When a honey bee stings or a pathogen attacks, the body elicits an inflammatory response. Label the processes that happen during an
inflammatory response.
The inflammatory response is a type of body response produced in response to damaged tissue, attack of pathogen and or any other cause.
The body shows an inflammatory response in the following manner:
1. Recognition of stimulus- receptors recognize the antigens.
2. Release of inflammatory markers: affected cells produce chemicals like histamine, bradykinin, and prostaglandins.
3. Vascular permeability changes and leukocyte (WBC) recruitment- released chemicals causes the blood vessels to leak fluid causing swelling and attract WBC.
4. Accumulation of leukocytes- WBC performs the process of phagocytosis which eats dead or damaged cells and germs.

Why did Mendel need to grow two offspring generations (F1 and F2) to develop his law of segregation?
Answer:
Mendel formulated the law of segregation as a result of performing monohybrid cross experiments on plants. The specific traits that he studied exhibited complete dominance. Not all types of genetic inheritance, however, show total dominance. In incomplete dominance, neither allele is completely dominant over the other.
Explanation:
Hope this helps.
Mendel need to grow two offspring generations (F1 and F2) to develop his law of segregation because the first generation offspring had just one form of each trait. The second generation showed both forms of the trait due to segregation.
What is Law of Segregation?When an organism produces gametes, each gamete receives only one gene copy, which is chosen at random. This is defined as the law of segregation. A Punnett square can be used to predict the genotype (allele combination) and phenotype (observable traits) of the offspring from a genetic cross.
This law of segregation, called the second law of inheritance, states that during meiosis cell division (gamete formation), pairs of alleles separate from each other so that only one allele is present in each gamete.
Mendel formulated the law of segregation as a result of experimenting on monohybrid crosses on plants. The specific traits he studied showed complete dominance. However, not all types of genetic inheritance show total dominance. In incomplete dominance, neither allele is completely dominant over the other.
Thus, Mendel need to grow two offspring generations (F1 and F2) to develop his law of segregation because the first generation offspring had just one form of each trait. The second generation showed both forms of the trait due to segregation.

In many people's opinions mans impact on the environment is a big issue in our life which is easily neglected, as humans are responsible for a staggering amount of damage on the earth. Nature manages its own components.
Since the outbreak of technology and industrialisation humans have greatly had a negative impact on the environment, such as; air pollution, habitat destruction, water pollution, the burning of rainforests and land pollution. In this essay I intend to give facts and discuss the effects and causes on these topics and discuss the solutions being carried out to improve the conditions.
Air pollution effects people in areas of emission sources, such as, power plants, local industry and major roads. Humans contribute to pollution by the use of machinery in industry causing pollution to the environment. More effects of air pollution on the environment involve using diesel fuel for vehicles and coal for power along with the lack of emission controls for vehicles and industry.
Another cause of air pollution is the greenhouse gas CO2, this gas warms the earth through living things as they emit CO2 when breathing which contributes to humans also, as we add to this statistic through breathing also. CO2 is usually thought to be involved with cars, aeroplanes and power plants, in the past 150 years , CO2 has been polluting our atmosphere through the sources mentioned, this is the highest CO2 emissions recorded for a long time. More causes of air pollution is methane gas which comes from swamps which are contributed to man through flooding. Cfc's are another major cause of air pollution by man through the use of fridges and deodorants (aerosols) which harms the earth's ozone layer.
Essay 2 )
In order to meet the basic needs of increases population, the present society has under taken a series of steps like rapid industrialization, unplanned urbanisation, deforestation, overexploitation of natural sources, etc.The outcomes of the above human activities have contributed significantly to the degradation of environment around us.
Some important impacts of human activities on environment are outlined below:
1. Deforestation:
In order to provide timber and farm land to increased population, large number of forest trees are cut and forest area is converting to farm lands. The rate of deforestation is so faster that around 1.5 million hectare of forest cover is lost every year is India alone. The process of deforestation results in decreasing rainfall, increasing global temperature, loss of top soil, modification of climatic conditions etc.
2. Industrialization:
Although the industrial activities of man provide basic need of the society, simultaneously the same release a lot of pollutants to the environment. The pollutants in environment cause loss of raw materials, health hazards, increase in death rate, damage to crop, making environment unfit for living organisms etc.
3. Loss of ecological balance:
The excessive use, misuse and mis-management of biosphere resources results in disturbance in ecosystem or ecological imbalance.
4. Air pollution:
The anthropogenic release of various air pollutants to the environment causes a number of dreaded phenomena like green house effect, ozone layer depletion, acid rain and smog formation etc.
5. Water pollution:
Human activities in respect of disposal of sewage wastes, solid wastes, municipal wastes, agricultural and industrial wastes cause the environment unfit for day to day use. Besides, polluted water spreads or leads to different diseases.
6. Increased consumption of natural resources:
Since the starting of industrial era, the natural resources are constantly utilised for the production of one or more products for the day to day use of society.
7. Production of waste:
Rapid industrialization and unplanned urbanization release a lot of toxic waste material either in solid or liquid or gaseous state which induces a number of serious environmental hazards.
8. Extinction of Wildlife:
Since forests are natural habitats of wild life (both plants and animals) deforestation leads to the extinction of valuable wild life and loss of biodiversity.
9. Habitual destruction:
The commercial and industrial activities associated with mining, construction of dams, fishing, agriculture etc. cause habitat destruction which is a pathway to pollution.
10. Noise pollution:
The man-made noise due to mechanized automobile, industries, trains, aero planes, social functions etc. causes noise pollution which has impact on both biotic and a biotic components of environment.
These are the human impacts on environment

