I’m doing the test right now
Answer:
Student A has a protein receptor capable of detecting a bitter molecule found in that substance, whereas student B lacks that particles protein receptor
Explanation:
The sensory organs helps to respond to the change in the external and internal environment. The five main types of sense organs are eyes, ears, nose, skin and tongue.
Tongue contains different types of taste buds and taste receptors that helps to distinguish between the different types of food. The receptors are mainly responsible for the taste detection. The student B is unable to taste the bitter molecule because they lacks the receptor.
Thus, the correct answer is option (c)
Answer:
D
Explanation:
During metaphase of cell division, the chromosomes line up in the metaphase plate and the spindle fibers from the poles extend and attach to the centromeres of the chromosomes. The spindle then contracts and pull different chromosomes to the opposite poles of the cell before the parent cell divides. If spindle fibers do not form, then the chromosomes will not separate during anaphase.
Therefore, the final cell after mitosis will be a cell with double the number of chromosomes -because if you remember, during interphase, genetic material is replicated so each daughter cell can have its copy-. Due to quality control in the process of cell divisison, this cell will mostly undergo apoptosis, otherwise, it could develop into cancer.
The statement given is the function of RNA.There are three types RNA. Messenger RNA (mRNA) molecules carry the coding sequences for protein synthesis. Rribosomal RNA (rRNA) molecules form the ribosomes, ribosomes are the site of protein synthesis. Transfer RNA (tRNA) molecules carry amino acids and add to the chain of amino acids to form polypeptide chain or protein molecule.
