The following diagram demonstrates the flow of water when a cell is placed in different aqueous solutions. Review the labels at the top of each picture. If a marine plant is placed in a salt water aquarium, predict the flow of water and salt into/out of the plant's cells.

Answers

A simple solution is basically two substances that are evenly mixed together. One of them is called the solute and the other is the solvent. A solute is the substance to be dissolved (salt). The solvent is the one doing the dissolving (water). If the cell is placed into a salt water solution, the salt will replace the water (standard osmosis laws), but if there is very little or no salt, then water replaces the salt.

B) Because the solution is isotonic, there will be no net movement of either water or salt.

The transport tissues of vascular plants are the _____ and _____. xylem; cortex phloem; pith xylem; phloem parenchyma; collenchyma

Answers

The answer is xylem and phloem.

Xylem and phloem are the transport tissues of vascular plants. Parenchyma and collenchyma are ground tissue, while pith and cortex are stem tissue.
Xylem and phloem provide transportation of water, minerals, food, and nutrients. Xylem transport water and minerals from the root to the upper parts of the plant. Phloem transports food and nutrients from the leaves, where they are produced, to the growing or storage parts of the plants.

What can be said about prokaryotes and eukaroytes?a. Prokaryotes always have a nucleus, but eukaryotes don't.
b. Both of these cell types contain a nucleus.
c. Eukaryotes always have a cell membrane, but prokaryotes don't.
d. Both of these cell types contain genetic material.

Answers

Eukaryotes always have a cell membrane, but prokaryotes don't. Eukaryotic and Prokaryotic cells are bothbuilding blocks of life in different organisms. The main difference of two isin its structures. Eukaryotic cells contain organelles that are foundinside membranes, like the nucleus, which stores chromosomes and DNA.Prokaryotic cells don't have a nucleus and no true chromosomes. Prokaryotic cellsare unicellular while eukaryotes are multicellular. The presence ofmitochondria, chloroplasts, and cell wall are all distinct to Eukaryotic cells.Eukaryotic cells are found in animals and plants, while bacteria and archaeahave prokaryotic cells.

In terms of existence, prokaryotes have been onEarth for millions of years; while eukrayotic cells have come to existencethrough the process of evolution.

What will the continued depletion of the ozone layer most likely cause?
