Due to the partial charges on atoms in a water molecule, ____ in water molecules are attracted to oxygen atoms in other water molecules.
Hydrogen bond in water molecules are attracted to oxygen atoms in other water molecules.
A hydrogen bond is a strong dipole-dipole attraction which occurs between:
the hydrogen atom attached to a strongly electronegative atom (for example oxygen in water molecules)another strongly electronegative atom with a lone pair of electronsHydrogen bonding occurs in the following compounds which include water, hydrogen fluoride and ammonia.
When an electronegative atom such as oxygen is bonded to hydrogen, a dipole develops causing the hydrogen to be partially positive while the other atom is partially negative.
Thus, this accounts for high boiling point in compounds that contains hydrogen bonds.

A) 1 g/cm3 (gram per cubic cm)
B) 2 g/cm3
C) 3 g/cm3
D) 4 g/cm3
E) 5 g/cm3
Answer:
C) 3 g/cm3
Explanation:
Density=mass/volume
D=12/4
Cancel out with the common factor 4
D=3 g/cm3
Therefore density is 3 g/cm3
Explain the relationship between urea cycle and citric acid cycle?
Answer:
one of its nitrogens through transamination of oxalacetate to form asparate and returns fumarate to that cycle.
Explanation:
The urea cycle is linked to the citric acid cycle by fumarate and by aspartate, which can be con- verted to malate by transamination (see Figure 23.22). ... Aspartate and arginosuccinate are the amino acids that link the two pathways. Aspartate is made by transamination of OxaloacetatA.

The purpose of an experiment is to gather data to determine if the Is supported or not supported
Answer:
hypothesis
Explanation:
the reason you do the experiment is to test the hypothesis
The purpose of an experiment is to systematically gather data and information through controlled procedures in order to investigate a hypothesis or research question. The goal is to determine whether the hypothesis is supported by the collected evidence or not.
Here's a breakdown of the process:
1. **Hypothesis:** An experiment starts with a clear hypothesis or research question. This is a statement that suggests a relationship or an effect between variables.
2. **Design:** The experiment is designed with careful consideration of variables, controls, and methods. Variables are factors that can change or influence the outcome. Controls are used to minimize the impact of extraneous variables that could affect the results.
3. **Data Collection:** During the experiment, data is collected by making observations, measurements, or recordings of relevant variables. This data is collected according to the experimental design.
4. **Analysis:** Once the data is collected, it is analyzed using statistical or other relevant methods. The analysis aims to uncover patterns, relationships, and trends in the data.
5. **Interpretation:** Based on the analysis, researchers interpret the results to determine whether the collected data supports or contradicts the initial hypothesis. The interpretation should be objective and based on evidence.
6. **Conclusion:** The conclusion drawn from the experiment is either that the hypothesis is supported (the data aligns with the predicted outcome) or not supported (the data does not align with the predicted outcome).
7. **Implications:** If the hypothesis is supported, it can lead to further understanding, validation, or application of a concept. If the hypothesis is not supported, it could suggest a need for revising the hypothesis, altering the experimental design, or exploring different avenues of research.
It's important to note that a single experiment might not definitively prove or disprove a hypothesis. Replication of the experiment by other researchers and conducting further studies can provide more robust and reliable conclusions. In summary, the purpose of an experiment is to generate data that enables researchers to draw conclusions about whether a hypothesis is supported or not supported by the observed evidence.

Answer:

Your lab team mixes dry baker’s yeast with warm water and divides the mixture between two test tubes. You add 5 grams of sugar to one test tube but nothing to the other tube. A small balloon is placed over the mouth of each test tube. After 30 minutes your team records the following observations.
Yeast and warm water: The water is cloudy after a minute. After 30 minutes the yeast is settled to bottom of tube, water is less cloudy.
Yeast, warm water and sugar: The water is cloudy, a few bubbles have formed on top of the water. After 30 minutes the water is cloudy, lots of bubbles in the test tube, balloon has inflated some.
What is the BEST inference you could make about the yeast based on the data?
(4 Points)
The yeast needs warm water to grow.
The yeast bubbles when it contacts sugar.
Yeast is a living organism that uses sugar for energy.
Yeast is not a living organism because it did not change when added to water.
Answer:
The yeasts are the eukaryotic, microscopic, unicellular organisms belonging to the kingdom fungi. Yeasts are widely used to prepare beer and wine. Yeasts break down the glucose and release ethanol and carbon dioxide. The best interference is yeasts bubbles when it contacts with sugar.
Explanation:
Yeasts are organisms, which can respire aerobically or anaerobically. During the experiment, when yeasts are placed in a test tube with sugar, it starts to grow. The warm water in the test tube ensures the rapid growth of yeast. Sugar is the source of energy that is required by the yeasts to grow. Thus, during the multiplication of the yeast, they utilize oxygen and food to yield carbon dioxide. The gas is evolved and can be tested by the inflated balloon placed over the test tube. The yeasts bubbles out when it comes in contact with the sugar. Thus, to perform any experiment on living organisms, the population of those organisms should be in large quantity. this can be achieved by providing the sources of energy.

Which of the following represents the impacts of drilling and fracking on human health?
I. Heavy metal exposure can cause nervous system damage.
II. Air pollution can aggravate respiratory conditions.
III. Noise pollution can cause headaches, changes in sleep patterns, and anxiety.
- III only
- I and II
- II and III
- I, II, and III
Answer:
II and III
Explanation:
I only applies to mining and not drilling.
The correct answer as to the impacts of drilling and fracking on human health includes nervous system damage as a result of heavy metal exposure, respiratory diseases as a result of air pollution, and headaches, changes to sleep patterns, etc. as a result of noise pollution. The correct answer would therefore be I, II, and III.
Drilling and fracking are innovative technology methods used in the location of water, minerals, and the extraction of crude oil from underground respectively. The methods are characterized by the noise of the drilling machine, air pollution by dust particles as a result of soil excavation, and heavy metal pollution of the environment.The different pollutions have varying degrees of effects on the health of human and these include damages to the nervous system by heavy metal, damages to the respiratory organs as a result of inhalation of particulate matters and headaches/anxiety as a result of noise pollution.Hence, all the three effects represent the impact of drilling and fracking on human health.

If a fruit fly develops legs on its head instead of antenna, what is the most likely reason?
O Chromosomal non-disjunction resulting in extra sets of genes
O Conjugation errors during reproduction
O Frameshift mutation during transcription of mRNA
O Mutation affecting gene expression
Mutation affecting gene expression is the most likely reason for a fruit fly to develop legs on its head instead of antenna.
WHAT IS MUTATION:
Mutation is the process whereby an alteration or change occurs to the sequence of DNA either by mistake during replication or caused by mutagens.WHAT IS GENE EXPRESSION?
Gene expression is the process by which the information encoded by genes are used to synthesize products such as proteins etc. In the organism described in this question, the fruit fly develops legs on its head instead of antenna, it's most likely because the genes encoding the information for the synthesis of antennas on its head have been CHANGED OR MUTATED, hence, causing something else to be formed there.Therefore, mutations affecting gene expression can cause legs to be formed on the head of fruit fly instead of antenna.
