i dont understand what do you mean. theres a spelling mistake
Explanation:
Answer:
Pulmonary fibrosis is a disease that affects the lungs. The lung tissue becomes damaged and scarred which causes it to be thickened and stiff.
The condition pulmonary fibrosis is caused by the replacement of elastic fibers in the lung with inelastic collagen fibers. This decreases the lungs’ ability to stretch outwards.
Pulmonary fibrosis however mainly affects inspiration because the lungs cannot stretch to increase volume while during expiration stretching of the tissues doesn’t happen so it doesn’t affect the process.
<span>1.<span>Understanding life. Primarily, studying biology gives you the essentials
and primal knowledge of life and how and what you can perceive from it, may it
be various fields of zoology, botany or anthropology, psychology, sociology and
etc. It lets you understand the different anatomies, physiologies and
behaviours on how they act independently, interact and influence one another. </span></span>
<span>2.Protecting life. It provides a sense of preserving life as your upmost
goal in studying biology. You came to an actualization to delve into this science
as to be a steward and a developer.</span>
<span>
3.Responsibility. It comes with ethics. You become concerned with how
actions of a certain populace of a species can affect the entire ecosystem.
Human behavior has massive effects to the biosphere.</span>
<span>4.Advancement. The improvement and enhancement on how we can preserve and
understand life and the human populace develop and utilize the earth without
damaging its vital components.</span>
<span>5.Involve in the current issues and participate. You can be part of a
responsible scientist and individual, a citizen of science to stop and help grow
the serious concerns of today’s abusive human behaviours and life-threating concerns.</span>
Answer:
Primary succession begins with soil formation. The first stage of succession involves pioneer species. In primary succession, pioneer plants are those that can grow without soil, such as lichens. Lichens begin breaking down a rock.
Hi,
Recombinant DNA technology is the process in which a target gene of interest is replicated by inserting it into a vector and creating a recombinant DNA. This recombinant DNA is then returned into an expression system where it is replicated several times to give rise to multiple copies of our desired gene or that gene product.
One of the very important role for the execution of this technology is performed by Restriction endonuclease enzymes. These are the enzymes that have ability to cut the DNA fragment at specific sequence into fragments of different lengths called restriction fragments.
- They play a very important role in recombinant DNA technology:
- They can map the location of specific restriction sites where the target sequence is identified and cleaved.
- They cut down the DNA at specific sites called restriction sites. The host DNA in which foreign gene or target gene is inserted is also cut with the same restriction enzymes. So in the recombinant DNA technology, restriction enzymes act like a molecular scissor which identify and cut certain DNA sequences as per or requirement.
- The target sequence can be cut from multiple places by restriction enzymes since our target sequence can be present multiple times in the DNA of organism.
- When restriction enzymes cut the DNA, they leave sticky or blunt ends at that site in such a way that these ends are able to bind with the complementary bases of vector DNA when introduced.
- Then another enzyme DNA ligase seals the ends of target DNA and vector DNA making a whole recombinant DNA that is ready to be cloned and progress further steps of recombinant DNA technology.
