Answer:
The main function of the meristem is to trigger the growth of new cells in young seedlings at the tips of roots and shoots and forming buds.
If each subunit of a hemoglobin protein molecule carries a heme group and a hemoglobin protein molecule is made of four subunits, two α and two β, we can simply multiply four (number of heme groups that can be found in one hemoglobin protein molecule) by three (number of hemoglobin protein molecules considered). 4×3=12
There are twelve heme groups in three hemoglobin protein molecules.
Answer: bryophytes
Mosses belongs to the division of Bryophytes. These are small plants that are flowerless. They typically grows in mats. They often grow in damp and shady locations. The plants exhibit simple leaves that are only one cell thick, that are attached to a stem that may be branched or unbranched and performs very little role in conduction of water and minerals.
Long one hope this helps!
A command economy is one in which a centralized government controls the means of production. The government determines what is produced, how it is produced and how it is distributed. Private enterprise does not exist in a command economy. The government employs all workers and unilaterally determines their wages and job duties. There are advantages and disadvantages of command economy structures. Command economy advantages include low levels of inequality and unemployment and the common good replacing profit as the primary incentive of production. Command economy disadvantages include lack of competition and lack of efficiency.

Unlike the invisible hand of the free market, which cannot be manipulated by a single company or individual, a command economy government can set wages and job openings to create an unemployment rate and wage distribution that it sees fit.
Whereas the motivation for profit drives most business decisions in a free market economy, it is a non-factor in a command economy. A command economy government, therefore, can tailor products and services to benefit the common good without regard to profits and losses. For example, most true command economy governments, such as Cuba, offer free, universal health care coverage to their citizens.
Command economies sit at a disadvantage as their inherent lack of competition hinders innovation and keeps prices from resting at an optimal level for consumers. Although those who favor government control criticize private firms that esteem profit above all else, it is undeniable that profit is a great motivator and drives innovation. For this reason, most advancements in medicine and technology have come from countries with free market economies, such as the United States and Japan.
Efficiency is also compromised when the government acts as a monolith, controlling every aspect of a country's economy. The nature of competition forces private companies in a free market economy to minimize red tape and keep operating and administrative costs to a minimum. If they get too bogged down with these expenses, they achieve lower profits or have to raise prices to meet expenses; ultimately, they are driven out of the market by competitors capable of operating more efficiently. Production in command economies is notoriously inefficient as the government feels no pressure from competitors or price-conscious consumers to cut costs or streamline operations.
