Virus are made with ADN or RNA only, which both of them has the information of replication. Once that the virus is in a cell, this ADN or RNA will be deposit inside the cell at the replication system that is going to make the virus reproduce unlimited times until the membranes of the cell break down. And they are useful because you can use them as a carrier or vector for treat diseases or for transgenics, bioterrorism, and so on.
A is correct is the answer
Answer:
Explanation:
Vascular plants have tubelike structures that carry water, nutrients, and other substances throughout the plant. Nonvascular plants do not have these tubelike structures and use other ways to move water and substances.
Vascular plants are said to have a true stem, leaves, and roots due to the presence of vascular tissues. Non-vascular plants do not have true roots, stems, or leaves and the tissues present are the least specialized forms of tissue. Some examples of vascular plants include maize, mustard, rose, cycad, ferns, clubmosses, grasses. Some examples of non-vascular plants include moss, algae, liverwort, and hornwort.
How vascular plants work through osmosis
The xylem of vascular plants consists of dead cells placed end to end that form tunnels through which water and minerals move upward from the roots to the rest of the plant. Through the xylem vessels, water enters and leaves cells through osmosis.
How non vascular plants work through osmosis
Because non vascular plants do not have the xylem and phloem ystem, they absorb water right into their cells through their leaves when it rains or when dew falls. Internal cells get their water by passive osmosis. While, they use rhizoids to transport nutrients and minerals.
Answer:
4
Explanation:
If we have the expression, 3/3/4.
Then this is the same as 3 × 4/3
Which is the same as 12/3
Which is the same as 4
Hence the value of the expression 3/3/4 is 4
Answer:
The correct answer is duodenum
Explanation:
Bile is a digestive enzyme that is secreted by the liver which is temporarily stored in the gall bladder and pancreatic enzyme is released by the pancreas. The bile is secreted to the small intestine through the common bile duct and the pancreatic duct joins the common bile duct just before ampulla of Vater which opens in the first intestinal portion which is duodenum.
So bile and pancreatic enzymes enters the duodenum region of the small intestine and after getting in the small intestine it digests the complex macromolecules into simpler and smaller form which can be absorbed through the intestinal epithelium.
