Answer:B,C
Explanation: covalent and ionic bonds hold molecules together. It is the polarity of covalent bonds that give rise to hydrogen bonding. As in the water example: the more electronegative O attracts electrons slightly more than the hydrogens, so the O has a fractional negative charge, the Hs a slight positive charge. The O of one molecule and the H of another are held together by this charge difference.
Answer:
D. They are genetically identical to the original cell
Explanation:
Two identical diploid daughter cells are produced by mitosis. (Diploid just means that the cells each have 23 pairs of chromosomes). Hope this helps!
Answer: Igneous
Explanation:
The main type of rock found at divergent plate boundaries is igneous. These rocks are formed when magma cools and becomes solid, either above or below ground. They are rich in elements including silicon, aluminium, sodium, potassium, calcium and iron, and make up about 95 percent of the upper part of the Earth's crust. More than 700 types of igneous rock have been identified.
Most rocks formed at divergent boundaries are categorized as malefic igneous rocks, which are dark-coloured due to their high magnesium and iron content. This category includes basalt, gabbro and peridotites, which are often found at these boundaries.
Answer:
The changes in the single base or nucleotide in the nucleotide sequence and thus changing its complementary base also it is called as point mutations, while when there are insertions or deletions of more than one base pair in the nucleotide sequence it is known as frameshift mutations.
<span>Turf grasses are beautiful grasses used as lawn grasses. These are dark green in color and grow densely. Turf grasses are tolerant species and can tolerate harsh environmental conditions. Turf grasses tolerate a wide pH range but do best in slightly acidic soils. Raising pH modifying the soil with agricultural lime, also known as calcium carbonate, can be used to raise pH Level. But to be more effective, it is usually mixed in to the upper soil layer. Turf grasses grow best in the full sun when soil moisture is not limited and soil temperatures are optimal.</span>
