what is the question u need to answer???
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.
Humans are diploid organisms that have 23
pairs of chromosomes (or 46 chromosomes) in
all somatic or body cells. These cells divide by
mitosis that forms daughter cells with same
number of chromosome pairs as present in
parent cell.
In humans, gametes (eggs and sperms) are
formed from the germ cells by the process of
meiosis that leads to reduction of chromosomes
in daughter cells (with half the number of
chromosomes as present in parent cell).
Thus, the correct options are:
-bone cell has 46 chromosomes, as bone is a
somatic cell.
-Skin cell has 23 chromosome pairs (46
chromosomes), as skin cell is somatic cell.
-gamete has half the chromosomes (23
chromosomes) of a red blood cell (46
chromosomes) as red blood cell is somatic cell.
Answer:
Option A
Explanation:
Starch is a example of a "lipid" or option A. Starch are also a example of a natural polymers and natural polymers are organic substances that are insoluble in water but soluble in other organic mixtures and a example of a natural polymer is starch.
Hope this helps.
