Answer: The nitrogen bases that exist on every DNA sample are adenine, thymine, cytosine and guanine, or A, T, C and G, respectively. The same bases are, therefore, present in all three individuals. They aren't presented in the same order, being this the fact that tells plants, mammals and bacterium apart. The structure is always the same, but the sequence is what makes every individual different from each other.
Answer:
No atoms are created or destroyed in chemical reactions.
Explanation:
Matter cannot be created or destroyed. When two reactants contact each other, a chemical reaction occurs which breaks the bonds between atoms and rearranges them, forming new bonds which transform them into the product. The same amount of atoms exists before and after the reaction.
Urea (CH4N2O), bi carbonate ion (HCO-3), creatinine, bilirubin are the ammonia containing products, are eliminated by kidneys through urine by a process of transamination.
Breakdown of amino acids results in formation of ammonium ions.
The elimination or excretion of urea is called ureotelism.
Answer:
The Easter Island once used to be extremely diverse in biodiversity. It had abundant amount of plant and animal species living there.
Biodiversity in the past was extremely high due to favorable conditions there. The temperature and climate of Island was favorable for the growth of plants and animals.
It has mild climate with fertile soil which favored growth but now the scenario is different as it is now barren land with lots of sand and no diversity among plants and animal species is found there.
Answer:
The correct answer is - option A. The smaller your nasal passage, the less force the pressure from your lungs will exert on the clog
Explanation:
Velocity depends on the area of the passage and directly affected by this as velocity is inversely proportional to the area of the passage, therefore, the lesser the nasal passage area higher will be the velocity.
v=Q/A
By this it is clear that the required pressure will be less and velocity will be more and less pressure generated from the lungs.
The correct answer is - option A.
