some functional problems to the body.
When Dorsal column-medial lemniscal pathways is cut It would prevent the human body from receiving pain and temperature stimulus.
When Anterolateral pathways is cut the functional problem experienced is Inability to perceive touch and pressure by the person
When Spinocerebellar tracts are cut the individual will experience the Inability to determine position of body organs like hands and legs
When Pyramidal tracts are cut the functional problem experienced is the Prevention of the unionization of the cerebral cortex and the motor neurons located in the spinal cords

2. kinetic
3. kinetic
Answer:
1 - Potential 2 - Kinetic 3 - Potential and Kinetic
Explanation:
Potential energy is the energy that an object has when it has a certain amount of elevation from the ground level and to calculate it, we can multiply the mass of the object with the gravitational acceleration constant.
hKinetic energy is the energy that the object has when it has a speed above zero, when it is moving. We can calculate the kinetic energy by multiplying the mass of the object with it's speed.
In the first option, the pendulum has a height because it is just about to fall down, but it has no speed. So it only has potential energy.
In the second option, the pendulum is between the two ends so it is at the equilibrium point where it has no elevation but it has speed. So İt only has kinetic energy.
In the third option, the pendulum is still moving to the maximum height, so it has both elevation and speed, giving it both kinetic and potential energy.

Place in correct order the following steps in the process of appositional growth of cartilage. a: New matrix is produced and secreted. b: Chondrocytes differentiate, each in its own lacuna. c: Stem cells undergo mitosis. d: Committed cells differentiate into chondroblasts.
Answer:
c: stem cells mitosis stem.
d: the compromised cells differentiate into chondroblasts.
a: New matrix is produced and secreted.
b: Chondrocytes differ, each in its own gap.
Explanation:
The appositional growth of cartilage occurs in an appositional order, thus generating these cartilage structures to give future bone structures or mature cartilages themselves.
In the cartilage of growth of long bones this process happens.
Chondroblasts are differentiated cells that can form the extracellular matrix, and chondrocytes would be the mature form of these that are submerged in their MEC once they reach the secretion limit.
The constant cartilage of cellular, mineral and organic structures, with organic compounds predominating (almost 80 percent are collagen fibers, proteoglycans and glycoproteins), that is why this tissue has a certain elasticity.

The number of people newly infected increased from 1990 to 1996 and then began to decrease. The number of deaths due to AIDS increased from 1990 to 2002, and then began to level off and decrease. Since 2000, there has been an increase in the number of people living with HIV, but a decrease in the number of people newly infected with HIV. Since 1990, both the number of new HIV infections and the number of deaths due to AIDS has consistently increased. The life span of a person living with HIV has become shorter. Twice as many people were living with HIV in 2008 than in 2000.
Answer: A. Since 2000, there has been an increase in the number of people living with HIV, but a decrease in the number of people newly infected with HIV.
Explanation:
The statement "Since 2000, there has been an increase in the number of people living with HIV, but a decrease in the number of people newly infected with HIV" best supported by the data in the graph. Hence, option A is correct.
What is HIV?The virus known as HIV (human immunodeficiency virus) targets the immune system of the body. HIV can cause AIDS (acquired immunodeficiency syndrome) if it is not treated. Right now, there is no efficient treatment.
Nevertheless, since 1996, there have been fewer new infections. For this reason, we can assume that if we look at the year 2000, we will observe that there was a rise in the number of HIV-positive persons but a decline in the number of HIV-positive people.
Therefore, since 2000, there has been an increase in the number of people living with HIV, but a decrease in the number of people newly infected with HIV.

5. fewer amounts of the hormone
6. parathyroid hormone-like hormone (PTHLH)
7. the thyroid and parathyroid glands
8. Steroid hormones are produced from cholesterol, while nonsteroid hormones are produced from amino acids.
Explanation:
Hormones are signaling molecules secreted by the body to control cellular activities The endocrine glands are glands that don't have ducts to carry their secreted products (hormones) to the surface. Endocrine glands include the hypothalamus, ovaries, testes, pancreas, adrenal glands, parathyroid glands, pituitary gland, pineal gland, thymus and thyroid glands. The pituitary gland is an endocrine gland that secretes many hormones into the bloodstream, which are capable of controlling the functioning of other organs and glands. During the puberty stage, this gland secretes LH and FSH gonadotropin hormones that affect male and female gonads in order to activate the production of sex hormones. The adrenal glands secrete cortisol, which is known as the stress hormone. These glands also produce adrenaline which regulates visceral functions such as, for example, respiration. The parathyroid hormone-like hormone (PTHLH) is generated by epithelial cells and plays important roles in fetal and adult tissues, (i.e., cell proliferation, differentiation and morphogenesis). The thyroid gland regulates body temperature, while parathyroid glands control the calcium level in the blood by secreting the parathyroid hormone (PTH). Steroid hormones are lipidic hormones known to bind steroid receptors and they can easily cross the cell membrane, while non-steroid hormones cannot diffuse across the cell membranes and they are secreted by the endocrine system.
