A is correct. We know that water buildup is essential for plants (and all other organisms) that live in the desert due to its lack of moisture. So, the question is simply asking which adaptation will help a plant retain the most water in the desert. Here’s what makes each wrong or right:
A. Stem that stores water - Having stems that can retain a lot of moisture and water is absolutely necessary for plants that live in hot and dry biomes. The brief periods of rain in the desert make it easier for plants with water-storing stems to absorb the water and remain hydrated throughout their time. This is referred to as succulence, and most (if not all) plants in the desert are succulents. This is the correct answer!
B. Shallow root system - Many plants that live in deserts tend to have shallow root systems that allow them to quickly absorb and moisture in the environment — and because water never goes too far in the desert, they soak most of it up. Although this is helpful, it is better for plants that live in places with a lot of soil.
C. Large surface area - Having a large surface area is more useful for photosynthesis and may result in dehydration. This is wrong!
D. Flat broad leaves - Again, this adaptation is more favorable for plants that do not live in the desert because, as we know, photosynthesis requires water.
Answer:
Option C, Estuary
Explanation:
<em><u>An estuary is a geographical entity where the salty water of ocean mixes with fresh water of river. The resulting water is known as brackish water. The brackish water is not as salty as that of ocean and also the salinity level of water rise and fall regularly.</u></em>
<em><u /></em>
<em><u>Thus, an organism that is able to live in both salty water and fresh water environment can survive in an estuary.</u></em>
<em><u /></em>
<em><u>Hence, option C is correct</u></em>
Answer:
See Explanation
Explanation:
1. Clastic sedimentary rocks which is composed of fragments of preexisting rocks and minerals.
3. Formation of oxides takes place, except the noble gases Oxygen form oxides with all other elements. For example, oxide of hydrogen, silicon dioxide,etc.
6. Weathering is defined as the chemical and physical breakdown of rocks.
8. Acetic and citric acid dissolves calcite. However, it can also be dissolved by groundwater depending upon the factors such as temperature of water, pH value of water and concentration of ions dissolved.
10. Grinding away of rock with other rocks is called Abrasion. It is mainly caused by movement of wind and on surface stone or rocks against the surface of rock.
13. It is Chemical weathering which breaks down the rocks and also changes mineral composition of newly formed rock from it's parent rock.
14. These broken pieces of rocks are called sediments and word sedimentary is derived from sediments.
16. Soil is defined as the mixture of weathered rocks and organic material. Soil is produced from process of weathering and and natural erosion.
17. Rock forming minerals include fled-spars, calcite, quartz, mica, dolomite, etc.
