What kind of growth describes plant growth throughout the life of the plant?

Plant growth throughout the life of the plant is <span>a combination of cell growth (increased cell size) and cell division (increased cell number). The meristematic tissue (meristem) of the plant is responsible for the continuous growth through life. It is a type of plant tissue consisting of undifferentiated cells(meristematic cells) that can continue to divide and differentiate. Meristematic tissue is located in zones of the plant where growth can take place and because of that, there are three types of meristematic tissues: apical, intercalary (at middle) and lateral. Primary meristem allows growth in length or height (primary growth) and in woody plants secondary meristems allows growth in diameter (secondary growth).</span>

A substance floats if it is less dense, or has less mass per unit volume, than other components in a mixture. For example, if you toss a handful of rocks into a bucket of water, the rocks, which are dense compared to the water, will sink. The water, which is less dense than the rocks, will float. Basically, the rocks push the water out of the way or displace it. For an object to be able to float, it has to displace a weight of fluid equal to its own weight.

Water reaches its maximum density at 4 C (40 F). As it cools further and freezes into ice, it actually becomes less dense. On the other hand, most substances are most dense in their solid (frozen) state than in their liquid state. Water is different because of hydrogen bonding.

What do amino acids, fatty acids, and sugars (monosaccharides) have in common?

MariettaO [177]

What amino acids, fatty acids, and sugars (monosaccharides) have in common is that they are made of carbon, oxygen, and hydrogen which is option B.

Amino acids are the basic structural units of proteins. Each amino group (-NH₂) and a carboxyl group (-COOH) in its molecule. Thus, from the molecular structure of an amino acid, the carboxyl group of the molecule contains carbon, oxygen and hydrogen elements.

Fatty acids are commonly found in lipids ans are made up of long chain alkanoic acids of general formular, RCOOH where R contains about 10 to 18 carbon atoms. the terminal -COOH group contains carbon, oxygen and hydrogen elements.

Sugars (monosaccharides): they are naturally occuring organic compounds containing carbon, hydrogen and oxygen, with the hydrogen and oxygen present in the ratio of 2:1. The general formula for monosaccharides is C₆H₆O₁₂.

Therefore, amino acids, fatty acids, and sugars (monosaccharides) have carbon, oxygen, and hydrogen in common.
