A water molecule contains two hydrogen atoms and one oxygen atom. Which of the following
statements about water molecules is true?
A. All of the atoms have a positive charge.
B. All of the atoms have a negative charge.
C. The oxygen atom is positively charged and the hydrogen atoms are negatively charged.
D. The oxygen atom is negatively charged and the hydrogen atoms are positively charged.
Answer:
D. The oxygen atom is negatively charged and the hydrogen atoms are positively charged.
Explanation:
A water molecule is consists of two hydrogen bonds and one oxygen bond. The hydrogen and oxygen atoms share unequal electrons to form covalent bonds.
Due to unequal sharing of electrons oxygen atoms attracts electrons more strongly than the hydrogen atoms and oxygen gains a slightly negative charge and hydrogen atom gains slightly positive charge.
Hence, the correct option is "D. The oxygen atom is negatively charged and the hydrogen atoms are positively charged."
Help please ! Thanks
Answer:
75%
Explanation:
The allele for purple flowers (capital P) is dominant.
The allele for white flowers (lowercase p) is recessive.
If one allele is capital P, it doesn’t matter if the other allele is another capital P or a lower case p, the capital P will dominate and purple flowers will show up.
The Punnett Square shows:
PP, Pp, Pp, and pp
• 3 of the offspring have at least one dominant and capital P, so purple flowers show up.
• 1 of the offspring has two lowercase and recessive alleles (p), so white flowers show up.
3/4 or 75% of the offspring will have purple flowers.
[tex]\huge\boxed{Option A}[/tex]
_____________________________________ PEA PLANT:Pea plant has purple color flowers dominant over white color flowers.
Purple flower dominant allele is P
White Flower recessive allele is p
We would get White flower pea plant only when the recessive allele is in HOMO.ZYGOUS condition
_________________________________________________________
CONDITIONS:Hom.ozygous Dominant Alleles: PP (Purple Flower)
Heter.ozygous Dominant Alleles: Pp Purple Flower)
Hom.ozygous Recessive Alleles: pp (White Flower)
____________________________________ CROSS:Whenever we cross Heterozygous Dominant(Pp) purple flower with another Heterozygous dominant (Pp purple flower), we get 75% of the flowers PHENOTIPICALLY(physical appearance) white flowered, and 25 white flowered Because as you can see in the picture,
The P1 is Pp
The P2 is Pp
When we cross them,
It has 4 offsprings,
PP Hom.ozygous Purple flower
Pp Heterozygous Purple flower
Pp Heterozygous Purple flower
pp Hom.ozygous white flower
Thus the answer is 75% as there are phynotypically 3 purple flowers present

When comparing mitochondria and chloroplasts in plant cells, which statement BEST explains a similarity in the cellular function of these organelles
A
These organelles are both important for the uptake of nutrients from the cell's exterior.
B
These organelles are both important in the regulated transport of molecules within cells.
с
These organelles are both important for the conversion of energy to a usable form for cells.
D These organelles are both important for the use of cellular genetic information to make proteins.
Answer:
The correct answer is - с. These organelles are both important for the conversion of energy to a usable form for cells.
Explanation:
Chloroplast and mitochondria are the two organelles that are essential for the biosphere specially autotrophs like plants and heterotrophs as chloroplast is the organelle that converts light energy into chemical energy by forming sugars by the process called photosynthesis by trapping the sunlight.
This chemical energy that is stored in glucose molecule moves to the mitochondria where by the procee of the cellular respiration the chemical energy converted to the ATP, the energy form that is used by the cell for the performing its function.

The answer would be E.
Explanation:
Ive attached a transcription chart that is easier to follow and use than the one you posted.
Remember that uracil is used in rna instead of Thymine so you will change any letter Ts in DNA to U.
What is the phenotype(s) you can expect from crossing a pure round parent and a
pure wrinkled parent?
R=round
r=wrinkled
Answer:
Round
Explanation:
Round is the dominant phenotype and wrinkled is the recessive one. When crossing, the offspring will have one allele from each parent, i.e. Rr, wrinkled phenotype will hence be masked by the dominant round one.

how efficient both lungs and gills are in these crabs?
Answer:
In crabs, gills are more inferior to lungs in O2 uptake, but they are both quite efficient.
Explanation:
Hope this helped!
Answer:
Both are used for oxygen intake and excretion
Explanation:
In all species, the lungs were extremely effective in oxygen uptake whilst the performance of the gills was inferior. An exception to this was Gecarcoidea natalis, which has gills highly modified for aerial gas exchange; its gills and lungs were equally efficient in O2 uptake. The relative efficiencies of the lungs and gills in CO2 excretion differed between species, with the gills being the major site of CO2 loss in the more amphibious species and the lungs having an increasingly important role in the more terrestrial crabs. The presence or absence of lung portal systems was not found to correlate with either saturation rates or efferent oxygen concentrations, with both lung types being extremely efficient in O2 uptake. The lungs with portal systems showed a large increase in oxygen content in the first lacunar bed and progressively smaller increases in the next two; these lungs may, therefore, have some reserve for exercise.
How are dewpoint and relative humidity related?
Answer:
Explanation:
Dew point is the temperature to which air must be cooled to become saturated with water vapor. Relative humidity is the percent of saturation at a given temperature; it depends on moisture content and temperature. Relative humidity is the amount of moisture actually in the air to the maximum amount that can be present at that temperature. The dew point is the temperature at which a given sample of air will have a relative humidity of 100 percent; hence, the saturation temperature.

Which of the following is a nucleotide found in DNA?
F
adenine + phosphate group + thymine
G
cytosine + phosphate group + guanine
H
deoxyribose + phosphate group + polymerase
J
deoxyribose + phosphate group + cytosin
Answer:
H
Explanation:
Answer:
J
Explanation
A nucleotide consists of a sugar molecule (in this case, deoxyribose), a phosphate group and a nitrogenous group. Based on this definition of a nucleotide, J would be the most appropriate answer as it lists deoxyribose (sugar molecule), a phosphate group and the nitrogenous base cytosine.
