Answer:
- The building blocks of DNA molecules are amino acids. False
- DNA molecules contain a 5-carbon sugar called deoxyribose. True
- The nitrogen bases found in DNA molecules include adenine, cytosine, guanine, and thymine. True
Explanation:
The building blocks of the deoxyribonucleic acid (DNA) are nucleotides, while amino acids are the building blocks of proteins. Each nucleotide consists of one of four possible nitrogenous bases: two purines (i.e., adenine and guanine) and two pyrimidines (i.e., cytosine and thymine). In DNA, each nucleotide consists of one of these four nitrogenous bases, a five-carbon sugar molecule (called deoxyribose), and a phosphate group. The DNA molecule has a double-helix structure, where nitrogenous bases are inside the double helix while sugars and phosphates are outside. In DNA, cytosine always pairs with guanine and thymine always pairs with adenine.
Answer:
The dependent variable is: the temperature at which liquid boils.
Explanation:
The Dependent variable in a study or research is the variable that is measured after the modification or change in the particular research independent variable.
In this case, the independent variable is the treatment that liquid or water get which is the addition of 3 gm salt, and in the response to this treatment change in the boiling point of the liquid will be the dependent variable.
Thus, the correct answer is - the temperature at which liquid boils.
Answer:
A. Chromosomes make up genes
Explanation:
Step 1
Glucose enters glycolysis pathway and glycolysis yields pyruvate, then pyruvate undergoes processing.
step 2
Pyruvate processing ;releases acetylCOA which joins the citric acid cycle.
Step 3
The citric acid cycle yields 2ATP and CO2 and also releases NADH and FADH2 to electron transport chain and chemiosmosis.
Step 4
Chemiosmosis and electron transport chain yields 25 ATP molecules and H2O Oxygen enters electron transport chain and osmosis.
The primary consumers like rabbits or other small animals that are normally eaten by the secondary consumers (snakes) would over populate and eat all of the producers (plants) and the plants would die out. This would eventually lead to the decrease of the primary consumer (rabbit/small animals) population.
