Answer:
Low concentration to high concentration
Explanation:
If moving up the concentration gradient, you will start detecting the chemical molecules more and more frequently.
Answer:
DNA ligase
Explanation:
<em>The biochemist must have left out DNA ligase enzyme.</em>
<u>The DNA ligase enzyme is able to catalyze the formation of phosphodiester bonds and as such, capable of joining strands of DNA together to form a single strand.</u>
The numerous DNA segments of a few nucleotides long observed by the biochemist must have been the replicated product of the lagging DNA strand. The lagging strand is replicated discontinuously in short strands because the DNA polymerase enzyme can only elongate primers in 5' to 3' direction. The short segments are known as Okazaki segments and are usually joined together to form a whole strand by the DNA ligase enzyme.
Hence, the missing component is the DNA ligase.
Answer: a. Haploid spores are released to form zygotes, which grow into gametophytes.
A fern has two different stages of the life cycle; the sporophyte and gametophyte. In the sporophyte, spores are released. After this life cycle comes the gametophyte or the sexual phase, <span>haploid spores are released to form zygotes, which grow into gametophytes. </span>

Answer:
precipitation and temperature
Explanation:
Temperature and water are considered major abiotic factors that affect species distribution in terrestrial ecosystems. The temperature can affect the distribution of terrestrial organisms due to many species maintain a constant internal temperature, while other species maintain a body temperature range that may be very different from the environmental temperature, and therefore they will not be able to carry out their metabolic functions. Hibernation is an adaptation that allows some terrestrial animals to escape temperature fluctuations. Moreover, water is another limiting factor for life, since water is critical for cellular processes. The waxy cuticle is an adaptation that allows terrestrial plants to avoid excessive water loss through transpiration.
