Explanation:
Essay 1 )
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

In healthy individuals, friction is a major factor affecting pulmonary ventilation
Answers
Answer: Infant Respiratory Distress Syndrome occurs when there is a lack of surfactant produced. This is common in premature infants.
Explanation:
Infant Respiratory Distress Syndrome (RDS) occurs in new born infants whose lungs are unable to produce the enough surfactant to keep their lungs expanded which would enable them to breathe properly after delivery.
It is most common in premature infants because surfactant is produced in the third trimester of pregnancy so premature infants might not get the chance to produce enough before the are delivered. RDS needs to be treated as soon as possible or else a baby could suffer damage to the brain and other vital organs.

Rhesus monkeys are more closely related to rabbits than they are to horses. (B) Horses and cows have identical amino acid sequences in their cytochrome c. (C) Humans are more closely related to rabbits than they are to rhesus monkeys. (D) Plants and animals have no similarities at all. (E) Mammals are more closely related to reptiles than they are to fish.
Answers
Complete question:
A scientist used the amino acid sequence of cytochrome c in different species to consider evolutionary relationships.
The data below summarizes the numbers of differences in the amino acid sequences of cytochrome C found in the selected species
Species compared Number of differences
Human-chimpanzees 0
Human-Rhesus monkeys 1
Human-Horses or Donkeys 7
Human-Cow, Pigs or sheeps 7
Human-Rabbits 7
Mammals-Birds and reptiles 10-15
Mammals-Fishes 18-20
Mammals-Plants 45-48
Interpretation of the data supports which of the following statements?
(A) Rhesus monkeys are more closely related to rabbits than they are to horses.
(B) Horses and cows have identical amino acid sequences in their cytochrome c.
(C) Humans are more closely related to rabbits than they are to rhesus monkeys.
(D) Plants and animals have no similarities at all.
(E) Mammals are more closely related to reptiles than they are to fish.
Answer:
(E) Mammals are more closely related to reptiles than they are to fish.
Explanation:
So, what you need to do here is to compare the number of differences found in each comparison. Remember that this information is only regarding cytochrome C. For instance, we can see that between humans and chimpanzees, the number of differences is 0. Their amino acid sequences do not differ at all. On the contrary, the comparison of mammals and plants threw a value of 45-48 differences, meaning that they are very different from each other, almost 50%.
So, this is how you need to interpret the values of the differences in this table. Now, let us go to the options,
(A) Rhesus monkeys are more closely related to rabbits than they are to horses. Rhesus monkey was not compared to any group other than humans, so we could not say that they are more related to one animal or the other.
(B) Horses and cows have identical amino acid sequences in their cytochrome. When comparing humans with horses and then humans with cows, the number of differences was the same -7-. But these results do not indicate which are the differences. Remember that we are comparing amino acid sequences, so probably the number of differences of each group with humans is the same, but the amino acid sequences between horses and cows are not.
(C) Humans are more closely related to rabbits than they are to rhesus monkeys. Humans and rhesus monkeys express only one difference in the amino acid sequence, while humans and rabbits exhibit seven differences. This result means that humans are more closely to rhesus monkeys related than they are to rabbits.
(D) Plants and animals have no similarities at all.
As we mentioned before, plants and mammals have a difference of almost 50% in their amino-acidic sequences. It does not mean that the other 50% is also different.
(E) Mammals are more closely related to reptiles than they are to fish.
The amino acid sequence of mammals and reptiles show 10-15 differences
The amino acid sequence of mammals and fish show 18-20 differences
So yes, mammals seem to be more related to reptiles than to fishes because the number of differences with reptiles is fewer.

You have colonies growing on a culture and are going to identify them. First, you do a Gram stain and viewing it on 1000x magnification, you see Gram positive cocci, no predominating arrangement. What test should you do to determine if it a staphylococcus or a streptococcus
Answers
Answer: The test that's should be done to determine if it's a staphylococcus or a streptococcus is a BIOCHEMICAL TEST known as CATALASE TEST.
Explanation:
In the laboratory diagnosis of microbiology samples, GRAM STAINING technique is used to identify bacteria pathogens in specimens and cultures by their gram reactions. The bacteria may be either gram positive or gram negative.
Gram positive bacteria when views with ×100 oil immersion stains dark purple with crystal violet and are not decolorize by acetone or ethanol. Examples of gram positive bacteria include:
--> Staphylococcus
--> Streptococcus
--> Clostridium
--> Corynebacterium
Since a gram positive cocci was identified without a predominating arrangement, further biochemical test known as catalase test should be carried out to determine if the cocci is staphylococcus or a streptococcus.
CATALASE TEST is used to differentiate those bacteria that produce catalase enzyme such as staphylococcus from non- catalase producing bacteria such as streptococcus. Catalase acts as a catalyst in the breakdown of hydrogen peroxide to oxygen and water. An organism is tested for catalase production by bringing it into contact with hydrogen peroxide. Bubbles of oxygen are released if the organism is a catalase producer, therefore staphylococcus but if no bubbles are observed, it's a streptococcus.

Hope this helps!
Measure the volume of a balloon filled with room temperature air; place the balloon in a freezer for an hour and measure its volume again would best investigate the effect temperature has on the volume of a gas. So, the correct option is C.
How volume effect the temperature of the gas?The ideal gas law states that the temperature of a gas is directly proportional to its volume. Specifically, the temperature of a gas will increase if its volume is decreased while its volume and pressure remain unchanged. If the volume of a gas is increased, its temperature will fall but its volume and pressure will remain unchanged.
This relationship can be explained by the fact that when a gas is compressed (that is, its volume decreases), the molecules are confined to a smaller area and move more away from each other and the walls of the container. Bars collide. Due to the increasing frequency of impacts, there is also an increase in kinetic energy, which increases the temperature.
So, the correct option is C.
