After carefully watching the video, choose THE BEST Claim in regards to why human skin color varies throughout the world.



A. Primates have light skin color under their dark hair so when humans began to evolve and lose body hair, that pigment needed to go into their skin so they could still blend in with their surroundings.


B. Darker melanin is beneficial for reproduction in areas where ultraviolet (UV) light is high, and can negatively affect reproduction in areas of low UV light.


C. Darker melanin is beneficial under intense UV light because it protects from skin cancer, absorbing the UV light. Under low UV light, producing excess melanin uses too much energy, therefore it is more beneficial (energy saving) to produce less melanin in low UV light areas.


D. Humans evolved as separate populations, around the equator and towards the poles, so skin pigment color (melanin) was naturally different in those areas

Answer: no

Explanation:

because  some plants rely on photosynthesis to survive and they use the suns energy for that but if something does not photosynthesize then it gets energy from food.

Answer:

Eutrophication effect

Explanation:

The term eutrophication refers to the enrichment of surface water with nutrients. This process is related to human pollution activities.

Eutrophication is the biological process that generates in water by an oversupply of nutrients or organic matter. This matter, mainly compounded with nitrogen or phosphorous, favors the multiplication of phytoplankton (microscopic plants growing on the water surface) and other aquatic plants. This overgrowth leads to an enhance in primary productivity.

Little by little begin sedimentation, caused by the death of some vegetable organisms that sink in the bottom. These sediments rich in organic matter suffer decomposition in the presence of oxygen.

When oxygen disappears, anaerobic bacteria act and produce fermentation.

On the surface, plants and phytoplankton keep growing, creating a mantle that impedes the light to reach deeper areas. The overgrowth of phytoplankton on the water surface and the fermentation processes in the bottom originate toxic compounds that damage the animals. Animals die, creating more sediments in the bottom where there are anaerobic conditions. Decomposing processes and fermentation increases, producing a bad smell.

The result of eutrophication is the stratification of the water mass:

Answer:

Only blue light reaches deep into the ocean.

Explanation:

Coral reefs exist in waters less than 50 m to 2000 m deep while Red algae have been found living in depths of over 500 feet because both coral reefs and red algae needs blue light for photosynthesis. In the deep sea or ocean, only short wavelength such as blue light reaches deep in the ocean floor while long wavelength light such as red unable to reach so that's why both coral reefs and red algae present and distributed on the ocean floor.

'Chemosynthesis' basically is the process which a bacteria living near a heat vent on the ocean floor use to build carbon-based molecules, such as sugars.

What do you mean by Chemosynthesis?

Chemosynthesis is a process by which some organisms use chemical energy to produce carbohydrates. This process occurs in environments where sunlight is not available, such as deep-sea hydrothermal vents. Organisms such as bacteria and other microbes convert chemicals such as hydrogen sulfide and methane into energy, which they use to produce organic molecules such as glucose.

The bacteria living near hydrothermal vents on the ocean floor use chemosynthesis to build carbon-based molecules, such as sugars, from the hydrogen sulfide and other chemicals that are spewed from the vent. The bacteria use the energy from the chemical reaction to form carbohydrates from the chemical reaction, which are then used as a source of energy for the bacteria. This process is thought to be the first form of energy production for life on Earth, and is seen as an important part of the global carbon cycle.

Hence, option D is correct.

Environmental policies are an essential tool for reducing the negative impacts of human activities on the environment. Incentive-based environmental policies are designed to encourage individuals and companies to take actions that are environmentally friendly. There are two types of incentive-based environmental policies, which are market-based systems and tax/subsidy programs.

Market-based systems are policies that create a market for environmentally friendly products or services. These systems allow companies to buy and sell pollution permits, which give them the right to emit a certain amount of pollutants. Companies that emit less than their allotted amount can sell their excess permits to companies that emit more than their allotted amount. This creates an incentive for companies to reduce their emissions, as they can make money by selling their excess permits.

Taxes/subsidy programs are policies that create financial incentives for individuals and companies to take environmentally friendly actions. Taxes can be imposed on activities that harm the environment, while subsidies can be given to activities that benefit the environment. For example, a tax could be imposed on companies that emit pollutants, while a subsidy could be given to companies that produce renewable energy.

