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.

1) The property of matter that describes a solvent is mixing with a
solute to make a solution is known as
A. Contraction
B. Density
C. Solubility
D. Energy
Help!!
Answer:
C. Solubility
Explanation:
Solubility of a substance refers to the ability of a substance called the SOLUTE to dissolve in another substance called the SOLVENT to form a SOLUTION. Matter, which constitutes the solid, liquid and gaseous state, can be the solute, which will get dissolved in the SOLVENT (usually a liquid).
Therefore, according to this question, the property of matter that describes a solvent is mixing with a solute to make a solution is known as its SOLUBILITY
1) Why is embryonic stem cell research controversial?
2) What is a potential source of stem cells that is not controversial?
Answer:
1.) It is controversial because in order to take embryonic stem cells, the embryo must die. This is killing a baby.
2.) Stem cells can be taken from your own body from your blood stem cells. This kind of transplant would be considered an autologous stem cell transplant and could help heal diseased or damaged bone tissue.

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.When protists and fungi are compared, which feature is unique to protists?

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.

how do plant cells differ from animal cells structurally?
Answer:
plant cells have a rigid cell wall that helps it keep shape and animal cells don't
Answer:
Plant cells contain a cell wall to help give better structure and protection than animal cells. Plant cells also contain a large central vacuole that is used to store waste and water. Another thing is that plant cells have an organelle that preforms photosynthesis.

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.

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.

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.
