Answer:

Physical properties are those attributes of a material that can be observed and/or measured without changing the composition or identity of that material. Examples of such properties include color, smell, freezing point, melting point, viscosity, opacity. density, solubility, polarity, texture and many others.

Now if the behavior of a material is inherent to that material, and is an attribute that can be observed or measured without effecting any chemical change in that material, then it may very well be considered a physical property of that material.

For example if a particular element or material melts at 40 degrees centigrade, this is a behavior of that element and is considered a physical attribute.

How the DNA is different from the cDNA?

Alexandra [31]

Answer:

gDNA = "genomic DNA" and cDNA = "complementary DNA." cDNA is classically associated with being reverse transcribed either from all extracted RNA from a tissue or cell (total RNA) including (in eukaryotes) pre-mRNA, ribosomal RNA, tRNA, snoRNA, miRNA and mRNA, etc.) while cDNA obtained only from reverse transcription of the mRNA (expressed eukaryotic cytosolic mRNA) fraction (e.g., by poly[dT]n and random priming) is complementary DNA (cDNA) made from what is called the "transcriptome." Eukaryotes have introns and exons in the gDNA, while prokaryotes do not. So eukaryotic cDNA reverse transcribed from mRNA lacks introns. Prokaryotic-derived cDNA is always complementary to prokaryotic RNA and gDNA (so is always necessary to have a good DNase treatment prior to gene expression analysis by e.g., qPCR for prokaryotic transcriptome work)...

Answer:

Explanation:

Respiration can happen without sunlight,but photosynthesis cannot.and photosynthesis doesn't take place at night,so less carbon dioxide is used up than it is produced.

Some plants increase in height due to changes in specialized regions of cells in the tips of their branches. The processes that

Nookie1986 [14]

Answer:

mitosis, cell growth, and differentiation

Explanation:

There are several ways through which plants grow which may include the process of mitosis mainly that involves cell division. The increase in height in plants is attributed to not only cell division but also growth of the newly formed cell.

Mitosis involved division of cell and in cell growth, cells increase their size that ultimately cause growth of plant height. The highly active growth cells are meristem cells that are found at tips of the plants. They are actively dividing zones of plants and with their division and growth plant increases their heights.

Another mechanism, responsible for increase in height is cell differentiation. Differentiation is the process during which cells are specialized to perform specialized function. For example: Xylem are specialized for transport of water. Phloem are specialized for the transport of food. Similarly, some cells are specialized for growth and they are aimed at increasing in size and division that ultimately increase the plant height.

So, mitosis, cell growth, and differentiation are the mechanisms, that increase plant height due to changes in specialized regions of cells in the tips of their branches.

Hope it helps!