Technology standards are policies that set minimum requirements for the technology used in certain industries. These standards can help to reduce the environmental impact of certain industries by requiring them to use more efficient and less polluting technologies. Emissions standards are similar to technology standards, but they set limits on the amount of pollutants that can be emitted by certain industries.

In conclusion, there are two types of incentive-based environmental policies, market-based systems and taxes/subsidy programs. Technology standards and emissions standards are also important policies that can help to reduce the negative impacts of human activities on the environment. By implementing these policies, we can create a cleaner and more sustainable world for future generations.

animal cell works differently than plant cell

animal cell have million of cell as well plant..

animal cell have four key part ..plant cell have cell wall,chloroplasts, vacuoles

Explanation:

Plant cells have a cell wall, but animals cells do not. Cell walls provide support and give shape to plants.

Plant cells have chloroplasts, but animal cells do not. Chloroplasts enable plants to perform photosynthesis to make food.

Plant cells usually have one or more large vacuole(s), while animal cells have smaller vacuoles, if any are present. Large vacuoles help provide shape and allow the plant to store water and food for future use. The storage function plays a lesser role in animal cells, therefore the vacuoles are smaller.

The correct phrase for the word is the following:

Coal: sediment, rock, and water apply pressure and heat to plant remains.

Oil: formed at the bottom of the ocean where sediment, rock, and water apply pressure and heat.

Natural gas: made mostly of methane.

Natural gas, when extracted, can contain a range of elements and molecules other than methane. A natural gas well may contain water, ethane, butane, propane, pentanes, hydrogen sulfide, carbon dioxide, water vapor, and, on rare occasions, helium, and nitrogen.

The correct answer is "microvilli." Microvilli are microscopic, finger-like projections that extend from the apical surface of cells in a simple columnar epithelium. These small structures greatly increase the surface area available for absorption and play a crucial role in enhancing the efficiency of nutrient absorption along portions of the digestive tract.

Within the digestive tract, the simple columnar epithelium lines the surface of organs like the small intestine and large intestine, where nutrient absorption occurs. The presence of microvilli on the surface of these epithelial cells provides numerous benefits for efficient absorption.

Firstly, the abundance of microvilli significantly increases the total surface area available for absorption. This increased surface area allows for a greater contact between the luminal contents (such as digested food) and the absorptive cells, maximizing the absorption of nutrients like carbohydrates, proteins, and fats.

Secondly, the microvilli contain specialized transport proteins and channels that facilitate the absorption of specific molecules. These proteins help transport nutrients across the epithelial cells and into the bloodstream or lymphatic system. The dense packing of microvilli amplifies the presence of these transport proteins, further enhancing absorption efficiency.

Additionally, the microvilli possess a brush-like appearance due to their close arrangement. This brush border aids in trapping and retaining the digested food particles and nutrients, preventing their rapid movement through the digestive tract. This allows for sufficient time for absorption processes to occur.

In contrast to microvilli, cilia are hair-like structures present on certain types of epithelial cells. While cilia have important functions like moving mucus and facilitating the movement of substances, they are not directly involved in absorption along portions of the digestive tract.

Therefore, the modification of the simple columnar epithelium that enables efficient absorption along portions of the digestive tract is the presence of microvilli.

Choroid plexus cells are ependymal cells that have been modified to surround the capillary loops that produce cerebrospinal fluid (CSF).

The choroid plexus is a complex network of capillaries lined with specialized cells that perform a variety of functions. One of its main functions is the production of cerebrospinal fluid (CSF) via the ependymal cells that line the ventricles.

Choroid plexus epithelial cells secrete cerebrospinal fluid (CSF) by a process involving the transfer of Na(+), Cl(-), and HCO(3)(-) from the blood to the ventricles. This creates an osmotic gradient that promotes H(2)O secretion. A network of blood vessels and cells within the ventricles (fluid-filled spaces). Blood vessels are lined with a thin layer of cells that form the cerebrospinal fluid.
