Answer:
C. 1.23 g/ml
Explanation:
[tex] Density = \frac{Mass}{Volume} [/tex]
Mass of rock = 80g
Volume of rock = final fluid volume - initial fluid volume
Volume of rock = 265 cm³ - 200 cm³ = 65 cm³
[tex] Density = \frac{80g}{65 cm^3} [/tex]
[tex] Density = 1.23 g/cm^3 [/tex]
1 cm³ = 1 ml
Therefore, density of the object = 1.23 g/ml

False
Answers
Answer:
true
Explanation:
Density is the only thing affecting whether something floats or sinks. If an object has a higher density than the fluid it is in (fluid can mean liquid or gas), it will sink. If it has a lower density, it will float. Density is determined by an object's mass and volume.
All organisms utilize adenosine triphosphate (ATP) as their major source of energy. The molecules
of ATP and ADP (adenosine diphosphate) + P: (inorganic phosphate) form a cycle to allow for a
constant source of energy-rich ATP molecules.
Which of the following MOST accurately describes the role of ATP as a source of energy?
O ATP absorbs energy as it is converted into ADP + Pi.
ADP + P; release energy as they are converted into ATP.
O When ATP is converted into ADP + Pi , energy is released and used by the cell.
O When ADP + Pi are converted into ATP, energy is released and used by the cell.
Answers
Answer:
When ATP is converted into ADP + P energy is released and used by the cell.
Explanation: ATP contains energy, when a certain part breaks off it converts into ADP and releases energy for the cell tp use.
When ATP is converted into ADP + Pi , energy is released and used by the cell is the most accurately describes the role of ATP as a source of energy.
What is ATP?An organic substance called adenosine triphosphate (ATP) gives energy to a variety of biological functions in living cells, including muscular contraction, nerve impulse transmission, condensate dissolving, and chemical synthesis.
ATP is frequently referred to as the "molecular unit of currency" of intracellular energy transfer and is present in all known forms of life. It either transforms into adenosine monophosphate (AMP) or adenosine diphosphate (ADP) when absorbed in metabolic activities (AMP).
ATP is replenished by other processes. Every day, the human body recycles the equivalent amount of ATP to its own body weight. Additionally, it serves as a coenzyme and a precursor to DNA and RNA.
Therefore, When ATP is converted into ADP + Pi , energy is released and used by the cell is the most accurately describes the role of ATP as a source of energy.

Refer to the family pedigree shown here. In generation I, one parent is affected by the gene mutation and one parent isn't. In generation II, all three children are affected by the gene mutation. What can you conclude about this gene mutation?
Answers
Answer:
What can be concluded about this genetic mutation is that it is inherited as a dominant trait.
Explanation:
In the case that one of the parents has a mutation whose inheritance pattern is dominant —which is rare— all the descendants will have the same mutation, since this gene will necessarily be expressed.
A dominant allele is one whose presence produces the phenotypic expression of the characteristic it determines. When the mutation is dominant, it will always be expressed in the descendants.
Hungtinton's disease and achondroplasia are examples of mutations with an autosomal dominant inheritance pattern.

D). different due to independent assortment during meiosis
Explanation:
Gametes that an organism produces accommodates a blend of genes of that organism and in each gamete, this blend or combination is 'distinct and that is due to independent assortment during meiosis.' It implies that the chromosomes pass randomly for isolation of poles during the division of cells at the time of the process of meiosis and this independent segregation causes each gamete to contain a unique combination of genetic code.

They begin to move the string faster and faster. When they move the string, the energy (remains the same / increases / decreases) and the frequency (decreases / increases / remains the same). Group of answer choices increases, increases remains the same, remains the same decreases, decreases increases, decreases
Answers
energy increases frequency decreases :)
When two boys move the string, the energy increases, and the frequency increases. Thus, the correct option for this question is A.
How are energy and frequency of waves related to one another?The energy and frequency of waves are always directly related to one another. It means that when energy increases, frequency increases. When energy decreases, the frequency decreases.
Now, according to the context of this question, when two boys begin to move the string faster and faster, the energy gradually increases with an increase in frequency as they both are directly related to one another.
Therefore, when two boys move the string, the energy increases, and the frequency increases. Thus, the correct option for this question is A.

Use hydrogen bonding to explain how the unique properties of water you observed emerge.
Answers
Due to the existence of hydrogen bonding between the hydrogen atom and an oxygen atom of a water molecule, it shows the following unique properties.
It is polar in nature.It has a high heat of vaporization and high specific heat.Its solid form is less dense as compared to its liquid form.It illustrates other properties like cohesion and adhesion.It acts as a universal solvent.How the charges are distributed in a water molecule?The distribution of charge is determined by the fact that the oxygen atom attracts electrons a bit more strongly than the hydrogen atom. This is due to the unequal sharing of electrons between the two different atoms.
This unequal sharing of electrons is responsible for obtaining a slight negative charge near the oxygen atom, while a slight positive charge near the hydrogen atom.
Therefore, it is well described above.

Which do scientists link to increased hurricane strength?

B. Higher land temperatures in the arctic
C. Higher ocean temperatures in the tropics
O D. Higher land temperatures in the tropics
Answers
Answer:
Higher ocean temperatures in the tropics
Explanation:
apex :)
Higher ocean temperatures in the tropics are linked to increased hurricane strength. Therefore, option (C) is correct.
What is hurricane strength?Hurricane strength is a measure of the intensity of a tropical cyclone, which is a rotating storm system that forms over warm ocean waters in the tropics. The strength of a hurricane is measured using the Saffir-Simpson Hurricane Wind Scale, which ranks hurricanes from Category 1 (weakest) to Category 5 (strongest) based on their sustained wind speeds.
Hurricanes can cause significant damage due to their strong winds, heavy rainfall, storm surges, and flooding. The strength of a hurricane is influenced by a variety of factors, including warm ocean temperatures, low wind shear, and high humidity. As global temperatures continue to rise due to climate change, it is expected that hurricanes will become more frequent and more intense, which could have significant impacts on coastal communities and infrastructure.
