Biology
1 answer:
Aleks04 [339]3 years ago
3 0

Answer:

Some such means, like diffusion and osmosis, are natural processes that require no expenditure of energy from the cell and are called passive transport. Other methods of transport do require cellular energy and are called active transport.

What problems still exist in using natural regeneration?
qwelly [4]
Natural regeneration of forests and woodlands is the process by which new trees grow from seeds that have fallen and germinate where they have fallen.  The biggest problem with natural regeneration is that is unpredictable.  As a result, it cannot be used for commercial farming. For most of the last two or three hundred years, forests and woodlands have restocked by using transplants grown in nurseries. The young trees are planted in equidistant rows. This allows each tree the best possible change of optimal growth.

What is free nitrogen?
UNO [17]

Answer:

Nitrogen thet cannot be used by organisms. C.

Explanation:

Free nitrogen is simply molecular nitrogen (N2). Nitrogen, in its molecular form, consists of two nitrogen atoms bound together with a tripple bond. Because it is very stable, N2 is typically nonreactive, and takes a lot of energy to break them apart. Among these are the amino acids necessary for life to begin and which are the building blocks DNA is made from. Basically, any nitrogen that is in an organic compound is considered “fixed” nitrogen and N2 is considered to be “free” nitrogen

Four bands appear in gel electrophoresis. Gel electrophoresis is an experimental method used to separate mixtures of DNA, RNA, or proteins by molecular size.

DNA is negatively charged, so when a current is applied to the gel, the DNA migrates towards the positively charged electrode. Fragments are ordered by size because short DNA strands migrate through the gel faster than long strands. There are some basic steps for performing gel electrophoresis outlined below. 1) pour the gel, 2) prepare the sample, 3) load the gel, 4) run the gel (expose it to an electric field), 5) stain the gel. Gel electrophoresis is a technique for separating biomolecules by size. Separation of these molecules is achieved by placing them in a small pore gel and creating an electric field across the gel
