Part b - comparing eukaryotic and prokaryotic cells two fundamental types of cells are known to exist in nature: prokaryotic cel

Alexeev081 [22]

<h3>Answer;</h3>

Prokaryotic only: nucleoid
Eukaryotic only: nucleolus, lysosome, mitochondria
Both: plasma membrane, ribosomes, flagelia

<h3>Explanation;</h3>

Prokaryotic cells are those cells that lack nucleus and other membrane bound organelles, unlike eukaryotic cells which contain a membrane bound nucleus and membrane bound organelles such as mitochondria, and lysosomes.
Prokaryotic cells lack the nucleus and nucleolus, but instead contain a nucleoid which contains the genetic materials of the cell.
Eukaryotic cells on the other hand contain a well defined nucleus, that contains nucleolus and highly complex genetic material.
Despite the differences, they both share a number of organelles and characteristics such as plasma membrane, which regulates the movement of substances in and out of the cells, ribosomes, sites for protein synthesis, and also flagella, for locomotion.

Choose a plant tissue. Write an explanation of how that tissue’s structure relates to its function. Be specific and detailed.

yawa3891 [41]

There are two types of plant tissues: meristematic tissue found in plant regions of continuous cell division and growth, and permanent (or non-meristematic) tissue consisting of cells that are no longer actively dividing.Meristems produce cells that differentiate into three secondary tissue types: dermal tissue which covers and protects the plant, vascular tissue which transports water, minerals, and sugars and ground tissue which serves as a site for photosynthesis, supports vascular tissue, and stores nutrients.Vascular tissue is made of xylem tissue which transports water and nutrients from the roots to different parts of the plant and phloem tissue which transports organic compounds from the site of photosynthesis to other parts of the plant.The xylem and phloem always lie next to each other forming a structure called a vascular bundle in stems and a vascular stele or vascular cylinder in roots.Parts of the shoot system include the vegetative parts, such as the leaves and the stems, and the reproductive parts, such as the flowers and fruits.

A gel electrophoresis was run on DNA fragments 1 megabase (MB), 2 MB, 4MB, and 7 MB in size. Identify the fragments and explain

Shalnov [3]

Answer:

7MB, 4MB, 2MB, and 1MB

Explanation:

At the completion of the electrophresis, you wills see some bands appear. If the side you have put the sample is upper and the other the down part, the you will see from above to below are 7MB, 4MB, 2MB, and 1MB.

This is due to the negatively charged molecules of DNA, so the bands moves from negative to positive sides.The negative side is the upper and the positive side is the lower side. Molecular do change the way bands are running. Heavier normally move slower than lighter bands.
