Answer:
Since albinism is an autosomal recessive trait, it means that both parents must possess the gene for it, for the albinism to occur.
Thus, David could be the father if both Rose and David are carriers(heterozygotes) for the albino allele.
Answer:
The absorbance of 460nm light by the treatment solutions was the test performed by the student.
Explanation:
Cell membranes are phospholipid bilayers which are mostly displayed by the 'fluid mosaic model' which consists of proteins, carbohydrate polymers and glycoproteins making them able to move around quite freely amongst the phospholipids. A normal membrane permeability test involves investigating the effects of a named variable on the membrane permeability of any vegetable such as beetroot whose biological name is Beta Vulgaris. The variables to investigate are the influence of solvents and temperature because these factors can change the fluidity of the membrane. Beetroot is an important item for this test because of the distinctive betalains pigment that its stem tuber contains. These pigments form an important signal indicating membrane fluidity as they are usually contained in the vacuole of intact beetroot cells. An instant or constant increase in membrane fluidity will cause the pigment to spill out of the cell, and the amount of pigment can be measured simply by using a colorimeter.
The above description is performed under the test of The absorbance of 460nm light by the treatment solutions.
Answer:
Error: The Methionine at the end of the chain
Explanation:
Hello! Let's solve this!
The start codon is AUG, this codon encodes Methionine. Therefore all proteins will start the amino acid sequence with Methionine.
In this case, the student placed the Methionine at the end of the chain, so that is the mistake. Methionine goes to the beginning of the chain.
Answer:
1. Reducing
2. External
Explanation:
The external urinary sphincter, also called as external urethral sphincter consists of skeletal muscles. During micturition reflex, the micturition center present in the brain serves to inhibit the somatic motor neurons by reducing their action potential. These somatic motor neurons innervate in the external urinary sphincter.
Inhibition of somatic motor neurons of the external urinary sphincter results in relaxation of the sphincter to facilitate the act of urination.
The answer is; Jane would be right.
The atom was discovered be more of empty space. The mass of an atom is mainly attributed to the mass of the nucleus which occupies a very small fraction of the size of the atom. The nucleus is Located in the center surrounded by orbiting electrons.
The Geiger–Marsden experiment, where alpha particles are accelerated onto a thin aluminum foil proved this theory by Ernest Rutherford. Some of the particles were deflected by the foil and this was attributed to the dense nucleus of the aluminum atoms in the foil. The other particles passed through because most of the atoms are made of empty space.
