If you apply white light and it reflects only red, you see it red, all the other wavelentghs absorbed. If it reflects all wavelength (i think listed all red-orange....) then it should be white.
The right answers are on the attached image.
Baroreflex is a reflex triggered when a baroreceptor is stimulated. In the human body, baroreceptors are found in the carotid sinuses and the sinus of the aorta. These receptors are stimulated during changes in blood pressure. Baroreceptors are sensitive to the stretching of blood vessels.
As blood pressure rises, baroreceptors transmit nerve impulses to the vasomotor center of the medulla oblongata, which is then inhibited. This results in vasodilatation of the blood vessels to reduce blood pressure.
Answer:
<h2>
B) demonstrated that the nuclei from all the differentiated mammalian cells can retain their full genetic potential.
</h2>
Explanation:
Every cell of an organism contain equal number of chromosomes, like nerve cell, mammary gland cell, muscle cell, heart cell etc. all have same number of chromosome and equal amount of DNA. The morphology and functioning of different cell depends on the differential gene expression.
Cell express their genes according to the requirement or the environment or according to the signals.
The cloning of Dolly demonstrated that the nuclei from all the various differentiated mammalian cells can retain their full genetic potential.
Which of these proteins in mammals show only primary and secondary
structures - Keratin. Proteins like keratin are made up of multiple
peptide chains (polypeptide); these are group of amino acids joined by
peptide bonds. [ The sequence of amino acids in a protein is the
primary structure while the specific shape in which it is folded (alpha
or beta) is called the secondary
