Are all animals that share a food source classified in the same trophic level
ANSWER QUICK PLEASE!!!
Answer:
it depends on the food web that the animal is on but they can sometimes
Explanation:
Answer:
An organism may not always occupy the same trophic level, depending on the food web. Assigning organisms to trophic levels isn't always clear-cut. For instance, humans are omnivores, meaning they can eat both plants and animals. So they may be considered both primary and secondary (or even higher!)

What part of speech is the word mission in the sentence below?
My mission was to get the cat out of the tree safely.
noun
verb
adverb
adjective
A student has two beakers (Beaker X and Beaker Y) of clear unknown liquids. The student knows that one liquid is a weak acid and one is a weak base. She knows that both liquids are equally concentrated as either an acid or a base. The student also knows that the pH of the liquid in Beaker X is 8. Therefore, the student concludes that Beaker X contains the acid and Beaker Y contains the base.
1) State whether or not the student’s conclusion is correct.
2)Explain your answer.
3)Describe the likely outcome in terms of acids, bases, and buffers, if the liquids in
Beaker X and Beaker Y were combined.
Answer: Y E S
Explanation:
A weak conjugate acid-base pair, which can be either a weak acid and its conjugate base or a weak base and its conjugate acid, must make up a buffer in order to maintain a pH range properly.
What is meant by buffer solution?A buffer is a substance that can withstand a pH change when acidic or basic substances are added. Small additions of acid or base can be neutralized by it, keeping the pH of the solution largely constant.
For procedures or reactions that call for particular and stable pH ranges, this is significant. The pH range and capacity of buffer solutions determine how much acid or base can be neutralized before pH changes and how much pH will vary.
A weak conjugate acid-base pair, which can be either a weak acid and its conjugate base or a weak base and its conjugate acid, must make up a buffer in order to maintain a pH range properly. The pH that is desired while making the buffer will simply determine which should be used.
1) As the pH of beaker X is 8 it must be base, the student's conclusion is not correct.
2) Acidic pH values are those below 7, while alkaline pH values are those above 7 (basic).
3) If the liquids combine they create a buffer solution as a buffer exists made by combining a large volume of a weak acid or weak base with its conjugate.

many pathogenic bacteria species are bcoming resistant to antibiotics. explain how such adaptions can develop through the process of natrual selection
Answer:
Antibiotic resistance evolves naturally via natural selection through random mutation, but it could also be engineered by applying an evolutionary stress on a population. ... The antibiotic action is an environmental pressure; those bacteria which have a mutation allowing them to survive will live on to reproduce.

In what way is surface area more important for cells than volume?
Answer:
As a cell grows in size, the surface area gets bigger, but the volume gets bigger faster. Thinking about this as a ratio (division), the volume is the denominator and the surface area is the numerator. If the volume is getting very big, then the ratio itself will be getting very small.

Explanation:
If purple flowers are dominant in a plant and white flowers are recessive in that plant, then when purple-flowered
plants with two dominant genes are mated with white-flowered plants with two recessive genes, the first
generation of offspring should have
A
100% white flowers
B
75% purple flowers and 25% white flowers
с
50% purple flowers and 50% white flowers
D
100% purple flowers
im pretty sure it would be c
If purple-flowered plants with two dominant genes are mated with white-flowered plants with two recessive genes, the first generation of offspring should have 100% purple flowers.
Genes are defined as units of inheritance that occur in the chromosomes. Usually, genes occur in pairs called alleles and these alleles control the expressed traits (phenotype) of an organism.
In this case, we have a flowering plant having a dominant gene for purple flowers (R) and a recessive gene for white flowers (r). Using a punnet square, we can see that the first generation will have all purple flowers since it is the dominant gene as shown.

Living things obtain matter from their environment and release waste back into it. This matter moves in a cycle. Plants use air, water, nutrients, and sunlight to make food and grow. Some animals eat the plants and use their matter to grow. When those animals die, decomposers will grow using the matter from the animals' bodies. The decomposers release this digested matter back into the air and soil. The matter in an ecosystem is recycled. Gases are a type of matter that moves through an ecosystem. For example, oxygen and carbon dioxide are cycled between organisms and the air. The producer in the diagram takes carbon dioxide from the air. It uses this gas and water to make sugar, releasing oxygen as waste. Then the consumer breathes in the oxygen and uses it in its body. It also eats the producer for food, represented as carbon in the diagram. The decomposer takes oxygen from the air and food from the consumer or producer. The consumer and decomposer make carbon dioxide, putting it into the air. When producers use it again, the matter is recycled. Describe in words how carbon and oxygen move through an ecosystem. (my little bro needs help and I am to lazy to do it)
Answer:
"living things obtain matter from their environment and release waste back". plants use carbon dioxide, then let out oxygen for us to use. When animals die, decomposers release the digested matter back into the air and soil. Different types of gases move throughout a ecosystem and is recycled between organisms and air. (again going back to the air recycled between a plant and a human).
Answer:
the decomposers release carbon dioxide that help plans grow then they can do photosynthesis then the oxygen is given to animals then they die then decompose and that's a cycle

1. What is science? 2. Name the three branches of science. 3. What is the universe? 4. What is nature? 5. Define biology, chemistry, and physics? Explain how they are related to science?
Answer:
1-Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe. The earliest roots of science can be traced to Ancient Egypt and Mesopotamia in around 3500 to 3000 BCE.
2-The three branches of Science include Physical Science, Earth Science, and Life Science. Each of theses branches include a number of sub-branches. Physical Science includes areas such as Chemistry and Physics. Earth Science includes areas such as Geology, Meteorology, and Astronomy.
3-The universe is all of space and time and their contents, including planets, stars, galaxies, and all other forms of matter and energy. The Big Bang theory is the prevailing cosmological description of the development of the universe
4-the phenomena of the physical world collectively, including plants, animals, the landscape, and other features and products of the earth, as opposed to humans or human creations.
5-biology is the study of life, more specifically "a branch of knowledge that deals with living organisms and vital processes"; chemistry consists of "a science that deals with the composition, structure and properties of substances and with the transformations that they undergo Physics is the basic physical science. ... Physics can, at base, be defined as the science of matter, motion, and energy. Its laws are typically expressed with economy and precision in the language of mathematics.
