2.)Semolina flour differs from white flour in the way it's processed and the type of wheat that's used. Semolina is made with grooved steel rollers. The rollers crack the starch of wheat kernels into coarse pieces which is then ground into flour. The starch itself is the semolina.
3.) Whole Wheat flour or Whole grain flour is milled from the complete seed and nothing is removed. This adds not only fiber but all the minerals and vitamins in the different layers of the wheat seed.

What is primarily responsible for holding two nitrogen atoms together in a molecule of nitrogen gas?
O A. Ionic bonds
O B. covalent bonds
O c. hydrogen bonds
O D. van der Waals forces
Answers
The answer is B Nitrogen atoms will form three covalent bonds (also called triple covalent) between two atoms of nitrogen because each nitrogen atom needs three electrons to fill its outermost shell. Another example of a nonpolar covalent bond is found in the methane (CH4) molecule.

What impact does bleached coral have on the ecosystem in which it lives?
Answers
Answer:
Bleached corals are likely to have reduced growth rates, decreased reproductive capacity, increased susceptibility to diseases and elevated mortality rates. Changes in coral community composition can occur when more susceptible species are killed by bleaching events.
Bleached corals are more likely to have slower growth rates, fewer eggs, a lower ability to resist disease, and higher mortality rates.When more vulnerable species are wiped out by bleaching events, changes in the composition of the coral ecosystem might result.
What is coral reef ?Coral reefs are the most diverse ecosystem in the world providing habitat to aquatic livings. The coral pulps are made of calcium carbonate. Coral bleaching and the related mortality not only harm coral populations, but also fish communities, human communities, and other living things that depend on coral reefs and associated fisheries for their survival.
The species that rely on coral communities, like as fish and invertebrates that need living coral for food, shelter, or spawning grounds, are also impacted by changes to these communities.
When corals die as a result of coral bleaching, there may be changes in the abundance and makeup of reef fish assemblages. When corals perish due to bleaching, genetic and species diversity may be reduced.

Which type of rock has a coarse texture due to slow cooling in magma chambers?
extrusive
intrusive
metamorphic
sedimentary
Answers
Answer:
Intrusive
Explanation:
The intrusive rocks are also called as the plutonic rock. It is also considered as an igneous rock like granite and diorite. The rock which has a coarse texture due to slow cooling in magma chambers is intrusive rock. The correct option is B.
What is intrusive rock?The intrusive rocks are formed when the magma penetrates some of the existing rock structures, it crystallizes and solidifies below the surface to produce intrusions and coarse texture. Hence the name called intrusive rocks.
There are two ways in which the igneous rocks can be formed which are the intrusion and extrusion of magma. When the magma is passed through the intrusions inside the Earth's crust it forms the intrusive rocks. Granites, sills, etc. are examples.
The intrusive rocks are highly characterized by the size, shape and texture of the crystals.
Thus the correct option is B.
