The correct option is C.
Scientists believed that the earth tectonic plates are in constant motion, this motion is slow and its rates vary. The motions of the tectonic plates are caused by the convection current which is found in semi molten mantle. The convection current are created by heat within the earth surface. When a semi molten rock is heated, it become less in density compared to its surrounding and thus rises up. When the less dense molten rock reaches the crust above, it spread out and carries the tectonic plate above with it. When the molten magma cools down, it sinks and the whole process is repeated leading to continuous movement of the tectonic plates.

In a situation where the concentration of solute is low inside the cell, the cell will be referred to as a hypotonic cell. The transport in this type is referred to as active transport.

<h3>What is active transport?</h3>

The movement of dissolved molecules into or out of a cell via the cell membrane, from a low concentration region to a high concentration region is referred to as active transport.

These particles use the energy released during respiration to move against the concentration gradient.

Thus, in a situation where the concentration of solute is low inside the cell, the cell will be referred to as a hypotonic cell. The transport in this type is referred to as active transport.

Plant roots absorb ammonium ions and nitrate ions for use in making molecules such as DNA, amino acids, and proteins
Scorpion4ik [409]

Answer:

Assimilation

Explanation:

Plant roots absorb ammonium ions and nitrate ions in the process of assimilation to use these ions to make molecules like <em>DNA, amino acids, and proteins</em>.

Animals cannot absorb these ions directly; hence they need to consume these plants for the nutrient supplies.

What are the advantages to using prokaryotic as host systems for genetic engineering? What are the limitations to genetic engine
ahrayia [7]

Answer and Explanation:

The manipulation of the gene is called genetic engineering. In genetic engineering, fragments of genes are cloned by leading the genes into the host cell. The advantage of using a prokaryotic host system in genetic engineering is that bacterial cells are used to produce commercially significant products. For example, human growth hormone helps to treat dwarfism, and human insulin production, which is used to treat diabetes. The bacterium P.putida is created by genetic engineering, which is used to break down petroleum products. Genetic engineering also carries some potential risks, such as transferring the selected gene into another speice, benefit one species can harm another speice. Therefore genetic engineering must be used in limit in prokaryotes. These limitations are also addressable in single-cell eukaryotic systems. Biologics-based therapeutic medicines such as a vaccine, gene therapies, and cell therapies known as bioproduction are produced. Medicines are so complex that they can only be formed in a living system. Biopharmaceuticals, value-added food, fuels, chemicals, antibiotics, and many other products are produced by bioproduction.
