Ans.
Platelets are a type of blood cells, responsible for blood clotting. These cells prevent excessive blood loss from wound as they form plug or clot at the site of injury to repair the damage. Thus, the option). platelets is correctly matched with 'clotting blood.'
White blood cells or WBCs are components of immune system that protect the body from harmful foreign molecules, such as bacteria, fungi, and viruses and harmful body cells, such as tumor cells. Thus, the option). white blood cells is correctly matched with 'fighting bacteria.'
Red blood cells or RBCs are blood cells that transport oxygen, carbon dioxide, and nutrients to the different part of the body. These cells are made up of hemoglobin and protein. Thus, the option). red blood cells is correctly matched with 'clotting blood.'
Plasma is the non-cellular, colorless, fluid portion of blood, composed of proteins, vitamins, antibodies, amino acids, and other micromolecules. It is responsible for viscous nature of blood. Thus, the option). plasma is correctly matched with 'providing viscosity to the blood.'
Answer:
The answer is A.
Explanation:
The bacteriophage is an organism that attacks bacteria and uses them to replicate it's DNA to reproduce and multiply.
If all the amino acids of the bacteria are flagged with fluorescent tag, then the new bacteriophage's DNA will exhibit the fluorescent tag because it will be constructed using the bacteria's protein molecules in the first place. So the answer is A.
I hope this helps.
Meningocele
Meningocele (MM) is known as meningeal cyst and it is the protrusion
of the membrane that cover the part of spinal cord through the defect in the
vertebral column. Thus, Meningocele (MM) is the least
common fom of spinal bifida and spina bifida is the bony defect in the
vertebral column through the meningeal membrane.
Wavelength light source is part of the control group for William’s experiment
<u>Explanation:</u>
Sir William wanted to conduct an experiment to observe how much heat passed through different colour filters of the sunlight. He directed sunlight to pass through the prism and observed vibgyor and measured the temperature. He found that the temperature increased from violet to red.
Then he was inquisitive to find the temperature beyond the red ray. That’s when he found the infrared rays which had higher temperature that was not to be seen through naked eyes. He performed experiments using the light source and found that the wavelength of light are not refracted in a particular pattern.
