what would be the independent, dependent, and control variable to how coral dies? (100 points)
Answer:
in the explanation
Explanation:
The independent variable would be us humans polutling the ocean with oil and other plastics destroying the coral reefs. The dependant variable is an abbrasive species of fish becoming overpopulated and killing all the fish that help the coral grow causing the coral to die. (independant variable basically means humans tampering with it causing the problem. dependent is naturally occuring humans cant control whether a fish overpopluates or not thats natural)

Parasitism is the type of symbiosis that occurs between a deer and the tick. So, the correct option is C. This is because bacteria infect their host cell which is found in Deer.
What do you mean by Symbiosis?Symbiosis may be defined as a relative ecological association between the individuals of two or more different species.
The type of symbiotic relationship found between oxpecker and zebra is Mutualism. This is because oxpecker is able to get its prey (food), while zebra is benefitted from the removal of insects from their body. So, the correct option is A.
The type of symbiotic relationship between Humans and bacteria living in their digestive tract is Mutualism. This is because Humans are benefitted from bacteria as they assist in digesting food, while bacteria also benefit to find a proper place where unlimited food is available. So, the correct option is A.
The type of symbiotic relationship between Barnacles and whales is Commensalism. This is because Barnacles are benefitted from excess food and easy transportation, while whales are neither benefitted nor harmed by this relationship. So, the correct option is B.
Therefore, each of the questions are properly described above.

how will climate change affect the habitat distribution for the baltimore oriole?
Climate change has a great effect on the habitat distribution of Baltimore orioles bird.
Climate change will adversely affected the habitat distribution of Baltimore orioles because climate change causes heat waves, wildfires and intense downpours which is harmful for Baltimore orioles.
The climate changes will limit the populations of ranges of Baltimore oriole as well as changes the habitat. These Baltimore orioles moved to other places where the climate is favourable so we can conclude that climate change has a great effect on the habitat distribution of Baltimore orioles bird.

How do human beings affect the carbon dioxide and oxygen cycle?
Answer:
Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere. The ocean absorbs much of the carbon dioxide that is released from burning fossil fuels.
Answer:
By breathing.
Explanation:
Humans inhale oxygen, and when they need to release it, (exhale) that oxygen is no longer oxygen and is now carbon dioxide. Trees and plants are what helps oxygen to exist in our world even though we breathe it in and convert it to carbon dioxide. Hope this helps ^^

in a neuron, sodium and potassium concentrations are maintained by the sodium-potassium exchange pump such that __________.
Answer:
the sodium concentration is higher outside the cell than inside the cell and the potassium concentration is higher inside the cell than outside the cell.
Explanation:
In a neuron, sodium and potassium concentrations are maintained by the sodium-potassium exchange pump such that the sodium concentration is higher outside the cell than inside the cell and the potassium concentration is higher inside the cell than outside the cell.
What is sodium potassium pump?The sodium potassium pump contributes to the maintenance of osmotic equilibrium and membrane potential in cells. Sodium and potassium move in the contrast way of the concentration gradients.
The Na+ K+-ATPase pump establish and maintain a gradient of higher sodium concentrations extracellularly and higher potassium levels intracellularly.
The sodium-potassium pump is critical to the proper functioning of neurons. It aids in the maintenance of ionic concentrations both inside and outside the cell, allowing neurons to fire action potentials, which is the basis for electrical signaling within neurons.
The sodium-potassium exchange pump maintains sodium and potassium concentrations in neurons so that the sodium concentration is higher outside the cell than inside the cell and the potassium concentration is higher inside the cell than outside the cell.
Thus, this way, sodium and potassium concentrations are maintained by the sodium-potassium exchange pump in a neuron.

(A) Birds are endothermic and have four-chambered hearts, while reptiles are ectothermic and have three-chambered hearts.
Explanation:
got it right on the test
Birds and reptiles both belong to the animal kingdom. Reptiles are ectothermic and have three-chambered hearts, whereas birds are endothermic and have four-chambered hearts. Thus, option A is correct.
What are the characteristics of birds and reptiles?Birds and reptiles both belong to the kingdom Animalia and are chordates. They both have vertebral columns and the presence of the backbone. They share many similarities and differences in their physical appearances.
The birds are endothermic and can maintain constant body tempearture regardless of the external environment. While reptiles are ectothermic (cold-blooded) and regulate their temperature based on the external environment.
The birds have four-chambered hearts like mammals that separate the oxygenated from the de-oxygenated blood, whereas the reptiles have three-chambered hearts with one ventricle and two atria.
Therefore, the birds are endothermic, and reptiles are ectothermic.

Even though human proteins are made from only 20 different amino acids, there are thousands of differen proteins found in human cells. What allows for so much variation in the proteins?
Answer:
Amino acids are the basic building blocks of proteins, and they serve as the nitrogenous backbones for compounds like neurotransmitters and hormones. In chemistry, an amino acid is an organic compound that contains both an amino (-NH2) and carboxylic acid (-COOH) functional group, hence the name amino acid. Proteins are long chains or polymers of a specific type of amino acid known as an alpha-amino acid. Alpha-amino acids are unique because the amino and carboxylic acid functional groups are separated by only one carbon atom, which is usually a chiral carbon. In this article, we will solely focus on the alpha-amino acids that make up proteins
