How is the atomic mass found?
Answer:
The average atomic mass for an element is calculated by summing the masses of the element's isotopes, each multiplied by its natural abundance on Earth. When doing any mass calculations involving elements or compounds, always use average atomic mass, which can be found on the periodic table.1) The property of matter that describes a solvent is mixing with a
solute to make a solution is known as

White blood cells are especially active when you are sick because their primary job is to fight off infections – often bacteria or viruses that do not belong in you. Once they locate the invader making you sick, they eat it and destroy it. What organelle do you think is plentiful in white blood cells?
Answer:
Lysosomes
Explanation:
Lysosomes are membrane bound organelles that contain degradative enzymes. They degrade worn-out cellular parts and may also be used by cells to degrade/destroy invading bacteria or viruses. Hence, since white blood cells are primarily responsible for fighting infections, it is expected that they have a high amount of lysosomes (which they indeed do have in high amount).

Question:
The complete question has these options:
A) tRNA with anticodons is carrying amino acids to the ribosomes.
B) DNA polymerase is using both strands of DNA to produce multiple RNA molecules.
C) Ribosomes are reading mRNA molecules three nucleotides at a time to synthesis proteins
D) RNA polymerase is using a single strand of the DNA molecule as a template for mRNA production
Answer:
D) RNA polymerase is using a single strand of the DNA molecule as a template for mRNA production
Explanation:
During transcription, RNA polymerase uses DNA as a template to create a new molecule of mRNA via complementary base pairing
A) tRNA with anticodons is carrying amino acids to the ribosomes. - this is not evidence of transcription but is instead evidence of translation
B) DNA polymerase is using both strands of DNA to produce multiple RNA molecules. - this is false, DNA polymerase is the enzyme that performs DNA replication not transcription.
C) Ribosomes are reading mRNA molecules three nucleotides at a time to synthesis proteins - this is not evidence of transcription but is instead evidence of translation
D) RNA polymerase is using a single strand of the DNA molecule as a template for mRNA production - this accurately describes the process of transcription.
Which of the following represent an ecosystem?
A: A lake
B: a fish tank
C: a prairie
D: All of these
Answer:
D
Explanation:
all of them are ecosystems:
Lakes/Ponds are a prime example of lentic ecosystems
Fishtanks are are described as a closed artifical ecosystems
Prairies are unique ecosystems that are dominited by grass and other plants.
Answer:
the total amount of matter
Explanation:
In a closed system, the total amount of matter remains the same as it is transferred between organisms and the physical environment, even though its location or form changes.
When one organism consumes another, this matter can change form, but it does not disappear. Eventually, the matter is broken down by decomposers and deposited in the ecosystem's soil, where it can be used by plants. From there, it is able to begin the cycle all over again.

Heredity is the passage of genetic instructions from parent to offspring. The genetic instructions are found in within the DNA, which is contained in inside the nucleus of the cells. The genetic information is passed to the next by sexual reproduction. The information controls the traits that passed down. These include characteristics like eye color and characteristics like blood type. These traits are directly passed down and are not affected by the surrounding the organism.
Answer:
What is your question
Explanation:
The passage of genetic instructions from parent to offspring, known as heredity, involves the transmission of genetic information contained within the DNA.
The DNA is primarily located within the nucleus of cells. During sexual reproduction, genetic material from both parents combines to form a unique set of instructions for the offspring.
This genetic information controls the traits that are inherited, including observable characteristics like eye color and blood type. These traits are directly inherited and are not influenced by the surrounding environment of the organism.
While genetic information provides a blueprint for traits, the expression of those traits can be influenced by environmental factors, such as nutrition, exposure to toxins, or lifestyle choices.

in what ways is ATP like a fully charged battery?
Answer:
ATP ATP can be compared to a fully charged battery because both contain stored energy, whereas ADP resembles a partially charged battery. Releasing Energy From ATP The energy stored in ATP is released when ATP is converted into ADP and a phosphate group.
Explanation:
The ATP molecule is comparable to a battery that can be recharged. It is ATP when ultimately charged. It's ADP when it's worn out. When the battery runs out, it is simply recharged rather than discarded.
What is ATP?A vital "energy molecule" in all living things is adenosine 5′-triphosphate, also known as ATP and typically written without the 5′-. In particular, it is a coenzyme that transfers cells' energy by liberating its phosphate groups when it interacts with enzymes like ATP triphosphatase. The molecule comprises an adenine bicyclic system, a furanose ring, and a triphosphate chain.
The discovery of ATP was announced in 1929 by two research teams. It was isolated from mammalian muscle and liver by Cyrus H. Fiske and Yellapragada Subbarow at Harvard Medical School (Boston). Karl Lohmann discovered it in muscle tissues while working for the Kaiser Wilhelm Institutes in Berlin and Heidelberg.
Over the next 15 years, ATP separation from other sources came next. In 1987, Koscak Maruyama of Chiba University (Japan) provided a thorough analysis of ATP's discovery and structural elucidation.
Therefore, ATP is like a rechargeable battery because it can be recharged and discharged.

Imagine a science fiction movie in which a scientist creates a new species of organism. The scientist generates a whole population of the organism entirely through cloning of the males and females and then leaves them on an island. Explain why the population of clones would struggle to evolve if there was a major environmental change on the island.
The population of clones that struggle to evolve if there was a major environmental change on the island is :
-Lack of variations in the population as the clones are products of without fusion reproduction.
"Environmental change"The population of clones will struggle due to lack of variations in the population as the clones are products of without fusion reproduction.
Without fusion reproduction will allow the parent organism to produce offspring that are exactly identical to the parent.
Also it will help in production of large number of progenies at a single time.
Therefore, the population of clones will struggle due to lack of variations in the population as the clones are products of without fusion reproduction.
