Are humans a dead end host for streptococcus pneumonia? If yes please explain why. Thank you!
Answer:
No, because Pneumonia can be transferred from one person to another.
Explanation:
Because humans are the only natural host for S. pneumoniae, our data suggest that the CbpA-mediated recruitment of complement FH may contribute to host tropism of this pathogen. A person can spread the germs that cause pneumonia when he or she coughs and expels the bacterial or viral infections that caused the disease. The droplets containing the virus or bacteria can land on a common surface, such as a table, telephone, or computer. Anyone can get pneumococcal disease, it occurs more frequently in infants, young children, the elderly or in people with serious medical conditions such as chronic lung, heart or kidney disease. Others at risk include alcoholics, diabetics, people with weakened immune systems and those without a spleen.

How does the cardiovascular system/ respiratory system/ nervous system/ digestive system work together?
Your respiratory system takes in oxygen from the air. It also gets rid of carbon dioxide. Your digestive system absorbs water and nutrients from the food you eat. Your circulatory system carries oxygen, water, and nutrients to cells throughout your body.
(1) Inhales (breathes in) Oxygen - good for the body - gives it to the Circulatory System to be transported throughout the body through the blood.
(1) Digestive System gets nutrients (good) from food and hands it over to the blood and Circulatory System then carries those nutrients where they need to go.

The human body contains trillions of cells, 78 different organs and more than 60,000 miles of blood vessels if you stretched them end-to-end. Incredibly, all of these cells, vessels and organs work together to keep you alive.
Each organ belongs to one of ten human body systems. These body systems are interconnected and dependent upon one another to function. Your heart does not beat unless your brain and nervous system tell it to do so. Your skeletal system relies on the nutrients it gains from your digestive system to build strong, healthy bones.
There are 10 body systems:
Circulatory
Respiratory
Nervous
Muscular
Skeletal
Digestive
Endocrine (hormones)
Lymphatic, or immune system
Reproductive
Integumentary (skin, hair)

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.

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
(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.

Explanation:
2. Explain the difference between cohesion and adhesion as they apply to water, as well as the results that they produce.
Answer:
Water is drawn to water due of its cohesion.
Water is drawn to other substances due to its adhesion.
Explanation:
Surface tension on water is created by cohesion, which binds hydrogen bonds together. Adhesive forces drive water toward other molecules because water is attracted to them.
Adhesion is what distinguishes a water drop from a droplet. Water has a high degree of cohesion—it has the highest cohesion of all the nonmetallic liquids. While water's cohesive properties cause it to stick together and form drops, chemistry and electricity are also involved at a more detailed level in order for this to be possible.
Cohesion and adhesion are properties of water that involve its molecular interactions. Hydrogen bonding between water molecules causes cohesion, which causes surface tension and vigorous liquid column movement in plants. As opposed to capillary action, which allows water to ascend confined tubes defying gravity, adhesion is the attraction between water molecules and other things.
Cohesion in water arises from the hydrogen bonds formed between its molecules. These bonds create a strong attraction, causing water molecules to stick together. This phenomenon results in high surface tension, allowing some insects to walk on water and water droplets to form beads. Cohesion also contributes to the movement of water through plants, as it enables water to be pulled up the plant's vascular system against gravity in a process called transpiration.
Adhesion, in the context of water, refers to the attraction between water molecules and other substances, such as the walls of a narrow tube. This property allows water to climb up thin tubes, even defying gravity, through capillary action. This process is seen in plants, where water is drawn up from the roots to the leaves, providing essential nutrients. Both cohesion and adhesion play vital roles in water's movement and distribution in the natural world.

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?
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).

I need someone to fully describe interphase, prophase, metaphase, anaphase, telophase, and cytokenisis
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.

Answer:
[tex] \: [/tex]
Carbon moves from fossil fuels to the atmosphere when fuels are burned. When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas.
Answer:
The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth. Carbon is the main component of biological compounds as well as a major component of many minerals such as limestone. Along with the nitrogen cycle and the water cycle, the carbon cycle comprises a sequence of events that are key to make Earth capable of sustaining life. It describes the movement of carbon as it is recycled and reused throughout the biosphere, as well as long-term processes of carbon sequestration to and release from carbon sinks. Carbon sinks in the land and the ocean each currently take up about one-quarter of anthropogenic carbon emissions each year.
