Describe why biodiversity increased with the introduction of sea otters in California over the last fifty years
Answer:
Due to increment in food chains.
Explanation:
Biodiversity is actually the measure of changes in the ecosystem, genetic levels and various species levels. The sea otters introduced in California over last fifty years, increased the diversity in the ecosystem as well as in species too, thus changing the biodiversity. This was the impact of increase in food web in that particular area, the number of consumers, producers and prey increased thus increasing the biodiversity.
Which feature is characteristic of healthy coral reefs?
A. Shallow, clear water
B. Clear freshwater
C. Deep, salty water
D. Cold, murky water
Answer:
Answer A
Explanation:
The correct answer is option A, that is, shallow and clear water. Coral reefs refer to the shallow-ocean habitats, which are occupied with sea life. The massive composition that coral reef comprises of is actually manufactured of coral polyps that are the small marine species, which live in colonies.
The hard compositions are left behind when these marine species die, and the branching and stony composition, which is left is limestone and is robust enough to produce a home for new species.
Healthy coral reefs are characterized by shallow, clear water and high biodiversity. The organisms living in the reefs have a mutualistic relationship with photosynthetic unicellular algae, which provide them with nutrition and energy. This clear water allows light to penetrate, supporting the growth of both corals and algae.
Explanation:Coral reefs are ocean ridges formed by marine invertebrates living in warm shallow waters within the photic zone of the ocean. They are mostly found within 30 degrees north and south of the equator. Coral reefs are characterized by high biodiversity and the structures created by the invertebrates that live in them. They provide nourishment and shelter for a wide variety of species, including over 4,000 fish species.
Shallow, clear water is characteristic of healthy coral reefs. The organisms living in these reefs have a mutualistic relationship with photosynthetic unicellular algae, which provide them with nutrition and energy. The clear water allows light to penetrate, allowing the algae to carry out photosynthesis and the corals to thrive.

what minimum internal temperature must the salmon reach cooking
Answer:
145 degrees
Explanation:
Because the united states food and drug administration recommends cooking salmon to an internal temperature of 145 degrees Fahrenheit. Push the tip of the meat thermometer gently into the middle of the salmon fillet at its thickest part.
Salmon should be cooked to a minimum internal temperature of 145°F, as measured by a food thermometer, to ensure it is safe to consume.
When preparing salmon, it is essential for safety and health to ensure the fish is cooked to the appropriate internal temperature. According to the USDA and food safety guidelines, seafood, including salmon, should be cooked to a minimum internal temperature of 145°F. This temperature should be measured using a food thermometer to confirm that the salmon has reached the temperature sufficiently high enough to kill harmful bacteria that can cause foodborne illnesses. Additionally, it's important to make sure that when cooking fish in a microwave oven, there are no cold spots where bacteria can survive. For even microwave cooking, cover the seafood, stir, rotate, and if no turntable is present, manually rotate the dish once or twice during cooking.
which information must be known about a compound to find the molecular formula from the empirical formula
Answer:
Molecular mass or vapor density
Explanation:
The empirical formula is the simplest formula of a compound. The molecular formula expresses the exact formula of the compound. To derive the molecular formula, we need information about its molecular mass or if given the vapor density.
(Empirical Formula)n = Molecular formula ------(i)
n = number of repeating units of the empirical formula present in one mole of the molecule
also, (molar mass of empirical formula)n = molar mass of compound
From here, we can find n and insert in (i) above.

What is the most likely explanation for how speciation occurs?
A)It occurs only by gradual changes.
B)It occurs only by geographic isolation.
C)It occurs only by natural selection.
D)It occurs by more than one method.
Answer: D
Explanation: Speciation is process in which new and distinct species are formed over a course of time.
It occurs by many means:
1) Gradual Changes- every species undergo some molecular changes with inheritance and eventually leads to formation of an all new species.
2) Geographic isolation- with isolation into a different geographic area, the species try to adopt with the geography and ultimately forms different species. Eg. Australian marsupials.
Why is the fossil record incomplete? Choose all that apply.
Not all organisms are fossilized.
Not all scientists believe in the fossil record.
Not all fossils survive.
Not all fossils are found.
Answer:
The fossil record, however, is quite incomplete. Here's one major reason why: Sediment has to cover an organism's remains in order for the long fossilization process to begin. Most organisms decompose before this can happen.
Answer:
Not all organisms are fossilized. Not all fossils survive.Not all fossils are found.Explanation:
The most direct way to determine the age of a species is to observe in the fossil record what was the first occurrence of this species. The biggest problem is that the fossil record is very incomplete, because many times organisms decompose before being fossilized, and many fossils have never been found. In short, we can say that the fossil record is incomplete because not all organisms are fossilized, not all fossils survive and not all fossils are found. Moreover, the fact that one finds fossils of a species from a certain age does not mean that such a species originated at that time in geological history. It may be that records of the species's presence in previous ages have been lost.

