Answer:
The correct option is A. mRNA.
Explanation:
mRNA is a single stranded RNA molecule, complementary to one of the DNA strands of a gene. Also known as messenger RNA, mRNA is synthesized in the nucleus and then exported to the cytoplasm, where the translation machinery (the machinery that actually makes the proteins), binds to the mRNA molecules and reads in them the code to produce a protein specific. During protein synthesis, an organelle called a ribosome moves along the mRNA, reads its sequence of bases, and uses the genetic code to translate each triplet of three bases or codon, into its corresponding amino acid.
The group in an experiment that all the conditions stay the same is the control group.
The component of urinalysis that reflects the amount of waste products and solids in urine is called Specific Gravity
A urine test examines the various elements in urine.
The kidneys filter the blood to remove waste products, minerals, water, and other chemicals that are then excreted in the urine. There are countless distinct bodily wastes in urine.
Urine can be used in more than 100 different tests. The tests for color, clarity, odor and specific gravity are frequently performed as part of a routine urinalysis.
The amount of chemicals in the urine is measured using specific gravity. Additionally, it demonstrates how effectively the kidneys regulate the amount of water in urine.
The more solid stuff there is in the urine, the greater its specific gravity. When you consume a lot of liquids, your kidneys produce urine with low specific gravity and high water content. Your kidneys produce urine with high specific gravity and little water when you don't drink any fluids.

Answer:
A) Tissue
Explanation:
Cells are the basic and fundamental units of all living organisms. Plants, like every other multicellular living organisms, are composed of cells that perform different functions. A group of cells that perform similar functions make up or form TISSUES, tissues that work together form the ORGAN, organs that work together to perform same function form the ORGAN SYSTEM.
In plants, sieve tubes and companion cells work together to carry out a similar task in plants, which is to transport nutrients and sugar inside the plant. Since sieve tubes and companion cells work together to fulfil same task, they collectively form a tissue in plants called PHLOEM tissue.
The structure being described is the tricuspid valve.The right atrium is one of the two atria of the heart which function by receiving blood entering the heart, it is located to the right of the left atrium and superior to the much larger and more muscular right ventricle. Between the right atrium and right ventricle is a one way valve known as the tricuspid valve.
