Answer:
the spiders if they get eaten by the lizards they cat eat the smaller insects that harm plants
Explanation:
Answer:
Global warming may cause more icebergs to melt than are created. This would lead to higher sea levels. Sea levels may rise above land masses located at low elevations. As a result, the animals who lived in these areas may find their habitats shrinking and resources depleting, causing their population size to decrease. If there are particular species that were only able to survive in the areas now covered by water, they may very well become extinct.
Answer:
2. have no negative particle
Explanation:
Helium atoms contains 2 neutrons and 2 protons (or 2 electrons). Thus, it has a mass number of 4 and atomic number of 2.
Alpha particles are heavy and positively charged, which make them to be deflected in a magnetic or electric charge. So, the helium atoms used as alpha particles for the gold foil experiment must have no negative particle.
Answer:
D) It decreases water movement.
Explanation:
Humus is known as part of the soil formation. It is characterized by various qualities some of which include containing nutrients such as nitrogen. It is also characterized by its ability to retain water content or soil moisture. Humus is made from the decays of plants wastes such as leaves.
Hence, in this case, the correct answer is Humus is important because "It decreases water movement."
The answer is; A & C
The lagging strand is replicated in fragments called Okazaki fragments, each initiated by a primer. The fragments are later joined into one strand by DNA ligase. Replication occurs by adding nucleotides to the 3’ end of a preceding nucleotide. Because the lagging strand is antiparallel to the leading strand, the replication of the lagging strand is in the opposite direction as the replication fork direction. This is why the lagging strand is replicated in fragments because replication is being carried out by a single DNA polymerase (moving in the direction of the replication fork) per replication fork.