How can one tell if a reaction has reached equilibrium?
O
A. The reaction starts to go in the reverse direction.
B. The concentrations of products and reactants stop changing.
O
C. The concentrations of products and reactants are equal.
O
D. The reaction stops once the reactants have been used up.
A chemical reaction reaches equilibrium when the concentrations of products and reactants stop changing, which corresponds to the forward and reverse reactions occurring at equal rates, making the system's reaction quotient (Qc) constant. This is known as dynamic equilibrium.
Explanation:To determine if a reaction has reached equilibrium, one looks for a state where the concentrations of products and reactants stop changing. Despite the absence of visible changes in concentrations, both the forward and reverse reactions are still occurring at equal rates. This does not imply that the amounts of reactants and products are equal, but that they are constant due to the equal rates of the forward and reverse reactions represented by a double-headed arrow, as in A+B=C+D. During the approach to equilibrium, you'll observe that the reaction quotient (Qc) changes as product and reactant concentrations change; once equilibrium is reached, Qc remains constant.
Dynamic equilibrium is a term used to describe this state. It may seem as if the reaction has stopped, but in reality, the system is dynamically balanced with the forward rate of forming products (C & D) being equal to the rate of the reverse reaction of these products turning back into reactants (A & B).

Why do some codons code for the same amino acid as another codon?
A. it is due to mutations.
B. There are only 20 amino acids and 64 possible combinations
C. Each codon is unique and they all code for different amino acids.
Answer:
B
Explanation:
i think it is b, because if they have 20 amino acid, 64 possible combination
they will be able to combine between themselve
Answer:
B. There are only 20 amino acids and 64 possible combinations
Explanation:
The genetic code is degenerate this means that more than one codon codes for a single type of amino acid.This degeneracy occurs because there are 64 possible triplets of the bases that exist however there are only 20 amino acids known to encoded by the genetic code. Out of this 64 possible triplet codons, 61 triplets are responsible for coding the amino acid whereas three of them form a stop codon that helps terminate the translation.wich of the following is an example of an epeirogenic process
Answer:In geology, epeirogenic movement (from Greek epeiros, land, and genesis, birth) is upheavals or depressions of land exhibiting long wavelengths and little folding apart from broad undulations. The broad central parts of continents are called cratons, and are subject to epeirogeny. PLZ HELP ME FOR MATH!!! go to my profile and plz try answer my question, but if you dont get it plz dont answer!!!
Explanation:
The following is an example of an epeirogenic process is A large plateau forms in the interior of a continental plate when a large section of the plate rises evenly due to an even expansion of the underlying mantle.
The correct option is (C).
1. Epeirogenic processes involve broad-scale vertical movements of the Earth's crust, typically affecting large areas of continents rather than localized regions.
2. Unlike orogenic processes (which involve the formation of mountains through folding, faulting, and volcanic activity), epeirogenic processes result in more gradual changes in elevation over large regions.
3. The formation of large plateaus, such as the Colorado Plateau in the United States or the Deccan Plateau in India, is an example of epeirogenic uplift.
4. This uplift occurs when large sections of the continental crust rise evenly due to processes such as isostatic rebound or mantle convection.
5. Isostatic rebound refers to the adjustment of the Earth's crust in response to changes in surface loads, such as the melting of glaciers or the erosion of mountain ranges, leading to the uplift of previously depressed regions.
6. Mantle convection can also drive epeirogenic uplift by generating upward flow within the Earth's mantle, resulting in the buoyant uplift of continental crust.
7. Overall, epeirogenic processes contribute to the formation of large-scale topographic features such as plateaus, which play important roles in shaping the landscape and influencing regional climates and ecosystems.
complete question given below:
Which of the following is an example of an epeirogenic process? A. Mountains form along a convergent plate boundary when two plates collide, causing rock to bunch and buckle upward B. A rift valley forms at a divergent boundary where two plates are stretched apart. C. A large plateau forms in the interior of a continental plate when a large section of the plate rises eventy due to an even expansion of the undertyng mantle D. Mountains form along a convergent plate boundary when an oceanic plate slips beneath a continental plate, resuling in an upward force on the continental plate.

The two options that could potentially be considered 'benefits' of climate change are increased demand for building construction due to adaptation needs and increased crop growth in some regions due to warmer temperatures.
Explanation:While climate change is generally viewed as a global problem with significant negative impacts, there are indeed a few potential 'benefits' that might occur. However, it is important to note that these potential benefits are often far outweighed by the potential harm.
In terms of your options, the two that could be considered potential benefits of climate change are:
B. Increased demand for building construction and E. Increased crop growth.
As sea levels rise and temperatures change, there may be an increased demand for building construction to adapt to these changes. This could also stimulate economic activity.
Warmer temperatures can also lead to longer growing seasons in some regions, potentially increasing crop growth. However, this is a complex issue and the overall impact on agriculture is likely to be negative due to factors such as increased drought and unpredictable weather patterns.

Read the paragraph. Then answer the question that follows. Perhaps you wanted pizza for dinner, but were out voted by the rest of the family who wanted chili. This is similar to what happens in a community. One person has to give up a right for the good of the group. Sometimes citizens' duties and rights conflict with each other. A good example is a public protest. People have the right to meet in groups and share ideas. However, a protest can disrupt traffic or other normal activities. A city must provide extra police protection to keep people safe. Therefore, the city has the right to require permission in advance for a protest. Government must make laws to balance the rights of individuals and different groups of people. Which of the following statements best describes this paragraph?

Explanation:
Based on the above provided excerpt, we can see that the passage is an analogy on the two sides of every action. Just like the need to sacrifice the minority opinion for the majority, so is the same case for any protests or dissensions in a society.
Analogies provide comparisons between things for the better explanation of the issues concerned. By comparing the majority and minority opinions through the examples of "family pizza", " protests"or even "community rights", the author makes it a point to show the two sides of any story. Of course both opinions matter but for the sake of a democratized and equal footing of the two parties, there had to be some compromises made. And this is exactly what the analogy does. The analogy makes it perfectly understandable for the readers.
