Answer the following question given this paragraph: Avian Birds face special challenges when it comes to obtaining nutrition from food. They do not have teeth and so their digestive system, shown in Figure 34.7, must be able to process un-masticated food. Birds have evolved a variety of beak types that reflect the vast variety in their diet, ranging from seeds and insects to fruits and nuts. Because most birds fly, their metabolic rates are high in order to efficiently process food and keep their body weight low. The stomach of birds has two chambers: the proventriculus, where gastric juices are produced to digest the food before it enters the stomach, and the gizzard, where the food is stored, soaked, and mechanically ground. The undigested material forms food pellets that are sometimes regurgitated. Most of the chemical digestion and absorption happens in the intestine and the waste is excreted through the cloaca. Q: In which part of a bird stomach is food stored, soaked and mechanically ground? Choices: - pancreas - digestion - Gall bladder - gizzard A:
(Answer)
gizzard
Ques: Answer the following question given this paragraph: Translation is the second part of the central dogma of molecular biology: RNA Protein . It is the process in which the genetic code in mRNA is read, one codon at a time, to make a protein. Figure below shows how this happens. After mRNA leaves the nucleus, it moves to a ribosome , which consists of rRNA and proteins. The ribosome reads the sequence of codons in mRNA. Molecules of tRNA bring amino acids to the ribosome in the correct sequence. Q: Translation is the second part of the central dogma of what? Choices: - molecular gastronomy - relativity - string theory - molecular biology A:
Ans: molecular biology

Answer the following question given this paragraph: A change in the sequence of bases in DNA or RNA is called a mutation . Does the word mutation make you think of science fiction and bug-eyed monsters? Think again. Everyone has mutations. In fact, most people have dozens or even hundreds of mutations in their DNA. Mutations are essential for evolution to occur. They are the ultimate source of all new genetic material in a species. Although most mutations have no effect on the organisms in which they occur, some mutations are beneficial. Even harmful mutations rarely cause drastic changes in organisms. Q: A change in the sequence of bases in dna or rna is called a what? Choices: - infection - isolation - accumulation - mutation A:
(A).
mutation
Ques:Answer the following question given this paragraph: The energy for photosynthesis comes from light. Without light energy, photosynthesis cannot occur. As you can see in the Figure below , plants can get the energy they need for photosynthesis from either sunlight or artificial light. Q: What is the source of energy for photosynthesis? Choices: - air - gravity - carbon - light A:

Ans:light
