What is Tissue Culture?

Tissue culture is the process of growth of tissues or cells in an artificial medium that is separate from the parent organism. This technique is also known as micropropagation method. It is typically facilitated via the use of a liquid, a semi-solid, or a solid growth medium, such as the broth or agar medium.

Tissue culture is used widely in science for the propagation of plants, in the study of medicines such as those related to cancer. Tissue culture can be used as a treatment option in cancer as this technique does not show any harmful or ineffective medication. The cultured tissues of stem cells can be used for replacement of infected cells or body parts.

Therefore, the correct option is A.

Water is participate in Redox reaction as it help in release of dihydrogen molecules easily, the dielectric constant  is also high, form the connections with other chemical compounds known as hydrates.

The temperature below   4 degrees Celsius the water  ordinarily behaves, when it is cooled further, its unusual properties of water molecule are being observed.

During cooled condition,  the density of water can also slowly increases and further cooled down leads to decrease in the density of water and the expansion of matter  called as the anomalous property of water.

How is DNA expression regulated in individual cells?

Answers

Answer:

Gene regulation can occur at any point during gene expression, but most commonly occurs at the level of transcription (when the information in a gene's DNA is transferred to mRNA). Signals from the environment or from other cells activate proteins called transcription factors.

Explanation:

Gene regulation can take place at any stage of gene expression, although it often happens during transcription when the data from a gene's DNA is converted to mRNA.

What is gene regulation?

Proteins known as transcription factors are activated by signals from the environment or from other cells.

Limiting the amount of mRNA that is generated from a certain gene regulates transcription.

Eukaryotic gene expression is regulated by the nucleus-based mechanisms of transcription and RNA processing and the cytoplasm-based activities of protein translation.

Therefore, the translation of mRNA into proteins is regulated by post-transcriptional processes, which constitute the second level of regulation.

5 Devise Imagine that one tree outside your
school looks unhealthy, although all the other
trees seem healthy and strong. Describe how
you could apply scientific thinking to the
situation.

Answers

The first step is to identify the problem. There are factors to consider in keeping a plant or a tree healthy. These include water, oxygen, sunlight, soil, nutrients, climate, and other environmental conditions. If the environment seems to suit the other trees in the garden, ruling out other factors can be useful in determining why only one tree seems to be unhealthy. Once the problem is identified, a scientific investigation must be done to gather data and pieces of evidence which can explain why this event actually occurred. One of the best ways to gather evidence is through observing the tree and checking other signs which might identify if the tree is diseased. Once the gathered data are analyzed and the cause is identified, proceed in thinking of ways on how to solve it. In seeking a solution, it is best to ask information from experts and proper authorities.
