Based on the description of DNA, given in the Do Now, what could be the nucleotide composition of a DNA double helix? 90 points 20% adenine, 20% guanine, 30% thymine, 30% cytosine 60% adenine, 20% thymine, 10% guanine, 10% cytosine 20% adenine, 20% thymine, 30% guanine, 30% cytosine 60% adenine, 20% guanine, 10% thymine, 10% cytosine
Answer:
20% adenine, 20% thymine, 30% guanine, 30% cytosine
Explanation:
Edwin Chargaff stated in his rule that, in a DNA molecule, the amount of purine bases (Adenine and Guanine) should equate the amount of pyrimidine bases (Cytosine and Thymine). Mathematically, this means that;
A + G + C + T = 100%
Where;
% Adenine base = % Thymine base
% Guanine base = % Cytosine base
Hence, according to this question, the DNA molecule described will contain
20% adenine = 20% thymine,
30% guanine = 30% cytosine
20% A + 20% T + 30% G + 30% C = 100%

Role of Lipids and Carbohydrates - Type Lipid or Carbohydrate behind each question. 16. Provide long term energy storage. 17. Provide insulation and protection. 18. Short term energy supply 19. Composes cellulose in trees and plants. 20. Main component of cell membranes 21. Provide a waterproof coating on leaves and feathers. 22. Composes chitin exoskeleton of insects. 23. Act as chemical messengers in the body.
Answer:
16. Carbohydrates
17. Lipids
18. Carbohydrates
19. Carbohydrates
20. Lipids
21. Lipids
22. Carbohydrates
23. Lipids
Explanation:
Carbohydrates are organic molecules composed of carbon, hydrogen and oxygen. Carbohydrates can be classified into three types: monosaccharides (e.g. glucose), disaccharides (e.g., lactose), and polysaccharides (e.g., starch). Cellulose is a carbohydrate where many glucose rings chain together, while chitin is a polysaccharide consisting of chains of modified glucose molecules.
Lipids represent a diverse group of organic molecules that include, among others, fats, waxes, oils, hormones, etc. Lipids play a role by insulating (and protecting) the body. For example, there is a layer of fats beneath the skin which enables to maintain body temperature relatively constant. In animals, lipids constitute about 50% of the mass of cell membranes. These membrane lipids are mainly phospholipids, glycolipids and cholesterol. There are hormones that derive from lipids such as steroid hormones, which derive from cholesterol. Some examples of steroid hormones are testosterone, estrogen and cortisol.

Compare the data shown in the table. What reasonable conclusion can be made from the information given?
Diffusion is the movement of molecules from an area of high concentration of molecules to an area with a ____ concentration.
A. Equal
B. Higher
C. Lower
D. None of the above
Answer:
lower
Explanation:
Diffusion is the movement of molecules from an area of high concentration to an area of lower concentration. So, the correct option is C.
What is diffusion?Diffusion is a type of passive transport, this means that it does not require any kind of external energy for movement of molecules. The difference in concentration in two areas gives rise to a concentration gradient. Where, in one area there is high concentration of molecules and in another, there is low concentration of molecules.
If the molecules move from an area of higher concentration to an area of lower concentration, they are moving along the direction of concentration gradient. This is why no additional energy is required. Diffusion is a type of passive transport where molecules move along a concentration gradient.
This is in contrast to active transport where molecules move against the concentration gradient and therefore require external energy.
Therefore the correct option is C.

How does water behave when it freezes?
Answer:
During freezing, water molecules lose energy and do not vibrate or move around as vigorously. This allows more stable hydrogen-bonds to form between water molecules, as there is less energy to break the bonds...Thus water expands as it freezes, and ice floats atop water.
