1 answer:

8 0

In mutualism, both organisms benefit. In commensalism, one benefits and the other is unaffected; in parasitism, one benefits and the other is harmed. Some of these relationships are so close that we speak of the composite of two species as one unit; for example, we speak of the composite of algae and fungi as lichens

Shalnov [3]

Igneous rocks are formed by hot melted magma coming from the Earth's core that crystalizes when gets in contact with air. They can be either intrusive or extrusive. B) <em>Large mineral crystals.</em>

<h3>What is the igneous rock?</h3>

These rocks come straight from the interior of the Earth.

A liquid mass of silicate composition comes from the Earth's core. This melted mass comes at an extremely high temperature.

Magma begins to cool and solidify during its ascent to the Earth's surface. It solidifies and crystallizes into igneous rock following the magnetic field orientation.

Thre are two types of igneous rocks

• plutonic rocks ⇒ in areas close to the terrestrial crust ⇒ intrusive

• volcanic rocks ⇒ on the surface ⇒ extrusive

According to this description, the correct option is B. <em>Large mineral </em><em>crystals</em><em>.</em>

Short segments of newly synthesized DNA are joined into a continuous strand by _____.Short segments of newly synthesized DNA are

Sloan [31]

Answer:

a. Ligase

b. Ligase ( it's repeated)

Explanation:

DNA synthesis begins, therefore, by synthesizing a short segment of RNA called a primer, which primer is synthesized by an enzyme called Primasa. Primasa is an RNA polymerase that uses DNA as a template. All fragments of Okazaki begin with a Primer. Subsequently, the DNA polymerase III Holoenzyme performs the synthesis of the corresponding DNA fragment until it reaches the next primer. At that time, DNA polymerase Ia replaces the DNA polymerase Holoenzyme III. The DNA polymerase I is responsible for removing the RNA primer through its 5'P-3'OH exonueotic activity and at the same time fills the hole by synthesizing DNA.

Finally, the two Okazaki fragments have to be joined, it is necessary to link the 3'OH end of a fragment with the 5'P of the next fragment. This work of sealing and joining the successive fragments is done by Ligase.
