What effect would uncontrolled population growth have on land?*
A) increased soil fertility and decreased erosion
B) increased soil fertility and increased erosion
C) decreased soil fertility and decreased erosion
D) decreased soil fertility and increased erosion
Answers
(D) is the right answer ........
Uncontrolled population growth affect the soil fertility and soil erosion i.e. it decreases soil fertility and increases soil erosion.
what is uncontrolled population growth?uncontrolled population growth is the area where the proportion of urban population has increased faster than the nation's average rate of population growth.
what is soil erosion ?soil erosion is a gradual process that occurs when the impact of water or wind detaches and removes soil particles, causing the soil to deteriorate.
what is soil fertility ?soil fertility is the ability of a soil to sustain plant growth by providing essential plant nutrients and favorable chemical, physical, and biological characteristics as a habitat for plant growth.
The population increases so that the demand for food increases, lack of arable land leads to intensive cultivation, reclamation to expand cultivation land on sloping hills increases soil erosion, causes degradation, infertile soil.
Therefore, use of chemical fertilizers and plant protection chemicals makes land resources, surface water sources of the mainland contaminated.
Reclamation makes area of forestland narrowed, depletion of natural resources, natural environment polluted.

Bacteria are decomposers which break down dead material and recycle it. They also can be producers, making food from sunlight, such as photosynthetic bacteria, or chemicals, such as chemosynthetic bacteria.The most influential bacteria for life on Earth are found in the soil, sediments and seas. Well known functions of these are to provide nutrients like nitrogen and phosphorus to plants as well as producing growth hormones. By decomposing dead organic matter, they contribute to soil structure and the cycles of nature. Decomposers play a critical role in the flow of energy through an ecosystem.

I need someone to fully describe interphase, prophase, metaphase, anaphase, telophase, and cytokenisis
Answers
Answer: Interphase is the phase of the cell cycle in which a typical cell spends most of its life. Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, replicates its DNA in preparation for mitosis, and conducts other "normal" cell functions, prophase is the first stage of cell division, before metaphase, during which the chromosomes become visible as paired chromatids and the nuclear envelope disappears. The first prophase of meiosis includes the reduction division, metaphase is a stage in the cell cycle where all the genetic material is condensing into chromosomes. During this stage, the nucleus disappears and the chromosomes appear in the cytoplasm of the cell. During this stage in human cells, the chromosomes then become visible under the microscope, anaphase is the stage of mitosis after the process of metaphase, when replicated chromosomes are split and the newly-copied chromosomes are moved to opposite poles of the cell, Telophase is the final stage in both meiosis and mitosis in a eukaryotic cell. During telophase, the effects of prophase and prometaphase are reversed, Cytokinesis is the part of the cell division process during which the cytoplasm of a single eukaryotic cell divides into two daughter cells. Cytoplasmic division begins during or after the late stages of nuclear division in mitosis and meiosis.

A body system is a group of parts that work together to serve a common purpose. Your cardiovascular system works to circulate your blood while your respiratory system introduces oxygen into your body.
Each Body System Works with the Others
Each individual body system works in conjunction with other body systems. The circulatory system is a good example of how body systems interact with each other. Your heart pumps blood through a complex network of blood vessels. When your blood circulates through your digestive system, for example, it picks up nutrients your body absorbed from your last meal. Your blood also carries oxygen inhaled by the lungs. Your circulatory system delivers oxygen and nutrients to the other cells of your body then picks up any waste products created by these cells, including carbon dioxide, and delivers these waste products to the kidneys and lungs for disposal. Meanwhile, the circulatory system carries hormones from the endocrine system, and the immune system’s white blood cells that fight off infection.
Each of your body systems relies on the others to work well. Your respiratory system relies on your circulatory system to deliver the oxygen it gathers, while the muscles of your heart cannot function without the oxygen they receive from your lungs. The bones of your skull and spine protect your brain and spinal cord, but your brain regulates the position of your bones by controlling your muscles. The circulatory system provides your brain with a constant supply of oxygen-rich blood while your brain regulates your heart rate and blood pressure.
Even seemingly unrelated body systems are connected. Your skeletal system relies on your urinary system to remove waste produced by bone cells; in return, the bones of your skeleton create structure that protects your bladder and other urinary system organs. Your circulatory system delivers oxygen-rich blood to your bones. Meanwhile, your bones are busy making new blood cells.
Working together, these systems maintain internal stability and balance, otherwise known as homeostasis. Disease in one body system can disrupt homeostasis and cause trouble in other body systems. If you become ill with the AIDS virus that affects your immune system, for example, you may develop pneumonia in your respiratory system, a yeast infection in your reproductive system, Candida that affects your esophagus in your digestive system or the skin cancer known as Kaposi’s sarcoma.

If a DNA molecule had a total of 1000 nucleotides and 200 of these are adenines, what would be the total number of pyrimidines in this molecule?
Answers
If a DNA molecule had a total of 1000 nucleotides and 200 of these are adenines, then the total number of pyrimidines is 500. Adenines (A) are purine bases.
DNA is a double helix molecule composed of two long chains of nucleotides that are held together by hydrogen bonds.
In DNA, there are four types of nucleotides, each containing one different nitrogenous base: Adenine (A), Guanine (G), Cytosine (C) and Thymine (T).
Adenine (A) and guanine (G) are purines, whereas cytosine (C), thymine (T), are pyrimidines.
According to the base pair rules, Adenine always pairs with Thymine, whereas Guanine pairs with Cytosine.
In this case, the number of A + T is equal to 400 (200 + 200) and the number of G + C is 600 (300 + 300), thereby the number of pyrimidines or C + T is equal to 500 (200 + 300).

If you were to hike up Mount Kilimanjaro in Tanzania, you would pass through several habitats, including savanna at the base, forest on the slopes, and alpine tundra near the top. Explain how such diverse habitats can be found at one location near the equator.
Answers
Given our knowledge of ecosystems, we can confirm that the diverse habitats found at one location near the equator are due to the changes in elevation.
The effects that elevation has on the climate are what enable the diversity of habitats on a single mountain. As elevation increases, atmospheric pressure decreases. This decrease in pressure then causes a decrease in temperature.
The base of the mountain is a dry and hot habitat, while as we travel upwards towards higher elevation we see a transition in habitats into a more tropical forest style and then eventually an alpine tundra, further proving the claim that elevation lowers the temperature.
