Explanation:
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.
11. Radiation pollution:
The radiations from radioactive substances used in nuclear reactors and nuclear weapons can have significant impact on genetic materials of body (DMA, RHA etc.)
12. Soil erosion:
The anthropogenic processes like deforestation and overgrazing induce soil erosion which causes soil moisture reduction, lowering of productivity, decline in soil fertility etc.

Which of the following statements is NOT TRUE about photosynthesis and cellular respiration? (B.9B)
Question 19 options:
Both processes require energy
Both processes occur in the mitochondria
The chemical equations for the processes are opposite of each other.
Photosynthesis occurs in plants; cellular respiration occurs in plants and animals.
Answers
Answer:
Both processes require energy cuz respiration produces energy
Explanation:
The statement that is not true is that both processes occur in mitochondria as photosynthesis happens in chloroplasts. So the correct option is B.
What is cellular respiration in plants?While oxygen is needed for plant respiration, carbon dioxide is also released during the process. Plants, unlike people and other animals, don't have any specific structures for the exchange of gases, but they do have stomata (found in leaves) and lenticels (found in stems) that play a part in it. Compared to people and animals, leaves, stems, and plant roots respire slowly.
Respiration is distinct from breathing. Breathing is a phase in respiration that is completed by both humans and animals. Plants breathe differently through a process called cellular respiration, which they engage in throughout their whole existence since the plant cell needs the energy to survive.
Plants produce glucose molecules during this process of cellular respiration by using photosynthesis to absorb solar energy and transform it into glucose. Several real-world experiments show that plants can breathe. To provide their cells the energy they need to function and stay alive, all plants breathe.
Therefore the correct option is B.

During photosynthesis, plants and other photosynthetic organisms release oxygen into the atmosphere. Without this process, Earth's atmosphere would have little oxygen. Identify two reasons why photosynthesis is critical for animals to produce energy for life functions. How would this effect the animals ability to create the four main types of biomolecules.
Answers
Answer:
Without oxygen from photosynthesis animals would not have oxygen for the four type of biomolecules which all require oxygen. Carbon hydrogen and oxygen is carbohydrates and same for lipids. Proteins would not have the oxygen for CHON which is carbon hydrogen oxygen and nitrogen. And nucleic acids which are CHONP carbon hydrogen oxygen nitrogen and phosphorus would not have oxygen. And without oxygen the animals would die and not be able to produce these biomolecules.
Answer: To grow and reproduce, all creatures require energy. Cellular respiration is utilized by many organisms (including all plants) to create ATP, which is needed for cellular energy. As a substrate, carbohydrates such as glucose are used in the respiration reaction. Plants produce their own fuel for respiration through photosynthesis, but humans consume food to do so. Plants would not be able to breathe if photosynthesis did not occur. Furthermore, carbohydrates created during photosynthesis are needed to construct plant cell components such as the cellulose cell wall.

Answer:
A. It loses an electron
Explanation:
An atom becomes a positive ion when it loses an electron (then there are more protons than electrons in the atom) when it is trying to reach stability. This is called a Cation. The opposite of this is an Anion, when an atom gains an electron to reach stability and becomes a negative ion (because the number of electrons are higher than the number of protons).

que Graphing and Analyzing Data (Cricket Chirps) In order to determine if cricket chirps are influenced by temperature, scientists recorded the chirps at different temperatures over a month-long period. Day Temperature (Fahrenheit) Average Number Chirps (per 15 sec) 5/05 54 15 5/09 60 21 5/11 58 19 5/20 68 29 5/22 64 25 5/27 72 33 6/01 80 44. 6/06 70 31
Answers
Answer:
D16.5 degree F. Explanation : when x = 9: y = 25.2 + 3.3(9) = 54.9 deg. when x = 5 more chirps or 14: y = 25.2 + 3.3(14) = 71.4 deg. 71.4 - 54.9 = 16.5 deg.
Explanation:
ok
The first cricket: the sky's the limit. 9 chirps in a quarter of a minute, or 15 seconds, are equivalent to 36 chirps in 60 seconds. In the same amount of time, the first cricket makes 12 chirps.
When x = 9: y = 25.2 + 3.3(9) = 54.9 deg. When x = 5 more chirps or 14: y = 25.2 + 3.3(14) = 71.4 deg. 71.4 – 54.9 = 16.5 deg.
What is the temperature affect the chirping of cricket?As the temperature rises, it gets simpler to reach a particular activation energy, which speeds up chemical processes like the one that causes a cricket to chirp.
On the other hand, as the temperature drops, the reaction speeds slow and the chirping also decreases.
Although the amount of light has no bearing on their chirp, temperature does: warmer air causes a faster chirp.
The number of cricket chirps over a 15-second period multiplied by 37 will often give you the temperature in degrees Fahrenheit.
Therefore, The cricket is chirping because of the vibrations produced while the scraper is moved along the file.

What is the difference between the way energy puts limits on life and the way phosphorus does so?
Answers
Adenosine triphosphate (ATP) production, the creation of sugar and alcoholic esters, and other energy-transfer processes all need phosphorus.
What is the role of phosphorus in energy?
In many enzymatic processes, where inorganic phosphorus regulates the rate of reaction, phosphorus also serves a regulatory purpose in addition to these other tasks.
This holds true for everything from exploration to the development of young children and is determined not by our muscles and lungs but rather by the amount of energy we can obtain from food.
It has a significant impact on how the body utilizes fats and carbs. The production of protein by the body is also necessary for the development, upkeep, and healing of cells and tissues.

During pregnancy after fertilization, the embryo gets implanted in the uterine wall. So the correct option is D.
What is an embryo?The embryo is the stage of an animal's early development when it is within an egg or a mother's uterus. When referring to an unborn person, the phrase is used up to the end of the seventh week after conception; starting with the eighth week, the term "fetus" is used.
When an ovum and a sperm unite to form a sexually reproducing organism, the outcome is a zygote, or fertilized egg, which goes through a series of divisions known as cleavages as it travels down the fallopian tube. A hollow ball known as a blastula is created by the cells following many cleavages.
In most animals, the blastula adheres to the uterine lining, causing the placenta to develop and begin supplying the developing fetus with nourishment from the mother. The yolk feeds the embryo in lower animals.
The embryo differentiates into three types of tissue through the process of gastrulation: the ectoderm, which produces the skin and nervous system; the mesoderm, from which connective tissues, the circulatory system, muscles, and bones develop; and the endoderm, which produces the digestive system, lungs, and urinary system.
Therefore the correct option is D.
