The small intestine comprises of an external layer called epithelium, from which originates microvilli that are the extensions of the small intestine, which projects in the form of tubes and their prime activity is to give a large surface area of absorption to obtain the majority of nutrients.
The nutrients obtained by the microvilli are included into the circulatory system, the prime activity of the circulatory system is to carry different constituents like amino acids, glucose, proteins, and other complex components like oxygen and hormones. It also helps in the conduction of various metabolic wastes discharged from the tissues.
The circulatory system comprises many kinds of capillaries, the most essential of which are arterial capillaries, venous capillaries, and fenestrated capillaries. The fenestrated capillaries are characterized by the pores present in the endothelial cells, which permits small molecules and restricted concentrations of proteins to pass through.
The most essential nutrient carried during the whole process is glucose. It has been considered as the prime source of energy, which is further hydrolyzed to produce two molecules of ATP. The ATP is known as the energy currency of the cell as it provides energy for different cellular and metabolic procedures essential for life.
Answer:
I chose biology to study life. I want to learn more about the life cycle and the way it works. This magor is a import part of my life because it will teach me more about my kind and other like me. it will also give me a better understanding about plants, animals, and humans.
Explanation:
Answer:
uracil, adenine, cytosine
Explanation:
The anticodon of tRNA binds to the triplet codon of mRNA. Adenine of tRNA would pair with uracil of mRNA codon. Uracil of the tRNA anticodon would pair with adenine of the mRNA codon. Similarly, the guanine of the tRNA anticodon binds to the cytosine of the mRNA codon. The codons of mRNA are read from 5' to the 3' direction. And the polarity of the anticodon of tRNA is opposite to that of the mRNA codons. Therefore, if a tRNA anticodon has a sequence of "Adenine, Uracil, Guanine", it would pair with the mRNA codon with a sequence "uracil, adenine, cytosine".
The answer is B !!
In meiosis ; 4 haploid cells are formed with some DNA variations !! This variation is due to crossing over !!
The answer is The chromosomes reach opposite sides of the cell and begin to be incorporated into two new nuclei. This is the answer because in telophase, the chromosomes that are lined up in the middle of the cell are pulled apart and start to form two nuclei for the daughter cells. To help remember this you can think of the "T" in telophase as Two, because the cell has now formed two nuclei for the daughter cells.
Hope this helps!
