Which of the following statements accurately describe variation in human skin color?
Data support a correlation between UV intensity and skin color variation.
Human skin color variation is mostly determined by the types and amounts of melanin present in the skin.
Variations in human skin color can be quantified, or measured.
On average, the skin color if indigenous peoples around the world correlates with UV intensity in their environments.
All of these are accurate.
Answer:
Melanin
Explanation:
Melanin is the name of the pigment in skin
The statement that accurately describe variation in human skin color is : ( B ) Human skin color variation is mostly determined by the types and amounts of melanin present in the skin
What is Melanin ?Melanin is a human substance which produces hair, eyes and skin pigmentation. The skin color of an individual is dependent on the amount of melanin produced by the body ( i.e the more melanin produced the darker the skin color )
Hence we can conclude that The statement that accurately describe variation in human skin color is Human skin color variation is mostly determined by the types and amounts of melanin present in the skin.

What would happen to an animal cell with an internal salt concentration of 0.8%
if it were placed in a salt solution with a concentration of 20%?
A. Not enough information to be able to tell
B. The cell would swell and burst
C. The cell would not be affected
D. The cell would shrink
Answer: The cell would swell and burst, because the 0.2% salt solution is hypotonic with respect to the cell, causing a net movement of water into the cell.
Explanation:
An animal cell with an internal salt concentration of 0.8% will shrink if it were placed in a salt solution with a concentration of 20%.
OSMOSIS:
Osmosis is the movement of water molecules from a region of higher concentration to a region of lower concentration via a semipermeable membrane. Movement of water in osmosis is based on concentration gradient i.e. difference on concentration of solute inside and outside the cell. Water will move from a cell with more water or less salt concentration i.e. the internal cell with 0.8% salt concentration to a solution with less water or more salt concentration i.e. 20% salt concentration. This will cause the cell to lose water to its external solution, and, hence, shrink.Learn more about osmosis at: https://brainly.com/question/264225?referrer=searchResults

Answer:
Algae has the most energy.
Explanation:
===================================================================
This is because it starts off at the bottom of the chain/level and is like a plant, which gets its energy from the sun.
Plants usually have the most energy in the trophic level, so in this case, its Algae.
When the organism is passed down the trophic levels, the energy gets cut (I forget the amount, it might be in half), so the Shark has the least among of energy in the trophic levels.

A. Atoms are added
B. It becomes less dense water

What are some of the natural factors that affect the loss and gain of wetlands in Louisiana?
.What industry contributes to wetland loss in Louisiana?
"The swamps and marshes of coastal Louisiana are among the Nation's most fragile and valuable wetlands, vital not only to recreational and agricultural interests but also the State's more than $1 billion per year seafood industry.What part of Louisiana is most in danger from land loss?
Dozens of reports show the highest rate of land loss occurred in areas with the heaviest amount of oil and gas extraction and canal dredging, Marshall says. According to some studies, the oil and gas industry is responsible for anywhere between 36 to 60 percent of the loss.
Answer:
Natural factors that can cause the loss and gain of wetlands in Louisiana are hurricanes, drought, salt water moving inland, subsidence, and rise in sea levels.

An environmental toxin is discovered that interferes with certain
cellular functions. When affected cells are examined, it is observed that
proteins that are normally found on the plasma membrane are instead found in
the cytoplasm. Other proteins are also located improperly. Which structure is
most likely affected by the toxin?
A
lysosome
B mitochondria
С
cell wall
I
D
Golgi apparatus
Answer:
Golgi apparatus
Explanation:
The Golgi apparatus is an organelle found in most eukaryotic cells, i.e. cells with a clearly defined nucleus. The purpose of the Golgi apparatus is to transport, modify, and package proteins and lipids. If a cell affected by an environmental toxin ended up with misplaced proteins, we could conclude that the organelle that is no longer functioning properly is the Golgi apparatus.

Carbohydrates are usually composed of sequences of carbon (C), hydrogen (H), and oxygen (O). How do proteins differ from carbohydrates?
A All proteins contain iron (Fe).
B. All proteins contain helium (He).
All proteins contain nitrogen (N).
D.
All proteins contain potassium (K).
Answer:
Structurally, proteins are different from carbohydrates because all proteins contain nitrogen (option C).
Explanation:
The basis of the chemical composition of proteins is carbon, hydrogen, oxygen and nitrogen, so all proteins have nitrogen in their structure. Some proteins also possess phosphorus and sulfur atoms, among others.
Proteins are biomolecules formed by the union of multiple amino acids through carboxyl-amino bonds, called petidic bonds. Their content of nitrogen and other atoms in their structure is what makes them different from carbohydrates.
The other options are not possible because:
Only some proteins contain iron in their composition.Potassium and helium are not part of the protein structure.Researchers returning from the world’s most ambitious study ever of the

How is biodiversity regulated in a system?
Answer & Explanation:
Biodiversity is regulated primarily by weather in addition to many other factors. Weather changes can cause droughts or flooding. Weather often pushes main species to migrate and therefore cause new biodiversity, indirectly the migration of one species into a new region could cause that new species to consume the already thriving species already in existence which then could reduce the value of species diversity in that region and throw off the pre-existing ecosystem.

All living things need energy to survive. The most common source of energy for organisms is glucose molecules, which are used as food. A plant’s food is no exception. Where do plants get the carbon needed to make glucose molecules during the process of photosynthesis?
from the ground.
from the air.
from the water.
from the sun.
Answer:
the air
Explanation:
Plants get the carbon from the air which are needed to make the glucose molecules during the process of photosynthesis in plants. Thus, the correct option is B.
What is Photosynthesis?Photosynthesis is the process of formation of carbohydrate (sugar) in the green leaves of plants. This process takes place in the presence of light. In this process, the light energy (solar radiation) is trapped in the chlorophyll pigment present in the green leaves of plants, this energy is converted into chemical energy in the form of glucose (carbohydrate) which is used by the plants in various processes.
The reaction includes the reaction between carbon dioxide and water molecules which are present in the air to produce glucose and oxygen gas which are consumed as food and in the process of respiration.
Therefore, the correct option is B.

How does biodiversity reduce one species’ dependence on another species? Explain, and provide an example.
Answer:
For example, two animal predators may consume different prey items, so they are less likely to compete with one another, allowing higher total biomass of predators in the system. In the case of plants, all species may utilize the same suite of resources (space, light, water, soil nutrients, etc.)
Explanation:
The presence of large biodiversity can reduce one species dependence on another species as it provides resources such as food which will reduce the chances of a species to become threatened.
What is biodiversity?Biodiversity can be defined as the variety of all the different kinds of organisms such as the plants, animals, insects and microorganisms which live on the planet.
A large biodiversity is helpful for the species as it increases the stability of the ecosystems. This is possible because it reduces the dependence of one species on another, for the instance for food. For example, if a species has only one food source, it may be easily threatened by the environmental changes. However, if many species similar to it are present in the ecosystem then the chances of the species to become threatened are very low.
