<h2>
<u>STATEMENTS</u></h2>
The correct statement among the given answers is letter <u>d. an object in motion will remain in motion.</u>
<h2>
<u>WHY? </u></h2>
In reality, object that is in motion (like a ball) will remain in motion unless it's stopped by something (a wall or any force).
This is stated in the first law of motion by Sir Isaac Newton -- an object in motion will remain in motion unless an outside force acted upon the object.
Cellular respiration : aerobic :: fermentation : anaerobic
Answer:
The term unicellular and multicellular describe how living things are organized.
Explanation:
The number of cells in living things determine how the body organization will be.
Living things are made up of cells in which there are two types of living cells. We have the unicellular and multicellular cells.
The unicellular are made up of one cell (single cell) the unicellular organisms are simple cells which make their functions simple while the multicellular organisms are made up of two or more organisms and their functions are special unlike the unicellular which the functions are simple
Answer: When wilted plants are given water, it enters the cell generating turgor and giving a firmer appearance, and this water is stored in the vacuoles.
Explanation:
Turgor is a phenomenon in plant cells in which the cell expands due to the pressure exerted by the fluids and also by the cell content on the walls. It is related to osmosis, since the external pressure is usually very high and this internal pressure dilates the cell as much as the elasticity of the membranes allows. <u>Then, the cells swell by absorbing water, tensing the membranes because of the pressure against them.</u> When the fluid exerts outward pressure on the cell wall it is called turgor pressure. Whereas, the inward pressure exerted on the cell contents by the stretched cell wall is called wall pressure. Generally, both pressures, turgor pressure and wall pressure, are counterbalanced and balanced.
So, this pressure of turgor facilitates the elongation of the cells in the plant, and also, the cells use this phenomenon to regulate the transpiration through the opening and closing of the stomach.
Thereby, the turgor of a living cell is influenced by three primary factors:
- An adequate supply of water.
- The formation of osmotically substances.
- A semi-permeable membrane.
Vacuoles are organelles bounded by a single membrane and present in plant and fungal cells, and where water is stored. Plant cells control their turgor pressure through the movement of water into or out of vacuoles. When wilted plants are given water, it enters the cell generating turgor and giving a firmer appearance, and this water is stored in the vacuoles.
