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.

b. If we were to dig up this plant, what type of root system should we expect to find? Describe what the roots of this plant should look like according to your identification in part a above addressing the presence or absence of the following parts: • Tap root • Lateral root • Fibrous root system • Trichomes
Answer:
Tap root
Explanation:
A large majority of dicotyledonous plants are capable of producing tap roots, which is part of a primary rot system that grows in the vertical direction - downwards. Sometimes it serves the function of storing food, as in the case of dandelions.
One main role that the trichomes (fine hair-like outgrowth) play is to defend the plant against certain insects.

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 nerve cells in your body must constantly remove substances from the cell against the concentration gradient. What type of process most likely takes place to remove substances from a cell against the concentration gradient? Explain.
Answer and explanation:
Active transport refers to a procedure, which withdraws substances from a cell against the concentration gradient. During the process, the molecules move from low concentration to a high concentration.
The mechanisms of active transport need the application of the energy of the cell, generally in the form of ATP. If a substance needs to move within the cell against its concentration gradient, that is, if the substance's concentration within the cell is more than its concentration in the extracellular fluid, then the cell must utilize energy to move the substance.

Which statement is best supported by the data in the graph? A graph entitled Number of people living with H I V, number of people newly infected with H I V and number of AIDS deaths worldwide from 1990 to 2008 in millions is shown. Year is on the horizontal axis and number of people is on the vertical axis. The number of people living with H I V steadily increases over the years. 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.

What is the allele frequency?
Answer:
Explanation:
Allele frequency is the how often or what's the percentage of a particular allele in a population. Allele is referred to as version of a gene that is located on the chromosome.
For example, a gene causing death in rats might have alleles, W and w. Each would be a separate allele and the frequency would be how often or what's the percentage of W or w that is present in the population.
Suppose we are trying to find frequency of W or w allele in a population then the formula is
Allele Frequency = [# of copies of certain allele (either W or w)] / [Total number of W and w alleles]
Now suppose we have 4 WW and 2 ww in a population.
First we count up W allele then we have (4 * 2)= 8 W (we multiplied by 2 because each organism has WW, 4 WW is short of of writing WW , WW, WW, WW)Same concept for 2ww, we have total w = 2 * 2 = 4wTotal alleles = W + w = 8 +4 =12
Allele Frequency for W = 8 / 12 = 66.67%
Allle Frequency for w = 4 / 12 = 33.33%

Adaptive immunity comprises two branches: humoral immunity and cellular immunity. What are the characteristics of each of the two arms of the adaptive defense system
Answer:
Adaptive or acquired immunity is that we acquire throughout our lives through vaccines (active), breast milk (passive) or injection of specific artificial or natural antibodies to a certain pathogen (passive).
The two great arms of this immunity are the humoral and the cellular.
The humoral refers to the cytokines and immunomodulatory molecules that are responsible for transmitting fundamental messages between defense cells in order to coordinate the destruction of the pathogen between them.
Instead, cellular immunity speaks about cell lineage such as b, t, tcd4 lymphocytes, natural killers, plasmacytes, etc.
It can be said that the humoral factor is the one that coordinates the pathways and the relationships between the cells of the acquired immunity, both are important because the two need each other for adaptive immunity to work.
Explanation:
Examples of the humoral factor: pro and anti inflammatory cytokines, interleukins, complement chain, antibodies, TNF alpha, beta, etc.
Examples of cellular factor: plasmacyst, b lymphocyte, t lymphocyte, NT lymphocyte
