Answer:

It is used for detecting bacteria

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.

Answer:

The endocrine system is a major system in the body composed of glands that secrete hormones, which are substances produced by the body to stimulate an organ or group of cells. The endocrine system controls essential bodily functions, which include movement, sexual development, sensory perception, and even growth.

Explanation:

Hormones are chemicals that are produced by the glands in the endocrine system and coordinate distinct bodily functions by carrying important messages throughout the body. They send signals to receiver cells in organs, muscles, and tissues.

Role of Hormones

Hormones have very essential roles in the body, as they regulate metabolism, growth, and sex development. For example, testosterone and estrogen are sex hormones that are released in the body to initiate sex development during puberty. The rate at which these hormones are produced and released must also be highly controlled for optimal development and growth. Hormones also control levels of hunger or exhaustion. Overall, they are very important in telling the body what to do and how to do it.

Function of Hormones

As previously mentioned, hormones serve several important functions throughout the body. They are responsible for the function of organs, in addition to controlling how the body stores and uses energy. Hormones only target specific organs or cells: for example, thyroid-stimulating hormones are released by the pituitary gland, and only target the thyroid gland. Some hormones can affect several kinds of tissues at once; for instance, the thyroid hormone, produced by the thyroid gland, can affect several bodily functions, such as heart rate and metabolism.

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.

Plants make sugar from the sun, water, and carbon dioxide in the air. a chemicls reaction happens causing photosynthesis

The flow of carbon between inorganic and organic sources in the environment is best description of the carbon cycle as a whole. Thus, option B is correct.

It is the process in which carbon compounds are interchanged among the biosphere.

For example the elemental form of carbon such as diamond and graphite in a combined state are mostly found as carbonates and as carbon dioxide gas.

It act as a blanket over our earth, by balancing the energy and also absorb  sun's long wave length radiation.

It also involve in plant photosynthesis, bioaccumulation of carbon occur in animal body by consuming plant material, after the death of the animal it can decomposed and carbon is released back into the atmosphere.

The carbon which is not released back will form  fossil fuels.

Cleavage, cleavage, fracture

The first item exhibit a cleavage. The second item exhibit a cleavage. The third item exhibit a fracture.

In mineral science, Cleavage is the process by which a mineral breaks or splits through smooth planes with a pattern because the material is stratified in a layered pattern. It generally seems regular since it fractures along its plane of weakness.

A fracture happens when a mineral splits with fractures and does not produce a particular definite shape. It frequently emerges in an erratic and irregular pattern.

From the three picture given, the first and the second item exhibit cleavage, and the third item exhibit fracture.

Alpha gamma coactivation is critical for maintaining the appropriate tension on the spindle organ during contraction of extrafusal fiber.

Alpha‐gamma coactivation is a process that the muscle use to keep or maintains it's length. It works in a way that when the muscle contracts or relaxes , the sensory neuron send the information to the central nervous system about what happen to the muscle. This lead the intrafusal and extrafusal fibers to contract.

Explanation:

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.
