Answer:
D) Enzymes make nonspontaneous reactions become spontaneous
Explanation:
Being spontaneous or non-spontaneous in nature depends on the difference in energy levels between substrates and products of the reactions. A reaction with substrates at higher energy levels than the products are spontaneous ones. On the other hand, the reactions wherein products have higher energy content than the substrates are non-spontaneous.
Enzymes do not change the energy levels of substrates and products, so, they can not make a non-spontaneous reaction to become a spontaneous one. Enzymes only lower down the activation energy for a reaction and thereby make the non-spontaneous reaction to occur at a faster rate.
Answer :Meristems contribute to both primary (taller/longer) and secondary (wider) growth.
Explanation:
Primary growth is controlled by root apical meristems or shoot apical meristems, while secondary growth is controlled by the two lateral meristems, called the vascular cambium and the cork cambium.
Answer:
meiosis
Explanation:
meiosis occurs in reproductive organs
Answer:
B
Explanation:
.... I'm not sure tho.. Sry
Answer:
e. The statement is true for meiosis I only.
Explanation:
When we talk about homologous chromosomes, we talk about two chromosomes forming a pair of genes. One comes from the mother, and one comes from the father in sexual reproduction.
The random segregation of chromosomes is what we call the result of crossing over during meiosis I, and is what generates genetically unique individuals in each reproduction.
