Answer: True.
Explanation:
Organic fats are nonpolar molecules, while water is a polar molecule.
Since fats do not have any polar part in its structure, to be dissolved in water they would have to break some of water's hydrogen bonds. But this does not happen, so the fat is forced to stay separate from the water. This means nonpolar molecules are repelled by water and do not dissolve in it. They are hydrophobic compounds. So the lipids just float in the water without blending into it.

B. copper and iron.
C. zinc and magnesium.
D. iron and zinc.
Answer:
Option A
Explanation:
The core of earth has two parts
a) Outer core – The outer core is made up of molten alloy of iron and nickel. However, it also has traces of dense materials like gold, platinum, and uranium etc. These materials are contained at a very high temperature i.e 9,000 and 13,000 degrees Fahrenheit.
b) Inner Core – It is composed of solid dense iron but the iron is not in its purest form. It has some impurities such as sulfur etc. It has temperature ranging between 7000 to 9000 degrees Fahrenheit and is responsible for earth's magnetic field.
Hence, option A is correct
Answer:
A
Explanation:
Soil becomes less fertile the deeper it goes because the percentage of organic matter, such as humus and living organisms, decreases with depth. This reduction results in a lower nutrient content in the soil, lessening its fertility.
The soil gets less fertile the deeper it goes due to the increased distance from organic matter. The organic material of soil, called humus, is primarily found in the upper levels of the soil. It improves the soil structure and provides water and minerals to plants. As we go deeper into the soil, the quantity of this organic matter decreases which results in the soil being less fertile. The inorganic matter which primarily forms the deeper soil layers contributes less to fertility as it mainly consists of rock and lesser nutrients.
Besides, soil has different layers called horizons, each with distinct physical and chemical properties. These horizons include the A horizon which is a mixture of organic and inorganic products of weathering, and B horizon where there is an accumulation of mostly fine materials that have moved downward. The fertility of soil decreases as we move from the A horizon to the B horizon and further down.
Biological factors also play a significant role in the fertility of soil. The presence of living organisms greatly affects soil formation and structure. However, the number and impact of these organisms decrease with soil depth, also decreasing fertility.

Answer:
anecdote
Explanation:
This report would contain his journey of change in his physiology during the stint of two months during which he took protein supplements before and after his workouts.The report will reveal how he become 200% stronger after he added the supplements to his diet. Therefore, the would be an anecdote of this amazing journey of transformation.
-halite
-mudstone
-coal
The answer is option A, limestone.
b. division.
c. differentiation.
d. specialization.
The correct answer is c.
Differentiation in prenatal development is the process of growthand development in which embryonic cells become specialized and differenttissue structures rise. Differentiation of the cells during this stage is crucialto the cell, tissue, organ, identity of the organism.
