The properties of water are the result of multiple factors including; polarity and hydrogen bonding. Which property of water is not a result of polarity?
A.Water dissolves salts and sugars.
B.Water will become less dense when frozen.
C.Water is transparent and lets sunlight pass through.
D.Water will from a spherical bead due to surface tension
Answers
Water is transparent and lets sunlight pass through. Therefore, the correct option is C.
Water's transparency and ability to pass through sunlight is not just a product of its polarity. This is mainly because water absorbs only specific wavelengths of light, particularly those in the visible spectrum, while allowing other wavelengths to pass through. Rather than being a direct result of polarity, this property is related to the electrical structure of water molecules and their interactions with light. On the other hand, the interplay of water polarity and hydrogen bonding is the reason for the A, B and D properties, respectively.
Therefore, the correct option is C.

why is the concentration of oxygen in the body cells lower than the concentration of oxygen in the alveolus?
A. Alveolus can produce oxygen.
B. The exchange of gases occur in the alveolus.
C. Oxygen is used up for respiration I the body cells.
S. Oxygen diffuses out from the body cells.
Answers
Answer:
i think the answer should be b.
the alveolus is the site of exchange of gases (carbon dioxide and oxygen) between the body cells and the alveolar air. diffusion requires a concentration gradient, which basically means that there has to be a difference in concentration of the substance (in this case it's oxygen) between the 2 areas (in this case it's the body cells and the alveolar air) hence, there is more oxygen in the alveolar air than the body cells (this difference in concentration is what allows diffusion of oxygen from a region of HIGHER to LOWER concentration!) this allows oxygen to diffuse from alveolus to body cells, giving your body the oxygen it needs!
btw keep in mind that i am by no means an expert in biology (because im still a student), but b is the most logical answer to me. good luck!

They are the fastest growing weed that allowed the plant to build huge populations in its ranges of introduction. They develop dense mats on the surface of the water and becoming a major weed problem.
due to their dense layering in the surface the sun light cant travel properly in the water and the consumption of oxygen is also taken up by them hence it result the lack of oxygen in the water.

what does the author mean when she describes easter island as ""a destination with solitude built into its dna""?
Answers
A destiny with loneliness built into its DNA why, the DNA of the peoples of Easter Island is unique, there is a theory that suggests that long before Europeans discovered the island (in 1722), it served as a meeting place for the Polynesian people and Native Americans. Thus, the Rapa Nui would have in their DNA a mixture of these peoples. That theory was driven by an article published in 2014 that showed that today's Rapa Nui have 8% Native American DNA in their genome.
The why of solitary DNA
The Rapanui, who populated Easter Island,
Had no contact with the Native Americans until the arrival of the Europeans. Or if they did, it left no trace in their genes. That's what a study that analyzed ancient DNA of the island's inhabitants claims.These results call into question previous research that claims that there was contact and that it may have occurred several centuries earlier.
This is the first time Rapa Nui's ancestral DNA has been sequenced. It's the result? None of the five samples showed DNA from Native American ancestors.

Stem cells can be developed into a required tissue because of their ability of cellular DIFFERENTIATION. These cells can develop specialized cells.
Stem cells are cells that can develop into specialized types of cells in order to perform specific functions.
The process of cellular differentiation from stem cells involves differential gene expression patterns, a cellular process that leads to the development of distinct types of cells.
For example, hematopoietic stem cells express specific genes (e.g., the hemoglobin gene) in order to differentiate into mature red blood cells that function to trasnport oxygen to all body cells.

what essential chemicals do the light dependent reactions obtain from the light independent reactions
Answers
Explanation:
Light Reactions: Light-dependent reactions harness energy from the sun to produce chemical bonds, ATP, and NADPH. These energy-carrying molecules are made in the stroma where the Calvin cycle takes place.
The energy storage molecule ATP and the reduced electron carrier NADPH are produced by the light-dependent processes using light energy, which is required for the subsequent stage of photosynthesis.
What are the products of the light-independent reactions check all that apply?
In order to make ATP and NADPH, the light-dependent processes of photosynthesis must first collect energy from the sun.Then, these two molecules that store energy are employed in the light-independent reactions. Two different types of energy-carrier molecules, ATP and NADPH, store the solar energy in the light-dependent reactions.These molecules' stored energy is contained in the bond that binds one atom to the molecule.It is a phosphate atom for ATP and a hydrogen atom for NADPH. The cell has the material it needs to create carbohydrate molecules once the energy from the sun is processed and packed into ATP and NADPH.Carbon atoms will form the backbone of the carbohydrate molecules created. The protein ferredoxin receives electrons from the pigment P700 in its reaction center. Ferredoxin can then donate the electrons to either the electron transport chain to produce more ATP or to the electron carrier NADP+ to make NADPH. The pigment chlorophyll in the thylakoid membranes of the chloroplast is able to absorb solar energy during these reactions.The second stage of photosynthesis uses the molecules ATP and NADPH, which are temporarily transferred the energy to. Chlorophyll absorbs solar energy during the light-dependent reactions and transforms it into chemical energy that is then stored.The chemical energy obtained during the light-dependent reactions powers the construction of sugar molecules from carbon dioxide in the light-independent reactions. Plants require three elements for photosynthesis: carbon dioxide, water, and sunshine. The reactions that depend on light include those that use it to split water, create ATP, and NADPH.The processes that use ATP and NADPH to repair carbon dioxide in order to produce the three-carbon sugar glyceraldehyde 3 phosphate are known as light independent reactions. NADP, ADP, and water molecule reactants are used in the light reaction.After the light processes are finished, the molecules ATP, NADPH, and oxygen are produced, the last of which is already regarded as a byproduct of photosynthesis.To learn more about independent reactions refer

Answer: B Fatty-acid tail
Explanation:
I have attached an image of what the cell membrane looks like, there's something called a phospholipid which makes up the membrane of the cell and as you can see, the head of the phospholipid is faced outwards while the hydrophobic tail is safe on the inside. The inside and outside of the cell has a lot of liquid and water so the hydrophobic (water fearing) part of the phospholipid (the tail) had to be protected and facing inwards away from it!
