What is attracted to the oxygen atom in a water molecule?
a. A partially positive hydrogen atom in a second water molecule
b. A partially negative hydrogen atom in a second water molecule
c. A positive ion, such as Na+
d. Both a and c
Answer:
a.
Explanation:
The slight positive charges on the hydrogen atoms in a water molecule attract the slight negative charges on the oxygen atoms of other water molecules. This tiny force of attraction is called a hydrogen bond.

Hydrogen peroxide is a substance that is produced as a byproduct of many cell processes. However, hydrogen peroxide is toxic to cells. In fact, if cells are unable to break down hydrogen peroxide, they become poisoned and die.
The chemical reaction for the breakdown of hydrogen peroxide is shown below.
What role does catalase play in this reaction?
Answer:
In the reaction of decomposition of hydrogen peroxide (H₂O₂), catalase is the enzyme responsible for catalyzing this reaction.
Explanation:
Catalase is an oxide-reductase enzyme whose substrate is H₂O₂, a potentially harmful by-product of metabolism.
The reaction that is mediated by catalase is:
H₂O₂ ------catalase--- → 2H₂O + O₂
where catalase is the enzyme that breaks the bond of the additional oxygen in the molecule to obtain H₂O and free O₂.
People with catalase deficiency may experience disorders and diseases due to the accumulation of H₂O₂ in the body.
State two uses of fats to living organisms
Answer:
they act as messengers, helping proteins and do their job
The two uses of fats in living organisms are as follows:
They are actively involved in the storage of energy for metabolic functions. Fats generally insulate us and protect our vital organs.What are Fats?Fats may be characterized as a type of naturally occurring chemical substance that significantly describes a class of macronutrients utilized in metabolism called triglycerides.
Fat usually means any ester of fatty acids, or a mixture of such compounds, most commonly those that occur in living organisms. These groups of macronutrients are generally involved in the storage of energy for metabolic functions.
Triglycerides, cholesterol, and other essential fatty acids are the scientific term for fats the body can't make on its own in order to store energy, insulate us and protect our vital organs. They act as messengers, helping proteins do their jobs.

What does it mean to have a hypotonic solution?
Answer:
A hypotonic solution has a lower concentration of solutes than another solution. In biology, a solution outside of a cell is called hypotonic if it has a lower concentration of solutes relative to the cytosol. Due to osmotic pressure, water diffuses into the cell, and the cell often appears turgid, or bloated.
Answer:
alright so there's 3 kinds of solutions!
hypotonic, isotonic and hypertonic
basically a cell is in a hypotonic
solution if the concentration of water
inside the cell is LOWER than the concentration
outside the cell. Water diffuses from high
to low. Water enters the cell.
and this is talking about ions!

Which describes sexual reproduction, and not asexual reproduction?
Answer:
One characteristic that describes sexual reproduction and that is not present in asexual reproduction is the combination of genetic information from two parents.
Explanation:
Sexual reproduction involves the participation of two individuals, whose genetic material is contributed and when they unite they give birth to a new individual, through the process of fertilization.
Individuals who reproduce sexually have the ability to form cells with half of their genetic charge, called gametes. The union of these cells forms the zygote, from which a new individual develops.
In asexual reproduction, a single individual is responsible for the reproductive process, which occurs by
Gemination. Bipartition Fragmentation. Parthenogenesis. Sporulation or sporogenesis.Each one of these processes represents a different type of reproduction than the one that occurs sexually.

Having straight ears (E) is dominant over droopy ears (e). A parent with straight ears is crossed with a parent with droopy ears. The Punnett square will show the possible genotypes of the offspring. What is the genotype of each square?
A: EE, Ee, ee
B: EE, Ee, ee
C: EE, Ee, ee
D: EE, Ee, ee
Answer:
Ee Ee ee ee 50/50 on having either droopy ears or straight
Explanation:
The genotype of square A is Ee, square B is ee, square C is Ee, and square D is ee.
What are genotypes?Genotypes are the genetic makeup or the complete set of genes that an individual organism possesses. They are responsible for determining an organism's physical and behavioral traits.
The genotype of an organism is encoded in its DNA, which consists of long sequences of nucleotides that code for specific proteins and other functional molecules. These nucleotide sequences are organized into genes, which are located on chromosomes in the nucleus of the cell.
Genotypes can be inherited from parents and passed down to offspring through sexual reproduction. However, mutations and genetic variations can also occur spontaneously, leading to changes in an individual's genotype.

Ms. Hendren has decided that she would like to grow some tomatoes and wants to know how much light will cause the plant to grow the largest tomatoes. She plants tomato seeds in 4 different pots and leaves one pot in the dark. She gives 6 hours of light a day to the second, 8 hours of light a day to the third, and 10 hours of light a day to the fourth. After 3 months she measures the size of the tomatoes grown. Match up each variable in the experiment. Group of answer choices Independent varible [ Choose ] Dependent variable [ Choose ] Control variable [ Choose ] Control group [ Choose ]
Answer:
The correct answer is -
Independent variable - the amount (time period) of light given to pots.
Dependent variable - size of tomatoes
Control variable - dark or absence of light
Control group - pot placed in the darkroom.
Explanation:
The independent variable is the variable that is changed or manipulated in particular research or study to see the effect of that variable on dependent variable. In this case, the amount of light each pot gets is the independent variable.
The dependent variable is the variable that depends on the change in the independent variable. The size of tomatoes is the dependent variable here.
The control variable is the variable that remains in standard condition or condition which can be used to compare with the effect of the independent variable. The absence of light on one of the tomato pot is the control variable.
The control group is the group of subjects did not get any treatment that experiment group receives. The pot which is placed in the dark room is control group here.

They are not based on scientific evidence, and earthquakes are part of a scientific process. For example, earthquakes have nothing to do with clouds, bodily aches and pains, or slugs.
If you wanted to stay 20 feet below the surface of the water, what kind of buoyancy would you need to have? Positive, Negative or Neutral?
Answer:
It depends what kind of water.
Explanation:
Salt water:
You would need a negative buoyancy.
Fresh water:
You would need a neutral buoyancy.
Please let me know if I am wrong!
Buoyancy is the tendency of an object to float at the upper surface of the fluid due to upwards force. If the diver wants to stay below the water surface then they will need negative buoyancy.
What is buoyancy?Buoyancy has been defined by the upthrust experienced by an object in a fluid or liquid medium. It is a force that opposes or counters the weight of the object. Buoyancy can be positive, neutral, or negative. Positive buoyancy makes object float.
A negative buoyancy occurs when the object has more mass and density than the fluid so that the applied force makes them sink. So, if a person wants to stay 20 feet below the surface of the water then negative buoyancy has to take place.
Therefore, negative buoyancy will make a person stay at the bottom of the water.

Through photosynthesis certain energy’s convert solar energy into chemical energy. Photosynthesis is the process used by plants to harness energy from sunlight. It is an endothermic (takes in heat) chemical process that uses sunlight to turn carbon dioxide into sugars. The sugars are used by the cell as energy, and to build other kinds of molecules.
