Explanation:
The main difference between Submergent coastlines and emergent coastlines because Submergent coastlines formed when sea level rises or in other words, the land sinks down. Examples of submergent coastlines are estuaries, barrier bars, and barrier island systems while on the other hand, emergent coastlines occurs when sea level drops or the land rises.

A is the answer
Earth scientists have concluded that the methods of harnessing energy that have been used over the past two centuries, such as the burning of fossil fuels, are causing climates around the world to change more quickly and suddenly than ever before in human history. Evidence includes increased air temperatures, rising sea levels, and the shrinking of glaciers in Greenland, Alaska, and other regions of Earth.

The most complex level of organizational hierarchy that climate change could potentially affect is Earth's biosphere.
What is biosphere?
The biosphere refers to the global ecological system that encompasses all living organisms and their interactions with the physical environment. It includes various interconnected ecosystems, such as forests, oceans, grasslands, and deserts, along with the diverse array of species and their habitats.
Climate change, with its wide-ranging impacts on temperature, precipitation patterns, and other environmental factors, can disrupt ecosystems and alter the distribution and abundance of species within the biosphere. These changes can have cascading effects on communities of organisms, populations of species, and the overall functioning of ecosystems. Therefore, the biosphere represents the highest level of organization that climate change can potentially impact.

For each phrase below, choose the most appropriate key term from the list above
a. The improper or unsafe use of a drug
b. A drug that is inhaled as vapors
c. a drug that temporarily increases energy and alertness
d. drug withdrawal occurring in newborn infants
e. laboratory made drugs that closely resemble common illegal drugs in chemical structure and effect
f. a drug that slows the body and the brain
Answers
Answer:
a. Drug abuse
b. Inhalants
c. Stimulants
d. Neonatal abstinence syndrome
e. Club designer drugs
f. Depressants
Explanation:
Drug abuse can be defined as the excessive use of drugs that can be harmful to the individual or to others, which is associated with social, behavioral, physical and job-related problems. Inhalants drugs (e.g., glue, cocaine) are volatile drugs whose inhalation may induce psychoactive and/or mind-altering effects. Stimulant drugs (e.g., cocaine, amphetamines) are drugs that excite body functions by accelerating the activity of the central nervous system (CNS), while depressant drugs (e.g., alcohol) slow down the CNS. Neonatal abstinence syndrome occurs when a neonate withdraws from certain drugs (usually opioid drugs which interact with opioid receptors) to which he/she was exposed before birth. Finally, designer drugs (e.g., ecstasy, ketamine, LSD) are drugs synthesized in illegal labs which are commonly known as “club drugs” because they are often used and sold in nightclubs.

where does osmosis take place
Answers
Answer:
In Gastrointestinal system:
When we eat food or drink water, it travels from our mouth, down our oesophagus and into our stomach. In the stomach, the food is broken into tiny pieces that are mixed with stomach liquids. This mush of food and stomach liquids is called chyme. The chyme travels into the small intestine. This is where osmosis takes place.
In our Kidneys:
Our kidneys keep blood and tissue fluid (internal environment) 'clean' by removing urea, excess water and other wastes and excreting them. This controls the amounts of dissolved substances in blood and tissue fluid, a process called osmoregulation. If tissue fluid becomes too concentrated, cells will lose water by osmosis and become dehydrated and if it becomes too dilute, cells will take in excess water by osmosis.
Scientists often look for similar genes in very dissimilar organisms as evidence that they are related.

1. Why should we care that the panthera tigris is going extinct? Explain how humans might be affected by the loss of the panthera tigris.
Answers
Answer: I believe tigers, also known as "Panthera tigris" are important to humans because they balance the ecosystem. When creatures go extinct they leave behind a scar that affects the ecosystem that is around them. Since Tigers are secondary consumers they control natural prey populations. The connection to the food web is very important and essential to keep this food web stable. Once something goes extinct it will cause the food web to shift and some primary producers will go out of control.
Explanation: Not sure if this helped at all this is just what I know about the food web. Panthera Tigris are secondry consumers so they control the primary producer population. This is just basic food web and ecosystem thinking. This is how they impact humans if they go extinct.

The Pearson Correlation Coefficient is a tool used in understanding the behavior of gene expression. A positive ratio means a gene is induced in cancer cells and is transcribed at a higher rate. A negative ratio means a gene is suppressed in cancer cells or is transcribed less frequently than in normal cells. What form of gene expression do you think would lead to a correlation coefficient of one
Answers
Answer:
the gene is being expressed at an equal rate in both cell types
Explanation:
In statistics, the Pearson correlation is a linear measure of the association between two continuous variables. The Pearson's Correlation Coefficient may exhibit values between -1 and +1. A value equal to 1 shows a perfect correlation, indicating that when one variable increases the second variable also increases (when this value is +1) or decreases (when this value is -1). Moreover, when the Correlation Coefficient is equal to 0 it means that there is no correlation.
