How are vascular and non-vascular plants different, and how do each of them work through osmosis?
Lilit [14]

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.

Which of these is a piece of evidence supporting the theory of evolution?
ycow [4]

The C option is Correct.

  • All the Galapagos finches exist on the same island.

Galapagos finches is a piece of evidence supporting the theory of evolution.

Darwin's finches comprise a group of 15 species endemic to the Galápagos (14 species) and Cocos (1 species) Islands in the Pacific Ocean. The group is monophyletic and originated from an ancestral species that reached the Galápagos Archipelago from Central or South America.

On his visit to the Galapagos Islands, Charles Darwin discovered several species of finches that varied from island to island, which helped him to develop his theory of natural selection.

svetlana [45]

The epigastric region is a portion of the <u>abdominal </u>cavity.

The correct option is d.

The greatest hollow area in the body is the abdominal cavity. Its lower limit is the upper plane of the pelvic cavity, and its upper barrier is the diaphragm, a sheet of muscle and connective tissue that divides it from the chest cavity. The spinal column, as well as the abdomen and other muscles, encircle it vertically.

The epigastrium is the top portion of your abdomen that is immediately below your rib cage. The epigastrium houses your pancreas and the duodenum, a section of your small intestine. Additionally, your stomach and liver are partially located here.
