Answer:

<h2> Parenchyma simple tissues: </h2>

Cells of parenchyma tissues live. They are oval, elongated and loosely packed with large inter-cellular space, forming basic packing of tissue and found throughout the plant body. Functions of parenchyma: They provide mechanical support to the plant body. They store food and nutrients in vacuoles.

<h2>Collenchyma simple Tissues: </h2>

Cells of collenchyma are live. They are oval and elongated and tighily packed with no inter-cellular spaces. They epidermis in leaves and stem. Functions of collenchymas tissues: They provides mechanical support to plant. They also provide flexibility to plants so that they can bend without breaking.

Isolationism was strong during the first half of 1930's due to the series of events .

Briefly discuss the current controversy about which complex organic molecules formed first: nucleic acids or proteins

Romashka-Z-Leto [24]

The controversy surrounding the nucleic acids and proteins, regarding which one of them was formed first is the most popular controversy in the biology world today. The nucleic acids stores and the genetic information. The proteins essential for all the life processes are encoded by the genes formed of the nucleic acids (DNA and RNA). But proteins (enzymes) are required for the formation of proteins from the genes. The inter-dependency of the nucleic acids and proteins on each other possesses a dilemma to the question 'which of them arrived first'.

The answer to this dilemma was answered when it was discovered that RNA was capable of not only carrying the genetic information, but also acting as catalyst to the chemical reaction. This finding supported the notion that the RNA evolved first serving the purpose of both the nucleic acids and emzymes.

Explain the difference between types of scientific investigation

allsm [11]

Answer:

Hey there.

There are three types of scientific investigations: descriptive, comparative, and experimental scenitific investigations.

fist we have Descriptive scientific investigations.

Descriptive investigations use careful observations and measurements to develop findings.

Then we have  comparative Investigation.

comparative investigations Involve collecting data on different populations/organisms, under different conditions (Times of year, locations), to make a comparison. for Example, Using a hand lens to examine the color and texture of four different rocks.

Lastly we have experimental scientific investigations.

Experimental investigations involve a process in which a "fair test" is designed and variables are actively manipulated, controlled,

"In genetic modifications, DNA inserted can come from _____ ." any organism containing the DNA of interest only the same plasmid

liq [111]

Answer:

<h2> any organism containing the DNA of interest</h2>

Explanation:

Such type of process in which the modification of the genes of the organisms takes place is known as genetic modification and also called genetic manipulation or genetic engineering.
In such type of the process, the branch of biological science that is known as biotechnology is used.
In this mechanism, genes of interest are separated from the certain organism and then this gene of interest is inserted into the host organism and such type of DNA that is formed after the addition of foreign genes or DNA is called recombinant DNA.
Such type of DNA is used in the production of genetically modified organisms and some other fields for the benefit of human beings.
