Answer:

In DNA replication, gaps between newly synthesized segments of DNA and existing segments of DNA are sealed by enzymes called<u> ligases</u>, which form covalent bonds between the two segments.

Explanation:

During DNA replication, there is a continuous strand of DNA and fragments of DNA called Okazaki fragments. The DNA ligase will join the Okazaki fragments using ATP's energy and creating a covalent bond between the phosphate of a nucleotide in an Okazaki fragment and the sugar of a nucleotide in another Okazaki fragment. As a result, there are two continuous DNA fragments.

Which of these is NOT an interaction between a plant's root and shoot systems?
olga_2 [115]

Answer:

The stomata open to allow carbon dioxide to enter the leaves.

Explanation:

Higher plants are made up of two major system parts namely: shoot system and root system. The shoot system constitutes every part of the plant above the ground i.e leaves, fruits, stem etc. while the root system constitutes the part below ground i.e the roots. The shoot system and root system, however, interacts in several ways to ensure that the plant functions optimally. The ways they interact include:

- The roots (root system) absorb water from the soil, which is transported upwards to prevent leaves (shoot system) from drying up.

- The phloem, which is a conducting tissue, transports sugars (product of photosynthesis) from the leaves (shoot system) to the root nodules (root system) for storage.

- Nutrients are absorbed from the soil by the roots (root system) and moved to the stems (shoot system).

Note that, although it is true that "stomata in the leaves open to allow carbon dioxide to enter the leaves", there is no connection between the shoot and root system.

What do you notice about the two molecules?
anastassius [24]

Answer:

If it's in the table, it's an element! Atoms can join together - they form bonds together - to make MOLECULES. For example, two atoms of hydrogen hook together to form a molecule of hydrogen, H2 for short.
