Answer:
Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of chemical substances or energy, such as noise, heat, or light. (I'm sorry this is about Pollution, it should be about Pollination, I misread it sorry,)
Pollination:
Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma. The goal of every living organism, including plants, is to create offspring for the next generation. One of the ways that plants can produce offspring is by making seeds.
How do fossils provide a record of the history of life on earth
Answer: Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today.
Explanation:
Answer:
fossils are the preserved remains or traces of animals, plants, and other organisms from the past. they're showing life on earth was once different from how it is now.

Reasoning: [Fill in the Blanks with your answer]
Answer:
Claim: Various factors can tree frogs to change color, such as outdoor temperature, brightness of light and moistness of the air.
Evidence: According to the National Wildlife Foundation "Tree frogs can be a variety of colors, but most of the species found in the United States are green, gray, or brown. Some of them, like the squirrel tree frog (Hyla squirella), are chameleon-like in their ability to change color."
Reasoning: Other factors can cause the variation of colors in tree frogs, these can be used as defense mechanisms to protect or camouflage themselves among their surroundings

Start a discussion on Homeostasis. List facts and opinions, then compare and contrast.
Answer:
- Homeostasis is the ability of living systems to maintain a steady and uniform internal environment to allow the normal functioning of the systems.
- It is the tendency to achieve equilibrium against various natural and environmental factors.
- Homeostasis results in a dynamic equilibrium, where continuous changes keep on taking place, and yet steady conditions are maintained.
- Homeostasis is mainly involved in managing various internal variables of the living system like body temperature, pH of various fluids, the concentration of different ions, and the body sugar level.
- A number of regulatory mechanisms are employed to resist changes in the body against environmental and bodily factors.
- Homeostasis can be maintained by separate organs or by the entire body at once.
Maintaining homeostasis/Homeostasis Mechanisms
Homeostasis is maintained by a complex system that consists of individual units working in a particular sequence to balance a given variable. All homeostasis mechanisms consist of four separate units, which are:
1. Stimulus
The stimulus is something that results in changes within the system involving the variable.
The stimulus represents that the variable has moved away from its normal range, initiating the process of homeostasis.
One example of this is the increased temperature of the body above 37°C due to various causes. The increased temperature indicates that the temperature of the body has gone higher than its higher range.
2. Sensor/ Receptor
The sensor or receptor is the sensing unit of homeostasis, where it monitors and responds to the changes in the body.
The changes in the system are realized by the sensor, which then sends the information to the control unit.
The nerve cells and receptors like thermoreceptors and mechanoreceptors are examples of sensor/ receptors.
3. Control unit
Once the information is sent to the control unit, it tallies the changed value to its normal value.
If the value is different from the normal value, the control center activates the effectors against the stimulus.
The thermoregulatory unit in the hypothalamus of the brain that controls the temperature of the body is an example of the control unit.
4. Effector
Effectors can be muscles, organs, glands, or other similar structures that are activated as a result of the signal from the control unit.
An effector is a target which is acted upon by the control unit to bring the value of variable back to normal.
The effector essentially counteracts the stimulus to nullify its effect.
In the case of thermoregulation, the sweat glands are effectors that are acted upon by the thermoregulatory unit to produce sweat so as to bring the value of body temperature back to its normal value.
Crossing over occurs at the ends of chromosomes, rather than near the centromeres. As a result of crossing over, sister chromatids are no longer identical to each other. For crossing over to occur, homologous chromosomes must align precisely early in prophase I so that nonsister chromatids can exchange corresponding segments of DNA. Crossing over prevents homologous chromosomes from separating during meiosis I.

__________ is a method of studying complex systems by reducing the components that are studied (e.g. studying cells in culture and using those results to understand what is going on in a complex disease).
Select one:
a.
emergent properties
b.
systems biology
c.
genomics
d.
reductionism
Answer: A.
Explanation: "An emergent property is a property which a collection or complex system has, but which the individual members do not have. In biology, for example, heart is made of heart cells, heart cells on their own don't have the property of pumping blood. You will need the whole heart to be able to pump blood."
Explanation for the incorrect answer:
"Systems biology is the computational and mathematical analysis and modeling of complex biological systems. It is a biology-based interdisciplinary field of study that focuses on complex interactions within biological systems, using a holistic approach to biological research. "

Property of water that makes transpiration to occur
Answer:
cohesion
Explanation:
One of water's most distinctive properties is cohesion—that is, the tendency of water molecules to "stick" to one another. In plants, this cohesion results in columns of water that stretch through the plant's xylem, from the roots all the way to the leaves.

What is keeping Northern Europe from freezing? * 1 point O Warm water from the south is being carried across the North Atlantic Warm water from the south is being carried along the equator Cold water is coming south from the arctic Cold water is rising along the African Coast
Answer:The ocean is constantly in motion, moving water from place to place via currents. The Gulf Stream brings warm water from the Gulf of Mexico all the way up to the Norwegian Sea. As the warm water comes in, colder, denser water sinks and begins moving south—eventually flowing along the bottom of the ocean all the way to Antarctica.

Imagine that you are hiking and discover an outcrop of sedimentary rock. The rock is arranged in three distinct layers that appear to be undisturbed. When you examine the layers more closely, you observe fossils in the bottom and middle layers. What inferences can you make about these fossils based upon your observations and your knowledge of the law of superposition?
Answer:
The age of fossils are in millions.
Explanation:
These fossils were present on the earth millions of years ago due to different and unique structure of the fossil. The fossil is present in the bottom of the middle layer indicates that the more age of fossil i.e. millions of years according to the law of superposition. This law states that in an undisturbed layers of rocks, the top layer is the younger layer than middle and bottom layers which is older than the top layer, so we can say that fossils from deeper layers are older than fossils from the top layers of rocks.

Explain the relationships and trade-offs among amounts of skin pigmentation, Vitamin D production, and protection from UV radiation.
Answer:
Ultraviolet radiation leads to DNA mutations in the melanocytes, which are skin cells that contain melanin. Melanin level is inversely associated with the ability of skin cells to produce vitamin D
Explanation:
Ultraviolet (UV) radiation is a well-known environmental factor that causes mutations in the DNA of melanocytes, which are skin cells that produce melanin. Moreover, melanin is a protective pigment whose main function is to block UV radiation, thereby protecting the body from DNA damage and, consequently, from cancer (skin cancer). Abundant melanin levels can decrease the ability of the body to synthesize vitamin D, the only vitamin that can be synthesized with sunlight. In consequence, darker skin is associated with a higher risk of having vitamin D deficiency.
