Answer:
a. carry genetic information that influences the same traits.
Explanation:
Homologous chromosomes are the pairs of chromosomes. One chromosome of a pair is derived from the egg cell while the other comes from sperms. Two chromosomes of a pair carry the gene for the same traits. For example, two copies of chromosome 21 would carry the genes for the same traits in humans. However, these two chromosomes of a homologous pair may have the same or different alleles for a particular gene.
If chromosome 21 carries the gene for eye color in humans, the paternal chromosome may have the allele for blue eyes while the maternal chromosome may carry the allele for the black eyes. However, both of them have the "gene for the same traits (eye color)".

Answer:
Explanation:
The conversion of nitrogen gas (N2) into nitrates and nitrites through atmospheric, industrial and biological processes is called nitrogen fixation. Atmospheric nitrogen must be processed, or "fixed", into a usable form to be taken up by plants. Between 5 and 10 billion kg per year are fixed by lightning strikes, but most fixation is done by free-living or symbiotic bacteria known as diazotrophs. These bacteria have the nitrogenase enzyme that combines gaseous nitrogen with hydrogen to produce ammonia, which is converted by the bacteria into other organic compounds. Most biological nitrogen fixation occurs by the activity of Mo-nitrogenase, found in a wide variety of bacteria and some Archaea. Mo-nitrogenase is a complex two-component enzyme that has multiple metal-containing prosthetic groups.[22] An example of free-living bacteria is Azotobacter. Symbiotic nitrogen-fixing bacteria such as Rhizobium usually live in the root nodules of legumes (such as peas, alfalfa, and locust trees). Here they form a mutualistic relationship with the plant, producing ammonia in exchange for carbohydrates. Because of this relationship, legumes will often increase the nitrogen content of nitrogen-poor soils. A few non-legumes can also form such symbioses.
The correct answer is c.stops after infancy and childhood.
Myelin is the substance of the central nervous system (CNS) that insulates nerve cell axons to increase the speed at which nerve impulse travels. Myelination is a process of myelin formation. This process occurs postnatally, begins in the embryo during the midst of early development and finishes after birth.
