Answer:

they soak up the rain on steep hillsides

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.

Answer:

a. 0.03054 b. 0.000032 c. sorry I am not perfect

Explanation:

A. 0.03054 grams = 3.054 x [tex]10^-^2[/tex] grams

B. 3.02 x [tex]10^-^5[/tex] = 0.0000302

C. 3.3 x [tex]10^-^4[/tex] mL= 300

Powers of 10 are used in scientific notation to express extremely large or extremely small quantities. The formula is "[tex]\rm a * 10^b[/tex],"

where "a" is an integer representing a value between 1 and 10 (inclusive), and "b" is an integer representing a power of 10.

To write 0.03054 grams in scientific notation, we move the decimal point three places to the right to make the number between 1 and 10. this results in:

0.03054 grams = 3.054 x [tex]10^-^2[/tex] grams

To write [tex]3.02 * 10^-^5[/tex] in conventional notation, as indicated by the exponent, we move the decimal point five places to the left. this results in:

3.02 x [tex]10^-^5[/tex] = 0.0000302

To evaluate (3.3 x [tex]10^-^4[/tex] mL) / (1.1 x [tex]10^-^6[/tex] mL), we divide the numbers in the numerator and denominator:

[tex](3.3 * 10^-^4 \rm mL) / (1.1 * 10^-^6 \rm mL) \\= (3.3 / 1.1) * (10^-^4 / 10^-^6) \\= 3 * 10^2[/tex]

Therefore, (3.3 x [tex]10^-^4[/tex] mL) is equal to 300.

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.

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.

Answer: The answer should be B "O A hereditary genetic mutation that causes a resistance to malaria."

Explanation:

I do FLVS also you can find this out in your lesson 3.04 on page 5.

It says, "Sickle-cell disease is a genetic disorder that gives red blood cells a crescent shape instead of the typical disk shape. Sickle cells are stiff and sticky. They tend to block blood flow in the blood vessels of the limbs and organs. Blocked blood flow can cause pain, serious infections, and organ damage. This genetic disease is recessive, meaning the allele must be inherited from both parents to be expressed in a person’s phenotype. It is caused by a mutation in the gene that produces hemoglobin, the blood’s principle oxygen-carrying protein. Sickle-cell disease occurs more commonly in people and descendants from tropical and subtropical regions where malaria is common. Scientists have discovered that individuals with just one allele for sickle-cell disease are not only healthy, but they actually have a high resistance for the parasite that causes malaria. This resistance gives the carriers of one sickle-cell allele a great advantage over malaria, which claims more than a million lives each year, and explains why the allele for this dangerous genetic disease survives to be passed down to future generations."

The sickle cell gene is inherited and results in sickle cell disease. You cannot catch HPV from an infected person because it is not brought on by whatever the parents did either before or during the pregnancy. Thus, option B is correct.

Red blood cells are typically disc-shaped and sufficiently flexible to pass readily through blood arteries.

Red blood cells with sickle cell disease have a crescent or “sickle” shape. Because sickle cells impede blood flow to particular organs, sickle cell disease complications can develop.

The severe side effects include stroke, acute chest syndrome, organ damage, various disabilities, and even early death. Acute chest syndrome lowers the blood's oxygen content.

Therefore, A hereditary genetic mutation that causes a resistance to malaria.