Ionic compounds form because charges attract
The formation of ionic compounds is due to when opposite charges attract and like charges repel, the attraction of opposite charges makes ionic bonds in the compounds.
What are ionic bonds?It is the kind of bonding in which electrostatic attraction happens, through which ionic compounds are formed.
Ionic bonds set the chemical connection in which one atom loses valence electrons and which are gained by another atom, the atoms involved in this connection form the more stable noble gas electrical state.
This bonding is different from covalent bonding, in covalent bonding there is sharing of the pairs of electrons making it more strong than ionic.
Therefore, ionic compounds form because opposite charges attract each other, leading to ionic bonding.

ICM.06] Scientific research shows that our global climate is changing as a result of an increase in greenhouse gases. Arctic sea ice is decreasing in both surface area and thickness. Which of the following statements best describes the
consequence of decreasing Arctic sea ice?
The melting of sea ice will decrease the effects of global warming in the area as the ice absorbs heat
O seawater levels wil decrease making t difficult for marine animals to survive.
Animals that rely on the sea le for survival may become extinct as their habitat disappears.
The milder temperatures will allow for greater survival rates for native species
As a result of decreasing Arctic sea ice, animals that rely on the sea level for survival may become extinct as their habitat disappears.
The increase in the atmospheric greenhouse gases means that more radiant energy from the sun that could have escaped back into space is being absorbed, leading to an increase in the global temperature.
The increase in the global temperature means that more Arctic sea ice would be melting and decreasing in size. As the ice melts, the water moves into seas thereby causing a rise in their levels.
A rise in sea level means the disappearance of coastal habitats. Thus, a loss in biodiversity will occur as the habitats of plants and animals disappear as a result of the rise in sea levels.

What tells a muscle when to contract?
Answer:
What tells a muscle when to contract?
Explanation:
(1) A message travels from the nervous system to the muscular system, triggering chemical reactions.
(2) The chemical reactions lead to the muscle fibers reorganizing themselves in a way that shortens the muscle--that’s the contraction.
(3) When the nervous system signal is no longer present, the chemical process reverses, and the muscle fibers rearrange again and the muscle relaxes.
Answer:
The nervous system generates a signal, which triggers a muscle to contract

Do protein channels have specificity? (i.e. Are they specific about what they let cross the membrane or can any molecule go through any channel?)
Explain how the sodium/potassium pump works. Why does this process require ATP?
Answer:
1)ATP. The concentration of glucose inside of a cell is higher than the concentration outside of that cell, yet glucose continues to enter the cell. ... Two solutions are separated by a selectively permeable membrane that is not permeable to glucose.
2)For transport efficiency, channels have an advantage over carriers in that up to 100 million ions can pass through one open channel each second—a rate 105 times greater than the fastest rate of transport mediated by any known carrier protein.
3)The sodium-potassium pump uses active transport to move molecules from a high concentration to a low concentration. The sodium-potassium pump moves sodium ions out of and potassium ions into the cell. This pump is powered by ATP. For each ATP that is broken down, 3 sodium ions move out and 2 potassium ions move in.

How dose the force of the car change as the mas of the car increases
Answer:
Increases.
Explanation:
According to Newton's Second Law of Motion:
F = ma
So, if we keep the acceleration constant:
F ∝ m
F is directly proportional to m, which means if we increase the mass, the force will also increase and vice versa.
Hence, If the mass of the car increases, Force acting on it also increases.
